[0025] Please see Figure 3-5The filter mechanism 3 includes an outer disk 31, with a top filter disk 33 movably connected to the top of the outer disk 31 and a bottom filter disk 32 movably connected to the bottom of the outer disk 31. The outer wall of the outer disk 31 is fixedly connected to the inner wall of the filter housing 2. Vibration component connecting blocks 34 are fixedly connected to both sides of the bottom of the outer disk 31. U-shaped frames 35 are fixedly connected to the inner sides of the two vibration component connecting blocks 34. Rotating rods 36 are rotatably connected to the left and right sides of the inner sides of the two U-shaped frames 35. Push-pull rods 37 are rotatably connected to the bottom of the inner sides of the two sets of rotating rods 36. Push-pull blocks 313 are rotatably connected to the top of the two push-pull rods 37. The tops of the two push-pull blocks 313 are fixedly connected to both sides of the bottom of the bottom filter disk 32. U-shaped frames 35 are fixedly connected to the inner sides of the two vibration component connecting blocks 34. Rotating rods 36 are rotatably connected to the left and right sides of the inner sides of the two U-shaped frames 35. Push-pull rods 37 are rotatably connected to the bottom of the inner side. Push-pull blocks 313 are rotatably connected to the top of the two push-pull rods 37. The tops of the two push-pull blocks 313 are fixedly connected to the two sides of the bottom of the bottom filter plate 32. Push-pull blocks 313 are fixedly connected to the inner wall of the outer plate 31 in a ring array. Z-shaped connecting rods 314 are fixedly connected to the top and bottom of the inner side of the multiple push-pull blocks 313. Columnar push-pull rods 316 are slidably connected to the inner walls of the multiple sets of Z-shaped connecting rods 314. The tops of the multiple columnar push-pull rods 316 are fixedly connected to the multiple sides of the bottom of the top filter plate 33.

[0026] When it is necessary to filter dust and collect wastewater for recycling, the motor 38 is started. After the motor 38 starts, the transmission turntable 39 rotates. The rotation of the turntable 39 drives the second turntable 311 and the rotating rod 312 on its inner wall to rotate together via the track 310. The rotation of the rotating rod 312 drives the two sets of rotating rods 36 to rotate. The rotation of the two sets of rotating rods 36 drives the push-pull rod 37 to move back and forth, and pushes and pulls the bottom filter disc 32 back and forth via the push-pull block 313. The bottom filter disc 32 is located at the bottom of the inner wall of the outer disc 31. The arc-shaped pressure rod 317 is pushed and pulled back and forth, and after being subjected to force, the arc-shaped pressure rod 317 swings back and forth. In turn, the columnar push-pull rod 316 drives the top filter plate 33 to move back and forth on the top of the inner wall of the outer plate 31. During this process, the top filter plate 33 and the bottom filter plate 32 simultaneously squeeze and loosen the dust in the outer plate 31, which helps to improve the dust filtration effect and dust reduction efficiency. At the same time, the dust on the inner wall of the outer plate 31 is prevented from clogging the filter screen under the action of reciprocating compression and loosening, thus realizing the effective collection of sewage.

[0027] Please see Figure 6The atomizer 4 includes a motor mounting base 41. A lead screw motor 42 is fixedly connected to the inner wall of the motor mounting base 41. The output end of the lead screw motor 42 extends to the top of the motor mounting base 41 and is fixedly connected to a lead screw 43. A sliding plate 44 is movably connected to the top of the lead screw 43. A columnar connecting rod 45 is fixedly connected to the top center of the sliding plate 44. Second sliding plates 46 are fixedly connected to both sides of the outer wall of the columnar connecting rod 45. Slides 411 are arranged in a circular array at the bottom of both second sliding plates 46 and sliding plate 44. Through slots 412 are opened on the side of the outer wall of both second sliding plates 46 and sliding plate 44 that are aligned with the multiple slides 411. The inner walls of the multiple slides 411 opened on both second sliding plates 46 and sliding plate 44 are slidably connected to a receiving device. Multiple atomizing nozzles 414 are fixedly connected to the outer side of the expansion rod 413 and the multiple retraction expansion rod 413. The ends of the multiple atomizing nozzles 414 away from the expansion expansion rod 413 extend through the through groove 412 to the outer wall of the slide plate 44 and the two second slide plates 46. The bottom of the slide plate 44 is fixedly connected to the vertical connecting rod 47 in an annular array. The bottom of the multiple vertical connecting rods 47 is fixedly connected to the L-shaped support rod 48. The bottom of the multiple L-shaped support rod 48 is fixedly connected to the top of the filter housing 2 in an annular array. The outer wall of the screw 43 is threadedly connected to the drive shaft 49. The top of the drive shaft 49 is rotatably connected to the expansion and retraction rotating rod 410 in an annular array. The side of the multiple expansion and retraction rotating rod 410 away from the drive shaft 49 is rotatably connected to the bottom of the multiple expansion and retraction rods 413 respectively.

