Description

Technical Field

[0001] The utility model relates to the technical field of catalytic combustion CO furnaces, in particular to a novel catalytic combustion CO furnace. Background Art

[0002] Catalytic combustion is the combustion of combustibles under the action of a catalyst. Compared with direct combustion, catalytic combustion has a lower temperature and is more complete. The catalyst used in catalytic combustion is a multi-component substance of precious metals and metal oxides with a large specific surface area. Using an appropriate catalyst is one of the combustion methods that decomposes and oxidizes combustible substances in harmful gases at a lower temperature.

[0003] When the catalysts in the current CO furnace are stacked and used, there are tiny gaps between adjacent catalysts, which affects the gas exhaust effect of the CO furnace. In addition, the CO furnace generally uses an inspection port to inspect and maintain the internal components of the furnace body, and there is a gap between the traditional furnace door and the furnace port, so that harmful gases in the catalytic combustion process will leak from the gap into the surrounding environment, resulting in incomplete exhaust gas treatment and low treatment efficiency.
