Patent ID: 7507084

Claim:
A Regenerative Fume Incinerator for cleaning a polluted gas, the Regenerative Fume Incinerator comprising: a combustion chamber which receives the polluted gas and oxidizes the oxidizable pollutants therein to produce a cleansed gas; and a plurality of regenerative heat exchangers, each regenerative heat exchanger comprising a regenerative heat exchanger compartment having a hot end and a cold end, the hot end of the regenerative heat exchanger compartment configured for fluid communication with the combustion chamber, the regenerative heat exchanger compartment further comprising a heat sink media bed located in between the hot and cold ends of the regenerative heat exchanger compartment in the path of flow of the polluted gas and the cleansed gas and a deposited matter removal means for dislodging deposited matter from the surface of the heat sink media within the regenerative heat exchanger compartment, the deposited matter removal means comprising at least one spray pipe containing a cleaning fluid, the cleaning fluid being at a pressure greater than the gas pressure within the regenerative heat exchanger compartment, the spray pipe located within the heat sink media bed to direct the cleaning fluid therein toward at least some of the surfaces of the heat sink media to physically dislodge the deposited matter thereon, the cleaning fluid flowing from a hot zone of the heat sink media bed to a less hot zone of the heat sink media bed, and a flow control means for the selective introduction of the polluted gas into the regenerative heat exchanger compartment and for the selective removal of the cleansed gas from the regenerative heat exchanger compartment, the flow control means being located at the cold end of the regenerative heat exchanger and configured for fluid communication with the cold end of the regenerative heat exchanger compartment.
