Description

Technical Field

[0001] The invention belongs to the technical field of electrostatic dust removal, and in particular relates to waste gas emission treatment equipment. Background Art

[0002] With the requirements of environmental protection, the treatment of waste gas generated in industrial production has become an important issue. As a mature and widely used technology, electrostatic precipitator occupies an important position in the field of waste gas purification. Its basic principle is to use a high-voltage electric field to charge the particles in the exhaust gas, and then these charged particles are attracted and deposited on the dust collecting plate with the opposite charge. During the operation of the electrostatic precipitator, a large amount of dust will gradually accumulate on the dust collecting plate. If it is not cleaned in time, it will affect the dust removal efficiency of the equipment and even cause system failure. Therefore, cleaning technology has become one of the key links to ensure the normal operation of the electrostatic precipitator. One of the most commonly used cleaning methods at present is the knocking and vibration cleaning method, that is, by regularly knocking or vibrating the dust collecting plate, the dust attached to its surface falls off and is collected.

[0003] In the prior art (publication number CN118218134B, patent name is a patent application for a vibrating hammer for an electrostatic precipitator filter plate and a hammering method thereof), the dust collecting plate is cleaned by hammering when a hammering rod is driven by a vibrating motor to knock on the striking plate. In the process of implementing this technical solution, it is found that there are at least the following problems in the prior art.

[0004] In the above patent, after collecting dust, the dust collecting plate inside the electrostatic precipitator will remove the dust on its surface through knocking and vibration. However, there is a problem with this knocking and vibration method of removing dust.

Of course, they are only examples, and the purpose is not to limit the embodiments of the present invention. In addition, the embodiments of the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0047] like Figure 1-Figure 2 As shown, an exhaust gas treatment device of the present invention includes an electrostatic precipitator 1 for treating exhaust gas, and an air inlet 12 is fixed on one side of the outer surface of the electrostatic precipitator 1. When the exhaust gas needs to be discharged, the exhaust gas can be guided to the inside of the electrostatic precipitator 1 through the air inlet 12, and then the exhaust gas is treated. A support frame 14 is also fixed below the electrostatic precipitator 1.

[0048] like Figure 2-Figure 8 As shown, a top plate 16 is fixed on the top of the inner cavity of the electrostatic precipitator 1, and an electrode 15 is extended from the surface of the top plate 16 to the inside of the electrostatic precipitator 1, and the electrodes 15 are equidistantly distributed on the surface of the top plate 16. At the same time, dust collecting plates 3 are respectively arranged on both sides of the electrode 15, and two parallel and opposite dust collecting plate 3 areas are opposite to the air inlet 12, and the area is a high-voltage electric field area 13. When the exhaust gas passes through the high-voltage electric field area 13 through the air inlet 12, the dust particles in the exhaust gas can be given an electric charge, and then can be adsorbed by the surface of the dust collecting plate 3. One end of the dust collecting plate 3 is fixedly connected to the surface of the top plate 16. A fence 17 is also arranged relatively below the top plate 16.

[0049] Rotating frames 34 are fixed at the upper and lower ends of the dust collecting plate 3, and reciprocating screws 341 and rotating shafts 342 are respectively provided on both sides of the rotating frame 34. One end of the reciprocating screw 341 and the rotating shaft 342 extends to the top of the top plate 16. Sprockets 345 are respectively fixed on the top of the reciprocating screw 341 and the rotating shaft 342 above the top plate 16. At the same time, a guide column 161 is also provided between two adjacent sprockets 345, and one end of the guide column 161 is fixed to the surface of the top plate 16. The outer peripheral surface of the sprocket 345 is driven by the chain 4, and a motor 41 is fixed on one side above the top plate 16, and a sprocket 42 provided at the power output end of the motor 41 drives the chain 4 to rotate. Therefore, when the motor 41 is running, the motor 41 can rotate the sprocket wheel 2 42 disposed above, and as the sprocket wheel 2 42 rotates, the sprocket wheel 1 345 is driven to rotate through the chain 4.

