Description

가스화기의 냉각 장치{CHILLER OF GASIFIER}Cooling device of gasifier {CHILLER OF GASIFIER}

본 발명은 가스화기에 관한 것으로서, 더욱 상세하게는 가스화기에서 가스화 반응을 진행하면서 생성된 생성가스와 불연성분인 슬랙을 냉각시켜 배출시키는 가스화기의 냉각 장치에 관한 것이다.The present invention relates to a gasifier, and more particularly, to a gasifier cooling apparatus for cooling and discharging a generated gas and a nonflammable slack while performing a gasification reaction in a gasifier.

일반적으로 고온, 고압 조건에서 운전되는 가스화기의 경우 공급되는 시료(석탄, 폐유 등등..)가 산화제와 가스화 반응을 진행하면서 시료중에 함유된 가연성분은 생성가스(일산화탄소, 수소)로 전환되고 불연성분인 회재(灰災)는 용융되어 슬랙(slag) 형태로 배출된다.In general, in the case of gasifiers operated under high temperature and high pressure conditions, the supplied sample (coal, waste oil, etc.) undergoes a gasification reaction with an oxidizing agent, and the combustible components contained in the sample are converted into generated gases (carbon monoxide, hydrogen) and are nonflammable. The ash ash, which is powder, is melted and discharged in the form of slag.

이 때 배출되는 생성가스와 슬랙은 상당히 높은 온도에서 배출이 이루어지므로 냉각 과정을 거치게 되는데, 보통의 생성가스 경우에는 냉각수의 직접 분사에 의한 급냉 방식의 냉각 타워(Water Spray Tower)를 통과하며 냉각이 이루어지거나 열교환기를 통과하면서 냉각시키는 간접 열교환 방식을 적용하며, 슬랙의 경우에는 냉각수 저장조에 고온의 용융 슬랙이 떨어지면서 급냉되는 방식을 별도로 적용하고 있다.At this time, the generated gas and slack are discharged at a considerably high temperature, and thus undergo a cooling process. In the case of ordinary product gas, the cooling gas is passed through a water spray tower by direct injection of cooling water. It is made of indirect heat exchange to cool down while passing through or through a heat exchanger, and in the case of slag, the method of quenching as the molten slag of high temperature falls in the cooling water reservoir is applied separately.

도 1은 종래의 가스화기 냉각시스템을 도시한 개략도로서, 가스화 반응을 진행하는 가스화기(1)와, 가스화기(1)의 후단에 냉각수가 직접 분사되어 급냉시키는 냉각타워(2)와, 급냉된 생성가스에 포함된 입자를 제거하는 집진장치(3)로 구성된다.FIG. 1 is a schematic diagram showing a conventional gasifier cooling system, including a gasifier 1 for performing a gasification reaction, a cooling tower 2 for quenching water by direct injection of cooling water into the rear end of the gasifier 1, and quenching. It is composed of a dust collector (3) for removing the particles contained in the generated product gas.

여기서 원통의 가스화기(1)는 상단부에는 생성가스가 배출되어 냉각타워(2)로 유입되는 토출구(4)가 형성되고, 하부에는 냉각수가 담겨져 있는 퀀처(Quencher:5)와 퀀처(5)내에 용융슬랙을 냉각수로 잘 흘러 들어가도록 유도하는 슬랙탭(slag tap:6)이 형성된다. 그리고 가스화기(1)의 내측으로는 고온 및 고압에 견딜 수 있는 내화재(7)가 겹겹히 설치되며, 그 내화재(7)를 관통한가스화기(1)의 측부에 시료 및 산화재가 투입되는 투입구(8)가 설치된다.Here, the gasifier 1 of the cylinder has a discharge port 4 through which the generated gas is discharged into the cooling tower 2 at the upper end thereof, and in the quencher 5 and the quencher 5 containing the cooling water at the lower part thereof. Slag taps (6) are formed to guide the molten slack into the coolant well. And inside the gasifier 1, the refractory material 7 which can withstand high temperature and high pressure is overlapped, and the inlet which a sample and an oxidant material are injected into the side of the gasifier 1 which penetrated the fireproof material 7 is carried out. (8) is installed.

