The invention provides a paint spraying waste gas treatment device and a treatment process thereof and relates to the technical field of paint spraying waste gas treatment projects. Paint spraying waste gas is pretreated by an efficient spraying tower to remove oil paint particle adhesive aggregation substance and then enters a demisting filter; moisture and fine and small oil paint particle adhesive aggregation substance in the waste gas subjected to spraying pretreatment is removed in the demisting filter; the waste gas subjected to treatment of the demisting filter enters an efficient activated carbon absorber, and residual pollutants in the waste gas is adsorbed and removed by activated carbon; after saturation of the activated carbon adsorption, catalytic combustion is conducted on the waste gas pollutants adsorbed by the activated carbon by utilizing a catalytic combustion device to restore the adsorption capacity of the activated carbon; standard-reaching discharge of the waste gas subjected to spraying, demisting filtration and activated carbon adsorption treatment. By adopting the paint spraying waste gas treatment device and the treatment process thereof and utilizing the demisting filter, the activated carbon load is greatly decreased, the catalytic combustion device can make activated carbon desorbed and regenerated, the service life of the activated carbon is prolonged, the frequency replacement of activated carbon is avoided, and the operation cost of waste gas treatment is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of paint spray waste gas treatment engineering, in particular to paint spray waste gas treatment equipment and a treatment process thereof. Background technique [0002] At present, there are five main methods of spray paint exhaust gas treatment: activated carbon adsorption method for spray paint exhaust gas treatment, catalytic combustion method for spray paint exhaust gas treatment, washing absorption method for spray paint exhaust gas treatment, direct combustion spray paint exhaust gas treatment, and ion spray paint exhaust gas treatment method. [0003] Among them, the activated carbon adsorption method has high operating costs and high maintenance costs; the organic solvent contained in the waste gas can be recovered and utilized. When activated carbon is regenerated, the equipment occupies a large area, consumes a lot of energy, and is expensive; when the temperature of the exhaust gas in the drying ...
