Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for carbon source production. Background Art

[0002] Waste gases generated during biocarbon source production primarily come from the pyrolysis or carbonization of biomass. During this process, biomass feedstock undergoes pyrolysis at high temperatures in the absence or absence of oxygen, producing biochar, bio-oil, and non-condensable gases. Activated carbon plates are porous carbonaceous materials with a highly developed pore structure and a large specific surface area, resulting in excellent adsorption properties. Therefore, activated carbon plates are often used to adsorb waste gases from carbon source production to prevent them from being released into the environment and causing adverse effects.

[0003] However, the adsorption capacity of the activated carbon plate has a certain limit. After the activated carbon plate adsorbs harmful substances in the exhaust gas to saturation, the activated carbon plate's ability to treat the exhaust gas weakens and the activated carbon plate needs to be replaced. Currently, when replacing the activated carbon plate, it is necessary to stop the exhaust gas transportation, which will reduce the efficiency of exhaust gas treatment. Summary of the Invention

[0004] The utility model aims to solve the problem that the replacement of activated carbon plates used to treat waste gas from carbon source production affects waste gas treatment, and provides a waste gas treatment device for carbon source production, which can replace the activated carbon plates without stopping the machine, thereby improving the waste gas treatment efficiency.

[0009] Furthermore, the front and rear ends of the rotating plate in the front connecting tube are arc-shaped surfaces with convexities facing each other, and the left and right ends of the rotating plate in the rear connecting tube are arc-shaped surfaces with convexities facing each other.

[0010] Furthermore, when the rotating plate in the front connecting tube contacts the inner wall of the connecting tube and the rotating plate in the rear connecting tube is perpendicular to the corresponding rotating plate on the front side, each slider contacts the inner bottom of the inclined groove in which it is located, the front connecting tube is in a blocked state, and the rear connecting tube is in an open state; the upper end of each rotating rod is connected to a limit plate, and when the movable plate moves upward to contact each limit plate, the slider moves upward with the movable plate to the limit state, and each slider presses against the inclined groove in which it is located to drive the rotating rod to rotate 90 degrees.

The rotating rod 5 is a round rod body, and an inclined groove 6 is provided on the peripheral wall of the rotating rod 5 extending out of the connecting tube 2. The cross-section of the inclined groove 6 is rectangular, and the upper end of each inclined groove 6 penetrates the top surface of the rotating rod 5. The movable plate 4 is a rectangular plate body, and a circular hole 7 corresponding to each rotating rod 5 is provided on the movable plate 4. The upper end of each rotating rod 5 passes through the corresponding circular hole 7. Each circular hole 7 is provided with a slider 8 extending into the inclined groove 6 on the corresponding rotating rod 5. The slider 8 is a rectangular block that is in sliding contact with the inclined groove 6. The movable plate 4 is driven by a screw 9 to move upward or downward.

[0023] The lower end opening of the connecting pipe 2 is blocked by a sealing plate 10 , and the two connecting pipes 2 are in a front-to-back symmetric state; the adsorption plates on the two connecting pipes 2 are in a front-to-back symmetric state.

[0024] A through hole 11 is vertically provided in the middle of the front side plate of the connecting pipe 2 on the front side; the adsorption plate on the front side includes a supporting frame 12 and a connecting plate 14, an activated carbon plate 13 is fixed in the supporting frame 12, and the front end of the supporting frame 12 is connected to the connecting plate 14, the supporting frame 12 and the activated carbon plate 13 extend into the connecting pipe 2 through the through hole 11, the inner wall of the connecting pipe 2 contacts the supporting frame 12, and the connecting plate 14 is located outside the connecting pipe 2 and is connected to the front side plate of the connecting pipe 2 via bolts 15.

[0025] The front and rear ends of the rotating plate 3 in the connecting tube 2 on the front side are arc-shaped surfaces with convexities facing each other, and the front and rear ends of the rotating plate 3 in the connecting tube 2 on the front side contact the front and rear inner walls of the connecting tube 2. The left and right ends of the rotating plate 3 in the connecting tube 2 on the rear side are arc-shaped surfaces with convexities facing each other.

[0026] When the rotating plate 3 in the front connecting tube 2 contacts the inner wall of the connecting tube 2 and the rotating plate 3 in the rear connecting tube 2 is perpendicular to the corresponding rotating plate 3 on the front side, each slider 8 contacts the inner bottom of the inclined groove 6 in which it is located, the front connecting tube 2 is in a blocked state, and the rear connecting tube 2 is in an open state; the upper end of each rotating rod 5 is connected to the limit plate 16, and when the movable plate 4 moves upward to contact each limit plate 16, the slider 8 moves upward with the movable plate 4 to the limit state, and each slider 8 presses the inclined groove 6 in which it is located to drive the rotating rod 5 to rotate 90 degrees.
