A new design of wet scrubber for removal of fine particles from exhaust gas

Bag-house dust collectors are commonly used in the industry for removing solid particles from dust laden gas. Bag house filter media need to be periodically cleaned in order to remove accumulated particles from the filter surface. Pulse jet cleaning is the most common cleaning method but produces noise increment of about 30-40 dB, which is its major disadvantage. The present study reports on a new type of combined wet scrubber-Venturi scrubber in the shape of a cyclone. The proposed design eliminates the noise associated with the pulse jet filter-cleaning process and filter bag replacement costs. The experimental results were demonstrated with high efficiency in the design.
