Description

Technical Field

[0001] The invention relates to the technical field of formaldehyde oxidation, in particular to a formaldehyde oxidation reactor. Background Art

[0002] Formaldehyde is a naturally occurring organic compound, a colorless irritating gas that is irritating to the eyes and nose and is listed as a "known human carcinogen". Formaldehyde has a wide range of uses and is a popular chemical product with a simple production process and sufficient raw material supply. Some industrial waste gases contain formaldehyde and dust. If the industrial waste gases are directly discharged into the air, it will pollute the surrounding environment.

[0003] The existing formaldehyde oxidation reactor passes waste gas containing formaldehyde into a potassium permanganate solution to purify the formaldehyde. However, during purification, an exhaust pipe is generally inserted into the bottom of the potassium permanganate solution. When the waste gas containing formaldehyde contacts the potassium permanganate solution, some large bubbles are generated, resulting in insufficient reaction between the formaldehyde and the potassium permanganate solution, thereby resulting in an insufficient purification effect on the formaldehyde.

[0004] Therefore, a formaldehyde oxidation reactor is proposed. Summary of the invention

[0005] The object of the present invention is to provide a formaldehyde oxidation reactor. By setting a dividing mechanism, the existing way of air intake through a pipe is changed, the industrial waste gas is divided into multiple parts, and the industrial waste gas is contacted with a potassium permanganate solution from various places at the bottom, so that the industrial waste gas is in contact with the potassium permanganate solution more fully, which is beneficial to purify the formaldehyde and improves the efficiency of formaldehyde purification. By setting a crushing mechanism, large bubbles are crushed, and the contact area between the gas and the potassium permanganate solution is increased, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a formaldehyde oxidation reactor, comprising a reactor body, a filter chamber is fixedly installed at the lower left part of the reactor body, an air inlet pipe is movably installed at the left side of the filter chamber, and the reactor body, the filter chamber and the air inlet pipe are interconnected, a splitting mechanism and a crushing mechanism are movably arranged in sequence from bottom to top inside the reactor body, and the splitting mechanism and the crushing mechanism cooperate with each other, an anti-blocking mechanism cooperating with the splitting mechanism is movably arranged at a position near the lower end of the left side of the reactor body, and a processing mechanism and a scraping mechanism are movably arranged in sequence from top to bottom inside the filter chamber, and the processing mechanism cooperates with the anti-blocking mechanism;

[0007] The dividing mechanism includes a No. 1 support plate, a No. 2 support plate, a support column, a large air hole and a baffle. The interior of the reactor body is fixedly inserted with a No. 1 support plate and a No. 2 support plate from top to bottom near the lower end, and the interior of the reactor body is located above the No. 1 support plate and is filled with a potassium permanganate solution. The support column slides through the No. 1 support plate and the No. 2 support plate, and the number of the support columns is multiple groups. The large air hole is opened on the surface of the No. 1 support plate at a position corresponding to the support column, and the large air hole cooperates with the support column. The baffle is fixedly installed on the upper part of the support column, and the baffle cooperates with the large air hole. The No. 1 spring is movably sleeved on the outer surface of the support rod near the lower end, and the No. 1 spring is fixedly connected to the lower part of the No. 2 support plate.

[0008] The crushing mechanism includes a mounting plate, small air holes, a threaded rod, a threaded block and a mounting block. The mounting plate is fixedly inserted in the middle position inside the reactor body. The small air holes are opened on the surface of the mounting plate, and the number of small air holes is multiple. The threaded rod is fixedly connected to the outer surface of the upper end of the baffle, and the threaded rod is slidably connected to the mounting plate. The threaded block is threadedly sleeved on the outer surface of the threaded rod, and the threaded block is rotatably connected to the lower part of the mounting plate. The mounting block is fixedly connected to the outer surface of the threaded block, and the number of mounting blocks is multiple.

