[0017] The present invention also proposes a method for using a multifunctional waste gas purification and environmental protection device, comprising the following steps:

[0018] Step 1: Start the servo motor. The motor shaft of the servo motor drives the fixed shaft, sleeve, limit ring, driving gear, positioning cylinder, swing blade, and notched gear to rotate synchronously. The driving gear engages to drive the first gear ring and the dust removal cylinder to rotate in the opposite direction.

[0019] Step 2: The limiting ring and a pair of pulleys form a limiting effect, driving the elliptical slider and the arc-shaped partition to slide back and forth along the elliptical sliding hole, and then driving the arc-shaped brush plate to slide back and forth along the bottom wall of the dust collector through the connecting plate;

[0020] Step 3: The notched portion of the notched gear forms a limiting effect with the second gear ring, and the meshing of the notched gear drives the second gear ring, the stepped ring, the polygonal clamping plate, and the purification cylinder to intermittently rotate in the opposite direction along the positioning ring, the second clamping ring, and the annular channel steel;

[0021] Step 4: Start the water pump. Under the action of the water pump, the atomized liquid flows along the L-shaped atomizing pipe and sprays the air inlet holes on the purification cylinder. Since the purification cylinder is in intermittent reverse rotation, the atomized water droplets are evenly distributed in several air inlet holes.

[0022] Step 5: The exhaust gas enters the dust collection cylinder through the left port of the hollow cylinder, and the exhaust gas is dusted through the dust collection holes of the dust collection cylinder. A large amount of dust and impurities are adsorbed on the inner wall of the dust collection cylinder, and the curved brush plate scrapes the wall to clean the dust and impurities so that the dust and impurities enter the dust collection hopper;

[0023] Step 6: The exhaust gas after dust removal enters the middle part of the hollow cylinder through the connecting air hole and undergoes atomization. The atomized exhaust gas enters the purification cylinder through the air inlet hole, and then passes through the activated carbon adsorption filler, microbial adsorption filler, and demisting purification filler for purification and filtration in sequence. The purified exhaust gas enters the annular channel steel through the exhaust hole and is discharged through the exhaust pipe.

[0024] Step 7: When several dust removal holes are clogged, start the air pump. Under the action of the air pump, high-pressure gas flows along the L-shaped backwash pipe and the gas nozzle to backwash the dust removal holes on the dust removal cylinder. Since the dust removal cylinder is rotating in the reverse direction, the high-pressure gas backwashes the several dust removal holes evenly.

[0025] Step 8: Open the fixed cover and take out the purification cartridge, then open the purification cover and regularly replace the activated carbon adsorption filler, microbial adsorption filler, and demisting purification filler in the purification cartridge.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. In the present invention, while the dust collector rotates in the opposite direction, the reciprocating mechanism is used to drive the arc-shaped brush plate to reciprocate along the bottom wall of the dust collector to clean the wall, so that the dust falls into the dust collecting hopper. Then, through the backwashing effect of the air pump, the high-pressure gas is used to evenly backwash the dust collection holes to avoid clogging, thereby effectively improving the dust removal effect of the exhaust gas.

[0028] 2. In the present invention, the purifier cartridge is in intermittent reverse rotation through the use of a limiting mechanism. Then, through the action of the water pump, the atomized water droplets are evenly distributed in the several air inlet holes, so that the purifier cartridge can fully atomize the exhaust gas before the purification operation, prolonging the contact time between the exhaust gas and the atomized liquid, thereby improving the effect of subsequent exhaust gas purification;

[0029] To sum up, the present invention solves the problem of poor dust removal and atomization effect of waste gas, and the overall structural design is compact, which not only enhances the dust removal effect of waste gas, but also effectively prolongs the contact time between waste gas and atomizing liquid, thereby improving the practicality of the waste gas purification and environmental protection equipment.

[0046] The atomized waste gas is purified and filtered in sequence through the activated carbon adsorption filler 33, the microbial adsorption filler 34, and the demisting purification filler 35, which not only improves the waste gas purification effect, but also facilitates the adsorption and removal of harmful gases therein.

