An air inlet 101 is provided on one side of the filter box 1. A filter screen 2 for filtering solid particle impurities in the exhaust gas is arranged in the filter box 1. A baffle 3 is slidingly arranged at the lower part of the side of the filter box 1 close to the air inlet 101. The baffle 3 slides up and down along the filter box 1. A spray tower 9 is installed on the side of the top of the filter box 1 away from the air inlet 101 by welding. An air outlet 901 is provided on the top of the spray tower 9. A spray assembly for purifying and absorbing exhaust gas is jointly arranged on the spray tower 9 and the filter box 1. It also includes a mounting frame 14, a motor 15, a toggle rod 16, a push seat 17, a guide frame 18, an extrusion plate 19 and a first elastic member 20. One side of the filter box 1 is bolted A mounting frame 14 is installed in a connection manner, and a motor 15 is installed on the mounting frame 14 by means of bolt connection. The output shaft of the motor 15 penetrates into the filter box 1, and the output shaft of the motor 15 is fixedly connected to a toggle rod 16 through a coupling. Push seats 17 are installed on both sides of the filter screen 2 away from the air inlet 101 by means of bolt connection. The toggle rod 16 cooperates with the push seat 17. Two guide frames 18 are installed on the inner wall of the filter box 1 close to the air inlet 101 by means of bolt connection. Extrusion plates 19 are slidably arranged on the two guide frames 18. The extrusion plates 19 slide laterally along the guide frames 18. A first elastic member 20 is wound around the guide frames 18. The two extrusion plates 19 are installed on the filter screen 2 by means of bolt connection.

[0031] See also Figure 2 and Figure 3As shown, the spray assembly includes a liquid storage tank 4 installed on the side of the filter box 1 away from the air inlet 101 by bolt connection, the liquid storage tank 4 is filled with a purification solution for absorbing harmful substances in the exhaust gas, the top of the liquid storage tank 4 is connected and communicated with a water inlet pipe 5, the top of the liquid storage tank 4 is installed with a water pump 6 by bolt connection, the side of the spray tower 9 is connected to the top of the liquid storage tank 4 and is communicated with a liquid infusion pipe 7, the liquid infusion pipe 7 is connected to the water pump 6, and one end of the liquid infusion pipe 7 located in the spray tower 9 is fixedly connected to a nozzle 8, a liquid storage tank 12 is provided in the filter box 1, and the liquid storage tank 12 is located directly below the nozzle 8. A water outlet valve 13 is connected and communicated with the lower side, and the water outlet valve 13 is connected to the liquid storage tank 12. A blocking net 10 is installed in the spray tower 9 by means of bolt connection. The blocking net 10 is located below the nozzle 8. The blocking net 10 is used to place hollow balls. The hollow balls can slow down the inflow of exhaust gas and the outflow of purified solution, so that the purified solution can fully absorb harmful substances in the exhaust gas. A storage net frame 11 is installed in the spray tower 9 by means of bolt connection. The storage net frame 11 is located above the nozzle 8. Fire core carbon is stored in the storage net frame 11. The fire core carbon can be used to dry the moisture in the gas that contacts the purified solution.

[0032] When it is necessary to absorb and filter the environmental exhaust gas, the exhaust gas is introduced into the filter box 1 through the air inlet 101, and the solid particles in the exhaust gas are adsorbed by the filter screen 2, so that the solid particles are filtered and removed, and then the exhaust gas enters the spray tower 9, and the purified solution in the liquid storage tank 4 is transported to the nozzle 8 through the infusion pipe 7 by starting the water pump 6, and the nozzle 8 sprays the purified solution into the spray tower 9 to absorb the harmful substances in the exhaust gas in the spray tower 9. The purified solution carries the harmful substances and falls into the liquid storage tank 12. The waste liquid in the liquid storage tank 12 can be discharged by controlling the water outlet valve 13 to open; the hollow balls placed on the barrier net 10 slow down the speed of the exhaust gas flowing upward, and at the same time slow down the purified solution passing through the barrier net 10 downward, so that the purified solution can fully remove the harmful substances in the exhaust gas. Material absorption, when the filtered air is continuously transported to the top of the spray tower 9, the fire core carbon in the storage frame 11 can dry the moisture contained in the gas, so that the discharged air is moderately reduced; when it is necessary to remove the solid particles adsorbed on the filter 2, the toggle rod 16 is driven to rotate by starting the motor 15, so that the toggle rod 16 pushes the push seat 17, so that the filter 2 slides along the guide frame 18 through the extrusion plate 19, and the first elastic member 20 is compressed and deformed by force. When the toggle rod 16 is out of contact with the push seat 17, the first elastic member 20 pushes the extrusion plate 19 to slide and reset, so that the filter 2 is reset, thereby causing the filter 2 to shake, and the solid particles attached to the filter 2 are shaken off to prevent the solid particles from clogging the filter 2.

[0033] Example 2: Based on Example 1, refer to Figure 4 and Figure 5As shown, it also includes a collecting frame 21 slidably arranged in the filter box 1, the collecting frame 21 is used to collect solid particle impurities shaken off the filter screen 2, a cover plate 22 is rotatably arranged on the collecting frame 21, and rotating disks 23 are rotatably arranged on both sides of the collecting frame 21. The rotating disk 23 and the collecting frame 21 are fixedly connected with a second elastic member 24 by welding, and a push rod 2301 is fixedly connected to the rotating disk 23 by welding, and protrusions 2201 are fixedly connected to both sides of the cover plate 22, and the protrusions 2201 cooperate with the push rod 2301.

