Description

A paint waste gas treatment device

technical field

The utility model relates to the technical field of waste gas treatment, in particular to a paint waste gas treatment device.

Background technique

In the process of producing paint, a large amount of exhaust gas and peculiar smell will be generated, including benzene, toluene and xylene, which will have a certain impact on the air quality in the workshop and its surroundings, and may cause harm to the human body. Therefore, it is necessary to treat the paint exhaust gas after reaching the standard. can be discharged.

At present, chemical plants mainly use water curtain paint mist treatment and glass fiber cotton filtration to treat paint exhaust gas. After the air containing paint mist collides with the water curtain, it passes through the water curtain and enters the air-water channel, where it has a strong interaction with the water in the channel. After entering the air collection box, the flow rate suddenly decreases, and the air and water are separated. After the air passes through the water baffle, it is drawn into the activated carbon adsorption device by the fan; the separated water flows into the overflow tank after the air collection, and the water flows from the The overflow tank overflows to the flashing plate to form a water curtain, and flows back to the water tank. In the process, the paint mist is formed into slag, thereby adsorbing and removing paint particles.

According to investigations, the removal efficiency of the water curtain paint mist treatment system for paint particles can only reach about 70%. The spray paint exhaust gas treated by the water curtain paint mist treatment system still contains a large amount of particles and has peculiar smell, which will still cause certain harm to the human body. harm.
