Definitions

  • the present invention relates to an ammonia release prevention and removal device, and more particularly, to a device for preventing and removing leaked toxic ammonia from being released into the atmosphere.
  • Ammonia has been widely used as a refrigerant, and in recent years, the use of ammonia as a carbon dioxide-free fuel is increasing.
  • Ammonia (NH 3 ) composed of only nitrogen and hydrogen may be directly used as a fuel for internal combustion engines.
  • ammonia may be directly used as a fuel for internal combustion engines.
  • it may be used in the form of hydrogen after ammonia is decomposed into nitrogen and hydrogen through a reactor.
  • hydrogen generated by renewable energy is reacted with nitrogen to synthesize ammonia, and then the hydrogen is transported in the form of ammonia to consumers who need it, so that hydrogen is produced in the consumer's reactor.
  • ammonia is harmful to the human body even at a low concentration of 25ppm (0.0025%), and is highly toxic enough to cause death if a person is exposed to 2000ppm (0.2%) for 30 minutes. Therefore, when ammonia leaks from a facility that stores or treats ammonia, it can be a fatal hazard to drivers or people around them.
  • Ammonia which is toxic, is highly reactive, so rapid detection is not difficult.
  • the detection efficiency will naturally increase if the detectors are densely arranged over a large area, but if the number of detectors is excessively large, the cost of equipment or operation will also increase, requiring more careful consideration.
  • Preventing entry into drivers' residential areas is a passive safety measure.
  • arrange the driver's living area and ammonia facilities to have a sufficient distance, and adopt a method of blocking air inflow into the driver's living area when ammonia leakage is detected.
  • Air dilution is in the same vein as the method used for leaks of combustible gases such as natural gas and LPG. Even flammable gases can be safely used without risk of fire or explosion if diluted with air below the explosive concentration. That is, ammonia, which is a toxic gas, can be diluted with air to such an extent that toxicity is not exerted. However, since ammonia has both flammability and very strong toxicity as described above, it is difficult to apply the air dilution method.
  • FIG. 1 and 2 show a schematic configuration of a conventional leak prevention device for indoor/outdoor facilities of combustible non-toxic gas, and explain in detail the flammable gas air dilution method and also the reason why it is difficult to apply to ammonia dilution explain in detail.
  • FIG. 1 shows an outdoor equipment leakage prevention device, which allows leaked gas to be naturally diluted by air (wind), and can be regarded as practically not having a separate device.
  • a shut-off valve is installed at the inlet and outlet of the facility to close the shut-off valve when leakage occurs.
  • devices or controls such as employing explosion-proof equipment or reducing the possibility of ignition by reducing the electrical supply to the system may be further applied.
  • Figure 2 shows a device for preventing leaks in indoor facilities, and when gas leaks occur in a space accommodating facilities, it is configured to be diluted through forced ventilation and exhausted to the outside through a duct. That is, the facility accommodating space is provided with a ventilation inlet and a ventilation outlet each equipped with a switch, and the ventilation outlet is provided with a blower to force exhaust toward the duct, and as a result, the leaked gas is released into the atmosphere through the duct and diluted. is to make it
  • devices or controls such as explosion-proof equipment, ignition possibility reduction control, shut-off valve, etc. can be further used. Supply is very important.
  • the lower explosion limit concentration is 5%, and therefore, fire or explosion can be prevented by supplying air about 20 times the leakage amount.
  • ammonia even at a concentration of 2000 ppm, or 0.2%, it is very toxic enough to cause death if a person is exposed for more than 30 minutes. It is, of course, very difficult to realize these operating conditions. That is, in the case of ammonia, if the conventional leakage prevention device applied to combustible gas is applied as it is, a very high concentration of ammonia is discharged as it is based on the safety level in the atmosphere through the duct, which is a great danger to the driver and the surrounding public environment It will become.
  • ammonia since ammonia has not only flammability but also very strong toxicity, it is not technically easy to dilute the toxicity to a negligible level. Moreover, in an emergency situation where ammonia leaks, such an air dilution method is more difficult because equipment failure, fire, explosion, etc. may coexist.

Description

암모니아 방출방지 및 제거장치Ammonia release prevention and removal device
본 발명은 암모니아 방출방지 및 제거장치에 관한 것으로, 보다 상세하게는 누출된 독성 암모니아의 대기로의 방출을 방지하고 이를 제거하는 장치에 관한 것이다.The present invention relates to an ammonia release prevention and removal device, and more particularly, to a device for preventing and removing leaked toxic ammonia from being released into the atmosphere.
암모니아는 냉매로서 널리 사용되어 왔으며, 근래에는 이산화탄소 무방출 연료로서 암모니아의 사용이 증가하고 있다. 질소와 수소로만 구성된 암모니아(NH3)는 내연기관의 연료로 직접 사용될 수도 있으며, 이러한 예시로서 발전소 선박 차량 항공기 등에서 암모니아를 연료로 사용하는 시도가 있었으며, 현재에도 기술개발 중이다. 다른 방법으로, 반응기를 통해서 암모니아가 질소와 수소로 분해된 후에 수소의 형태로 사용될 수도 있다. 이러한 예시로서 재생에너지로 발생한 수소를 질소와 반응시켜 암모니아를 합성한 후, 수소가 필요한 소비자에게 암모니아 형태로 운송되어 소비자의 반응기에서 수소가 생산되도록 하는 방식으로 사용되기도 한다.Ammonia has been widely used as a refrigerant, and in recent years, the use of ammonia as a carbon dioxide-free fuel is increasing. Ammonia (NH 3 ) composed of only nitrogen and hydrogen may be directly used as a fuel for internal combustion engines. As such, attempts have been made to use ammonia as a fuel in power plants, ships, vehicles, and aircraft, and the technology is currently under development. Alternatively, it may be used in the form of hydrogen after ammonia is decomposed into nitrogen and hydrogen through a reactor. As an example of this, hydrogen generated by renewable energy is reacted with nitrogen to synthesize ammonia, and then the hydrogen is transported in the form of ammonia to consumers who need it, so that hydrogen is produced in the consumer's reactor.
이처럼 암모니아는 다양한 활용예가 있으나, 독성이 있다는 점 때문에 그 사용범위의 확장에 한계가 있는 실정이다. 암모니아는 25ppm (0.0025%)의 낮은 농도만으로도 인체에 유해하며, 사람이 2000ppm (0.2%)에 30분 노출될 경우 사망할 수 있을 정도로 높은 독성을 가지고 있다. 따라서, 암모니아를 저장하거나 처리하는 설비에서 암모니아가 누출될 경우, 운전자나 주위 사람들에게 치명적인 위험이 될 수 있다.As such, although there are various examples of use of ammonia, there is a limit to the expansion of its use range due to its toxicity. Ammonia is harmful to the human body even at a low concentration of 25ppm (0.0025%), and is highly toxic enough to cause death if a person is exposed to 2000ppm (0.2%) for 30 minutes. Therefore, when ammonia leaks from a facility that stores or treats ammonia, it can be a fatal hazard to drivers or people around them.
암모니아 누출에 대응하는 종래 기술은 크게 빠른 감지, 공기에 의한 희석, 운전자 거주 지역으로의 유입 방지 등으로 나눌 수 있다. 각각에 대하여 간략히 설명하면 다음과 같다.Conventional techniques for dealing with ammonia leakage can be largely divided into rapid detection, dilution by air, and prevention of inflow into the driver's living area. A brief description of each is as follows.
독성인 암모니아는 반응성이 좋아서 빠른 감지는 어렵지 않다. 다만, 넓은 공간에서 국부적인 암모니아 누출을 신속하게 감지하기 위한 감지기 배치가 중요하다. 여기에서 감지 자체만을 목적으로 한다면 감지기를 넓은 면적에 촘촘하게 배치하면 당연히 감지효율이 올라가겠지만, 지나치게 감지기 개수가 많아질 경우 설비나 운용에 드는 비용 또한 상승하게 되어 보다 세심한 고려가 필요하게 된다.Ammonia, which is toxic, is highly reactive, so rapid detection is not difficult. However, it is important to arrange a detector to quickly detect local ammonia leakage in a large space. Here, if the purpose of detection is only for itself, the detection efficiency will naturally increase if the detectors are densely arranged over a large area, but if the number of detectors is excessively large, the cost of equipment or operation will also increase, requiring more careful consideration.
운전자 거주 지역으로의 유입 방지는 수동적인 안전 대책이다. 암모니아 대기 방출을 고려하여 운전자 거주 지역과 암모니아 설비가 충분한 거리를 가지도록 배치하고, 암모니아 누출 감지 시에는 운전자 거주 지역으로 공기 유입을 차단하는 방법을 채용한다.Preventing entry into drivers' residential areas is a passive safety measure. In consideration of atmospheric emission of ammonia, arrange the driver's living area and ammonia facilities to have a sufficient distance, and adopt a method of blocking air inflow into the driver's living area when ammonia leakage is detected.
공기에 의한 희석은 천연가스, LPG와 같은 가연성 가스 누출에 사용되는 방법과 동일한 맥락이다. 가연성 가스라 하여도 폭발농도 이하로 공기와 희석되면 화재나 폭발 위험이 없고 안전하게 사용될 수 있다. 즉 독성 가스인 암모니아도 독성이 발휘되지 못할 만큼 공기와 희석되게 하면 된다. 그러나 암모니아는 가연성과 더불어 앞서 설명한 바와 같이 매우 강한 독성을 모두 가지고 있기 때문에 공기희석방식을 적용하기에 어려움이 있다. 도 1 및 도 2는 종래의 가연성 비독성 가스의 실내/실외설비 누출방지장치의 개략적인 구성을 도시하고 있으며, 이를 통해 가연성 가스 공기희석방식을 구체적으로 설명하고, 또한 암모니아 희석에 적용하기 어려운 이유를 상세히 설명한다.Air dilution is in the same vein as the method used for leaks of combustible gases such as natural gas and LPG. Even flammable gases can be safely used without risk of fire or explosion if diluted with air below the explosive concentration. That is, ammonia, which is a toxic gas, can be diluted with air to such an extent that toxicity is not exerted. However, since ammonia has both flammability and very strong toxicity as described above, it is difficult to apply the air dilution method. 1 and 2 show a schematic configuration of a conventional leak prevention device for indoor/outdoor facilities of combustible non-toxic gas, and explain in detail the flammable gas air dilution method and also the reason why it is difficult to apply to ammonia dilution explain in detail.
도 1은 실외설비 누출방지장치를 도시한 것으로, 누출된 가스가 단순히 공기(바람)에 의해 자연스럽게 희석되도록 하는 것으로서 실질적으로 별도의 장치가 없다고도 볼 수 있다. 다만 도시된 바와 같이 누출되는 양을 줄이기 위하여 설비 입출구에 차단밸브를 설치하여 누출 발생 시에 차단밸브를 닫는 정도의 장치가 보조적으로 구비되기도 한다. 또한 방폭장비를 채용하거나, 시스템에 전기공급을 줄여 점화가능성을 줄이는 등의 장치나 제어가 더 적용되기도 한다.1 shows an outdoor equipment leakage prevention device, which allows leaked gas to be naturally diluted by air (wind), and can be regarded as practically not having a separate device. However, as shown, in order to reduce the amount of leakage, a shut-off valve is installed at the inlet and outlet of the facility to close the shut-off valve when leakage occurs. In addition, devices or controls such as employing explosion-proof equipment or reducing the possibility of ignition by reducing the electrical supply to the system may be further applied.
도 2는 실내설비 누출방지장치를 도시한 것으로, 설비를 수용하고 있는 공간에서 가스누출이 발생하면 강제환기를 통해 희석시켜 덕트를 통해 외부로 배기시키는 형태로 구성된다. 즉 설비수용공간에는 각각 개폐기가 구비되는 환기입구 및 환기출구가 구비되며, 환기출구는 송풍기가 구비되어 덕트를 향해 강제배기를 하도록 이루어짐으로써, 결과적으로 누출된 가스가 덕트를 통해 대기로 방출되어 희석되도록 하는 것이다. 이러한 장치에서도 앞서의 실외설비 누출방지장치에서와 마찬가지로, 방폭장비, 점화가능성 저감제어, 차단밸브 등의 장치나 제어가 더 사용될 수 있으며, 특히 설비수용공간에서 폭발하한농도를 유지할 수 있도록 공기를 충분히 공급시켜 주는 것이 매우 중요하다. 예시적으로, LNG의 경우 폭발하한농도는 5%이며, 따라서 누출량의 20배 정도의 공기를 공급하면 화재나 폭발을 방지할 수 있다.Figure 2 shows a device for preventing leaks in indoor facilities, and when gas leaks occur in a space accommodating facilities, it is configured to be diluted through forced ventilation and exhausted to the outside through a duct. That is, the facility accommodating space is provided with a ventilation inlet and a ventilation outlet each equipped with a switch, and the ventilation outlet is provided with a blower to force exhaust toward the duct, and as a result, the leaked gas is released into the atmosphere through the duct and diluted. is to make it In this device, as in the previous outdoor equipment leak prevention device, devices or controls such as explosion-proof equipment, ignition possibility reduction control, shut-off valve, etc. can be further used. Supply is very important. Illustratively, in the case of LNG, the lower explosion limit concentration is 5%, and therefore, fire or explosion can be prevented by supplying air about 20 times the leakage amount.
그런데, 암모니아의 경우 2000ppm 즉 0.2% 농도만 되어도 사람이 30분 이상 노출되면 사망에 이를 정도로 독성이 매우 강하며, 독성이 없는 수준인 0.0025% 수준으로 낮추기 위해서는 40,000배의 공기를 공급해야 하는데 실질적으로 이러한 동작조건을 실현하기란 당연히 매우 어렵다. 즉 암모니아의 경우에 종래의 가연성 가스에 적용되는 누출방지장치를 그대로 적용한다면, 덕트를 통해 대기 중에 안전수준을 기준으로 할 때, 매우 고농도의 암모니아가 그대로 배출되게 되어 운전자 및 주위 공중환경에 커다란 위험이 되는 것이다.However, in the case of ammonia, even at a concentration of 2000 ppm, or 0.2%, it is very toxic enough to cause death if a person is exposed for more than 30 minutes. It is, of course, very difficult to realize these operating conditions. That is, in the case of ammonia, if the conventional leakage prevention device applied to combustible gas is applied as it is, a very high concentration of ammonia is discharged as it is based on the safety level in the atmosphere through the duct, which is a great danger to the driver and the surrounding public environment It will become.
이처럼 암모니아는 가연성 뿐만 아니라 매우 강한 독성을 가지고 있기 때문에, 독성을 무시할만한 수준으로 희석하는 것이 기술적으로 쉽지 않다. 더욱이, 암모니아가 누출되는 비상 상황에서는 장비 고장, 화재, 폭발 등이 병존할 수 있으므로 이러한 공기희석방식은 더욱 어렵다. As such, since ammonia has not only flammability but also very strong toxicity, it is not technically easy to dilute the toxicity to a negligible level. Moreover, in an emergency situation where ammonia leaks, such an air dilution method is more difficult because equipment failure, fire, explosion, etc. may coexist.
이처럼 종래의 암모니아 방출방지 및 제거장치는 충분히 안전한 수준으로 암모니아를 제거하고 있지 못하고 있으며, 이러한 문제점을 해소한 개선된 암모니아 방출방지 및 제거장치의 개발이 시급한 실정이다.As such, conventional ammonia release prevention and removal devices do not remove ammonia at a sufficiently safe level, and it is urgent to develop an improved ammonia release prevention and removal device that solves these problems.

이하, 상기한 바와 같은 구성을 가지는 본 발명에 의한 암모니아 방출방지 및 제거장치를 첨부된 도면을 참고하여 상세하게 설명한다. 본 발명은 하기 실시예에 한정되지 아니하며, 적용범위가 다양함은 물론이고, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 본 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이다.Hereinafter, an apparatus for preventing and removing ammonia according to the present invention having the configuration described above will be described in detail with reference to the accompanying drawings. The present invention is not limited to the following examples, and the scope of application is diverse, and anyone having ordinary knowledge in the field to which the present invention pertains can use various It goes without saying that modifications are possible.
[1] 본 발명의 암모니아 방출방지 및 제거장치 공통구성[1] Common configuration of the ammonia release prevention and removal device of the present invention
먼저 설명하자면, 본 발명의 암모니아 방출방지 및 제거장치(100A)(100B)(100C)는 기본적으로 외곽밀폐벽(110), 덕트(120), 흡수탱크(130A)(130B)(130C)를 포함하되, 크게 제A, B, C실시예로 나뉜다.First of all, the ammonia release prevention and removal devices 100A, 100B, and 100C of the present invention basically include an outer enclosure wall 110, a duct 120, and an absorption tank 130A, 130B, and 130C. However, it is largely divided into Examples A, B and C.
모든 실시예에서, 본 발명의 암모니아 방출방지 및 제거장치(100A)(100B)(100C)는, 상기 외곽밀폐벽(110) 내부공간의 기체가 상기 흡수탱크(130A)(130B)(130C)를 통과하여 상기 덕트(120)를 통해 방출되게 형성된다. 이에 따라 상기 암모니아 사용설비(500) 주변공기 중 암모니아가 상기 흡수탱크(130A)(130B)(130C)에 수용된 암모니아 흡수액에 흡수되어 제거된 상태로 대기방출될 수 있게 된다. 따라서 이 중 상기 외곽밀폐벽(110) 및 상기 덕트(120)는 제A, B, C실시예 모두에서 공통적이되, 상기 흡수탱크(130A)(130B)(130C) 자체 또는 연결관계의 차이로 제A, B, C실시예가 나뉘게 된다.In all embodiments, in the ammonia release prevention and removal devices 100A, 100B, and 100C of the present invention, the gas in the inner space of the outer enclosure wall 110 passes through the absorption tanks 130A, 130B, and 130C. It passes through and is formed to be discharged through the duct 120. Accordingly, ammonia in the air around the ammonia using facility 500 is absorbed into the ammonia absorption liquid contained in the absorption tanks 130A, 130B, and 130C, so that it can be discharged into the air in a removed state. Therefore, the outer enclosure wall 110 and the duct 120 are common to all of the A, B, and C embodiments, but due to differences in the absorption tanks 130A, 130B, and 130C or the connection relationship. Examples A, B, and C are divided.
이에, 먼저 모든 실시예에서 공통적인 구성, 즉 상기 외곽밀폐벽(110) 및 상기 덕트(120)의 세부구성을 간략히 설명하고, 이후 각 실시예별로 상기 흡수탱크(130A)(130B)(130C) 자체 또는 연결관계의 장치적 구성 및 그에 따라 실시예별로 달라지는 방법적 구성에 대하여 상세히 설명하기로 한다.Therefore, first, the configuration common to all embodiments, that is, the detailed configuration of the outer enclosure wall 110 and the duct 120 will be briefly described, and then the absorption tanks 130A, 130B, and 130C for each embodiment. A device configuration of itself or a connection relationship and a methodological configuration that differs for each embodiment will be described in detail.
상기 외곽밀폐벽(110) 및 이에 구비되는 장치들에 대하여 설명한다.The outer enclosure wall 110 and devices provided therewith will be described.
상기 외곽밀폐벽(110)은 암모니아 사용설비(500) 둘레에 구비되어, 상기 암모니아 사용설비(500) 공간을 외부환경과 차단하는 역할을 한다. 한편 상기 암모니아 사용설비(500)에는, 앞서 도 1, 도 2의 종래기술에서와 마찬가지로 차단밸브(550) 등이 구비되어 누출 발생 시 공급을 차단하여 그 자체적으로 누출량을 저감하도록 할 수 있다.The outer enclosure wall 110 is provided around the ammonia using facility 500 and serves to block the space of the ammonia using facility 500 from the external environment. On the other hand, the ammonia using facility 500 is provided with a shut-off valve 550, etc., as in the prior art of FIGS. 1 and 2, to cut off the supply when leak occurs, so that the leak amount can be reduced by itself.
기본적으로 상기 외곽밀폐벽(110)에는, 환기유입로(111), 환기배출로(112), 외곽밀폐벽가스감지기(113)가 구비된다.Basically, the outer enclosure wall 110 includes a ventilation inlet 111, a ventilation outlet 112, and an outer enclosure wall gas detector 113.
상기 환기유입로(111) 및 상기 환기배출로(112)는 상기 외곽밀폐벽(110) 내부공간으로 공기를 환기시킬 수 있도록 하는 것이다. 보다 구체적으로 설명하자면, 먼저 상기 환기유입로(111)는 상기 외곽밀폐벽(110)에 구비되어 공기를 유입시키며 환기유입로개폐기(111d)(제A, B실시예) 또는 환기유입로밸브(111v)(제C실시예)에 의해 개폐가능하게 형성된다. 또한 상기 환기배출로(112)는 상기 외곽밀폐벽(110)에 구비되어 환기배출로개폐기(112d)(제A, B실시예) 또는 환기배출로밸브(112v)(제C실시예)에 의해 개폐가능하게 형성된다. 상기 환기유입로(111) 및 상기 환기배출로(112)를 통해 공기가 환기되도록 하는 구동력은 (이후 설명될) 이들과 연통된 다른 공기통로 상의 송풍기에서 인가될 수 있으며, 물론 필요에 따라 상기 환기유입로(111) 또는 상기 환기배출로(112)에 환기유입로송풍기(111f) 또는 환기배출로송풍기(112f)와 같은 별도의 송풍기가 구비될 수도 있다.The ventilation inlet 111 and the ventilation outlet 112 allow air to be ventilated into the inner space of the outer enclosure wall 110 . To be more specific, first, the ventilation inlet 111 is provided in the outer enclosure wall 110 to introduce air, and the ventilation inlet opener 111d (A and B embodiments) or the ventilation inlet valve ( 111v) (Embodiment C). In addition, the ventilation discharge path 112 is provided on the outer enclosure wall 110 and is provided by the ventilation discharge path switch 112d (Embodiments A and B) or the ventilation discharge path valve 112v (Embodiment C). It is formed to be openable. The driving force for ventilating air through the ventilation inlet 111 and the ventilation outlet 112 may be applied from a blower on another air passage communicating with them (to be described later), and, of course, the ventilation as needed. A separate blower such as a ventilation inlet blower 111f or a ventilation outlet blower 112f may be provided in the inlet 111 or the ventilation outlet 112 .
