Adsorption system dedicated to the removal of industrial volatile organic pollutants in spraying workshops

Abstract

The invention relates to an adsorption system specially used for removing industrial volatile organic pollutants in a painting workshop. The adsorption system comprises a spraying filtering device, an adsorption bed and an adsorption draught fan. The spraying filtering device comprises a tower; an air inlet is formed in the lower portion of one side of the tower; an air outlet is formed in the tower and located at the opposite side of the air inlet; a first filter layer, a second filter layer and a demist layer are arranged in the tower from bottom to top; bottom sprayers are evenly distributed below the first filter layer; middle sprayers are evenly distributed between the first filter layer and the second filter layer, and upper sprayers are evenly distributed between the second filter layer and the demist layer; a filter is fixedly installed on one side of the air outlet of the tower, the filter is provided with a filter air outlet which is connected with an adsorption air inlet of the adsorption bed through a pipeline, and an adsorption air outlet of the adsorption bed is connected with the adsorption draught fan through a pipeline. By means of the adsorption system, oil paint mist can be separated from the industrial volatile organic pollutants effectively, and the efficiency for processing the industrial volatile organic pollutants is improved.

Description

technical field [0001] The invention belongs to the field of adsorption systems, in particular to an adsorption system specially used for removing industrial volatile organic pollutants in spraying workshops. Background technique [0002] As the country pays more and more attention to environmental protection, air pollution control has become more and more popular. Industrial volatile organic pollutants are the most harmful pollutants in PM2.5. The existing treatment technology mainly adopts catalytic combustion method , the industrial volatile organic pollutants are adsorbed and concentrated by the adsorption bed, and then desorbed into the catalytic bed for combustion. The catalytic combustion method is very effective for industrial volatile organic pollutants without paint mist, but in some paint spraying The volatile organic pollutants in the workshop industry are often mixed with paint mist. When the adsorption bed is adsorbed, the paint mist will adhere to the adsorpti...

[0002] As the country pays more and more attention to environmental protection, air pollution control has become more and more popular. Industrial volatile organic pollutants are the most harmful pollutants in PM2.5. The existing treatment technology mainly adopts catalytic combustion method , the industrial volatile organic pollutants are adsorbed and concentrated by the adsorption bed, and then desorbed into the catalytic bed for combustion. The catalytic combustion method is very effective for industrial volatile organic pollutants without paint mist, but in some paint spraying The volatile organic pollutants in the workshop industry are often mixed with paint mist. When the adsorption bed is adsorbed, the paint mist will adhere to the adsorption material in the adsorption bed, causing the adsorption bed to fail to work normally, reducing the purification efficiency and increasing the purification treatment cost. , affecting normal production
