Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to an environmentally friendly modular waste gas purification device. Background Art

[0002] Waste gas emitted from industrial production often has harmful effects on the environment and human health. Purification measures should be taken before it is discharged into the atmosphere to make it meet the requirements of waste gas emission standards. This process is called waste gas purification. In waste gas treatment, commonly used equipment include spray towers, activated carbon adsorption equipment, oil fume purifiers, waste gas deodorization equipment, dust removal equipment, centrifugal fans, and some supporting electric control switches and pipelines.

[0003] Chinese patent CN217613970U discloses a spray tower with automatic cleaning function, which includes a tower body, a spray system and a cleaning system. A plurality of filter baffles are arranged in the tower body at intervals along the up and down directions, and each filter baffle is filled with fillers. The spray system includes a plurality of spray devices, and a spray device is arranged above at least one layer of fillers. The cleaning system includes a plurality of spray devices and a plurality of stirring devices, and a spray device is arranged below each filter baffle. The stirring device is buried in the filler, and the stirring device can stir the filler. The stirring device breaks up the dust or crystals adhering to the filler, and the spray device flushes the dust and crystals retained on the filler from the filler, thereby achieving the effect of cleaning the filler and the inner wall of the cylinder body. The cleaning process does not require manual participation, and there is no need to disassemble the spray tower for cleaning, which effectively improves the cleaning efficiency and effect, avoids shutdown for cleaning, and improves the working efficiency of the spray tower.

[0004] The above solution still has the following problems in practical application:

[0005] In the above scheme, the inner wall of the tower body is cleaned by flushing with water sprayed from a spraying device. Since some impurities in the industrial waste gas have a certain degree of adhesion after combining with water, they adhere to the inner wall of the tower body. Conventional spray heads spray from top to bottom when spraying water, which makes it difficult to flush the adherent impurities on the inner wall of the tower body. The spray head is directly exposed to the inside of the spray tower and is contaminated by the waste gas impurities in the tower for a long time, which can easily lead to blockage of the liquid outlet of the spray head, affecting the spray purification effect.

[0006] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0007] 1. Technical issues to be resolved

[0008] In view of the deficiencies in the prior art, the present invention provides an environmentally friendly modular exhaust gas purification device. Through the arrangement of a cross nozzle, the spraying direction of the water flow is horizontal spraying, so as to flush the inner wall of the cabin. The arrangement of the connecting component drives the driving component and the rotating sleeve to operate simultaneously. The operation of the driving component drives multiple movable rotating plates on the top of the grille plate to rotate and reciprocate simultaneously, so as to clean the top of the grille plate, the rotating sleeve and the inner wall of the cabin. This solves the problem that most of the conventional spray tower cleaning is done manually on a regular basis, and the spray tower needs to be disassembled for cleaning, which is cumbersome to operate. The spray heads in the spray tower all spray in a fan shape from top to bottom when spraying water, making it difficult to flush away the adherent impurities on the inner wall of the tower body.

[0025] Beneficial Effects

[0026] Compared with the prior art, the present invention provides an environmentally friendly modular exhaust gas purification device, which has the following beneficial effects:

[0027] 1. The present invention drives the driving component and the rotating sleeve to operate simultaneously through the setting of the connecting component. The operation of the driving component drives multiple movable rotating plates on the top of the grid plate to rotate simultaneously and reciprocate. When the movable rotating plate moves toward one side of the rotating sleeve, the movable rotating plate rotates itself, so that the outer surface of the rotating sleeve is wiped and cleaned by the cleaning brushes on both sides. When the movable rotating plate moves toward the inner wall of the cabin, the movable rotating plate rotates itself, so that the inner wall of the cabin is wiped and cleaned by the cleaning brushes on both sides, thereby cleaning the rotating sleeve and the inner wall of the cabin, solving the problem that most of the conventional spray tower cleaning is regular manual cleaning, and the spray tower needs to be disassembled for cleaning, which is troublesome to operate. The spray head in the spray tower sprays water in a fan shape from top to bottom when spraying, and it is difficult to rinse off the adherent impurities on the inner wall of the tower body.

