Description

스크러버 탈취장치 {Scrubber deodorizer}Scrubber deodorizer {Scrubber deodorizer}

본 발명은 스크러버 탈취장치에 관한 것으로, 보다 구체적으로는 악취 가스와 탈취 약액의 접촉 면적 및 접촉 시간을 증가시켜서 탈취 효율을 향상시킬 수 있는 스크러버 탈취장치에 관한 것이다. The present invention relates to a scrubber deodorizing device, and more particularly, to a scrubber deodorizing device capable of improving deodorization efficiency by increasing the contact area and contact time between a malodorous gas and a deodorizing liquid.

스크러버(Scrubber)는 악취가스를 액체에 접촉시켜서 악취가스 중의 가용성 성분을 액체로 용해시키는 장치로서, 먼지는 물론 고농도의 휘발성 유기 화합물과 같은 악취원인물질을 제거할 수 있고 유지비용이 저렴하여, 산업체와 대기오염 방지시설 등에서 널리 사용되고 있다.A scrubber is a device that brings odor gas into contact with a liquid to dissolve soluble components in odor gas into a liquid. It can remove odor-causing substances such as dust and high-concentration volatile organic compounds. It is widely used in air pollution control facilities, etc.

도 1은 종래 기술에 따른 스크러버의 개략적인 구성도이다.1 is a schematic configuration diagram of a scrubber according to the prior art.

도 1을 참조하면, 종래 기술의 스크러버는, 스크러버 본체(1) 내부에 소정의 여과부(4, 4a)가 설치되고, 하부 가스유입구(3)로 유입된 악취가스는 여과부를 거치면서 여과됨과 동시에 순환배관(5)을 통해 상부 분사구로 분사된 물과 함께 아래로 흘러내려 하부 수조(2)에 담긴다. 수조에 담긴 물은 분사구로 재순환 공급되거나 타측의 배수구(6)를 통해 배출하여 폐수로 처리하게 된다.Referring to FIG. 1, in the prior art scrubber, predetermined filtering units 4 and 4a are installed inside the scrubber body 1, and the odorous gas introduced into the lower gas inlet 3 is filtered through the filtering unit. At the same time, it flows downward along with the water injected through the circulation pipe (5) through the upper injection port and is contained in the lower water tank (2). The water contained in the water tank is recycled and supplied to the injection port or discharged through the drain port 6 on the other side to be treated as wastewater.

이러한 종래 기술의 스크러버는 유입된 악취가스가 스크러버 본체(1) 내부에서 한쪽으로 치우쳐서 유동하는 편류현상으로 인해 악취 가스와 약액과의 접촉면적 및 접촉시간이 감소하여 효율이 감소되고, 효율 감소에 따라 설비의 규모를 증가시켜야 하므로, 시설 투자 비용 및 시설 유지 비용이 증가하는 문제가 있다.In the scrubber of the prior art, the contact area and contact time between the odor gas and the chemical liquid are reduced due to a drift phenomenon in which the odorous gas introduced is biased to one side inside the scrubber body (1), resulting in a decrease in efficiency. Since the size of the facility must be increased, there is a problem in that facility investment costs and facility maintenance costs increase.

회전모터(220)는 본체(100)의 외부에 형성되며, 체인(221) 및 체인기어(211)를 통해 다공판(210)과 연결되어, 다공판(210)을 시계방향 또는 반시계방향으로 회전시킨다. 물론, 설계에 따라 회전모터(220)는 본체(100) 내부에 설치될 수도 있다.The rotation motor 220 is formed on the outside of the main body 100 and is connected to the perforated plate 210 through a chain 221 and a chain gear 211 to rotate the perforated plate 210 clockwise or counterclockwise. rotate Of course, the rotary motor 220 may be installed inside the main body 100 according to design.

다공판 상부에는 폴링부(230)가 설치되고, 폴링부(230)에는 충진재인 폴링(Pallring)이 충진된다. A polling unit 230 is installed on the perforated plate, and the polling unit 230 is filled with Pallring, which is a filler.

폴링부(230) 상부에는 복수개의 분사노즐(240)이 설치되고, 분사노즐(240)은 각각은 탈취용 약액을 악취가스로 분사한다. 이때, 분사노즐(240) 각각은 별도로 연결 설치된 회전모터(미도시)에 의해 회전하면서 약액을 분사한다.A plurality of injection nozzles 240 are installed above the polling unit 230, and each of the injection nozzles 240 injects a deodorizing liquid into malodorous gas. At this time, each of the spray nozzles 240 sprays the chemical solution while rotating by a rotation motor (not shown) installed separately.

분사노즐(240) 상부에는 데미스터(250)가 설치된다. 다공판(210), 폴링부(230), 분사노즐(240)을 통과하여 악취원인 물질과 분진 등이 제거된 악취가스는 계속 상승하여 데미스터(250)를 통과하고, 데미스터(250)에서 가스에 포함된 액체 성분인 미스트(mist)가 제거된다.A demister 250 is installed above the spray nozzle 240 . The odorous gas from which odor-causing substances and dust are removed continues to rise and pass through the demister 250 through the perforated plate 210, the polling unit 230, and the injection nozzle 240. Mist, which is a liquid component contained in the gas, is removed.

이와 같은 제1 내지 제3 탈취부(110, 120, 130)에서 다공판(210)은 회전모터(220)에 의해 회전되도록 구성된다. 악취가스가 다공판(210)을 통과할 때, 회전되는 다공판(210)은 악취가스의 적어도 일부와 충돌하여 악취가스를 미세하게 만들면서 악취가스의 브라운 운동을 야기하게 된다. 악취가스가 미세하게 되고 불규칙한 브라운 운동을 하게 됨으로써, 이후의 과정에서 분사노즐(240)에 의해 분사되는 약액과의 접촉 면적 및 접촉 시간이 증가하게 된다. 또한, 분사노즐(240)도 회전하면서 회전하는 다공판과 유사하게 악취가스의 미세화 및 브라운 운동을 야기하게 된다. 따라서, 악취가스가 스크러버 본체(100) 내부에서 한쪽으로 치우쳐서 유동하는 편류 현상을 감소시켜서 전체적으로 탈취 효율을 향상시킬 수 있게 된다.In the first to third deodorizing units 110 , 120 , and 130 , the perforated plate 210 is configured to be rotated by the rotary motor 220 . When the odorous gas passes through the perforated plate 210, the rotating perforated plate 210 collides with at least a portion of the odorous gas to make the odorous gas fine and cause Brownian motion of the odorous gas. As the odorous gas becomes fine and performs irregular Brownian motion, the contact area and contact time with the liquid chemical sprayed by the injection nozzle 240 increase in the subsequent process. In addition, the injection nozzle 240 also rotates, causing refinement and Brownian motion of the odorous gas, similar to a rotating perforated plate. Therefore, it is possible to improve overall deodorization efficiency by reducing a drift phenomenon in which the odorous gas flows biasedly to one side inside the scrubber body 100.

After being removed by oxidative decomposition, it rides on the triangular pyramid-shaped second guide member 131 and falls to the second recovery surface 132 installed on the lower surface of the second guide member 131, and passes through the second recovery pipe R2. It is returned to the oxidizing agent tank (T3).
