Description

Technical Field

[0001] The invention relates to the technical field of flue gas treatment, and in particular to an environmentally friendly dust removal type desulfurization and denitrification device. Background Art

[0002] The flue gas emitted by industrial kilns contains a large amount of harmful substances, which pollute the atmosphere, so it needs to be purified. In the prior art, when the flue gas emitted by industrial kilns is desulfurized and denitrated, most of the desulfurization and denitration are carried out in a desulfurization tower. When the desulfurization tower is in use, it is necessary to fill the tower body with fillers, such as expanded clay fillers, plastic fillers, etc., to increase the contact area of ​​the flue gas, and cooperate with the spraying of desulfurization and denitration liquid to ensure the desulfurization and denitration effect of the flue gas. However, when the desulfurization tower is in use, the fillers filled in the tower body need to be cleaned or replaced regularly to ensure the purification of the flue gas. However, the cleaning and maintenance work will directly affect the purification work. Therefore, an environmentally friendly dust removal desulfurization and denitration device is proposed to facilitate the cleaning of the fillers in the tower body. Summary of the invention

[0003] In view of the problems in the prior art, the present invention provides an environmentally friendly dust removal desulfurization and denitrification device to facilitate the cleaning of the fillers in the tower body.

[0004] The technical solution adopted by the present invention to solve the technical problem is an environmentally friendly dust removal desulfurization and denitrification device, comprising a box body, the lower surface of the box body is connected to a smoke inlet pipe, the upper end of the smoke inlet pipe is connected to a horizontally arranged smoke exhaust pipe, the smoke exhaust pipe is connected to the inside of the box body, and the upper outer side of the box body is connected to a horizontally arranged smoke outlet pipe;

[0005] A filtering structure is provided in the box body, a spray structure is provided above the filtering structure, a cleaning structure is provided outside the box body, a feeding structure is provided in the box body, one end of the feeding structure passes through the box body and is located above the cleaning structure, a driving structure is provided above the cleaning structure, and the driving structure is used to drive the feeding structure and the cleaning structure.

[0006] By adopting the above technical solution, the flue gas enters the box body through the smoke inlet pipe and the smoke exhaust pipe. After the flue gas enters the box body, as the flue gas rises, it contacts the filter structure, and relies on the filter material placed in the filter structure to improve the filtering effect of the flue gas. At the same time, the spray structure sprays the desulfurization and denitrification liquid to purify the flue gas and improve the desulfurization and denitrification effect of the flue gas. When the flue gas rises to a certain position in the box body, the flue gas is discharged through the smoke outlet pipe, and the desulfurization and denitrification work of the flue gas is completed at this time.

[0007] When the smoke passes through the filter structure, the smoke will come into contact with the filter material at the bottom. In order to ensure the filtering effect of the filter material, the filter material at the bottom of the filter structure needs to be cleaned. At this time, the driving structure is turned on to drive the feeding structure and the cleaning structure. The feeding structure is used to transport the filter material on the filter structure to the cleaning structure. The filter material is cleaned by the cleaning structure. At the same time, the filter material after cleaning is transported to the box again to ensure the filtering effect of the filter material.

[0008] Specifically, the filtering structure includes an inclined mesh plate, which is located above the smoke inlet pipe, and is provided with filtering material. A plurality of groups of inclined swing plates are provided in the box body, and each of the swing plates is provided with filtering holes that penetrate through the swing plates. The swing plates are hinged to the inner wall of the box body through elastic hinge shafts, and adjacent swing plates are staggered. A first inclined hydraulic telescopic rod is fixedly connected to the lower surface of the swing plate, and the output end of the first hydraulic telescopic rod is hinged to the lower surface of the swing plate, and the fixed end of the first hydraulic telescopic rod is hinged to the inner wall of the box body; the feeding structure is fixedly connected to the upper surface of the lower part of the mesh plate.

[0009] By adopting the above technical solution, the flue gas enters the box and rises, and the flue gas passes through the mesh plate and contacts the filter material above the mesh plate, thereby improving the contact effect between the flue gas and the filter material. At the same time, the spray structure continuously sprays the desulfurization and denitrification liquid to improve the desulfurization and denitrification effect of the flue gas.

[0010] The cleaned filter material is transported into the box by means of the feeding structure and the cleaning structure, and falls on the upper surface of the swing plate at the uppermost layer. The inclined swing plate facilitates the filter material so that the uppermost swing plate rolls down to the swing plate at the lower layer. The filter material rolls down layer by layer, and finally falls on the mesh plate, thereby completing the cleaning and recycling of the filter material. When the flue gas passes through the filter material on the mesh plate, as the flue gas continues to rise, the flue gas contacts the filter material rolling on the swing plate through the filter holes, and the contact effect between the sulfur denitrification liquid and the flue gas can be further improved, and the desulfurization and denitrification effect can be further guaranteed. As the flue gas continues to rise, the flue gas is discharged through the smoke outlet pipe, and the flue gas purification is completed at this time.

[0011] The overall stability of the swing plate can be improved by relying on the first hydraulic telescopic rod;

[0012] It should be pointed out that the filter material described in the present invention can be ceramsite filler or the like.

[0013] Specifically, the spray structure includes a spray plate horizontally installed above the inside of the box, the lower part of the spray plate is connected to a plurality of groups of nozzles, a liquid inlet pipe is installed on the upper surface of the box, the liquid inlet pipe is connected to the inside of the spray plate, and the bottom of the box is connected to the liquid outlet pipe.

