An apparatus for handling exhaust gases, such as diesel exhaust, which cools the exhaust gases as the gases exit a diesel engine, and then filters such gases to remove particulate material. A housing has an inlet pipe with perforations and a filling of a liquid through which gas bubbles as it exits the perforations in the inlet pipe. The gas bubbling through the liquid cools the gases. In order to maintain the bubbles at a desired size, a perforated or porous layer of material is provided in the liquid so that gas moves through the perforated layer before it exits the liquid. Preferably the gas exiting the liquid is then passed through a filter which is maintained in a wet condition by mist carried by the gases that is formed as the gases burst through the surface of the liquid. The fibers of the filter are maintained wetted so that particles of material do not adhere to the fibers and can be flushed therefrom.

Apparatus for cooling exhaust gases, comprising: a housing having an inlet for allowing gas to enter an inlet chamber, and an outlet for allowing gas to exit an outlet chamber, wherein the gas flows from the inlet chamber to the outlet chamber, the inlet chamber having a filling of liquid therein to a desired level; a perforated member at least partially submerged in the liquid, the gas entering the inlet chamber at a level below the perforated member, the perforated member being positioned at a portion of an inlet chamber relative to the gas inlet such that gas passes only through the liquid and the perforated member prior to reaching the outlet chamber after entering the inlet chamber at the inlet; and wherein the inlet comprises a hollow gas carrying tube extending into the inlet chamber and submerged in the liquid, the hollow gas carrying tube having openings directly through a wall thereof at a location such that the gas entering the inlet flows directly into the liquid, said hollow gas carrying tube having perforations facing in a direction generally opposite from the perforated member such that gas has to initially move in a direction away from the perforated member and then toward and through the perforated member to reach the outlet chamber, said perforated member having openings such that bubbles of the gas are reduced in size and the bubbles pass through the perforated member; and a filter member in said outlet chamber above the level of liquid in the inlet chamber for filtering gas as it passes to the outlet, the outlet chamber having an generally a closed bottom wall an inlet positioned such that gas moving to the outlet has to move above the filter and turn to enter the outlet chamber before passing through the filter.
