Abstract

PURPOSE: Provided is a wet-type dust collector for purifying flue gas, which can effectively capture particulate air pollutant entrained in flue gas by finely bottom-bubbling the flue gas. CONSTITUTION: The wet-type dust collector comprises a device which is installed at the bottom of filtration tank and produces air bubbles and eject it into water; a porous plate(7) which is installed at the upper part of the filtration tank and produces noise when filtrated gas leaks out from water surface(6). The air bubble producing device(5) has many perforations and several gaps for water circulation.

Description

오염된 기체의 습식 집진장치{omitted}Wet scrubber of contaminated gas

지금까지는 오염된 기체의 집진장치가 여러종류 있는 중에 효과적인 장치로 널리 쓰이고 있는 장치가 습식 장치이다. 기체에 물을 분사해서 기체에 섞인 분진이 습기를 머금어 가라앉게 하는 방법이다.Until now, there are many kinds of dust collectors for polluted gas, and the device which is widely used as an effective device is a wet device. This is a method of spraying water on a gas to allow the dust mixed in the gas to sink in moisture.

그러나, 그것은 기체의 분자들 개체 전체에는 습기가 접하지 못해서 그냥 빠져나가는 기체 분자들로 인해 분진이 완전하게 제거된다고는 볼 수 없다. 또, 개선된 방법으로 물속에 연통을 투입하고 분출시키는 방법도 생각해 볼 수 있으나 그것또한, 기체 덩어리로 크게 뭉쳐서 물밖에 나오는 관계로 만족한 결과는 얻을 수 없다고 본다.However, it does not mean that dust is completely removed by gas molecules that simply escape due to the lack of moisture in the entire gas molecules. In addition, it is possible to think of a method of injecting and ejecting communication into the water as an improved method, but it is also possible to obtain a satisfactory result because it is largely aggregated into a gaseous mass and comes out of the water.

따라서 본 발명은, 오염된 기체가 물속 밑에서 미세한 구멍들이 다공된 기포장치에서 기포를 발생시켜 물에 분진을 최대한 빼앗기게 하는 것으로, 기체가 최소 크기의 알갱이들로 나뉘어져 상승하면서 물과 직접 접하는 표면적이 넓고 또 접하는 시간이 길어져서 분진은 절대로 공기와 같이 빠져 나가지 못하게 하는데 목적한 것이다.Therefore, in the present invention, the contaminated gas generates bubbles in the bubble device in which the fine holes are porous under the water, so as to deprive the dust of the water as much as possible. The wider and longer contact time is intended to prevent dust from escaping with air.

도 1은 본 발명의 습식 집진장치의 2개조가 직렬로 연설되어 작용하는 것을 설명하는 정 단면도1 is a cross-sectional view illustrating that two sets of the wet dust collector of the present invention are acted in series.

도 2는 오염된 기체를 기포로 발생시켜 물속에 분사하기 위한 미세 다공된 기포 발생장치의 사시도Figure 2 is a perspective view of a microporous bubble generator for generating contaminated gas into the bubble to spray into the water

도면과 같이 철제의 원통으로 된 여과조 (A)와 여과조 (B)는 물이 채워져 있다.As shown in the drawing, the steel filtration tank A and the filtration tank B are filled with water.

오염된 기체가 일단 전기 집진기로 분진의 큰 알갱이가 걸러지고 도착되어 연통(1)을 통해 송풍장치(2)로 강하게 송풍되어 →표 방향으로 진행하는데, 거기에 연설된 연통(3)을 통해 기체가 밀면 위로는 열리고, 미는것을 멈추면 수압으로 인해 닫혀서 물이 새지 않는 수문(4)를 거쳐서 미세하게 다공된 기포 발생장치(5)에서 잘게 분산되어 기포를 발생시키면서 분출, 물속에 퍼져서 상승하면서 분진은 물에 잡아 먹히게 되고, 수면(6)의 위로 빠져나옴에 있어서 물끓는 소리가 발생하므로 다공판(7)를 통과 하면서 소음이 되는것이다.Once the polluted gas is filtered and large particles of dust arrive at the electrostatic precipitator, it is blown strongly to the blower (2) through the communication (1) → proceeds in the direction of the table, the gas through the communication (3) addressed there When it is pushed, it opens up, and when it stops pushing, it is closed due to water pressure, and it is finely dispersed in the microporous bubble generator (5) through the water-tight gate (4). Is eaten by the water, so that the sound of boiling in the exit of the water surface (6) is passing through the perforated plate (7) is a noise.