[0028] 2. The present invention utilizes the contact between the round rod and the protective sleeve so that the protective sleeve is squeezed by the round rod and the elastic part is compressed. When the elastic part is fully compressed, the round rod can slide over the outside of the protective sleeve. When the round rod is separated from the protective sleeve, the elastic part with stored force can pop out quickly to drive the protective sleeve to reset. The vibration generated by the instantaneous popping out of the elastic part shakes the impurities adhered to the water outlet end outside the protective sleeve, so that some impurities adhered to the water outlet end of the cross nozzle can fall directly, and the adhesion of the remaining impurities to the protective sleeve can also be reduced under the action of vibration. Subsequently, the residual impurities are cleaned by the movement of the cleaning brush, thereby further clearing the blockage of the water outlet end outside the protective sleeve and ensuring the spraying effect of the cross nozzle.

[0029] 3. The present invention scrapes and cleans the top of the grille plate by means of the elastic material at the bottom of the movable rotating plate while the movable rotating plate is moving and rotating. At the same time, the cleaning brushes at the adjacent ends of the two movable rotating plates are staggered so that the two crossed cleaning brushes can clean each other.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0040] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes an environmentally friendly modular exhaust gas purification device.

[0041] See also Figure 1 - Figure 8 , an environmentally friendly modular exhaust gas purification device, comprising a cabin 1, a plurality of spray purification units are evenly arranged inside the cabin 1, and a cleaning mechanism 7 is arranged on each of the spray purification units, characterized in that: the spray purification unit comprises a grid plate 2, a water filter plate 3, and a cross nozzle 6, a filler is filled between the grid plate 2 and the water filter plate 3, which is used to absorb some impurities in the exhaust gas, a rotating sleeve 4 and a fixed sleeve 12 which can rotate relatively are arranged at the axis of the grid plate 2, and the cross nozzle 6 is fixedly installed at the intersection of the rotating sleeve 4 and the fixed sleeve 12, and the cleaning liquid is sprayed by the cross nozzle 6 to clean the inside of the cabin 1;

[0042] The rotating sleeve 4 is driven to rotate by the driving assembly 9. The surface of the rotating sleeve 4 is evenly provided with stirring rods, which are located between the grid plate 2 and the water filter plate 3. After the exhaust gas enters the cabin 1, it passes through multiple groups of spray purification units in sequence. The rotating sleeve 4 is driven to rotate by the driving assembly 9 to drive the stirring rods to stir the filler. With the spraying effect of the cross nozzle 6, the filler can fully contact and react with the exhaust gas passing through, thereby improving the adsorption and purification effect of the filler on some impurities in the exhaust gas, and at the same time achieving the effect of cleaning the filler and the inner wall of the cabin 1. A round rod 10 is evenly fixed at the top edge of the rotating sleeve 4. The outer sides of the four water outlet ends of the cross nozzle 6 are respectively provided with protective sleeves 11 through elastic pieces. During the rotation of the rotating sleeve 4, when the elastic piece is fully contracted, the protective sleeve 11 can slide over the inner side of the round rod 10. Specifically, the elastic piece can be a spring, and the outer side of the protective sleeve 11 is a spherical surface. During the rotation of the rotating sleeve 4 driving the round rod 10, when the round rod 10 and the protective sleeve 11 are rotated, After the contact, as the round rod 10 continues to slide relative to the spherical surface of the protective sleeve 11, the protective sleeve 11 is squeezed and the elastic member is compressed. When the elastic member is fully compressed, the round rod 10 can slide over the outside of the protective sleeve 11, and when the round rod 10 is separated from the protective sleeve 11, the elastic member with stored force can be quickly ejected to drive the protective sleeve 11 to reset. The vibration generated by the instantaneous ejection of the elastic member shakes the impurities adhered to the water outlet end of the outer side of the protective sleeve 11, so that some impurities adhered to the water outlet end of the cross nozzle 6 can fall directly, and the adhesion of the remaining impurities to the protective sleeve 11 can also be reduced under the action of vibration. Then, the round rod 10 is driven to rotate continuously by rotating the sleeve 4, so that the outer side of the protective sleeve 11 is intermittently vibrated, so as to directly shake off or reduce the adhesion of the impurities adhered to the outer side of the protective sleeve 11, so as to prevent the water outlet end of the cross nozzle 6 from being blocked by impurities, so that the four water outlet spray holes of the cross nozzle 6 can remain exposed, and ensure that the spray purification work can be carried out normally;

