Abstract: An exhaust gas processing device and method are disclosed for removing particulate and other materials from hot exhaust gas while muffling operational noises produced by the system emitting the exhaust gas. The device includes first, second and third portions through which the exhaust gas is successively passed, with the first portion receiving the exhaust gas and a liquid that is vaporized to coagulate particulate matter in the gas, the second portion including filters for removing particulate material coagulated in the first portion, and a with the third portion including a liquid containing reservoir and a filter for further cleansing the gas and also heating the liquid in the reservoir, which liquid is introduced into the first portion for vaporization thereat. The device and method are particularly useful in cleaning air exhausted from an internal combustion engine that may be used, for example, to power a motor vehicle.

Abstract: A multi-chambered air cleaning device is disclosed for removing particulate and other material from air passing through the device, as is a method for removing particulate and other matter from exhaust air. The device includes a front portion for collecting hot exhaust air to be cleaned and vaporizing the same to coagulate particulate matter in the air, and a back portion with a plurality of filters for removing the particulate material as well as other impurities such as gaseous odors. The device is particularly useful to clean air exhausted from a tail pipe connected with an internal combustion engine, and is also useful to clean gases emitted from pipes and/or stacks connected with combustion-type devices such as are commonly found in industrial plants.
