Patent CA-2220210-A1 (CA)
Title: Diesel exhaust conditioning system
Inventor: ROHRBAUGH DAVID
IPC: F01N3/30
Filed: 1997-11-04
Abstract: A diesel exhaust conditioning system removes harmful gaseous and particulate pollutants from the exhaust of a diesel engine, and also lowers the temperature of the emitted exhaust and of the shroud surrounding the pollution control  components  of  the device.   The system includes at least one combination catalytic converter  and  particulate  filter,  structured  to operate  at  a  sufficiently high temperature  as  to convert  potentially harmful  gaseous  pollutants  to innocuous  substances,  and which also collects and oxidizes carbon  and hydrocarbon  particles  in  the diesel exhaust to convert them to innocuous substances as well.  The catalytic converter(s) is contained in an  insulated  canister  for  containing  the  heat generated  by  the  catalytic  reactions,  with  the insulation  also  serving  to  lower  the  outside temperature of the canister.   A shroud is placed around the canister and other components,  with an axial fan blowing ambient air between the canister and shroud to reduce  the  exterior temperature  of  the shroud to an acceptable level.   The ambient air is mixed with the exhaust at the downstream end of the system, to lower the temperature of the exhaust gases to an acceptable level.   The system is particularly well  suited for use with diesel  engines  used  in enclosed environments, such as the underground mining industry, but may be structured for use with diesel engines operating in other environments as well.  A seamless, explosion proof shroud may also be used in environments where potential explosion hazards may exist, such as potentially explosive gases and dust in an underground mining environment.
