Brief introduction of activated carbon waste gas adsorption tank:
The activated carbon waste gas purifier is a kind of dry waste gas treatment equipment. The utility model is composed of a box body and an adsorption unit filled in the box body. According to the number of adsorption units and air volume, different specifications can be combined. Different fillers can be selected by the activated carbon waste gas purifier to deal with different kinds of waste gas, mainly used for the purification of organic waste gas such as paint. For the exhaust gas with concentration lower than 1000mg / m3, the emission after purification shall meet the comprehensive emission standard of air pollutants (GB16297-1996). The equipment is activated carbon adsorption device, which needs to be used together with activated carbon regeneration system (nano photocatalytic oxidation device). The main advantages of the activated carbon adsorption device are high adsorption efficiency, low operation cost, convenient maintenance, and the ability to process a variety of mixed exhaust gas at the same time.
The activated carbon waste gas adsorption box is a kind of high-efficiency, economical and practical equipment for purification and treatment of organic waste gas, and an environmental protection equipment product for waste gas filtration and absorption of peculiar smell. The equipment is an adsorption equipment for purifying high concentration organic waste gas and spray paint waste gas. It uses the high strength adsorption of activated carbon and the function of fan to adsorb organic waste gas molecules, which has a good adsorption effect on organic solvent waste gas.
Introduction to painting waste gas:
Paint spraying mainly depends on its spraying mode and size of spraying surface (involving the size of paint consumption). The most important thing is to analyze the composition of paint (especially the proportion of diluent), most of which is volatilization in the process of baking or baking. Spray paint raw material - the paint is composed of nonvolatile and volatile, nonvolatile includes film-forming material and auxiliary film-forming material, and volatile refers to solvent and diluent (mainly two). The organic gas in the paint waste gas comes from the volatilization of solvent and diluent. The organic solvent will not adhere to the paint surface with the paint, and will be released to form organic waste gas in the process of painting and curing. The amount of two waste gases volatilized in the painting process accounts for about 30% of the diluent consumption, and another 70% volatilized in the drying process. The two-phase suspended substance formed by the atomization of paint and solvent in the painting and coating operation escapes into the surrounding air and pollutes the air. The collection and separation of paint mist in polluted air is the main method to improve the quality of paint spraying, improve the environment of paint spraying and meet the requirements of environmental protection.
Application scope of activated carbon adsorption filter:
The activated carbon adsorber is mainly used for deodorization and purification of odorous gas and flue gas in paint spraying room, printing plant, feed plant, plastic processing plant, oil refinery, rubber plant, chemical plant, pharmaceutical plant, sewage treatment plant, electronic original production, battery (battery) production, acid pickling operation, laboratory exhaust, metallurgy, coating, food, brewing and furniture, garbage transfer station, etc 。
Description of activated carbon adsorption device:
Activated carbon adsorption device is a kind of purification equipment with good treatment effect of organic waste gas and odor. Activated carbon adsorption is an effective measure to remove water odor, natural and synthetic dissolved organic matter, micro pollutants and so on. Most of the larger organic molecules, aromatic compounds, Haloalkynes, etc. can be firmly adsorbed on the surface or in the pores of activated carbon, and have obvious removal effect on humus, synthetic organics and low molecular weight organics. As a deep purification process, activated carbon adsorption can also be used for the purification of long-term production water and domestic water after commonly used in the final treatment of wastewater. When there are more dust and particles, the activated carbon adsorption device can be used together with water curtain machine, water spray tower and UV plasma at the same time, so as to achieve the emission standard of waste gas purification.
Use of activated carbon adsorption tank:
The activated carbon adsorption box uses the activated carbon adsorption box, including a box body. The top of one end of the box body is provided with an air inlet, the lower part of the other end of the box body is provided with an air outlet, the top of the box body is provided with a number of activated carbon inlet, and the bottom of the box body is correspondingly provided with a number of activated carbon discharge openings. The activated carbon discharge opening is of the extraction type structure, and the active carbon inlet and the corresponding activated carbon discharge openings An active carbon adsorption layer is formed between the material openings, and a primary adsorption filtration device is arranged between the active carbon adsorption layer and the air inlet, and a plurality of observation openings are arranged on the outer wall of the box body. The utility model belongs to the fully airtight type, which can be used indoors and outdoors, and has the advantages of high adsorption efficiency, strong capacity, compact equipment structure, small floor area, simple and convenient maintenance and management, low operation cost, and being able to handle a variety of mixed organic waste gases at the same time
