Description

[0001] The present invention belongs to the technical field of air pollution control, and specifically relates to an air environmental pollution control device. Background Art

[0002] There are many types of air pollutants, which can be classified into dust and gaseous pollutants according to their existing characteristics. When the concentration of pollutants in the gas reaches a harmful level, it will affect the normal life and development of humans and cause damage to the ecological environment. Therefore, before the gas is discharged, it must be treated to separate the harmful pollutants from the gas until it meets the emission standards before it can be discharged.

[0003] A Chinese patent with the publication number CN117861366A discloses an air pollution control device, which includes a housing, a ventilation cylinder, a sealing component, a first filtering component, a first collecting member, and a second filtering component. The gas enters the lower cavity from the intake pipe, and the solid pollutants in the gas are intercepted by the first filtering component. The gas enters the upper cavity through the ventilation pipe, and the solid pollutants in the gas are intercepted by the second filtering component, and finally discharged into the atmosphere from the exhaust pipe; during the operation of the device, the switching component continuously changes the states of the two first filter meshes, alternately in the unfolded state to filter the solid pollutants in the gas; when the first filter mesh changes from the unfolded state to the retracted state, the solid pollutants attached to the lower surface of the first filter mesh are shaken off and fall into the first collecting member. It realizes the cleaning of the first filter mesh while filtering, improves the separation efficiency, and the first filter mesh can always maintain the best filtering effect, avoiding the situation that the separation effect is not good due to the large amount of solid pollutants attached to the first filter mesh.

[0004] In the above technology, the filtering effect of the first filter mesh is ensured by cleaning the first filter mesh. In fact, the air pollutants contain acidic gases, such as sulfurous gases, nitrogen oxides, chlorides, etc. produced by industrial production. Acidic gases have a certain corrosive effect in a humid environment and are easy to damage the protective film on the metal surface. The metal components in the first filtering component are corroded, unable to realize the switching between the unfolded and retracted states, and it is not easy to shake off the air pollutants.

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0024] As Figures 1 to 3 and Figure 6 shown, an air environmental pollution treatment device according to an embodiment of the present invention includes: a pretreatment tank 1; a filter tank 2 fixedly connected to the bottom of the pretreatment tank 1; a processing cylinder 3 connected and fixedly connected to the top of the processing tank; an atomizing unit provided in the pretreatment tank 1 for neutralizing and settling air pollutants; the atomizing unit includes a water inlet pipe 11, a water delivery pipe 13, an atomizing nozzle 15 and a corrugated plate 16; the bottom end of the pretreatment tank 1 is connected and fixedly connected with an air inlet pipe 12, and a first valve 121 is installed on the air inlet pipe 12; the inner wall of the top end of the pretreatment tank 1 is fixedly connected with a top plate 14, four water delivery pipes 13 are connected and fixedly connected to the pretreatment tank 1, and a plurality of atomizing nozzles 15 are linearly arranged and installed at the bottom of the water delivery pipe 13; the water delivery pipes 13 are all arranged above the top plate 14 and are connected and fixedly connected to the water inlet pipe 11 at one end; a plurality of corrugated plates 16 are linearly arranged and fixedly connected to the inner wall of the pretreatment tank 1.

