  • Exhaust gas treatment unit
    Patent number: 5891404
    Abstract: An exhaust gas treatment unit of the combustion type is capable of effectively carrying out the decomposing treatment of an exhaust gas while at the same time allowing the unit to be reduced in size. The exhaust gas treatment unit includes a treatment drum, a combustion air introduction tube attached at one end of the treatment drum to introduce combustion air to the inside of the treatment drum, a fuel gas introduction tube disposed inside the combustion air introduction tube to introduce fuel gas to the inside of the treatment drum, and an exhaust gas introduction tube disposed inside the fuel gas introduction tube to introduce exhaust gas to the inside of the treatment drum. A flame tube extends from an end portion of the combustion air introduction tube on the air outlet side to the vicinity of the other end of the treatment drum, and a cooling air introduction port is provided for introducing cooling air into a space between the side wall of the treatment drum and the flame tube.

  • Exhaust gas treatment unit and method
    Patent number: 5800792
    Abstract: The present invention relates to an exhaust gas treatment unit which possesses a stable treating capacity, with a reduced running cost. The exhaust gas treatment unit removes noxious gases such as monosilane contained in an exhaust gas by thermal decomposition. The exhaust gas treatment unit includes a heating drum (5) into which the exhaust gas and oxygen or air are introduced and a heating source (6) disposed on the outer periphery of the heating drum (5) so as to heat the inside of said heating drum (5). A temperature sensor (14) detects the temperature of the inside of said heating drum (5) in the vicinity of its outlet and a controller (16) controls the heating source (6) in accordance with a detected temperature value from the temperature sensor (14) so that the temperature of the inside of said heating drum (5) in the vicinity of the outlet is maintained within a predetermined temperature range.
