[0044] Working principle:

[0045] First, the plasma purifier 16 is turned on through the power distribution control box 15, and then the injection drive fan 17 is turned on through the power distribution control box 15. Then, the exhaust gas enters the pretreatment air chamber 22 through the exhaust gas guide pipe 18 and the injection drive fan 17 under the drive of the injection drive fan 17. Then, the exhaust gas enters the corresponding pretreatment filter element 23 through the tapered through hole 50 and the external threaded butt joint 54 at the top of the plugging sealing column 44. Then, the smoke and dust in the exhaust gas are intercepted by the pretreatment filter element 23 inside. Then, the exhaust gas passes through the small holes on the pretreatment filter element 23 and enters the gas retention groove 45. Then, the exhaust gas passes through the downflow upper channel 73, the upper spherical groove 72, the downflow permeable chamber 71, the bypass slit gas groove 76, and the downflow lower pipe 75 to enter the collecting air pipe 46, and then the exhaust gas The exhaust gas enters the cavity on the left side of the chamber isolation vertical plate 33 inside the plasma treatment box 11 through the universal joint pipe 47 and the rotary air guide pipe 35, and then the exhaust gas is redistributed through the exhaust gas uniform distribution hole 34 and blown to the plasma purifier 16, and then the exhaust gas passes through the plasma purifier 16, and then the plasma purifier 16 purifies the exhaust gas to form clean gas, and then the clean gas is discharged through the tapered pipe 13 and the butt joint 14, and then the front pressure sensor 31 detects the air pressure inside the pretreatment air chamber 22 in real time, and then the rear pressure sensor 32 detects the air pressure in the cavity on the left side of the chamber isolation vertical plate 33 inside the plasma treatment box 11 in real time, and then the front pressure sensor 31 and the rear pressure sensor 32 send the data to the power distribution control box 15 , then the power distribution control box 15 calculates the difference between the two data and compares the difference with the maximum value preset inside. When the difference is less than the maximum value, it indicates that the permeability of the pre-treatment filter element 23 is good and it can continue to be used. When the difference is greater than the maximum value, it indicates that the permeability of the pre-treatment filter element 23 is poor and the pre-treatment filter element 23 needs to be replaced. At this time, the power distribution control box 15 controls the replacement drive motor 84 to run, and then the replacement drive motor 84 drives the reciprocating screw 85 to rotate, and then the reciprocating displacement block 86 moves downward under the action of the threaded cooperation between it and the reciprocating screw 85, and then the reciprocating displacement block 86 drives the straightening sliding plug plate 87 to move downward, and then the straightening sliding plug plate 87 drives the linkage displacement block 89 to move downward through the linkage vertical slide rod 88, and then the linkage The displacement block 89 drives the ratchet head 80 to move downward, and then drives the ratchet head 80 to drive the collecting air pipe 46 to rotate through the one-way meshing between it and the replacement ratchet gear 82, and then the non-return spring piece 94 slides on the surface of the replacement ratchet gear 82 and prevents the replacement ratchet gear 82 from rotating in reverse, and then the collecting air pipe 46 rotates with the blocking sealing column 44, and then the blocking sealing column 44 rotates an angle with the pre-treatment filter element 23 through the gas retardation groove 45, and then the pre-treatment filter element 23 located at the leftmost end of the pre-treatment air chamber 22 passes through the tapered accommodating hole 41 into the arc surface sealing groove 42, and then the inner wall of the arc surface sealing groove 42 blocks the corresponding tapered through hole 50, thereby disconnecting the pre-treatment filter element 23 from the pre-treatment air chamber 22. At the same time,The pretreatment filter element 23 on the far right inside the arc surface sealing groove 42 is turned upward under the drive of the blocking sealing column 44, and then the end of the pretreatment filter element 23 gradually tilts upward, and then the counterweight lead block 26 inside it brings the cleaning columnar brush 27 close to the collecting air pipe 46 under the action of gravity, and then the counterweight lead block 26 moves to the extreme position inside the pretreatment filter element 23, and then the corresponding non-return smooth ball 77 slides along the downflow permeable chamber 71 to the inside of the lower spherical groove 74 under the action of gravity, and then the upper spherical groove 72 and the downflow upper channel 73 are opened, and then the pretreatment filter element 23 passes through the tapered accommodating hole 41 and is connected with the pretreatment air chamber 22 through the tapered through hole 50, so that a pretreatment filter element 23 is completed. The replacement of the linkage displacement block 89, at this time, moves downward to the dead point position, and then the reset displacement block 86 moves upward under the action of the threaded cooperation between it and the reciprocating screw 85, and then the reset displacement block 86 moves upward with the driving ratchet head 80 through the straightening slide plate 87, the linkage vertical slide rod 88, and the linkage displacement block 89, and then the driving ratchet head 80 applies a reverse thrust to the replacement ratchet gear 