The catalytic combustion process in this example is as follows: the heating assembly 612 primarily heats the heating chamber 6112, the desorption waste gas enters the heating chamber 6112 from the air inlet communicating pipe 41 and flows from the lower part of the heating chamber 6112 to the upper part of the heating chamber 6112, so that the desorption waste gas gradually rises to the reaction temperature of 300 ℃., then enters the catalytic combustion chamber 6212 through the flow passage 300, under the action of the catalyst, the desorption waste gas is oxidatively decomposed into carbon dioxide and water, and releases a large amount of heat, finally the catalytic reaction temperature can reach 550 ℃, the hot gas flows through the upper heat exchange assembly 631 and the lower heat exchange assembly 632 to release the heat to the desorption waste gas which just enters the heating chamber 112, so that the desorption waste gas reaches the catalytic reaction temperature, at this time, the heating assembly 612 can be closed, the desorption waste gas is heated by the converted heat, the heat balance is realized, and the energy is saved. Meanwhile, the gas outlet 200 also generates heat under the action of the lower heat exchange assembly 632, so as to be used for other treatment processes, such as a desorption process, so that the heat is fully utilized.