상기 외곽밀폐벽(110) 내부공간 상측에 구비되는 상기 외곽밀폐벽가스감지기(113)에 의해, 상기 외곽밀폐벽(110) 내부로 누출된 암모니아 가스를 감지할 수 있다. 이후 보다 상세히 설명되겠지만 상기 외곽밀폐벽(110) 내부공간으로는 암모니아를 흡수하는 흡수액이 유입될 수 있는데, 액체 상태의 흡수액은 하부공간으로 깔리게 되므로, 상기 외곽밀폐벽가스감지기(113)가 불필요하게 흡수액에 침수되지 않을 수 있도록 상기 외곽밀폐벽가스감지기(113)가 상측에 구비되도록 하는 것이다.Ammonia gas leaked into the outer wall 110 can be detected by the outer wall gas detector 113 provided on the upper side of the inner space of the outer wall 110 . Although it will be described in more detail later, an absorption liquid for absorbing ammonia may flow into the inner space of the outer enclosure wall 110. Since the liquid absorbent liquid is laid down in the lower space, the outer enclosure wall gas detector 113 is unnecessary. It is to ensure that the outer enclosure wall gas detector 113 is provided on the upper side so that it is not submerged in the absorbent.
부가적으로 상기 외곽밀폐벽(110)에는, 배수조(114), 외곽밀폐벽내부흡수액분사기(115), 공기주입기(116) 등이 더 구비될 수 있다. 상기 배수조(114)는 상기 외곽밀폐벽(110) 내부공간에 흘러들어온 흡수액이 모여서 수용되도록 하기 위한 장치로서, 상기 외곽밀폐벽(110) 내부공간 하면 일부에 함몰 형성되며, 배수조배수밸브(114v)에 의해 배수 여부가 조절된다. 상기 외곽밀폐벽내부흡수액분사기(115)는 상기 외곽밀폐벽(110) 내부공간의 잔존 암모니아 가스를 제거하기 위해 흡수액을 분사하는 역할을 한다. 상기 공기주입기(116)는 압력감지기(116p)에 의해 감지된 상기 외곽밀폐벽(110) 내부공간 압력이 대기압을 유지하도록 상기 외곽밀폐벽(110) 내부에 공기를 주입하는 역할을 한다(제A, B실시예). 또한 상기 외곽밀폐벽(110) 내부공간 밀폐 시 공기순환을 구동하는 역할도 할 수 있다(제C실시예). 이에 대해서 이후 암모니아 방출방지 및 제거방법 설명 시 보다 상세히 설명한다.Additionally, a water tank 114, an absorbent liquid sprayer 115 inside the outer enclosure wall, an air injector 116, and the like may be further provided in the outer enclosure wall 110. The drainage tank 114 is a device for collecting and receiving the absorbent liquid flowing into the inner space of the outer sealing wall 110, and is formed in a depression on a part of the lower surface of the inner space of the outer sealing wall 110, and the drain tank drain valve ( 114v) controls the drainage. The outer enclosure wall internal absorbent liquid injector 115 serves to inject the absorbent liquid to remove ammonia gas remaining in the inner space of the outer enclosure wall 110 . The air injector 116 serves to inject air into the outer enclosure wall 110 so that the pressure in the inner space of the outer enclosure wall 110 sensed by the pressure sensor 116p maintains atmospheric pressure (A , Example B). In addition, it can also serve to drive air circulation when the inner space of the outer wall 110 is closed (Embodiment C). This will be described in more detail when ammonia emission prevention and removal methods are described later.
상기 덕트(120) 및 이에 구비되는 장치들에 대하여 설명한다.The duct 120 and devices provided therewith will be described.
상기 덕트(120)에는 상시 공기흐름이 형성되어 대기로 공기를 방출할 수 있도록 이루어진다. 암모니아가 누출되지 않은 평상상태에서는, 상기 환기유입로(111) 및 상기 환기배출로(112), 또한 이후 설명될 덕트복귀로(132B)(제B실시예), 공기배기로(137C) 또는 덕트연통로(121)(제C실시예)가 개방되어 있으므로, 상기 외곽밀폐벽(110) 내부공간이 상기 덕트(120)와 연통되어 자연스러운 환기가 상시 이루어질 수 있게 된다.Air flow is always formed in the duct 120 so that air can be discharged into the atmosphere. In a normal state in which ammonia is not leaked, the ventilation inlet 111 and the ventilation outlet 112, a duct return path 132B (Embodiment B), an air exhaust path 137C, or a duct to be described later Since the communication passage 121 (Embodiment C) is open, the inner space of the outer enclosure wall 110 communicates with the duct 120, so that natural ventilation can be made at all times.
상기 덕트연통로(121)는 모든 실시예에서 상기 덕트(120) 및 상기 환기배출로(112)를 연결하는 역할을 한다. 다만 각 실시예별로 상기 흡수탱크(130A)(130B)(130C) 자체구성 또는 연결관계가 약간씩 달라지며, 상기 덕트연통로(121)도 이에 따라 약간씩 부가구성이 달라질 수 있다. 상기 덕트연통로(121)에 대하여 실시예별로 간략하게 설명하면 다음과 같다.The duct communication passage 121 serves to connect the duct 120 and the ventilation discharge passage 112 in all embodiments. However, the absorption tanks 130A, 130B, and 130C have a slightly different configuration or connection relationship for each embodiment, and the duct communication passage 121 may also have a slightly different additional configuration accordingly. A brief description of the duct communication passage 121 for each embodiment is as follows.
제A실시예에서, 도 3에 잘 도시된 바와 같이, 상기 덕트연통로(121)는 상기 덕트(120) 및 상기 환기배출로(112)를 연결하며 덕트연통로개폐기(121d)에 의해 개폐가능하게 형성된다. 상기 환기배출로(112)와 구분하는 이유는, 제A실시예의 경우 암모니아 누출 발생 시 상기 덕트연통로(121)에는 흡수액이 채워지게 되기 때문이다. 이 때 상기 환기배출로(112)에 공급된 흡수액이 상기 외곽밀폐벽(110) 내부공간으로 흘러들어가는 것을 배제하도록, 도시된 바와 같이 상기 덕트연통로(121)가 상기 환기배출로(112)보다 하측에 배치되도록 한다. 더불어 상기 덕트연통로(121)에는, 상기 덕트연통로(121)에 채워진 흡수액의 배수 여부를 조절하는 덕트연통로배수밸브(121r)가 구비되도록 한다.In Embodiment A, as well shown in FIG. 3, the duct communication passage 121 connects the duct 120 and the ventilation discharge passage 112 and can be opened and closed by the duct communication passage opener 121d. it is formed The reason why it is distinguished from the ventilation discharge path 112 is that, in the case of Example A, when ammonia leaks, the duct communication path 121 is filled with an absorbent liquid. At this time, the duct communication passage 121 is longer than the ventilation discharge passage 112 as shown to exclude the absorption liquid supplied to the ventilation discharge passage 112 from flowing into the inner space of the outer enclosure wall 110. be placed on the lower side. In addition, the duct communication passage 121 is provided with a duct communication passage drain valve 121r for controlling whether or not to drain the absorption liquid filled in the duct communication passage 121.
제B실시예에서, 도 11에 잘 도시된 바와 같이, 상기 외곽밀폐벽(110) 내부공간의 공기가 상기 흡수탱크(130B)를 통과하여 상기 덕트복귀로(132B)를 통해 상기 덕트(120)로 환기되며, 즉 공기는 최종적으로 상기 덕트(120)를 통해 외부로 배출되게 된다. 그러나 암모니아가 누출되지 않은 평상상태에서는 굳이 상기 흡수탱크(130B)를 통과해야만 할 필요가 없으며, 따라서 평상상태에서 공기가 직접 상기 덕트(120)를 통해 배출되게 할 수도 있다. 도 12가 바로 이러한 응용구성을 도시한 것으로서, 도 12의 응용구성에서는, 상기 암모니아 방출방지 및 제거장치(100B)가, 상기 덕트(120) 및 상기 환기배출로(112)를 연결하며 덕트연통로개폐기(121d)에 의해 개폐가능하게 형성되는 덕트연통로(121)를 더 포함하고 있다. 물론 도 12의 실시예에서는 암모니아 누출 발생 시에는 상기 덕트연통로개폐기(121d)가 폐쇄되어 암모니아가 섞인 공기가 외부로 배출되지 못하도록 막아줄 필요가 있다. 부연하자면, 제B실시예의 덕트연통로(121)는 제A실시예의 덕트연통로(121)와 실질적으로 동등하므로, 실시예별 도면부호를 구분하지 않고 공통으로 사용한다.In the B embodiment, as well shown in FIG. 11 , the air in the inner space of the outer enclosure wall 110 passes through the absorption tank 130B and enters the duct 120 through the duct return path 132B. is ventilated, that is, the air is finally discharged to the outside through the duct 120. However, in a normal state in which ammonia is not leaked, there is no need to pass through the absorption tank 130B, and thus air may be discharged directly through the duct 120 in a normal state. 12 shows such an application configuration. In the application configuration of FIG. 12, the ammonia release prevention and removal device 100B connects the duct 120 and the ventilation discharge passage 112 and is a duct communication passage A duct communication passage 121 formed to be opened and closed by the opener 121d is further included. Of course, in the embodiment of FIG. 12, when ammonia leaks, it is necessary to close the duct communication path opener 121d to prevent the ammonia-mixed air from being discharged to the outside. To elaborate, since the duct communication passage 121 of the B embodiment is substantially equivalent to the duct communication passage 121 of the A embodiment, reference numerals for each embodiment are commonly used without distinction.
제C실시예에서, 상기 외곽밀폐벽(110) 내부공간에서 암모니아 누출 미발생 시에는 상시 공기흐름이 형성되는 상기 덕트(120)로 환기가 이루어지게 한다. 반면 상기 외곽밀폐벽(110) 내부공간에서 암모니아 누출 발생 시에는, 상기 외곽밀폐벽(110) 및 상기 흡수탱크(130C) 공간 / 외부환경 및 상기 덕트(120) 공간을 서로 완전히 격리되게 하여, 암모니아가 원천적으로 외부로 배출되지 못하도록 한다. 보다 구체적으로 설명하자면, 상기 외곽밀폐벽(110) 내부공간에서 암모니아 누출 미발생 시, 상기 암모니아 방출방지 및 제거장치(100C)는, 상기 환기유입로(111)를 통해 상기 외곽밀폐벽(110) 내부공간으로 유입된 공기가 상기 환기배출로(112), 상기 흡수탱크(130C), 상기 공기배기로(137C)를 순차적으로 통과하여 상기 덕트(120)를 통해 외부로 배출됨으로써 환기되는 정상운전모드로 운전된다. 즉 암모니아 누출 발생 시에는 상기 덕트(120)는 완전히 격리되므로, 상기 덕트(120)에는 별도의 암모니아 제거를 위한 장치가 구비되지 않아도 된다.In the C embodiment, when no leakage of ammonia occurs in the inner space of the outer enclosure wall 110, ventilation is performed through the duct 120 where air flow is always formed. On the other hand, when ammonia leaks in the inner space of the outer enclosure wall 110, the outer enclosure wall 110 and the absorption tank 130C space / external environment and the duct 120 space are completely isolated from each other, so that ammonia is fundamentally prevented from being discharged to the outside. More specifically, when ammonia leakage does not occur in the inner space of the outer enclosure wall 110, the ammonia release prevention and removal device 100C, through the ventilation inlet 111, the outer enclosure wall 110 Normal operation mode in which the air introduced into the inner space is ventilated by sequentially passing through the ventilation outlet 112, the absorption tank 130C, and the air exhaust passage 137C and being discharged to the outside through the duct 120. is driven by That is, since the duct 120 is completely isolated when ammonia leakage occurs, a separate device for removing ammonia does not need to be provided in the duct 120.
또한 제C실시예에서, 상술한 바와 같이 암모니아 누출 미발생 시에는 상기 외곽밀폐벽(110) 내부공간의 공기가 상기 덕트(120)를 통해 환기되므로, 굳이 상기 흡수탱크(130C)를 거쳐가지 않아도 된다. 도 20은 본 발명의 암모니아 방출방지 및 제거장치 제C실시예 제1응용구성으로서, 공기가 상기 흡수탱크(130C)를 거치지 않고 직접 상기 덕트(120)로 배출될 수 있도록 하는 덕트연통로(121)가 구비되는 응용구성이다. 구체적으로 설명하자면, 도 20의 제1응용구성에서의 상기 덕트연통로(121)는, 상기 환기배출로(111) 및 상기 덕트(120)를 연결하는 환기통로로서, 상기 외곽밀폐벽(110) 내 공기를 덕트연통로송풍기(121f)에 의해 강제송풍하여 상기 덕트(120)를 통해 배출시키며 덕트연통로밸브(121v)에 의해 개폐가능하게 형성된다. 따라서 이 경우에는, 상기 외곽밀폐벽(110) 내부공간에서 암모니아 누출 미발생 시, 상기 환기유입로(111)를 통해 상기 외곽밀폐벽(110) 내부공간으로 유입된 공기가 상기 환기배출로(112), 상기 덕트연통로(121)를 순차적으로 통과하여 상기 덕트(120)를 통해 외부로 배출됨으로써 환기가 이루어질 수 있게 된다.In addition, in the C embodiment, as described above, when ammonia does not leak, the air in the inner space of the outer enclosure wall 110 is ventilated through the duct 120, so there is no need to pass through the absorption tank 130C. do. 20 is a duct communication passage 121 that allows air to be discharged directly to the duct 120 without passing through the absorption tank 130C as a first applied configuration of the ammonia release prevention and removal device of embodiment C of the present invention. ) is an application configuration provided. Specifically, the duct communication passage 121 in the first application configuration of FIG. 20 is a ventilation passage connecting the ventilation discharge passage 111 and the duct 120, and the outer enclosure wall 110 The internal air is forcibly blown by the duct communication passage blower 121f and discharged through the duct 120, and is formed to be opened and closed by the duct communication passage valve 121v. Therefore, in this case, when ammonia leakage does not occur in the inner space of the outer enclosure wall 110, the air introduced into the inner space of the outer enclosure wall 110 through the ventilation inlet 111 is transferred to the ventilation outlet 112. ), passing through the duct communication passage 121 sequentially and being discharged to the outside through the duct 120, ventilation can be achieved.
상기 덕트(120)에는 또한, 상기 덕트(120) 내부공간의 잔존 암모니아 가스를 제거하기 위해 흡수액을 분사하는 덕트내부흡수액분사기(122)가 더 구비될 수 있다.The duct 120 may further include an absorbent liquid injector 122 for spraying an absorbent liquid in order to remove residual ammonia gas in the inner space of the duct 120 .
부가적으로, 상기 흡수액에 대하여 보다 상세히 설명한다. 상기 흡수액으로는 암모니아의 용해도가 높은 액체라면 무엇이든 사용가능한데, 예를 들어 물, 산성수, 에탄올, 글리콜 등이 채용될 수 있다. 도 25는 암모니아의 물에 대한 용해도를, 도 26은 암모니아의 에탄올에 대한 용해도를, 도 27은 암모니아의 글리콜에 대한 용해도를 각각 나타내고 있다. 물은 암모니아 용해도가 높을뿐더러 가격이 저렴하고 구하기 쉬운 장점이 있다. 또한 암모니아는 염기성이기 때문에, 산성수를 이용하면 용해도를 더욱 높일 수 있다. 그러나 온도가 낮은 암모니아의 경우 물은 응결가능성이 있다는 단점이 있어, 그 외의 선택지가 필요할 수 있다. 도 26, 27을 참조하면, 에탄올, 글리콜 모두 온도가 낮은 암모니아의 경우에 원활하게 사용할 수 있음을 알 수 있다. 물론 상술한 물질들이 반드시 단독으로 사용되어야 할 필요는 없으며, 필요에 따라 적절히 이들이 혼합되어 사용되어도 무방하다.Additionally, the absorbent liquid will be described in more detail. As the absorption liquid, any liquid having high ammonia solubility may be used, and for example, water, acidic water, ethanol, glycol, and the like may be employed. FIG. 25 shows the solubility of ammonia in water, FIG. 26 shows the solubility of ammonia in ethanol, and FIG. 27 shows the solubility of ammonia in glycol. Water has a high ammonia solubility, and has the advantage of being cheap and easy to obtain. In addition, since ammonia is basic, the solubility can be further increased by using acidic water. However, in the case of low-temperature ammonia, water has the disadvantage of condensation, so other options may be needed. 26 and 27, it can be seen that both ethanol and glycol can be smoothly used in the case of ammonia having a low temperature. Of course, the above-mentioned materials do not necessarily have to be used alone, and they may be appropriately mixed and used as needed.

2-2. 제A실시예에 따른 암모니아 방출방지 및 제거방법 기본실시예2-2. Method for preventing and removing ammonia according to Example A Basic Example
이하에서, 상술한 바와 같은 본 발명의 암모니아 방출방지 및 제거장치(100A)를 사용하는 암모니아 방출방지 및 제거방법에 대하여 단계적으로 상세히 설명한다. 본 발명의 암모니아 방출방지 및 제거방법 기본실시예는, 암모니아 누출 발생 시 수행되는 누출가스감지단계, 흡수탱크연결단계, 암모니아제거단계를 포함하며, 이후 평상상태로 되돌아가기 위해 수행되는 잔존가스제거단계, 평상상태복구단계, 평상복구완료단계를 더 포함할 수 있다.Hereinafter, the ammonia emission prevention and removal method using the ammonia emission prevention and removal device 100A of the present invention as described above will be described in detail step by step. A basic embodiment of the ammonia release prevention and removal method of the present invention includes a leak gas detection step, an absorption tank connection step, and an ammonia removal step performed when ammonia leak occurs, and then a residual gas removal step performed to return to a normal state , a normal state recovery step, and a normal restoration completion step may be further included.
먼저 암모니아 누출 발생 시 순차적으로 수행되는 누출가스감지단계, 흡수탱크연결단계, 암모니아제거단계 각각을 도면을 참조하여 보다 상세히 설명한다.First, each of the leak gas detection step, the absorption tank connection step, and the ammonia removal step, which are sequentially performed when ammonia leak occurs, will be described in more detail with reference to the drawings.
도 5는 본 발명의 암모니아 방출방지 및 제거장치의 누출가스감지단계 시 장치 구성을 도시한 것이다. 상기 누출가스감지단계에서는, 상기 외곽밀폐벽가스감지기(113)에 의해 누출된 암모니아 가스가 감지되어, 상기 환기유입로개폐기(111d), 상기 덕트연통로개폐기(121d)가 폐쇄된다. 평상상태에서는 상기 환기유입로개폐기(111d), 상기 덕트연통로개폐기(121d)가 개방된 상태에 있음으로써 상기 외곽밀폐벽(110) 내부공간이 자연스럽게 상기 덕트(120)를 통해 환기될 수 있도록 되어 있었으나, 암모니아 누출이 발생하면 외부 대기로 독성을 가진 암모니아가 방출될 수 있으므로, 일단 상기 외곽밀폐벽(113) 내부공간을 외부와 차단하도록 상기 환기유입로개폐기(111d), 상기 덕트연통로개폐기(121d)가 폐쇄되는 것이다.Figure 5 shows the device configuration during the leak gas detection step of the ammonia release prevention and removal device of the present invention. In the leak gas detection step, leaked ammonia gas is detected by the outer enclosure wall gas detector 113, and the ventilation inlet opener 111d and the duct communication passage opener 121d are closed. In a normal state, the ventilation inlet switch 111d and the duct communication passage switch 121d are in an open state so that the inner space of the outer enclosure wall 110 can be naturally ventilated through the duct 120 However, if ammonia leakage occurs, toxic ammonia may be released into the external atmosphere, so the ventilation inlet opener 111d and the duct communication path opener (111d) to block the inner space of the outer enclosure wall 113 from the outside ( 121d) is closed.
도 6은 본 발명의 암모니아 방출방지 및 제거장치의 흡수탱크연결단계 시 장치 구성을 도시한 것이다. 상기 흡수탱크연결단계에서는, 상기 환기배출로개폐기(112d), 상기 흡수액공급로개폐기(131Ad), 상기 덕트복귀로개폐기(132Ad)는 개방됨으로써, 상기 흡수액공급로(131A)를 통해 상기 덕트연통로(121)로 흡수액이 채워진다. 여기에서, 평상상태에서도 이미 상기 환기배출로개폐기(112d), 상기 덕트복귀로개폐기(132Ad)는 개방되어 있었으므로 이들은 동작에 변화가 없되, 폐쇄되어 있던 상기 흡수액공급로개폐기(131Ad)가 개방됨으로써 상기 흡수탱크(130A) 내에 수용되어 있던 흡수액이 상기 덕트연통로(121)로 흘러내려와 채워지게 된다.Figure 6 shows the device configuration during the absorption tank connection step of the ammonia release prevention and removal device of the present invention. In the step of connecting the absorption tank, the ventilation outlet switch 112d, the absorbent liquid supply passage switch 131Ad, and the duct return switch 132Ad are opened to pass through the absorbent liquid supply passage 131A to the duct communication passage. (121) is filled with absorbent liquid. Here, since the ventilation discharge path switch 112d and the duct return path switch 132Ad are already open even in the normal state, there is no change in their operation, but the closed absorbent liquid supply path switch 131Ad is opened. The absorption liquid contained in the absorption tank 130A flows down into the duct communication passage 121 and is filled therein.
