Description

Technical Field

[0001] The utility model belongs to the technical field of tail gas treatment, in particular to a novel activated carbon adsorption device. Background Art

[0002] The tail gas generated by the chemical desulfurization process is usually treated by an activated carbon adsorption device. The existing activated carbon adsorption device weakens the adsorption effect of the activated carbon during use. During the replacement of the activated carbon, the tail gas generated by the chemical desulfurization process is easily caused to escape and pollute the air environment.

[0003] Example (authorization announcement number CN215610404U) A new type of activated carbon adsorption device, including a tank body, a wire mesh is arranged inside the tank body, an exhaust gas inlet is arranged on the side wall of the tank body below the wire mesh, an activated carbon box is arranged inside the tank body, the activated carbon box is located above the wire mesh, the activated carbon box includes an upper net and a lower net, and the top of the tank body has an exhaust gas outlet. This device integrates the steam-water separator with the activated carbon, which is convenient for reducing the water content of the exhaust gas entering the activated carbon box, effectively ensuring the adsorption capacity of the activated carbon, and reducing the frequency of replacing the activated carbon while ensuring the exhaust gas emission requirements, thereby reducing the cost of exhaust gas treatment and the labor intensity of the staff. However, this device does not take into account the weakening of the adsorption effect of the activated carbon after long-term use, and when the activated carbon is replaced, the exhaust gas generated by the chemical desulfurization process will escape and pollute the air environment.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The novel activated carbon adsorption device provides an adsorption effect on the tail gas generated by the chemical desulfurization process by arranging an adsorption component for storing activated carbon. The adsorption component is located on the side adjacent to two pairs of closed baffles, so that the two pairs of baffles can provide a shielding effect on the adsorption component to prevent the weakening of the adsorption effect of the activated carbon after long-term use. When the activated carbon is replaced, the tail gas generated by the chemical desulfurization inside the adsorption box will escape and pollute the air environment. The sealing block and the rotating rod cooperate with the adsorption component to separate the internal space of the adsorption box. The upper and lower threaded rods have reverse threads, so that the threaded block moves along the threaded path of the threaded rod. The two sliding rods move in reverse during the transmission process, thereby realizing the closing and opening of the two pairs of baffles.

[0015] The novel activated carbon adsorption device extends the connecting plate into the side wall of the adsorption box, and the connecting plate penetrates the side wall of the adsorption box, thereby extending the support frame into the interior of the adsorption box, and storing the activated carbon through the support frame and the support net, thereby achieving adsorption treatment of the tail gas generated by the chemical desulfurization process inside the adsorption box. The set rotating plate rotates to rotate and move the rotating plate to extend into the inner walls of the two U-shaped limit plates. Under the position restriction of the limit plate, the adsorption component is prevented from shaking, the structural stability of the device parts is improved, and the adsorption treatment effect of the tail gas generated by the chemical desulfurization process is improved. The set limit bearing fixes the rotation position of the rotating block, thereby fixing the position of the rotating plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0026] In order to solve the problem of tail gas emission from chemical desulfurization process and air pollution when replacing activated carbon in new activated carbon adsorption device, please refer to Figures 1 to 4The structure of the device body is an adsorption box 1, and an exhaust port 11 and an air guide port 12 are respectively installed at the top and bottom of the adsorption box 1. The air guide port 12 and the exhaust port 11 are respectively used to introduce and export the tail gas generated by the chemical desulfurization process into and out of the adsorption box 1, and perform tail gas adsorption treatment to prevent the tail gas generated by the chemical desulfurization process from being directly discharged and polluting the air environment. Sealing blocks 3 are welded at both ends of the inner wall of the adsorption box 1. Both end surfaces of the two sealing blocks 3 are fixedly connected to the adsorption box 1. The top of the sealing block 3 is rotatably connected to a rotating rod 4 through an opened through groove, and the end surface of the rotating rod 4 passes through the sealing block 3, and the side of the rotating rod 4 is sealed at the connection with the sealing block 3 to improve the tightness of the structure of the device parts. The top and bottom of the rotating rod 4 are fixedly connected to two threaded rods 5 with reverse threads.

[0027] The threaded rod 5 is threadedly connected with a threaded block 6, which is convenient for the two threaded blocks 6 at the upper and lower parts of the rotating rod 4 to move in opposite directions along the threaded path of the threaded rod 5. The adjacent sides of the two threaded blocks 6 at the same level are fixedly connected with sliding bars 7, thereby realizing the longitudinal reverse movement of the two sliding bars 7. The sides of the sliding bars 7 are slidably connected with two slide plates 8, which make the two slide plates 8 move along the path of the sliding bars 7. The end faces of the slide plates 8 are rotatably connected with baffle plates 9 through pin shafts, which is convenient for realizing the relative rotation of the baffle plates 9 and the slide plates 8. The two sliding bars 7 move in opposite directions, and the closing and opening of the two pairs of baffle plates 9 are realized under the pulling action of the slide plates 8. The adjacent sides of the two baffle plates 9 at the same level are respectively fixedly connected with sealing rubber strips that abut against each other, so as to improve their shielding and sealing effects.

