작업장의 분진처리장치{Dust process device of a workshop}Dust process device of the workplace

본 발명은 작업장의 분진 처리장치에 관한 것으로, 더욱 상세하게는, 작업장에서 발생되는 분진을 처리수로 처리하되, 분진이 포함된 처리수에 응집제을 투입하여 분진을 고형화시키도록 함과 아울러 처리수를 순환시켜 재사용하도록 하는 작업장의 분진처리장치에 관한 것이다.The present invention relates to a dust treatment apparatus of a workplace, and more particularly, to treat the dust generated in the workplace with the treated water, to add a flocculant to the treated water containing dust to solidify the dust and at the same time treated water. It relates to a dust treatment apparatus of a workplace to be recycled and reused.

일반적으로 각종 작업장의 실내작업시에는 산업기기의 작동과 잔여 원재료 및 작업자의 움직임에 의한 미세한 분진 및 쓰레기 등이 발생되는 바, 이러한 분진 및 쓰레기는 작업환경을 저해하는 요소로서, 작업자의 인체에 악영향을 끼칠 뿐만 아니라, 산업기계의 작동효율을 저하시키는 요인으로 작용하는 것이다.In general, when working indoors of various workplaces, fine dust and garbage are generated due to the operation of industrial equipment, residual raw materials, and worker's movements. These dusts and wastes are harmful factors to the human body of workers. Not only does this affect the operating efficiency of industrial machinery.

상기 작업장 중에서 제품의 표면에 녹이 스는 것을 방지하거나 색채를 갖는 외관을 갖도록 도장작업을 하는 작업장은 분진 등이 발생되고, 이를 처리하기 위한 측배기 습식 도장 부스 설비가 있다.In the workshop, the workshop to prevent rust on the surface of the product or to have a color-colored appearance has a dust or the like, there is a side exhaust type wet painting booth facility for treating this.

도 1은 종래에 따른 습식 도장 부스 설비의 일예를 나타낸 도면이다.1 is a view showing an example of a conventional wet painting booth equipment.

도시된 바와 같이 습식 도장 부스 설비는, 도장액 분사노즐(1)을 통해 도장액이 분무되어 제품(2) 표면에의 도장 작업을 시행한 후 흩날리는 여분의 도장분 진(1a)들은 외부로 배출하는 과정에 집진 및 분리시켜 회수하므로써 대기의 오염을 방지토록 하고 있다.As shown in the figure, the wet painting booth facility is sprayed with the coating liquid through the coating liquid injection nozzle 1 to perform painting on the surface of the product 2. The dust is collected and separated during the discharge process to prevent air pollution.

그런데 도장분진(1a)을 외부로 집진배출함에 있어서, 장치의 상부측에 수류판수조(3)를 설치하고 벽면(4)에 수직으로 수류판(4a)을 설치한 후 수류판용 급수배관(4b)을 통해 수류판수조(3)로 물이 흘러 넘치도록 공급하게 되면, 넘쳐흐르는 물이 수류판(4a)을 타고 마치 커튼처럼 흘러내리게 되며, 하부에 일정 수위를 유지토록 하부수조(5)에 저장되는 저장수위수면(6)에 접하도록 형성되는 물 커튼막이 외부와 단절된 일종의 밀폐공간을 형성하게 된다.However, in the dust collection and discharge of the coating dust (1a) to the outside, after installing the water flow plate water tank (3) on the upper side of the device and the water flow plate (4a) perpendicular to the wall surface 4, the water supply pipe (4b) When water is supplied to the water flow plate 3 through the water supply, the overflowing water flows down like a curtain in the water flow plate 4a, and the lower water tank 5 maintains a certain level at the bottom. The water curtain film formed to be in contact with the storage water level surface 6 to be stored forms a kind of closed space disconnected from the outside.

이때 외부에서 배기팬(7)으로 도장실(8)내의 공기(분사된 도장액을 포함하고 있음.)를 흡입하여 대기중에 배기하게 될 때, 물 커튼막의 하단이 파기되면서 하부수조(5)내의 저장수와 함께 공기 흐름을 따라 배기구(9)로의 이동이 일어나 공기에 휩쓸려 외부로 배기되어지게 되는 것이다.At this time, when the air in the coating chamber 8 (including sprayed coating liquid) is sucked from the outside to be exhausted into the atmosphere, the lower end of the water curtain film is destroyed and the inside of the lower tank 5 The movement to the exhaust port 9 along the air flow along with the stored water is swept away by the air and exhausted to the outside.

그러나, 종래와 같은 습식 도장 부스 설비에 사용되는 처리수는 분진이 침전된 폐수로서, 분진이 분리되지 않은 상태에서 하천에 그대로 방류되어 수질 오염을 야기함은 물론 처리수를 재활용하지 못하는 문제점이 있다.However, the treated water used in the conventional wet paint booth facility is wastewater in which dust is precipitated, and is discharged as it is in the river without dust being separated, causing water pollution and of course not reusing the treated water. .

그리고, 상기 열분해로(60)에서 분출되는 분진 및 연기는 연통(61)을 통해 상기 처리라인(72)으로 유입되고, 상기 처리라인(72) 상의 순환펌프(72a)에 의해 물탱크(71)의 물이 처리라인(72) 상의 유동되면서 분진 및 연기를 물과 희석시켜 대기중으로 분출되는 연기 등을 최소화하게 된다.In addition, the dust and smoke emitted from the pyrolysis furnace 60 is introduced into the treatment line 72 through the communication 61, the water tank 71 by the circulation pump 72a on the treatment line 72. As the water of the flow on the treatment line 72 dilutes the dust and smoke with water to minimize the smoke and the like emitted to the atmosphere.

또한, 상기 처리라인(72) 상의 희석된 분진 등은 제2바이패스 라인(73)을 통해 연결 배관(31)로 유동되고, 다시 응집제 투입부(30)를 통과하면서 응집제에 의해 응집되어 고액분리부(40)로 유입되어 고액이 분리되며, 상기 고액분리부(40)에서 분리된 물은 바이패스 라인(50)에서 분기된 제3바이패스 라인(74)을 통해 다시 물탱크(71)로 유입되어 물은 재활용 하게 되는데, 이때 제2개폐밸브(81)와, 제3개폐밸브는 개방되고, 제1개폐밸브(80)는 폐쇄된다.In addition, the diluted dust or the like on the processing line 72 flows to the connecting pipe 31 through the second bypass line 73, and is aggregated by the coagulant while passing through the coagulant inlet unit 30 to separate solid-liquid. The solid liquid is introduced into the portion 40 and the liquid is separated, and the water separated from the solid liquid separator 40 is returned to the water tank 71 through the third bypass line 74 branched from the bypass line 50. Inflow of water is recycled. At this time, the second open / close valve 81 and the third open / close valve are opened, and the first open / close valve 80 is closed.

그리고, 제1개폐밸브(80)을 개방하고, 제3개폐밸브(82)를 폐쇄하게 되면 물은 집진탱크(10)으로 유입되어지게 된다.When the first opening / closing valve 80 is opened and the third opening / closing valve 82 is closed, water is introduced into the dust collecting tank 10.

또한, 상기 고액 분리부(40)에서 분리된 분진덩어리는 다시 열분해로(60)에서 열분해하여 응집제를 재생하도록하는 것이다.In addition, the dust mass separated from the solid-liquid separator 40 is to be pyrolyzed in the pyrolysis furnace 60 to regenerate the flocculant.