[0009] Generally, the pipe for discharging industrial waste gas is inserted into the interior of the reactor body, so that the industrial waste gas is in contact with the potassium permanganate solution, thereby purifying the formaldehyde in the industrial waste gas. However, in this purification method, the contact area between the gas and the potassium permanganate solution is relatively small, so that the reaction is not sufficient, and thus there is a disadvantage that the formaldehyde purification is not thorough enough. Since the No. 1 support plate and the No. 2 support plate are fixedly inserted into the interior of the reactor body, the potassium permanganate liquid is filled in the interior of the reactor body above the No. 1 support plate, and then the industrial waste gas is discharged into the interior of the filter chamber through the air inlet pipe. The industrial waste gas reaches the interior of the reactor body through the filter chamber and is located between the No. 1 support plate and the No. 2 support plate. If the industrial waste gas is continuously discharged, the No. 1 support plate will increase. When the air pressure between the support plate and the No. 2 support plate reaches a certain value, it will push the baffle plate, enter the upper end of the No. 1 support plate through the air hole, and come into contact with the potassium permanganate solution. When the air pressure between the No. 1 support plate and the No. 2 support plate decreases, with the cooperation of the support column and the No. 1 spring, and at the same time, under the action of water pressure, the baffle plate is reset to block the air hole again, so that the industrial waste gas between the No. 1 support plate and the No. 2 support plate cannot reach the top of the No. 1 support plate. It should be noted that the pressure of a standard atmospheric pressure is about the same as the pressure at a depth of ten meters. Therefore, when exhausting upward, the potassium permanganate solution inside the reactor body will not flow to the bottom of the No. 1 support plate through the air hole. By setting a dividing mechanism , which changes the existing way of air intake through one pipe, divides the industrial waste gas into multiple parts, and contacts the potassium permanganate solution from various places at the bottom, so that the industrial waste gas contacts the potassium permanganate solution more fully, which is beneficial to purify the formaldehyde and improves the efficiency of formaldehyde purification. When the industrial waste gas contacts the potassium permanganate solution, bubbles will be generated. When the formaldehyde is inside the bubbles, it cannot contact the potassium permanganate solution fully. Since the mounting plate is fixedly inserted inside the reactor body, when the bubbles rise to the position of the mounting plate, the bubbles can only continue to float up through the small pores. Since the diameter of the small pores is relatively small, the bubbles can be divided. With the cooperation of the dividing mechanism, the baffle moves up and down. During the process, the threaded rod is driven to move up and down. Since the threaded rod is threadedly connected to the threaded block, the threaded rod drives the threaded block to rotate during the up and down movement, thereby driving the mounting block to rotate. The mounting block can break the bubbles that remain under the mounting plate and drive these bubbles to move toward the direction of the small pores, so that these bubbles can continue to rise. By setting a crushing mechanism, large bubbles are broken, which increases the contact area between the gas and the potassium permanganate solution and also slows down the rising speed of the bubbles, so that formaldehyde can fully react with the potassium permanganate solution, which is beneficial to the purification of formaldehyde. It should be noted that the bubbles are affected by the buoyancy of water in water. The larger the bubbles are, the greater the buoyancy they are subjected to, and the faster the bubbles rise.

[0010] Preferably, the anti-blocking mechanism includes a filter screen, a push plate, a poking pin, a connecting belt, a roller shaft, a movable groove and a No. 2 spring. The filter screen is fixedly inserted on the right side of the interior of the filter chamber, and the movable groove is opened on the upper left side of the No. 2 support plate near the front and rear ends. The push plate is movably inserted between the No. 1 support plate and the No. 2 support plate, and the push plate is slidably connected to the movable groove. The poking pin is fixedly connected to the left side of the push plate, and the number of the poking pins is multiple groups. The push plate and the poking pin are both matched with the filter screen. The connecting belt is fixedly connected to the right side of the push plate, and the number of the connecting belts is multiple groups. The connecting belt is fixedly connected to the lower part of the left support column. The roller shaft is rotatably inserted on the left side of the interior of the reactor body near the lower end, and the roller shaft is located between the No. 1 support plate and the No. 2 support plate. The roller shaft is movably connected to the connecting belt. The No. 2 spring is movably installed on the right side of the movable groove, and the movable groove is fixedly connected to the lower right part of the push plate.