[0047] In the specific implementation process, Figure 3 and Figure 5 As shown, the right side of the purification cylinder 31 is provided with a slidingly connected annular channel steel 13, and the right side of the top wall of the hollow cylinder 1 is provided with a vertically penetrating fixed exhaust pipe 14, and the bottom end of the exhaust pipe 14 is connected to the top wall of the annular channel steel 13; the purified exhaust gas enters the annular channel steel 13 through the exhaust hole and is then discharged through the exhaust pipe 14;

[0048] A detachable fixed cover plate 17 is provided in the right port of the hollow cylinder 1, a rectangular sliding hole is provided at the bottom back of the dust collecting hopper 11, a sliding push-pull baffle is inserted into the inside of the rectangular sliding hole, and a drain pipe is provided on the right side wall of the sewage collecting tank 12, and a drain valve is installed at the outer end of the drain pipe.

The driving gear 6 is located below the first gear ring 61, and the driving gear 6 is meshed with the first gear ring 61;

[0050] When the fixed shaft 51 rotates, the fixed shaft 51 drives the driving gear 6 to rotate synchronously, and the driving gear 6 engages and drives the first gear ring 61 and the dust removal cylinder 21 to rotate in the opposite direction;

The bottom surface of the L-shaped atomizing pipe is provided with a plurality of atomizing nozzles corresponding to the air inlet holes. A water pump 16 is installed in the middle of the top wall of the hollow cylinder 1. The drainage end of the water pump 16 is connected to the L-shaped atomizing pipe.

[0055] Under the action of the water pump 16, the atomized liquid sprays the air inlet holes on the purification cylinder 31 along the L-shaped atomizing pipe and the atomizing spray. Since the purification cylinder 31 is in intermittent reverse rotation, the atomized water droplets are evenly distributed in the several air inlet holes.

[0056] Embodiment 2: In embodiment 1, there is still the problem that the dust removal holes are easily clogged. Therefore, based on embodiment 1, this embodiment further includes:

[0057] In the specific implementation process, Figure 4 and Figure 10 As shown, a number of evenly arranged dust removal holes are opened on the inner annular surface of the dust removal cylinder 21. The dust removal holes are divided into three parts from the inside to the outside. The first part has a large conical hole diameter, the second part has a medium conical hole diameter, and the third part has a straight hole diameter.

[0058] A horizontally placed L-shaped backwash pipe is provided above the top wall of the dust removal cylinder 21. An air pump 15 is installed on the left side of the top wall of the hollow cylinder 1. The exhaust end of the air pump 15 is connected to the L-shaped backwash pipe. The bottom surface of the L-shaped backwash pipe is provided with a plurality of gas nozzles corresponding to the dust removal holes.

[0059] Under the action of the air pump 15, high-pressure gas backwashes the dust removal holes on the dust removal cylinder 21 along the L-shaped backwash pipe and the gas nozzle. Since the dust removal cylinder 21 is in reverse rotation, the high-pressure gas backwashes the multiple dust removal holes evenly to avoid blockage.

[0060] Embodiment 3: In embodiment 1, there is still the problem that the dust removal effect of the dust removal cylinder 21 is not good. Therefore, based on embodiment 1, this embodiment further includes:

[0061] In the specific implementation process, Figure 5 and Figure 7 As shown, the reciprocating mechanism includes an elliptical slider 23 and a limiting ring 53. An elliptical sliding hole is opened in the middle of the U-shaped cover 22. The elliptical sliding hole is inserted into the inside of the elliptical sliding hole and the elliptical slider 23 is slidably connected. The top of the elliptical slider 23 is fixed with a connecting plate 24. The right end of the connecting plate 24 is fixedly connected to the left end of the arc-shaped brush plate 25. The middle of the elliptical slider 23 is fixed with an arc-shaped partition 26. The arc-shaped partition 26 is slidably connected to the top wall of the U-shaped cover 22.

[0062] A pair of rotatably connected pulleys 54 are provided at both ends of the bottom of the elliptical slider 23. A concentrically fixed sleeve 52 is sleeved on the left end of the fixed shaft 51. A concentrically fixed and obliquely distributed limiting ring 53 is sleeved in the middle of the sleeve 52. The top of the limiting ring 53 is engaged between the pair of pulleys 54.

