이러한 기반 인프라 하에서, 제어기(43) 측에서는 환원제 공급 유로(23) 상에 배치된 센서(24), SCR 반응기(30)의 후단에 배치된 센서(26), 배기가스 유통라인(15)(16) 상에 배치된 밸브(17,18), 환원제 공급 유로(44) 상에 배치된 밸브(42), 용수 공급 유로(29) 상에 배치된 밸브(40), 가열공기 유통라인(21) 상에 배치된 밸브(20) 등과 통신을 취하면서, 각 센서(24,26) 측으로부터 전송되는 감지 값(예컨대, SCR 반응기(30)를 통과한 정화 배기가스에 포함된 유해물질의 값, 환원제 가수분해 챔버로부터 공급되는 환원제의 온도 값 등)에 따라, 각 밸브(17,18,42,40,20)를 개폐시킴으로써, 엔진(11)으로부터 출력되는 배기가스의 유통 패턴, 환원제의 공급/유통 패턴, 가열공기의 공급/유통 패턴 등을 적절하게 조절하는 역할을 수행하게 된다(물론, 상술한 각 유통라인, 유로, 센서, 밸브 등의 개수, 위치, 형태 등은 상황에 따라, 다양한 변형을 이룰 수 있다).The sensor 24 disposed on the reducing agent supply passage 23, the sensor 26 disposed at the rear end of the SCR reactor 30, the exhaust gas distribution lines 15 and 16, A valve 42 disposed on the reducing agent supply passage 44, a valve 40 disposed on the water supply passage 29, and a valve 42 disposed on the heated air distribution line 21 (For example, the value of the harmful substances contained in the purified exhaust gas passing through the SCR reactor 30, the value of the reducing agent hydrolysis, and the like) while communicating with the disposed valves 20 and the like, The distribution pattern of the exhaust gas output from the engine 11, the supply / distribution pattern of the reducing agent, the flow rate of the reducing agent, and the flow rate of the reducing agent are controlled by opening and closing the valves 17, 18, (For example, each of the above-described distribution lines, flow paths, sensors, valves, and the like) The number, position, shape, etc. of the elements can be varied depending on the situation).

한편, 이러한 종래의 체제 하에서, 배기가스 유통라인(16)을 통해 유입되는 배기가스, 환원제 분사기(25)를 통해 분사되는 환원제, 가열공기 유통라인(21)을 통해 유입되는 가열공기 등은 SCR 반응기(30)의 입구(I)에 한데 모여 SCR 촉매(32) 측으로 흘러 들어가는 패턴을 보이게 된다.On the other hand, under such a conventional system, the exhaust gas flowing through the exhaust gas circulating line 16, the reducing agent injected through the reducing agent injector 25, the heated air introduced through the heated air circulating line 21, (I) of the SCR catalyst (30) and flows into the SCR catalyst (32) side.

물론, 이 상황 하에서, 배기가스, 환원제, 가열공기 등이 SCR 반응기(30)로 흘러 들어가기 이전에, 배기가스가 가지는 열 에너지, 가열공기가 가지는 열 에너지 등을 적절하게 융합하는 절차, 이렇게 융합된 열 에너지를 토대로, 환원제를 적절히 분해는 절차 등은 전체적인 SCR 반응기(30)의 정화성능을 결정짓는데 있어서, 매우 중요한 변수로 작용하게 된다.Of course, in this situation, a procedure for appropriately fusing the heat energy of the exhaust gas, the heat energy of the heated air, and the like before the exhaust gas, the reducing agent, the heated air, and the like flow into the SCR reactor 30, The process of decomposing the reducing agent appropriately based on thermal energy is a very important parameter in determining the purifying performance of the overall SCR reactor 30. [

이는, 만약, 배기가스가 가지는 열 에너지, 가열공기가 가지는 열 에너지 등이 적절히 융합되지 못하여, 이들 간에 적정 수준의 온도상승이 이루어지지 못하게 되고, 그 결과로, 환원제의 분해 역시 적절하게 이루어지지 못하게 되는 경우, SCR 반응기(30) 측에서는 자가 성능수행 보증온도의 충족을 위한 열 에너지의 지원은 물론, 적정 수준으로 분해된 환원제까지도 전혀 수급 받지 못하게 되며, 결국, 유해물질(예컨대, 질소산화물)의 환원 처리절차를 진행하는데 있어서, 큰 어려움을 겪을 수밖에 없게 되기 때문이다.This is because, if the heat energy of the exhaust gas and the heat energy of the heated air are not properly fused, an appropriate level of temperature rise can not be achieved between them, and as a result, the decomposition of the reducing agent , The SCR reactor 30 side can not receive a sufficient amount of the decomposed reducing agent as well as the support of thermal energy for meeting the self-performance guarantee temperature, and consequently, the reduction of the harmful substance (for example, nitrogen oxides) This is because, in proceeding with the processing procedure, there is a great difficulty.

