[0027] In this embodiment, the water extraction pipe 54 extracts the purified liquid from the air box 4 through the water hole 58 and one end thereof, during which the filter cover 57 filters the impurities in the purified liquid. The extracted purified liquid enters the spray pipe 51 through the water supply pipe 53, and sprays and purifies the flowing flue gas through the spray hole 52, so that the impurities in the flue gas absorb the increased gravity and fall and separate, thereby filtering the impurities, and dehumidifies the air after spray purification through the filter cotton column 12 to avoid waste of purified liquid.

[0028] Embodiment 3: Based on Embodiment 2, refer to the attached Figure 3 , Attachment Figure 4 ; A pumping unit 55 is provided inside the water pumping pipe 54. The pumping unit 55 includes a piston 551 with a check valve. The piston 551 can gradually discharge the air below the water pumping pipe 54 through the action of the check valve, so as to extract the purified liquid by utilizing the negative pressure. The outer surface of the piston 551 is slidably connected to the inside of the water pumping pipe 54. The outer surface of the piston 551 is fixedly connected to a slide rod 552. The cross-section of the end of the slide rod 552 is rectangular to improve the stability of sliding. One end of the slide rod 552 is fixedly connected to a pressure plate 553.

One end of the through pipes 555 on both sides is connected with the inside of the water pumping pipe 54. The outer surface of the slide bar 552 is sleeved with two magnetic rings 556 that act by magnetic repulsion. The magnetic rings 556 can act as damping through the repulsion to facilitate the reset of the pressure plate 553, and the magnetic rings 556 located on the support plate 554 can be replaced by electromagnets. The outer surfaces of the two magnetic rings 556 are respectively fixedly connected to the outer surfaces of the pressure plate 553 and the support plate 554.

The two ends of the compression spring 557 are respectively fixedly connected to the outer surfaces of the pressure plate 553 and the support plate 554.

[0029] In this embodiment, the air inside the air pipe 2 enters the water extraction pipe 54 through the connecting pipe 56 to press down the pressure plate 553, so that the slide rod 552 drives the piston 551 to follow the movement, thereby compressing the air at the bottom of the water extraction pipe 54 to the top of the inside and discharging it through the lower through pipe 555. At the same time, the pressure plate 553 slides down so that the purified gas is discharged through the upper through pipe 555. At the same time, the compression spring 557 rebounds and the repulsive force of the two magnetic rings 556 causes the pressure plate 553 to drive the piston 551 to rise and reset. This process is repeated to exhaust the air inside the water extraction pipe 54 and extract the purified liquid inside the air box 4 by the negative pressure.

A bolt 38 is threadedly connected to the body of the square tube 31, and one end of the bolt 38 abuts against the outer surface of the rectangular bar 36.

[0031] In this embodiment, according to the position of the weld, the rectangular bar 36 is pulled to slide inside the square tube 31 so that the weld is on the movement path of the tamping column 37. The rectangular bar 36 is then clamped and fixed by the bolt 38. The square tube 31 rotates around the support rod 34 as a whole and compresses the torsion spring 35. The torsion spring 35 rebounds and drives the tamping column 37 to reverse and reset through the rectangular bar 36. The tamping column 37 knocks on the weld, causing the welding slag to fall off automatically.

The outer surface of the abutment bar 324 on one side is rotatably connected to the inside of the air pipe 2, and the outer surface of the abutment bar 324 on one side abuts the outer surface of the filter screen 11 on the other side. The abutment bars 324 on the other side are equidistantly arranged along the axial direction of the cross bar 321, and are arranged at equal angles along the radial direction of the cross bar 321. The outer surface of the abutment bar 324 on the other side abuts the outer surface of the square tube 31. One end of the cross bar 321 is rotatably connected with a support bar 325, which can improve the force and balance of the cross bar 321, and the outer surface of the support bar 325 is fixedly connected to the top of the roller frame of the conveyor 1.

[0033] In this embodiment, the rotating rod 7 drives the cross bar 321 to rotate synchronously by engaging the rotating gear 322 and the transmission gear 323, and the cross bar 321 drives the two side bars 324 to rotate synchronously, and one side bar 324 reciprocates to push a filter screen 11 to slide, so that it squeezes the filter cotton column 12, so that the purified liquid water vapor adsorbed in the filter cotton column 12 condenses and separates, and the separated purified liquid flows back to the inside of the air box 4 through the lowest slide groove 13, and the other side bar 324 sequentially abuts the square tube 31, so that the tamping column 37 knocks on the weld.
