본 발명은 기관(10)과 배기덕트(15)를 갖춘 선박의 습식 스크러버 시스템에 관하여 제안한다. 선박의 기관(10)은 주기 외에 보기를 포함할 수 있으며, 배기덕트(15)의 상류 측에서 배기가스를 스크러버로 보낸다. 개방형의 습식 스크러버를 대상으로 하지만 이에 한정되지 않고 개방형과 폐쇄형을 포함하는 하이브리드형의 스크러버에도 적용이 가능하다.The present invention proposes a wet scrubber system of a ship with an engine (10) and an exhaust duct (15). The engine 10 of the vessel may comprise a bogie in addition to the cycle, and sends the exhaust gas to the scrubber upstream of the exhaust duct 15. Although open wet scrubber is targeted, it is possible to apply to hybrid scrubber including but not limited to open type and closed type.

본 발명에 따르면 스크러버(20)가 상기 배기덕트(15)에서 인입되는 배기가스에 세정수관(21)과 배출수관(27)으로 유동하는 해수를 분사하는 구조를 이르고 있다. 도 1을 참조하면, 배기가스는 스크러버(20)의 측면 하부에서 상면으로 유동하고, 해수는 스크러버(20)의 측면 상부에서 하면으로 분사된 상태로 유동한다. 세정수관(21)은 선체 외부나 밸러스트 탱크 등에서 해수를 취수하여 스크러버(20)로 보내도록 급수펌프(22)와 함께 설치된다. 배출수관(27)은 스크러버(20)에서 배기가스의 미세먼지를 비롯한 분진, 황산화물, 질소산화물 등을 흡수한 해수(폐수)를 배출하도록 설치된다.According to the present invention, the scrubber 20 achieves a structure in which seawater flowing into the washing water pipe 21 and the discharge water pipe 27 flows into the exhaust gas introduced from the exhaust duct 15. Referring to FIG. 1, the exhaust gas flows from the lower side of the scrubber 20 to the upper surface, and the seawater flows from the upper side of the scrubber 20 to the lower surface. The washing water pipe 21 is installed together with the water supply pump 22 to collect seawater from the outside of the hull or the ballast tank and send it to the scrubber 20. The discharge water pipe 27 is installed to discharge seawater (waste water) that absorbs dust, sulfur oxides, nitrogen oxides, etc., including fine dust of the exhaust gas from the scrubber 20.

한편, 도 1을 참조하면, 세정수관(21)을 통하여 스크러버(20)에 유입되는 해수 유량의 변동폭이 큰 경우 세정수관(21) 상에 세정수조(23)를 더 설치하는 것이 바람직하다.Meanwhile, referring to FIG. 1, when the fluctuation range of the seawater flow rate flowing into the scrubber 20 through the washing water pipe 21 is large, it is preferable to further install the washing water tank 23 on the washing water pipe 21.

본 발명의 세부 구성에 의하면, 상기 스크러버(20)에서 배출되는 해수의 오염도를 저감하기 위한 폐수처리기(30)를 더 구비하고, 상기 폐수처리기(30)는 수분분리부(32), 중화처리부(34), 탈황처리부(36)를 포함한다.According to a detailed configuration of the present invention, the wastewater treatment unit 30 for reducing the pollution degree of the seawater discharged from the scrubber 20, the wastewater treatment unit 30 is a water separation unit 32, the neutralization treatment unit ( 34), and a desulfurization treatment section 36.

도 1을 참조하면, 배출수관(27) 상에서 수차발전기(41)의 하류측에 폐수처리기(30)가 설치된 상태를 예시한다. 개방식 스크러버 시스템에 있어서 배출수관(27)으로 배출되는 해수를 폐수처리기(30)를 거쳐 방류하면 해양 오염의 가능성을 축소하는데 유리하다. Referring to FIG. 1, a wastewater processor 30 is installed downstream of the aberration generator 41 on the discharge water pipe 27. In the open scrubber system, the discharge of seawater discharged to the discharge water pipe 27 through the wastewater processor 30 is advantageous in reducing the possibility of marine pollution.

