Description

선박용 관수전기가열시스템Irrigation electric heating system for ships
본 발명은 선박에서 연료유와 윤활유 등의 가열, 기기의 워밍, 업무 및 거주 구역의 난방 등에 쓰이는 열전달 매체인 증기를 생산하는 방식을 가지는 선박용 관수전기가열시스템에 관한 것이다.The present invention relates to an irrigation electric heating system for ships having a method of producing steam, which is a heat transfer medium used for heating fuel oil and lubricating oil, warming equipment, and heating work and living areas in ships.
부연하면, 본 발명은, 선박용 관수전기가열시스템은, 보조 보일러(21)의 연료유 버너(23)를 운전할 수 없는 경우, 순환수 펌프(12)를 이용하여 관수를 강제순환식 관수전기히터(11)로 공급되어 포화온도보다 낮은 온도로 가열된 후, 물인 상태로 보조 보일러(21)로 공급되면서 증기로 변환되면서 잠열로 흡수되고 포화온도로 변환되는 과정에서 발생된 증기를 이용하여, 상기 보조 보일러(21)가 증기히터(29)로 증기를 전달할 수 있도록 구성된, 선박용 관수전기가열시스템에 관한 것이다.In other words, in the present invention, when the fuel oil burner 23 of the auxiliary boiler 21 cannot be operated, the irrigation electric heating system for ships uses the circulation water pump 12 to supply irrigation water to the forced circulation type irrigation electric heater ( After being supplied to 11) and heated to a temperature lower than the saturation temperature, it is supplied to the auxiliary boiler 21 in a state of water and converted to steam, absorbed as latent heat and converted to the saturation temperature. It relates to an irrigation electric heating system for ships configured to deliver steam from a boiler (21) to a steam heater (29).
선박에서 열전달 매체로 사용하는 증기는 일반적으로 선박이 항해 중에는 추진기관의 배기로 방출되는 폐열을 회수하여 생산하고 저속운항이나 정박 중에는 추진기관의 폐열이 부족하거나 없으므로 연료유를 사용하는 보조 보일러(Donkey boiler)를 가동하여 생산한다.Steam used as a heat transfer medium in ships is generally produced by recovering waste heat emitted from the exhaust of propulsion engines while the ship is sailing, and auxiliary boilers using fuel oil (Donkey It is produced by operating a boiler).
그러나 보조 보일러를 가동하면 연료유가 하루에 약 1.5~2ton이 소모되고 연소 과정에서 발생하는 매연 등이 환경을 파괴하고 하역작업 인부와 항만에 인접한 주민이 민원을 제기할 뿐만 아니라 보일러의 버너가 점화와 소화를 반복하면서 안전사고 발생 가능성이 증가한다.However, when the auxiliary boiler is operated, about 1.5 to 2 tons of fuel oil is consumed per day, and the soot generated during the combustion process destroys the environment. As fire extinguishing is repeated, the possibility of safety accidents increases.
이를 방지하기 위하여 본 출원인은 연료유를 연소시킬 수 있는 조건이 충족되지 않을 때, 이를 대체할 수 있는 방식을 제안하고자 한다.In order to prevent this, the present applicant intends to propose a method that can replace it when the conditions for burning fuel oil are not met.
한편, 공개특허공보 특2003-0008372호에는 폐유 및 폐식용유를 이용한 대체 연료유와 그 제조방법이 기재되어 있다.On the other hand, Patent Publication No. 2003-0008372 discloses alternative fuel oil using waste oil and waste cooking oil and a manufacturing method thereof.
