본 발명은 열기관 특히 화력발전소 등의 산업용 보일러에서의 연소 과정에서 발생 되어 배출되는 연소가스내 포함되어 있는 이산화탄소(CO2)를 효과적으로 제거하기 위한 시스템에 관한 것으로, 상세하게는 반응조측으로 연소가스가 유입되도록 하고, 그 반응조내에 수산화칼슘(Ca(OH)2), 산화마그네슘(MgO), 수산화나트륨(NaOH), 염료 등을 배합하여서 되는 이산화탄소 제거용 조성물 투입에 의해 상기 반응조측으로 유입되는 연소가스와 이산화탄소 제거용 조성물간 반응이 일어나도록 하므로서, 반응이 완료되어 반응조의 상단측 필터를 통해 필터링 된 후 외부로 이산화탄소가 제거되어 정화된 상태의 연소가스가 배출되는 일련의 과정을 거치도록 하는 연소가스의 이산화탄소 배출 제거 시스템에 관한 것이다.The present invention relates to a system for effectively removing carbon dioxide (CO 2 ) contained in the combustion gas generated during the combustion process in an industrial boiler such as a thermal power plant, particularly a thermal power plant, and more specifically, combustion gas flows into the reaction tank. And the combustion gas and carbon dioxide removal introduced into the reaction tank by the addition of a composition for removing carbon dioxide by mixing calcium hydroxide (Ca (OH) 2 ), magnesium oxide (MgO), sodium hydroxide (NaOH), dyes and the like in the reaction tank. The reaction between the two composition for the reaction occurs, the reaction is completed and filtered through the filter on the upper side of the reaction tank and the carbon dioxide is discharged to the outside to go through a series of processes in which the combustion gas of the purified state is discharged Relates to a removal system.

열기관이라 함은, 연료의 연소를 통해 열 에너지를 발생시켜 그 발생된 열 에너지의 일정량을 역학적 일에너지로 변환시킨 다음, 나머지의 열 에너지는 방출되는 것을 의미하는 것으로서 일반적으로 내연기관, 외연기관은 물론 보일러 등이 포함되어 일컬어지고 있다. Heat engine means heat energy generated by combustion of fuel, converts a certain amount of heat energy into mechanical work energy, and then the remaining heat energy is released. Generally, internal combustion engine and external combustion engine Of course, boilers are included.

이러한 열기관 중 보일러, 예를 들면 화력 발전용 보일러 등 산업용 보일러에서의 연소 가스 처리를 위해서 채택되는 시스템류의 하나로 질소 산화물(NOX)을 제거하기 위한 탈질(脫窒) 장치와 매진을 제거하기 위한 전기 집진기 및 황산화물(SO2)를 제거하기 위한 탈황 장치 등이 있다. Among these heat engines, one of the systems used for the treatment of combustion gases in industrial boilers, such as boilers for thermal power generation, is a denitrification apparatus for removing nitrogen oxides (NO X ) and for removing dust. And a desulfurization apparatus for removing an electrostatic precipitator and sulfur oxide (SO 2 ).

이러한 장치류의 경우에는 주로 연소배기가스를 탈질 시킨 후 암모니아에 의해 탈황시키고, 탈황 후에 얻은 배수 또는 집진회를 세정한 배수를 탈산칼슘을 사용하여 여과하고 그 여액의 pH를 조정하여 이산화탄소 및 탄산수용액을 가한 후 응집제를 첨가하고, 고형분을 침강 분리시켜 상징액으로부터 암모니아를 회수하되, 그 회수되는 암모니아를 탈질 후 가스에 첨가하여 연소배기가스를 처리하는 과정을 거치고 있다.In the case of such apparatus, the combustion exhaust gas is mainly denitrated and then desulfurized by ammonia, and the wastewater obtained after desulfurization or the wastewater washed with dust collection is filtered using calcium deoxidation and the pH of the filtrate is adjusted to obtain carbon dioxide and carbonated aqueous solution. After addition, a flocculant is added, solids are sedimented and separated to recover ammonia from the supernatant, and the recovered ammonia is added to the gas after denitrification to process combustion exhaust gas.