그러나, 상황이 이러함에도 불구하고, 종래의 경우, SCR 반응기(30)의 입구(I)에는 배기가스가 가지는 열 에너지, 가열공기가 가지는 열 에너지 등을 적절히 융합하고, 이를 토대로, 환원제를 효과적으로 분해하기 위한 어떠한 구성요소도 배치되어 있지 아니하였기 때문에, 선박 운영주체 측에서는 공기가열기(19)에 의한 가열공기의 추가 공급에도 불구하고, SCR 반응기(30)의 정화성능을 향상시키는데 있어서, 큰 어려움을 겪을 수밖에 없었으며, 결국, 그에 따른 유/무형의 피해를 고스란히 감수할 수밖에 없었다.However, in spite of this situation, in the conventional case, the inlet (I) of the SCR reactor 30 is appropriately fused with the thermal energy of the exhaust gas and the thermal energy of the heated air, There is a great difficulty in improving the purifying performance of the SCR reactor 30 in spite of the additional supply of the heated air by the air heater 19 at the ship operator's side I was forced to suffer, and in the end, I was forced to bear the damage of the tangible / intangible.

Under this situation, the reducing agent storage tank 128 side stores a reducing agent (for example, urea) to be supplied to the reducing agent hydrolysis chamber 122 side and the water reducing tank 127 side is connected to the reducing agent hydrolysis chamber 122 side And stores the water to be supplied.

이 경우, 환원제 공급 유로(144) 측에서는 환원제 저장탱크(128)와 환원제 가수분해 챔버(122)를 상호 연결함으로써, 환원제 저장탱크(128)에 저장되어 있던 환원제가 환원제 가수분해 챔버(122)로 정상 전달될 수 있도록 지원하는 역할을 수행하게 되며, 용수 공급 유로(129) 측에서는 용수 저장탱크(127)와 환원제 공급 유로(144)를 상호 연결함으로써, 용수 저장탱크(127)에 저장되어 있던 용수가 환원제 가수분해 챔버(122)로 정상 전달될 수 있도록 지원하는 역할을 수행하게 된다(물론, 용수 공급 유로(129)는 환원제 가수분해 챔버(122)와 직접 연결될 수도 있다).The reducing agent storage tank 128 and the reducing agent hydrolysis chamber 122 are connected to each other so that the reducing agent stored in the reducing agent storage tank 128 is returned to the reducing agent hydrolysis chamber 122 The water storage tank 127 and the reducing agent supply flow passage 144 are connected to each other so that the water stored in the water storage tank 127 is supplied to the reducing agent supply passage 129. [ (The water supply flow path 129 may be directly connected to the reducing agent hydrolysis chamber 122). In this case, the water supply channel 129 may be directly connected to the reducing agent hydrolysis chamber 122.

이때, 공기가열기(119) 측에서는 가열공기 유통라인(121)을 매개로, SCR 반응기(130)와 연결되는 구조를 취하면서, 외부로부터 공급되는 연료 및 공기를 토대로 고온의 가열공기를 생성하고, 생성 완료된 가열공기를 가열공기 유통라인(121)을 통해 SCR 반응기(130) 측으로 공급함으로써, SCR 챔버(131) 내의 SCR 촉매(132)가 고온의 열 에너지 지원을 받으면서, 좀더 효과적인 유해물질 정화절차를 진행할 수 있도록 지원하는 역할을 수행하게 된다.At this time, on the side of the air heat exchanger 119, the high-temperature heated air is generated on the basis of the fuel and air supplied from the outside, while being connected to the SCR reactor 130 through the heated air distribution line 121, The SCR catalyst 132 in the SCR chamber 131 is supplied with high temperature thermal energy by supplying the generated heated air to the SCR reactor 130 side through the heated air circulation line 121 to perform a more effective harmful substance purification procedure And to support the process.