[0028] When atomization dust suppression is required for flue gas, the lead screw motor 42 is started. The output end of the lead screw motor 42 drives the lead screw 43 to rotate. The lead screw 43 drives the transmission shaft 49 to move up and down along the outer wall of the lead screw 43. The transmission shaft 49 drives the expansion and contraction rotating rod 410 to move. The expansion and contraction rotating rod 410 drives the expansion and contraction upright rod 413 to slide in the slide groove 411. The expansion and contraction upright rod 413 drives the atomizing nozzle 414 to move, thereby adjusting the spray range of the atomizing nozzle 414 as needed. When the transmission shaft 49 drives the expansion and contraction rod 414 to move, the atomizing nozzle 414 can be adjusted according to the requirements. When the expanding rotating rod 410 moves downward, the contracting rotating rod 410 drives the contracting rotating rod 413 to move closer to the inner wall of the slide groove 411. The contracting rotating rod 413 drives the atomizing nozzle 414 to move closer to the through groove 412, thereby reducing the spray range of the atomizing nozzle 414. When the drive shaft 49 drives the contracting rotating rod 410 to move upward, the contracting rotating rod 410 drives the contracting rotating rod 413 away from the inner wall of the slide groove 411. The contracting rotating rod 413 drives the atomizing nozzle 414 away from the through groove 412, thereby expanding the spray range of the atomizing nozzle 414.

[0029] Working principle: When it is necessary to filter dust and collect wastewater for dust suppression for recycling, the motor 38 is started. After the motor 38 starts, the drive turntable 39 rotates. The rotation of the turntable 39 drives the second turntable 311 and the rotating rod 312 on its inner wall to rotate together via the track 310. The rotation of the rotating rod 312 drives the two sets of rotating rods 36 to rotate. The rotation of the two sets of rotating rods 36 drives the push-pull rod 37 to move back and forth, and pushes and pulls the bottom filter plate 32 back and forth via the push-pull block 313. The bottom filter plate 32 moves back and forth at the bottom of the inner wall of the outer plate 31, and pushes and pulls the arc-shaped pressure rod 317 back and forth. The arc-shaped pressure rod 317 swings back and forth after being stressed, and then drives the top filter plate 33 to move back and forth at the top of the inner wall of the outer plate 31 via the columnar push-pull rod 316. During this process, the top filter plate 33 and the bottom filter plate 32 simultaneously perform back and forth squeezing and loosening operations on the dust in the outer plate 31, which helps to improve the dust filtration effect and dust suppression efficiency.

[0030] When atomization dust suppression is required for flue gas, the lead screw motor 42 is started. The output end of the lead screw motor 42 drives the lead screw 43 to rotate. The lead screw 43 drives the transmission shaft 49 to move up and down along the outer wall of the lead screw 43. The transmission shaft 49 drives the expansion and contraction rotating rod 410 to move. The expansion and contraction rotating rod 410 drives the expansion and contraction upright rod 413 to slide in the slide groove 411. The expansion and contraction upright rod 413 drives the atomizing nozzle 414 to move, thereby adjusting the spray range of the atomizing nozzle 414 as needed. When the transmission shaft 49 drives the expansion and contraction rod 414 to move, the atomizing nozzle 414 can be adjusted according to the requirements. When the expanding rotating rod 410 moves downward, the contracting rotating rod 410 drives the contracting rotating rod 413 to move closer to the inner wall of the slide groove 411. The contracting rotating rod 413 drives the atomizing nozzle 414 to move closer to the through groove 412, thereby reducing the spray range of the atomizing nozzle 414. When the drive shaft 49 drives the contracting rotating rod 410 to move upward, the contracting rotating rod 410 drives the contracting rotating rod 413 away from the inner wall of the slide groove 411. The contracting rotating rod 413 drives the atomizing nozzle 414 away from the through groove 412, thereby expanding the spray range of the atomizing nozzle 414.