그러나, 이러한 방법 또는 시스템의 경우 연소가스내 포함되어 있는 이산화탄소의 효과적 제거가 어려움은 물론, 배수 과정에서 오히려 수질 오염이 증대될 수 있는 가능성이 존재한다.However, in the case of such a method or system, the effective removal of carbon dioxide contained in the combustion gas is difficult, as well as the possibility that water pollution may be increased in the drainage process.

본 발명에서 지칭하는 이산화탄소 제거용 액상 조성약제는 상기한 각 성분의 성분혼합비에 따라 얻게 되는 약제를 의미하는 것으로서, 본 명세서에서 약제라 지 칭하는 것은 전술한 이산화탄소 제거용 액상 조성약제를 의미한다.Liquid composition for removing carbon dioxide referred to in the present invention means a drug obtained according to the component mixing ratio of each of the above components, the term "medicine" refers to the liquid composition for removing carbon dioxide described above.

상기 송풍수단(100)은 화력 발전소 등의 산업용 보일러(미도시)에서 연료를 연소하여 열에너지를 얻은 후 배출되는 배출가스(본 발명에서는 연소가스라 통칭한다) 즉 연소가스를 본 발명의 반응조(200)측으로 유도, 유입하기 위한 수단으로 제공된다.The blowing means 100 is a discharge gas (generally referred to as combustion gas in the present invention) that is discharged after the combustion of fuel in an industrial boiler (not shown) such as a thermal power plant to obtain thermal energy, that is, the combustion gas of the present invention 200 It is provided as a means for induction and inflow to the side.

이와 같은 송풍수단(100)은 도면에서 보는 바와 같이, 송풍휀과 반응조(200)를 연결하여 상기한 연소가스를 반응조(200) 내부로 유입하기 위한 연결부(110)를 채택하게 되는데, 상기 연결부(110)는 상기 송풍수단(100)의 메인관(120)과 직교 연결되는 헤더관(130)을 형성하고, 상기 헤더관(130)으로부터 다수개의 분기관(131)이 각각 연결 돌출되며 반응조(200) 내부를 횡단 관통하되, 상기 각 하나의 분기관(131)마다 수직상으로 각각 다수개 연결되는 침수관(132)을 형성하여 반응조(200) 내부에 저장되는 약제 내부로 침수되도록 하였다.As shown in the drawing, the blowing means 100 is connected to the blowing fan and the reaction tank 200 to adopt a connecting portion 110 for introducing the combustion gas into the reaction tank 200, the connection portion ( 110 forms a header tube 130 that is orthogonally connected to the main tube 120 of the blowing means 100, a plurality of branch pipes 131 are respectively protruded from the header tube 130 and the reaction tank 200 ) To penetrate the inside, so that each one of the branch pipes 131 vertically formed a plurality of immersion pipes 132 connected to each other to be immersed into the drug stored in the reaction tank 200.

즉, 상기 송풍수단(100)으로부터 플렌지 이음에 의해 연결되는 메인관(120)이 동일 면적을 이루며 연결된 후, 상기 메인관(120)과 직교 방향으로 연결되는 헤더관(130)을 구비하였다.That is, after the main pipe 120 connected by the flange joint from the blowing means 100 to form the same area, and provided with a header pipe 130 connected in a direction orthogonal to the main pipe 120.

상기 헤더관(130)과 메인관(120) 내부를 각각 유동하는 유체의 속도와 유량은 상호 동일하게 설계되어야 할 것이다.The speed and flow rate of the fluid flowing through the header tube 130 and the main tube 120, respectively, should be designed to be the same.

한편, 상기 헤더관(130)으로부터 각각 별도로 연결되는 분기관(131)을 형성하여, 반응조(200) 내부측을 관통하며 형성되도록 하였다.On the other hand, by forming a branch pipe 131 connected to each from the header tube 130 separately, so as to penetrate the inner side of the reaction tank 200.

여기서 상기 분기관(131)은 도면에서 보는 바와 같이 그 직경이 헤더관(130) 으로부터 멀어질수록 단계적으로 작게 형성되는 것이 바람직하다.In this case, as shown in the drawing, the branch pipe 131 is preferably smaller in size as the diameter moves away from the header pipe 130.