도 2를 참조하면, 폐수처리기(30)는 수분분리부(32), 중화처리부(34), 탈황처리부(36) 중 하나 또는 복수로 적용한다. 수분분리부(32)는 폐수에서 분진 등의 고형분을 걸러내고 수분만 유동시킨다. 수분분리부(32)로서 여과 방식, 원심분리 방식 등에서 선택 가능하다. 중화처리부(34)는 폐수가 선외로 방출되거나 스크러버(20)로 재순환하기 적합한 pH 6.5 이상으로 중화한다. 중화처리부(34)로서 물리ㆍ화학적 방식이 적용되지만 생물학적 방식을 포함할 수 있다. 탈황처리부(36)는 폐수중의 유독성 황산화물을 분리한다. 탈황처리부(36)로서 화학적 산화방식, 분리방식, 침전방식 등에서 선택 가능하다.Referring to FIG. 2, the wastewater treatment device 30 is applied to one or more of the water separation unit 32, the neutralization treatment unit 34, and the desulfurization treatment unit 36. The water separator 32 filters solids such as dust from the waste water and flows only moisture. As the water separator 32, it can be selected from a filtration method, a centrifugal separation method, and the like. The neutralization unit 34 neutralizes the wastewater to pH 6.5 or higher suitable for discharge to the shipboard or recycle to the scrubber 20. Although the physicochemical method is applied as the neutralization processing part 34, it may include a biological method. The desulfurization treatment unit 36 separates toxic sulfur oxides in the wastewater. The desulfurization treatment unit 36 can be selected from chemical oxidation, separation, precipitation, and the like.

또한, 본 발명에 따르면 가동수단이 상기 배출수관(27) 상에 설치되는 수차발전기(41)에서 생성된 전력으로 세정수관(21)에 설치된 급수펌프(22)의 동력을 분담하는 구조이다. 가동수단은 스크러버(20)로 인하여 유발되는 에너지를 활용하여 스크러버 시스템의 효율을 높인다. 가동수단의 일예로 배출수관(27) 상에 수차발전기(41)를 설치할 수 있다. 수차발전기(41)의 방식은 배출수관(27)의 낙차와 유량을 고려하여 결정한다. Further, according to the present invention, the movable means shares the power of the water supply pump 22 installed in the washing water pipe 21 with the electric power generated by the aberration generator 41 installed on the discharge water pipe 27. The movable means utilizes energy generated by the scrubber 20 to increase the efficiency of the scrubber system. As an example of the movable means, the aberration generator 41 may be installed on the discharge water pipe 27. The method of the aberration generator 41 is determined in consideration of the drop and the flow rate of the discharge water pipe (27).

한편, 도시에는 생략하나 필요에 따라 세정수관(21)의 세정수조(23)와 같은 별도의 수조를 배출수관(27)의 상류측에 설치할 수 있다.On the other hand, although not shown in the drawing, a separate water tank such as the washing water tank 23 of the washing water pipe 21 may be provided upstream of the discharge water pipe 27 as necessary.

본 발명의 세부 구성에 의하면, 상기 배출수관(27)과 세정수관(21) 사이에 해수 재순환을 위해 연결되는 환수수관(25), 환수수관(25)과 배출수관(27)의 교차점에서 해수를 펌핑하도록 설치되는 수격펌프(43)를 더 구비한다.According to the detailed configuration of the present invention, the seawater at the intersection of the return water pipe 25, the return water pipe 25 and the discharge water pipe 27 is connected between the discharge water pipe 27 and the washing water pipe 21 for seawater recycling. It is further provided with a water hammer pump 43 is installed to pump.

도 1을 참조하면, 배출수관(27) 상에서 폐수처리기(30)의 하류측에 수격펌프(43)가 설치되고 수격펌프(43)에서 상류의 세정수관(21) 측으로 환수수관(25)이 연결된 상태를 예시한다. 폐수처리기(30)를 거쳐 정화된 폐수(정화수)가 수격펌프(43)와 환수수관(25)으로 유입된다. 수격펌프(43)는 배출수관(27)을 유동하는 정화수의 낙차 에너지를 동력원으로 환수수관(25)을 통한 일부 정화수의 펌핑과 재순환을 유발한다. 세정수관(21)에서 스크러버(20)로 투입되는 정화수의 양만큼 스크러빙 워터(해수)를 절감할 수 있다. Referring to FIG. 1, a water hammer pump 43 is installed downstream of the wastewater processor 30 on the discharge water pipe 27, and a return water pipe 25 is connected to the washing water pipe 21 upstream from the water hammer pump 43. Illustrate the state. The purified wastewater (purified water) is introduced into the water hammer pump 43 and the return water pipe 25 through the wastewater processor 30. The water hammer pump 43 causes pumping and recirculation of some purified water through the return pipe 25 as a power source using the free energy of the purified water flowing through the discharge water pipe 27. The scrubbing water (sea water) can be reduced by the amount of purified water introduced into the scrubber 20 from the washing water pipe 21.

본 발명의 변형예로서, 상기 가동수단은 배출수관(27) 상에서 열전소자를 기반으로 전력을 생성하는 폐열회수기(45)를 더 구비한다.As a variant of the invention, the movable means further comprises a waste heat recovery 45 for generating electric power based on the thermoelectric element on the discharge water pipe 27.