[0025] In the prior art, the filtering effect of the first filter screen is ensured by cleaning the first filter screen. In fact, the atmospheric pollutants contain acidic gases, such as sulfurous gases, nitrogen oxides, chlorides, etc. generated by industrial production. In a humid environment, the acidic gases have a certain corrosive effect and are likely to damage the protective film on the metal surface. The metal components in the first filtering assembly are corroded, and the switching between the unfolded and folded states cannot be achieved, and it is not easy to shake off the atmospheric pollutants. When the atomization unit provided by the present invention is in use, first, the alkali liquid is conveyed to the water delivery pipe 13 through the water inlet pipe 11. The alkali liquid in the water delivery pipe 13 forms water mist through the atomizing nozzle 15 and is sprayed in the pretreatment tank 1. Under the action of gravity, the water mist gradually moves towards the bottom of the pretreatment tank 1. Then, by opening the first valve 121, the atmospheric pollutants enter the pretreatment tank 1 from the air inlet pipe 12. The atmospheric pollutants gradually flow into the communicating pipe 374 at the top end of the pretreatment tank 1 under the action of air pressure. During the flowing process, the flowing direction of the water mist is opposite to that of the atmospheric pollutants, so that the water mist contacts and reacts with the atmospheric pollutants, and the acidic gas undergoes a neutralization reaction to form salt and water. In addition, the large particle impurities form viscous impurities under the viscous action of water. At the same time, since the wave plates 16 are fixedly installed in the pretreatment tank 1 and are evenly distributed, both the water mist and the atmospheric pollutants pass through the air flow channels formed by the gaps between the wave plates 16, increasing the contact time between the water mist and the atmospheric pollutants. And the wave plates 16 provide an attachment surface for the water mist, the atmospheric pollutants and the particle impurities, so that the water mist, the atmospheric pollutants and the particle impurities are all fixed on the wave plates 16, thereby achieving the filtering effect of neutralizing and settling the atmospheric pollutants. The filtered gas continues to flow upward. When passing through the second filter cartridge 34, the second filter cartridge 34 is provided with water-absorbing silica gel to absorb the moisture in the gas. Then it passes through the first filter cartridge 33 to filter out the small particle impurities in the atmospheric pollutants and separate the atmospheric pollutants from the gas until the emission standard is met and then it is discharged. Among them, by arranging the wave plates 16, numerous small vortices will be formed during the flow of the gas between the wave plates 16. These vortices fully mix the acidic gas molecules and the alkali liquid droplets, enhancing the turbulence degree between the gas and the liquid, further strengthening the mass transfer process, and making the reaction between the acidic gas and the alkali liquid more complete. The surface of the atomized atmospheric pollutants will be attached with water molecules. Since the atmospheric pollutants will generate salt and water after the neutralization reaction, and the salt is easily soluble in water, the water molecules will contain saline substances. Therefore, when the gas flows upward, the water containing saline substances flows upward with the biological substances of the atmospheric pollutants. When passing through the water-absorbing silica gel, the water-absorbing silica gel absorbs the moisture and will remove the saline substances at the same time, reducing air pollution. During the actual working process, water mist can be formed in the area above the corrugated plate 16. However, since the corrugated plate 16 is set as a corrugated surface, it has multiple barriers to the atomized lye, resulting in the lye adhering to the corrugated plate before reaching the area below the corrugated plate 16. Therefore, the neutralization reaction may not occur in the area below the corrugated plate 16. By installing a pressure booster valve on the atomizing nozzle 15, the pressure of the lye can be accurately increased to an appropriate range. When the pressure of the lye is within this appropriate range, when the lye is ejected from the atomizing nozzle 15, it can be more evenly and finely dispersed into tiny droplets, thus greatly improving the atomization effect. And under the conditions of the gravity of the lye and the pressure of the pressure booster valve, the range of the lye water mist is effectively increased, the area of the lye neutralization reaction is increased, and the efficiency of the lye neutralization reaction is increased.

[0026] As Figure 3 and Figure 4 shown, a reciprocating lead screw 171 is rotatably connected to the inner wall of the pretreatment tank 1 through a bearing. One end of the reciprocating lead screw 171 extends outside the pretreatment tank 1 and is equipped with a first motor 17. A cleaning plate 173 is threadedly connected to the reciprocating lead screw 171. Four guide rods 172 are fixedly connected to the inner wall of the pretreatment tank 1. The four corners of the cleaning plate 173 are respectively slidably connected to the guide rods 172; the cleaning plate 173 is inserted outside the corrugated plate 16; both ends of the cleaning plate 173 are fixedly connected with cleaning brushes 174. The upper cleaning brush 174 contacts the atomizing nozzle 15, and the lower cleaning brush 174 contacts the bottom of the pretreatment tank 1.

