Description

Technical Field

[0001] This utility model relates to the field of rail transit component production technology, specifically an environmentally friendly cleaning device for a rail transit painting production line. Background Technology

[0002] The painting process for rail transit vehicles typically involves large amounts of paint, solvents, and chemicals. These substances may release harmful gases and particulate matter during the spraying, drying, and curing processes. The introduction of environmentally friendly cleaning devices aims to reduce the impact of these harmful substances on the environment and worker health through effective capture and treatment technologies.

[0003] Traditional rail transit painting production lines have environmental cleaning devices that are located in open spaces during the painting process, resulting in low efficiency in treating pollutants and some of them still having an impact on the environment. Furthermore, replacing environmental filters is quite troublesome. Utility Model Content