이 때, 만일 도시된 바와 달리 상기 덕트연통로(121)가 상기 환기배출로(112)와 비슷한 높이에 있거나 더 높게 배치된다면, 흡수액이 상기 덕트연통로(121)에만 채워지는 것이 아니라 상기 환기배출로(112)를 통해 상기 외곽밀폐벽(110) 내부공간으로 쏟아져들어가게 될 것이다. 이러할 경우 상기 암모니아 사용설비(500)가 흡수액에 잠겨 침수될 수 있으며, 이는 설비 고장 위험성을 크게 증가시키게 된다. 따라서 이러한 문제를 방지하기 위해, 상기 환기배출로(112)에 공급된 흡수액이 상기 외곽밀폐벽(110) 내부공간으로 흘러들어가는 것을 배제하도록, 상기 덕트연통로(121)가 상기 환기배출로(112)보다 하측에 배치되도록 하는 것이다.At this time, unlike the drawing, if the duct communication passage 121 is at a height similar to or higher than the ventilation discharge passage 112, the absorption liquid is not only filled in the duct communication passage 121, but also the ventilation discharge passage 121. It will pour into the inner space of the outer enclosure wall 110 through the furnace 112. In this case, the ammonia using facility 500 may be submerged in the absorption liquid and flooded, which greatly increases the risk of facility failure. Therefore, in order to prevent this problem, the duct communication passage 121 is installed in the ventilation discharge passage 112 to exclude the absorption liquid supplied to the ventilation discharge passage 112 from flowing into the inner space of the outer enclosure wall 110. ) to be placed lower than
물론 그렇게 한다 하더라도 약간의 흡수액이 상기 외곽밀폐벽(110)으로 넘쳐들어갈 수 있을 가능성은 있다. 이러한 경우 상기 외곽밀폐벽(110) 내부공간에 흘러들어온 흡수액이 모여서 수용되도록 하는 상기 배수조(114)가 구비됨으로써, 상기 암모니아 사용설비(500)를 보다 확실하게 보호할 수 있게 된다.Of course, even if so, there is a possibility that some absorbent liquid may overflow into the outer sealing wall 110 . In this case, the ammonia use equipment 500 can be more reliably protected by the provision of the drainage tank 114 for collecting and accommodating the absorbent liquid flowing into the inner space of the outer enclosure wall 110 .
도 6의 상태에서 상기 환기배출로송풍기(112f)가 상기 외곽밀폐벽(110) 내부공간의 공기를 상기 환기배출로(112) 쪽으로 강제송풍함으로써, 상기 암모니아제거단계가 이루어지게 된다. 상기 암모니아제거단계에서는, 상기 환기배출로(112)를 통해 배출된 암모니아 및 공기의 혼합물이 상기 덕트연통로(121)에 채워진 흡수액과 접촉하여 상기 흡수탱크(130A)를 통과하게 된다. 도 6에서, 공기의 흐름은 진한 화살표로, 암모니아의 흐름은 연한 화살표로 표시되어 있다. 이처럼 암모니아 및 공기의 혼합물이 상기 흡수탱크(130A)를 통과하는 과정에서 암모니아가 흡수액에 용해되어 제거되고, 상기 흡수탱크(130A)를 통과하면서 암모니아가 제거되어 정제된 공기가 상기 덕트복귀로(132A)를 통해 외부로 배출될 수 있게 된다.In the state of FIG. 6 , the ammonia removal step is performed by forcibly blowing the air in the inner space of the outer enclosure wall 110 toward the ventilation discharge passage 112 by the ventilation discharge passage blower 112f. In the ammonia removal step, the mixture of ammonia and air discharged through the ventilation outlet 112 comes into contact with the absorption liquid filled in the duct communication passage 121 and passes through the absorption tank 130A. In FIG. 6, the flow of air is indicated by a thick arrow and the flow of ammonia is indicated by a light arrow. As such, while the mixture of ammonia and air passes through the absorption tank 130A, ammonia is dissolved in the absorption liquid and removed, and ammonia is removed while passing through the absorption tank 130A, and purified air is returned to the duct 132A. ) through which it can be discharged to the outside.
이 과정에서, 암모니아의 제거가 보다 효과적으로 이루어질 수 있도록, 상기 외곽밀폐벽내부흡수액분사기(115) 및 상기 덕트내부흡수액분사기(122)가 흡수액을 분사함으로써 공기 중의 암모니아가 분사된 흡수액으로 흡수되도록 하는 것이 바람직하다. 한편 흡수액이 암모니아를 흡수하여 암모니아가 차지하던 만큼의 부피가 줄어듦에 따라 상기 외곽밀폐벽(110) 내부공간 압력이 대기압보다 낮아지면 아무리 강제송풍을 해도 공기가 외부로 배출되기 어려워질 수 있으므로, 상기 공기주입기(116)가 상기 압력감지기(116p)에 의해 감지된 상기 외곽밀폐벽(110) 내부공간 압력이 대기압을 유지하도록 상기 외곽밀폐벽(110) 내부에 공기를 주입하도록 할 수 있다. 더불어 상기 흡수탱크(130A)에 상기 정제공기배기로(134A)가 구비될 경우, 상기 덕트(120)를 굳이 통하지 않더라도 암모니아가 제거된 공기를 직접 외부로 배출시키도록 할 수도 있다.In this process, the absorbent liquid sprayer inside the outer enclosure wall 115 and the absorbent liquid sprayer inside the duct 122 spray absorbent liquid so that ammonia in the air is absorbed into the sprayed absorbent liquid so that ammonia can be removed more effectively. desirable. On the other hand, as the absorption liquid absorbs ammonia and the volume occupied by ammonia decreases, if the pressure in the outer space of the outer enclosure wall 110 is lower than atmospheric pressure, it may be difficult for air to be discharged to the outside no matter how forcedly blown. The air injector 116 may inject air into the outer enclosure wall 110 so that the pressure of the inner space of the outer enclosure wall 110 sensed by the pressure sensor 116p maintains atmospheric pressure. In addition, when the purified air exhaust path 134A is provided in the absorption tank 130A, the ammonia-removed air may be directly discharged to the outside without passing through the duct 120.
본 발명에서는 이처럼 암모니아 누출 발생 시 누출가스감지단계, 흡수탱크연결단계, 암모니아제거단계를 순차적으로 수행하여, 암모니아가 혼합된 공기가 외부로 곧바로 배출되지 않고 반드시 흡수액과 접촉하여 통과하도록 함으로써, 공기 중에 혼합된 암모니아가 흡수액에 흡수되어 최대한 제거되도록 한다. 공기가 배출되는 경로는 도시된 바와 같이 상기 흡수탱크(130A) 상측공간에 구비되는 상기 덕트복귀로(132A) 또는 상기 정제공기배기로(134A) 뿐이므로, 배출되는 것은 흡수액을 통과해 온 공기뿐인 바 흡수액에 의해 충분히 암모니아가 제거되기 때문에, 외부로 배출되는 공기의 독성을 매우 효과적으로 안전한 수준까지 낮출 수 있게 된다.In the present invention, when an ammonia leak occurs, the leak gas detection step, the absorption tank connection step, and the ammonia removal step are sequentially performed so that the air mixed with ammonia is not immediately discharged to the outside but must pass through in contact with the absorbent liquid. The mixed ammonia is absorbed into the absorption liquid to be removed as much as possible. As shown in the figure, the path through which air is discharged is only the duct return path 132A or the purified air exhaust path 134A provided in the upper space of the absorption tank 130A, so that only the air that has passed through the absorption liquid is discharged. Since ammonia is sufficiently removed by the bar absorption liquid, the toxicity of the air discharged to the outside can be very effectively reduced to a safe level.
이후 평상상태로 되돌아가기 위해 순차적으로 수행되는 잔존가스제거단계, 평상상태복구단계, 평상복구완료단계 각각을 도면을 참조하여 보다 상세히 설명한다.Thereafter, each of the residual gas removal step, the normal state recovery step, and the normal restoration completion step, which are sequentially performed to return to the normal state, will be described in more detail with reference to the drawings.
도 7은 본 발명의 암모니아 방출방지 및 제거장치의 잔존가스제거단계 시 장치 구성을 도시한 것이다. 상기 잔존가스제거단계에서는, 상기 외곽밀폐벽(110) 내부공간에 잔존된 암모니아 가스가, 상기 공기주입기(116)에 의해 주입된 공기에 의해 흡수액과 강제접촉하여 제거되거나 또는 상기 외곽밀폐벽내부흡수액분사기(115) 및 상기 덕트내부흡수액분사기(122)가 분사한 흡수액에 의해 제거되도록 한다. 흡수액을 분사하는 방식은 직접적으로 잔존 암모니아를 제거할 수 있다는 점에서 직관적이고 편리하지만 제거속도가 다소 느릴 수 있다. 한편 상기 공기주입기(116)를 이용하여 공기를 더 주입하면, 상기 외곽밀폐벽(110) 내부공간 압력이 높아져서 공기가 강제적으로 흡수액이 채워져있는 공간 쪽으로 더 이동하게 되며, 흡수액이 채워진 공간의 부피가 상대적으로 상당히 크기 때문에 잔존 암모니아 가스는 매우 효과적으로 흡수액에 흡수되어 제거될 수 있게 된다.Figure 7 shows the device configuration during the residual gas removal step of the ammonia release prevention and removal device of the present invention. In the residual gas removal step, the ammonia gas remaining in the inner space of the outer enclosure wall 110 is removed by forcible contact with the absorbent liquid by the air injected by the air injector 116 or the outer enclosure wall internal absorbent liquid. The sprayer 115 and the absorbent liquid sprayer 122 inside the duct are removed by the sprayed absorbent liquid. The method of spraying the absorbent is intuitive and convenient in that it can directly remove residual ammonia, but the removal rate may be somewhat slow. On the other hand, when more air is injected using the air injector 116, the pressure in the inner space of the outer sealing wall 110 increases, so that the air is forcibly moved more towards the space filled with the absorbent liquid, and the volume of the space filled with the absorbent liquid increases. Since it is relatively large, the residual ammonia gas can be absorbed and removed very effectively by the absorption liquid.
도 8은 본 발명의 암모니아 방출방지 및 제거장치의 평상상태복구단계 시 장치 구성을 도시한 것이다. 상기 평상상태복구단계에서는, 상기 흡수액공급로개폐기(131Ad)가 폐쇄되고 상기 흡수액주입기(135A)에 의해 상기 흡수탱크(130A)로 흡수액이 보충되고, 상기 배수조배수밸브(114v) 및 상기 덕트연통로배수밸브(121r)가 개방되어 상기 외곽밀폐벽(110) 및 상기 덕트연통로(121)에 채워진 흡수액이 배수된다. 이제 상기 외곽밀폐벽(110) 내부공간의 암모니아 가스가 완전히 제거되었으므로, 상기 암모니아 사용설비(500)가 동작 가능한 상태로 되돌리기만 하면 된다. 따라서 불필요하게 남아있는 흡수액은 배수되어 제거되도록 하고, 상기 흡수탱크(130A)에서 배출되어 부족해진 흡수액은 보충해 주는 단계를 거치는 것이다.Figure 8 shows the device configuration during the normal state recovery step of the ammonia release prevention and removal device of the present invention. In the normal state recovery step, the absorbent liquid supply path switch 131Ad is closed, the absorbent liquid is replenished to the absorbent tank 130A by the absorbent liquid injector 135A, and the drain tank drain valve 114v and the duct communicate with each other. The furnace drain valve 121r is opened, and the absorbent liquid filled in the outer enclosure wall 110 and the duct communication passage 121 is drained. Now that the ammonia gas in the inner space of the outer enclosure wall 110 is completely removed, the ammonia using facility 500 only needs to be returned to an operable state. Accordingly, the absorbent liquid that remains unnecessarily is drained and removed, and the absorbent liquid that is insufficient after being discharged from the absorption tank 130A is replenished.
도 9는 본 발명의 암모니아 방출방지 및 제거장치의 평상복구완료단계 시 장치 구성을 도시한 것이다. 상기 평상복구완료단계에서는, 흡수액 배수가 완료된 이후 상기 환기유입로개폐기(111d), 상기 덕트연통로개폐기(121d)가 개방되어 평상상태로의 복구가 완료된다. 즉 암모니아 누출이 없는 상태에서 자연스러운 환기가 이루어지는 원래의 상태로 되돌아가게 되는 것이다.Figure 9 shows the device configuration at the normal recovery completion stage of the ammonia release prevention and removal device of the present invention. In the normal restoration completion step, after the absorbent liquid is completely drained, the ventilation inlet opening and closing device 111d and the duct communication passage opening and closing device 121d are opened to complete the restoration to the normal state. That is, it returns to the original state in which natural ventilation is made in the absence of ammonia leakage.
이처럼 본 발명에 의하면, 암모니아 누출이 발생한다 하더라도 앞서의 누출가스감지단계, 흡수탱크연결단계, 암모니아제거단계를 순차적으로 수행함으로써 외부로 방출되는 공기의 독성을 안전한 수준까지 효과적으로 제거할 수 있으며, 또한 그 이후에는 잔존가스제거단계, 평상상태복구단계, 평상복구완료단계가 순차적으로 수행됨으로써 평소의 원래 상태로 매우 원활하게 되돌아갈 수 있다.As described above, according to the present invention, even if ammonia leakage occurs, the toxicity of the air emitted to the outside can be effectively removed to a safe level by sequentially performing the leak gas detection step, the absorption tank connection step, and the ammonia removal step. After that, the residual gas removal step, the normal state recovery step, and the normal state restoration completion step are sequentially performed, so that the normal state can be returned very smoothly.
2-3. 제A실시예에 따른 암모니아 방출방지 및 제거방법 응용실시예2-3. Ammonia release prevention and removal method application example according to Example A
도 10은 본 발명의 암모니아 방출방지 및 제거장치의 가압식 외곽밀폐벽 및 가압식 흡수탱크벽 응용구성으로서, 앞서 설명한 본 발명의 암모니아 방출방지 및 제거방법 기본실시예와 비슷하나 약간 다른 부분이 있는, 본 발명의 암모니아 방출방지 및 제거방법의 응용실시예를 설명하기 위한 도면이다.10 is a pressurized outer enclosure wall and a pressurized absorption tank wall application configuration of the ammonia release prevention and removal device of the present invention, similar to the basic embodiment of the ammonia release prevention and removal method of the present invention described above, but with slightly different parts, this It is a drawing for explaining an application embodiment of the ammonia release prevention and removal method of the present invention.
앞서 설명한 기본실시예에서는, 상기 외곽밀폐벽(110)에 직접적으로 공기가 유통되는 경로 즉 상기 환기유입로(111), 상기 덕트연통로(121)는 폐쇄되었지만, 공기가 흡수액을 통과하여 유통되는 경로 즉 상기 덕트복귀로(132A)는 개방됨으로써 암모니아가 제거된 공기가 상기 덕트(120)를 통해 자연스럽게 배출될 수 있도록 하였다. 응용실시예에서는, 이와는 달리 상기 덕트복귀로(132A)까지 폐쇄됨으로써, 상기 외곽밀폐벽(110)이 완전 밀폐가 이루어지도록 한다는 점에서 기본실시예와 상이하다.In the basic embodiment described above, the path through which air is directly circulated through the outer enclosure wall 110, that is, the ventilation inflow path 111 and the duct communication path 121 are closed, but the air passes through the absorption liquid and circulates. The path, that is, the duct return passage 132A is opened so that the ammonia-removed air can be naturally discharged through the duct 120. The application embodiment differs from the basic embodiment in that the outer enclosure wall 110 is completely sealed by being closed up to the duct return path 132A.
응용실시예에서도, 암모니아 누출 발생 시 누출가스감지단계, 흡수탱크연결단계, 암모니아제거단계가 순차적으로 수행된다는 점은 마찬가지이다. 즉 응용실시예에서도, 상기 누출가스감지단계에서는 기본실시예와 동일하게, 상기 외곽밀폐벽가스감지기(113)에 의해 누출된 암모니아 가스가 감지되어, 상기 환기유입로개폐기(111d), 상기 덕트연통로개폐기(121d)가 폐쇄된다.It is the same in the application embodiment that the leakage gas detection step, the absorption tank connection step, and the ammonia removal step are sequentially performed when ammonia leak occurs. That is, in the application embodiment, in the leakage gas detection step, as in the basic embodiment, leaked ammonia gas is detected by the outer enclosure wall gas detector 113, and the ventilation inlet opener 111d, the duct communication The furnace switch 121d is closed.
한편 응용실시예에서는, 흡수탱크연결단계에서 기본실시예에서와는 달리 상기 덕트복귀로개폐기(132Ad)가 더 폐쇄된다. 즉 응용실시예의 상기 흡수탱크연결단계에서는, 상기 덕트복귀로개폐기(132Ad)는 폐쇄되고, 상기 환기배출로개폐기(112d), 상기 흡수액공급로개폐기(131Ad)는 개방됨으로써, 상기 암모니아 사용설비(500) 공간이 외부환경과 완전 차단되며, 상기 흡수액공급로(131A)를 통해 상기 덕트연통로(121)로 흡수액이 채워진다.On the other hand, in the application embodiment, unlike in the basic embodiment, in the step of connecting the absorption tank, the switch 132Ad is further closed by the return of the duct. That is, in the absorption tank connection step of the application embodiment, the duct return path switch 132Ad is closed, and the ventilation discharge path switch 112d and the absorbent liquid supply path switch 131Ad are opened, so that the ammonia use equipment 500 ) The space is completely blocked from the external environment, and the absorbent liquid is filled into the duct communication passage 121 through the absorbent liquid supply path 131A.
기본실시예의 경우 상기 덕트복귀로(132A)가 개방되어 있었기 때문에 공기가 흡수액을 통과하여 외부로 배출됨으로써 상기 외곽밀폐벽(110) 내부공간의 압력이 과도하게 높아질 우려가 없다. 그러나 응용실시예의 경우 상기 덕트복귀로(132A)가 폐쇄됨에 따라 상기 외곽밀폐벽(110) 내부공간이 외부환경과 완전 차단됨으로써, 상기 외곽밀폐벽(110) 내부공간의 압력이 상당히 높아지게 된다. 물론 이에 따라 상기 환기배출로(112)를 통해 흘러가는 공기의 흐름도 기본실시예에서처럼 자연스럽게 이루어지지 못할 수 있다.In the case of the basic embodiment, since the duct return path 132A is open, air is discharged to the outside through the absorbent liquid, so that there is no fear that the pressure in the inner space of the outer enclosure wall 110 is excessively increased. However, in the case of the application embodiment, as the duct return path 132A is closed, the inner space of the outer enclosure wall 110 is completely blocked from the external environment, so that the pressure in the inner space of the outer enclosure wall 110 is significantly increased. Of course, accordingly, the flow of air flowing through the ventilation outlet 112 may not be made naturally as in the basic embodiment.
이러한 점을 고려하여, 응용실시예의 암모니아제거단계에서는, 암모니아 및 공기의 혼합물이 흡수액을 통과하면서 암모니아가 제거되는 것은 마찬가지이되, 상기 환기배출로개폐기(112d)가 암모니아 제거율에 따라 개방도가 조절되도록 제어되며 개방되도록 하여 공기의 흐름이 원활하게 이루어지도록 적절히 제어된다. 즉 명확히 설명하자면, 응용실시예의 암모니아제거단계에서는, 상기 환기배출로개폐기(112d)가 암모니아 제거율에 따라 개방도가 조절되도록 제어되며 개방됨으로써, 상기 환기배출로(112)를 통해 배출된 암모니아 및 공기의 혼합물이 상기 덕트연통로(121)에 채워진 흡수액과 접촉하여 상기 흡수탱크(130A)를 통과하는 과정에서 암모니아가 흡수액에 용해되어 제거되고, 상기 흡수탱크(130A)를 통과하면서 암모니아가 제거되도록 한다.Considering this point, in the ammonia removal step of the application embodiment, ammonia is removed while the mixture of ammonia and air passes through the absorption liquid, but the opening of the ventilation discharge path switch 112d is adjusted according to the ammonia removal rate. It is controlled and opened so that the air flow is properly controlled. That is, in the ammonia removal step of the application embodiment, the ventilation discharge path switch 112d is controlled and opened so that the opening degree is adjusted according to the ammonia removal rate, so that ammonia and air discharged through the ventilation discharge path 112 are opened. Ammonia is dissolved and removed in the process of passing through the absorption tank 130A in contact with the absorption liquid filled in the duct communication passage 121, and ammonia is removed while passing through the absorption tank 130A. .
응용실시예의 경우 암모니아가 제거되는 과정에서 외부환경으로 열려있는 경로가 전혀 없기 때문에, 독성물질이 외부환경으로 전혀 배출되지 않을 수 있다는 장점이 있다. 다만 상술한 바와 같이 상기 외곽밀폐벽(110) 및 상기 흡수탱크(130A)의 내부압력이 상당히 과도하게 높아질 우려가 있다. 따라서 응용실시예의 경우, 상기 외곽밀폐벽(110) 및 상기 흡수탱크(130A)가 내압성을 가지도록 설계되어야 하며, 여러 개폐기들도 내압성을 가지도록 밸브 형태로 선택되어야 하는 등 일부 설계자유도가 저하될 수 있다.In the case of the application embodiment, since there is no path open to the external environment in the process of removing ammonia, there is an advantage in that toxic substances may not be discharged to the external environment at all. However, as described above, there is a possibility that the internal pressure of the outer enclosure wall 110 and the absorption tank 130A may increase significantly. Therefore, in the case of the application embodiment, the outer enclosure wall 110 and the absorption tank 130A must be designed to have pressure resistance, and several switches must be selected in the form of valves to have pressure resistance. can
[3] 본 발명의 암모니아 방출방지 및 제거장치 및 방법 제B실시예[3] Ammonia emission prevention and removal device and method B embodiment of the present invention
도 11~12를 참조하여, 본 발명의 암모니아 방출방지 및 제거장치 제B실시예(100B) 및 제B실시예의 장치에 의한 방법을 상세히 설명한다. 이하의 설명에서, 기재를 간결하게 하기 위하여 "제B실시예"라는 문구는 생략하나, 도 11~12를 참조하며 [3] 단락에 기재된 모든 "암모니아 방출방지 및 제거장치"는 "암모니아 방출방지 및 제거장치 제B실시예"를 가리키는 것임을 미리 고지한다.Referring to Figures 11 and 12, the ammonia emission prevention and removal device of the present invention B embodiment (100B) and the method by the device of the B embodiment will be described in detail. In the following description, the phrase “Example B” is omitted for concise description, but referring to FIGS. and removal device B embodiment".