[0027] When the cleaning plate 173 and the cleaning brush 174 provided by the present invention are in use, particulate impurities formed by air pollutants fall on the corrugated plate 16. By turning on the first motor 17, the first motor 17 drives the reciprocating lead screw 171 to rotate through the output shaft. The reciprocating lead screw 171 drives the cleaning plate 173 to reciprocate. The particulate impurities on the corrugated plate 16 are scraped by the cleaning plate 173 and finally agglomerate into large particles, and under the action of gravity, they fall downward along the inclined surface of the corrugated plate 16 to the bottom of the pretreatment tank 1. Since the bottom of the pretreatment tank 1 is inclined, under the action of a cleaning brush 174 below, and in cooperation with the accumulated water droplets of the water mist, they will finally fall into the filtration tank 2 through the material dropping port 28; during the movement of the upper cleaning brush 174, the atomizing nozzle 15 is cleaned to prevent small particulate impurities from adhering to the atomizing nozzle 15 and affecting the spraying of the atomizing nozzle 15.

[0028] As Figure 2 and Figure 7As shown in the figure, a first filter cartridge 33 and a second filter cartridge 34 are provided inside the treatment cylinder 3. The second filter cartridge 34 is fixedly connected to the inner wall of the bottom of the first filter cartridge 33, and silica gel for water absorption is provided inside the second filter cartridge 34. A clamping seat 334 is fixedly connected to the inner wall of the treatment cylinder 3. A fixed clamping ring 333 is fixedly connected to the outer wall of the first filter cartridge 33. The fixed clamping ring 333 is clamped inside the clamping seat 334, and a sealing ring 335 is provided between the fixed clamping ring 333 and the clamping seat 334.

[0029] When the fixed clamping ring 333 and the clamping seat 334 provided by the present invention are in use, the first filter cartridge 33 is installed on the clamping seat 334 through the fixed clamping ring 333. The sealing ring 335 is provided to seal the upper and lower cavities of the clamping seat 334, preventing unfiltered air pollutants from overflowing from the gap between the clamping seat 334 and the fixed clamping ring 333. By providing the second filter cartridge 34 with silica gel for water absorption inside, the moisture in the gas is absorbed. By providing the first filter cartridge 33, small particle impurities in the air pollutants are filtered.

[0030] As Figure 2 、 Figure 6 and Figure 8 shown, a cover plate 31 is installed at the top of the treatment cylinder 3. A second motor 311 is fixedly connected to the cover plate 31. A rotating rod 312 is fixedly connected to the output shaft of the second motor 311. A scraping rod 313 is fixedly connected to the outer wall of the rotating rod 312. The scraping rod 313 is in contact with the inner wall of the first filter cartridge 33. An upper sealing plate 32 is fixedly connected to the inner wall of the top of the cover plate 31. The upper sealing plate 32 is clamped with the first filter cartridge 33.

[0031] When the scraping rod 313 provided by the present invention is in use, after being filtered by the first filter cartridge 33, small particle impurities in the air pollutants can be filtered and adsorbed. The small particle impurities adhere to the inner wall of the first filter cartridge 33, resulting in the blockage of the first filter cartridge 33 and reducing the filtering efficiency. By starting the second motor 311, the second motor 311 drives the rotating rod 312 to rotate through the output shaft, drives the scraping rod 313 to rotate through the rotating rod 312, and scrapes the small particle impurities on the inner wall of the first filter cartridge 33 through the scraping rod 313. Among them, the upper sealing plate 32 is clamped with the first filter cartridge 33 to prevent unfiltered air pollutants from overflowing from the gap between the first filter cartridge 33 and the cover plate 31.

[0032] As Figure 2 and Figure 6 shown, a blocking plate 314 and a plurality of stirring paddles 315 are also fixedly connected to the rotating rod 312. The blocking plate 314 covers the top of the second filter cartridge 34. The stirring paddles 315 are all arranged inside the second filter cartridge 34, and the two lower stirring paddles 315 are in contact with the inner wall of the bottom of the first filter cartridge 33.

[0033] When the stirring paddle 315 provided by the present invention is in use, the second motor 311 drives the stirring paddle 315 to rotate through the rotating rod 312. The water-absorbing silica gel in the second filter cylinder 34 is stirred by the stirring paddle 315, so as to quickly dry the moisture in the air pollutants and reduce the moisture in the air pollutants. Moreover, the stirring paddle 315 at the bottom contacts the inner wall of the bottom of the first filter cylinder 33 to prevent the water-absorbing silica gel at the bottom from caking and blocking the ventilation plate 38.

