An apparatus for treating waste gas is provided to reduce the content of hydrogen sulfide contained in the waste gas, thereby creating pleasant environment for factory workers and dwellers living nearby. A waste gas inlet(110) communicates with a precipitation tank(100). Waste gas outlets(120) discharge waste gas, which is inputted into the precipitation tank through the waste gas inlet. A liquid catalyst storage tank stores a liquid catalyst including iron catalysts contained in water. A catalyst transferring pump(300) compulsorily transfers the liquid catalyst to at least one of the waste gas inlet and the waste gas outlets. Jet nozzles(400) are installed within the waste gas inlet and the waste gas outlets to jet the liquid catalyst. Turbulences(500) are installed below the jet nozzles within the waste gas inlet and the waste gas outlets. The turbulences form the flowing of the waste gas in a vortex type. A sediment transferring pump(600) compulsorily transfers the sediment deposited in the precipitation tank. A filter(700) discharges the liquid catalyst from the sediment transferred by the sediment transferring pump. A liquid catalyst recovery pipe(800) is installed at a rear end of the filter. The liquid catalyst discharged by the filter is returned to the liquid catalyst storage tank through the liquid catalyst recovery pipe.

미설명 부호 320은 액상 촉매 저장탱크(200)의 내부로 공기를 공급하는 공기 공급 배관이다.Reference numeral 320 is an air supply pipe for supplying air into the liquid catalyst storage tank 200.

상기와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

먼저, 황화수소가 함유된 폐가스가 각종 공장의 산업장등에서 자체의 배출 압력을 지닌 상태로 폐가스 유입구(110)를 통해 유입된 후, 침전탱크(100)를 통과하여 폐가스 배출구(120)를 경유하여 대기로 방출되는 폐가스의 유동 경로를 가진다.First, the waste gas containing hydrogen sulfide is introduced through the waste gas inlet 110 in a state having its own discharge pressure in various industrial plants, and then passes through the settling tank 100 to the atmosphere via the waste gas outlet 120. It has a flow path of waste gas discharged to.

이때, 촉매 압송펌프(300)를 가동하게 되면, 액상 촉매 저장탱크(200)내에 수용된 액상 촉매는 배관()을 따라 유동하여 폐가스 유입구(110)와 폐가스 배출구(120)내에 설치된 분사 노즐(400)에서 분사된다.At this time, when the catalyst pump pump 300 is operated, the liquid catalyst contained in the liquid catalyst storage tank 200 flows along the pipe () and the injection nozzle 400 installed in the waste gas inlet 110 and the waste gas outlet 120. Sprayed from

즉, 폐가스 유입구(100)와 폐가스 배출구(120)의 상부에서 하방향으로 액상 촉매가 분사되는 것이다.That is, the liquid catalyst is injected downward from the waste gas inlet 100 and the waste gas outlet 120.

한편, 액상 촉매는 상부에서 하방향으로 분사되는 반면에 폐가스는 공장등의 자체 배출 압력에 의해 하부에서 상방향으로 유동하게 되는 것이다.On the other hand, the liquid catalyst is injected from the top to the bottom while the waste gas is to flow from the bottom to the top by the discharge pressure of the factory itself.

따라서, 폐가스중에 함유된 황화수소는 액상 촉매와의 화학 반응에 의해 황산화물로 변화되어 침전탱크(100)내로 낙하되면서 침전된다.Therefore, the hydrogen sulfide contained in the waste gas is converted into sulfur oxides by chemical reaction with the liquid phase catalyst and precipitates while falling into the precipitation tank 100.

그리고, 폐가스 유입구(100)와 폐가스 배출구(120)내에 각각 설치된 터뷸런스(500)를 구성하는 블레이드(540)는 유동되는 폐가스의 저항체로 작용하여 외통체(510)에 대해 내통체(520)를 회전시키게 된다.Then, the blade 540 constituting the turbulence 500 installed in the waste gas inlet 100 and the waste gas outlet 120 respectively acts as a resistor of the waste gas flowing to rotate the inner cylinder 520 with respect to the outer cylinder 510. Let's go.

