Description

다단 습식 집진기{Multi stage wet scrubber}Multi stage wet scrubber

본 발명은 다단 습식 집진기에 관한 것으로, 보다 상세하게는 물 또는 액체와 접촉되는 면적을 극대화시켜 오염된 공기의 여과 효율을 현저하게 향상시킨 다단 습식 집진기에 관한 것이다.The present invention relates to a multi-stage wet dust collector, and more particularly, to a multi-stage wet dust collector in which the filtration efficiency of contaminated air is remarkably improved by maximizing the area in contact with water or liquid.

일반적으로 작업장에서는 분진형태의 오염물질이나 황화수소 같은 유해 가스가 많이 배출되고, 이를 정화하지않고 대기 중에 그대로 배출시킬 경우 환경 오염이 심각하게 발생한다는 문제점이 있다.In general, there is a problem in that a lot of pollutants in the form of dust or harmful gases such as hydrogen sulfide are discharged in the workplace, and if they are discharged to the atmosphere without purification, environmental pollution is seriously generated.

따라서, 공기에 포함된 오염물질과 유해 가스를 제거하기 위해 여러 방식의 집진기 또는 공기 정화 장치가 사용되는데, 그 중에서 습식 집진기는 오염물질이나 유해 가스를 물과 접촉시켜 여과하는 구조이다.Accordingly, various types of dust collectors or air purifiers are used to remove pollutants and harmful gases contained in the air. Among them, the wet dust collector has a structure that filters pollutants or harmful gases by contacting water.

이러한 습식 집진기는 일반적으로 단순히 물을 낙하시켜 낙하되는 물에 오염물질이 흡착 또는 제거되도록 하는 구조를 취하다 보니 여과효율이 높지 않은 문제점이 발생한다.In general, such a wet dust collector has a structure in which contaminants are adsorbed or removed from the falling water by simply dropping water, so that the filtration efficiency is not high.

본 발명은 습식 집진기 또는 공기 정화기로서, 유입되는 오염된 공기를 우선 물을 통해 여과시킨 다음 여과부재를 통해 2차적으로 다시 여과하고, 이어서 양측에서 분사되는 수산화나트륨 성분이 흡착된 나노단위의 물 입자를 통해 유해가스도 여과하며, 이러한 과정이 다단 또는 다층 구조에 의해 복수회에 걸쳐 수행됨으로써 종래 습식 집진기에 비해 유해 가스를 완벽히 제거하여 여과 효율을 현격하게 향상시킨 것이다.The present invention is a wet dust collector or air purifier, in which contaminated air is first filtered through water and then secondly filtered through a filter member, and then nano-scale water particles in which sodium hydroxide component sprayed from both sides is adsorbed. The harmful gas is also filtered through the filter, and this process is performed multiple times by a multi-stage or multi-layer structure, thereby completely removing the harmful gas compared to the conventional wet dust collector, thereby remarkably improving the filtration efficiency.

우선, 본 발명은 하우징(100)의 일측면에 오염된 공기가 유입되도록 공기 유입구(10)과 관통되고, 하우징(100)의 하부에 물이 저장되는 수조(11)가 구비된다.First, in the present invention, a water tank 11 is provided that penetrates through the air inlet 10 so that contaminated air is introduced into one side of the housing 100 and stores water in the lower portion of the housing 100.

상기 수조(11)의 물은 펌프를 사용하여 배수관을 통해 하우징(100)의 상부로 끌어올려져 낙하하게 된다.The water in the water tank 11 is pulled up to the upper part of the housing 100 through a drain pipe using a pump and dropped.

상기 공기 유입구(10)로 공기를 흡입하기 위해서는 흡입력이 발생되어야 하는 본 발명에서는 하우징(100)의 상측에 설치되는 모터(20)의 모터축에 연결된 흡입팬의 구동으로 하우징(100)의 내부로 공기를 유입시키는 흡입력을 발생시킨다. In the present invention, in which a suction force must be generated in order to suck air through the air inlet 10, the suction fan connected to the motor shaft of the motor 20 installed on the upper side of the housing 100 is driven to the inside of the housing 100. It generates a suction force that introduces air.

다시 말해, 본 발명의 흡입력 발생부(200)는 상기 하우징(100)의 상부에 일정 공간을 차지하며 하우징(100)의 상측에 설치되는 모터(20)의 모터축과 연결된 흡입팬이 내부에 설치되어 상기 공기 유입구(10)를 통해 상기 하우징(100) 내부로 공기가 유입되도록 흡입력을 발생시키는 것이다.In other words, the suction force generating unit 200 of the present invention occupies a certain space above the housing 100, and a suction fan connected to the motor shaft of the motor 20 installed on the upper side of the housing 100 is installed therein. As a result, a suction force is generated so that air is introduced into the housing 100 through the air inlet 10.

본 발명에서 유입된 공기는 여과가 이루어진 후 상기 흡입력발생부(200)의 상측에 구비되는 공기 배출구(300)로 배출된다.After the air introduced in the present invention is filtered, it is discharged to the air outlet 300 provided on the upper side of the suction force generating unit 200.

It is to spray to the upper side of the plate 400. Accordingly, the air filtered through the filtering member 500 undergoes a chemical reaction with the water particles sprayed from the filtrate spraying unit, thereby removing harmful gases. The salt generated after the chemical reaction is precipitated in the water tank 11.

In addition, the turbulence generator 700 is inside the housing 100 and faces the inside of the air inlet 10 so that the air introduced through the air inlet 10 is evenly distributed and flowed over the entire plane of the porous plate 400 Is installed.

상기 난류발생부(700)는 호 형상을 가지며 상하로 다수개 설치됨으로써 유입된 공기의 흐름을 난류로 만들어 주는 역할을 한다.The turbulence generator 700 has an arc shape and serves to make the flow of the introduced air into a turbulent flow by being installed in a plurality of vertically.

또한, 본 발명에서는 상기 수조(11)에 수위레벨센서, PH센서, 및 온도센서가 각각 설치되어, 수조(11)의 수위를 검출하여 물 공급을 제어할 수 있고, PH센서를 통해 물의 교체 시기를 제어할 수 있으며, 온도 센서를 통해 수조(11) 내의 물이 동결되지 않도록 제어할 수 있다.In addition, in the present invention, a water level sensor, a PH sensor, and a temperature sensor are respectively installed in the water tank 11, and the water supply can be controlled by detecting the water level in the water tank 11, and the replacement time of water through the PH sensor Can be controlled, and the water in the water tank 11 can be controlled so that it does not freeze through a temperature sensor.

이상에서 본 발명의 실시예를 설명하였으나, 본 발명은 그 기술적 사상의 범위를 벗어나지 않는 한도내에서 다양한 변형이 가능함은 당업자에게 있어서 자명하다. 따라서, 상기 내용은 하기 특허청구범위에 의해 정해지는 본 발명의 범위를 한정하는 것이 아니다.Although the embodiments of the present invention have been described above, it is apparent to those skilled in the art that the present invention can be variously modified without departing from the scope of the technical idea.