[0034] As Figure 6 shown, a communicating pipe 374 is fixedly connected to the top of the pretreatment box 1. The bottom of the communicating pipe 374 is installed at the bottom of the top plate 14. An electromagnetic valve 375 is installed on the communicating pipe 374. The top of the communicating pipe 374 is installed at the bottom of the treatment cylinder 3.

[0035] When the communicating pipe 374 provided by the present invention is in use, when it is necessary to clean the impurities in the pretreatment box, the electromagnetic valve 375 is closed, which does not affect the treatment of air pollutants in the pretreatment box 1.

[0036] As Figure 6 、 Figure 7 and Figure 10 shown, the top of the communicating pipe 374 is rotatably connected to a connecting pipe 372. The top of the connecting pipe 372 is installed at the bottom of the first filter cylinder 33 and is fixedly connected with a ventilation plate 38. A plugging rod 371 is rotatably connected to the ventilation plate 38. An insertion opening 37 is provided at the bottom of the rotating rod 312. The plugging rod 371 cooperates with the insertion opening 37. Two connecting frames 376 are symmetrically and fixedly connected to the outside of the plugging rod 371, and the connecting frames 376 are fixedly connected to the inner wall of the connecting pipe 372. Two scraping plates 373 are fixedly connected to the outer wall of the connecting pipe 372.

[0037] When the plugging rod 371 and the insertion opening 37 provided by the present invention are in use, through the cooperation of the plugging rod 371 and the insertion opening 37, it is convenient to match the rotating rod 312 and the plugging rod 371. When the rotating rod 312 rotates, it can also drive the plugging rod 371 to rotate. The connecting frame 376 is driven to rotate by the plugging rod 371, the connecting pipe 372 is driven to rotate by the connecting frame 376, the scraping plate 373 is driven to rotate by the connecting pipe 372, and the water-absorbing silica gel or small particle impurities at the bottom of the treatment cylinder 3 are cleaned into the discharge cylinder 36 by the scraping plate 373.

[0038] As Figure 8 and Figure 9 shown, the bottom of the first filter cylinder 33 is communicated and fixedly connected with a first discharge pipe 336 and a second discharge pipe 341. The second discharge pipe 341 is arranged inside the second filter cylinder 34. A first discharge valve 337 is installed on the first discharge pipe 336. A second discharge valve 342 is installed on the second discharge pipe 341. One side of the treatment cylinder 3 is communicated and fixedly connected with a discharge cylinder 36.

[0039] When the first discharge pipe 336 and the second discharge pipe 341 provided by the present invention are in use, when a large amount of small particle impurities inside the first filter cylinder 33 need to be cleaned, the first discharge valve 337 needs to be opened. With the cooperation of the scraping rod 313, the small particle impurities are discharged from the first discharge pipe 336 to the bottom of the treatment cylinder 3, and are cleaned to the discharge cylinder 36 under the action of the scraping plate 373 to complete the cleaning; after the water-absorbing silica gel inside the second filter cylinder 34 has poor water-absorbing ability after being used for a period of time, the second discharge valve 342 needs to be opened. With the cooperation of the stirring paddle 315, the water-absorbing silica gel is discharged from the second discharge pipe 341 to the bottom of the treatment cylinder 3, and is cleaned to the discharge cylinder 36 under the action of the scraping plate 373 to complete the cleaning.

[0040] As Figure 2 and Figure 5 As shown, two side plates 22 are fixedly connected to both inner side walls of the filter box 2. Slide columns 23 are fixedly connected to the tops of the side plates 22, and springs 24 are sleeved on the outer sides of the slide columns 23; a filter plate 21 is slidably connected to the four slide columns 23, and two ends of the spring 24 are fixedly connected between the filter plate 21 and the side plate 22; the filter plate 21 is inclined; a feeding hopper 25 is provided on one inner wall of the bottom of the filter box 2 near the lower end of the filter plate 21; a drain pipe 26 is fixedly connected and communicated on one inner wall of the bottom of the filter box 2 near the upper end of the filter plate 21, and a second valve 27 is installed on the drain pipe 26; a material dropping port 28 is opened on one side of the top of the filter box 2 near the upper end of the filter plate 21.