[0011] Industrial waste gas contains dust. Directly injecting industrial waste gas into potassium permanganate solution will also inject dust into the potassium permanganate solution, causing pollution to the potassium permanganate solution. Since the filter is inserted inside the filter chamber, the industrial waste gas contacts the filter when passing through the filter chamber into the reactor body. When the industrial waste gas passes through the filter, the dust in the industrial waste gas cannot pass through the filter and is retained inside the filter chamber. With the cooperation of the dividing mechanism, when the industrial waste gas flows above the No. 1 support plate, the baffle drives the support column to move upward. Under the elastic force of the No. 2 spring, the No. 2 spring pushes the push plate to slide inside the movable groove and approach the direction of the filter, making the industrial waste gas flow upward. When the poking needle penetrates the filter and the industrial waste gas no longer flows above the No. 1 support plate, the baffle drives the support column to reset downward, thereby pulling the connecting belt, and with the cooperation of the roller, pulling the push plate to separate the poking needle from the filter, so that the industrial waste gas can pass through the filter chamber and enter the interior of the reactor body. By setting an anti-blocking mechanism, the dust in the industrial waste gas is filtered out to prevent the dust from contacting with the potassium permanganate solution and polluting the potassium permanganate solution. It can also prevent the filter from being blocked, thereby ensuring the ventilation efficiency of the filter. At the same time, the industrial waste gas can be intermittently contacted with the potassium permanganate solution, so that the formaldehyde and potassium permanganate solution react more fully, thereby improving the purification efficiency of formaldehyde.

[0012] Preferably, the processing mechanism includes a water tank, a nozzle, an adjustment plate, a collecting box, a filter plate and a capillary tube, the water tank is fixedly installed at the upper end of the filter chamber, the nozzle is movably installed at the lower part of the water tank, and the nozzle passes through the upper part of the filter chamber and extends to the interior of the filter chamber, the adjustment plate is movably inserted between the water tank and the nozzle, and the adjustment plate cooperates with the nozzle, the adjustment plate is fixedly connected to the push plate, the collecting box is movably installed at the lower end of the filter chamber, and the collecting box is connected to the filter chamber, and a filter plate is movably inserted in the interior of the collecting box near the upper end, and the filter plate is V-shaped.

[0013] The dust in the industrial waste gas is filtered inside the filter chamber, but will be scattered by the wind, injecting water into the water tank. With the cooperation of the anti-blocking mechanism, when the push plate moves toward the filter screen, it drives the adjustment plate to move, so that the water inside the water tank can be sprayed into the filter chamber through the nozzle, and the dust inside the filter chamber is flushed into the adjustment plate. When the dust-containing water passes through the filter plate, the dust cannot pass through the filter plate, and the water reaches the bottom of the collection box through the filter plate. Under the action of capillary phenomenon, the water inside the collection box can be sucked back into the water tank by the capillary. By setting up a processing mechanism, it is convenient to flush the filtered dust from the inside of the filter chamber to avoid dust accumulation inside the filter chamber and cause blockage. At the same time, it also realizes the recycling of water resources and the full utilization of resources.

[0014] Preferably, the scraping mechanism comprises a fixed rod, a wavy spring piece and a scraper, the fixed rod is fixedly inserted in the filter chamber, and the number of the fixed rods is three groups, the upper and lower ends of the fixed rod are movably mounted with wavy spring pieces, the end of the wavy spring piece away from the fixed rod is movably mounted with a scraper, and the scraper is slidably connected to the inner wall of the filter chamber;

[0015] The scraping mechanism also includes an elastic rope and a small ball. The elastic rope is movably inserted at the upper and lower ends of the filter chamber, and the number of the elastic ropes is six groups. The small ball is fixedly sleeved on the outer surface of the elastic rope, and the number of the small ball is multiple groups. The small ball cooperates with the wavy spring piece.