상기 투입구(8)를 통하여 투입된 시료(폐유, 미분탄 등등..)와 산화재는 가스화기(1) 내에서 가스화 반응을 진행하면서 시료중에 함유된 생성가스가 가스화기(1) 상단의 토출구(4)로 빠져나가 냉각타워(2)로 유입된다. 냉각타워(2)에서는 냉각수의 분사에 의하여 고온의 생성가스가 냉각되며, 냉각된 생성가스는 집진장치(3)를 통과하면서 입자가 제거된다.Samples (waste oil, pulverized coal, etc.) and oxidant injected through the inlet 8 undergo a gasification reaction in the gasifier 1 while the generated gas contained in the sample is discharged from the upper part of the gasifier 1. It exits and enters the cooling tower (2). In the cooling tower 2, the hot product gas is cooled by the injection of cooling water, and the cooled product gas passes through the dust collector 3 to remove particles.

한편, 가스화기(1)내에서 발생되는 불연성분인 회재는 용융되어 슬랙 형태로 슬랙탭(6)의 냉각수에 떨어져 급냉시키게 된다.On the other hand, the ash which is a nonflammable component generated in the gasifier 1 is melted and quenched by falling into the cooling water of the slack tab 6 in the form of slack.

그러나 이러한 종래 가스화기는 별도의 냉각장치를 설치하여야 하기 때문에 공간이 필요하고 설치비용이 증가하게 된다. 또한, 냉각타워를 설치하여 생성가스를 냉각시키는 방식에서는 고온의 생성가스와 분무되는 냉각수와의 접촉에 의하여 급냉이 이루어지지만 분무되는 냉각수가 수증기로 증발되면서 배기가스의 유량이 급격히 증가하게 되므로 후단 공정의 설비 또한 그 규모가 커지게 되며 후단 공정에서 온도가 낮아질 경우에는 수증기가 재차 냉각됨에 따라 응축수가 발생되는 문제점이 있었다.However, such a conventional gasifier requires a separate cooling device, so space is required and installation cost is increased. In addition, in the method of cooling the product gas by installing a cooling tower, rapid cooling is performed by the contact of the hot product gas with the sprayed cooling water, but the flow rate of the exhaust gas is rapidly increased as the sprayed cooling water is evaporated with water vapor, and thus the subsequent process. In addition, the size of the facility is also large, if the temperature is lowered in the subsequent process, there was a problem that the condensate occurs as the water vapor is cooled again.

본 발명은 상술한 바와 같은 종래의 문제점을 해결하기 위한 것으로서, 가스화기에서 생성된 고온의 생성가스와 슬랙을 냉각시키기 위하여 각각 별도의 냉각장치를 적용하는 것이 아니라 그 기능이 통합된 하나의 퀀처에서 이루어지는 가스화기 냉각장치를 제공하는데 그 목적이 있다.The present invention is to solve the conventional problems as described above, in order to cool the high-temperature generated gas and slack produced in the gasifier, respectively, rather than applying a separate cooling device in one quencher integrated its function It is an object of the present invention to provide a gasifier cooling device.