[0050] like Figure 7-Figure 11 As shown, a telescopic cylinder 35 is fixed on one side of the outer surface of the dust collecting plate 3, and the hole at one end of the telescopic cylinder 35 penetrates the surface of the dust collecting plate 3. At the same time, the surface of the dust collecting plate 3 close to the electrode 15 is covered with an expansion film 33, and the expansion film 33 is made of a certain conductive material to form a film, which can then allow electric charges to pass through. A telescopic piston 351 is coaxially arranged inside the telescopic cylinder 35, and a push rod 352 is hinged at the end of the piston 351. A rotating shaft frame 31 is also fixed on both sides of the surface of the dust collecting plate 3, and a rotatable crankshaft 32 is arranged between the two rotating shaft frames 31, and the middle part of the outer surface of the crankshaft 32 is hinged with the end of the push rod 352. Therefore, when the crankshaft 32 rotates, the piston 351 can be continuously telescopically displaced inside the telescopic cylinder 35 through the push rod 352.

[0051] A gear 321 is fixed at one end of the crankshaft 32, and the gear 321 is meshed with the crown gear 344 evenly distributed on the outer circumference of the rotating shaft 342. Therefore, when the exhaust gas enters the high-voltage electric field area 13 through the air inlet 12, it is ionized by the electrode 15, and then the dust in the exhaust gas is adsorbed and collected by the dust collecting plate 3. When the dust on the surface of the dust collecting plate 3 needs to be cleaned, the motor 41 located above the top plate 16 is operated. As the motor 41 is operated, the sprocket 2 42 provided thereon drives the chain 4. After the chain 4 rotates, the sprocket 345 can rotate. After the sprocket 345 rotates, the rotating shaft 342 fixed below can rotate together, and as the rotating shaft 34 After the rotation, the gear 1 321 meshingly connected on one side can be driven by the crown gear 344, and then the crankshaft 32 connected on one side of the gear 1 321 rotates. When the crankshaft 32 rotates, the piston 1 351 can be continuously telescopically displaced inside the telescopic cylinder 35 through the push rod 1 352. As the piston 1 351 is telescopically displaced, the expansion film 33 covered on the surface of the dust collecting plate 3 can be continuously expanded and contracted, and then the dust adsorbed on the surface of the expansion film 33 can fall off under the expansion and contraction, and then discharged from the discharge port 11.

[0052] like Figure 8-Figure 11 As shown, a bracket 18 is relatively arranged below the dust collecting plate 3, and the two ends of the bracket 18 are connected to the inner wall of the fence 17. A gear 2 343 is fixed at the end of the rotating shaft 1 342, and the gear 2 343 can drive the toothed ring 183 arranged above the bracket 18, and the toothed ring 183 is meshed with the gear 2 343, and the gear frame 1 181 arranged on both sides above the bracket 18 is connected with the toothed ring 183, so that the toothed ring 183 can rotate, and the gear frame 2 182 is relatively arranged below the toothed ring 183, and the two ends of the gear frame 2 182 are fixedly connected to the inner wall of the bracket 18.

[0053] At the same time, a gear 3 5 is meshed on one side of the inner wall of the gear ring 183, and a gear 4 51 is also meshed on one side of the gear 3 5, and the diameter of the gear 4 51 is smaller than that of the gear 3 5. At the same time, a magnetic sleeve 52 extends downward from the center of the bottom surface of the gear 4 51, and a rotating shaft 2 53 that can rotate is extended in the direction of the magnetic sleeve 52 at the bottom surface of the gear frame 2 182, and the top of the rotating shaft 2 53 is sleeved by the magnetic sleeve 52, so when the magnetic sleeve 52 rotates, the rotating shaft 2 53 can be soft-started. A fan blade 531 is also fixed to the outer circumference of the rotating shaft 2 53. Therefore, when the dust on the surface of the dust collecting plate 3 needs to be processed, at this time, under the rotation of the rotating shaft 1 342, the expansion film 33 covering the surface of the dust collecting plate 3 can continuously expand and contract, so that the dust can fall off, and as the rotating shaft 1 342 rotates, the gear 2 343 fixedly connected to its bottom can drive the gear ring 183 engaged on one side, and after the gear ring 183 rotates, it drives the gear 3 5 and the gear 4 51 in turn, and then the magnetic sleeve 52 provided under the gear 4 51 can drive the fan blade 531 to rotate through magnetism, and as the fan blade 531 rotates, the airflow can be accelerated, and then the dust in the area between the two dust collecting plates 3 can be moved toward the discharge port 11 for collection.

