High-concentration malodorous gas catalytic oxidation deodorizing equipment and deodorizing method thereof

Abstract

The invention discloses high-concentration malodorous gas catalytic oxidation deodorizing equipment and a deodorizing method thereof. A shell is internally divided into an upper-layer area, a middle-layer area and a lower-layer area; a gas inlet pipeline is used for collecting malodorous gas to be treated and pre-mixing the malodorous gas and air so as to achieve preset malodorous gas concentration; the mixed gas enters a heat exchange area on the lower part of an airtight shell and enters a multi-way heat exchange pipeline so as to be preheated; the preheated gas to be treated is heated through a heating area so as to meet the conditions of catalytic combustion reaction temperature; the heated gas to be treated enters a catalytic reaction area so as to be subjected to catalytic combustion reaction, and malodorous gas molecules in the gas to be treated are combusted; and the reacted purified gas enters the zigzag heat exchange area, and is heat-exchanged with the untreated gas to be treated located in the heat exchange pipeline so as to be discharged out of the airtight shell through a gas outlet pipeline. The high concentration malodorous gas catalytic oxidation deodorizing equipment provided by the invention is of an integral structure, can be used for realizing preheating, heating and catalytic combustion reaction of the gas to be treated, and is compact in structure; the heat energy of the gas after being catalytic combusted is effectively utilized, so that the energy consumption is reduced; and the cleanness treatment of the malodorous gas is realized through catalytic combustion.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a high-concentration malodorous gas catalytic oxidation deodorization device and a deodorization method thereof, which are suitable for the treatment and treatment of organic waste gas and odor generated in workshops such as domestic garbage, kitchens, and sludge treatment. purify. Background technique [0002] Domestic garbage, kitchen, and sludge treatment workshops will generate a lot of odor during the treatment process, which will affect the atmospheric environment and the health of the staff. At present, the methods used for odor treatment are adsorption method, combustion method and biological deodorization method. The number of equipment is large, the equipment layout is scattered, and the floor area is large. [0003] The invention adopts a catalytic combustion method, uses a catalyst to reduce the combustion temperature of the odor, oxidizes ...