3-1. 제B실시예에 따른 흡수탱크 관련구성3-1. Configuration related to absorption tank according to embodiment B
상기 흡수탱크(130B) 및 이에 구비되는 장치들에 대하여 설명한다.The absorption tank 130B and devices included therein will be described.
상기 흡수탱크(130B)는 암모니아 흡수액을 수용하는 역할을 하며, 상기 암모니아 사용설비(500)에서 암모니아 누출 발생 시 암모니아가 유통되는 공간으로 흡수액을 공급하여 암모니아를 최대한 흡수시켜 공기로부터 제거할 수 있도록 한다. 이후 보다 상세히 설명되겠지만, 궁극적으로 본 발명에서는 암모니아 및 공기의 혼합물이 그대로 외부로 배출되지 않고 상기 흡수탱크(130B)를 통과하여 배출되도록 한다. 즉 암모니아 및 공기의 혼합물이 진행하면서 상기 흡수탱크(130B) 내의 흡수액과 최대한 접촉하도록 함으로써, 외부로 배출되기 전에 공기 중에 섞여있는 암모니아를 최대한 제거하는 것이다.The absorption tank 130B serves to accommodate the ammonia absorption liquid, and when ammonia leakage occurs in the ammonia using facility 500, the absorption liquid is supplied to the space where ammonia is distributed so that the ammonia can be maximally absorbed and removed from the air. . Although described in more detail later, ultimately, in the present invention, the mixture of ammonia and air is discharged through the absorption tank 130B without being discharged to the outside as it is. That is, as the mixture of ammonia and air proceeds, it is brought into contact with the absorption liquid in the absorption tank 130B as much as possible, so that ammonia mixed in the air is removed as much as possible before being discharged to the outside.
상기 흡수탱크(130B)에는, 기본적으로 탱크연통로(131B), 덕트복귀로(132B), 흡수탱크가스감지기(133B), 흡수액순환펌프(134B)가 구비되며, 암모니아와 흡수액의 접촉을 증가시키기 위하여 흡수액수용부(135B)가 더 구비될 수 있다.The absorption tank 130B is basically provided with a tank communication path 131B, a duct return path 132B, an absorption tank gas detector 133B, and an absorption liquid circulation pump 134B, to increase contact between ammonia and absorption liquid. To this end, an absorbent receiving portion 135B may be further provided.
상기 탱크연통로(131B)는 상기 흡수탱크(130B) 및 상기 환기배출로(112)를 연결하며 탱크연통로개폐기(131Bd)에 의해 개폐가능하게 형성되어, 상기 환기배출로(112)를 통해 흘러온 공기 또는 암모니아 및 공기의 혼합물이 상기 흡수탱크(130B) 내 빈 공간으로 원활하게 유통될 수 있도록 한다. 도시된 바와 같이 상기 탱크연통로(131B)는 상기 흡수탱크(130B) 하측에 채워진 흡수액 수위보다 높은 곳에 형성됨으로서 흡수액이 역류하여 상기 외곽밀폐벽(110) 내부공간으로 흘러들어가지 못하도록 구비되도록 한다. 다만 흡수액이 더 보충될 때 흡수액 수위가 올라가서 흡수액 역류가 발생할 가능성을 완전히 배제할 수는 없으며, 이러한 경우 상기 흡수탱크(130B) 하측에 수용된 흡수액이 상기 외부밀폐벽(110) 내부공간으로 흘러들어가는 것을 배제하도록, (도면 상에 도시되지는 않았으나) 상기 탱크연통로(131B)가 상기 환기배출로(112)보다 하측에 배치되도록 할 수 있다.The tank communication passage 131B connects the absorption tank 130B and the ventilation discharge passage 112 and is formed to be opened and closed by the tank communication passage opener 131Bd, so that the air flowing through the ventilation discharge passage 112 Air or a mixture of ammonia and air can be smoothly circulated into the empty space in the absorption tank 130B. As shown, the tank communication passage 131B is formed at a place higher than the level of the absorbent liquid filled in the lower side of the absorption tank 130B, so that the absorbent liquid does not flow backward and flow into the inner space of the outer enclosure wall 110. However, when the absorbent liquid is further replenished, the possibility that the absorbent liquid level rises and the absorbent liquid reverses occurs cannot be completely ruled out. In order to exclude it, the tank communication passage 131B may be arranged lower than the ventilation discharge passage 112 (although not shown on the drawings).
상기 덕트복귀로(132B)는 상기 흡수탱크(130B) 내 수용된 흡수액 상측공간 및 상기 덕트(120)를 연결하며 덕트복귀로개폐기(132Bd)에 의해 개폐가능하게 형성된다. 상기 흡수탱크(130B)를 통과하면서 암모니아가 제거된 공기는, 상기 덕트복귀로(132B) 및 상기 덕트(120)를 순차적으로 통과하면서 외부로 배출될 수 있게 된다. 이 때 부가적으로 상기 흡수탱크(130B)에는, 정제된 공기를 배출시키며 정제공기배기로개폐기(136Bd)에 의해 개폐가능하게 형성되는 정제공기배기로(136B)가 구비되어, 상기 덕트(120)를 굳이 통하지 않더라도 암모니아가 제거된 공기를 직접 외부로 배출시키도록 할 수도 있다.The duct return path 132B connects the duct 120 and the upper space of the absorption liquid accommodated in the absorption tank 130B, and is formed to be opened and closed by the duct return path switch 132Bd. Air from which ammonia is removed while passing through the absorption tank 130B can be discharged to the outside while sequentially passing through the duct return path 132B and the duct 120 . At this time, the absorption tank (130B) is additionally provided with a purified air exhaust passage (136B) formed to be opened and closed by a purified air exhaust passage switch (136Bd) for discharging purified air, and the duct (120) It is also possible to directly discharge the ammonia-removed air to the outside without having to go through it.
상기 흡수탱크가스감지기(133B)는, 상기 흡수탱크(130B)에 구비되어 상기 흡수탱크(130B) 내 수용된 흡수액 상측공간의 암모니아 농도 또는 흡수액의 pH를 측정하는 역할을 한다. 도 11에서는 상기 흡수탱크가스감지기(133B)가 흡수액 바깥에 구비되어 침수되지 않도록 하는 형태로 도시되어 있으나 반드시 이렇게만 되어야 하는 것은 아니고, 흡수액의 pH를 측정하여 가스를 감지하는 경우 흡수액 수중에 구비되도록 할 수도 있는 등 감지기의 가스감지 원리에 따라 구비위치는 다양하게 달라질 수 있다. 뿐만 아니라 상기 흡수탱크가스감지기(133B)가 단일 개만 구비될 필요는 없으며, 암모니아 제거율 모니터링을 위해, 복수 개의 상기 흡수탱크가스감지기(133B)가 서로 다른 높이로 구비되도록 할 수도 있다.The absorption tank gas sensor 133B is provided in the absorption tank 130B and serves to measure the ammonia concentration in the upper space of the absorption liquid contained in the absorption tank 130B or the pH of the absorption liquid. In FIG. 11, the absorption tank gas detector 133B is shown in a form that is provided outside the absorption liquid to prevent submersion. Depending on the gas detection principle of the detector, the position of the detector may be variously changed. In addition, it is not necessary to have only one absorption tank gas detector 133B, and a plurality of absorption tank gas detectors 133B may be provided at different heights to monitor the ammonia removal rate.
상기 흡수액순환펌프(134B)는, 상기 흡수탱크(130B) 하측에 수용된 흡수액을 끌어올려 상기 흡수탱크(130B) 상측에서 다시 제공하여 순환시키는 흡수액순환유로(134Bp)에 구비되어 흡수액을 펌핑하는 역할을 한다. 암모니아는 기체상태로 누출되며, 암모니아 흡수액은 액체이다. 따라서 상기 흡수탱크(130B)에 액체상태인 흡수액이 그냥 채워져 있기만 하다면, 기체상태인 암모니아 및 공기의 혼합물이 흡수액을 원활하게 통과하기 어려울 수 있다. 이러한 점을 고려하여, 상기 흡수탱크(130B)는 흡수액을 수용하고는 있되 기체가 원활하게 통과할 수 있도록 도시된 바와 같이 내부에 빈 공간이 충분히 형성되어 있는 형태로 이루어지도록 한다. 그러면서도 암모니아와 흡수액이 보다 원활하게 접촉될 수 있도록, 하측에 고여있는 흡수액을 상기 흡수액순환유로(134Bp)를 통해 상기 흡수액순환펌프(134B)로 펌핑하여 끌어올려 상측에서 다시 뿌려주는 식으로 흡수액이 상기 흡수탱크(130B) 내부공간 전체에서 순환될 수 있게 이루어지도록 하는 것이다.The absorbent liquid circulation pump 134B is provided in the absorbent liquid circulation passage 134Bp for pumping the absorbent liquid by lifting the absorbent liquid accommodated in the lower side of the absorption tank 130B and supplying the absorbent liquid from the upper side of the absorber tank 130B to circulate it. do. Ammonia leaks out in a gaseous state, and the ammonia absorption liquid is a liquid. Accordingly, if the absorption tank 130B is filled with the absorption liquid in a liquid state, it may be difficult for the mixture of ammonia and air in a gaseous state to smoothly pass through the absorption liquid. Considering this point, the absorption tank 130B is configured to contain the absorption liquid and have a sufficient empty space therein so that the gas can pass through smoothly. At the same time, so that ammonia and the absorbent liquid can be more smoothly contacted, the absorbent liquid accumulated on the lower side is pumped to the absorbent liquid circulation pump 134B through the absorbent liquid circulation passage 134Bp, raised up, and sprayed again from the upper side. It is to be made so that it can be circulated in the entire inner space of the absorption tank (130B).
한편 상기 흡수액순환펌프(134B)는 언제나 동일한 양을 순환시키도록 할 수도 있겠으나, 평상시 항상 흡수액을 순환시키고 있는 것은 불필요한 에너지 낭비를 초래한다. 따라서 상기 흡수액순환펌프(134B)는, 평상상태에서는 흡수액을 순환시키지 않거나 또는 최소한의 양만 순환시키되, 암모니아 누출이 감지되면 흡수액 순환량을 늘리는 식으로 운영되게 한다. 물론 암모니아가 제거되어 더 이상 감지되지 않으면 다시 평상상태와 같이 최소운전모드로 돌아감으로써 에너지 낭비를 방지한다. 즉 상기 암모니아 방출방지 및 제거장치(100B)는, 상기 외곽밀폐벽가스감지기(113) 또는 상기 흡수탱크가스감지기(133B)에서 감지된 암모니아 누출량에 따라 상기 흡수액순환펌프(134B)가 순환시키는 흡수액 양을 증감하도록 형성되는 것이다.Meanwhile, the absorbent liquid circulation pump 134B may always circulate the same amount, but circulating the absorbent liquid at all times causes unnecessary energy waste. Accordingly, the absorbent liquid circulation pump 134B does not circulate the absorbent liquid or circulates only a minimum amount of the absorbent liquid under normal conditions, but increases the circulation amount of the absorbent liquid when ammonia leakage is detected. Of course, when ammonia is removed and no longer detected, energy waste is prevented by returning to the minimum operation mode as usual. That is, the ammonia release prevention and removal device 100B determines the amount of absorbent liquid circulated by the absorbent liquid circulation pump 134B according to the amount of ammonia leakage detected by the outer enclosure wall gas detector 113 or the absorption tank gas detector 133B. It is formed to increase or decrease.
또한 상기 흡수액순환유로(134Bp) 상에는 상기 흡수액순환유로(134Bp) 상에 새로운 흡수액을 보충하는 흡수액보충로(134Ba) 및 암모니아를 흡수한 흡수액을 외부에서 처리하도록 배출하는 흡수액처리로(134Bb)가 구비되는 것이 바람직하다. 이 때 도면 상에서는 상기 흡수액보충로(134Ba)가 상기 흡수액순환펌프(134B) 후방에, 상기 흡수액처리로(134Bb)가 상기 흡수액순환펌프(134B) 전방에 설치되도록 하고 있으며, 이렇게 하면 상기 흡수액순환펌프(134B)의 펌핑력 효과에 의해 보다 많은 흡수액이 원활하게 펌핑될 수 있는 장점이 있다. 다만 이 경우 새로운 흡수액이 상기 흡수탱크(130B) 내에서 암모니아를 흡수한 흡수액과 섞이게 되며, 또한 이렇게 섞인 흡수액이 상기 흡수액처리로(134Bb)를 통해 일부 배출되는 과정에서 일부의 새로운 흡수액이 상기 흡수탱크(130B) 내로 재순환되지 못하고 그대로 배출될 우려가 있다. 이러한 여러 사정을 고려하여, 상기 흡수액보충로(134Ba) 및 상기 흡수액처리로(134Bb)의 구비위치는 적절하게 변경 설계될 수 있다.In addition, an absorbent liquid replenishment path 134Ba for replenishing a new absorbent liquid on the absorbent liquid circulation path 134Bp and an absorbent liquid processing furnace 134Bb for discharging the absorbent liquid that has absorbed ammonia to be treated externally are provided on the absorbent liquid circulation path 134Bp. it is desirable to be At this time, in the drawing, the absorbent liquid replenishment path 134Ba is installed at the rear of the absorbent liquid circulation pump 134B, and the absorbent liquid treatment path 134Bb is installed in front of the absorbent liquid circulation pump 134B. In this case, the absorbent liquid circulation pump There is an advantage in that more absorbent liquid can be smoothly pumped by the pumping force effect of 134B. However, in this case, the new absorbent liquid is mixed with the absorbent liquid that has absorbed ammonia in the absorption tank 130B, and in the process of partially discharging the mixed absorbent liquid through the absorbent liquid processing furnace 134Bb, some of the new absorbent liquid is transferred to the absorbent liquid in the absorption tank 130B. (130B) there is a concern that it is not recycled and discharged as it is. In consideration of these various circumstances, the location of the absorbent liquid replenishment path 134Ba and the absorbent liquid treatment furnace 134Bb may be appropriately changed and designed.
이와 같은 구성만으로도 물론 암모니아 제거가 가능하지만, 앞서 설명한 바와 같이 암모니아와 흡수액의 접촉을 최대한 증가시킬 수 있도록 하는 것이 바람직하다. 이를 위하여 구비되는 것이 바로 흡수액수용부(135B)로서, 복수 개의 흡수액수용부(135B)는 상기 흡수탱크(130B) 내에 구비되어 흡수액을 분산 수용함으로써 암모니아와 흡수액의 접촉을 더욱 증가시키는 역할을 한다. 상기 흡수액수용부(135B)의 역할 및 그에 따른 배치위치 등에 대해서는, 전체적인 암모니아 처리과정이 설명될 이후의 [2]에서 보다 상세히 설명하기로 한다.Of course, ammonia can be removed with only this configuration, but as described above, it is preferable to increase the contact between ammonia and the absorbent as much as possible. To this end, an absorbent liquid accommodating unit 135B is provided. A plurality of absorbent liquid accommodating units 135B are provided in the absorption tank 130B to disperse and accommodate the absorbent liquid, thereby further increasing the contact between ammonia and the absorbent liquid. The role of the absorbent liquid accommodating part 135B and its location will be described in more detail in [2] , where the overall ammonia treatment process will be described.
더불어 도 11에서는 하나의 상기 흡수탱크(130B)에 하나의 상기 환기배출로(112)가 연결되는 것으로 도시되어 있으나, 이로써 본 발명이 한정되는 것은 아니다. 즉 복수 개의 암모니아 사용설비(500)를 하나의 상기 흡수탱크(130B)로 관리하도록 할 수 있는데, 이러한 경우 하나의 상기 흡수탱크(130B)에 복수 개의 상기 환기배출로(112)가 연결되도록 할 수 있다.In addition, although FIG. 11 shows that one ventilation outlet 112 is connected to one absorption tank 130B, the present invention is not limited thereto. That is, a plurality of ammonia using facilities 500 can be managed by one absorption tank 130B. In this case, a plurality of ventilation outlets 112 can be connected to one absorption tank 130B. there is.
3-2. 제B실시예에 따른 암모니아 방출방지 및 제거방법3-2. Ammonia release prevention and removal method according to Example B
이하에서, 상술한 바와 같은 본 발명의 암모니아 방출방지 및 제거장치(100B)를 사용하는 암모니아 방출방지 및 제거방법에 대하여 단계적으로 상세히 설명한다. 본 발명의 암모니아 방출방지 및 제거방법은, 암모니아 누출 발생 시 수행되는 누출가스감지단계, 흡수액량증가단계, 암모니아제거단계를 포함하며, 이후 평상상태로 되돌아가기 위해 수행되는 잔존가스제거단계, 흡수액량감소단계를 더 포함할 수 있다.Hereinafter, the ammonia emission prevention and removal method using the ammonia emission prevention and removal device 100B of the present invention as described above will be described in detail step by step. The ammonia release prevention and removal method of the present invention includes a leak gas detection step, an absorption liquid amount increase step, and an ammonia removal step performed when ammonia leak occurs, and then a residual gas removal step performed to return to a normal state, and an absorption liquid amount A reduction step may be further included.
먼저 암모니아 누출 발생 시 순차적으로 수행되는 누출가스감지단계, 흡수탱크연결단계, 암모니아제거단계를 보다 상세히 설명한다.First, the leakage gas detection step, the absorption tank connection step, and the ammonia removal step, which are sequentially performed when ammonia leak occurs, will be described in more detail.
상기 누출가스감지단계에서는, 상기 외곽밀폐벽가스감지기(113)에 의해 누출된 암모니아 가스가 감지된다. 평상상태에서는 상기 환기유입로개폐기(111d), 상기 탱크연통로개폐기(131Bd), 상기 덕트복귀로개폐기(132B)가 개방된 상태에 있음으로써 상기 외곽밀폐벽(110) 내부공간이 자연스럽게 상기 덕트(120)를 통해 환기될 수 있도록 되어 있다. 더불어 도 12에서와 같이 상기 암모니아 방출방지 및 제거장치(100B)에 상기 덕트연통로(121)가 구비되는 경우, 역시 평상상태에서는 상기 덕트연통로개폐기(121d)로 개방된 상태에 있어 공기가 상기 덕트(120)를 통해 배출된다. 이 때 암모니아 누출이 발생하면, 상기 흡수탱크(130B)를 통과하는 공기흐름에서는 흡수액과 접촉함으로써 암모니아가 제거되지만, 상기 덕트연통로(121)를 통하는 공기흐름에서는 외부 대기로 독성을 가진 암모니아가 방출될 수 있으므로, 이 경우 상기 누출가스감지단계 이후에, 상기 덕트연통로개폐기(121d)가 폐쇄되는 덕트누출방지단계가 곧바로 수행되도록 한다.In the leak gas detection step, leaked ammonia gas is detected by the outer enclosure wall gas detector 113 . In a normal state, since the ventilation inlet opener 111d, the tank communication path opener 131Bd, and the duct return opener 132B are in an open state, the inner space of the outer enclosure wall 110 naturally changes to the duct ( 120) to allow ventilation. In addition, as shown in FIG. 12, when the ammonia release prevention and removal device 100B is provided with the duct communication passage 121, in the normal state, it is open to the duct communication passage opener 121d, so that the air It is discharged through the duct 120. At this time, if ammonia leakage occurs, ammonia is removed from the airflow passing through the absorption tank 130B by contact with the absorption liquid, but toxic ammonia is released to the outside atmosphere from the airflow passing through the duct communication passage 121. In this case, after the leak gas detection step, the duct leak prevention step in which the duct communication path opener 121d is closed is performed immediately.
상기 흡수액량증가단계에서는, 상기 흡수액순환펌프(134B)가 순환시키는 흡수액 양을 증가시킴으로써 암모니아 및 공기의 혼합물과 흡수액의 접촉을 증가시킨다. 이 때 상기 흡수탱크(130B) 하측에 고여있는 흡수액을 끌어올려 상측에서 뿌려주는 것으로도 암모니아와 흡수액을 접촉시킬 수 있지만, 상기 흡수탱크(130B)에 상기 흡수액수용부(135B)가 더 구비됨으로써 상기 흡수탱크(130B) 내부공간 전체를 충분히 활용하면서 접촉을 더욱 증가시킬 수 있다.In the step of increasing the absorption liquid amount, the contact between the mixture of ammonia and air and the absorption liquid is increased by increasing the amount of the absorbent liquid circulated by the absorbent liquid circulation pump 134B. At this time, although ammonia and the absorption liquid can be contacted by lifting up the absorption liquid accumulated at the lower side of the absorption tank 130B and spraying it from the upper side, the absorption liquid accommodating part 135B is further provided in the absorption tank 130B. Contact can be further increased while fully utilizing the entire inner space of the absorption tank 130B.
