Waste gas treatment device and process of water based paint

Abstract

The invention belongs to the technical field of waste treatment equipment and particularly relates to a waste gas treatment device of water based paint. The waste gas treatment device comprises a water-whirling spray treatment cabinet, a filtration purification room, a photolysis catalytic purification room, an activated carbon purification room and a blowdown stack that are connected with one another in sequence through pipeline, wherein a draught fan for driving waste gas to flow is arranged between the water-whirling spray treatment cabinet and the filtration purification room; a water curtain and a spraying device are arranged in the water-whirling spray treatment cabinet; the waste gas treated by the water-whirling spray treatment cabinet is filtered secondarily by the filtration purification room to further adsorb paint mist particles in the waste gas and remove moisture in the waste gas; the waste gas with the moisture removed enters the photolysis catalytic purification room, organic matters not easily soluble in water in the waste gas are removed by photolysis, residual organic matters and odor gas matters in the waste gas are adsorbed by the activated carbon purificationroom, and the finally qualified waste gas after treatment is emitted from the blowdown stack. The invention aims at providing the waste gas treatment device of the water based paint, which is good incleaning effect and convenient to maintain and clean.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment equipment, in particular to a water-based paint waste gas treatment device. Background technique [0002] Spraying is a common method of using paint. When using it, the paint is dispersed into uniform and fine droplets by means of air pressure through a spray gun, and then applied to the surface of the object to be coated. The construction period of spraying is relatively short. A large area of ​​material can be loaded in a short time, which is convenient for mass production, and the surface of the product produced by the spraying process is smooth and delicate, so it is widely used in industrial production, but the paint is atomized during the spraying process, and the atomized paint Most of them adhere to the surface of the product, but some of the paint escapes in the air. Some of these paints will adhere to the machine, affecting the normal use of the machine, and some will be inha...

[0002] Spraying is a common method of using paint. When using it, the paint is dispersed into uniform and fine droplets by means of air pressure through a spray gun, and then applied to the surface of the object to be coated. The construction period of spraying is relatively short. A large area of ​​material can be loaded in a short time, which is convenient for mass production, and the surface of the product produced by the spraying process is smooth and delicate, so it is widely used in industrial production, but the paint is atomized during the spraying process, and the atomized paint Most of them adhere to the surface of the product, but some of the paint escapes in the air. Some of these paints will adhere to the machine, affecting the normal use of the machine, and some will be inhaled by the workers, affecting the health of the workers. So now Most factories are equipped with waste gas treatment devices, through which the gas containing paint waste gas is adsorbed and treated. Common waste gas treatment devices include swirl towers. Swirl towers have large operating loads and operating flexibility, and high mass transfer efficiency. Strong anti-blocking performance and other characteristics, but the common swirl towers on the market still have the following shortcomings: most of the swirl towers are high in height, which is inconvenient to install and use; and the swirl towers can only deal with water-soluble impurities in the exhaust gas, but Can not paint the malodorous gas substances in the exhaust gas, which will affect environmental sanitation