[0016] The dust in industrial waste gas is easy to adhere to the inner wall of the filter chamber. Under the action of the fixed rod, when the industrial waste gas is blown into the inside of the filter chamber through the air inlet pipe, the wavy spring pieces will be blown into an arc shape. In this process, the wavy spring pieces drive the scraper to move inside the filter chamber, thereby cleaning the inner wall of the filter chamber. At the same time, the wavy spring pieces collide with the small balls. With the cooperation of the elastic rope, the small balls repeatedly collide between the wavy spring pieces, which is convenient for shaking off the dust adhered to the wavy spring pieces. By setting up a scraping mechanism, it is convenient to scrape the inner wall of the filter chamber to avoid dust adhering to the inner wall of the filter chamber and affecting the ventilation efficiency. At the same time, the dust adhered to the wavy spring pieces can also be shaken off, which is conducive to keeping the inside of the filter chamber clean.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting a splitting mechanism, the existing way of air intake through one pipe is changed, and the industrial waste gas is divided into multiple parts, and contacts with potassium permanganate solution from various places at the bottom, so that the industrial waste gas contacts with potassium permanganate solution more fully, which is beneficial to purify formaldehyde and improves the efficiency of formaldehyde purification. By setting a crushing mechanism, large bubbles are crushed, the contact area between gas and potassium permanganate solution is increased, and the rising speed of bubbles is also slowed down, so that formaldehyde can fully react with potassium permanganate solution, which is beneficial to purify formaldehyde;

[0019] 2. By setting up an anti-blocking mechanism, the dust in the industrial waste gas can be filtered out to prevent the dust from contacting with the potassium permanganate solution and polluting the potassium permanganate solution. It can also prevent the filter from being blocked, thereby ensuring the ventilation efficiency of the filter. At the same time, the industrial waste gas can be intermittently contacted with the potassium permanganate solution, so that the formaldehyde and potassium permanganate solution react more fully, thereby improving the purification efficiency of formaldehyde.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figures 1 to 5 , the present invention provides a technical solution:

[0028] A formaldehyde oxidation reactor, such as Figures 1 to 5 As shown, it includes a reactor body 1, a filter chamber 101 is fixedly installed at the lower left part of the reactor body 1, an air inlet pipe 102 is movably installed on the left side of the filter chamber 101, and the reactor body 1, the filter chamber 101 and the air inlet pipe 102 are interconnected, and a splitting mechanism 2 and a crushing mechanism 3 are movably arranged in sequence from bottom to top inside the reactor body 1, and the splitting mechanism 2 and the crushing mechanism 3 cooperate with each other, and an anti-blocking mechanism 4 cooperating with the splitting mechanism 2 is movably arranged at a position near the lower end of the left side of the reactor body 1, and a processing mechanism 5 and a scraping mechanism 6 are movably arranged in sequence from top to bottom inside the filter chamber 101, and the processing mechanism 5 cooperates with the anti-blocking mechanism 4;

[0029] The dividing mechanism 2 includes a No. 1 support plate 201, a No. 2 support plate 202, a support column 203, an air hole 204 and a baffle 205. The interior of the reactor body 1 is fixedly inserted with the No. 1 support plate 201 and the No. 2 support plate 202 from top to bottom near the lower end, and the interior of the reactor body 1 is located above the No. 1 support plate 201 and is filled with potassium permanganate solution. The support column 203 slides through the No. 1 support plate 201 and the No. 2 support plate 202, and the number of the support columns 203 is multiple groups. The air hole 204 is opened on the surface of the No. 1 support plate 201 at a position corresponding to the support column 203, and the air hole 204 cooperates with the support column 203. The baffle 205 is fixedly installed on the upper part of the support column 203, and the baffle 205 cooperates with the air hole 204. The No. 1 spring 206 is movably sleeved on the outer surface of the support rod 203 near the lower end, and the No. 1 spring 206 is fixedly connected to the lower part of the No. 2 support plate 202.

