Abstract: An exhaust gas cleaning system adapted to clean smoke or other waste gases through a liquid bath process. This system comprises a generally cubicle enclosure divided internally into three separate compartments. The first compartment includes means for inputting both a cleaning solution, preferably water, and a dirty exhaust gas for cleaning. Liquid level is maintained relatively constant by a float-actuated door system. A barrier disposed within the compartment prevents liquid turbulance. An adjacent intermediate compartment is in fluid flow communication with the inlet compartment via a submerged liquid passageway through which gases may be drawn by suction. Perforated plate means disposed within the intermediate compartment removes particulate matter from the liquid cleaning solution, and the resulting sediment is deposited in an adjacent auger equipped sediment pit for removal from the system.