[0014] By adopting the above technical scheme, the liquid inlet pipe is connected to the desulfurization and denitrification liquid, and the desulfurization and denitrification liquid enters the spray pipe through the liquid inlet pipe and is sprayed out by the nozzle at the same time, so as to desulfurize and denitrify the flue gas in the box. After the desulfurization and denitrification liquid is sprayed out through the nozzle, the desulfurization and denitrification liquid is sprayed onto the filter material on the swing plate, so that the desulfurization and denitrification liquid can cooperate with the filter material to purify the flue gas.

[0015] Specifically, the feeding structure includes a fixed cylinder obliquely arranged on the outside of the box body, a first spiral feeding shaft is arranged in the fixed cylinder, a fixed block is fixedly connected to the upper surface of the mesh plate, one end of the first spiral feeding shaft is rotatably connected to the fixed block, the other end of the first spiral feeding shaft is provided with a first bevel gear, the first bevel gear is meshed with the driving structure for transmission, one end of the fixed cylinder is located above the mesh plate, and the other end of the fixed cylinder is located above the cleaning structure.

[0016] By adopting the above technical solution, after the smoke enters the box through the smoke inlet pipe, the driving structure is turned on, and the driving structure is engaged with the first bevel gear for transmission, thereby driving the first spiral feeding shaft to rotate. When the first spiral feeding shaft rotates, the filter material on the mesh plate is transported to the top of the cleaning structure, and falls into the cleaning structure through the fixed cylinder. The filter material is cleaned by relying on the cleaning structure, and at the same time, the overall stability of the first spiral feeding shaft can be improved by relying on the fixed block, thereby facilitating the transportation and cleaning of the filter material on the mesh plate and ensuring the filtering effect of the filter material on the smoke.

[0017] Specifically, the cleaning structure includes a cleaning cylinder, a vertically arranged mounting cylinder is fixedly connected in the cleaning cylinder, a second spiral feeding shaft is arranged in the mounting cylinder, the lower end of the second spiral feeding shaft is located at the bottom of the mounting cylinder, a feed port is arranged through the upper surface of the cleaning cylinder, the fixed cylinder is located above the feed port, and the driving structure is located on the upper surface of the mounting cylinder;

[0018] The upper outer side of the mounting tube is connected to an inclined L-shaped feeding pipe, one end of the feeding pipe is connected to the inside of the mounting tube, and the other end of the feeding pipe is connected to the inside of the box body. The end of the feeding pipe away from the mounting tube is located above the uppermost swing plate in the box body;

[0019] A plurality of groups of adjustable cleaning components are arranged in the cleaning cylinder, the adjustable cleaning components are connected to the outside of the installation cylinder, and a plurality of groups of transducers are arranged on the outside of the cleaning cylinder.

[0020] By adopting the above technical scheme, the filter material is discharged from the fixed cylinder and enters the cleaning cylinder through the feed port. The filter material in the cleaning cylinder is cleaned by relying on the adjustable cleaning component and the transducer. After cleaning, the filter material falls on the inner bottom of the cleaning cylinder. At this time, the second spiral feeding shaft is driven by the driving motor to rotate. When the second spiral feeding shaft rotates, the filter material at the bottom of the cleaning cylinder is transported and the filter material is driven to move up in the installation cylinder. When the filter material moves up to a certain position in the installation cylinder, the filter material enters the feeding pipe and is transported into the box by relying on the inclined feeding pipe. The filter material falls on the upper surface of the swing plate located at the uppermost layer. At this time, the cleaning and transportation of the filter material are completed, so as to facilitate the cleaning of the filter material and ensure the purification effect of the flue gas.

[0021] It should be pointed out that the transducer described in the present invention is an ultrasonic transducer, which facilitates ultrasonic cleaning of the filter material in the cleaning cylinder.

[0022] Specifically, the adjustable cleaning assembly includes a sliding ring slidably connected to the outer side of the mounting tube, a first rotating ring is provided above the sliding ring, the first rotating ring is rotatably connected to the outer side of the mounting tube, a first material guide plate arranged upwardly inclined is fixedly connected to the outer side of the first rotating ring, a plurality of groups of first material feed holes are arranged through one end of the first material guide plate close to the first rotating ring, a plurality of groups of first limiting blocks are provided on the lower surface of the first rotating ring, and a plurality of groups of first limiting grooves corresponding to the first limiting blocks are provided on the upper surface of the sliding ring;

[0023] A second rotating ring is provided below the sliding ring, the second rotating ring is rotatably connected to the outer side of the mounting tube, a second material guide plate arranged downwardly and tilted is fixedly connected to the outer side of the second rotating ring, a plurality of groups of second material feeding holes are provided through one end of the second material guide plate away from the second rotating ring, a plurality of groups of second limiting blocks are provided on the upper surface of the second rotating ring, and a plurality of groups of second limiting grooves corresponding to the second limiting blocks are provided on the lower surface of the sliding ring;

[0024] A groove is provided on the inner side of the sliding ring, and a first magnet is installed in the groove. A second magnet and a third magnet are provided on the second spiral feeding shaft. The height of the second magnet is higher than that of the third magnet. A hydraulic adjustment structure is provided on the outer side of the mounting cylinder. The hydraulic adjustment structure is connected to the first hydraulic telescopic rod. The hydraulic adjustment structure is used to drive the sliding ring to move. In the initial state of the hydraulic adjustment structure, the first magnet corresponds to the second magnet, and the first magnet corresponds to the third magnet after the hydraulic adjustment structure is extended.

[0025] By adopting the above technical solution, the filter material enters the first guide plate through the feed inlet, and is driven by the driving motor to rotate the second spiral feed shaft. When the second spiral feed shaft rotates, the second magnet and the first magnet are magnetically attracted to drive the sliding ring to rotate. When the sliding ring rotates, the first limit groove and the first limit block are used to drive the first rotating ring to rotate. When the first rotating ring rotates, it drives the first guide plate to rotate. The centrifugal force generated when the first guide plate rotates drives the filter material to move, thereby reducing the speed at which the filter material moves downward, thereby reducing the moving speed of the filter material on the first guide plate, thereby increasing the cleaning time of the filter material and ensuring the cleaning effect.