[0063] When the fixed shaft 51 rotates, the fixed shaft 51 drives the sleeve 52 and the limiting ring 53 to rotate synchronously. The limiting ring 53 and a pair of pulleys 54 form a limiting effect, driving the elliptical slider 23 and the arc-shaped partition 26 to slide back and forth along the elliptical sliding hole, and then drives the arc-shaped brush plate 25 to slide back and forth along the inner bottom wall of the dust removal cylinder 21 through the connecting plate 24. The arc-shaped brush plate 25 can clean the dust and impurities adsorbed on the inner wall of the dust removal cylinder 21 and make them fall into the dust collecting hopper 11.

[0064] Embodiment 4: In embodiment 1, there is still the problem that the purification effect of the purification cartridge 31 is not good. Therefore, based on embodiment 1, this embodiment further includes:

[0065] In the specific implementation process, Figure 8 and Figure 9 As shown, the limiting mechanism includes a second gear ring 64 and a notched gear 63. A positioning ring 4 is fixedly provided on the top of the right side wall of the dust collecting hopper 11. The positioning ring 4 and the hollow cylinder 1 are concentrically distributed. A step ring 41 is inserted into the positioning ring 4 for rotation. A polygonal groove is provided in the middle of the right side surface of the step ring 41. A magnetic suction cup 42 is fixed in the middle of the inner wall of the polygonal groove. A polygonal clamping plate 43 is fixed in the middle of the left side wall of the purification cylinder 31. A circular groove is provided in the middle of the left side wall of the polygonal clamping plate 43. The polygonal clamping plate 43 is snap-fitted into the polygonal groove, and the magnetic suction cup 42 is snap-fitted into the circular groove. The coordinated use of the polygonal clamping plate 43 and the magnetic suction cup 42 facilitates the disassembly and maintenance of the purification cylinder 31.

[0066] A concentrically fixed second gear ring 64 is sleeved on the right side of the outer ring surface of the step ring 41, and a concentrically fixed notched gear 63 is sleeved on the right end of the fixed shaft 51. The notched parts of the notched gear 63 are arranged in a circle, and the notched gear 63 is meshed with the second gear ring 64; when the fixed shaft 51 rotates, the fixed shaft 51 drives the notched gear 63 to rotate synchronously, and the notched part of the notched gear 63 forms a limiting effect with the second gear ring 64. The meshing of the notched gear 63 drives the second gear ring 64, the step ring 41, the polygonal clamping plate 43, and the purification cylinder 31 to intermittently rotate in the opposite direction along the positioning ring 4, the second clamping ring 3 and the annular channel steel 13, so that the atomized water droplets are evenly distributed in the air inlet.

[0067] Embodiment 5: Specifically, the working principle and operation method of the present invention are as follows:

[0068] Step 1: Start the servo motor 5. The motor shaft of the servo motor 5 drives the fixed shaft 51, sleeve 52, limit ring 53, driving gear 6, positioning cylinder, swing blade 62, and notched gear 63 to rotate synchronously. The driving gear 6 engages and drives the first gear ring 61 and the dust removal cylinder 21 to rotate in the opposite direction.

[0069] Step 2: The limiting ring 53 and the pair of pulleys 54 form a limiting effect, driving the elliptical slider 23 and the arc-shaped partition 26 to slide back and forth along the elliptical sliding hole, and then driving the arc-shaped brush plate 25 to slide back and forth along the inner bottom wall of the dust removal cylinder 21 through the connecting plate 24;

[0070] Step 3: The notched portion of the notched gear 63 forms a limiting effect with the second gear ring 64. The notched gear 63 engages to drive the second gear ring 64, the stepped ring 41, the polygonal clamping plate 43, and the purification cartridge 31 to intermittently rotate in the opposite direction along the positioning ring 4, the second clamping ring 3, and the annular channel steel 13.

[0071] Step 4: Start the water pump 16. Under the action of the water pump 16, the atomized liquid flows along the L-shaped atomizing pipe and sprays the air inlet holes on the purification cylinder 31. Since the purification cylinder 31 is in intermittent reverse rotation, the atomized water droplets are evenly distributed in the several air inlet holes.