상기의 목적을 달성하기 위하여 본 발명은, 가스화기 본체 하부에 위치하는 퀀처 내부에 슬랙탭으로부터 생성가스와 슬랙을 유도하여 냉각 처리할 수 있도록 원통관이 하방으로 이어지며, 내경이 점점 확대된 하부는 다수개의 통공과 같이 냉각수에 담겨지게 설치되는 안내관과; 상기 퀀처내에 담겨져 있는 냉각수 수위를 감지하는 레벨게이지와; 상기 레벨게이지에 의하여 측정된 냉각수 수위를 통제하는 콘트롤 밸브로 이루어진 것을 특징으로 하는 가스화기의 냉각 장치를 제공한다.In order to achieve the above object, the present invention, the cylindrical tube is directed downward to guide the cooling gas and slack from the slack tap inside the quencher located in the lower part of the gasifier body, the inner diameter is gradually expanded The guide pipe is installed to be contained in the coolant, such as a plurality of through holes; A level gauge which senses the level of the coolant contained in the quencher; Provided is a cooling device for a gasifier comprising a control valve for controlling the coolant level measured by the level gauge.

도 2는 본 발명에 따른 가스화기의 냉각 장치의 확대 구성도이다.2 is an enlarged configuration diagram of a cooling device of a gasifier according to the present invention.

고온의 생성가스 및 용융슬랙을 냉각시키기 위한 가스화기(10)는 본체(12)와 본체(12) 하부로 이어진 퀀처(20)로 구성된다.The gasifier 10 for cooling the hot product gas and the molten slag is composed of a body 12 and a quencher 20 connected to the bottom of the body 12.

여기서 본체(12)는 고온에서의 반응을 위하여 그 내벽에 겹겹의 내화재(14)가 설치되며, 본체(12)의 하부에는 가스화반응에 의해 용융되어 흘러내리는 용융슬랙을 유도하기 위한 슬랙탭(16)이 설치된다.Here, the main body 12 has a layer of fireproof material 14 installed on its inner wall for reaction at a high temperature, and a slack tab 16 for inducing a molten slag that is melted and flowed down by a gasification reaction under the main body 12. ) Is installed.

그리고 하방으로 갈수록 내경이 축소되는 깔대기 형상의 퀀처(20)는 생성된 생성가스가 배출되는 가스배출구(21)가 일측에 설치되며, 하면에는 슬랙이 저장조(80)로 떨어지는 슬랙배출구(22)가 설치된다. 그리고 퀀처(20) 내부에 슬랙탭(16)으로부터 이어져 슬랙탭(16)을 통하여 빠져나오는 용융슬랙과 고온의 생성가스를 유도하는 안내관(30)이 축방향으로 설치된다.In addition, the funnel-shaped quencher 20 of which the inner diameter is reduced toward the lower side is provided with a gas outlet 21 through which the generated product gas is discharged, and a slag outlet 22 in which the slag falls into the storage tank 80 is provided on the lower surface thereof. Is installed. In addition, a guide tube 30 for guiding the molten slack and hot gas generated from the slack tab 16 through the slack tab 16 is provided in the quench 20 in the axial direction.

안내관(30)은 부식에 강한 스테인레스 재질로 제작된다.Guide tube 30 is made of a stainless steel resistant to corrosion.

안내관(30)은 측부에 분무노즐(42)과 분무노즐(42)에 냉각수를 공급하는 냉각수 유입관(40)이 대향되는 상태로 설치된다.The guide tube 30 is installed in a state in which a cooling water inlet pipe 40 for supplying cooling water to the spray nozzle 42 and the spray nozzle 42 is opposed to the side.

또한, 안내관(30)은 하부로 이어질수록 내경이 확대되며, 확대된 하부 외주면에는 불규칙적으로 다수개의 통공(32)이 형성된다.In addition, the inner diameter of the guide tube 30 extends as it extends downward, and a plurality of through holes 32 are irregularly formed on the enlarged lower outer circumferential surface.

그리고 안내관(30)의 확대된 하부는 퀀처(20)내에 일정한 수위로 담겨져 있는 냉각수(50)에 담겨지게 설치된다.And the enlarged lower portion of the guide tube 30 is installed to be contained in the cooling water 50 contained in a constant water level in the quencher (20).