[0034] When the solid particle impurities on the filter screen 2 are shaken off, the solid particle impurities fall into the collecting frame 21, and the collecting frame 21 is pulled out of the filter box 1 to slide, so that the baffle 3 gradually breaks away from the limit on the cover plate 22. At this time, the second elastic member 24 loses the force to twist and recover, so that the second elastic member 24 drives the rotating disk 23 to rotate and reset, and the rotating disk 23 pushes the protrusion 2201 through the push rod 2301 to make the cover plate 22 rotate and cover the top of the collecting frame 21 to prevent the dust and solid particle impurities in the collecting frame 21 from leaking out; after the collecting frame 21 is pushed into the filter box 1, the baffle 3 can push the cover plate 22 to rotate 180 degrees to unfold. At this time, the collecting frame 21 is directly below the filter screen 2, and the cover plate 22 pushes the push rod 2301 through the protrusion 2201 to make the rotating disk 23 rotate in the opposite direction. At this time, the second elastic member 24 is torsionally deformed by force.

[0035] See also Figure 4-Figure 7 As shown, it also includes a water storage tank 25 installed on both sides of the filter box 1 by bolt connection, the water storage tank 25 is connected to the filter box 1 and is communicated with a liquid guide tube 26, a piston rod 27 is horizontally slidably arranged in the liquid guide tube 26, and a shift block 28 is rotatably arranged at one end of the piston rod 27 located outside the liquid guide tube 26, and two upper and lower third elastic members 29 are fixedly connected between the shift block 28 and the piston rod 27 by welding, and convex plates 2801 are fixedly connected on both sides of the collection frame 21 by welding, and the shift block 28 cooperates with the convex plate 2801.

[0036] When a lot of dust and solid particles are collected in the collection frame 21, if the collection frame 21 is to be taken out, the water in the water storage tank 25 uses the communicating vessel principle to make the liquid level in the liquid guide tube 26 flush with the liquid level in the water storage tank 25. When the collection frame 21 is slid out, the collection frame 21 pulls the shifting blocks 28 on both sides through the convex plates 2801 on both sides, so that the shifting blocks 28 drive the piston rod 27 to slide and push the water in the liquid guide tube 26 into the collection frame 21, so that the water is mixed with the dust and solid particles in the collection frame 21 and agglomerated, so that the dust and impurities will not float when the collection frame 21 is slid out. When the rod 27 is pulled to the extreme position, as the collecting frame 21 is pulled out, the convex plate 2801 drives the shift block 28 to rotate, so that the third elastic member 29 is subjected to force and twisted and deformed. After the convex plate 2801 is separated from the shift block 28, the shift block 28 is rotated and restored by the third elastic member 29. When the collecting frame 21 is slid into the filter box 1, the shift block 28 is pushed by the convex plate 2801 to make the piston rod 27 slide into the liquid guide tube 26. When the piston rod 27 is at the limit, the convex plate 2801 drives the shift block 28 to rotate. When the convex plate 2801 passes over the shift block 28, the third elastic member 29 drives the shift block 28 to rotate and reset.

[0037] See also Figure 8 and Fig. 9 As shown, it also includes an air guide cabinet 30 fixedly connected to the spray tower 9 by welding. Both ends of the air guide cabinet 30 are connected to the spray tower 9. Two guide plates 31 are installed on the air guide cabinet 30 by welding. The two guide plates 31 are slidably provided with an air blocking plate 32. The air blocking plate 32 is slidably penetrated in the air guide cabinet 30. The infusion tube 7 penetrates the air guide cabinet 30. A spiral air guide plate 33 is fixedly connected to the air guide cabinet 30 by welding. The spiral air guide plate 33 is wound around the infusion tube 7.

[0038] When the waste gas carrying heat enters the spray tower 9, the hot gas enters the gas guide cabinet 30 and is transported upward through the spiral gas guide plate 33. At this time, the hot gas transfers the heat to the infusion pipe 7 to heat the purification solution in the infusion pipe 7, so that the purification solution can better absorb harmful impurities in the waste gas. The waste gas after heat transfer flows back to the spray tower 9 through the upper outlet of the gas guide cabinet 30. When the gas guide cabinet 30 needs to be closed, the air blocking plate 32 is pushed to slide along the guide plate 31 into the gas guide cabinet 30 to block the circulation of the gas guide cabinet 30. At this time, the purification solution flowing through the infusion pipe 7 cannot be heated.

[0039] See also Figure 1 and Figure 3 As shown, a sealing gasket 34 is sleeved on the toggle rod 16, and a screw cap 35 is threadedly arranged on the top of the water inlet pipe 5. The sealing gasket 34 is used to seal the gap between the toggle rod 16 and the filter box 1 to prevent the exhaust gas from overflowing; the screw cap 35 is used to prevent foreign matter from entering the liquid storage tank 4 through the water inlet pipe 5 to avoid contaminating the purified solution.