[0026] When the smoke intake into the smoke pipe increases, the spraying amount of the desulfurization and denitrification liquid also needs to be increased, and at the same time, the cleaning efficiency of the filter material must also be improved to ensure the desulfurization and denitrification effect on the flue gas; when the spraying amount of the desulfurization and denitrification liquid increases, the desulfurization and denitrification liquid is sprayed to the filter material on the uppermost swing plate, so that the weight of the filter material is further increased, and at this time, the swing plate will be driven to swing further downward and squeeze the first hydraulic telescopic rod, and as the desulfurization and denitrification liquid and the filter material move downward, the other swing plates below will be driven to swing downward, and at this time, the first hydraulic telescopic rod drives the hydraulic adjustment structure to work when it is squeezed; it should be pointed out that the greater the inclination angle of the swing plate, the faster the moving speed of the filter material on the swing plate, so that the moving speed of the filter material on the swing plate can be automatically increased when the spraying amount of the desulfurization and denitrification liquid in the box increases, so as to increase the moving speed of the filter material in the box and ensure the use effect of the filter material;

[0027] The sliding ring is driven to move downward by the hydraulic adjustment structure; during the downward movement of the sliding ring, the distance between the second magnet and the first magnet increases, at which time the magnetic attraction effect of the second magnet on the first magnet decreases, and the driving effect of the second magnet on the sliding ring gradually decreases, thereby gradually reducing the rotation speed of the first guide plate, thereby reducing the influence of the first guide plate on the downward movement speed of the filter material due to rotation, thereby improving the feeding efficiency of the filter material through the first guide plate and the first feed hole;

[0028] When the sliding ring moves down to a certain position, the first limit block of the first rotating ring is disengaged from the first limit groove on the sliding ring, and the second magnet cannot indirectly drive the sliding ring to rotate; when the sliding ring continues to move down to a certain position, the second limit block on the second rotating ring is engaged with the second limit groove on the sliding ring, and the third magnet and the first magnet are magnetically adsorbed, thereby driving the sliding ring to rotate through the third magnet, and thereby driving the second material guide plate to rotate; as the sliding ring moves down, the distance between the third magnet and the first magnet gradually decreases, thereby improving the driving effect of the third magnet on the sliding ring, that is, increasing the rotation speed of the sliding ring; when the filter When the material enters the second guide plate through the first feed hole, the centrifugal force generated by the rotation of the second guide plate can drive the filter material to move, thereby increasing the moving speed of the filter material. The greater the rotation speed of the second guide plate, the faster the moving speed of the filter material on the second guide plate, thereby facilitating rapid conveying of the filter material. At the same time, the cleaned filter material is conveyed into the box through the second spiral feeding shaft and the feeding pipe, thereby improving the conveying efficiency of the filter material, thereby facilitating automatic adjustment of the conveying efficiency of the filter material according to the intake volume of the smoke, thereby ensuring the circulation speed of the filter material and the filtering effect of the filter material.

[0029] When the air intake volume decreases, the spraying volume of the desulfurization and denitrification liquid decreases, and the swing plate swings upward. At this time, the first hydraulic telescopic rod extends, and the hydraulic adjustment structure drives the sliding ring to move upward. During the upward movement of the sliding ring, the second limit block can be disengaged from the second limit groove to make the first limit block on the first rotating ring engage with the first limit groove. Subsequently, the second magnet and the first magnet can be adsorbed to drive the sliding ring and the first rotating ring to rotate, thereby reducing the circulation speed of the filter material and increasing the cleaning time of the filter material, further ensuring the cleaning effect.

[0030] Specifically, the hydraulic adjustment structure includes a sliding ring rotatably connected to a fixed ring on the outside, a second hydraulic telescopic rod fixedly connected to the outside of the mounting cylinder, an output end of the second hydraulic telescopic rod fixedly connected to the upper surface of the fixed ring, a fixed end of the second hydraulic telescopic rod fixedly connected to the outside of the mounting cylinder, and the fixed end of the first hydraulic telescopic rod connected to the second hydraulic telescopic rod through a pipeline.

[0031] By adopting the above technical scheme, when the smoke intake of the smoke inlet pipe increases, the spraying amount of the desulfurization and denitrification liquid also needs to be increased. When the spraying amount of the desulfurization and denitrification liquid increases, it will drive the swing plate to swing downward and squeeze the first hydraulic telescopic rod. When the first hydraulic telescopic rod is squeezed, the output end of the second hydraulic telescopic rod is extended through the pipeline, thereby driving the fixed ring to move downward. When the fixed ring moves downward, it drives the sliding ring to move downward synchronously, so as to automatically adjust the cleaning efficiency of the filter material and the circulation speed of the filter material according to the intake amount of the flue gas.

[0032] Specifically, the driving structure includes a driving motor, the driving motor is fixedly connected to the upper surface of the mounting cylinder through a support rod, and the output shaft of the driving motor passes through the mounting cylinder and is fixedly connected to the second spiral feeding shaft;

[0033] A vertically arranged mounting frame is provided on the outside of the mounting cylinder, a vertically arranged driving rod is provided in the mounting frame, a second bevel tooth is provided at the lower end of the driving rod, one end of the first spiral feeding shaft passes through the mounting frame and is rotatably connected to the mounting frame, the first bevel tooth is located in the mounting frame, the first bevel tooth is meshed with the second bevel tooth for transmission, the upper end of the driving rod passes through the mounting frame and is rotatably connected to the mounting frame, the upper end of the driving rod is fixedly connected to the first pulley, the outer side of the output shaft of the driving motor is fixedly connected to the second pulley, and the second pulley and the first pulley are driven by a transmission belt.

