DRY VENTURI TRAPPING DEVICE FOR PAINT MIST AND APPLICATION THEREOF

WIPO Patent Application WO/2017/012224

A1

Disclosed is a dry venturi trapping device for paint mist (100), comprising a device housing. Multiple rows of paint mist filtration and interception units are arranged in a staggered manner in the device housing. A gap is left between adjacent paint mist filtration and interception units in the same row, and the gap and the faces of the paint mist filtration and interception units at two sides of the gap form an air flow channel having a venturi structure. The trapping device for paint mist filters and intercepts paint particles by means of filtration in an early stage and filters and intercepts paint particles by means of combined filtration and impact force in a late stage. Further disclosed is a dry paint spraying system with the above-mentioned dry venturi trapping device for paint mist (100). The trapping device for paint mist (100) is arranged at an air-discharging port of the paint spraying system to separate paint mist in the air.