즉, 송풍수단(100)으로부터 공급되는 연소가스의 유체압력과 유량 및 유속이 메인관(120)과 헤더관(130)을 통과할 때는 물론이고 상기한 분기관(131) 말단까지 동일하게 유동되며 공급되어야, 반응조(200) 내부에 공급 저장되는 약제와의 반응 효과를 증대 시킬 수 있기 때문이다.That is, the fluid pressure, the flow rate and the flow rate of the combustion gas supplied from the blowing means 100 is equally flowed to the end of the branch pipe 131 as well as passing through the main pipe 120 and the header pipe 130. This is because the supply effect, it is possible to increase the reaction effect with the drug is supplied and stored in the reactor (200).

아울러 상기 각각의 분기관(131) 전체에 걸쳐 그 하단측으로 각각 등간격 이격되며 직교형태로 연결된 후 반응조(200)내 저장되는 액상 약제의 내부로 침수될 수 있도록 침수관(132)을 각각 연결 구비한다.In addition, the submerged pipe 132 is connected to each of the branch pipes 131 to the bottom side, and are spaced at equal intervals and connected in an orthogonal shape so that they can be immersed into the liquid medicine stored in the reaction tank 200. do.

여기서의 상기 각 침수관(132)은 동일한 직경으로 이루어진다.Here, each of the submerged pipes 132 has the same diameter.

이와 같이, 송풍수단(100)의 동작에 의해 보일러 내부에서 연소 되어 배출되는 연소가스는 상기 연결부(110)의 메인관(120)에서 헤더관(130)측으로 유도된 후 그 헤더관(130)으로부터 각각 분기되는 분기관(131)을 따라 이동되면서 각 분기관(131) 하방으로 직교 연결되는 침수관(132)을 통해, 반응조(200)에 저장되는 약제내부에 침수되어, 연소가스가 침수관(132)측으로 배출되면서 약제와 반응하도록 하는 것이다.In this way, the combustion gas discharged by combustion in the boiler by the operation of the blowing means 100 is guided to the header tube 130 side from the main tube 120 of the connecting portion 110 from the header tube 130 The submerged pipes are immersed in the chemicals stored in the reaction tank 200 through the submerged pipes 132 orthogonally connected downward to each branch pipe 131 while moving along the branch pipes 131 which are branched, and the combustion gas is submerged in the pipe ( 132) is to be reacted with the drug while being discharged to the side.

이때의 반응은 수산화칼슘(Ca(OH)2)과 이루어지는 것으로 그 반응식은 다음과 같다.At this time, the reaction is made with calcium hydroxide (Ca (OH) 2 ), the reaction formula is as follows.

Ca(OH)2 + CO2 -> CaCO3 + H2OCa (OH) 2 + CO 2- > CaCO 3 + H 2 O

한편, 상기 송풍수단(100)의 연결부(110)는 그 구성을 달리할 수 있는데 예 를 들면 상기 송풍수단(100)의 메인관(120)과 직교 연결되는 헤더관(130)으로부터 다수개의 분기관(131)이 각각 연결 돌출되며 반응조(200)를 관통하여 연소가스를 상기 반응조(200) 내부로 유입되도록 할 수 있다.On the other hand, the connecting portion 110 of the blowing means 100 may have a different configuration, for example, a plurality of branch pipes from the header tube 130 orthogonally connected to the main pipe 120 of the blowing means 100. Each of the 131 is connected and protruded to penetrate the reaction tank 200 to allow combustion gas to flow into the reaction tank 200.

상기 분기관(131)은 그 직하방으로 전술한 침수관(132)의 형태를 취하지 않으면서 반응조(200)를 관통하되, 반응조(200) 내주면에 근접한 상태로 관통되도록 구성하게 된다.The branch pipe 131 penetrates through the reaction tank 200 without directly taking the form of the submerged pipe 132 described above, but is penetrated in a state close to the inner circumferential surface of the reaction tank 200.

따라서, 이러한 구성을 갖게 되면 송풍수단(100)으로부터 유입되는 연소가스는 반응조(200) 하단측으로 공급되어지되 액상의 약제 수표면층과 충돌되면서 반응이 발생되어진다.Therefore, if such a configuration has a combustion gas flowing from the blowing means 100 is supplied to the lower side of the reaction tank 200, the reaction is generated while colliding with the liquid drug surface surface layer.