[0030] The crushing mechanism 3 includes a mounting plate 301, a small air hole 302, a threaded rod 303, a threaded block 304 and a mounting block 305. The mounting plate 301 is fixedly inserted in the middle position inside the reactor body 1. The small air hole 302 is provided on the surface of the mounting plate 301, and the number of the small air holes 302 is multiple groups. The threaded rod 303 is fixedly connected to the outer surface of the upper end of the baffle 205, and the threaded rod 303 is slidably connected to the mounting plate 301. The threaded block 304 is threadedly sleeved on the outer surface of the threaded rod 303, and the threaded block 304 is rotatably connected to the lower part of the mounting plate 301. The mounting block 305 is fixedly connected to the outer surface of the threaded block 304, and the number of the mounting block 305 is multiple groups.

[0031] During operation, the pipe for discharging industrial waste gas is generally inserted into the interior of the reactor body 1, so that the industrial waste gas is in contact with the potassium permanganate solution, thereby purifying the formaldehyde in the industrial waste gas. However, in this purification method, the contact area between the gas and the potassium permanganate solution is relatively small, so that the reaction is not sufficient, and thus there is a disadvantage of not purifying the formaldehyde thoroughly enough. Since the No. 1 support plate 201 and the No. 2 support plate 202 are fixedly inserted into the interior of the reactor body 1, the potassium permanganate liquid is filled in the interior of the reactor body 1 above the No. 1 support plate 201, and then the industrial waste gas is discharged into the interior of the filter chamber 101 through the air inlet pipe 102. The industrial waste gas reaches the interior of the reactor body 1 through the filter chamber 101 and is located between the No. 1 support plate 201 and the No. 2 support plate 202. If industrial waste gas is continuously discharged, the air pressure between the No. 1 support plate 201 and the No. 2 support plate 202 will be increased. When the air pressure reaches a certain value, the baffle 205 will be pushed to enter the upper end of the No. 1 support plate 201 through the air hole 204 and contact with the potassium permanganate solution. When the air pressure between the No. 1 support plate 201 and the No. 2 support plate 202 decreases, with the cooperation of the support column 203 and the No. 1 spring 206, and at the same time, under the action of water pressure, the baffle 205 is reset to block the air hole 204 again, so that the industrial waste gas between the No. 1 support plate 201 and the No. 2 support plate 202 cannot reach the top of the No. 1 support plate 201. It should be noted that the pressure of one standard atmospheric pressure is about the same as the pressure at a depth of ten meters. Therefore, When exhausting upward, the potassium permanganate solution inside the reactor body 1 will not flow to the bottom of the first support plate 201 through the large air hole 204. By setting the dividing mechanism 2, the existing way of air intake through a pipe is changed, and the industrial waste gas is divided into multiple parts, and contacts with the potassium permanganate solution from various places at the bottom, so that the industrial waste gas is more fully in contact with the potassium permanganate solution, which is beneficial to purify formaldehyde and improves the efficiency of formaldehyde purification. When the industrial waste gas contacts with the potassium permanganate solution, bubbles will be generated. When the formaldehyde is located inside the bubbles, it cannot fully contact with the potassium permanganate solution. Since the mounting plate 301 is fixedly inserted inside the reactor body 1, when the bubbles rise to the position of the mounting plate 301, the bubbles can only pass through the small air holes. 302 can continue to float up. Since the diameter of the small air hole 302 is relatively small, the bubbles can be divided. With the cooperation of the dividing mechanism 2, the baffle 205 drives the threaded rod 303 to move up and down during the up and down movement. Since the threaded rod 303 is threadedly connected with the threaded block 304, the threaded rod 303 drives the threaded block 304 to rotate during the up and down movement, thereby driving the mounting block 305 to rotate. The mounting block 305 can break the bubbles staying under the mounting plate 301 and drive these bubbles to move toward the direction of the small air hole 302, so that these bubbles can continue to rise. By setting the breaking mechanism 3, large bubbles are broken, the contact area between the gas and the potassium permanganate solution is increased, and the rising speed of the bubbles is also slowed down.This allows formaldehyde to fully react with the potassium permanganate solution, which is beneficial for purifying formaldehyde. It should be noted that bubbles in water are affected by the buoyancy of water. The larger the bubble, the greater the buoyancy, and the faster the bubble rises.

