Description

The present invention relates to a paint mist collection device installed in a paint booth.

For example, as disclosed in Document 1, a wet-type paint mist collection device that guides exhaust gas sucked from a paint booth together with water into a venturi, and captures paint mist contained in the exhaust air with fine particles of water atomized by the venturi. has been widely used.
In contrast to wet-type paint mist collectors, dry-type paint mist collectors that trap paint mist by colliding exhaust air against a plate member have recently come into use. Dry-type paint mist collectors have the advantage of being energy-saving compared to conventional wet-type paint mist collectors in that they do not require power to drive a circulating water pump.
Patent Document 2 discloses a dry paint mist collection device formed by complicatedly bending a plate member in which a large number of openings are formed.