이러한 기반 인프라 하에서, 제어기(143) 측에서는 환원제 공급 유로(123) 상에 배치된 센서(124), SCR 반응기(130)의 후단에 배치된 센서(126), 배기가스 유통라인(115)(116) 상에 배치된 밸브(117,118), 환원제 공급 유로(144) 상에 배치된 밸브(142), 용수 공급 유로(129) 상에 배치된 밸브(140), 가열공기 유통라인(121) 상에 배치된 밸브(120) 등과 통신을 취하면서, 각 센서(124,126) 측으로부터 전송되는 감지 값(예컨대, SCR 반응기(130)를 통과한 정화 배기가스에 포함된 유해물질의 값, 환원제 가수분해 챔버로부터 공급되는 환원제의 온도 값 등)에 따라, 각 밸브(117,18,42,40,20)를 개폐시킴으로써, 엔진(111)으로부터 출력되는 배기가스의 유통 패턴, 환원제의 공급/유통 패턴, 가열공기의 공급/유통 패턴 등을 적절하게 조절하는 역할을 수행하게 된다(물론, 상술한 각 유통라인, 유로, 센서, 밸브 등의 개수, 위치, 형태 등은 상황에 따라, 다양한 변형을 이룰 수 있다).A sensor 126 disposed at the rear end of the SCR reactor 130, an exhaust gas distribution line 115, and an exhaust gas distribution line 116 are disposed on the side of the controller 143, A valve 142 disposed on the reducing agent supply passage 144; a valve 140 disposed on the water supply passage 129; a valve 140 disposed on the heated air distribution line 121; (For example, the value of the harmful substances contained in the purified exhaust gas that has passed through the SCR reactor 130, the value of the harmful substances supplied from the reducing agent hydrolysis chamber, etc.) transmitted from the sensors 124 and 126 while communicating with the valves 120 and the like The distribution pattern of the exhaust gas output from the engine 111, the supply / distribution pattern of the reducing agent, the supply of the heated air, and the like are performed by opening and closing the valves 117, 18, / Distribution patterns, etc. (Of course, the above-described distribution lines, With a sensor, the number of valves, etc., the position, shape, etc. depending on the circumstances, can achieve a wide range of variants).

한편, 이러한 본 발명의 체제 하에서, 배기가스 유통라인(116)을 통해 유입되는 배기가스, 환원제 분사기(125)를 통해 분사되는 환원제, 가열공기 유통라인(121)을 통해 유입되는 가열공기 등은 SCR 반응기(130)의 입구(I)에 한데 모여 SCR 촉매(132) 측으로 흘러 들어가는 패턴을 보이게 된다.The exhaust gas flowing through the exhaust gas distribution line 116, the reducing agent injected through the reducing agent injector 125, the heated air introduced through the heated air circulation line 121, etc., A pattern that collects at the inlet I of the reactor 130 and flows into the SCR catalyst 132 side is shown.

물론, 이 상황 하에서도, 배기가스, 환원제, 가열공기 등이 SCR 반응기(130)로 흘러 들어가기 이전에, 배기가스가 가지는 열 에너지, 가열공기가 가지는 열 에너지 등을 적절하게 융합하는 절차, 이렇게 융합된 열 에너지를 토대로, 환원제를 적절히 분해는 절차 등은 전체적인 SCR 반응기(130)의 정화성능을 결정짓는데 있어서, 매우 중요한 변수로 작용하게 된다.Of course, even in this situation, a procedure of appropriately fusing the heat energy of the exhaust gas, the heat energy of the heated air, etc., before the exhaust gas, the reducing agent, the heated air, etc. flow into the SCR reactor 130, The process of decomposing the reducing agent appropriately based on the heat energy is a very important variable in determining the purifying performance of the entire SCR reactor 130.

특히, 앞서 언급한 바와 같이, 상기 배기 리시버(114)로부터 배출되는 배기가스는 터보 차저(113)를 거치지 않아, 그 온도가 매우 높기 때문에, 상술한 본 발명의 또 다른 구현환경 하에서, 선박 운영주체 측에서는 해당 배기가스만으로도 공기가열기(119) 내부의 온도를 손쉽게 상승시키면서, 불필요한 연료의 소모를 효과적으로 최소화시킬 수 있게 된다. In particular, as mentioned above, since the exhaust gas discharged from the exhaust receiver 114 does not pass through the turbocharger 113 and the temperature thereof is very high, under the above-described another implementation environment of the present invention, The temperature of the inside of the air heat exchanger 119 can be easily raised by the exhaust gas alone, and unnecessary fuel consumption can be effectively minimized.
