Description

Technical Field

[0001] The utility model relates to the technical field of catalytic combustion equipment, in particular to an exhaust gas catalytic combustion equipment. Background Technique

[0002] The catalytic combustion equipment refers to a device or equipment that burns under the action of a catalyst. The working principle of the catalytic combustion equipment is that with the help of a catalyst, the organic waste gas undergoes flameless combustion at a relatively low ignition temperature, decomposing the organic waste gas into non-toxic carbon dioxide and water vapor. Most of the catalytic combustion equipment is composed of devices such as a controller, a filtering device, a spray purification tower, a filter, and an activated carbon adsorption tower.

[0003] When the existing exhaust gas catalytic combustion equipment is in use, the exhaust gas is preliminarily treated by a spray purification tower, and then a filtering device is used to filter large-particle dust in the exhaust gas, thereby reducing impurities in the exhaust gas and improving the purity of the organic waste gas. However, this device needs to be used without shutdown, resulting in the filter screen of the filtering device being blocked and not easily replaced after long-term use, causing difficulties in subsequent exhaust gas filtration and affecting the subsequent overall catalytic combustion of the exhaust gas. Therefore, in view of the above problems, we propose an exhaust gas catalytic combustion equipment. Content of the Utility Model