또다시 송풍장치(8)로 여과조(B)의 밑을 향해 강제 송풍되고 연통(9)를 통해 수문(10)을 통과하는 식의 역시 같은 원리가 반복 되지만, 보다 더 미세하게 작은 구멍들이 다공된 기포 발생장치(11)에서 거의 분자로 나뉘어 질만큼 잘게 분사되어 물에 섞여서 또 한번 요동을 치는데 더욱 맑게 여과된 기체만 빠져나가 다공판(13)을 통과 소음이 되어 정숙해지고 연통(14)에서 밖으로 방출된다.Again, the same principle is repeated, with the blower 8 being forced to the bottom of the filtration tank B and passing through the water gate 10 through the communication 9, but with smaller pores In the bubble generator (11), it is sprayed finely to be divided into molecules, mixed with water, and shaken once more, and only the clearer filtered gas passes through the porous plate (13) to be quiet and quiet, and out of the communication (14). Is released.

다시 말해서 물속에서 기체가 미세한 알겡이로 나뉘어 물이 그것들을 감싸고 물의 표면장력으로 인해 분진을 빨아들이는데, 상승하면서 마찰하므로, 반복적으로 계속 빨아들이는 것이다. 결과적으로 완벽한 여과를 하는 것이다.In other words, the gas breaks down into fine grains in the water, which envelops them and sucks up the dust due to the surface tension of the water. The result is perfect filtration.

한편, 여과조(A)와 (B)의 하단부에 설치한 기포 발생기는 도 2와 같은 형상으로 되었는데, 그 사이 공간부(15)들과 둘레의 여유 틈새를 통해 더러워진 물은 슬러지를 포함하여 배수구(②)를 통해 배출되어 정화조로 보내져 여과하고 충분한 산소공급의 공정을 거쳐 입수구(①)로 양수하는 식의 순환식으로 물을 재활용하여 외부에 유출시키지 않으므로써 환경오염을 최소화 하는 것이다.Meanwhile, the bubble generators installed at the lower ends of the filtration tanks (A) and (B) have a shape as shown in FIG. 2, wherein the water soiled through the clearances between the spaces 15 and the circumference therebetween includes sludge and drains ( It is discharged through ②) to be sent to the septic tank, filtered and pumped to the inlet (①) through the process of supplying enough oxygen to recycle water to minimize the environmental pollution by not leaking to the outside.

추가 설명으로 송풍되는 기체에 석여있는 수증기가 액화되어 고인물을 빼주기 위해 밸브(③)을 설치한 것이다.As a further explanation, a valve (③) was installed to drain the debris by liquefying water vapor in the gas being blown.

이상과 같은 장치는 발생되는 기체의 오염 정도에 따라서 여과조의 높이를 달리하고, 나아가서 여과조의 수를 달리해서 거기에 맞는 규모의 시설을 하게 될 것이다.Such a device will vary the height of the filtration tank according to the degree of pollution of the gas generated, and further, the number of filtration tanks will be different, so that the facilities of the scale will be suitable.

본 발명은 분진과 악취를 완벽하게 제거해서 맑은 공기로 환원시키는 장치인데도 비교적 간단하게 설치 되면서 저렴한 비용으로 운영이 가능하므로 환경 공해 추방에 큰 역할을 할 것이다.The present invention is a device that completely removes the dust and odor to reduce to clean air, yet relatively simple installation can be operated at a low cost will play a big role in the removal of environmental pollution.
