Catalytic combustion bed and catalytic combustion method thereof

Abstract

The invention discloses a catalytic combustion bed and a catalytic combustion method thereof, relating to the fields of waste gas treatment equipment and methods. A lower air outlet of a heat exchanger I is connected with an air inlet of a flame arrester, an air outlet of the flame arrester is connected with a lower air inlet of a catalytic decomposition bed, a lower air outlet of the catalytic decomposition bed is connected with an upper air inlet of the heat exchanger I, and an upper air outlet of the heat exchanger I is connected with a wind inlet of an induced air fan; and a wind outlet of the induced air fan is connected with an upper air inlet of a heat exchanger II, an upper air outlet of the heat exchanger II is connected with a chimney, an upper air inlet of the catalytic decomposition bed is connected with an air outlet of an air heater, an air inlet of the air heater is connected with a lower air outlet of the heat exchanger II, a lower air inlet of the heat exchanger II is connected with a wind outlet of a blower, and a wind inlet of the blower is connected with an air filter. The catalytic combustion bed has the beneficial effects that the problem that light flammable and combustible organic exhaust gas enters an electric heating system to explode is solved, and meanwhile, the operation cost of the system is lowered.

Description

technical field [0001] The invention mainly relates to the field of waste gas treatment equipment and methods, in particular to a catalytic combustion bed and a catalytic combustion method thereof. Background technique [0002] Organic waste gas treatment refers to the treatment work of adsorption, filtration and purification of organic waste gas generated in the process of industrial production. Difficulties in the treatment of organic waste gas: Organic waste gas is generally flammable, explosive, toxic and harmful, and difficult to deal with. At present, the purification and treatment processes adopted by organic waste gas purification devices include catalytic combustion method, activated carbon adsorption method, condensation method, absorption method and plasma oxidation method, etc., which solve the pollution of organic waste gas to the environment to a certain extent, but the above purification and treatment devices are also There are many problems. [0003] The ca...
