Spray paint mist treatment device

Spray paint mist treatment device 1. Product overview
The spray painting process is widely used in machinery, electrical equipment, home appliances, automobiles, ships, furniture and other industries. Spray paint raw materials (coatings) are composed of non-volatile components and volatile components. The non-volatile components include film-forming substances and auxiliary film-forming substances, and the volatile components refer to solvents and diluents. The organic gas in the spray paint exhaust gas comes from the volatilization of solvents and thinners. The organic solvents will not adhere to the surface of the spray paint with the paint. During the spray painting and curing process, they will all be released to form organic waste gas. The paint mist particles in the spray painting exhaust gas are small, have high viscosity, and are easy to adhere to the surface of materials. The paint mist must be removed before purifying the organic waste gas. The traditional paint mist removal method generally uses a water-washed spray booth. This method has low purification efficiency and cannot meet the treatment requirements. Through experiments and engineering practice, it has been shown that atomized washing and ultra-fine filtration processes are effective in removing paint mist, and the efficiency is as high as above. If the remaining small amount of exhaust gas is combined with the activated carbon adsorption process, it can fully meet the national emission standards.
2. System Working Principle
Painting exhaust gas is generated from the painting workbench for painting workpieces. Most of the paint sprayed by high-pressure air remains on the workpiece, and the rest is carried out with the exhaust gas to form paint mist and dust. . The dust content is not high and the particle size is small, most of which are below. The paint mist outside the tower enters the filler-free spray paint mist purification tower under the suction of the fan. The gas is distributed through the gas distributor in the tower and then flows Walking above the tower, during the walking process, you encounter the purification liquid of multi-stage spray washing. The paint mist and the liquid are in complete saturated contact. The granular dust mist is taken away by the water and enters the liquid storage tank, and is pumped away by the water pump. The remaining After the clean exhaust gas is filtered by the mesh filter, it then enters the next set of multi-stage spray washing processes. After another multi-stage spray washing process, the remaining air after filtering by the mesh ultra-fine filter is discharged.
The gas discharged from the paint mist purification tower enters the gas-liquid separator for gas-water separation. The separated gas then enters the activated carbon adsorption purification tower. The activated carbon purification tower uses the high-efficiency adsorption material-activated carbon to adsorb organic gases. Strong advantages to purify the air. The activated carbon purification tower is composed of an air inlet, an activated carbon filter section and an air outlet section. The organic waste gas enters the tower body from the air inlet, and the purified exhaust gas that meets the standard is discharged to the atmosphere under the suction of the ventilator.