[0034] By adopting the above technical solution, the output shaft of the driving motor is used to drive the second pulley to rotate, and when the second pulley rotates, the first pulley is driven to rotate through the transmission belt, and when the first pulley rotates, the driving rod is driven to rotate synchronously, and when the driving rod rotates, the second bevel gear meshes with the first bevel gear for transmission, and drives the first spiral feeding shaft to work, so as to facilitate the conveying of the filter material placed on the screen plate into the cleaning cylinder, and at the same time, the filter material is cleaned by the cleaning cylinder;

[0035] The output shaft of the driving motor drives the second spiral feeding shaft to rotate. When the second spiral feeding shaft rotates, it drives the cleaned filter material to move upward. After the filter material moves up to a certain position, it is discharged through the feeding pipe, thereby improving the convenience of conveying the filter material.

[0036] Specifically, the bottom of the cleaning cylinder is funnel-shaped, the bottom of the cleaning cylinder is connected to a sewage pipe, a horizontally arranged filter plate is fixedly connected to the bottom of the inner side of the cleaning cylinder, and a joint is provided on the upper surface of the cleaning cylinder.

[0037] By adopting the above technical solution, the bottom of the cleaning cylinder is funnel-shaped, which can facilitate the accumulation of filter materials at the bottom of the cleaning cylinder, and at the same time facilitate the second spiral feeding shaft to transport the cleaned filter materials;

[0038] The water source is connected by the joint, and the water enters the cleaning cylinder through the joint, so as to facilitate the cleaning of the filter material; the filter plate can prevent the filter material from being discharged through the sewage pipe, and at the same time facilitate the discharge of sewage through the sewage pipe, thereby ensuring the cleaning effect of the filter material.

DETAILED DESCRIPTION

[0055] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0056] In order to facilitate the cleaning of the filler in the tower body, as an embodiment of the present invention, Figure 1 , Figure 2 As shown, an environmentally friendly dust removal desulfurization and denitrification device according to the present invention comprises a housing 1, the lower surface of the housing 1 is connected with a smoke inlet pipe 2, the upper end of the smoke inlet pipe 2 is connected with a horizontally arranged smoke exhaust pipe 3, the smoke exhaust pipe 3 is connected with the interior of the housing 1, and the upper outer side of the housing 1 is connected with a horizontally arranged smoke outlet pipe 4;

[0057] A filtering structure is provided inside the box body 1, a spray structure is provided above the filtering structure, a cleaning structure is provided outside the box body 1, a feeding structure is provided inside the box body 1, one end of the feeding structure passes through the box body 1 and is located above the cleaning structure, a driving structure is provided above the cleaning structure, and the driving structure is used to drive the feeding structure and the cleaning structure.

[0058] When in use, the flue gas enters the box body 1 through the smoke inlet pipe 2 and the smoke exhaust pipe 3. After the flue gas enters the box body 1, as the flue gas rises, it contacts the filter structure, and relies on the filter material placed in the filter structure to improve the filtering effect of the flue gas. At the same time, the spray structure sprays the desulfurization and denitrification liquid to purify the flue gas and improve the desulfurization and denitrification effect of the flue gas. When the flue gas rises to a certain position in the box body 1, the flue gas is discharged through the smoke outlet pipe 4, and the desulfurization and denitrification work of the flue gas is completed at this time;

[0059] When the smoke passes through the filter structure, the smoke will come into contact with the filter material at the bottom. In order to ensure the filtering effect of the filter material, the filter material at the bottom of the filter structure needs to be cleaned. At this time, the driving structure is turned on to drive the feeding structure and the cleaning structure. The filter material on the filter structure is transported to the cleaning structure by relying on the feeding structure, and the filter material is cleaned by relying on the cleaning structure. At the same time, the filter material after cleaning is transported to the box body 1 again, so as to ensure the filtering effect of the filter material.

[0060] In order to improve the contact effect between smoke and filter material, for example, Figure 4 As shown, the present invention also includes that the filtering structure includes an inclined mesh plate 5, the mesh plate 5 is located above the smoke inlet pipe 2, and the mesh plate 5 is provided with filtering material, and a plurality of groups of inclined swing plates 6 are provided in the box body 1, and the swing plates 6 are provided with filtering holes 7 arranged through them, and the swing plates 6 are hinged to the inner wall of the box body 1 through elastic hinge shafts 8, and the adjacent swing plates 6 are staggered. The lower surface of the swing plate 6 is fixedly connected with an inclined first hydraulic telescopic rod 9, and the output end of the first hydraulic telescopic rod 9 is hinged to the lower surface of the swing plate 6, and the fixed end of the first hydraulic telescopic rod 9 is hinged to the inner wall of the box body 1; the feeding structure is fixedly connected to the upper surface of the lower part of the mesh plate 5.

[0061] When in use, the flue gas enters the box body 1 and rises, and the flue gas passes through the mesh plate 5 and contacts the filter material above the mesh plate 5, thereby improving the contact effect between the flue gas and the filter material. At the same time, the spray structure continuously sprays the desulfurization and denitrification liquid to improve the desulfurization and denitrification effect of the flue gas;

[0062] The cleaned filter material is transported into the box body 1 by means of the feeding structure and the cleaning structure, and falls on the upper surface of the swing plate 6 located at the uppermost layer. The swing plate 6 arranged obliquely is convenient for filtering the material, so that the uppermost swing plate 6 rolls down to the swing plate 6 of the next layer. The filter material finally falls on the mesh plate 5 by means of the layer-by-layer rolling down of the filter material, thereby completing the cleaning and recycling of the filter material. After the flue gas passes through the filter material on the mesh plate 5, as the flue gas continues to rise, the flue gas contacts the rolling filter material on the swing plate 6 by means of the filter holes 7. At this time, the contact effect between the sulfur denitrification liquid and the flue gas can be further improved, and the desulfurization and denitrification effect can be further ensured. As the flue gas continues to rise, the flue gas is discharged through the smoke outlet pipe 4, and the purification of the flue gas is completed at this time.

