Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to an activated carbon adsorption device for waste gas treatment. Background Technique

[0002] Activated carbon adsorption devices are commonly used in waste gas treatment and are the best purification equipment for treating organic waste gas and odor treatment. Common ones include activated carbon adsorption towers. Activated carbon adsorption towers have the advantages of high adsorption efficiency, wide application range, convenient maintenance, and the ability to treat various mixed waste gases. When common activated carbon adsorption towers input waste gas through the air inlet, the phenomenon of uneven air supply is likely to occur, resulting in uneven utilization rates of the activated carbon adsorption blocks in the activated carbon box, affecting the treatment effect of the activated carbon box on waste gas. In addition, common activated carbon adsorption towers are not convenient for installing and disassembling the activated carbon box, which consumes a relatively long time for installation and disassembly, and it is difficult to clean the activated carbon adsorption blocks in the activated carbon box.

[0003] The utility model patent with the authorization announcement number CN210495793U discloses an activated carbon adsorption device for waste gas treatment. The utility model includes a housing and two activated carbon boxes. The middle parts of both sides of the housing are respectively provided with an air inlet and an air outlet. A air distribution plate is fixedly installed inside the housing, and a number of air holes are evenly arranged on the surface of the air distribution plate. The inner walls of the top and bottom of the housing are both fixedly provided with two symmetrically arranged sliding grooves, and the four sliding grooves are respectively slidably connected with the pulleys fixedly installed at both ends of the two activated carbon boxes. For the activated carbon adsorption device for waste gas treatment of the utility model, by setting two activated carbon boxes, the waste gas can be adsorbed doubly, improving the adsorption effect on the waste gas. By installing an air distribution plate inside the housing, after the waste gas passes through the air inlet, the air holes on the air distribution plate can evenly transmit the waste gas to the two activated carbon boxes, enabling the activated carbon adsorption blocks in the two activated carbon boxes to evenly adsorb the waste gas, ensuring the treatment effect on the waste gas.

[0004] Although the above utility model can adsorb waste gas doubly and can conveniently disassemble the activated carbon box, the above utility model cannot conveniently take out the activated carbon blocks from the activated carbon box for cleaning. Due to the different carbonization degrees and production processes of the activated carbon blocks, the brittleness and hardness are different. Taking out the activated carbon from the activated carbon box in the above utility model may cause the activated carbon to break. In view of this, we propose an activated carbon adsorption device for waste gas treatment. Content of the Utility Model

An activated carbon box 13 is installed between the installation grooves 12. A rotating cover 14 is rotatably connected to the front end of the activated carbon box 13. A rotating groove 133 is opened at the front end of the lower surface of the activated carbon box 13. A support mechanism 132 is placed on the lower side inside the activated carbon box 13. Activated carbon blocks 131 are placed on the support mechanism 132. Through the above mechanism, the two activated carbon blocks 131 as a whole can be conveniently taken out of the activated carbon box 13.

[0030] Furthermore, the support mechanism 132 includes a support platform 1321, support plates 1322 welded to the left and right sides of the lower surface of the support platform 1321, and baffles 1323 welded to the left and right ends of the upper surface of the support platform 1321. The activated carbon blocks 131 are limited by the baffles 1323.

[0031] Furthermore, an auxiliary groove 141 is formed in the middle of the upper end of the front side surface of the rotating cover 14, limiting grooves 142 are formed on both the left and right sides of the rear side surface of the rotating cover 14, a rotating rod 143 is rotatably connected to the lower side inside the rotating cover 14, and the rotating cover 14 is rotatably connected in the rotating groove 133 through the rotating rod 143.

[0032] In this embodiment, a gap is left between the activated carbon blocks 131 and the inner side wall of the activated carbon box 13, and the top ends of the activated carbon blocks 131 are in contact with the upper surface of the inner wall of the activated carbon box 13, ensuring that the gas passing through the activated carbon box 13 will be cleaned by the activated carbon blocks 131.

[0033] In this embodiment, a flange is provided on the side surface of the front cover 3, and a sealing ring is provided between the flange of the front cover 3 and the contact surface of the adsorption box 1 to increase the sealing performance.

[0034] In this embodiment, the distance between the support plates 1322 is equal to the distance between the limiting grooves 142, and the right end of the lower side surface of the support plate 1322 is processed with an inclined chamfer to facilitate the support plate 1322 to enter the activated carbon box 13 from the limiting groove 142.

[0035] In this embodiment, the contact surfaces between the support plates 1322 and the limiting grooves 142 are smooth, and the rotating rod 143 is welded to the left and right side surfaces of the rotating groove 133 to reduce the friction force of the contact surfaces.