[0041] When the acidic gas in the air pollutants reacts with the alkali solution by neutralization, the specific gravity of the alkali solution is greater than that of the acidic gas. Therefore, finally the alkali solution will fall along with the pretreated air pollutants. When the filter plate 21 provided by the present invention is in use, under the action of the cleaning brush 174, the pretreated air pollutants, the alkali solution and the water droplets generated by the neutralization reaction fall from the material dropping port 28 onto the filter plate 21. Under the action of the spring 24 and the filter plate 21, the pretreated air pollutants filter the alkali solution and the water droplets on the filter plate 21. The pretreated air pollutants are filtered on the filter plate 21. The filter plate 21 vibrates on the slide column 23, and the pretreated air pollutants slide into the feeding hopper 25. The water droplets and the alkali solution fall to the bottom of the filter box 2 and are finally discharged through the drain pipe 26, which is convenient for recycling and utilization, achieving the effect of dry-wet separation; and a vibrator is arranged at the bottom of the filter plate 21. When the pretreated air pollutants form viscous substances such as sludge and are not convenient for filtering, the vibrator should be started to facilitate the cleaning of the sludge.

[0042] As Figures 1 to 2 As shown, a nitrogen gas pipe 331 is fixedly connected and communicated on the side wall of the first filter cylinder 33. One end of the nitrogen gas pipe 331 penetrates to the outside of the treatment cylinder 3 and is provided with a third valve 332; an air outlet pipe 35 is fixedly connected and communicated on the treatment cylinder 3, and a fourth valve 351 is installed on the air outlet pipe 35.

[0043] When the nitrogen gas pipe 331 provided by the present invention is in use and emergency maintenance is required, there may be residual gas in the treatment cylinder 3. By opening the third valve 332, nitrogen gas is input through the nitrogen gas pipe 331, and the residual gas in the treatment cylinder 3 and the second filter cylinder 34 is discharged from the air outlet pipe 35.

[0044] Working principle: In the prior art, the filtering effect of the first filter screen is ensured by cleaning the first filter screen. In fact, acidic gases are contained in atmospheric pollutants, such as sulfurous gases, nitrogen oxides, chlorides, etc. generated by industrial production. In a humid environment, acidic gases have a certain corrosive effect and are likely to damage the protective film on the metal surface. The metal components in the first filtering assembly are corroded, and the switching between the unfolded and retracted states cannot be achieved, and it is not easy to shake off the atmospheric pollutants. When the atomization unit provided by the present invention is in use, first, the lye is transported to the water delivery pipe 13 through the water inlet pipe 11. The lye in the water delivery pipe 13 forms water mist through the atomizing nozzle 15 and is sprayed in the pretreatment tank 1. Under the action of gravity, the water mist gradually moves towards the bottom of the pretreatment tank 1. Then, by opening the first valve 121, the atmospheric pollutants enter the pretreatment tank 1 from the air inlet pipe 12. The atmospheric pollutants gradually flow towards the communication pipe 374 at the top end of the pretreatment tank 1 under the action of air pressure. During the flowing process, the flowing direction of the water mist is opposite to that of the atmospheric pollutants, so that the water mist contacts and reacts with the atmospheric pollutants, and the acidic gas undergoes a neutralization reaction to form salt and water. In addition, large particle impurities form viscous impurities under the viscous action of water. At the same time, since the wave plates 16 are fixedly installed in the pretreatment tank 1 and are evenly distributed, the water mist and the atmospheric pollutants both pass through the air flow channels formed by the gaps between the wave plates 16, increasing the contact time between the water mist and the atmospheric pollutants. And the wave plates 16 provide an attachment surface for the water mist, the atmospheric pollutants and the particle impurities, so that the water mist, the atmospheric pollutants and the particle impurities are all fixed on the wave plates 16, thereby achieving the filtering effect of neutralizing and settling the atmospheric pollutants. The filtered gas continues to flow upward. When passing through the second filter cylinder 34, the second filter cylinder 34 is provided with water-absorbing silica gel to absorb the moisture in the gas. Then, through the first filter cylinder 33, small particle impurities in the atmospheric pollutants are filtered out, and the atmospheric pollutants are separated from the gas until the emission standard is met and then discharged.