[0032] As an embodiment of the present invention, Figures 1 to 4 As shown, the anti-blocking mechanism 4 includes a filter screen 401, a push plate 402, a poking pin 403, a connecting belt 404, a roller 405, a movable groove 406 and a second spring 407. The filter screen 401 is fixedly inserted on the right side of the filter chamber 101, and the movable groove 406 is opened on the upper left side of the second support plate 202 near the front and rear ends. The push plate 402 is movably inserted between the first support plate 201 and the second support plate 202, and the push plate 402 is slidably connected to the movable groove 406. The poking pin 403 is fixedly connected to the left side of the push plate 402, and the number of the poking pins 403 is multiple groups. 02 and the poking pin 403 are matched with the filter screen 401, the connecting belt 404 is fixedly connected to the right side of the push plate 402, and the number of the connecting belts 404 is multiple groups, the connecting belt 404 is fixedly connected to the lower part of the left support column 203, the roller 405 is rotatably inserted in the left side of the reactor body 1 near the lower end, and the roller 405 is located between the first support plate 201 and the second support plate 202, the roller 405 is movably connected to the connecting belt 404, the second spring 407 is movably installed on the right side of the movable groove 406, and the movable groove 406 is fixedly connected to the lower right side of the push plate 402;

[0033] During operation, the industrial waste gas contains dust. Directly injecting the industrial waste gas into the potassium permanganate solution will also inject the dust into the potassium permanganate solution, causing pollution to the potassium permanganate solution. Since the filter screen 401 is inserted into the interior of the filter chamber 101, the industrial waste gas contacts the filter screen 401 when passing through the filter chamber 101 and entering the interior of the reactor body 1. When the industrial waste gas passes through the filter screen 401, the dust in the industrial waste gas cannot pass through the filter screen 401 and is retained in the interior of the filter chamber 101. With the cooperation of the dividing mechanism 2, when the industrial waste gas flows above the No. 1 support plate 201, the baffle 205 drives the support column 203 to move upward. Under the elastic force of the No. 2 spring 407, the No. 2 spring 407 pushes the push plate 402 to slide inside the movable groove 406 and toward the direction of the filter screen 401. When the industrial waste gas is close to each other, so that the pin 403 penetrates the filter screen 401, and the industrial waste gas no longer flows above the No. 1 support plate 201, the baffle 205 drives the support column 203 to reset downward, thereby pulling the connecting belt 404, and with the cooperation of the roller 405, pulling the push plate 402, so that the pin 403 is separated from the filter screen 401, so that the industrial waste gas can enter the interior of the reactor body 1 through the filter chamber 101, and the anti-blocking mechanism 4 is set to filter out the dust in the industrial waste gas, to prevent the dust from contacting with the potassium permanganate solution and polluting the potassium permanganate solution, and to prevent the filter screen 401 from being blocked, thereby ensuring the ventilation efficiency of the filter screen 401, and at the same time, the industrial waste gas can be intermittently contacted with the potassium permanganate solution, so that the formaldehyde and the potassium permanganate solution react more fully, thereby improving the purification efficiency of the formaldehyde.