[0063] The overall stability of the swing plate 6 can be improved by relying on the first hydraulic telescopic rod 9;

[0064] It should be pointed out that the filter material described in the present invention can be ceramsite filler or the like.

[0065] In order to facilitate the desulfurization and denitrification of the flue gas in the box 1, for example, Figure 1 , Figure 2 , Figure 4 As shown, the present invention also includes that the spray structure includes a spray plate 10 horizontally installed above the interior of the box 1, the lower part of the spray plate 10 is connected to a plurality of groups of nozzles 11, a liquid inlet pipe 12 is installed on the upper surface of the box 1, the liquid inlet pipe 12 is connected to the interior of the spray plate 10, and the bottom of the box 1 is connected to a liquid outlet pipe 13.

[0066] When in use, the liquid inlet pipe 12 is connected to the desulfurization and denitrification liquid, and the desulfurization and denitrification liquid enters the spray pipe through the liquid inlet pipe 12 and is sprayed out by the nozzle 11 at the same time, thereby desulfurizing and denitrifying the flue gas in the box body 1. After the desulfurization and denitrification liquid is sprayed out through the nozzle 11, the desulfurization and denitrification liquid is sprayed onto the filter material on the swing plate 6, so that the desulfurization and denitrification liquid can cooperate with the filter material to purify the flue gas.

[0067] In order to facilitate the conveying of the filter material on the screen plate 5, for example, Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the present invention also includes that the feeding structure includes a fixed cylinder 14 obliquely arranged on the outside of the box body 1, a first spiral feeding shaft 15 is arranged in the fixed cylinder 14, a fixed block 16 is fixedly connected to the upper surface of the mesh plate 5, one end of the first spiral feeding shaft 15 is rotatably connected to the fixed block 16, the other end of the first spiral feeding shaft 15 is provided with a first bevel gear 17, the first bevel gear 17 is meshed with the driving structure for transmission, one end of the fixed cylinder 14 is located above the mesh plate 5, and the other end of the fixed cylinder 14 is located above the cleaning structure.

[0068] When in use, after the smoke enters the box body 1 through the smoke inlet pipe 2, the driving structure is turned on, and the driving structure is meshed with the first bevel gear 17 for transmission, thereby driving the first spiral feeding shaft 15 to rotate. When the first spiral feeding shaft 15 rotates, the filter material on the mesh plate 5 is transported to the top of the cleaning structure, and falls into the cleaning structure through the fixed cylinder 14. The filter material is cleaned by relying on the cleaning structure. At the same time, the fixed block 16 can improve the overall stability of the first spiral feeding shaft 15, thereby facilitating the transportation and cleaning of the filter material on the mesh plate 5 and ensuring the filtering effect of the filter material on the smoke.

[0069] In order to facilitate the cleaning of the filter material, for example, Figure 1 , Figure 2 , Figure 4 The present invention also includes that the cleaning structure includes a cleaning cylinder 18, a vertically arranged mounting cylinder 19 is fixedly connected to the cleaning cylinder 18, a second spiral feeding shaft 20 is arranged in the mounting cylinder 19, the lower end of the second spiral feeding shaft 20 is located at the bottom of the mounting cylinder 19, a feed port 49 is arranged through the upper surface of the cleaning cylinder 18, the fixed cylinder 14 is located above the feed port 49, and the driving structure is located on the upper surface of the mounting cylinder 19;

[0070] The upper outer side of the mounting cylinder 19 is connected to an inclined L-shaped feeding pipe 21, one end of the feeding pipe 21 is connected to the inside of the mounting cylinder 19, and the other end of the feeding pipe 21 is connected to the inside of the box body 1. The end of the feeding pipe 21 away from the mounting cylinder 19 is located above the uppermost swing plate 6 in the box body 1.

[0071] The cleaning cylinder 18 is provided with a plurality of groups of adjustable cleaning components, and the adjustable cleaning components are connected to the outside of the mounting cylinder 19 . The outside of the cleaning cylinder 18 is provided with a plurality of groups of transducers 50 .

[0072] When in use, the filter material is discharged from the fixed cylinder 14 and enters the cleaning cylinder 18 through the feed port 49. The filter material in the cleaning cylinder 18 is cleaned by the adjustable cleaning assembly and the transducer 50. After cleaning, the filter material falls on the inner bottom of the cleaning cylinder 18. At this time, the second spiral feeding shaft 20 is driven to rotate by the driving motor 38. When the second spiral feeding shaft 20 rotates, the filter material at the bottom of the cleaning cylinder 18 is transported and the filter material is driven to move up in the installation cylinder 19. When the filter material moves up to a certain position in the installation cylinder 19, the filter material enters the feeding pipe 21. The filter material is transported to the box body 1 by the inclined feeding pipe 21 and falls on the upper surface of the swing plate 6 located at the uppermost layer. At this time, the cleaning and transportation of the filter material are completed, so as to facilitate the cleaning of the filter material and ensure the purification effect of the flue gas.

[0073] It should be noted that the transducer 50 described in the present invention is an ultrasonic transducer 50 , which facilitates ultrasonic cleaning of the filter material in the cleaning cylinder 18 .

