Description

TECHNICAL FIELD

[0001] The utility model relates to waste gas catalytic combustion technical field, specifically related to a catalytic combustion equipment for waste gas treatment. BACKGROUND

[0002] The catalytic combustion equipment utilizes the catalytic action of the catalyst to oxidize and decompose the harmful substances in the waste gas at a relatively low temperature, converting them into harmless carbon dioxide and water vapor. Its working principle is mainly based on catalytic oxidation reaction, that is, under the action of the catalyst, the harmful substances in the organic waste gas chemically react with oxygen in the air to generate harmless substances.

[0003] In the prior art, the catalyst in the catalytic combustion equipment is in a static state. Since the catalyst is stationary, the waste gas often cannot fully contact the catalyst accumulated inside when passing through the catalytic combustion equipment. This insufficient contact results in the inability of the catalyst to effectively catalyze and decompose the harmful substances in the waste gas, thereby reducing the purification efficiency of the catalytic combustion equipment. In addition, the static state of the catalyst can also cause poor flow of the waste gas inside the equipment, generating local vortex or dead angle, further affecting the treatment effect of the waste gas.
