Abstract:
apparatus for removing diesel particulate and gases from a diesel internal combustion exhaust and apparatus comprising of:a soot separator attached to a catalytic converter of a diesel exhaust system for receiving and removing particulate from the exhaust, whereas the soot separator removes particulate (soot) by a specially injected chemical (RP Super Filter Coat 421) into a chamber to which the particulate will enter and be contained in a reservoir;a heat exchanger attached to the soot separator (attached to a diesel exhaust system) for receiving and cooling exhaust passing there through and condensing at least a portion of the exhaust into a liquid condensate;a first chemical reactor fluidly communicating with said heat exchanger for receiving and removing the condensate and draining into a holding tank associated therewith, the first chemical reactor exposing the condensate to a neutralizing agent contained therein to neutralize acids in the condensate;at least one second chemical reactor fluidly communicating with said first chemical reactor for receiving non-condensed gases from said first chemical reactor and reacting carbon monoxide, carbon dioxide, and nitrogen oxide contained in a non-condensed gases with a substance contained in said second chemical reactor which absorbs carbon monoxide, carbon dioxide, and nitrogen acids and removes at least some of said particulate matter from the non-condensed gases and discharges a balance of said exhaust through an outlet, wherein said second chemical reactor drains into a first chamber fluidly communicating therewith;a first drain conduit is connected to said heat exchanger and said first chamber to provide fluid communication there between for a portion of said liquid condensate formed in said heat exchanger; andsaid first chamber fluidly communicate with said holding tank through a second drain conduit extending there between.