상기 암모니아제거단계에서는, 상기 환기배출로(112)를 통해 배출된 암모니아 및 공기의 혼합물이 항기 환기배출로(112) 및 상기 탱크연통로(131B)를 통해 상기 흡수탱크(130B)로 유입되어 통과하게 된다. 이처럼 암모니아 및 공기의 혼합물이 상기 흡수탱크(130B)를 통과하는 과정에서 암모니아가 흡수액에 용해되어 제거되고, 상기 흡수탱크(130B)를 통과하면서 암모니아가 제거되어 정제된 공기가 상기 덕트복귀로(132B)를 통해 외부로 배출될 수 있게 된다.In the ammonia removal step, the mixture of ammonia and air discharged through the ventilation discharge passage 112 flows into the absorption tank 130B through the ventilation discharge passage 112 and the tank communication passage 131B and passes therethrough. will do As such, while the mixture of ammonia and air passes through the absorption tank 130B, ammonia is dissolved in the absorption liquid and removed, and ammonia is removed while passing through the absorption tank 130B, and the purified air is returned to the duct 132B. ) through which it can be discharged to the outside.
즉 암모니아의 효과적인 제거를 위해서는 암모니아와 흡수액의 접촉을 증가시키는 것이 중요하며, 이를 위해 기본적으로 상기 흡수액량증가단계가 수행되어 상기 흡수액순환펌프(134B)가 순환시키는 흡수액 양을 증가시킨다. 뿐만 아니라 복수 개의 상기 흡수액수용부(135B)가 구비됨으로써, 암모니아와 흡수액의 접촉이 더욱 증가된다. 암모니아와 흡수액 접촉이 더욱 효과적으로 이루어지도록 하기 위한 상기 흡수액수용부(135B)의 배치 등에 대하여 설명하자면 다음과 같다.That is, to effectively remove ammonia, it is important to increase the contact between ammonia and the absorbent liquid, and for this purpose, the absorbent liquid amount increasing step is basically performed to increase the absorbent liquid amount circulated by the absorbent liquid circulation pump 134B. In addition, since the plurality of absorption liquid accommodating portions 135B are provided, the contact between ammonia and the absorption liquid is further increased. The arrangement of the absorbent liquid accommodating portion 135B for more effective contact between ammonia and absorbent liquid will be described below.
상기 흡수액수용부(135B)는, 도시된 바와 같이 복수 개가 상기 흡수탱크(130B) 내부공간에 분산 설치된다. 이 때 상기 흡수탱크(130B)는 상하방향으로 길게 연장된 흡수탑 형태로 건설되는 것이 일반적이며, 따라서 복수 개의 상기 흡수액수용부(135B)는 역시 도시된 바와 같이 상하로 이격 배치되도록 할 수 있다. 물론 특수하게 상기 흡수탱크(130B)가 지면에 넓게 퍼진 형태로 건설된다면 복수 개의 상기 흡수액수용부(135B)가 수평방향으로 분산 배치되게 할 수도 있을 것이다. 어쨌든 일반적으로는 상기 흡수탱크는 도 11 및 도 12에 도시된 바와 같이 상하방향으로 길게 연장되는 형태이며, 따라서 복수 개의 상기 흡수액수용부(135B)는 상하로 이격 배치된다. 더불어 상측에 배치된 상기 흡수액수용부(135B)에서 넘친 흡수액이 하측에 배치된 상기 흡수액수용부(135B) 또는 상기 흡수탱크(130B) 하측으로 재수용 가능하도록, 상하로 이격된 상기 흡수액수용부(135B)들끼리 서로 어긋나게 배치되도록 하는 것이 바람직하다.As shown, a plurality of absorbent liquid accommodating portions 135B are distributed and installed in the inner space of the absorption tank 130B. At this time, it is common for the absorption tank 130B to be constructed in the form of an absorption tower elongated in the vertical direction, and therefore, the plurality of absorbent liquid accommodating portions 135B may be vertically spaced apart as shown. Of course, if the absorption tank 130B is specially constructed in a form spread widely on the ground, the plurality of absorbent liquid accommodating portions 135B may be distributed and disposed in the horizontal direction. In any case, generally, the absorption tank has a shape extending vertically as shown in FIGS. 11 and 12, and thus the plurality of absorbent liquid accommodating portions 135B are vertically spaced apart. In addition, the absorbent liquid receiver 135B disposed on the upper side is spaced apart so that the absorbent liquid overflowing from the absorbent liquid receiver 135B disposed on the lower side can be reaccepted to the lower side of the absorbent liquid receiver 135B or the absorption tank 130B ( 135B) is preferably arranged so that they are offset from each other.
도 11 및 도 12에서, 공기의 흐름은 진한 화살표로, 암모니아의 흐름은 연한 화살표로 표시되어 있다. 도 11 및 도 12를 참조하면, 최하측에서는 암모니아 농도가 높았으나, 암모니아 및 공기의 혼합물이 상승하는 과정에서 계속 다른 상기 흡수액수용부(135B)와 만나면서 그 때마다 암모니아가 제거되어, 최종적으로 최상측에서는 암모니아가 완전히 제거되어 정제된 공기만 남게 됨이 알기 쉽게 나타난다. 특히 흡수액은 상측에 있을수록 암모니아와 덜 접촉한 흡수액이라서 더 암모니아를 잘 흡수하도록 설계되어 있으므로, 암모니아 및 공기의 혼합물이 상승할수록 암모니아 제거가 보다 잘 이루어지게 된다.11 and 12, the flow of air is indicated by thick arrows, and the flow of ammonia is indicated by light arrows. Referring to FIGS. 11 and 12, although the ammonia concentration was high at the lowermost side, the ammonia was removed each time as the mixture of ammonia and air continued to rise while encountering the other absorption liquid receiving portion 135B, and finally at the uppermost side. It is readily apparent that the ammonia is completely removed leaving only purified air. In particular, since the absorption liquid is designed to better absorb ammonia because it is less in contact with ammonia as it is located on the upper side, ammonia is better removed as the mixture of ammonia and air rises.
이 과정에서, 암모니아의 제거가 보다 효과적으로 이루어질 수 있도록, 상기 외곽밀폐벽내부흡수액분사기(115) 및 상기 덕트내부흡수액분사기(122)가 흡수액을 분사함으로써 공기 중의 암모니아가 분사된 흡수액으로 흡수되도록 하는 것이 바람직하다. 한편 흡수액이 암모니아를 흡수하여 암모니아가 차지하던 만큼의 부피가 줄어듦에 따라 상기 외곽밀폐벽(110) 내부공간 압력이 대기압보다 낮아지면 아무리 강제송풍을 해도 공기가 외부로 배출되기 어려워질 수 있으므로, 상기 공기주입기(116)가 상기 압력감지기(116p)에 의해 감지된 상기 외곽밀폐벽(110) 내부공간 압력이 대기압을 유지하도록 상기 외곽밀폐벽(110) 내부에 공기를 주입하도록 할 수 있다. 더불어 상기 흡수탱크(130B)에 상기 정제공기배기로(136B)이 구비될 경우, 상기 덕트(120)를 굳이 통하지 않더라도 암모니아가 제거된 공기를 직접 외부로 배출시키도록 할 수도 있다.In this process, the absorbent liquid sprayer inside the outer enclosure wall 115 and the absorbent liquid sprayer inside the duct 122 spray absorbent liquid so that ammonia in the air is absorbed into the sprayed absorbent liquid so that ammonia can be removed more effectively. desirable. On the other hand, as the absorption liquid absorbs ammonia and the volume occupied by ammonia decreases, if the pressure in the outer space of the outer enclosure wall 110 is lower than atmospheric pressure, it may be difficult for air to be discharged to the outside no matter how forcedly blown. The air injector 116 may inject air into the outer enclosure wall 110 so that the pressure of the inner space of the outer enclosure wall 110 sensed by the pressure sensor 116p maintains atmospheric pressure. In addition, when the purified air exhaust path 136B is provided in the absorption tank 130B, the ammonia-removed air may be directly discharged to the outside without passing through the duct 120.
한편 이처럼 상기 외곽밀폐벽(110) 내부에 분사된 흡수액은 상기 외곽밀폐벽(110) 내부공간 하부에 모이게 된다. 또한 상술한 바와 같이 상기 흡수액순환펌프(134B)가 순환시키는 흡수액 양을 증가시킴에 따라 상기 흡수탱크(130B) 내 흡수액 수위가 높아질 수도 있는데, 상기 탱크연통로(131B)가 상기 환기배출로(112)와 동일한 높이에 배치될 경우 예상치 못하게 흡수액이 역류하여 상기 환기배출로(112)를 통해 상기 외곽밀폐벽(110) 내부공간으로 침투할 수도 있다. 이러할 경우 상기 암모니아 사용설비(500)가 흡수액에 잠겨 침수될 수 있으며, 이는 설비 고장 위험성을 크게 증가시키게 된다. 따라서 이러한 문제를 방지하기 위해, 상기 환기배출로(112)에 공급된 흡수액이 상기 외곽밀폐벽(110) 내부공간으로 흘러들어가는 것을 배제하도록, 상기 탱크연통로(131B)가 상기 환기배출로(112)보다 하측에 배치되도록 할 수도 있다.Meanwhile, the absorbent liquid sprayed inside the outer wall 110 is collected in the lower part of the inner space of the outer wall 110. In addition, as described above, as the amount of absorbent liquid circulated by the absorbent liquid circulation pump 134B increases, the level of the absorbent liquid in the absorption tank 130B may increase. ), the absorption liquid may unexpectedly flow backward and penetrate into the inner space of the outer enclosure wall 110 through the ventilation outlet 112. In this case, the ammonia using facility 500 may be submerged in the absorption liquid and flooded, which greatly increases the risk of facility failure. Therefore, in order to prevent this problem, the tank communication passage 131B is provided to prevent the absorption liquid supplied to the ventilation discharge passage 112 from flowing into the inner space of the outer enclosure wall 110. ) may be arranged lower than.
물론 그렇게 한다 하더라도 약간의 흡수액이 상기 외곽밀폐벽(110)으로 넘쳐들어갈 수 있을 가능성은 있다. 이러한 경우 상기 외곽밀폐벽(110) 내부공간에 흘러들어온 흡수액이 모여서 수용되도록 하는 상기 배수조(114)가 구비됨으로써, 상기 암모니아 사용설비(500)를 보다 확실하게 보호할 수 있게 된다.Of course, even if so, there is a possibility that some absorbent liquid may overflow into the outer sealing wall 110 . In this case, the ammonia use equipment 500 can be more reliably protected by the provision of the drainage tank 114 for collecting and accommodating the absorbent liquid flowing into the inner space of the outer enclosure wall 110 .
본 발명에서는 이처럼 암모니아 누출 발생 시 누출가스감지단계, 흡수액량증가단계, 암모니아제거단계를 순차적으로 수행하여, 암모니아가 혼합된 공기가 외부로 곧바로 배출되지 않고 반드시 흡수액과 접촉하여 통과하도록 함으로써, 공기 중에 혼합된 암모니아가 흡수액에 흡수되어 최대한 제거되도록 한다. 공기가 배출되는 경로는 도시된 바와 같이 상기 흡수탱크(130B) 상측공간에 구비되는 상기 덕트복귀로(132B) 또는 상기 정제공기배기로(136B) 뿐이므로, 배출되는 것은 흡수액을 통과해 온 공기뿐인 바 흡수액에 의해 충분히 암모니아가 제거되기 때문에, 외부로 배출되는 공기의 독성을 매우 효과적으로 안전한 수준까지 낮출 수 있게 된다.In the present invention, when ammonia leaks occur, the leak gas detection step, the step of increasing the amount of absorption liquid, and the step of removing ammonia are sequentially performed so that the air mixed with ammonia is not immediately discharged to the outside but must pass through in contact with the absorption liquid. The mixed ammonia is absorbed into the absorption liquid to be removed as much as possible. As shown in the figure, since the path through which air is discharged is only the duct return path 132B or the purified air exhaust path 136B provided in the upper space of the absorption tank 130B, only the air that has passed through the absorption liquid is discharged. Since ammonia is sufficiently removed by the bar absorption liquid, the toxicity of the air discharged to the outside can be very effectively reduced to a safe level.
이후 평상상태로 되돌아가기 위해 순차적으로 수행되는 잔존가스제거단계, 흡수액량감소단계를 보다 상세히 설명한다.Hereafter, the residual gas removal step and the absorption liquid amount reduction step, which are sequentially performed to return to the normal state, will be described in more detail.
상기 잔존가스제거단계에서는, 상기 외곽밀폐벽(110) 내부공간에 잔존된 암모니아 가스가, 상기 공기주입기(116)에 의해 주입된 공기에 의해 흡수액과 강제접촉하여 제거되거나 또는 상기 외곽밀폐벽내부흡수액분사기(115) 및 상기 덕트내부흡수액분사기(122)가 분사한 흡수액에 의해 제거되도록 한다. 흡수액을 분사하는 방식은 직접적으로 잔존 암모니아를 제거할 수 있다는 점에서 직관적이고 편리하지만 제거속도가 다소 느릴 수 있다. 한편 상기 공기주입기(116)를 이용하여 공기를 더 주입하면, 상기 외곽밀폐벽(110) 내부공간 압력이 높아져서 공기가 강제적으로 흡수액이 채워져있는 공간 쪽으로 더 이동하게 되며, 잔존 암모니아 가스는 매우 효과적으로 흡수액에 흡수되어 제거될 수 있게 된다.In the residual gas removal step, the ammonia gas remaining in the inner space of the outer enclosure wall 110 is removed by forcible contact with the absorbent liquid by the air injected by the air injector 116 or the outer enclosure wall internal absorbent liquid. The sprayer 115 and the absorbent liquid sprayer 122 inside the duct are removed by the sprayed absorbent liquid. The method of spraying the absorbent is intuitive and convenient in that it can directly remove residual ammonia, but the removal rate may be somewhat slow. On the other hand, when more air is injected using the air injector 116, the pressure in the inner space of the outer enclosure wall 110 increases, so that the air is forcibly moved more toward the space filled with the absorbent liquid, and the remaining ammonia gas is very effectively absorbed into the absorbent liquid. can be absorbed and eliminated.
상기 흡수액량감소단계에서는, 상기 암모니아제거단계 이후에, 상기 흡수액순환펌프(134B)가 순환시키는 흡수액 양을 감소시킨다. 앞서 설명한 바와 같이 암모니아 누출이 발생하지 않았을 때 다량의 흡수액을 계속 순환시키는 것은 불필요한 에너지 낭비를 초래할 수 있다. 따라서 암모니아 제거가 충분히 이루어졌다면, 다시 평상상태에서와 같이 순환시키는 흡수액 양을 최소화시키도록 상기 흡수액순환펌프(134B)가 조절되는 것이다. 이제 상기 외곽밀폐벽(110) 내부공간의 암모니아 가스가 완전히 제거되었으므로, 상기 암모니아 사용설비(500)가 동작 가능한 상태로 되돌리기만 하면 된다. 따라서 이 과정에서 상기 배수조배수밸브(114v)가 개방되어 상기 외곽밀폐벽(110)에 채워진 흡수액이 배수되는 등의 동작이 이루어질 수 있다.In the absorption liquid amount reduction step, after the ammonia removal step, the absorption liquid amount circulated by the absorption liquid circulation pump 134B is reduced. As described above, continuously circulating a large amount of absorbent liquid when ammonia leakage has not occurred may result in unnecessary energy waste. Therefore, if ammonia is sufficiently removed, the absorbent liquid circulation pump 134B is adjusted to minimize the amount of absorbent liquid to be circulated as in the normal state. Now that the ammonia gas in the inner space of the outer enclosure wall 110 is completely removed, the ammonia using facility 500 only needs to be returned to an operable state. Therefore, in this process, the drain tank drain valve 114v is opened, and an operation such as draining the absorbent liquid filled in the outer sealing wall 110 may be performed.
이처럼 본 발명에 의하면, 암모니아 누출이 발생한다 하더라도 앞서의 누출가스감지단계, 흡수액량증가단계, 암모니아제거단계를 순차적으로 수행함으로써 외부로 방출되는 공기의 독성을 안전한 수준까지 효과적으로 제거할 수 있으며, 또한 그 이후에는 잔존가스제거단계, 흡수액량감소단계가 순차적으로 수행됨으로써 평소의 원래 상태로 매우 원활하게 되돌아갈 수 있다.As described above, according to the present invention, even if ammonia leakage occurs, it is possible to effectively remove the toxicity of the air emitted to the outside to a safe level by sequentially performing the leaked gas detection step, the absorption liquid amount increase step, and the ammonia removal step. After that, the step of removing residual gas and the step of reducing the amount of absorption liquid are sequentially performed, so that it can be returned to the original state very smoothly.

도 13~24를 참조하여, 본 발명의 암모니아 방출방지 및 제거장치 제C실시예(100C) 및 제C실시예의 장치에 의한 방법을 상세히 설명한다. 이하의 설명에서, 기재를 간결하게 하기 위하여 "제C실시예"라는 문구는 생략하나, 도 13~24를 참조하며 [4] 단락에 기재된 모든 "암모니아 방출방지 및 제거장치"는 "암모니아 방출방지 및 제거장치 제C실시예"를 가리키는 것임을 미리 고지한다.Referring to FIGS. 13 and 24, the ammonia emission prevention and removal device of the present invention will be described in detail in the C embodiment (100C) and the method by the device of the C embodiment. In the following description, the phrase "Embodiment C" is omitted for concise description, but referring to FIGS . and removal device C embodiment".
4-1. 제C실시예에 따른 흡수탱크 관련구성4-1. Configuration related to the absorption tank according to the C embodiment
먼저 부연하기로, 앞서의 설명에서 [암모니아 누출 미발생]이라는 것은, 암모니아 누출이 아예 이루어지지 않은 상태를 가리킴은 물론, 암모니아 누출이 아주 미세하게 이루어져서 누출이 발생하기는 하였지만 안전기준 미만인 경우도 포함할 수 있다. 이러한 경우에, 계속 환기가 이루어지는 상황에서 미세한 양의 암모니아라 해도 외부환경으로 그대로 배출되는 것은 장기적으로 볼 때 외부환경에 악영향을 초래할 가능성이 있다. 이러한 문제를 해소할 수 있도록, 상기 덕트(120)에 구비되는 것은 아니되, 공기가 상기 덕트(120)를 통해 환기되는 상태에서 미세하게 누출된 암모니아도 제거할 수 있도록, 공기가 상기 덕트(120)로 가기 전에 통과하게 되는 상기 흡수탱크(130C) 내에 기액접촉층(140)이 구비되는 것이 바람직하다.First of all, to clarify, [no leakage of ammonia] in the above description refers not only to a state in which no ammonia leakage occurs, but also to cases where ammonia leakage is very fine and leaks occur, but is below the safety standard. can do. In this case, even a minute amount of ammonia is discharged to the external environment as it is in a situation where ventilation is continuously performed, which may adversely affect the external environment in the long run. In order to solve this problem, it is not provided in the duct 120, but air is supplied to the duct 120 so that even ammonia leaked in a small amount can be removed while the air is ventilated through the duct 120. ), it is preferable that a gas-liquid contact layer 140 is provided in the absorption tank 130C to pass through.
상기 기액접촉층(140)은, 암모니아 및 공기의 혼합물과 흡수액의 접촉을 증가시키도록 상기 흡수탱크(130C) 내부공간에 분산배치된다. 도 14는 본 발명의 암모니아 방출방지 및 제거장치의 흡수탱크 실시예를 도시한 것으로, 상기 기액접촉층(140)의 다양한 예시를 보여준다. 상기 기액접촉층(140)은, 공기를 타고 이동하는 흡수액 액적이나 암모니아 분자가 원활하게 분산 분포됨으로써 서로간의 접촉을 증가시킬 수 있도록, 도 14(a), (b)에 도시된 바와 같이 상기 흡수탱크(130C) 내에 서로 수직방향으로 이격되며 적어도 하나의 개방부가 형성되는 복수 개의 수평방향의 격막 형태로 형성될 수 있다. 특히 도 14(a)처럼 격막에 약간의 측벽이 형성됨으로써 액체상태의 흡수액이 약간 고여있을 수 있게 할 수도 있다. 또는 도 14(c)에 도시된 바와 같이 상기 흡수탱크(130C) 내에 충진되는 복수 개의 고체충진재 형태로 형성되어, 다공성의 고체충진재에 흡수액이 머금어진 상태에서 이를 통과하여 암모니아 및 공기의 혼합물이 흘러가게 함으로써 접촉을 증가시킬 수 있다.The gas-liquid contact layer 140 is distributed in the inner space of the absorption tank 130C to increase contact between the mixture of ammonia and air and the absorption liquid. 14 shows an embodiment of the absorption tank of the ammonia release prevention and removal device of the present invention, showing various examples of the gas-liquid contact layer 140. The gas-liquid contact layer 140, as shown in FIGS. 14(a) and (b), allows absorption liquid droplets or ammonia molecules moving in the air to be smoothly dispersed and distributed to increase contact with each other. It may be formed in the form of a plurality of horizontal diaphragms spaced apart from each other in the vertical direction in the tank 130C and having at least one opening. Particularly, as shown in FIG. 14(a), some sidewalls are formed on the diaphragm so that the absorbent liquid in a liquid state can be slightly pooled. Alternatively, as shown in FIG. 14(c), it is formed in the form of a plurality of solid fillers filled in the absorption tank 130C, and a mixture of ammonia and air flows through the porous solid filler in a state where the absorption liquid is contained. You can increase contact by letting go.
