Catalytic combustion system and catalytic combustion method

Abstract

The invention provides a catalytic combustion system and a catalytic combustion method. The catalytic combustion system comprises an exhaust gas inlet, a chimney, a catalytic combustion device and an adsorption device, wherein the exhaust gas inlet is connected to a filter through a pipeline and then is connected to an upper gas inlet of an adsorption bed through a pipeline, and an adsorption draught fan is connected to a lower gas outlet of the adsorption bed through a pipeline; an upper gas outlet of the adsorption bed is connected to a heat exchanger of the catalytic combustion device through a pipeline; the heat exchanger is connected to a gas outlet of a catalytic combustion draught fan through a pipeline; a gas inlet of the catalytic combustion draught fan is connected to the exhaust gas inlet through a pipeline; and the heat exchanger is connected to the chimney through a pipeline. The catalytic combustion method provided by the invention has the beneficial effects that filtration, active carbon adsorption, hot gas flow desorption and catalytic combustion are combined together to form an effective exhaust gas treatment process, the exhaust gas treatment efficiency is greatly improved, external energy sources required for treating exhaust gases are effectively saved, and secondary emission pollution is completely eradicated.

Description

technical field [0001] The invention relates to waste gas treatment equipment and methods, in particular to a catalytic combustion system and a catalytic combustion method. Background technique [0002] There are many types of organic waste gas, complex composition, and various concentrations, so its treatment is more difficult. 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 catalytic combustion method is widely used. The organic waste gas is burned at a certain temperature and catalyzed by a catalyst to convert the organic waste gas into CO2 and H2O. In the existing catalytic combustion device...