상기 기술은, 수집된 액상폐유와 구입한 벙커C유를 스팀배관이 설치된 원료투입조에서 50∼80℃에서 예비 가열하여, 100메쉬에서 300메쉬까지의 3중망으로 구성된 원통형여과기를 거치고(제1공정) 이 과정에서 식은 원료를 재가열하여 5㎥/시간의 처리속도를 가진 원심분리(제2공정)와 개폐 발브가 부착된 유량 조정조와 0.5㎥의 약품교반기를 통하여 액상폐유와 무기염조성물용액, 물(또는 불순물을 제거한 오폐수)을 혼합교반기에 투입하고(제3공정), 모터가 장착된 혼합교반기에서 70∼80℃의 온도와 7∼10kg/㎤의 압력상태를 유지하며 40∼60분간 교반하여 각 성분간에 이온결합이 용이하게 처리하고(제4공정), 진공펌프와 15마력의 기어모터가 장착된 유화장치에서 스크류의 회전력에 의해 처리액이 1,800∼2000rpm으로 6∼8분간 상호 마찰하도록 하고, 최종적으로 하단부의 테이퍼 형성부와 미세공을 통해 마찰과 진행속도를 억제시키고(제5공정), 품질을 향상을 위해 설계된 왕복연속교반 공정으로 제5공정을 거쳐 생산된 제품의 일부를 제4공정으로 순환시켜 3공정까지 처리된 처리유와 혼합하여 제4, 제5공정을 다시한번 거치게 하므로서 발열량의 증가와 연소시 안전한 형태의 연료유를 추출한뒤(제6공정), 추출된 연료유를 사용목적에 따라 사용 목적에 따라 선택적으로 화공약품을 추가하여 40∼50℃의 저온과 7∼10kg/㎠의 압력상태에서 30∼40분간 3차 교반을 하여(제7공정) 유수분리가 일어나지 않도록 처리하는 공정을 기재하고 있다.The above technology preheats the collected liquid waste oil and purchased bunker C oil at 50 to 80 ° C. in a raw material input tank equipped with a steam pipe, passes through a cylindrical filter composed of a triple mesh of 100 mesh to 300 mesh (first Process) In this process, the raw material cooled down is reheated, centrifugal separation (second process) with a processing speed of 5㎥ / hour, liquid waste oil and inorganic salt composition solution, Water (or wastewater from which impurities have been removed) is put into the mixing agitator (third process), and the mixing agitator equipped with a motor maintains a temperature of 70 to 80 ° C and a pressure of 7 to 10 kg / cm 3 and stirs for 40 to 60 minutes. to facilitate ionic bonding between each component (4th process), and in an emulsifying device equipped with a vacuum pump and a 15 horsepower gear motor, the treatment liquid rubs against each other at 1,800 to 2000 rpm for 6 to 8 minutes by the rotational force of the screw And, finally, through the tapered part and fine holes at the lower end, friction and progress speed are suppressed (5th process), and a part of the product produced through the 5th process is a reciprocating continuous stirring process designed to improve quality. It is circulated through the 4th process, mixed with the treated oil processed up to the 3rd process, and then passed through the 4th and 5th processes again to increase the calorific value and extract fuel oil in a safe form during combustion (process 6), and then the extracted fuel oil According to the purpose of use, depending on the purpose of use, chemical chemicals are selectively added and stirred for 30 to 40 minutes at a low temperature of 40 ~ 50 ℃ and a pressure of 7 ~ 10 kg / ㎠ (Step 7) to prevent oil-water separation. It describes the process to avoid it.
즉, 위의 기술과 같이 연료유를 대체할 수 있는 기술이 개발된 바 있으나, 이는 보조 보일러의 가동 자체를 막을 수는 없으므로, 종래 문제점의 극복이 불가능하다.That is, although a technology capable of replacing fuel oil has been developed as in the above technology, it cannot prevent the operation of the auxiliary boiler itself, so it is impossible to overcome the conventional problems.
다른 한편, 등록특허공보 제10-1707191호에는 전기히터를 이용한 선박 엔진 냉각수의 가열 및 순환시스템이 기재되어 있다.On the other hand, Patent Registration No. 10-1707191 discloses a system for heating and circulating cooling water of a ship engine using an electric heater.