[0074] In order to automatically adjust the transmission efficiency of the filter material according to the intake volume of the smoke, for example, Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, the present invention also includes that the adjustable cleaning assembly includes a sliding ring 22 slidably connected to the outer side of the mounting tube 19, a first rotating ring 23 is provided above the sliding ring 22, the first rotating ring 23 is rotatably connected to the outer side of the mounting tube 19, a first material guide plate 24 arranged upwardly inclined is fixedly connected to the outer side of the first rotating ring 23, a plurality of groups of first material feed holes 25 are arranged through one end of the first material guide plate 24 close to the first rotating ring 23, a plurality of groups of first limiting blocks 26 are arranged on the lower surface of the first rotating ring 23, and a plurality of groups of first limiting grooves 27 corresponding to the first limiting blocks 26 are opened on the upper surface of the sliding ring 22;

[0075] A second rotating ring 28 is provided below the sliding ring 22, and the second rotating ring 28 is rotatably connected to the outer side of the mounting tube 19. A second material guide plate 29 arranged downwardly and tilted is fixedly connected to the outer side of the second rotating ring 28. The second material guide plate 29 is provided with a plurality of groups of second feed holes 30 penetratingly arranged at one end away from the second rotating ring 28. The upper surface of the second rotating ring 28 is provided with a plurality of groups of second limiting blocks 31, and the lower surface of the sliding ring 22 is provided with a plurality of groups of second limiting grooves 32 corresponding to the second limiting blocks 31.

[0076] The inner side of the sliding ring 22 is provided with a groove, and the first magnet 33 is installed in the groove. The second spiral feeding shaft 20 is provided with a second magnet 34 and a third magnet 35. The height of the second magnet 34 is higher than the height of the third magnet 35. The outer side of the mounting tube 19 is provided with a hydraulic adjustment structure, and the hydraulic adjustment structure is connected to the first hydraulic telescopic rod 9. The hydraulic adjustment structure is used to drive the sliding ring 22 to move; in the initial state of the hydraulic adjustment structure, the first magnet 33 corresponds to the second magnet 34, and the first magnet 33 corresponds to the third magnet 35 after the hydraulic adjustment structure is extended.

[0077] When in use, the filter material enters the first guide plate 24 through the feed inlet 49, and is driven by the driving motor 38 to drive the second spiral feed shaft 20 to rotate. When the second spiral feed shaft 20 rotates, the second magnet 34 and the first magnet 33 are magnetically attracted to drive the sliding ring 22 to rotate. When the sliding ring 22 rotates, the first limit groove 27 and the first limit block 26 drive the first rotating ring 23 to rotate. When the first rotating ring 23 rotates, it drives the first guide plate 24 to rotate. The centrifugal force generated when the first guide plate 24 rotates will drive the filter material to move, thereby reducing the speed at which the filter material moves downward, thereby reducing the moving speed of the filter material on the first guide plate 24, thereby increasing the cleaning time of the filter material and ensuring the cleaning effect.

[0078] When the smoke intake of the smoke inlet pipe 2 increases, the spraying amount of the desulfurization and denitrification liquid also needs to be increased, and at the same time, the cleaning efficiency of the filter material should also be improved to ensure the desulfurization and denitrification effect of the flue gas; when the spraying amount of the desulfurization and denitrification liquid increases, the desulfurization and denitrification liquid is sprayed to the filter material on the swing plate 6 located on the uppermost layer, so that the weight of the filter material is further increased, and at this time, the swing plate 6 will be driven to swing further downward and squeeze the first hydraulic telescopic rod 9, and as the desulfurization and denitrification liquid and the filter material move downward, the other swing plates 6 below will be driven to swing downward, and at this time, the first hydraulic telescopic rod 9 drives the hydraulic adjustment structure to work when it is squeezed; it should be pointed out that the greater the inclination angle of the swing plate 6, the faster the moving speed of the filter material on the swing plate 6, so that the moving speed of the filter material on the swing plate 6 can be automatically increased when the spraying amount of the desulfurization and denitrification liquid in the box body 1 increases, so as to increase the moving speed of the filter material in the box body 1 and ensure the use effect of the filter material;

[0079] The sliding ring 22 is driven downward by the hydraulic adjustment structure; during the downward movement of the sliding ring 22, the distance between the second magnet 34 and the first magnet 33 increases, at which time the magnetic attraction effect of the second magnet 34 on the first magnet 33 decreases, and the driving effect of the second magnet 34 on the sliding ring 22 gradually decreases, thereby gradually reducing the rotation speed of the first guide plate 24, thereby reducing the influence of the first guide plate 24 on the downward movement speed of the filter material due to the rotation, thereby improving the feeding efficiency of the filter material through the first guide plate 24 and the first feed hole 25;

[0080] When the sliding ring 22 moves down to a certain position, the first limit block 26 of the first rotating ring 23 is disengaged from the first limit groove 27 on the sliding ring 22, and the second magnet 34 cannot indirectly drive the sliding ring 22 to rotate; when the sliding ring 22 continues to move down to a certain position, the second limit block 31 on the second rotating ring 28 is engaged with the second limit groove 32 on the sliding ring 22, and the third magnet 35 and the first magnet 33 are magnetically adsorbed, so that the sliding ring 22 is driven to rotate through the third magnet 35, and the second guide plate 29 is driven to rotate; as the sliding ring 22 moves down, the distance between the third magnet 35 and the first magnet 33 is gradually reduced, so as to improve the driving effect of the third magnet 35 on the sliding ring 22. That is, the rotation speed of the sliding ring 22 is increased; when the filter material enters the second guide plate 29 through the first feed hole 25, the centrifugal force generated by the rotation of the second guide plate 29 can drive the filter material to move, thereby increasing the moving speed of the filter material, and the greater the rotation speed of the second guide plate 29, the faster the moving speed of the filter material on the second guide plate 29, thereby facilitating rapid conveying of the filter material, and at the same time, the cleaned filter material is conveyed to the box body 1 through the second spiral feeding shaft 20 and the feeding pipe 21, thereby improving the conveying efficiency of the filter material, thereby facilitating automatic adjustment of the conveying efficiency of the filter material according to the intake volume of the smoke, thereby ensuring the circulation speed of the filter material and the filtering effect of the filter material;

