| 摘要 |
The present invention provides improved systems and methods for scrubbing gas with a venturi scrubber. A dual spray venturi scrubber, in which a scrubbing liquid is injected upstream and counter to the flow through the venturi, provides for improved scrubbing performance, including efficient and economical scrubbing of fine particles. Specifically, the present invention reduces the scrubbing liquid pumping requirements, improves the scrubber performance, and provides better control of the pressure drop across the venturi scrubber. The control of pressure drop across the venturi can be obtained with no internal mechanisms or upstream spray.