도 1을 참조하면, 배출수관(27)에서 스크러버(20)에 인접하여 폐열회수기(45)가 설치된 상태를 예시한다. 폐열회수기(45)는 폐수의 열에너지를 이용하여 열전소자에서 전력을 생산하는 외에 여타 시스템의 가온을 위한 열원으로 활용될 수 있다. 폐열회수기(45)의 열전소자는 폐수와 접하는 고온블록과 대기와 접하는 저온블록 사이에 배치되고, 생성되는 전력을 이용하여 수차발전기(41)와 마찬가지로 급수펌프(22)의 동력을 분담한다. 물론 경우에 따라서는 급수펌프(22) 외에 폐수처리기(30)의 동력을 분담할 수도 있다.Referring to FIG. 1, a waste heat recovery unit 45 is illustrated adjacent to the scrubber 20 in the discharge water pipe 27. Waste heat recoverer 45 may be used as a heat source for heating other systems in addition to producing power from the thermoelectric element using the heat energy of the waste water.

In some cases, of course, the power of the wastewater processor 30 may be shared in addition to the water supply pump 22.

또한, 본 발명에 따르면 제어수단이 상기 스크러버(20)와 가동수단을 설정된 알고리즘으로 제어하는 구조이다. 도 2에서, 제어수단의 제어기(52)를 중심으로 하는 회로 연결을 예시한다. 제어기(52)는 스크러버(20) 외에 폐수처리기(30), 수차발전기(41) 등과 관련된 제어 알고리즘을 수행한다.In addition, according to the present invention, the control means is configured to control the scrubber 20 and the movable means by a set algorithm. In Fig. 2, a circuit connection centering on the controller 52 of the control means is illustrated. In addition to the scrubber 20, the controller 52 performs control algorithms related to the wastewater processor 30, the aberration generator 41, and the like.

본 발명의 세부 구성에 의하면, 상기 제어수단은 마이컴 회로로 구성되는 제어기(52), 기관(10)의 부하변동을 검출하는 부하검출기(54), 해수의 유동량 변화를 검출하는 유량검출기(56), 세정수관(21)의 해수 유량을 조절하는 유량조절기(58)를 구비한다.According to the detailed configuration of the present invention, the control means includes a controller 52 composed of a microcomputer circuit, a load detector 54 for detecting a load change of the engine 10, and a flow detector 56 for detecting a change in the flow amount of seawater. And a flow controller 58 for adjusting the seawater flow rate of the washing water pipe 21.

도 2를 참조하면, 마이컴 회로로 구성된 제어기(52)의 입력인터페이스에 부하검출기(54), 유량검출기(56) 등이 연결되고, 출력인터페이스에 급수펌프(22), 폐수처리기(30), 수차발전기(41), 유량조절기(58) 등이 연결된다. 제어기(52)는 기관(10)에 설치된 부하검출기(54)의 신호로 배기가스의 처리량을 연산하고, 세정수관(21)과 환수수관(25)에 설치된 유량검출기(56)의 신호로 해수의 유동량을 연산한다. 유량조절기(58)는 세정수관(21)에 설치되고 급수펌프(22)와 연계하여 스크러버(20)로 투입되는 해수량을 조절한다.Referring to FIG. 2, a load detector 54, a flow rate detector 56, and the like are connected to an input interface of a controller 52 composed of a microcomputer circuit, and a feed water pump 22, a wastewater processor 30, and aberration are connected to an output interface. The generator 41, the flow regulator 58, and the like are connected. The controller 52 calculates the throughput of the exhaust gas by the signal of the load detector 54 installed in the engine 10, and calculates the throughput of the seawater by the signal of the flow rate detector 56 installed in the washing water pipe 21 and the return water pipe 25. Calculate the flow rate. The flow controller 58 is installed in the washing water pipe 21 and adjusts the amount of seawater introduced into the scrubber 20 in association with the water supply pump 22.

작동의 일예로서, 제어기(52)는 스크러버(20)로 유입되는 배기가스의 처리량에 대응하여 급수펌프(22) 및 유량조절기(58)로 스크러버(20)에 투입되는 해수 유량을 단계적으로 조절하는 동시에 환수수관(25)의 해수(정화수) 유량에 대응하여 급수펌프(22) 및 유량조절기(58)를 제어하여 세정수관(21)으로 유입되는 해수 유량의 미소한 증감도 유발한다. 이 과정에서 수차발전기(41), 폐열회수기(45)에서 생성되는 전력을 이용하므로 에너지 효율 향상을 도모한다.As an example of operation, the controller 52 adjusts the flow rate of the seawater introduced into the scrubber 20 by the feed water pump 22 and the flow regulator 58 in response to the throughput of the exhaust gas flowing into the scrubber 20. At the same time, the water supply pump 22 and the flow regulator 58 are controlled in response to the seawater (purified water) flow rate of the return water pipe 25 to cause a slight increase and decrease of the seawater flow rate flowing into the washing water pipe 21. In this process, since the power generated by the aberration generator 41 and the waste heat recovery machine 45 is used, energy efficiency is improved.