[0081] When the air intake volume decreases, the spraying volume of the desulfurization and denitrification liquid decreases, and the swing plate 6 swings upward. At this time, the first hydraulic telescopic rod 9 extends, and the hydraulic adjustment structure drives the sliding ring 22 to move upward. During the upward movement of the sliding ring 22, the second limit block 31 can disengage from the second limit groove 32 to make the first limit block 26 on the first rotating ring 23 engage with the first limit groove 27. Subsequently, the second magnet 34 and the first magnet 33 can be adsorbed to drive the sliding ring 22 and the first rotating ring 23 to rotate, thereby reducing the circulation speed of the filter material and increasing the cleaning time of the filter material, further ensuring the cleaning effect.

[0082] In order to facilitate the downward movement of the sliding ring 22, for example, Figure 4 , Figure 6 , Fig. 9 , Fig.10 As shown, the present invention also includes that the hydraulic adjustment structure includes a sliding ring 22 rotatably connected to a fixed ring 36 on the outside, a second hydraulic telescopic rod 37 is fixedly connected to the outside of the mounting cylinder 19, an output end of the second hydraulic telescopic rod 37 is fixedly connected to the upper surface of the fixed ring 36, a fixed end of the second hydraulic telescopic rod 37 is fixedly connected to the outside of the mounting cylinder 19, and the fixed end of the first hydraulic telescopic rod 9 is connected to the second hydraulic telescopic rod 37 through a pipeline.

[0083] During use, when the smoke intake of the smoke inlet pipe 2 increases, the spraying amount of the desulfurization and denitrification liquid also needs to be increased. When the spraying amount of the desulfurization and denitrification liquid increases, it will drive the swing plate 6 to swing downward and squeeze the first hydraulic telescopic rod 9. When the first hydraulic telescopic rod 9 is squeezed, the output end of the second hydraulic telescopic rod 37 is extended through the pipeline, thereby driving the fixed ring 36 to move downward. When the fixed ring 36 moves downward, it drives the sliding ring 22 to move downward synchronously, so as to automatically adjust the cleaning efficiency of the filter material and the circulation speed of the filter material according to the intake amount of the flue gas.

[0084] For example, Figure 2 , Figure 3 The present invention further includes that the driving structure includes a driving motor 38, the driving motor 38 is fixedly connected to the upper surface of the mounting cylinder 19 through a support rod 39, and the output shaft of the driving motor 38 passes through the mounting cylinder 19 and is fixedly connected to the second spiral feeding shaft 20;

[0085] A vertically arranged mounting frame 40 is provided on the outer side of the mounting cylinder 19, a vertically arranged driving rod 41 is provided in the mounting frame 40, a second bevel gear 42 is provided at the lower end of the driving rod 41, one end of the first spiral feeding shaft 15 passes through the mounting frame 40 and is rotatably connected to the mounting frame 40, the first bevel gear 17 is located in the mounting frame 40, the first bevel gear 17 is meshed with the second bevel gear 42 for transmission, the upper end of the driving rod 41 passes through the mounting frame 40 and is rotatably connected to the mounting frame 40, the upper end of the driving rod 41 is fixedly connected to a first pulley 43, a second pulley 44 is fixedly connected to the outer side of the output shaft of the driving motor 38, and the second pulley 44 and the first pulley 43 are transmitted through a transmission belt 45.

[0086] When in use, the output shaft of the driving motor 38 rotates to drive the second pulley 44 to rotate. When the second pulley 44 rotates, the first pulley 43 is driven to rotate through the transmission belt 45. When the first pulley 43 rotates, the driving rod 41 is driven to rotate synchronously. When the driving rod 41 rotates, the second bevel gear 42 engages with the first bevel gear 17 for transmission, and drives the first spiral feeding shaft 15 to work, so as to facilitate the conveying of the filter material placed on the screen plate 5 into the cleaning cylinder 18, and the filter material is cleaned by the cleaning cylinder 18 at the same time;

[0087] The second spiral feeding shaft 20 is driven to rotate by the output shaft of the driving motor 38. When the second spiral feeding shaft 20 rotates, it drives the cleaned filter material to move upward. After the filter material moves up to a certain position, it is discharged through the feeding pipe 21, thereby improving the convenience of conveying the filter material.

[0088] For example, Fig. 9As shown, the present invention also includes that the bottom of the cleaning cylinder 18 is formed into a funnel shape, the bottom of the cleaning cylinder 18 is connected to a sewage pipe 47, a horizontally arranged filter plate 46 is fixedly connected to the bottom of the inner side of the cleaning cylinder 18, and a joint 48 is provided on the upper surface of the cleaning cylinder 18.

[0089] When in use, the bottom of the cleaning cylinder 18 is funnel-shaped, which can facilitate the accumulation of filter materials at the bottom of the cleaning cylinder 18, and at the same time facilitate the second spiral feeding shaft 20 to transport the cleaned filter materials;

[0090] The water source is connected by the joint 48, and the water enters the cleaning cylinder 18 through the joint 48, so as to facilitate the cleaning of the filter material; the filter plate 46 can prevent the filter material from being discharged through the sewage pipe 47, and at the same time facilitate the discharge of sewage through the sewage pipe 47, thereby ensuring the cleaning effect of the filter material.

