[0002] The catalytic combustion device is a purification device developed by utilizing the principle of catalytic oxidation and combining the advantages of heat storage combustion. It is suitable for the treatment of various industrial exhaust gases. The working principle of the existing catalytic combustion equipment is mainly as follows: the organic exhaust gas is flamelessly burned at a relatively low ignition temperature through the catalyst, so that the organic exhaust gas is decomposed into non-toxic carbon dioxide and water vapor. After the catalyst carrier is used for a long time, it is easy to be contaminated and needs to be replaced. Moreover, the catalyst carrier is fixed to the inside of the catalyst box.

The support arm 91 uses the pin shaft at its lower end as a fulcrum, and then presses the connecting shaft 92 backwards. The rear side of the front end panel of the catalyst box 4 contacts the front side of the box body 1. During the fixing process, a labor-saving lever structure will be formed, which has a good fixing effect on the catalyst box 4 and saves labor. When working, the controller 11 is adjusted, and the electric heating tube 2 generates heat to heat the surrounding air.

The industrial waste gas passes through the ventilation hole 82 upward, and then blows the fan blade 83. The fan blade 83 rotates under the action of the airflow to disturb the gas, so that the industrial waste gas can be evenly diffused and flowed upward. The electric heating pipe 2 heats the industrial waste gas, and the heating reaches When the ignition temperature of the catalyst reaches 200°C ~ 400°C, the high-temperature industrial waste gas passes through the strip holes at the bottom of the catalyst box 4 and the platinum-palladium precious metal catalyst inside. Under the action of the catalyst, the industrial waste gas undergoes an oxidation reaction to generate carbon dioxide and water. The treated industrial waste gas will pass upward through the air duct 62. The treated industrial waste gas preheats the industrial waste gas flowing inside the guide box 61 through the wall of the air duct 62, and then enters the upper end of the box body 1 and is discharged through the high-temperature resistant exhaust fan above. Before being discharged, the support plate 71, the disc pipe 72 and the heat conducting plate 73 are heated, thereby heating the air flowing inside the disc pipe 72, and performing two heat exchanges on the incoming industrial waste gas.