상기 기술은, 선박의 운항시에는 메인엔진으로 냉각수를 공급시켜 메인엔진의 정상 가동이 가능토록 하고, 선박의 정박시에는 메인엔진으로 공급되는 냉각수를 소정의 온도로 가열하여 메인엔진 연소실린더의 열충격 손상을 방지하는 워밍작업을 수행토록 한 선박 엔진 냉각수의 가열 및 순환시스템에 관한 것으로서, 더욱 상세하게는 팽창탱크로부터 순환펌프를 거쳐 메인엔진으로 냉각수를 공급하는 공급라인상에 기존의 스팀히터 열교환기를 대신하여 전기히터 열교환기를 설치하거나, 전기히터 열교환기를 스팀히터 열교환기와 함께 병렬식으로 연결 설치하는 한편, 메인엔진을 거쳐 팽창탱크로 냉각수를 배출시키는 회수라인상에 온도제어밸브를 설치하고, 상기 온도제어밸브로부터 리턴라인을 연장시켜 순환펌프의 흡입(입구)측과 연결시키거나, 전기히터 열교환기 자체에 장착된 온도제어기를 이용하여 냉각수 온도를 직접 제어토록 함으로서, 선박의 정박시 보일러에 연료유를 공급하여 스팀을 생성시키는 기존의 엔진워밍 방식과 비교하여 연료유의 소모량과 온실가스의 발생량을 최대한으로 줄이는 한편, 메인엔진을 거쳐 배출된 냉각수의 온도조건에 맞추어 이를 팽창탱크로 회수하지 않고 순환펌프측으로 직접 공급시키는 방식으로 냉각수의 순환경로를 단축시켜 냉각수의 열손실에 따른 에너지 낭비 또한 방지할 수 있도록 한 선박 엔진 냉각수의 가열 및 순환시스템에 관한 것이다.The above technology enables normal operation of the main engine by supplying cooling water to the main engine when the ship is operating, and heats the cooling water supplied to the main engine to a predetermined temperature when the ship is docked to prevent thermal shock in the combustion cylinder of the main engine. It relates to a heating and circulation system for cooling water of a ship engine to perform a warming operation to prevent damage. Instead, an electric heater heat exchanger is installed, or the electric heater heat exchanger is connected and installed in parallel with the steam heater heat exchanger, while a temperature control valve is installed on the recovery line that discharges the cooling water to the expansion tank through the main engine, By extending the return line from the control valve and connecting it to the suction (inlet) side of the circulation pump, or by directly controlling the temperature of the cooling water using the temperature controller mounted on the electric heater heat exchanger itself, fuel oil is supplied to the boiler when the ship is docked. Compared to the existing engine warming method in which steam is generated by supplying steam, fuel oil consumption and greenhouse gas emissions are reduced to the maximum, while the circulation pump does not return it to the expansion tank according to the temperature conditions of the coolant discharged through the main engine. The present invention relates to a heating and circulation system for cooling water of a ship engine, which can reduce energy waste due to heat loss of the cooling water by shortening the circulation path of the cooling water by directly supplying the cooling water to the side.

본 발명에 따른 선박용 관수전기가열시스템은, 내연기관으로 추진하는 선박에서 저속운항이나 정박 중 절탄기에서 회수할 수 있는 열에너지가 부족하거나 없는 경우, 순환수 펌프(12)를 이용하여 관수를 강제순환식 관수전기히터(11)로 공급되어 포화온도보다 낮은 온도로 가열된 후, 물인 상태로 보조 보일러(21)로 공급되면서 증기로 변환되면서 잠열로 흡수되고 포화온도로 변환되는 과정에서 발생된 증기를 이용하여, 상기 보조 보일러(21)가 증기히터(29)로 증기를 전달할 수 있도록 하는 장점을 가진다.The irrigation electric heating system for ships according to the present invention uses a circulation water pump (12) to forcibly circulate irrigation water when there is insufficient or no thermal energy that can be recovered from the economizer during low-speed sailing or anchorage in a ship propelled by an internal combustion engine.

상기 보조 보일러(21)는 상기 연료유를 연소시키는 연료유 버너(23)를 포함하도록 구성된다.The auxiliary boiler 21 is configured to include a fuel oil burner 23 for burning the fuel oil.
