Venturi reactor and scrubber with suckback prevention

摘要

A venturi eduction and scrubbing system comprising a first container and a second container in fluid communication, each having a liquid treatment reagent therein. The liquid treatment reagent establishes liquid levels in the first and second containers. A waste inlet which contains waste gas or liquid to be processed is connected to at least one venturi eductor. The venturi eductors are also connected to the first container and are disposed above the liquid level of the first and second container. A pump is connected to the second container and each venturi eductor. The pump enables liquid treatment reagent to be pumped from the second container into the venturi eductors such that the waste gas or liquid is drawn from the waste inlet into the venturi eductors where it combines with the liquid treatment reagent and is thereby neutralized. The arrangement of [contains] containers and venturies provides a failsafe mechanism for preventing suckback into the waste container (which is usually the first container).
