Abstract:
1. A pollution control device for reducing harmful gaseous emissions found in combustion exhaust gases, said device comprising: a body having a first portion and a second portion releasably connected together to form a chamber therebetween; an exhaust gas inlet on said body, said inlet defining an exhaust gas flow through area; an exhaust gas outlet on said body; at least one web member extending across said chamber, said at least one web member being sized and shaped to block a flow of said exhaust gases through said chamber, said at least one web member having a plurality of openings therethrough and a plurality of flow through catalytic converter elements held in said openings, said plurality of flow through catalytic converter elements: a) permitting the flow of said exhaust gases there-through from said inlet to said outlet, b) defining an exhaust gas flow through area at least equal to said exhaust gas flow through area of said inlet; and c) having catalytic surfaces for treating said exhaust gasses; and d) a conical flow control baffle extending into said chamber from said inlet toward the at least one web member to distribute the flow of said exhaust gases evenly to said plurality of flow through catalytic converter elements, wherein said device experiences substantially no pressure drop across the chamber between said inlet and said outlet.
