Description

Technical Field

[0001] The utility model belongs to the technical field of industrial waste gas treatment, and more specifically, particularly relates to a device for secondary treatment of waste gas in an anodic oxidation process. Background Art

[0002] After the anodizing process of metal materials, acid and alkaline mist and other waste gases are produced. After the solid particles and moisture are removed by pre-treatment equipment, the remaining gases are generally treated by waste gas treatment methods such as adsorption, catalytic combustion, and biological methods to eliminate the harmful substances contained therein and meet the emission standards. Among them, the activated carbon adsorption box is a frequently used waste gas secondary treatment equipment. The existing activated carbon adsorption box is generally composed of a box body, an air inlet and outlet, honeycomb activated carbon for adsorbing harmful substances, and a drawer for holding the honeycomb activated carbon.

[0003] Existing application number: CN202121830676.5, in the technical field of waste gas treatment equipment of the utility model, an activated carbon adsorption box is disclosed, including a box body, a support grid arranged inside the box body, and an activated carbon adsorption layer, and an air inlet and an air outlet are opened at both ends of the box body; the support grid is arranged between the air inlet and the air outlet, and the support grid is fixedly connected to the box body, and the support grid is used to carry the activated carbon adsorption layer; the activated carbon adsorption layer includes a drawer filled with activated carbon adsorbent, and the drawer is spliced ​​by a plurality of independent sub-drawers. The utility model arranges the drawer used to carry the activated carbon adsorbent as a splicing of a plurality of independent sub-drawers, so that when the activated carbon in the drawer is replaced, the weight of a single drawer is distributed among a plurality of sub-drawers, which reduces the operation intensity when replacing the activated carbon at one time and reduces the labor intensity during a replacement operation.

[0004] Based on the above, after long-term use, the adsorption load of honeycomb activated carbon becomes larger. At this time, it is likely to drop carbon residue when subjected to the impact of exhaust gas. Especially when the drawer is pulled out to replace the activated carbon inside, the friction between the drawer and the adsorption box will cause shaking, which will further cause the loose carbon residue to fall. The carbon residue in the upper drawer will fall into the lower drawer, and the carbon residue in the bottom drawer will fall directly to the bottom of the activated carbon adsorption box. The staff needs to put tools into the adsorption box for cleaning, which is very troublesome. Utility Model Content