[0054] like Figure 12-Figure 15 As shown, an air cylinder 2 is arranged opposite to the upper surface of the top plate 16, and the interior of the air cylinder 2 is arranged in a hollow structure. A pressure relief valve 21 is fixed on the upper side of the air cylinder 2, and an exhaust pipe 25 is also arranged opposite to the bottom surface of the air cylinder 2. The bottom opening of the exhaust pipe 25 is connected to the exhaust port 162 that penetrates the surface of the top plate 16, and the opening of the exhaust port 162 is located on one side of the surface of the dust collecting plate 3. At the same time, connecting pipes 22 are extended in the direction of the exhaust pipe 25 on both sides of the outer surface of the air cylinder 2. The exhaust pipe 25 can be connected with the air cylinder 2 through the connecting pipe 22, and a solenoid valve 221 is also arranged on the connecting pipe 22, and the airflow can be opened and closed by the solenoid valve 221.

[0055] A pressurized tube 23 is fixed on one side of the outer surface of the gas storage cylinder 2, and the pressurized tube 23 is connected to the inside of the gas storage cylinder 2. At the same time, a piston 24 is coaxially arranged inside the pressurized tube 23, and a push rod 2 346 is hinged at one end of the piston 24, and the other end of the push rod 2 346 is connected to one side of the upper surface of the sprocket 1 345. Therefore, after the sprocket 1 345 rotates, the piston 24 can be continuously retracted and reciprocated along the inside of the pressurized tube 23 through the push rod 2 346. A one-way valve 1 231 is fixed on one side of the upper part of the outer peripheral surface of the pressurized tube 23, and a one-way valve 2 232 that can be flipped is also arranged at the air inlet opening of the pressurized tube 23. Therefore, when the rotating shaft 1 342 rotates to clean the dust on the surface of the dust collecting plate 3, the rotation of the sprocket 1 345 causes the push rod 2 346 to continuously push the piston 24 to move inside the pressurized tube 23. Then the gas inside the pressurized pipe 23 can enter the interior of the gas cylinder 2. After the internal pressure of the gas cylinder 2 reaches a certain level, the gas inside the gas cylinder 2 can be quickly and briefly discharged from the exhaust pipe 25 through the opening and closing of the solenoid valve 221, and blown to the surface of the dust collecting plate 3, thereby achieving the effect of dust removal and cleaning.

[0056] like Figure 16-Figure 19 As shown, when the dust on the surface of the dust collecting plate 3 needs to be cleaned, some of the dust on the surface is not easy to fall off, so it is necessary to clean part of the dust on the surface. The blowing box 6 is sleeved on the two opposite reciprocating screws 341, and the reciprocating screw holes 61 on both sides of the surface of the blowing box 6 are penetrated by the reciprocating screw 341. At the same time, one end of the insert 611 provided on the inner ring wall of the reciprocating screw hole 61 extends into the path of the surface of the reciprocating screw 341. As the reciprocating screw 341 rotates, it passes through its insert 611, so that the blowing box 6 can continuously reciprocate up and down.

[0057] At the same time, the interior of the blowing box 6 is arranged in a hollow structure, and an air pump 65 is fixed inside the blowing box 6. A filter 64 for filtering gas is fixed on one side of the surface of the blowing box 6, and the air inlet end of the air pump 65 is connected to the filter 64 through an air inlet pipe 66. At the same time, an air duct 62 is extended in the direction of the expansion membrane 33 on one side of the outer surface of the blowing box 6, and a blowing hole 63 is provided on the surface of the air duct 62 opposite to the expansion membrane 33. Therefore, when the chain 4 drives the sprocket wheel 1 345 to rotate, the reciprocating screw rod 341 provided under the sprocket wheel 1 345 rotates. As the reciprocating screw rod 341 rotates, the blowing box 6 moves downward immediately. When the blowing box 6 moves, the air pump 65 inside the blowing box 6 is operated, and the gas generated by the operation of the air pump 65 can be discharged through the exhaust end, and blown to the surface of the expanding and contracting expansion membrane 33 through the blowing hole 63, which can further improve the removal of dust on the surface of the dust collecting plate 3.