[0072] Step 5: The exhaust gas enters the dust collecting cylinder 21 through the left port of the hollow cylinder 1. The exhaust gas is removed through the dust collecting holes of the dust collecting cylinder 21. A large amount of dust and impurities are adsorbed on the inner wall of the dust collecting cylinder 21. The curved brush plate 25 scrapes the wall to clean the dust and impurities so that the dust and impurities enter the dust collecting hopper 11.

[0073] Step 6: The exhaust gas after dust removal enters the middle part of the hollow cylinder 1 through the connecting air hole and undergoes atomization. The atomized exhaust gas enters the purification cylinder 31 through the air inlet hole, and then passes through the activated carbon adsorption filler 33, the microbial adsorption filler 34, and the demisting purification filler 35 for purification and filtration. The purified exhaust gas enters the annular channel steel 13 through the exhaust hole and is discharged through the exhaust pipe 14.

[0074] Step 7: When several dust removal holes are clogged, start the air pump 15. Under the action of the air pump 15, high-pressure gas flows along the L-shaped backwash pipe and the gas nozzle to backwash the dust removal holes on the dust removal cylinder 21. Since the dust removal cylinder 21 is in reverse rotation, the high-pressure gas backwashes the several dust removal holes evenly.

[0075] Step eight, open the fixed cover 17, take out the purification cartridge 31, then open the purification cover 36, and regularly replace the activated carbon adsorption filler 33, microbial adsorption filler 34, and demisting purification filler 35 in the purification cartridge 31.

[0076] The present invention solves the problem of poor dust removal and atomization effects of waste gas, and the overall structural design is compact, which not only enhances the dust removal effect of waste gas, but also effectively prolongs the contact time between waste gas and atomizing liquid, thereby improving the practicability of the waste gas purification and environmental protection equipment.

[0077] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.

6. A method for using a multifunctional waste gas purification and environmental protection device according to claim 5, characterized in that: The following steps are involved: Step 1: Start the servo motor. The motor shaft of the servo motor drives the fixed shaft, sleeve, limit ring, driving gear, positioning cylinder, swing blade, and notched gear to rotate synchronously. The driving gear engages to drive the first gear ring and the dust removal cylinder to rotate in the opposite direction. Step 2: The limiting ring and a pair of pulleys form a limiting effect, driving the elliptical slider and the arc-shaped partition to slide back and forth along the elliptical sliding hole, and then driving the arc-shaped brush plate to slide back and forth along the bottom wall of the dust collector through the connecting plate; Step 3: The notched portion of the notched gear forms a limiting effect with the second gear ring, and the meshing of the notched gear drives the second gear ring, the stepped ring, the polygonal clamping plate, and the purification cylinder to intermittently rotate in the opposite direction along the positioning ring, the second clamping ring, and the annular channel steel; Step 4: Start the water pump. Under the action of the water pump, the atomized liquid flows along the L-shaped atomizing pipe and sprays the air inlet holes on the purification cylinder. Since the purification cylinder is in intermittent reverse rotation, the atomized water droplets are evenly distributed in several air inlet holes. Step 5: The exhaust gas enters the dust collection cylinder through the left port of the hollow cylinder, and the exhaust gas is dusted through the dust collection holes of the dust collection cylinder. A large amount of dust and impurities are adsorbed on the inner wall of the dust collection cylinder, and the curved brush plate scrapes the wall to clean the dust and impurities so that the dust and impurities enter the dust collection hopper; Step 6: The exhaust gas after dust removal enters the middle part of the hollow cylinder through the connecting air hole and undergoes atomization. The atomized exhaust gas enters the purification cylinder through the air inlet hole, and then passes through the activated carbon adsorption filler, microbial adsorption filler, and demisting purification filler for purification and filtration in sequence. The purified exhaust gas enters the annular channel steel through the exhaust hole and is discharged through the exhaust pipe. Step 7: When several dust removal holes are clogged, start the air pump. Under the action of the air pump, high-pressure gas flows along the L-shaped backwash pipe and the gas nozzle to backwash the dust removal holes on the dust removal cylinder. Since the dust removal cylinder is rotating in the reverse direction, the high-pressure gas backwashes the several dust removal holes evenly. Step 8: Open the fixed cover and take out the purification cartridge, then open the purification cover and regularly replace the activated carbon adsorption filler, microbial adsorption filler, and demisting purification filler in the purification cartridge.