[0034] As an embodiment of the present invention, Figures 1 to 5 As shown, the treatment mechanism 5 includes a water tank 501, a nozzle 502, an adjustment plate 503, a collection box 504, a filter plate 505 and a capillary 506. The water tank 501 is fixedly installed at the upper end of the filter chamber 101, and the nozzle 502 is movably installed at the lower part of the water tank 501, and the nozzle 502 passes through the upper part of the filter chamber 101 and extends to the inside of the filter chamber 101. The adjustment plate 503 is movably inserted between the water tank 501 and the nozzle 502, and the adjustment plate 503 cooperates with the nozzle 502. The adjustment plate 503 is fixedly connected to the push plate 402, and the collection box 504 is movably installed at the lower end of the filter chamber 101, and the collection box 504 is connected with the filter chamber 101. The filter plate 505 is movably inserted near the upper end of the collection box 504, and the shape of the filter plate 505 is V-shaped;

[0035] During operation, dust in the industrial waste gas is filtered inside the filter chamber 101, but will be blown around by the wind, and water will be injected into the water tank 501. With the cooperation of the anti-blocking mechanism 4, when the push plate 402 moves toward the filter screen 401, the adjusting plate 503 is driven to move, so that the water inside the water tank 501 can be sprayed into the filter chamber 101 through the nozzle 502, and the dust inside the filter chamber 101 is flushed into the adjusting plate 503. When the water containing dust passes through the filter plate 505, the dust cannot pass through the filter plate 505, and the water passes through the filter plate 505 to the bottom of the collection box 504. Under the action of capillary phenomenon, the water inside the collection box 504 can be sucked back into the water tank 501 by the capillary 506. By setting the processing mechanism 5, it is convenient to flush the filtered dust from the inside of the filter chamber 101, and avoid dust accumulation in the filter chamber 101 to cause blockage. At the same time, it also realizes the recycling of water resources and the full use of resources.

[0036] As an embodiment of the present invention, Figure 3 to Figure 4 As shown, the scraping mechanism 6 includes a fixed rod 601, a wavy spring piece 602 and a scraper 603. The fixed rod 601 is fixedly inserted in the filter chamber 101, and the number of the fixed rods 601 is three groups. The upper and lower ends of the fixed rod 601 are movably mounted with wavy spring pieces 602. The end of the wavy spring piece 602 away from the fixed rod 601 is movably mounted with a scraper 603, and the scraper 603 is slidably connected to the inner wall of the filter chamber 101.

[0037] The scraping mechanism 6 further includes an elastic rope 604 and a small ball 605. The elastic rope 604 is movably inserted at the upper and lower ends of the filter chamber 101, and the number of the elastic rope 604 is six groups. The small ball 605 is fixedly sleeved on the outer surface of the elastic rope 604, and the number of the small ball 605 is multiple groups. The small ball 605 cooperates with the wavy spring piece 602.

[0038] During operation, dust in industrial waste gas is easy to adhere to the inner wall of the filter chamber 101. Under the action of the fixed rod 601, when the industrial waste gas is blown into the inside of the filter chamber 101 through the air inlet pipe 102, the wavy spring piece 602 will be blown into an arc. In this process, the wavy spring piece 602 drives the scraper 603 to move inside the filter chamber 101, thereby cleaning the inner wall of the filter chamber 101. At the same time, the wavy spring piece 602 collides with the small ball 605. With the cooperation of the elastic rope 604, the small ball 605 repeatedly collides between the wavy spring pieces 602, which is convenient for shaking off the dust adhered to the wavy spring piece 602. By setting up the scraping mechanism 6, it is convenient to clean the inner wall of the filter chamber 101, avoid dust adhering to the inner wall of the filter chamber 101, and affect the ventilation efficiency. At the same time, the dust adhered to the wavy spring piece 602 can also be shaken off, which is conducive to keeping the inside of the filter chamber 101 clean.

