Description

Technical Field

[0001] This utility model relates to the field of CO catalytic combustion furnace technology, specifically a CO catalytic combustion device. Background Technology

[0002] VOCs are toxic organic waste gases, and direct emission will cause air pollution. VOCs can be decomposed into CO2 and H2O at high temperatures using CO as a catalyst, thus avoiding VOCs pollution of the air. CO catalytic combustion furnace is required when purifying VOCs. CO catalytic combustion equipment is a highly efficient and environmentally friendly combustion treatment technology. Its process principle is to use a catalyst to convert the combustible components in organic waste gas into carbon dioxide and water, while releasing a large amount of heat.

[0003] For example, utility model patent CN222992915U discloses a CO catalytic combustion device, relating to the field of CO catalytic technology. It includes a main connecting base plate for the combustion device, a protective shell fixedly connected to one side of the main connecting base plate, a connecting block fixedly connected to one side of the protective shell, a motor fixedly connected to one side of the connecting block, a mounting plate fixedly connected to the output shaft of the motor via a coupling, an output pipe main structure fixedly connected to one side of the mounting plate, a fixing block fixedly connected to one side of the output pipe main structure, and a burner fixedly connected to one side of the fixing block. This utility model, through the catalytic bed fixedly connected to one side of the output pipe main structure, the air inlet pipe, the filter, the fixing block inside the catalytic bed and the output pipe main structure, and the burner, facilitates efficient CO catalytic combustion for users. However, there is a problem that impurities on the filter are inconvenient to clean after long-term use, resulting in poor filtration effect and ultimately reducing the amount of air passing through the filter, thus reducing the efficiency of CO catalytic combustion. Therefore, we propose a CO catalytic combustion device. Utility Model Content

[0033] Working principle: When replacing the filter body 14, the bidirectional electric push rod 72 can be activated.

The first pulley 735 drives the second pulley 737 to rotate via the belt 736. The second pulley 737 drives the second follower shaft 738 to rotate. The second follower shaft 738 drives the rotating plate 7310 to rotate. The rotating plate 7310 drives the limiting plate 7311 to rotate outward. At this time, the two limiting plates 7311 release their clamping action on the filter body 14.
