Abstract
An improved gas scrubber system is disclosed in which air from a paint spray booth is mixed with a liquid to remove paint particles and other contaminants in the air. A wall is positioned immediately downstream of an outlet of the gas scrubber and a jet of intermixed water, entrained contaminants and air impinges off of that wall, to separate the majority of water and contaminants. The gas scrubber member has a unique structure such that the air and water are directed through a first portion generally aligned with an inlet and into a second portion which extends at a 90.degree. angle with respect to the first portion. A restriction is formed on the first portion to provide a noise barrier. The gas scrubber member is formed by planar walls to ensure that the water continues to adhere to them under surface tension, and in essentially laminar flow, while in the first portion. A top wall is spaced from a base wall to define the second portion. The top and base wall are configured such that water will continue to adhere to them until reaching a position adjacent the outlet nozzle, ensuring that the turbulent mixing of water and air occurs at the outlet nozzle. Thus, noise from the mixin…