[0045] Atmospheric pollutants form particulate impurities that fall on the corrugated plate 16. By turning on the first motor 17, the first motor 17 drives the reciprocating screw rod 171 to rotate through the output shaft. The reciprocating screw rod 171 drives the cleaning plate 173 to move reciprocally. The cleaning plate 173 scrapes the particulate impurities on the corrugated plate 16, and they will eventually agglomerate into large particles. Under the action of gravity, they will fall downward along the inclined surface of the corrugated plate 16 to the bottom of the pretreatment tank 1. Since the bottom of the pretreatment tank 1 is inclined, under the action of a cleaning brush 174 below and the combined action of the water droplets accumulated by the water mist, they will eventually fall into the filtration tank 2 through the material discharge port 28. During the movement of the upper cleaning brush 174, the atomizing nozzle 15 is cleaned to prevent small particulate impurities from adhering to the atomizing nozzle 15 and affecting the spraying of the atomizing nozzle 15.

[0046] After being filtered by the first filter cylinder 33, small particulate impurities in the atmospheric pollutants can be filtered and adsorbed. The small particulate impurities adhere to the inner wall of the first filter cylinder 33, resulting in the blockage of the first filter cylinder 33 and reducing the filtration efficiency. By turning on the second motor 311, the second motor 311 drives the rotating rod 312 to rotate through the output shaft. The rotating rod 312 drives the scraping rod 313 to rotate, and the scraping rod 313 scrapes the small particulate impurities on the inner wall of the first filter cylinder 33. The upper sealing plate 32 is clamped with the first filter cylinder 33 to prevent unfiltered atmospheric pollutants from overflowing from the gap between the first filter cylinder 33 and the cover plate 31.

[0047] After atomization treatment, water molecules will adhere to the surface of the atmospheric pollutants. Since the atmospheric pollutants will generate salt and water through a neutralization reaction, and the salt is easily soluble in water, the water molecules will contain saline substances. When the gas flows upward, the saline substances in the water will flow upward with the biological substances of the atmospheric pollutants. When passing through the water-absorbing silica gel, the water-absorbing silica gel absorbs the water and will also remove the saline substances, reducing air pollution. The second motor 311 drives the stirring paddle 315 to rotate through the rotating rod 312. The stirring paddle 315 stirs the water-absorbing silica gel in the second filter cylinder 34 to quickly dry the water in the atmospheric pollutants and reduce the water content in the atmospheric pollutants. And the stirring paddle 315 at the bottom contacts the inner wall of the bottom of the first filter cylinder 33 to prevent the water-absorbing silica gel at the bottom from caking and blocking the ventilation plate 38.

[0048] Through the cooperation of the insertion rod 371 and the insertion port 37, it is convenient to combine the rotating rod 312 and the insertion rod 371. When the rotating rod 312 rotates, it can also drive the insertion rod 371 to rotate. The insertion rod 371 drives the connecting frame 376 to rotate, the connecting frame 376 drives the connecting pipe 372 to rotate, the connecting pipe 372 drives the scraping plate 373 to rotate, and the scraping plate 373 cleans the water-absorbing silica gel or small particulate impurities at the bottom of the treatment cylinder 3 into the discharge cylinder 36.

[0049] When the acidic gas in the air pollutants reacts with the alkali solution through neutralization, the specific gravity of the alkali solution is greater than that of the acidic gas. Therefore, finally, the alkali solution will fall along with the pretreated air pollutants. When the filter plate 21 provided by the present invention is in use, under the action of the cleaning brush 174, the pretreated air pollutants, the alkali solution, and the water droplets generated by the neutralization reaction fall from the material dropping port 28 onto the filter plate 21. Under the action of the spring 24 and the filter plate 21, the pretreated air pollutants filter the alkali solution and the water droplets on the filter plate 21. The pretreated air pollutants are filtered on the filter plate 21, and the filter plate 21 vibrates on the sliding column 23. The pretreated air pollutants slide into the blanking hopper 25, and the water droplets and the alkali solution fall to the bottom of the filtering box 2 and are finally discharged through the drain pipe 26, which is convenient for recycling and utilization, achieving the effect of dry-wet separation; and a vibrator is arranged at the bottom of the filter plate 21. When the pretreated air pollutants form viscous substances such as sludge and are not convenient for filtering, the vibrator should be started to facilitate the cleaning of the sludge.