한편, 퀀처(20)내에 담겨져 있는 냉각수(50)의 수위를 감지하는 레벨게이지(60)가 퀀처(20) 일측에 설치되며, 레벨게이지(60)에 의하여 측정된 냉각수(50) 수위를 통제하는 콘트롤 밸브(70)로 구성된다.On the other hand, the level gauge 60 for detecting the level of the coolant 50 contained in the quencher 20 is installed on one side of the quencher 20, and controls the level of the coolant 50 measured by the level gauge 60 It consists of a control valve 70.

이와 같이 구성된 본 발명에 따른 가스화기의 냉각 장치의 작동은 다음과 같다.Operation of the cooling device of the gasifier according to the present invention configured as described above is as follows.

가스화기(10) 내부에서 공급되는 시료와 산화제의 반응에 의하여 발생하는 생성가스와 용융슬랙은 가스화기(10)의 슬랙탭(16)을 통과하면서 퀀처(20)로 유입된다.The generated gas and the molten slag generated by the reaction of the sample supplied from the gasifier 10 and the oxidant are introduced into the quencher 20 while passing through the slack tab 16 of the gasifier 10.

용융슬랙은 슬랙탭(16)과 안내관(30)을 통과하면서 퀀처(20) 내부에 저장된 냉각수(50)에 떨어져 급냉되고, 슬랙배출구(22)를 통하여 저장조(80)로 떨어지게 된다.The molten slack is quenched by the coolant 50 stored in the quencher 20 while passing through the slack tab 16 and the guide tube 30, and falls into the storage tank 80 through the slack outlet 22.

생성가스는 슬랙탭(16)과 안내관(30)을 통과하면서 안내관(30)의 일측에 설치된 분무노즐(42)에서 분사되는 냉각수에 의하여 일차적으로 급냉이 이루어지게된다. 분무노즐(42)로 공급되는 냉각수는 냉각수 유입관(40)으로부터 공급된다.The product gas is primarily quenched by the cooling water sprayed from the spray nozzle 42 installed on one side of the guide tube 30 while passing through the slack tab 16 and the guide tube 30. The cooling water supplied to the spray nozzle 42 is supplied from the cooling water inlet pipe 40.

상기 일차적으로 급냉된 생성가스는 퀀처(20) 내부의 냉각수(50)를 통과하면서 재차 냉각이 이루어진 후, 퀀처(20)의 가스배출구(21)를 통하여 후단 공정으로 빠져나가게 된다.The first quenched product gas is cooled again while passing through the cooling water 50 inside the quencher 20, and then exits to the subsequent process through the gas outlet 21 of the quencher 20.

한편, 생성가스를 냉각시키기 위하여 분무노즐(42)에서 분사되는 냉각수는 고온의 생성가스와 반응하면서 일부는 수증기로 전환되고 나머지는 안내관(30)의 벽면에 부딪치면서 아래로 떨어지는데, 고온의 생성가스 흐름을 유도하는 안내관(30)은 냉각수의 분무에 의하여 별도의 냉각장치 없이 과열되지 않는 상태로 보호된다.On the other hand, the cooling water injected from the spray nozzle 42 in order to cool the generated gas reacts with the hot product gas, partly converted into water vapor and the other part falls down while hitting the wall surface of the guide tube 30, the high temperature generation The guide tube 30 which guides the gas flow is protected without overheating by a spray of cooling water without a separate cooling device.

그리고 분무노즐(42)에서 분무되는 냉각수중 고온의 생성가스와 접촉하면서 수증기로 전환된 가스는 생성가스에 포함된 상태로 안내관(30)을 통하여 퀀처(20) 내부의 냉각수(50)와 2차적으로 접촉하면서 다시 액체 상태의 물로 전환된다.The gas converted into water vapor while being in contact with the hot product gas of the cooling water sprayed from the spray nozzle 42 is included in the product gas through the guide tube 30 and the cooling water 50 and 2 inside the quencher 20. Upon contact with each other, it is converted back into liquid water.

