The adsorption bin 5 also includes: a motor 504, a lower strong magnetic block 505, a moving block 506, a roller 507, an upper strong magnetic block 508, a brush strip 509, a reciprocating screw rod 510, a guide rod 511, and a cam 512. The motor 504 is fixedly connected to the bottom of the adsorption bin housing 501, the moving block 506 is slidably connected to the inner wall of the adsorption bin housing 501, the roller 507 is rotatably connected to the inner wall of the bottom of the moving block 506, the reciprocating screw rod 510 is fixedly connected to the output end of the motor 504, the inner wall of the lower strong magnetic block 505 is movably connected to the circumferential surface of the reciprocating screw rod 510, the brush strip 509 is fixedly connected to the bottom of the moving block 506, the upper strong magnetic block 508 is fixedly connected to the inner wall of the moving block 506, the guide rod 511 is fixedly installed at the bottom of the adsorption bin housing 501 through a bracket, and the cam 512 is fixedly connected to the end of the reciprocating screw rod 510 away from the motor 504. Working principle: The combustion exhaust gas after desulfurization and denitrification treatment enters the adsorption bin 5 through the exhaust pipe 8. At this time, the material pump 2 is started to extract the activated carbon powder from the silo 3 and spray it out through the nozzle 503. The high-temperature and high-pressure exhaust gas drives the mixing fan 502 to rotate. The rotation of the mixing fan 502 makes the sprayed activated carbon powder and the exhaust gas fully mixed, effectively absorbing the odor and harmful substances such as dioxins and mercury. At the same time, the motor 504 is started, and the rotation of the motor 504 drives the reciprocating screw 510 to rotate. The rotation of the reciprocating screw 510 drives the strong magnetic block 50 Since the lower strong magnetic block 505 is constrained by the guide rod 511, the lower strong magnetic block 505 can only reciprocate along the direction of the guide rod 511. The lower strong magnetic block 505 attracts the upper strong magnetic block 508 to move through magnetic force, and the movement of the upper strong magnetic block 508 drives the moving block 506 to move. The moving block 506 is kept at a certain height in the adsorption bin housing 501 by the roller 507 at the bottom and reciprocates. When the moving block 506 moves, the brush bar 509 brushes the activated carbon deposited on the inner wall of the adsorption bin housing 501 into the filter bin 6 to prevent excessive accumulation of materials.

The push rod 608 is slidably connected to the left side of the filter bin housing 601, and the rotating wheel 609 is rotatably connected to the left side of the discharge plate 604 through the connecting rod. The inner wall of the rotating wheel 609 is rotatably connected to the circumferential surface of the connecting rod, the push rod 608 contacts the rotating wheel 609, and the inner wall of the lock buckle 603 is clamped. On the outer wall of the convex block at the rear of the discharge plate 604, the brush rod 605 is located on the motion trajectory of the filter plate 602. The carbon absorption pool 7 also includes: a pool body 701, a motor bracket 702, a motor 2 703, and an air pipe 708. The pool body 701 is fixedly mounted on the top of the base 1, the motor bracket 702 is fixedly mounted on the top of the base 1, the motor 2 703 is fixedly connected to the top of the motor bracket 702, and the air pipe 708 is fixedly connected to the inner wall of the pool body 701. The carbon absorption pool 7 also includes: a collecting cylinder 704, a sieve plate 705, a fixing cylinder 706, storage barrel 707, receiving barrel 704 is fixedly connected to the output end of motor 2 703, there are four sieve plates 705, and the four sieve plates 705 are fixed on the circumferential surface of receiving barrel 704, the fixed barrel 706 is fixedly connected to the inner wall of the pool body 701, the circumferential surface of storage barrel 707 is slidingly connected to the inner wall of fixed barrel 706, the inner wall of receiving barrel 704 is rotatably connected to the circumferential surface of fixed barrel 706, the circumferential surface of air pipe 708 is provided with a number of small holes, and air pipe 708 is fixedly connected to the right side of the filter bin shell 601.
[0020] Working principle: The harmful activated carbon powder that has absorbed the exhaust gas enters the filter chamber 6. After the filtration is completed, the filter plate 602 needs to be replaced. When the filter plate 602 is pulled out, the filter plate 602 contacts the friction wheel 606 to drive the friction wheel 606 to rotate. The rotation of the friction wheel 606 drives the brush rod 605 to rotate. The rotation of the brush rod 605 brushes off the waste accumulated on the filter plate 602, effectively improving the defect that the waste is scattered everywhere along with the filter plate 602. After the filtration is completed, the waste needs to be discharged. Open the lock 603 and the discharge plate 604 falls to the top of the base 1. At this time, the cam 512 is driven by the reciprocating screw 510 drives the rotation, and the cam 512 rotates to push the push rod 608 to move toward the discharge port. The push rod 608 contacts the runner 609 and continues to push. The runner 609 will move upward along the arc groove of the outer wall of the filter bin shell 601. The movement of the runner 609 drives the discharge plate 604 to move upward along the arc groove of the outer wall of the filter bin shell 601. When the protrusion of the cam 512 is away from the push rod 608 and does not contact it, the discharge plate 604 will fall back to the bottom due to the material and its own weight. The reciprocating up and down shaking of the discharge plate 604 will improve the discharge efficiency and improve blockage.
[0021] After the exhaust gas is filtered, it enters the bottom of the carbon absorption pool 7 through the air pipe 708. The carbon absorption pool 7 is provided with lime water as a carbon dioxide absorbent. The absorbent absorbs carbon dioxide and reacts with it to form a precipitate. At this time, the motor 2 703 is started to drive the receiving barrel 704 to rotate. The rotation of the receiving barrel 704 drives the sieve plate 705 to rotate. The sieve plate 705 rotates and stirs to improve the adsorption efficiency of the adsorbent while picking up the reactant residue. When it rotates to a certain angle, the residue falls into the receiving barrel 704 through the gap on the circumferential surface of the fixed barrel 706. The storage barrel 707 can be pulled out to clean it and collect and process the precipitate. The treated harmless gas is discharged through the exhaust pipe 8.