상기 선박용 보일러는 상술된 바와 같이 오일류를 연소시키는 버너 시스템과 선박의 프로펠러를 구동시키기 위한 엔진으로부터 배출되는 배기가스의 폐열을 이용하는 시스템 2가지 시스템을 적용한 복합 시스템으로 구현될 수도 있다. 이러한 기술은 종래 다수 공지된 기술을 이용하는 것이므로, 구체적인 구성의 적용은 생략하여 설명할 수 있다.As described above, the ship boiler may be implemented as a complex system applying two systems, a burner system for burning oil and a system for using waste heat of exhaust gas discharged from an engine for driving a propeller of a ship. Since these technologies use a number of conventionally known technologies, the application of specific configurations can be omitted.
이때, 상기 연료유 버너(23)에 의해 연소된 연료유는 연소되면서 증기가 발생되고, 증기의 발생에 따라 보조 보일러(21)의 내측에 압력이 발생되는데, 이러한 압력의 측정을 위하여 보조 보일러(21)의 일측에는 압력센서(22)가 구성된다.At this time, the fuel oil burned by the fuel oil burner 23 is combusted and steam is generated, and as the steam is generated, pressure is generated inside the auxiliary boiler 21. To measure this pressure, the auxiliary boiler ( On one side of 21), a pressure sensor 22 is configured.
이러한 압력센서(22)의 측정값에 기반하여, 연료유 버너(23)는 연소량을 조절하도록 한다.Based on the measured value of the pressure sensor 22, the fuel oil burner 23 adjusts the amount of combustion.
이때, 연료유의 연소에 의해 발생된 증기는 보조 보일러(21)와 별도로 연결된 증기히터(29)로 공급되는데, 이를 위한 종래 통상의 기술자에 의한 파이프, 관 등의 구조를 채용할 수 있다.At this time, the steam generated by the combustion of fuel oil is supplied to the steam heater 29 connected separately to the auxiliary boiler 21, and for this purpose, a structure such as a pipe or a tube by a person skilled in the art may be employed.
여기서 상기 증기히터(29)는 선박에 사용되는 다수의 증기히터를 의미하며, 이와 같이 보조 보일러(21)로부터 증기를 공급받은 증기히터(29)에서는 증기가 응축되면서 응축수가 발생되고, 발생된 응축수는 응축수 냉각기(28)를 통과하여 냉각된 후 응축수 탱크(27)에 수용된다.Here, the steam heater 29 refers to a plurality of steam heaters used in ships, and in the steam heater 29 supplied with steam from the auxiliary boiler 21 as described above, condensate is generated as steam is condensed, and condensate is generated. After passing through the condensate cooler 28 and cooled, it is received in the condensate tank 27.
이때, 상기 응축수 탱크(27)는 보조 보일러(21)와 파이프, 호스, 관 등으로 연결되되, 연결된 일측에 급수펌프(26)를 포함하여, 응축수 탱크(27)에 수용된 응축수가 보조 보일러(21)로 순환될 수 있도록 한다.At this time, the condensate tank 27 is connected to the auxiliary boiler 21 by pipes, hoses, tubes, etc., including a feed water pump 26 on one side connected to the condensate tank 27 so that the condensate contained in the auxiliary boiler 21 ) to be cycled.
이러한 응축수는, 보조 보일러(21)의 기능에 의해 증발됨에 따라 모자라는 물을 공급하기 위한 것이다. 이때 응축수가 보조 보일러(21) 내 급수되기 위하여, 급수펌프(26)에서부터 보조 보일러(21) 사이에는 급수조절밸브(25)가 구비될 수 있다.This condensed water is to supply insufficient water as it is evaporated by the function of the auxiliary boiler 21 . In this case, a water supply control valve 25 may be provided between the water supply pump 26 and the auxiliary boiler 21 so that the condensed water is supplied to the auxiliary boiler 21 .
상기 급수조절밸브(25)는 보조 보일러(21) 일측에 구성된 수위센서(24)와 연계되어 제어되도록 구성된다.The water supply control valve 25 is configured to be controlled in conjunction with the water level sensor 24 configured on one side of the auxiliary boiler 21.
