In the waste gas treatment process of the paint spraying room, the selection of dust removal equipment depends on the nature of the paint mist. According to different processes, it can be divided into two types: powdered and water-based paint viscosity. For powdered paint mist, since it is dry and non-sticky, it can be treated with a bag dust collector, which can effectively capture and separate powdered particles. However, for paint mist with high viscosity of water-based paint, bag dust collector is not the best choice, because the sticky components in the paint mist are easy to adhere to the bag, resulting in a significant reduction in the dust removal effect and may affect the normal operation and maintenance of the equipment.

 

For the treatment of waste gas with water-based paint viscosity, the cyclone tower is a more suitable choice. Under the action of centrifugal force, the dust-containing gas in the cyclone spray tower moves horizontally and centripetally, the dust-containing gas stays longer, and the washing effect is better, which completely improves the technical defects of the spray tower under certain specific working conditions, such as incomplete dust removal and easy clogging of the water spray tower. The product adopts special technology to avoid the blockage of water pumps and nozzles, greatly improving production efficiency. The water in the pool can be recycled to avoid the trouble caused by secondary pollution and save water resources. Several "circular cyclone barrels" and high-efficiency demister plates are installed in the cyclone tower. Solid filler balls are placed in the cyclone barrel. The top demister plate is used to purify the water mist to achieve the purpose of dehydrating the mist. The dust-containing gas swirls up in the tower and contacts the liquid swirl entering from the top of the tower on each plate to complete the dust removal task; through the action of centrifugal force, large particles in the exhaust gas sink into the pool, and finally are manually fished out and cleaned up the casing, so that the gas is purified and meets the emission standards. At the same time, the water in the cyclone tower can continue to be recycled.

 

In practical applications, for example, in the automobile repair industry, by using water-based paint instead of traditional oil-based paint, combined with UV paint roller coating and paint-free board replacement process, the emission problem of VOCs is solved from the source, while improving product quality and achieving effective promotion. This shows that in specific industrial applications, choosing the right dust removal equipment and process is crucial to achieving environmental protection and improving production efficiency.

 

In summary, the selection of dust removal equipment for the paint spraying room should be based on the specific properties of the paint mist. Powdered paint mist is suitable for bag dust collectors, while water-based paint viscosity is recommended to be treated with cyclone towers. Through reasonable equipment configuration and process selection, the efficiency and effect of exhaust gas treatment can be effectively improved.
