Air cleaning catalytic oxidiser and ancillaries - using oil as fuel and comprises cold air blower, heat absorbing side of heat exchanger, heater, oxidn. reactor with catalyst, etc.

摘要

Air bearing a pollution load may be cleaned by catalytic oxidn. within a reactor. Units forming the air cleaning assembly are in the sequence: cold air blower for polluted air; heat absorbing side of the heat exchanger; heater; oxidn. reactor with catalyst; the venturi mixer; and heat surrendering section of the heat exchanger. The venturi mixer is co-located with blower burner flame tube; the channel between the venturi-mixer outlet and the surrendering side of the heat exchanger has a connection for the blower; sensors are a control circuit which links; heater upstream; before, between and after the catalyst; heater; blower burner and the blower. ADVANTAGE - Provides a reliable and economic air cleaning in an installation which may use oil as the fuel with no damage to catalyst during the warm-up phase.
