Efficient spraying waste gas treatment method and equipment

Abstract

The invention discloses an efficient spraying waste gas treatment method. The method comprises the steps that 1, enabling spraying waste gas in a paint spraying room to enter a spraying tower; step 2,atomizing and spraying the spraying waste gas by a sprayer, removing solid paint particles in the spraying waste gas, enabling spraying water and the removed solid paint particles to fall into a circulating water tank, filtering the spraying water, and then circulating the spraying water for spraying, wherein 8-12% of vegetable oil and 1kg of sodium hydroxide are added into the circulating watertank; 3, enabling the spraying waste gas with the solid paint particles removed through spraying to enter an activated carbon adsorption tower again, and performing primary purification through the activated carbon adsorption tower; and 4, conveying the spraying waste gas subjected to primary purification into a photocatalyst adsorption tower, carrying out secondary purification to reach the emission standard, and discharging the spraying waste gas into the atmosphere. Vegetable oil and sodium hydroxide are added into the circulating water tank, so that the dust dyeing property can be improved, blockage and peculiar smell generated by liquid in the circulating water tank are avoided, and environmental pollution is prevented.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to an efficient spraying waste gas treatment method and equipment. Background technique [0002] Environmental problems have become a global problem, air pollution is one of the most prominent environmental problems, and industrial waste gas is an important source of air pollution, with the rapid development of industry, a large number of volatile organic compounds from various It is discharged into the atmosphere in various industrial activities, forming organic waste gas, which will bring serious air pollution, endanger human health, affect the normal growth of animals and plants, and also seriously restrict economic development and Improvement of people's living standards. [0003] Exhaust gas from spraying workshops generally includes two components: paint mist and volatile organic pollutants. Paint mist is the granular viscous organic matter that is not attached t...

AI Technical Summary

Problems solved by technology

[0004] The existing spraying exhaust gas treatment method only treats the spraying exhaust gas to meet the emission standard during the control treatment, but the spraying exhaust gas discharged also has a certain odor, and the existing spraying exhaust gas treatment equipment occupies a large area, and The treatment effect is average, therefore, it is necessary to provide an efficient spraying exhaust gas treatment method and equipment to control the pollution of the spraying exhaust gas to the environment