[0043] A cleaning mechanism 7 is provided on the top of the grille plate 2. The cleaning mechanism 7 includes a plurality of movable rotating plates 71 distributed in a circle. Cleaning brushes 72 are fixedly provided on both sides of the movable rotating plates 71. The cleaning brushes 72 on two adjacent movable rotating plates 71 are staggered with each other. During the synchronous rotation of the two adjacent movable rotating plates 71, the adjacent cleaning brushes 72 move in a staggered manner, and the bristles generate horizontal friction with each other, so that some impurities attached to the cleaning brushes 72 can be brushed off, so that the cleaning brushes 72 can maintain a good cleaning effect on the impurities. The driving component 9 can drive each movable rotating plate 71 to move and rotate simultaneously through the linkage component 8;

[0044] When the movable rotating plate 71 moves to one end close to the rotating sleeve 4, the movable rotating plate 71 keeps rotating at the same time, driving the cleaning brush 72 to rotate. When the cleaning brush 72 is in close contact with the outer wall of the rotating sleeve 4, it can clean the outer wall of the rotating sleeve 4 and the outer side of the protective sleeve 11, so that impurities adhered to the outer wall surface of the rotating sleeve 4 can be swept off in time, and the protective sleeve 11 has achieved direct shaking off or reduced adhesion of impurities on the outer side with the cooperation of the round rod 10 and the elastic member. The cleaning brush 72 sweeping from the outside of the protective sleeve 11 can further clean the impurities on the surface of the protective sleeve 11 whose adhesion has been reduced, which helps to improve the smooth performance of the four water outlet ends of the cross nozzle 6 during spraying. When the movable rotating plate 71 moves to the end away from the rotating sleeve 4, the cleaning brush 72 can clean the inner wall of the cabin 1, and its bottom end can clean the upper surface of the grille plate 2 during the movement of the movable rotating plate 71, thereby improving the versatility of cleaning the interior of the cabin 1.

The reciprocating screw 85 drives the sliding seat 86 and the bearing seat 83 to reciprocate, thereby driving the movable rotating plate 71 on the top of the worm gear 81 to reciprocate along the slide groove 73. When the reciprocating screw 85 rotates, the telescopic rod 84 rotates and drives the worm 82 to rotate. The rotation of the worm 82 drives the worm gear 81 and the movable rotating plate 71 on the top of the worm gear 81 to rotate.

Since one end of the worm 82 is connected to the telescopic rod 84 with a telescopic structure, the sliding seat 86 drives the bearing seat 83 and the top worm wheel 81 and the worm 82 to reciprocate when performing reciprocating motion, thereby driving the movable rotating plate 71 at the top of the worm wheel 81 to reciprocate. When the telescopic rod 84 rotates, it drives the worm 82 to rotate, and drives the worm wheel 81 to rotate through the meshing connection between the worm 82 and the worm wheel 81, thereby driving the connecting rod 74 at the top of the worm wheel 81 and the movable rotating plate 71 to rotate, that is, the movable rotating plate 71 rotates while performing reciprocating motion in the inner cavity of the slide groove 73.

When the movable rotating plate 71 moves toward the inner wall of the cabin body 1, the movable rotating plate 71 rotates itself, so that the inner wall of the cabin body 1 is wiped and cleaned by the cleaning brushes 72 on both sides. At the same time, when the movable rotating plate 71 moves and rotates, the elastic material at the bottom of the movable rotating plate 71 is used to scrape and clean the top of the grille plate 2;

[0065] Specifically, by connecting the two ends of the fixed rod 910 with the annular plate 98 and the rotating sleeve 4 respectively, the annular plate 98 drives the rotating sleeve 4 to rotate when it rotates. When the rotating sleeve 4 rotates, after the round rod 10 contacts the protective sleeve 11, the protective sleeve 11 is squeezed by the round rod 10 and the elastic member is compressed. When the elastic member is fully compressed, the round rod 10 can slide over the outside of the protective sleeve 11, and when the round rod 10 is separated from the protective sleeve 11, the elastic member with stored force can be quickly ejected to drive the protective sleeve 11 to reset. The vibration generated by the instantaneous ejection of the elastic member shakes the impurities adhered to the water outlet end outside the protective sleeve 11, so that some impurities adhered to the water outlet end of the cross nozzle 6 can fall directly, and the adhesion of the remaining impurities to the protective sleeve 11 can also be reduced under the action of vibration. Subsequently, the residual impurities are cleaned by the movement of the cleaning brush 72, so as to further realize the unblocking of the water outlet end outside the protective sleeve 11 and ensure the spraying effect of the cross nozzle 6.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
