  • Wet scrubber and paint spray booth including the wet scrubber
    Patent number: 6093250
    Abstract: A wet scrubber including an acceleration cone for accelerating an airflow containing paint particles and having a curved inner wall on which water used for capturing paint particles flows downwardly, a mixing chamber for mixing the airflow and water and provided with an impingement pool on which the airflow impacts, a vortex chamber for creating a swirling flow of air and water that further aids the capture of paint particles, and a discharge volute communicating with the vortex chamber and provided with an enlarged discharge port for discharging the air and water. The wet scrubber is used in a paint spray booth, and provides the advantages of reduction in both energy consumption and noise and improvement in the efficiency of the capturing of paint particles.
    Type: Grant