이후 보다 상세히 설명되겠지만, 본 발명에서는 본격적으로 암모니아 누출이 발생될 경우, 상기 흡수탱크(130C) 내에 구비되는 이젝터(135C)를 이용하여 암모니아를 흡수액과 적극적으로 접촉시켜 제거한다. 따라서 상기 이젝터(135C)는 도 13에 도시된 바와 같이 상기 흡수탱크(130C)의 중간쯤에 구비되어 있도록 하는 것이 적절하다. 한편 상기 기액접촉층(140)은 상기 이젝터(135C)가 작동하지 않는 시점(즉 암모니아 누출 미발생 시)에도 작동하지만, 상기 이젝터(135C)가 작동하는 시점(즉 암모니아 누출 발생 시)에도 공기순환 구동에 따라 상기 이젝터(135C)를 통하지 않고 상기 흡수탱크(130C)로 유입된 암모니아를 제거하기 위해 작동하게 된다. 이러한 점을 고려하여, 상기 기액접촉층(140)은 상기 이젝터(135C)보다 상기 환기배출로(112)에 보다 가까운 위치, 즉 상기 이젝터(135C) 하방에 배치되는 것이 바람직하다.As will be described later in detail, in the present invention, when ammonia leakage occurs in earnest, the ammonia is removed by actively contacting the absorption liquid using the ejector 135C provided in the absorption tank 130C. Therefore, it is appropriate that the ejector 135C is provided in the middle of the absorption tank 130C as shown in FIG. 13 . Meanwhile, the gas-liquid contact layer 140 operates even when the ejector 135C does not operate (ie, when ammonia leak does not occur), but air circulation occurs even when the ejector 135C operates (ie, when ammonia leak occurs). When driven, it operates to remove ammonia introduced into the absorption tank 130C without passing through the ejector 135C. Considering this point, it is preferable that the gas-liquid contact layer 140 be disposed closer to the ventilation discharge path 112 than to the ejector 135C, that is, below the ejector 135C.
더불어 상기 기액접촉층(140)이 충분히 암모니아를 다 제거하지 못할 수도 있으며, 이러한 경우를 대비하여 보조기액접촉층(145)이 더 구비될 수도 있다. 도 21은 본 발명의 암모니아 방출방지 및 제거장치 제2응용구성로서, 상기 보조기액접촉층(145)이 더 구비된 응용구성을 도시하고 있다. 상기 보조기액접촉층(145)은 상기 기액접촉층(140)과 유사하게, 상기 암모니아 및 공기의 혼합물과 흡수액의 접촉을 증가시키도록 상기 흡수탱크(130C) 내에 분산배치되되, 상기 기액접촉층(140)에서 제거되지 못한 암모니아를 보조적으로 제거할 수 있도록 상기 이젝터(135C) 상방에 배치되는 것이 바람직하다.In addition, the gas-liquid contact layer 140 may not sufficiently remove all ammonia, and an auxiliary gas-liquid contact layer 145 may be further provided to prepare for this case. 21 shows a second application configuration of the ammonia release prevention and removal device of the present invention, further comprising the auxiliary gas-liquid contact layer 145. Similar to the gas-liquid contact layer 140, the auxiliary gas-liquid contact layer 145 is distributed in the absorption tank 130C to increase contact between the mixture of ammonia and air and the absorption liquid, and the gas-liquid contact layer ( It is preferable to be disposed above the ejector 135C to assist in removing ammonia that could not be removed in 140).
상기 흡수탱크(130C) 및 이에 구비되는 장치들에 대하여 설명한다.The absorption tank 130C and devices provided thereto will be described.
상기 흡수탱크(130C)는 암모니아 흡수액을 수용하는 역할을 하며, 상기 암모니아 사용설비(500)에서 암모니아 누출 발생 시 암모니아가 유통되는 공간으로 흡수액을 공급하여 암모니아를 최대한 흡수시켜 공기로부터 제거할 수 있도록 한다. 앞서 간략히 설명한 바와 같이, 본 발명에서는 암모니아 누출 발생 시 상기 외부밀폐벽(110) 및 상기 흡수탱크(130C) 공간이 외부환경과 완전히 격리되도록 하고, 공기가 상기 외부밀폐벽(110) 및 상기 흡수탱크(130C)를 순환하면서 상기 흡수탱크(130C)에서 암모니아가 제거되도록 한다. 보다 구체적으로는, 상기 외곽밀폐벽(110) 내부공간에서 암모니아 누출 발생 시, 상기 환기유입로(111) 및 상기 공기배기로(137C)가 폐쇄되어 상기 외곽밀폐벽(110) 및 상기 흡수탱크(130C) 내부공간이 외부와 격리되도록 형성되어, 상기 공기주입기(116)를 통해 상기 외곽밀폐벽(110) 내부공간으로 주입된 공기가 암모니아와 혼합되어 상기 환기배출로(112)로 배출되게 한다. 이 때 흡수액과 상기 환기배출로(112)를 통해 배출된 암모니아 및 공기의 혼합물이 상기 이젝터(135C)로 각각 공급되어 혼합되어 분사되는 과정에서 암모니아가 흡수액에 용해되어 제거된다. 이후 상기 이젝터(135C)를 통과하면서 암모니아가 제거되어 정제된 공기가 상기 공기순환로(133C)를 통해 상기 외곽밀폐벽(110)으로 복귀되어 순환되게 된다. 이러한 방식으로 운전되는 것을 본 발명에서는 가스흡수모드 운전이라 칭한다. 요약하면, 본 발명에서 상기 암모니아 방출방지 및 제거장치(100C)는, 상기 외곽밀폐벽가스감지기(113) 또는 상기 흡수탱크가스감지기(134C)에서 감지된 암모니아 누출량이 기결정된 감지기준 미만이면 암모니아 누출 미발생으로 판단하여 정상운전모드로 운전되고, 상기 감지기준 이상이면 암모니아 누출 발생으로 판단하여 가스흡수모드로 운전되는 것이다.The absorption tank (130C) serves to accommodate the ammonia absorption liquid, and when ammonia leaks in the ammonia using facility 500, the absorption liquid is supplied to the space where ammonia is distributed so that the ammonia can be maximally absorbed and removed from the air. . As briefly described above, in the present invention, when ammonia leakage occurs, the space of the outer sealing wall 110 and the absorption tank 130C is completely isolated from the external environment, and air is supplied to the outer sealing wall 110 and the absorption tank. While circulating through (130C), ammonia is removed from the absorption tank (130C). More specifically, when ammonia leaks in the inner space of the outer enclosure wall 110, the ventilation inlet passage 111 and the air exhaust passage 137C are closed so that the outer enclosure wall 110 and the absorption tank ( 130C) The inner space is formed to be isolated from the outside, so that the air injected into the inner space of the outer enclosure wall 110 through the air injector 116 is mixed with ammonia and discharged to the ventilation outlet 112. At this time, the mixture of the absorbent liquid, ammonia and air discharged through the ventilation outlet 112 is supplied to the ejector 135C, mixed, and sprayed, whereby the ammonia is dissolved in the absorbent liquid and removed. Thereafter, the ammonia is removed while passing through the ejector 135C, and the purified air returns to the outer enclosure wall 110 through the air circulation path 133C and is circulated. Operation in this way is referred to as gas absorption mode operation in the present invention. In summary, in the present invention, the ammonia release prevention and removal device (100C) leaks ammonia if the ammonia leak amount detected by the outer enclosure wall gas detector 113 or the absorption tank gas detector 134C is less than a predetermined detection standard. It is determined that no occurrence occurs and is operated in the normal operation mode, and if the detection standard is higher than the detection standard, it is determined that ammonia leak occurs and is operated in the gas absorption mode.
상기 흡수탱크(130C)에는, 기본적으로 탱크연통로(131C), 이젝터통로(132C), 공기순환로(133C), 흡수탱크가스감지기(134C), 상기 이젝터(135C), 흡수액순환펌프(136C)가 구비되며, 흡수액을 보충해주기 위한 흡수액주입기(138C), 암모니아와 흡수액의 접촉을 증가시키기 위한 흡수액분배기(139C)가 더 구비될 수 있다.In the absorption tank 130C, basically, a tank communication passage 131C, an ejector passage 132C, an air circulation passage 133C, an absorption tank gas detector 134C, the ejector 135C, and an absorbent liquid circulation pump 136C are provided. An absorbent liquid injector 138C for replenishing the absorbent liquid and an absorbent liquid distributor 139C for increasing contact between ammonia and the absorbent liquid may be further provided.
상기 이젝터(135C)는, 상기 흡수탱크(130C) 내에 구비되어 공기 및 흡수액을 유입받아 혼합하여 분사하는 역할을 한다. 도 15는 본 발명의 암모니아 방출방지 및 제거장치의 이젝터 실시예를 도시한 것이다. 도 15에 도시된 바와 같이, 상기 이젝터(135C)는 2개의 유입구와 1개의 배출구를 가지며, 유로면적이 급격하게 변하는 구간이 존재한다. 각각의 유입구로는 서로 다른 유체가 유입되며, 유로면적이 급격하게 좁아짐에 따라 유입된 유체들은 빠른 유속으로 흘러가게 된다. 이렇게 빠르게 진행된 각각의 유체는 이제 유로면적이 급격하게 넓어짐에 따라 매우 활발하게 서로 혼합되면서 흘러가며, 배출구로는 이렇게 잘 혼합된 유체들의 혼합물이 배출되게 된다.The ejector 135C is provided in the absorption tank 130C and serves to receive air and absorption liquid, mix them, and eject them. 15 shows an ejector embodiment of the ammonia release prevention and removal device of the present invention. As shown in FIG. 15, the ejector 135C has two inlets and one outlet, and there is a section where the passage area changes rapidly. Different fluids are introduced into each inlet, and as the passage area is rapidly narrowed, the introduced fluids flow at a high flow rate. Each of the fluids that have progressed so rapidly now flows while being mixed with each other very actively as the passage area is rapidly widened, and a mixture of these well-mixed fluids is discharged through the outlet.
상기 탱크연통로(131C), 상기 이젝터통로(132C), 상기 공기순환로(133C)는, 암모니아 누출 발생 시 공기가 순환되는 경로를 형성한다. 각각 설명하자면, 상기 탱크연통로(131C)는 상기 흡수탱크(130C) 및 상기 환기배출로(112)를 연결하며 탱크연통로밸브(131Cv)에 의해 개폐가능하게 형성된다. 상기 이젝터통로(132C)는 상기 이젝터(135C) 및 상기 환기배출로(112)를 연결하며 이젝터통로밸브(132Cv)에 의해 개폐가능하게 형성된다. 상기 공기순환로(133C)는 상기 흡수탱크(130C) 상단 및 상기 외곽밀폐벽(110) 상단을 연결하며 공기순환로밸브(133Cv)에 의해 개폐가능하게 형성되어 상기 흡수탱크(130C) 내 공기를 상기 외곽밀폐벽(110) 내로 순환시킨다.The tank communication passage 131C, the ejector passage 132C, and the air circulation passage 133C form a passage through which air is circulated when ammonia leakage occurs. To explain each, the tank communication passage 131C connects the absorption tank 130C and the ventilation discharge passage 112 and is formed to be opened and closed by a tank communication passage valve 131Cv. The ejector passage 132C connects the ejector 135C and the ventilation discharge passage 112 and is formed to be opened and closed by an ejector passage valve 132Cv. The air circulation passage 133C connects the upper end of the absorption tank 130C and the upper end of the outer enclosure wall 110 and is formed to be opened and closed by an air circulation passage valve 133Cv so that air in the absorption tank 130C is transported to the outer enclosure. It is circulated into the sealing wall 110.
상기 흡수탱크가스감지기(134C)는, 상기 흡수탱크(130C)에 구비되어 상기 흡수탱크(130C) 내 수용된 흡수액 상측공간의 암모니아 농도 또는 흡수액의 pH를 측정하는 역할을 한다. 도 13에서는 상기 흡수탱크가스감지기(134C)가 흡수액 바깥에 구비되어 침수되지 않도록 하는 형태로 도시되어 있으나 반드시 이렇게만 되어야 하는 것은 아니고, 흡수액의 pH를 측정하여 가스를 감지하는 경우 흡수액 수중에 구비되도록 할 수도 있는 등 감지기의 가스감지 원리에 따라 구비위치는 다양하게 달라질 수 있다. 뿐만 아니라 상기 흡수탱크가스감지기(134C)가 단일 개만 구비될 필요는 없으며, 암모니아 제거율 모니터링을 위해, 복수 개의 상기 흡수탱크가스감지기(134C)가 서로 다른 높이로 구비되도록 할 수도 있다.The absorption tank gas detector 134C is provided in the absorption tank 130C and serves to measure the ammonia concentration in the upper space of the absorption liquid contained in the absorption tank 130C or the pH of the absorption liquid. In FIG. 13, the absorption tank gas detector 134C is provided outside the absorption liquid to prevent submersion, but it does not have to be this way, so that it is provided in the absorption liquid when detecting gas by measuring the pH of the absorption liquid. Depending on the gas detection principle of the detector, the position of the detector may be variously changed. In addition, it is not necessary to have only one absorption tank gas detector 134C, and a plurality of absorption tank gas detectors 134C may be provided at different heights to monitor the ammonia removal rate.
상기 흡수액순환펌프(136C)는, 상기 흡수탱크(130C) 하측에 수용된 흡수액을 끌어올리는 경로인 흡수액순환유로(136Cp)에 구비되어 흡수액을 펌핑하는 역할을 한다. 상기 흡수액순환유로(136Cp)에는 펌프-이젝터유로(136Ca) 및 펌프-탱크유로(136Cb)가 연결될 수 있다. 상기 흡수액순환펌프(136C)에 의하여 펌핑되어 상기 흡수액순환유로(136Cp)로 끌어올려진 흡수액은, 정상운전모드에서는 펌프-탱크유로(136Cb)를 통해 상기 흡수탱크(130C) 상측에서 다시 제공되어 순환될 수 있다. 반면 가스흡수모드에서는, 이렇게 끌어올려진 흡수액이 펌프-이젝터유로(136Ca)를 통해 상기 이젝터(135C)로 제공됨으로써 암모니아를 제거하는 데에 사용되게 된다. 더불어 상기 흡수액순환유로(136Cp)에는, 상기 흡수탱크(130C) 하측에 수용되며 암모니아를 흡수한 흡수액을 외부에서 처리하도록 배출하는 펌프-배출유로(136Cc)가 더 연결될 수 있다. The absorbent liquid circulation pump 136C is provided in the absorbent liquid circulation passage 136Cp, which is a path for raising the absorbent liquid accommodated in the lower side of the absorption tank 130C, and serves to pump the absorbent liquid. A pump-ejector passage 136Ca and a pump-tank passage 136Cb may be connected to the absorption liquid circulation passage 136Cp. The absorbent liquid pumped by the absorbent liquid circulation pump 136C and lifted up to the absorbent liquid circulation passage 136Cp is provided again from the upper side of the absorption tank 130C through the pump-tank passage 136Cb in the normal operation mode and is circulated. It can be. On the other hand, in the gas absorption mode, the pump-ejector liquid is provided to the ejector 135C through the pump-ejector passage 136Ca, so that it is used to remove ammonia. In addition, a pump-discharge passage 136Cc accommodated in the lower side of the absorption tank 130C and discharging the absorption liquid that has absorbed ammonia to be treated externally may be further connected to the absorption liquid circulation path 136Cp.
이 때 상기 이젝터(135C)로 제공되는 흡수액이 계속 순환되기 때문에, 시간이 지날수록 암모니아를 이미 많이 흡수하게 되어 흡수성능이 다소 떨어질 수 있다. 따라서 암모니아를 흡수하지 않은 새로운 흡수액이 상기 이젝터(135C)로 별도 공급되도록 할 수 있는데, 도 22가 바로 이러한 구성을 보여주는 제3응용구성이다. 도 22의 제3응용구성에서는, 상기 펌프-이젝터유로(136Ca)가 상기 흡수액순환유로(136Cp)가 아닌 상기 흡수액주입기(138C)와 연결되어, 암모니아를 흡수한 적이 없는 새로운 흡수액을 제공받을 수 있게 형성된다. 즉 이 경우 상기 흡수액주입기(138C)에서 주입되는 흡수액 일부가 우회되어 상기 펌프-이젝터유로(136Ca)를 통해 상기 이젝터(135C)로 제공되는 것이다. 물론 이렇게 하면 흡수성능이 향상되는 것은 자명하나 다소 유로구성이 복잡해질 수 있다는 약점이 있다. 따라서 흡수성능 향상 및 유로구성 복잡성 측면을 모두 고려하여, 도 13 또는 도 22의 구성 중 적절하게 하나를 선택하거나 또는 둘을 합친 구성이 적절하게 선택적으로 도입될 수 있다.At this time, since the absorbent liquid supplied to the ejector 135C is continuously circulated, a large amount of ammonia is already absorbed as time passes, and the absorption performance may be somewhat deteriorated. Therefore, a new absorption liquid that does not absorb ammonia can be separately supplied to the ejector 135C, and FIG. 22 is a third application configuration showing such a configuration. 22, the pump-ejector flow path 136Ca is connected to the absorbent liquid injector 138C instead of the absorbent liquid circulation path 136Cp, so that a new absorbent liquid that has not absorbed ammonia can be provided. is formed That is, in this case, a portion of the absorbent liquid injected from the absorbent liquid injector 138C is bypassed and supplied to the ejector 135C through the pump-ejector passage 136Ca. Of course, it is obvious that the absorption performance is improved by doing this, but there is a weakness that the flow path configuration can be somewhat complicated. Therefore, in consideration of both the improvement in absorption performance and the complexity of the passage configuration, either one of the configurations of FIG. 13 or 22 or a combination of the two may be appropriately and selectively introduced.
상기 공기배기로(137C)는, 암모니아 누출 미발생 시 공기가 환기되는 경로를 형성하는 것으로, 상기 외곽밀폐벽(110) 내부공간과 상기 덕트(120)를 연결한다. 보다 구체적으로, 상기 공기배기로(137C)는 상기 흡수탱크(130C) 상단 및 상기 덕트(120)를 연결하는 통로로서, 상기 흡수탱크(130C) 내 공기를 공기배기로송풍기(137Cf)에 의해 강제송풍하여 상기 덕트(120)를 통해 배출시키도록 형성된다. 또한 정상운전모드 및 가스흡수모드 시 개폐될 수 있도록, 공기배기로밸브(137Cv)에 의해 개폐가능하게 형성된다.The air exhaust passage 137C forms a path through which air is ventilated when ammonia does not leak, and connects the inner space of the outer enclosure wall 110 and the duct 120 . More specifically, the air exhaust passage 137C is a passage connecting the upper end of the absorption tank 130C and the duct 120, and the air in the absorption tank 130C is forced by the air exhaust blower 137Cf. It is formed to blow air and discharge it through the duct 120. In addition, it is formed to be opened and closed by the air exhaust valve 137Cv so that it can be opened and closed during the normal operation mode and the gas absorption mode.
상기 흡수액분배기(139C)는, 상기 흡수액주입기(138C)에 인접하게 구비된 수평방향의 격막 형태로 형성되며 복수 개의 개방부가 분포 형성된다. 도 13로 유추할 수 있듯이, 흡수액은 상기 흡수액주입기(138C) 또는 상기 펌프-탱크유로(136Cb)를 통해 상기 흡수탱크(130C) 상단에서 제공되는데, 이 때 상기 흡수액분배기(139C)가 흡수액이 제공되는 위치 하방에 구비됨으로써, 도 14(a), (b) 실시예의 상기 기액접촉층(140)과 마찬가지 원리로, 공기를 타고 이동하는 흡수액 액적이나 암모니아 분자가 원활하게 분산 분포되게 함으로써 암모니아 및 공기의 혼합물과 흡수액의 접촉을 원활하게 증가시킬 수 있다.The absorbent liquid distributor 139C is formed in the form of a horizontal diaphragm provided adjacent to the absorbent liquid injector 138C, and a plurality of openings are distributed. As can be inferred from FIG. 13, the absorbent liquid is provided from the top of the absorption tank 130C through the absorbent liquid injector 138C or the pump-tank flow path 136Cb. At this time, the absorbent liquid distributor 139C provides the absorbent liquid. 14 (a), (b) by being provided below the position, on the same principle as the gas-liquid contact layer 140 of the embodiment of FIG. It is possible to smoothly increase the contact between the mixture of and the absorption liquid.
더불어 도 13에서는 하나의 상기 흡수탱크(130C)에 하나의 상기 환기배출로(112)가 연결되는 것으로 도시되어 있으나, 이로써 본 발명이 한정되는 것은 아니다. 즉 복수 개의 암모니아 사용설비(500)를 하나의 상기 흡수탱크(130C)로 관리하도록 할 수 있는데, 이러한 경우 하나의 상기 흡수탱크(130C)에 복수 개의 상기 외곽밀폐벽(110)이 연결되도록 할 수 있다. 특히 상기 외곽밀폐벽(110) 중 적어도 하나는, 암모니아 사용설비(500)를 직접 수용하는 대신 흡수액을 수용하며, 외부 타 시스템에서 배출된 암모니아가 유입되어 흡수액에 의해 암모니아가 제거되도록 형성된다. 도 23이 바로 이러한 구성을 나타내는 제4응용구성이다.In addition, although FIG. 13 shows that one ventilation outlet 112 is connected to one absorption tank 130C, the present invention is not limited thereto. That is, a plurality of ammonia using facilities 500 can be managed by one absorption tank 130C. In this case, a plurality of outer enclosure walls 110 can be connected to one absorption tank 130C. there is. In particular, at least one of the outer enclosure walls 110 accommodates the absorption liquid instead of directly accommodating the ammonia using facility 500, and is formed so that ammonia discharged from another external system flows in and the ammonia is removed by the absorption liquid. 23 is a fourth application configuration showing such a configuration.