따라서, 블레이드(540)는 회전축(530)과 함께 회전되기 때문에 터뷸런스(500)를 통과하는 폐가스는 유입전과 비교하여 볼 때 그 흐름이 난류 상태로 변화되어 분사 노즐(400)에서 분사되는 액상 촉매와 혼합이 더욱 잘 이루어진다.Therefore, since the blade 540 is rotated together with the rotation shaft 530, the waste gas passing through the turbulence 500 is changed into a turbulent state as compared with before the inflow, and thus the liquid catalyst injected from the injection nozzle 400. The mixing is better.

결국, 폐가스중에 함유된 황화수소와 액상 촉매의 화학 반응이 층류 상태의 흐름일때의 폐가스에서보다 더욱 잘 이루어지게 된다.As a result, the chemical reaction of the hydrogen sulfide and the liquid phase catalyst contained in the waste gas is made better than in the waste gas in the laminar flow.

결과적으로, 최종 폐가스 배출구(120)를 통해 배출되는 폐가스에 함유된 황화수소의 함유량을 5ppm~1ppm으로 낮출 수 있게 되는 것이다.As a result, the content of hydrogen sulfide contained in the waste gas discharged through the final waste gas outlet 120 can be lowered to 5 ppm to 1 ppm.

여기서, 상기 폐가스 배출구(120)는 지그 재그 형상으로 다수회 절곡되게 구성할 수 있는데, 이렇게 함으로써, 보다 효과적으로 액상 촉매와 황화수소간의 반응 회수 및 반응 시간을 증대시켜 최종 폐가스 배출구(120)를 통해 배출되는 폐가스에 함유된 황화수소의 함유량을 더욱 낮출 수 있는 것이다.Here, the waste gas outlet 120 may be configured to be bent a number of times in a zigzag shape, thereby increasing the number of reactions and reaction time between the liquid catalyst and hydrogen sulfide to be discharged through the final waste gas outlet 120 more effectively. The content of hydrogen sulfide contained in the waste gas can be further lowered.

한편, 본 발명은 폐가스의 주성분이 이산화탄소일 때 배출되는 황화수소(H2S)의 함유량을 현저하게 낮춤으로써 이산화탄소를 회수하여 아크 용접시 재활용할 수 있어, 별도로 이산화산탄소 가스를 구입하지 않아도 되며, 구입 비용을 절감 할 수 있는 잇점이 있다.On the other hand, the present invention can significantly reduce the content of hydrogen sulfide (H 2 S) discharged when the main component of the waste gas is carbon dioxide can recover carbon dioxide and recycle during arc welding, there is no need to purchase carbon dioxide gas separately, This has the advantage of reducing the cost of purchase.

그리고, 본 발명은, 촉매 압송펌프(300)에 의해 압송되어 배관(310)을 따라 유동되는 액상 촉매중의 일부를 다시 바이패스배관(320)을 통해 바이패스시켜 약상 촉매 저장탱크의 내부로 유입되도록 할 수 있다.In addition, the present invention, a portion of the liquid catalyst which is pumped by the catalyst pump pump 300 and flows along the pipe 310 is again bypassed through the bypass pipe 320 to flow into the weak catalyst storage tank. You can do that.

이상 살펴본 바와 같이, 본 발명에 의한 폐가스 처리장치에 따르면, ㅍ폐가스중에 함유된 황화수소(H2S)의 함유량을 5ppm~1ppm으로 낮출 수 있도록 있도록 함으로써, 공장 근무자에 대한 쾌적한 근무환경 조성, 인근 지역주민에 대한 악취피해 방지 및 민원발생 요인을 제거할 수 있도록 하며, 부가적으로 폐가스의 주성분이 이산화탄소일 때 배출되는 황화수소(H2S)의 함유량을 현저하게 낮춤으로써 이산화탄소를 회수하여 아크 용접시 재활용할 수 있게 된다.As described above, according to the waste gas treatment apparatus according to the present invention, by reducing the content of hydrogen sulfide (H 2 S) contained in the waste gas to 5ppm ~ 1ppm, creating a pleasant working environment for the factory workers, nearby areas It is possible to prevent odor damage to residents and remove the cause of complaints.In addition, it significantly reduces the content of hydrogen sulfide (H 2 S) emitted when the main component of waste gas is carbon dioxide to recover carbon dioxide and recycle it during arc welding. You can do it.
