Description

Technical Field

[0001] The utility model relates to the technical field of paint spray booths, in particular to an environment-friendly paint spray booth. Background Technique

[0002] A paint spray booth is a device that provides a special environment for painting operations and can meet the requirements for temperature, humidity, illuminance, air cleanliness, etc. in painting operations.

[0003] Chinese Patent with the application publication number CN214864694U discloses an efficient and environment-friendly paint spray booth. In this patent, by jointly using two methods of suction and blowing, the paint mist waste gas in the paint spray booth is completely exhausted, ensuring that no part of the paint mist molecules remains in the air inside the paint spray booth body, and the extraction efficiency of the paint mist waste gas is high, which is worthy of popularization.

[0004] When using the above patent, we found that the filter layer in the device is not easy to clean and replace. After a long time, the filter layer will adsorb a large amount of dirt, thus affecting the gas filtration effect. Therefore, we propose an environment-friendly paint spray booth.