82, and then the anti-return spring piece 94 clamps the replacement ratchet gear 82 in one direction, so that the replacement ratchet gear 82 cannot rotate in the opposite direction, and then the replacement ratchet gear 82 applies pressure to the inclined surface of the driving ratchet head 80, and then the driving ratchet head 80 moves toward the inside of the anti-return chamber 91, and then the driving ratchet head 80 pushes the anti-return slider 93 to move synchronously, and then the anti-return slider 93 squeezes The check spring 92 is then elastically compressed, and the elastic potential energy increases. Then the difference in the detection data of the front pressure sensor 31 and the rear pressure sensor 32 becomes smaller, and then the pretreatment filter element 23 connected to the pretreatment air chamber 22 is replaced one by one according to the above principle, and then the difference gradually decreases until the difference is less than the minimum value preset inside the power distribution control box 15. At this time, the power distribution control box 15 controls the replacement drive motor 84 to stop. During this process, the pretreatment filter element 23 on the rotation direction of the blocking sealing cylinder 44 gradually tilts downward, and the corresponding downflow permeability mechanism 7 gradually tilts downward, and then the check smooth ball 77 slides downward along the downflow permeability chamber 71 under the action of gravity, and then the check smooth ball 77 enters the upper spherical groove 72, and then The anti-return smooth ball 77 blocks the upper spherical groove 72 and the downflow upper channel 73 to prevent exhaust gas leakage. Then, the counterweight lead block 26 slides obliquely downward inside the pre-treatment filter element 23 with the cleaning columnar brush 27 under the action of gravity. Then, the cleaning columnar brush 27 pushes the smoke and dust inside the pre-treatment filter element 23 to move obliquely downward. At the same time, the cleaning columnar brush 27 cleans the inner wall of the pre-treatment filter element 23 to brush off the smoke and dust on the inner wall of the pre-treatment filter element 23. After that, the pre-treatment filter element 23 is connected with the dust collecting groove 24 through the tapered through hole 50 and aligned with the dust collecting box 25. Then, the smoke and dust inside the pre-treatment filter element 23 pass through the tapered through hole 50 under the push of the cleaning columnar brush 27 and fall into the dust collecting box 25.Then the plugging sealing cylinder 44 continues to rotate with the pre-treatment filter element 23, and then the filter element locker 5 corresponding to the pre-treatment filter element 23 is exposed through the arc surface maintenance groove 43, and then the exhaust gas is continuously purified according to the above principle. Then, as the use time increases, the filtering performance of the pre-treatment filter element 23 gradually decreases. When the pre-treatment filter element 23 needs to be replaced, the force disc 65 is pulled, and then the force disc 65 is operated to move the vertical pull rod 64 outward, and then the vertical pull rod 64 is operated to pull the release pull line 67 through the anti-slip protrusion column 66, and then the pull line 6 is released. 7 pulls the clamping piston 57, and then the clamping piston 57 is pulled out from the inside of the socket limit groove 59 with the inclined clamping joint 58, and then the anti-slip protrusion column 66 contacts the top surface of the inner cavity of the bending accommodating cavity 63, and then the force application plate 65 is operated to apply a pulling force to the arc filling plate 52 by operating the vertical pull rod 64, the anti-slip protrusion column 66, the positioning center column 62, and the positioning and fixing diagonal support 61. Then the arc filling plate 52 is pulled out from the inside of the gas stagnation groove 45 with the pre-treatment filter element 23 through the air-blocking tubular plug 53 and the externally threaded butt joint 54, and then the pre-treatment filter element 23 with the externally threaded butt joint 54 is pulled out. The threaded butt joint 54 is rotated relative to the air-sealing tubular plug 53 until the air-sealing tubular plug 53 and the externally threaded butt joint 54 are separated, and then a new pre-treatment filter element 23 is taken out, and then the externally threaded butt joint 54 is connected with the air-sealing tubular plug 53, and then the pre-treatment filter element 23 is inserted into the gas retardation groove 45, and then the air-sealing tubular plug 53 is inserted into the gas retardation groove 45, and then the arc filling plate 52 is inserted into the enlarged positioning groove 51, and then the inner wall of the enlarged positioning groove 51 applies a thrust to the inclined surface of the bevel clamping joint 58, and then the bevel clamping joint 58 is clamped to the inside of the column cavity 55. Then the inclined clamp joint 58 slides into the inside of the enlarged positioning groove 51 and aligns with the socket limit groove 59. Then the clamping piston 57 inserts the inclined clamp joint 58 into the socket limit groove 59 under the action of the elastic force of the clamping spring 56. After that, the arc filling plate 52 is confined in the inside of the enlarged positioning groove 51, and the replacement of the pre-treatment filter element 23 is completed. Then the power distribution control box 15 is manually controlled to rotate the blocking sealing cylinder 44 by an angle, and the next pre-treatment filter element 23 is replaced. Repeat this process until the replacement of the pre-treatment filter element 23 is completed.