한편, 내연기관으로 추진하는 선박에서 저속운항이나 정박 중 절탄기에서 회수할 수 있는 열에너지가 부족하거나 없는 경우 보조 보일러의 연료유 버너(23)를 운전하지 않음에 특징이다.On the other hand, it is characterized in that the fuel oil burner 23 of the auxiliary boiler is not operated when there is insufficient or no thermal energy that can be recovered from the economizer during low-speed sailing or anchorage in a ship propelled by an internal combustion engine.
즉, 순환수 펌프(12)로 가압한 관수를 강제순환식 관수전기히터(11)에서 포화온도 이하로 전기히터 제어기(14)를 이용하여 가열하여 물인 상태로 압력이 보다 낮은 보조 보일러(21)로 돌아오면 관수의 일부가 증기로 바뀌면서 잠열로 흡수되고 포화온도까지 떨어진다.That is, the water pressurized by the circulation water pump 12 is heated in the forced circulation water heater 11 to below the saturation temperature using the electric heater controller 14, and the auxiliary boiler 21 has a lower pressure in the state of water. When it returns to , a part of the irrigation water turns into steam, which is absorbed as latent heat and falls to the saturation temperature.
이때 발생하는 증기를 사용하도록 한다. 또한, 상기 관수는 순환수 펌프(12)를 이용하여 지속적으로 순환되도록 할 수 있다.Use the steam generated at this time. In addition, the irrigation water can be continuously circulated using the circulation water pump 12 .
또한, 상기 강제순환식 관수전기히터(11) 일측으로는 온도센서(13)가 구비되어 강제순환식 관수전기히터(11)의 온도를 측정한다.In addition, a temperature sensor 13 is provided on one side of the forced circulation electric irrigation heater 11 to measure the temperature of the forced circulation electric irrigation heater 11 .
상기 강제순환식 관수전기히터(11)는 히터 제어기(14)에 의해 가열량이 조절되는데, 이때 상기 히터 제어기(14)는 상술된 온도센서(13) 또는 압력센서(22) 중 어느 하나 이상의 값에 기반하여 가열량을 조절하도록 한다.The forced circulation type irrigation electric heater 11 is controlled by the heater controller 14 in the amount of heating. Based on this, the amount of heating can be adjusted.
즉, 온도센서(13)의 경우, 온도센서(13)의 측정된 온도값에 기반하여 강제순환식 관수전기히터(11)에서 방출되는 열의 온도가 일정 온도를 초과하지 않도록 히터 제어기(14)가 제어하고, 압력센서(22)의 측정된 압력값에 기반하여 보조 보일러(21) 내의 압력에 기반하여 강제순환식 관수전기히터(11)의 가열량을 조절하는 것이다.That is, in the case of the temperature sensor 13, based on the measured temperature value of the temperature sensor 13, the heater controller 14 prevents the temperature of the heat emitted from the forced circulation water heater 11 from exceeding a certain temperature. and to adjust the heating amount of the forced circulation water heater 11 based on the pressure in the auxiliary boiler 21 based on the pressure value measured by the pressure sensor 22.
다른 한편, 상술된 보조 보일러(21)는 상술된 바와 같이 다수의 증기히터(29)로 증기를 공급하는데, 설계 조건에 따라서는 보조 보일러(21) 내부의 압력에 따라서, 증기가 공급될 증기히터(29)의 개수를 선택하도록 할 수 있다.On the other hand, the above-described auxiliary boiler 21 supplies steam to a plurality of steam heaters 29 as described above. Depending on the design condition, the steam heater to be supplied according to the pressure inside the auxiliary boiler 21 (29) can be selected.
즉, 후술되는 구성은 1개로 도시되어 있지만, 다수 개 구성될 수도 있고, 압력센서(22)에 기반하여 구동되는 원리이다.That is, although the configuration to be described later is shown as one, it may be configured in multiple configurations, and is a principle that is driven based on the pressure sensor 22 .
