Knight, Gary P.; Seeley, Andrew J.; Price, Duncan M.; Abatement system. US patent 10,702,824 July 7 (2020)
Venturi Scrubbers are used to separate particulate from a large range of fluids. Many provide additional liquid and/or gas to drive the fluid and aid in the removal of particulate. The present invention provides a liquid ring pump through which the fluid to be treated is first passed and then exhausted, with additional work fluid to a Venturi scrubber such that the particulate can be separated from the exhaust fluid.