이러한 경우 상기 외곽밀폐벽(110) 내에는 흡수액만이 수용되므로 보조적인 흡수탱크 개념으로 볼 수 있다. 따라서 이러한 경우 상기 외곽밀폐벽(110)에는, 암모니아 및 공기의 혼합물과 흡수액의 접촉을 증가시키도록 상기 외곽밀폐벽(110) 내부에 접촉증가구조물이 구비되도록 하는 것이 바람직하다. 상기 접촉증가구조물 형태의 여러 실시예가 도 24에 도시되어 있는데, 상기 접촉증가구조물은 먼저 도 24(a)에 도시된 바와 같이 상기 외곽밀폐벽(110)으로 흡수액이 유입되는 측에 인접하게 구비된 수평방향의 격막 형태로 형성되며 복수 개의 개방부가 분포 형성되는 분배기 형태일 수도 있다. 또는 도 24(b), (c) ,(d) 도시된 바와 같이 상기 외곽밀폐벽(110) 내에 서로 수직방향으로 이격되며 적어도 하나의 개방부가 형성되는 복수 개의 수평방향의 격막 형태일 수도 있다. 또는 도 24(e)에 도시된 바와 같이 상기 외곽밀폐벽(110) 내에 충진되는 복수 개의 고체충진재 형태일 수도 있다. 즉 상기 접촉증가구조물, 상술한 여러 형태들 중 선택되는 적어도 하나로 적절히 선택될 수 있다.In this case, since only the absorption liquid is accommodated in the outer enclosure wall 110, it can be regarded as an auxiliary absorption tank concept. Therefore, in this case, it is preferable to provide a contact increasing structure inside the outer wall 110 to increase the contact between the mixture of ammonia and air and the absorption liquid. Various embodiments of the form of the contact increasing structure are shown in FIG. 24, and the contact increasing structure is first provided adjacent to the side where the absorbent liquid flows into the outer sealing wall 110, as shown in FIG. 24(a). It is formed in the form of a diaphragm in a horizontal direction and may be in the form of a distributor in which a plurality of openings are distributed. Alternatively, as shown in FIGS. 24(b), (c) and (d), it may be in the form of a plurality of horizontally spaced diaphragms spaced apart from each other in the vertical direction within the outer enclosure wall 110 and having at least one opening formed therein. Alternatively, as shown in FIG. 24(e), it may be in the form of a plurality of solid fillers filled in the outer enclosure wall 110. That is, the contact increasing structure may be appropriately selected as at least one selected from among the various forms described above.
4-2. 제C실시예에 따른 본 발명의 암모니아 방출방지 및 제거방법4-2. Method for preventing and removing ammonia of the present invention according to Example C
이하에서, 상술한 바와 같은 본 발명의 암모니아 방출방지 및 제거장치(100C)를 사용하는 암모니아 방출방지 및 제거방법에 대하여 단계적으로 상세히 설명한다. 본 발명의 암모니아 방출방지 및 제거방법은, 기본적으로 앞서 설명한 바와 같이, 암모니아 누출 미발생 시에는 상기 외곽밀폐벽(110) 내부공간이 외부환경과 연통되어 자유로운 환기가 이루어지도록 하되, 암모니아 누출 발생 시에는 상기 외곽밀폐벽(110) 내부공간이 외부환경과 완전 격리된 상태에서 공기가 상기 외곽밀폐벽(110) 및 상기 흡수탱크(130C)를 순환하여 흐르면서 지속적으로 암모니아가 제거되도록 이루어진다. 이에 암모니아 누출 미발생 시의 동작모드를 "정상운전모드", 암모니아 누출 발생 시의 동작모드를 "가스흡수모드"라 한다. 한편 가스흡수모드에서의 암모니아 누출량 예상치보다 더 많이 누출이 발생하는 특수한 경우에 한정적으로 이루어지는 동작모드인 "추가흡수모드"가 더 있을 수 있다. 또한 가스흡수모드에서 충분히 암모니아를 흡수하여 모두 제거한 뒤에는 다시 평상시의 정상운전모드로 되돌아와야 하는데, 이를 위한 여러 준비단계들이 수행되는 동작모드인 "복구운전모드"가 있을 수 있다. 이하에서 각각의 모드에 대하여 구체적으로 상세히 설명한다.Hereinafter, the ammonia emission prevention and removal method using the ammonia emission prevention and removal device 100C of the present invention as described above will be described in detail step by step. As described above, basically, in the method for preventing and removing ammonia of the present invention, when ammonia leakage does not occur, the inner space of the outer enclosure wall 110 communicates with the external environment to allow free ventilation, but when ammonia leakage occurs In a state in which the inner space of the outer wall 110 is completely isolated from the external environment, ammonia is continuously removed while air circulates through the outer wall 110 and the absorption tank 130C. Accordingly, an operation mode when no ammonia leakage occurs is referred to as a "normal operation mode", and an operation mode when ammonia leakage occurs is referred to as a "gas absorption mode". On the other hand, there may be an "additional absorption mode" which is an operation mode limited to a special case in which leakage of ammonia is greater than the estimated leakage amount of ammonia in the gas absorption mode. In addition, after sufficiently absorbing ammonia in the gas absorption mode and removing all of it, it is necessary to return to the normal operation mode again. Hereinafter, each mode will be described in detail in detail.
도 16은 본 발명의 암모니아 방출방지 및 제거장치의 정상운전모드를 설명하기 위한 도면이다. 도 16을 비롯하여 이하의 도 17 내지 도 19에서, 이해를 보다 쉽게 하기 위하여 각 모드에서 동작하지 않는 장치들은 흐리게 표시하였다. 앞서 설명한 바와 같이 암모니아 누출 미발생 시에 정상운전모드 운전이 수행되게 되는데, 본 발명에서 "암모니아 누출 미발생"이란 "상기 외곽밀폐벽가스감지기(113) 또는 상기 흡수탱크가스감지기(134C)에 의해 누출된 암모니아 가스가 기결정된 감지기준 미만으로 감지되는 것"으로 정의된다. 여기에서 "감지기준"은 일반적으로 알려진 안전기준인 25ppm 수준으로 결정될 수도 있고, 보다 안전성을 높이기 위하여 이보다 낮은 수준으로 결정될 수도 있는 등, 사용자의 필요나 목적 등에 따라 적절하게 결정되면 된다. 상기 정상운전모드 운전은, 공기유입단계, 공기환기단계를 포함하며, 여기에 더불어 흡수액순환단계, 미량가스제거단계를 더 포함할 수 있다.16 is a view for explaining a normal operation mode of the ammonia emission prevention and removal device of the present invention. In FIGS. 17 to 19 including FIG. 16 , devices that do not operate in each mode are shaded for easier understanding. As described above, normal operation mode operation is performed when ammonia leakage does not occur. A leaked ammonia gas is detected below a predetermined detection criterion." Here, the "detection standard" may be determined at a level of 25 ppm, which is a generally known safety standard, or may be determined at a lower level to increase safety, and may be appropriately determined according to the user's needs or purposes. The operation in the normal operation mode includes an air introduction step and an air ventilation step, and may further include an absorbent liquid circulation step and a trace gas removal step.
상기 공기유입단계에서는, 상기 환기유입로(111)를 통해 상기 외곽밀폐벽(110) 내부공간으로 공기가 유입된다. 즉 이 단계에서 상기 환기유입로밸브(111v)는 개방된 상태이며, 상기 외곽밀폐벽(110)은 외부환경과 격리되지 않은 상태인 것이다.In the air introduction step, air is introduced into the inner space of the outer enclosure wall 110 through the ventilation inlet 111 . That is, at this stage, the ventilation inlet valve 111v is open, and the outer enclosure wall 110 is not isolated from the external environment.
상기 공기환기단계에서는, 유입된 공기가 상기 환기배출로(112), 상기 흡수탱크(130C), 상기 공기배기로(137C)를 순차적으로 통과하여 상기 덕트(120)를 통해 외부로 배출됨으로써 환기된다. 도 16을 참조할 때, 상기 환기유입로(111)에서부터 상기 덕트(120)까지 연결하는 유로들에 구비된 밸브들이 모두 개방됨으로써 이러한 동작을 실현할 수 있다. 더불어 이 경우, 상기 환기유입로(111)로 공기를 유입시키는 구동력은, 상기 공기배기로(137C) 상에 구비된 상기 공기배기로송풍기(137Cf)에 의해 인가된다. 즉 상기 공기배기로송풍기(137Cf)가 강제송풍을 함으로써 공기가 상기 덕트(120)로 빨려나가는데, 이렇게 공기가 빨려나감으로써 상기 흡수탱크(130C) 및 이와 연통된 상기 외곽밀폐벽(110) 내부공간의 압력이 낮아지면 자연스럽게 열려있는 상기 환기유입로(111)로 외부의 공기가 빨려들어오게 되는 것이다.In the air ventilation step, the introduced air sequentially passes through the ventilation discharge path 112, the absorption tank 130C, and the air exhaust path 137C, and is discharged to the outside through the duct 120 to be ventilated. . Referring to FIG. 16 , this operation can be realized by opening all the valves provided in the passages connecting the ventilation inflow passage 111 to the duct 120 . In addition, in this case, the driving force for introducing air into the ventilation inlet passage 111 is applied by the air exhaust passage blower 137Cf provided on the air exhaust passage 137C. That is, air is sucked into the duct 120 by forcible blowing by the blower 137Cf through the air exhaust. As the air is sucked out, the absorption tank 130C and the inner space of the outer enclosure wall 110 communicating therewith When the pressure of is lowered, the outside air is sucked into the ventilation inlet 111 that is naturally open.
상기 흡수액순환단계 및 상기 미량가스제거단계는, 상기 공기환기단계에서 공기가 상기 흡수탱크(130C)를 통과하는 과정과 병행하여 이루어진다. 앞서 설명한 바와 같이 본 발명에서 "암모니아 누출 미발생"이라는 것은 누출량이 기결정된 "감지기준" 미만인 경우를 말하는 것으로, 즉 엄밀하게는 "암모니아 누출 미발생" 시에도 미량의 암모니아가 환기되는 공기에 섞여있을 수 있다. 물론 안전기준보다 낮은 농도이기 때문에 당장 큰 문제는 없겠으나, 미량의 암모니아라 하더라도 지속적으로 외부환경에 배출될 경우 장기적으로 볼 때 환경에 악영향을 끼칠 수도 있는 문제가 있다. 이러한 문제를 방지하기 위하여 수행되는 것이 바로 상기 흡수액순환단계 및 상기 미량가스제거단계이다.The absorption liquid circulation step and the trace gas removal step are performed in parallel with the process of passing air through the absorption tank 130C in the air ventilation step. As described above, in the present invention, "ammonia leakage does not occur" refers to a case where the leakage amount is less than a predetermined "detection standard", that is, even when strictly "ammonia leakage does not occur", a small amount of ammonia is mixed with the ventilated air There may be. Of course, since the concentration is lower than the safety standard, there is no immediate problem, but even a small amount of ammonia may adversely affect the environment in the long run if it is continuously discharged to the external environment. In order to prevent this problem, the absorption liquid circulation step and the trace gas removal step are performed.
상기 흡수액순환단계는 암모니아 제거를 위한 흡수액을 상기 흡수탱크(130C) 내부공간 전체에 걸쳐 잘 분산시킴으로써 흡수액 및 암모니아 간의 접촉을 증가시켜주는 단계이다. 보다 구체적으로 상기 흡수액순환단계에서는, 상기 흡수액순환펌프(136C)에 의하여 상기 흡수탱크(130C) 하측에 수용된 흡수액이 상기 흡수액순환유로(136Cp)를 따라 끌어올려지고, 흡수액이 상기 펌프-탱크유로(136Cb)를 통해 상기 흡수탱크(130C) 상측에서 다시 제공되어 순환된다.The absorbent liquid circulation step is a step of increasing the contact between the absorbent liquid and ammonia by well distributing the absorbent liquid for removing ammonia throughout the inner space of the absorption tank 130C. More specifically, in the absorbent liquid circulation step, the absorbent liquid accommodated in the lower side of the absorption tank 130C by the absorbent liquid circulation pump 136C is pulled up along the absorbent liquid circulation passage 136Cp, and the absorbent liquid flows through the pump-tank passage ( 136Cb) is supplied again from the upper side of the absorption tank 130C and circulated.
상기 미량가스제거단계는 상기 흡수액순환단계와 병행하여 이루어지는 것으로서, 상기 공기환기단계에서 공기가 상기 흡수탱크(130C)를 통과하는 과정에서, 상기 흡수탱크(130C) 상측에서 제공되는 흡수액에 의해 공기 내에 포함된 미량의 암모니아가 제거된다. 이 때 상기 흡수탱크(130C)에 상기 기액접촉층(140)이 구비되는 경우, 상기 흡수탱크(130C) 상측에서 뿌려진 흡수액이 그냥 떨어져내리는 것이 아니라 상기 기액접촉층(140)에 머금어져 상기 흡수탱크(130C) 내부공간 중간에 얼마간 잔존될 수 있다. 이 경우 상기 미량가스제거단계는, 상기 기액접촉층(140)에 잔존된 흡수액에 의해 공기 내에 포함된 미량의 암모니아가 더 제거될 수 있다.The trace gas removal step is performed in parallel with the absorption liquid circulation step, and in the process of air passing through the absorption tank 130C in the air ventilation step, the absorbent liquid provided from the upper side of the absorption tank 130C enters the air. Trace amounts of ammonia are removed. At this time, when the gas-liquid contact layer 140 is provided in the absorption tank 130C, the absorption liquid sprayed from the upper side of the absorption tank 130C does not just fall down, but is contained in the gas-liquid contact layer 140 and is absorbed into the absorption tank 130C. (130C) May remain for some time in the middle of the inner space. In this case, in the step of removing the trace gas, trace amounts of ammonia contained in the air may be further removed by the absorption liquid remaining in the gas-liquid contact layer 140 .
한편 상술한 바와 같이 안전성을 최대로 고려한다면 상기 흡수액순환단계 및 상기 미량가스제거단계가 수행되는 것이 올바르겠으나, 실질적으로 흡수액을 계속 순환시키기 위해서는 상당한 전력이 소모되는 손해가 발생하는 것이 사실이고, 미량의 암모니아가 누출된다 해도 자연 상태의 암모니아 농도와 크게 다르지 않으므로 환경오염 문제 자체는 미미하다 할 수 있다. 따라서 전력소모 문제를 보다 더 중요하게 고려한다면, 앞서 설명한 도 20의 제1응용구성을 적용하여 공기가 상기 흡수탱크(130C)를 거치지 않고 바로 상기 덕트(120)를 통해 빠져나가게 해도 된다. 즉 도 20의 제1응용구성에서처럼 상기 암모니아 방출방지 및 제거장치(100C)가 상기 덕트연통로(121)를 포함할 경우, 상기 공기환기단계는, 유입된 공기가 상기 환기배출로(112), 상기 덕트연통로(121)를 순차적으로 통과하여 상기 덕트(120)를 통해 외부로 배출됨으로써 환기되도록 이루어질 수 있다. 이 경우 상기 환기유입로(111)로 공기를 유입시키는 구동력은, 상기 덕트연통로(121) 상에 구비된 상기 덕트연통로송풍기(121f)에 의해 인가된다.On the other hand, if safety is considered as the maximum as described above, it would be correct to perform the absorption liquid circulation step and the trace gas removal step. Even if ammonia leaks, it is not very different from the natural ammonia concentration, so the environmental pollution problem itself can be said to be insignificant. Therefore, if the power consumption problem is considered more important, the air may escape directly through the duct 120 without passing through the absorption tank 130C by applying the first application configuration of FIG. 20 described above. That is, when the ammonia release prevention and removal device 100C includes the duct communication passage 121 as in the first application configuration of FIG. Ventilation may be achieved by sequentially passing through the duct communication passage 121 and being discharged to the outside through the duct 120 . In this case, the driving force for introducing air into the ventilation inlet 111 is applied by the duct communication passage blower 121f provided on the duct communication passage 121 .
도 17은 본 발명의 암모니아 방출방지 및 제거장치의 가스흡수모드를 설명하기 위한 도면이다. 앞서 설명한 바와 같이 암모니아 누출 발생 시에 가스흡수모드 운전이 수행되게 되는데, 본 발명에서 "암모니아 누출 발생"이란 "상기 외곽밀폐벽가스감지기(113) 또는 상기 흡수탱크가스감지기(134C)에 의해 누출된 암모니아 가스가 기결정된 감지기준 이상으로 감지되는 것"으로 정의된다. 상기 가스흡수모드 운전은, 누출가스감지단계, 공기강제주입단계, 누출가스제거단계, 정제공기순환단계를 포함하며, 여기에 더불어 잔존가스제거단계, 내부흡수액배수단계를 더 포함할 수 있다.17 is a view for explaining the gas absorption mode of the ammonia release prevention and removal device of the present invention. As described above, gas absorption mode operation is performed when ammonia leak occurs. In the present invention, “ammonia leak” means “a leak caused by the outer enclosure wall gas detector 113 or the absorption tank gas detector 134C. It is defined as "ammonia gas is detected above a predetermined detection standard". The gas absorption mode operation includes a leak gas detection step, an air forced injection step, a leak gas removal step, and a purified air circulation step, and may further include a residual gas removal step and an internal absorbent liquid drainage step.
상기 누출가스감지단계에서는, 상기 외곽밀폐벽가스감지기(113) 또는 상기 흡수탱크가스감지기(134C)에 의해 누출된 암모니아 가스가 기결정된 감지기준 이상으로 감지되어, 상기 환기유입로(111) 및 상기 공기배기로(137C)가 폐쇄되어 상기 외곽밀폐벽(110) 및 상기 흡수탱크(130C) 내부공간이 외부와 격리된다.In the leak gas detection step, the ammonia gas leaked by the outer enclosure wall gas detector 113 or the absorption tank gas detector 134C is detected as higher than a predetermined detection standard, and the ventilation inlet 111 and the The air exhaust path 137C is closed so that the outer wall 110 and the inner space of the absorption tank 130C are isolated from the outside.
상기 공기강제주입단계에서는, 상기 공기주입기(116)를 통해 상기 외곽밀폐벽(110) 내부공간으로 주입된 공기가 암모니아와 혼합되어 상기 환기배출로(112)로 배출된다. 앞서 상기 정상운전모드에서는 송풍기에 의하여 강제송풍이 이루어짐으로써 공기 흐름의 구동력이 인가되었으나, 상기 가스흡수모드 운전 시에는 외부와의 완전한 격리가 이루어지므로 송풍기들이 공기 흐름의 구동력을 인가하지 못한다. 따라서 암모니아 누출 발생 초기에는 상기 외곽밀폐벽(110) 내부공간으로부터 상기 흡수탱크(130C) 내부공간으로 공기를 적극적으로 흘려보내기 위한 구동력이 상기 공기주입기(116)에 의해 인가될 수 있다. 한편 흡수액에 의한 암모니아 흡수가 시작되면 암모니아가 차지하고 있던 부피만큼이 비게 됨에 따라 상기 흡수탱크(130C) 내부공간의 압력이 상기 외곽밀폐벽(110) 내부공간의 압력보다 낮아지게 되며, 그러면 굳이 구동력을 인가하지 않아도 자연스럽게 공기가 상기 외곽밀폐벽(110) 내부공간으로부터 상기 흡수탱크(130C) 내부공간으로 흘러갈 수 있게 된다. 이 때 내부공간의 압력이 대기압보다 떨어지는 것은 지양하는 것이 바람직하므로, 이 시점에서는 상기 공기주입기(110)는 압력감지기(116p)에 의해 감지된 상기 외곽밀폐벽(110) 내부공간 압력이 대기압을 유지하도록 상기 외곽밀폐벽(110) 내부에 공기를 주입하는 역할을 하게 된다.In the air forced injection step, the air injected into the inner space of the outer enclosure wall 110 through the air injector 116 is mixed with ammonia and discharged to the ventilation outlet 112 . Previously, in the normal operation mode, forced blowing was performed by the blower to apply the driving force of the air flow. However, in the gas absorption mode, the blowers do not apply the driving force of the air flow because complete isolation from the outside is achieved. Therefore, in the initial stage of leakage of ammonia, the air injector 116 may apply a driving force for actively flowing air from the inner space of the outer enclosure wall 110 to the inner space of the absorption tank 130C. On the other hand, when the absorption of ammonia by the absorption liquid starts, as much as the volume occupied by ammonia is emptied, the pressure in the inner space of the absorption tank 130C becomes lower than the pressure in the inner space of the outer enclosure wall 110. Air can naturally flow from the inner space of the outer enclosure wall 110 to the inner space of the absorption tank 130C without being applied. At this time, since it is desirable to avoid that the pressure in the inner space is lower than the atmospheric pressure, at this time, the air injector 110 maintains the pressure in the inner space of the outer enclosure wall 110 detected by the pressure sensor 116p at atmospheric pressure. It serves to inject air into the outer enclosure wall 110 so as to do so.
상기 누출가스제거단계에서는, 흡수액과 상기 환기배출로(112)를 통해 배출된 암모니아 및 공기의 혼합물이 상기 이젝터(135C)로 각각 공급되어 혼합되어 분사되는 과정에서 암모니아가 흡수액에 용해되어 제거된다. 앞서 설명한 바와 같이 상기 이젝터(135C)는 원래 그 장치 특성상 두 개의 유입구로 유입된 액체들을 매우 활발하게 혼합하여 줄 수 있다. 이 과정에서 흡수액과 암모니아의 접촉이 아주 활발하게 이루어지며, 따라서 상기 이젝터(135C)를 통과함으로써 매우 고효율로 암모니아의 제거가 이루어질 수 있게 되는 것이다.In the step of removing the leaked gas, the mixture of the absorbent liquid, ammonia and air discharged through the ventilating discharge path 112 is supplied to the ejector 135C, mixed, and injected, whereby the ammonia is dissolved in the absorbent liquid and removed. As described above, the ejector 135C can very actively mix the liquids introduced into the two inlets due to its device characteristics. In this process, contact between the absorption liquid and ammonia is very active, and therefore, ammonia can be removed with very high efficiency by passing through the ejector 135C.