그런데 액체 상태의 물로 전환되는 냉각상태에서는, 수증기 상태에서 재차 응축되는 냉각수 및 분무되는 냉각수중 수증기로 전환되지 않고 안내관(30)을 냉각시키면서 떨어지는 냉각수(50)에 의하여 퀀처(20) 내부의 냉각수(50) 수위가 증가될 수 있으므로 증가되는 냉각수(50)의 수위를 레벨게이지(60)로 하여 감지하게 된다.However, in the cooling state that is converted to the water of the liquid state, the cooling water inside the quencher 20 by the cooling water 50 falling while cooling the guide tube 30 without being converted into the cooling water condensed again in the water vapor state and the sprayed cooling water. (50) Since the water level may be increased, the level of the cooling water 50 that is increased is detected as the level gauge 60.

따라서 퀀처(20) 내부의 냉각수(50) 수위는 레벨게이지(60)의 감지에 의한 신호가 콘트롤밸브(70)로 전달되어 조절된다.Therefore, the level of the coolant 50 inside the quencher 20 is controlled by transmitting a signal by sensing the level gauge 60 to the control valve 70.

레벨게이지(60)에서 냉각수(50)가 감지될 경우 콘트롤밸브(70)가 열리면서냉각수(50)를 외부로 배출하게 된다.When the coolant 50 is detected at the level gauge 60, the control valve 70 is opened to discharge the coolant 50 to the outside.

또한, 안내관(30)을 통하여 유도되는 생성가스는 안내관(30)의 통공(32)을 통하여 냉각수(50)와 접촉하면서 빠져나가게 된다. 통공(32)은 생성가스와 저장된 냉각수(50)와의 접촉이 촉진되어 냉각 효율이 증대되며, 통공(32)이 없을 경우 발생할 수 있는 퀀처(20) 내부 냉각수(50)의 큰 수위변동 및 가스화기(10) 내의 압력변동을 감소시키게 된다.In addition, the product gas guided through the guide tube 30 exits while contacting the cooling water 50 through the through-hole 32 of the guide tube 30. The through hole 32 facilitates the contact between the generated gas and the stored coolant 50 to increase the cooling efficiency, and the large water level fluctuation of the coolant 50 inside the quencher 20 that may occur when the through hole 32 is absent and the gasifier The pressure fluctuation in (10) is reduced.

이상에서는 본 발명을 특정의 바람직한 실시 예에 대하여 도시하고 또한 설명하였으나, 본 발명은 상술한 실시 예에 한정되지 아니하며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 이하 청구범위에 기재된 본 발명의 요지를 벗어남이 없이 다양한 변경실시가 가능할 것이다.Although the present invention has been illustrated and described with respect to certain preferred embodiments, the present invention is not limited to the above-described embodiments, and a person skilled in the art to which the present invention pertains has the present invention set forth in the claims below. Various modifications may be made without departing from the spirit of the invention.

이상에서 설명한 바와 같이 본 발명인 가스화기의 냉각 장치는, 가스화기에서 생성된 고온의 생성가스와 슬랙이 가스화기 하부 퀀처내에서 저장된 냉각수와 분무되는 냉각수에 의하여 냉각됨으로서, 냉각의 위한 별도 장치의 설치공간 확보가 필요없게 되었으며, 설비가 감소되어 비용이 절감되는 효과가 있다.As described above, the present invention provides a cooling device for a gasifier, in which a hot product gas and slag generated by the gasifier are cooled by the coolant sprayed with the coolant stored in the lower quencher and sprayed, thereby providing a separate device for cooling. There is no need to secure space, and the cost is reduced by reducing equipment.

또한, 퀀처 내부에 생성가스를 유도하기 위한 안내관은, 생성가스와 저장된 냉각수와의 접촉이 촉진되어 냉각 효율이 증대되는 효과가 있다.In addition, the guide tube for guiding the generated gas inside the quencher, the contact between the generated gas and the stored cooling water is promoted to increase the cooling efficiency.