한편, 상기 반응조(200)는 하단 일측에 상기 송풍수단(100)과 연결되는 연결부(110)가 전술한 바와 같이 연결 구비되고, 하단 타측으로 상기한 이산화탄소 제거용 액상 조성약제를 제공하기 위한 약제저장탱크(300)와 연결되어 반응조(200) 내부에 일정 수위 저장되도록 하고 있다.On the other hand, the reaction tank 200 is provided with a connection portion 110 connected to the blowing means 100 on the lower side as described above, the drug storage for providing the liquid composition for removing carbon dioxide to the other side of the lower side It is connected to the tank 300 is to be stored at a certain level in the reaction tank (200).

아울러, 상기 약제저장탱크(300)에 저장되는 약제를 펌프(P)에 의해 상방향으로 바이패스 유동시킨 후 다단 분사되도록 구성하였다.In addition, the drug stored in the drug storage tank 300 was configured to be multi-stage injection after the bypass flow upward by the pump (P).

즉, 상기 약제저장탱크(300)로부터 반응조(200)측으로 유입 공급되며 저장되는 액상의 약제는 펌프(P)의 작동에 따라 상방향으로 바이패스되면서 상기 반응조(200) 상단 내부측을 가로지르는 분사관(210)을 통해 반응조(200) 하방측으로 낙하되도록 하였다.In other words, the drug in the liquid supply is supplied to the reaction tank 200 side from the drug storage tank 300 and stored in the direction that is bypassed in the upward direction by the operation of the pump (P) to cross the inside of the reaction tank 200 top Through the pipe 210 to fall to the reaction tank 200 below.

여기서 상기 분사관(210)은 도면에서 보는 바와 같이 반응조(200)의 상하로 다단 형성할 수 있다.Here, the injection pipe 210 may be formed in multiple stages up and down of the reactor 200 as shown in the figure.

따라서, 상기 분사관(210)측으로 바이패스 유동되는 액상 약제는 반응조(200)의 상방측에서 하방측으로 분사되며 자연 낙하되는데, 반응조(200) 하방으로 저장되어 있는 약제와 반응한 후 상승되는 연소가스와 재반응을 일으키게 된다.Therefore, the liquid medicine that is bypassed to the injection pipe 210 side is injected from the upper side of the reaction vessel 200 to the lower side and is naturally dropped, the combustion gas is raised after reacting with the drug stored below the reaction vessel 200 Will cause a reaction with.

아울러 상기한 분사관(210)은 적정 개소에 등간격 이격되며 구성할 수 있게 되므로, 연소가스내 이산화탄소의 제거 효율을 증대시킬 수 있을 것이다.In addition, since the injection pipe 210 can be configured to be spaced at equal intervals in an appropriate place, it will be possible to increase the removal efficiency of carbon dioxide in the combustion gas.

또한, 상기 분사관(210) 상방향으로 필터부(220)가 구비되어, 상승되는 연소가스에 포함되어 있을 수 있는 불순물이나, 수분 등이 걸러지도록 하고, 상기 필터부(220) 상방향으로 간헐적으로 직수 공급되며 필터부(220)를 세척하기 위한 직수분사관(230)이 구비되도록 하였다.In addition, the filter unit 220 is provided in the upper direction of the injection pipe 210 to filter out impurities, moisture, and the like that may be included in the rising combustion gas, and intermittently upwards of the filter unit 220. Directly supplied to the water injection pipe 230 for washing the filter unit 220 was provided.

아울러 상기 직수분사관(230) 상방향으로는 연소가스가 배출되기 위한 배출관(240)이 형성되어, 전술한 과정을 거쳐 상승하는 연소가스를 외부로 배출되도록 하고 있다.In addition, the discharge pipe 240 for discharging the combustion gas is formed in the upward direction of the direct injection pipe 230, so as to discharge the combustion gas rising through the above-described process to the outside.

상기 배출관(240)은 연도로서, 대기중에 그대로 방출되도록 하거나 또는 별도의 공정을 거쳐 보다 완전히 연소가스내 포함되어 있는 유해성분이 제거되도록 한 후 대기상으로 배출될 수 있을 것이다.The discharge pipe 240 may be discharged to the atmosphere after being discharged to the atmosphere as it is, or to remove the harmful components contained in the combustion gas more completely through a separate process.