부연하자면, 이 과정에서 상기 이젝터(135C)로 제공되는 흡수액은, 기본적으로는 도 17에 도시된 바와 같이 상기 흡수액순환펌프(136C)에 의하여 끌어올려진 상기 흡수탱크(130C) 하측에 수용된 흡수액이 상기 펌프-이젝터유로(136Ca)를 통해 상기 이젝터(135C)로 제공될 수 있다. 그런데, 상기 이젝터(135C)에서 분사되어 배출된 흡수액은 그대로 떨어져내려 상기 흡수탱크(130C) 하측에 수용되게 되는데, 이 흡수액은 이미 암모니아를 흡수한 상태가 된다. 즉 시간이 지날수록 상기 흡수탱크(130C) 하측에 수용된 흡수액의 암모니아 농도는 올라갈 수밖에 없으며, 이에 따라 암모니아 흡수효율이 시간이 지남에 따라 떨어질 우려가 있다. 이러한 문제를 방지하기 위한 것이 앞서 설명한 도 22의 제3응용구성로서, 이 경우 상기 암모니아 방출방지 및 제거장치(100C)는, 상기 흡수탱크(130C) 내 흡수액을 보충하는 흡수액주입기(138C); 를 포함한다. 또한 이 때 상기 누출가스제거단계는, 상기 흡수액주입기(138C)에서 주입되는 흡수액 일부가 우회되어 상기 펌프-이젝터유로(136Ca)를 통해 상기 이젝터(135C)로 제공되도록 이루어지게 된다. 이와 같이 함으로써 상기 이젝터(135C)로는 항상 새로운 흡수액, 즉 암모니아를 흡수한 적이 없는 흡수액이 제공될 수 있게 되어, 시간이 지나더라도 암모니아 흡수효율이 떨어지지 않게 할 수 있다.To elaborate, in this process, the absorbent liquid supplied to the ejector 135C is basically the absorbent liquid accommodated in the lower side of the absorption tank 130C pulled up by the absorbent liquid circulation pump 136C as shown in FIG. It may be provided to the ejector 135C through the pump-ejector passage 136Ca. However, the absorbent liquid ejected from the ejector 135C falls as it is and is accommodated in the lower side of the absorption tank 130C, and the absorbent liquid has already absorbed ammonia. That is, as time passes, the ammonia concentration of the absorption liquid accommodated in the lower side of the absorption tank 130C inevitably increases, and accordingly, the ammonia absorption efficiency may decrease over time. To prevent this problem, as the third application configuration of FIG. 22 described above, in this case, the ammonia release prevention and removal device 100C includes an absorption liquid injector 138C for replenishing absorption liquid in the absorption tank 130C; includes In addition, at this time, in the step of removing the leaked gas, a portion of the absorbent liquid injected from the absorbent liquid injector 138C is bypassed and provided to the ejector 135C through the pump-ejector passage 136Ca. In this way, a new absorption liquid, that is, an absorption liquid that has never absorbed ammonia can be always provided to the ejector 135C, so that the efficiency of ammonia absorption does not decrease over time.
상기 정제공기순환단계에서는, 상기 이젝터(135C)를 통과하면서 암모니아가 제거되어 정제된 공기가 상기 공기순환로(133C)를 통해 상기 외곽밀폐벽(110)으로 복귀되어 순환된다. 이후 상기 누출가스제거단계 및 상기 정제공기순환단계가 순차적으로 순환 반복 수행되게 된다. 상기 누출가스제거단계에서 일차적으로 상기 이젝터(135C)에 유입된 공기에서 암모니아가 완전히 제거되지 않았다 하더라도, 일차적으로 정제된 공기가 상기 외곽밀폐벽(110)으로 복귀되면서 상기 외곽밀폐벽(110) 내부공간의 공기 중 암모니아 농도는 떨어지게 된다. 즉 1회차 순환 시에 비해 2회차 순환 시에 암모니아 농도가 떨어지는 것은 당연하며, 따라서 순환 회차가 증가함에 따라 공기 중 암모니아 농도는 단계적으로 계속 떨어지게 될 수 있는 것이다.In the purified air circulation step, the air purified by removing ammonia while passing through the ejector 135C is returned to the outer enclosure wall 110 and circulated through the air circulation path 133C. Thereafter, the leaked gas removal step and the purified air circulation step are sequentially and repeatedly cycled. Even if ammonia is not completely removed from the air primarily introduced into the ejector 135C in the leakage gas removal step, the primarily purified air is returned to the outer enclosure wall 110 and inside the outer enclosure wall 110. The concentration of ammonia in the air in the space falls. That is, it is natural that the ammonia concentration decreases during the second cycle compared to the first cycle, and therefore, as the number of cycles increases, the ammonia concentration in the air can continue to drop step by step.
상기 잔존가스제거단계 및 상기 내부흡수액배수단계는, 이처럼 공기가 상기 흡수탱크(130C) 및 상기 외곽밀폐벽(110)을 순환하면서 암모니아가 제거되는 과정과 병행하여 이루어진다. 즉 상기 흡수탱크(130C)에서만 암모니아 제거가 이루어지는 것이 아니라, 상기 외곽밀폐벽(110) 안에서도 암모니아 제거가 추가적으로 더 이루어지게 하기 위한 단계인 것이다. 이를 위하여, 상기 암모니아 방출방지 및 제거장치(100C)는, 상기 배수조(114) 및 상기 외곽밀폐벽내부흡수액분사기(115)를 포함한다.The residual gas removal step and the internal absorbent liquid draining step are performed in parallel with a process in which ammonia is removed while air circulates through the absorption tank 130C and the outer enclosure wall 110 . That is, this is a step for allowing ammonia to be removed not only in the absorption tank 130C, but also in the outer enclosure wall 110 to be additionally removed. To this end, the device for preventing and removing ammonia (100C) includes the water tank 114 and the absorbent liquid injector 115 inside the outer sealing wall.
상기 잔존가스제거단계에서는, 상기 누출가스제거단계 및 상기 정제공기순환단계에서 상기 외곽밀폐벽내부흡수액분사기(115)가 흡수액을 분사하여 상기 외곽밀폐벽(110) 내부공간의 잔존 암모니아 가스를 제거한다. 이 과정에서 상기 외곽밀폐벽(110) 내에 약간의 흡수액이 채워지게 되며, 이 흡수액이 상기 암모니아 사용설비(500)에 접촉하면 설비에 고장이 발생할 우려가 있겠으나, 상기 배수조(114)가 상기 암모니아 사용설비(500)가 서있는 바닥면보다 더 함몰되게 형성되어 있으므로 흡수액은 상기 배수조(114)로 원활하게 흘러들어가 수용되며, 따라서 흡수액이 상기 암모니아 사용설비(500)에 접촉할 위험성이 거의 제거된다.In the residual gas removal step, the outer enclosure wall internal absorbent liquid injector 115 injects the absorbent liquid in the leak gas removal step and the purified air circulation step to remove the remaining ammonia gas in the inner space of the outer enclosure wall 110 . In this process, some absorbent liquid is filled in the outer enclosure wall 110, and if this absorbent liquid contacts the ammonia using equipment 500, there is a possibility that the equipment may fail. Since the ammonia using equipment 500 is formed to be more depressed than the bottom surface on which it stands, the absorption liquid smoothly flows into the water tank 114 and is accommodated, and thus the risk of the absorption liquid coming into contact with the ammonia using equipment 500 is almost eliminated. .
상기 내부흡수액배수단계에서는, 앞서 설명한 바와 같이 상기 외곽밀폐벽(110) 내부공간에 흘러들어온 흡수액이 모여서 상기 배수조(114)에 수용된 후에, 상기 배수조(114)에 적당히 흡수액이 차오르면 상기 배수조배수밸브(114v)에 의해 배수가 이루어지게 한다. 이에 따라 흡수액에 의한 상기 암모니아 사용설비(500) 접촉 위험성은 완전히 제거된다.In the internal absorbent draining step, as described above, after the absorbent liquid flowing into the inner space of the outer sealing wall 110 is collected and accommodated in the drain tank 114, when the absorbent liquid fills the drain tank 114 appropriately, the drain Drainage is made by the water tank drain valve 114v. Accordingly, the risk of contact with the ammonia using facility 500 by the absorption liquid is completely eliminated.
도 18은 본 발명의 암모니아 방출방지 및 제거장치의 추가흡수모드를 설명하기 위한 도면이다. 앞서 설명한 바와 같이 가스흡수모드에서의 암모니아 누출량 예상치보다 더 많이 누출이 발생하는 특수한 경우 추가흡수모드 운전이 수행되게 되는데, 보다 명확히 설명하자면, 상기 외곽밀폐벽가스감지기(113) 또는 상기 흡수탱크가스감지기(134C)에 의해 누출된 암모니아 가스가 기결정된 최대기준 이상으로 감지되면, 상기 가스흡수모드와 병행하여 추가흡수모드 운전이 수행된다. 여기에서 "최대기준"은 당연히 "감지기준"보다 높은 값으로 결정된다. 상기 추가흡수모드 운전은, 누출추가판단단계, 신규흡수액보충단계, 사용흡수액배출단계를 포함할 수 있다.18 is a view for explaining an additional absorption mode of the ammonia release prevention and removal device of the present invention. As described above, additional absorption mode operation is performed in a special case where ammonia leakage is more than expected in the gas absorption mode. To be more clearly explained, the outer enclosure wall gas detector 113 or the absorption tank gas detector When the leaked ammonia gas is sensed to be greater than or equal to a predetermined maximum standard by 134C, an additional absorption mode operation is performed in parallel with the gas absorption mode. Here, the "maximum criterion" is naturally determined to be a higher value than the "detection criterion". The operation in the additional absorption mode may include a step of determining additional leakage, a step of replenishing a new absorbent liquid, and a step of discharging the used absorbent liquid.
이러한 추가흡수모드가 필요한 이유에 대하여 간략히 설명하자면 다음과 같다. 암모니아 사용설비(500)에서 원치않은 암모니아 누출이 발생할 위험성은 이미 알려져 있는 것이고, 따라서 어떤 요인으로 누출이 발생하는지, 어느 정도의 양으로 누출이 발생하는지 정도는 실상 어느 정도 파악되어 있는 상태이다. 한편 암모니아 흡수가 최대한 잘 이루어지게 하기 위해서라면, 흡수액을 최대한 많은 양을 준비하고 항상 신선한 흡수액이 공급되도록 하면 좋을 것이다. 그러나 실제로는 이러한 큰 설비를 운용하고 유지하는데 큰 비용이 들어가기 때문에 무한정 흡수액 운용량을 늘리는 것에는 한계가 있다. 예를 들어 흡수액 보관용기를 지나치게 크게 지을 경우 공간이 부족하게 될 우려가 있으며, 흡수액을 순환시키는 펌프 또한 지나치게 대용량을 사용할 경우 전력 소모가 너무 심해지게 된다. 이러한 점들을 고려하여, 경험적으로 암모니아 누출이 발생하는 경우들, 예를 들어 배관 이음새나 밸브 노후화로 인한 누출 등과 같은 경우들에서 미리 누출량이 어느 정도 수준인지 파악하고, 이 수준에 맞추어 흡수액 운용량을 결정하는 것이다. 바로 이것이 앞서 설명한 "최대기준"이 된다. 그런데, 실제로 설비를 운용하는 과정에서 정말로 예상치 못한 원인으로, 즉 예를 들자면 실무자가 암모니아 사용설비(500) 주변에서 다른 작업을 하다가 실수로 설비에 흠집을 냈다거나 하는 등과 같은 사고가 발생할 수 있으며, 이러한 경우 일반적인 예상치(즉 "최대기준")보다 훨씬 많은 누출이 발생하게 된다. 추가흡수모드는 바로 이러한 경우를 대비한 것으로서, 즉 꼭 필요한 경우에 추가적으로 수행될 수 있는 모드일 뿐 항상 수행되는 모드인 것은 아니다.The reason why this additional absorption mode is necessary is briefly explained as follows. The risk of unwanted ammonia leakage from the ammonia using facility 500 is already known, and therefore, what causes leakage and how much leakage occurs are actually known to some extent. On the other hand, in order to achieve maximum ammonia absorption, it would be good to prepare the maximum amount of absorbent liquid and to ensure that fresh absorbent liquid is always supplied. However, in practice, there is a limit to increasing the amount of absorbent liquid indefinitely because it costs a lot to operate and maintain such a large facility. For example, if an absorbent liquid storage container is built too large, space may be insufficient, and if an excessively large-capacity pump is used to circulate the absorbent liquid, power consumption becomes severe. Considering these points, in cases where ammonia leakage occurs, for example, in cases such as leakage due to pipe joints or aging valves, the level of leakage is determined in advance, and the amount of absorbent liquid is adjusted according to this level. is to decide This is the "maximum standard" described above. However, in the process of actually operating the facility, an accident may occur due to a really unexpected cause, that is, for example, a practitioner accidentally scratches the facility while doing other work around the ammonia using facility 500, In this case, leakage will be far greater than is normally expected (i.e. "maximum standard"). The additional absorption mode is prepared for such a case, that is, it is a mode that can be additionally performed when absolutely necessary, but is not a mode that is always performed.
상기 누출추가판단단계에서는, 상기 외곽밀폐벽가스감지기(113) 또는 상기 흡수탱크가스감지기(134C)에 의해 누출된 암모니아 가스가 기결정된 최대기준 이상으로 판단된다. 암모니라 누출량이 최대기준 이상이라는 것은, 설계 시 충분히 암모니아 제거가 가능할 것으로 예상했던 흡수액 운용량으로는 암모니아를 충분히 제거할 수 없다는 것을 의미한다. 따라서 상기 추가흡수모드에서는, 새로운 흡수액을 더 보충해 주고, 암모니아를 충분히 흡수한 흡수액은 배출하여 주는 단계들을 포함한다. 이를 위하여 상기 암모니아 방출방지 및 제거장치(100C)는, 상기 펌프-배출유로(136Cc) 및 상기 흡수액주입기(138C)를 더 구비한다.In the leakage additional determination step, it is determined that the leaked ammonia gas is equal to or greater than a predetermined maximum standard by the outer enclosure wall gas detector 113 or the absorption tank gas detector 134C. The fact that the amount of ammonia leakage exceeds the maximum standard means that ammonia cannot be sufficiently removed with the operating amount of the absorbent, which was expected to be able to sufficiently remove ammonia in the design. Therefore, in the additional absorption mode, steps of replenishing a new absorption liquid and discharging the absorption liquid having sufficiently absorbed ammonia are included. To this end, the ammonia release prevention and removal device 100C further includes the pump-discharge passage 136Cc and the absorption liquid injector 138C.
상기 신규흡수액보충단계에서는, 상기 흡수액주입기(138C)에 의해 상기 흡수탱크(130C) 내에 새로운 흡수액이 보충된다. 이에 따라 최대기준 이상으로 누출된 암모니아가 새로 보충된 흡수액에 흡수되어 추가적으로 제거될 수 있게 된다.In the new absorbent liquid replenishment step, new absorbent liquid is replenished in the absorption tank 130C by the absorbent liquid injector 138C. Accordingly, ammonia leaked beyond the maximum standard is absorbed into the newly replenished absorption liquid and can be additionally removed.
상기 사용흡수액배출단계에서는, 상기 흡수탱크(130C) 하측에 수용된 흡수액이 상기 흡수액순환펌프(136C)에 의해 상기 흡수액순환유로(136Cp)를 통해 끌어올려져 그 중 전체 또는 일부가 상기 펌프-배출유로(136Cc)를 통해 외부로 배출된다. 즉 암모니아 농도가 높아진 흡수액은 꾸준히 배출하여 주고, 그 자리에 암모니아를 흡수한 적이 없는 새로운 흡수액을 꾸준히 보충하여 줌으로써, 암모니아 누출량이 예상치 이상이라 하더라도 암모니아의 추가적인 제거가 원활하게 이루어질 수 있다.In the step of discharging the used absorbent liquid, the absorbent liquid accommodated in the lower side of the absorption tank 130C is pulled up through the absorbent liquid circulation passage 136Cp by the absorbent liquid circulation pump 136C, and all or part thereof is passed through the pump-discharge passage. (136Cc) is discharged to the outside. That is, by continuously discharging the absorbent liquid having a high ammonia concentration and continuously replenishing the new absorbent liquid that has not absorbed ammonia in its place, additional removal of ammonia can be smoothly performed even if the amount of ammonia leakage is greater than expected.
도 19는 본 발명의 암모니아 방출방지 및 제거장치의 복구운전모드를 설명하기 위한 도면이다. 앞서 설명한 바와 같이 가스흡수모드에서 충분히 암모니아를 흡수하여 모두 제거한 뒤에는 다시 평상시의 정상운전모드로 되돌아와야 하는데, 이를 위한 여러 준비단계들이 수행되는 동작모드가 바로 복구운전모드이다. 즉 상기 가스흡수모드 운전 이후에, 상기 외곽밀폐벽가스감지기(113) 또는 상기 흡수탱크가스감지기(134C)에 의해 누출된 암모니아 가스가 기결정된 감지기준 미만으로 감지되면, 복구운전모드 운전이 수행되는 것이다. 상기 복구운전모드는, 누출미발생판단단계, 흡수탱크격리단계, 신규흡수액보충단계, 사용흡수액배출단계를 포함할 수 있다.19 is a view for explaining the recovery operation mode of the ammonia emission prevention and removal device of the present invention. As described above, after sufficiently absorbing ammonia in the gas absorption mode and removing all of the ammonia, it is necessary to return to the normal operation mode again. That is, after the gas absorption mode operation, when the ammonia gas leaked by the outer enclosure wall gas detector 113 or the absorption tank gas detector 134C is detected to be less than a predetermined detection standard, recovery operation mode operation is performed will be. The recovery operation mode may include a step of determining whether leakage has occurred, a step of isolating the absorption tank, a step of replenishing a new absorbent liquid, and a step of discharging the used absorbent liquid.
상기 누출미발생판단단계에서는, 상기 외곽밀폐벽가스감지기(113) 또는 상기 흡수탱크가스감지기(134C)에 의해 누출된 암모니아 가스가 기결정된 감지기준 미만으로 판단된다. 그러면 이제 상기 복구운전모드가 시작되게 된다.In the leakage non-occurrence determination step, the leaked ammonia gas is determined to be less than a predetermined detection standard by the outer enclosure wall gas detector 113 or the absorption tank gas detector 134C. Then, the recovery operation mode starts.
상기 흡수탱크격리단계에서는, 상기 이젝터(135C)로 공급되는 흡수액 공급이 중단되고, 상기 공기순환로밸브(133Cv)가 폐쇄되어, 상기 외곽밀폐벽(110) 및 상기 흡수탱크(130C) 간에 공기순환이 중단되도록 서로 격리된다. 이 시점에서 상기 외곽밀폐벽(110) 내에 만약 흡수액이 잔존하여 있다면, 상기 배수조(114)에서 이를 배수하는 과정이 함께 이루어질 수도 있다.In the absorption tank isolation step, the supply of the absorbent liquid to the ejector 135C is stopped, the air circulation passage valve 133Cv is closed, and air circulation between the outer enclosure wall 110 and the absorption tank 130C is achieved. are isolated from each other so as to cease. At this point, if the absorbent liquid remains in the outer enclosure wall 110, a process of draining it from the drain tank 114 may also be performed.
상기 신규흡수액보충단계에서는 상기 추가흡수모드에서와 마찬가지로, 상기 흡수액주입기(138C)에 의해 상기 흡수탱크(130C) 내에 새로운 흡수액이 보충된다.In the new absorbent liquid supplementing step, as in the additional absorption mode, new absorbent liquid is replenished in the absorption tank 130C by the absorbent liquid injector 138C.
상기 사용흡수액배출단계에서는 역시 상기 추가흡수모드에서와 마찬가지로, 상기 흡수탱크(130C) 하측에 수용된 흡수액이 상기 흡수액순환펌프(136C)에 의해 상기 흡수액순환유로(136Cp)를 통해 끌어올려져 상기 펌프-배출유로(136Cc)를 통해 외부로 배출된다.In the step of discharging the used absorbent liquid, as in the additional absorption mode, the absorbent liquid accommodated in the lower side of the absorption tank 130C is pulled up through the absorbent liquid circulation passage 136Cp by the absorbent liquid circulation pump 136C, and the pump- It is discharged to the outside through the discharge passage (136Cc).
이러한 과정을 거쳐 흡수액이 교체됨으로써 이후 암모니아 제거에 사용될 수 있을 만큼 충분히 흡수액의 암모니아 농도가 떨어지게 되면, 상기 복구운전모드가 종료되고 상기 환기유입로(111), 상기 환기배출로(112) 등이 개방되어 상기 정상운전모드가 다시 수행되게 된다.When the absorbent liquid is replaced through this process and the ammonia concentration of the absorbent liquid drops sufficiently to be used for ammonia removal thereafter, the recovery operation mode ends and the ventilation inlet 111 and the ventilation outlet 112 are opened. Then, the normal operation mode is performed again.
본 발명에 의하면, 설비에 암모니아를 흡수하는 흡수탱크를 구비함으로써, 가연성 및 독성을 모두 가지는 암모니아가 설비에서 누출되더라도 대기 방출 시 신속하고 안전하게 희석하여 제거시켜 설비안정성 및 사용자안전성을 크게 향상시킬 수 있다.According to the present invention, by providing an absorption tank for absorbing ammonia in a facility, even if ammonia, which has both flammable and toxic properties, leaks from the facility, it is quickly and safely diluted and removed when released into the atmosphere, thereby greatly improving facility stability and user safety. .
