1、 Product overview of chemical scrubber:
The scrubber system uses the fan unit to suck the collected waste gas into the scrubber and flow through the filling layer section (gas / liquid contact reaction medium), so that the waste gas can fully contact with the liquid medicine (washing liquid) flowing on the surface of the filler, so as to adsorb the acidic or alkaline dirt contained in the waste gas. After washing, the waste liquid is collected in the water collecting tank and then discharged to the waste water system for treatment.
2、 Principle of chemical washing technology:
The scrubber uses the contact between gas and liquid to transfer the pollutants in the gas to the liquid, and then separates the clean gas from the polluted liquid to clean the air. The waste gas is treated by gas-liquid reverse absorption through the packed scrubber, that is, the liquid is sprayed down in mist (or small droplets) from the top of the tower. The waste gas reaches the purpose of gas-liquid contact from the tower body (reverse flow). This treatment method can cool waste gas, regulate gas and remove particles, and then discharge them into the atmosphere after treatment in the demisting section.
3、 Standard configuration of scrubber:
Window and maintenance manhole, air inlet flange, outlet flange, detergent inlet, overflow outlet, drain, filler, circulating water pump, circulating water filter screen, circulating water pipeline, sprinkler nozzle, etc.
4、 Product features:
1) The water washing waste gas treatment system has the advantages of low price and simple treatment method;
2) Vertical structure is most suitable for economic space installation;
3) Applicable to gaseous and liquid pollution sources;
4) Dealing with single pollution source;
5) Suitable for medium and low air volume.
The biggest feature of the vertical countercurrent scrubber is that the raw materials that can be comprehensively utilized in the waste gas can be recycled and treated by combination. The air volume of the single unit can be treated from 20m3 / min to 1500 m3 / min. the height of the washing and absorption area of the core part can be adjusted according to the different treated gases. The filler is made of PP, the shape is multi toothed, the porosity reaches 95%, and the specific surface area reaches 90m2 / m3; The filler of the dewatering layer is made of PP, which is circular arc in shape, with a void ratio of 95% and a specific surface area of 180 m2 / m3. The sprinkler head adopts pp120 degree rotation non blocking nozzle. There are no metal components in the system. Therefore, the whole system has high acid-base resistance; The resistance of the whole system is less than 50mmaq, which greatly saves energy consumption.
5、 Scope of application
1) Treatment of various harmful gases such as H2S, Sox, NOx, HCI, NH3, ci2 and other odor gases;
2) Deodorization device of sewage treatment plant;
3) Process exhaust treatment of semiconductor optoelectronics industry;
4) Waste gas treatment of leachate storage tank of landfill;
5) Waste gas treatment from incinerators and industrial furnaces.
Electroplating, pretreatment, chemical industry, iron and steel industry, semiconductor manufacturing industry, dye industry, etc. of printed circuit board industry and electronic component industry.
6、 Processing results:
It can effectively and economically treat acidic and alkaline waste gas, and the removal rate can be as high as more than 99%.
