Description

Technical Field

[0001] This utility model relates to the technical field of environmental protection equipment, specifically to a volatile gas recovery and treatment device. Background Technology

[0002] Different industries employ different methods for VOCs recovery and utilization. Currently, adsorption is a common method, well-known for its suitability for treating waste gases with low concentrations and large volumes. The principle involves using porous materials such as activated carbon and zeolite to adsorb and recover VOCs from the waste gas. After adsorption saturation, the porous adsorbent material is then passed through a high-temperature steam reactor to introduce high-temperature steam for desorption, thus achieving the final goal of organic matter recovery. However, this method still suffers from low adsorption recovery efficiency and slow high-temperature steam desorption efficiency. The main reason is that most common porous adsorbent materials exhibit a stable structural form within the recovery tank, resulting in a small contact area with the waste gas to be recovered and the desorbed steam. Therefore, improving the fluidity of the porous adsorbent material within the recovery tank and increasing the contact area between the waste gas, steam, and porous adsorbent material are currently key to improving both adsorption recovery efficiency and high-temperature steam desorption efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a volatile gas recovery and treatment device that can effectively solve the problems existing in the background art.

[0004] To address the problems described in the background art, the present invention includes a recovery tank, which is a sealed cylindrical structure. A tee is located at the top of the recovery tank, with a waste gas pipe and a high-pressure steam pipe connected to the two inlet ends of the tee, respectively. Valves are installed on the waste gas pipe and the high-pressure steam pipe. A feed pipe for filling with porous adsorbent material is installed at the upper part of the recovery tank, and a discharge pipe for discharging filtered and desorbed waste gas is installed at the lower part of the recovery tank. A diversion tank, rotatable against its inner wall, is located at the top of the recovery tank. A bearing ring is installed at the bottom of the diversion tank and is fixedly mounted on the inner wall of the recovery tank. Several circumferentially distributed stirring shafts are installed at the bottom of the diversion tank. Each stirring shaft is a hollow tubular structure that communicates with the interior of the diversion tank. The bottom of each stirring shaft is vertically welded to a positioning plate, which can rotate against the inner wall of the recovery tank. A through hole is radially opened on each stirring shaft.

[0005] A drive unit is installed on one side of the recycling tank.

[0006] The bottom of the positioning disc is equipped with a concentric rotating shaft, and the end of the rotating shaft is equipped with a bearing seat, which is fixedly installed at the bottom of the recycling tank.

[0007] The drive device includes a first gear ring disposed on the outer circular surface of the diversion tank and a second gear ring disposed on the outer circular surface of the positioning plate, as well as a drive box mounted on the outer side of the recovery tank. The inner wall of the recovery tank is provided with a first tooth groove for the first gear ring to pass through and a second tooth groove for the second gear ring to pass through. A motor and reducer assembly is mounted on the top of the drive box. The power output shaft of the motor and reducer assembly extends into the drive box and is connected to the drive shaft via a coupling. A first drive gear and a second drive gear are fixedly mounted on the drive shaft. The first drive gear passes through the first tooth groove and meshes with the first gear ring, and the second drive gear passes through the second tooth groove and meshes with the second gear ring.

[0008] The top of the diversion tank is equipped with an air inlet pipe that communicates with its interior. The air inlet pipe is rotatably connected to a tee via a sealed bushing.
