Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas collection and treatment device for a paint spraying room. Background Art

[0002] The jet process is widely used in many fields. During the painting process, waste gas containing volatile solvents, diluent molecules and paint particles will be generated, which will pollute the surrounding environment and be detrimental to the health of workers. Therefore, it is necessary to deploy corresponding waste gas treatment devices to treat the waste gas from painting. The paint particles and water-soluble substances contained in the waste gas from painting cannot be treated effectively by using only a filter. In addition, traditional waste gas treatment devices are bulky, time-consuming and labor-intensive to install, and are generally fixed in position after installation. When the location of the waste gas in the paint room changes, the distance between the waste gas treatment device and the location where the waste gas is generated changes. When the distance between the two increases, it will hinder the collection of waste gas, thereby affecting the waste gas treatment effect. Utility Model Content