[0028] The opposite sides of the two mutually closed baffle plates 9 are rotatably connected to the sealing block 3 through a pin shaft, and the four baffle plates 9 are rotatably connected to the side of a sealing block 3 in pairs, so as to realize the relative rotation of the baffle plates 9 and the sealing block 3. The side of the four threaded blocks 6 away from the slide rod 7 is in sliding friction contact with the inner wall of the adsorption box 1. The adjacent sides of the two pairs of closed baffle plates 9 are provided with adsorption components 2 for storing activated carbon. The two pairs of baffle plates 9 provide a shielding effect for the adsorption components 2 to prevent the exhaust gas generated by the chemical desulfurization process inside the adsorption box 1 from escaping and polluting the air environment when the activated carbon stored inside the adsorption component 2 is replaced.

[0029] The top ends of the two upper threaded rods 5 are fixedly connected to the output shaft of the rotating motor 10, and the fixed ends of the two rotating motors 10 are fixedly connected to the top surface of the adsorption box 1. The rotating motor 10 is provided to provide power to control the closing and opening of the two pairs of baffles 9 during the transmission process. The adsorption assembly 2 includes a support frame 13 and a support net 14. The support frame 13 and the support net 14 are used to store activated carbon. Both side surfaces of the support frame 13 are slidably connected to the sealing block 3. The internal space of the adsorption box 1 is separated by the support frame 13 and the support net 14 and the two sealing blocks 3, thereby improving the adsorption effect of the activated carbon on the exhaust gas generated by the chemical desulfurization process. The end face of the support frame 13 abuts against the inner wall of the adsorption box 1, the inner wall of the support frame 13 is fixedly connected to the support net 14, and the outer wall of the support frame 13 is fixedly connected to a connecting plate 15. The side of the connecting plate 15 is embedded and plugged into the adsorption box 1, and the connecting plate 15 passes through the side wall of the adsorption box 1.

[0030] The support frame 13 is extended into the interior of the adsorption box 1, and the connecting plate 15 is embedded and fixedly connected with a limit bearing 16 on the side away from the support frame 13. The inner ring of the limit bearing 16 is interference-fitted with a rotating block 17. The set limit bearing 16 fixes the rotation position of the rotating block 17, and a rotating plate 18 is welded on the end face of the rotating block 17. Two U-shaped limit plates 19 are slidably abutted at both ends of the side of the rotating plate 18. The outer wall of the adsorption box 1 is fixedly connected to the two U-shaped inverted limit plates 19, and the rotating plate 18 is rotated and moved into the inner wall of the limit plate 19. Under the position restriction of the two limit plates 19, the installation position of the adsorption component 2 is fixed to prevent it from shaking, thereby improving the structural stability of the device parts, and at the same time facilitating the disassembly of the adsorption component 2 and replacing the activated carbon stored in the adsorption component 2, thereby improving the convenience of using the device.

[0031] The rotating motor 10 is a prior art, and its working principle, size and model are irrelevant to the function of the present application, so no further description is given. The control method of the present invention is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0032] How it works

[0033] When using the novel activated carbon adsorption device, the user introduces the exhaust gas generated by the chemical desulfurization process into the adsorption box 1 through the air guide port 12 installed at the bottom of the adsorption box 1, and then adsorbs the activated carbon stored in the adsorption component 2 inside the adsorption box 1 to prevent the activated carbon from weakening due to long-term use. The two rotating motors 10 are started, and the output shafts of the rotating motors 10 rotate synchronously. The upper pair and the lower pair of threaded rods 5 have the same-direction threads, and the upper threaded rod 5 and the lower threaded rod 5 have reverse threads. By moving the threaded block 6 along the threaded path of the threaded rod 5, the reverse movement of the sliding rod 7 is achieved during the transmission process. The two pairs of baffles 9 are closed under the pushing action of the slide plate 8, so that the two pairs of baffles 9 provide a shielding effect for the adsorption component 2 to prevent the exhaust gas from escaping when the adsorption component 2 is disassembled and the activated carbon is replaced, thereby polluting the air environment. The provided sealing block 3 and rotating rod 4 provide sealing, shielding and transmission functions.

[0034] The tail gas generated by the chemical desulfurization process after adsorption is discharged from the adsorption box 1 through the exhaust port 11. The rotating plate 18 is rotated to release the sliding contact between the side of the rotating plate 18 and the inner wall of the limiting plate 19, and the lateral position fixation of the rotating plate 18 by the limiting plate 19 is released, so that the adsorption component 2 can be easily disassembled, and the activated carbon stored in the support frame 13 and the support net 14 can be replaced, thereby improving the convenience of using the device and improving the adsorption and cleaning effect of the adsorption device on the tail gas generated by the chemical desulfurization process. The limiting bearing 16 is provided to fix the rotation position of the rotating block 17, thereby fixing the position of the rotating plate 18, facilitating the relative rotation of the rotating plate 18 and the connecting plate 15, and improving the structural stability of the device parts.
