An improved gas scrubber is provided which is particularly suited for cleaning and cooling the exhaust gases from a diesel powered mine vehicle. The invention is embodied in apparatus including an enclosure which is partially filled with a liquid such as water. An inlet for the exhaust gases is located above the liquid level, as is also an outlet for the cleaned gases to escape. A tube connected to the inlet extends downwardly to below the water level, then changes direction and extends upwardly with constantly increasing cross section and with at least some portion of it in curvature to an open end interiorly of the enclosure and above the liquid level. One or more orifices in the submerged portion of the tube admit water droplets which are sucked into and turbulently mixed with the high velocity gases in proportion to the amount of combustion exhaust from the engine. The water droplets and particulate matter are separated from the gas stream by the combination of centrifugal force and their own gravity when the gas stream is slowed down. |