[0058] Working principle of an exhaust gas treatment device: When the exhaust gas enters the high-voltage electric field area 13 through the air inlet 12, the exhaust gas will be ionized under the action of the electrode 15. Then, the dust particles carried in the exhaust gas will be attracted by the dust collecting plate 3 and adhere to its surface. When it is necessary to remove the accumulation on the dust collecting plate 3, the motor 41 located above the top plate 16 starts to work. After the motor 41 is started, it will drive the sprocket 2 42 connected to it to rotate, and then drive the chain 4. The movement of the chain 4 in turn promotes the rotation of the sprocket 1 345, which further causes the rotation of the rotating shaft 1 342 fixedly connected thereto. The rotation of the rotating shaft 1 342 is transmitted to the gear 1 321 meshing with it through the crown gear 344, so that the gear 1 321 also starts to rotate and drives the crankshaft 32 connected thereto to rotate. As the crankshaft 32 rotates, it pushes the piston 1 351 to repeatedly telescope and move in the telescopic cylinder 35 through the push rod 1 352. The expansion and contraction movement of the piston 351 causes the expansion film 33 covering the surface of the dust collecting plate 3 to expand and contract repeatedly. This process helps to shake off the dust adsorbed on the surface of the expansion film 33, and finally discharge and collect it through the discharge port 11;

[0059] The rotation of the rotating shaft 1 342 not only causes the expansion film 33 covering the surface of the dust collecting plate 3 to expand and contract repeatedly, thereby helping the dust to fall off, but also the gear 2 343 fixedly connected to the bottom of the rotating shaft 1 342 will rotate accordingly. The rotation of the gear 2 343 will drive the gear ring 183 meshing with one side thereof to rotate. The rotation of the gear ring 183 in turn drives the rotation of gear 3 5 and gear 4 51. A magnetic sleeve 52 is provided under the gear 4 51, which drives the fan blade 531 to rotate through the action of magnetic force. As the fan blade 531 rotates, the air flow velocity is increased, which can promote the dust located between the two dust collecting plates 3 to move toward the discharge port 11 for centralized collection and treatment;

[0060] When the rotating shaft 1 342 rotates to clean the dust on the surface of the dust collecting plate 3, the rotation of the sprocket 1 345 will drive the push rod 2 346 to move, causing it to continuously push the piston 2 24 to move back and forth in the pressurizing tube 23. As the piston 2 24 reciprocates in the pressurizing tube 23, the gas in the pressurizing tube 23 is compressed and sent into the gas cylinder 2. When the pressure inside the gas cylinder 2 accumulates to a certain level, by controlling the opening and closing of the solenoid valve 221, the high-pressure gas in the gas cylinder 2 can be discharged from the exhaust pipe 25 in the form of short and strong pulses, and blown directly onto the surface of the dust collecting plate 3. This pulse jet of high-pressure gas helps to remove dust remaining on the surface of the dust collecting plate 3, thereby achieving a more thorough cleaning effect;

[0061] When the chain 4 drives the sprocket wheel 345 to rotate, the reciprocating screw 341 arranged below the sprocket wheel 345 also rotates. As the reciprocating screw 341 rotates, the blow box 6 connected thereto moves downward. During the movement of the blow box 6, the air pump 65 inside it starts to operate. The airflow generated by the operation of the air pump 65 will be discharged from the exhaust end and blown to the expanding membrane 33 that is expanding and contracting through the blowing holes 63 on the blow box 6. Such airflow assistance can effectively enhance the removal effect of dust on the surface of the dust collecting plate 3, ensuring that the dust can be removed more thoroughly and moved to the discharge port 11 for processing.

[0062] It should be noted that the specific models and specifications of the electrode 15, solenoid valve 221, motor 41 and air pump 65 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.