[0039] Working principle:

[0040] During operation, since the No. 1 support plate 201 and the No. 2 support plate 202 are fixedly inserted in the interior of the reactor body 1, potassium permanganate liquid is filled in the interior of the reactor body 1 above the No. 1 support plate 201, and then the industrial waste gas is discharged into the interior of the filter chamber 101 through the air inlet pipe 102. The industrial waste gas reaches the interior of the reactor body 1 through the filter chamber 101 and is located between the No. 1 support plate 201 and the No. 2 support plate 202. The industrial waste gas is continuously discharged, which increases the air pressure between the No. 1 support plate 201 and the No. 2 support plate 202. When the air pressure reaches a certain value, the baffle 205 is pushed and enters the upper end of the No. 1 support plate 201 through the air hole 204 and contacts with the potassium permanganate solution. When the No. 1 support plate 201 and the No. 2 support plate 202 are in contact with each other, the air pressure between the No. 1 support plate 201 and the No. 2 support plate 202 increases. When the air pressure between the plates 202 decreases, with the cooperation of the support column 203 and the first spring 206, and at the same time, under the action of water pressure, the baffle 205 is reset to block the large air hole 204 again, so that the industrial waste gas between the first support plate 201 and the second support plate 202 cannot reach the top of the first support plate 201. Since the mounting plate 301 is fixedly inserted in the interior of the reactor body 1, when the bubbles rise to the position of the mounting plate 301, the bubbles can only continue to float through the small air holes 302. Since the diameter of the small air holes 302 is relatively small, the bubbles can be divided. With the cooperation of the dividing mechanism 2, the baffle 205 drives the threaded rod 303 to move up and down during the up and down movement. 304 is threadedly connected, and the threaded rod 303 drives the threaded block 304 to rotate during the up and down movement, thereby driving the mounting block 305 to rotate. The mounting block 305 can break the bubbles that remain below the mounting plate 301 and drive these bubbles to move toward the small pores 302. Since the filter screen 401 is inserted into the interior of the filter chamber 101, the industrial waste gas contacts the filter screen 401 when passing through the filter chamber 101 and entering the reactor body 1. When the industrial waste gas passes through the filter screen 401, the dust in the industrial waste gas cannot pass through the filter screen 401 and is retained in the filter chamber 101. With the cooperation of the dividing mechanism 2, when the industrial waste gas flows above the No. 1 support plate 201, the baffle 205 drives the support column 203 to 401, and the industrial waste gas is moved upward. Under the elastic force of the second spring 407, the second spring 407 pushes the push plate 402 to slide inside the movable groove 406 and approach the filter screen 401, so that the pin 403 penetrates the filter screen 401. When the industrial waste gas no longer flows above the first support plate 201, the baffle 205 drives the support column 203 to reset downward, thereby pulling the connecting belt 404. With the cooperation of the roller 405, the push plate 402 is pulled to separate the pin 403 from the filter screen 401, so that the industrial waste gas can enter the interior of the reactor body 1 through the filter chamber 101 again, and water is injected into the interior of the water tank 501. With the cooperation of the anti-blocking mechanism 4, when the push plate 402 moves toward the filter screen 401, it drives the adjustment plate 503 to move.The water in the water tank 501 can be sprayed into the filter chamber 101 through the nozzle 502, and the dust in the filter chamber 101 is washed into the inside of the adjustment plate 503. When the water containing dust passes through the filter plate 505, the dust cannot pass through the filter plate 505, and the water passes through the filter plate 505 to the bottom of the collection box 504. Under the action of capillary phenomenon, the water in the collection box 504 can be sucked back into the water tank 501 by the capillary 506. Under the action of the fixing rod 601, the industrial waste gas is vented. When the air is blown into the filter chamber 101 through the air inlet pipe 102, the wavy spring piece 602 will be blown into an arc shape. In this process, the wavy spring piece 602 drives the scraper 603 to move inside the filter chamber 101, thereby cleaning the inner wall of the filter chamber 101. At the same time, the wavy spring piece 602 collides with the small ball 605. With the cooperation of the elastic rope 604, the small ball 605 repeatedly collides between the wavy spring pieces 602, which facilitates the dust adhering to the wavy spring piece 602 to fall off.