[0091] When the present invention is in use, the flue gas enters the box body 1 through the smoke inlet pipe 2 and the smoke exhaust pipe 3. After the flue gas enters the box body 1, as the flue gas rises, the flue gas passes through the mesh plate 5 and contacts the filter material above the mesh plate 5, thereby improving the contact effect between the flue gas and the filter material. At the same time, the liquid inlet pipe 12 is connected to the desulfurization and denitrification liquid, and the desulfurization and denitrification liquid enters the spray pipe through the liquid inlet pipe 12 and is sprayed out through the nozzle 11, thereby desulfurizing and denitrifying the flue gas in the box body 1. After the desulfurization and denitrification liquid is sprayed through the nozzle 11, the desulfurization and denitrification are sprayed onto the filter material on the swing plate 6, so that the desulfurization and denitrification liquid can cooperate with the filter material to purify the flue gas;

[0092] When the smoke moves upward through the mesh plate 5, the smoke will contact the filter material at the bottom. In order to ensure the filtering effect of the filter material, the filter material on the mesh plate 5 needs to be cleaned, and the drive motor 38 is turned on. The second pulley 44 is driven to rotate by the output shaft of the drive motor 38. When the second pulley 44 rotates, it drives the first pulley 43 to rotate through the transmission belt 45. When the first pulley 43 rotates, it drives the drive rod 41 to rotate synchronously. When the drive rod 41 rotates, the second bevel gear 42 meshes with the first bevel gear 17 for transmission, and drives the first spiral feeding shaft 15 to work. When the first spiral feeding shaft 15 rotates, the filter material on the mesh plate 5 is transported to the cleaning cylinder;

[0093] The filter material enters the first guide plate 24 through the feed inlet 49, and is driven by the driving motor 38 to drive the second spiral feed shaft 20 to rotate. When the second spiral feed shaft 20 rotates, the second magnet 34 and the first magnet 33 are magnetically attracted to drive the sliding ring 22 to rotate. When the sliding ring 22 rotates, the first limit groove 27 and the first limit block 26 drive the first rotating ring 23 to rotate. When the first rotating ring 23 rotates, it drives the first guide plate 24 to rotate. The centrifugal force generated when the first guide plate 24 rotates drives the filter material to move, thereby reducing the speed at which the filter material moves downward, thereby reducing the moving speed of the filter material on the first guide plate 24, thereby increasing the cleaning time of the filter material and ensuring the cleaning effect.

[0094] After cleaning, the filter material falls on the inner bottom of the cleaning cylinder 18. At this time, the second spiral feeding shaft 20 is driven to rotate by the driving motor 38. When the second spiral feeding shaft 20 rotates, the filter material at the bottom of the cleaning cylinder 18 is transported, and the filter material is driven to move up in the installation cylinder 19. When the filter material moves up to a certain position in the installation cylinder 19, the filter material enters the feeding pipe 21. The filter material is transported to the box body 1 by the inclined feeding pipe 21 and falls on the upper surface of the swing plate 6 located at the uppermost layer. At this time, the cleaning and transportation of the filter material are completed, so as to facilitate the cleaning of the filter material and ensure the purification effect of the flue gas.

[0095] When the smoke intake of the smoke inlet pipe 2 increases, the spraying amount of the desulfurization and denitrification liquid also needs to be increased, and at the same time, the cleaning efficiency of the filter material should also be improved to ensure the desulfurization and denitrification effect of the flue gas; when the spraying amount of the desulfurization and denitrification liquid increases, the desulfurization and denitrification liquid is sprayed to the filter material on the uppermost swing plate 6, so that the weight of the filter material is further increased, and at this time, the swing plate 6 will be driven to further swing downward and squeeze the first hydraulic telescopic rod 9, and as the desulfurization and denitrification liquid and the filter material move downward, the other swing plates 6 below will be driven to swing downward, and at this time, the first hydraulic telescopic rod 9 will drive the second hydraulic telescopic rod 37 to work when it is squeezed;

[0096] The sliding ring 22 is driven downward by the second hydraulic telescopic rod 37; during the downward movement of the sliding ring 22, the distance between the second magnet 34 and the first magnet 33 increases, at which time the magnetic attraction effect of the second magnet 34 on the first magnet 33 decreases, and the driving effect of the second magnet 34 on the sliding ring 22 gradually decreases, thereby gradually reducing the rotation speed of the first guide plate 24, thereby reducing the influence of the first guide plate 24 on the downward movement speed of the filter material due to the rotation, thereby improving the feeding efficiency of the filter material through the first guide plate 24 and the first feed hole 25;

[0097] After the sliding ring 22 moves down to a certain position, the first limit block 26 of the first rotating ring 23 is disengaged from the first limit groove 27 on the sliding ring 22, and the second magnet 34 cannot indirectly drive the sliding ring 22 to rotate; when the sliding ring 22 continues to move down to a certain position, the second limit block 31 on the second rotating ring 28 is engaged with the second limit groove 32 on the sliding ring 22, and the third magnet 35 and the first magnet 33 are magnetically adsorbed, thereby driving the sliding ring 22 to rotate through the third magnet 35, and thereby driving the second guide plate 29 to rotate; as the sliding ring 22 moves down, the distance between the third magnet 35 and the first magnet 33 gradually decreases, thereby improving the driving effect of the third magnet 35 on the sliding ring 22, That is, the rotation speed of the sliding ring 22 is increased; when the filter material enters the second guide plate 29 through the first feed hole 25, the centrifugal force generated by the rotation of the second guide plate 29 can drive the filter material to move, thereby increasing the moving speed of the filter material, and the greater the rotation speed of the second guide plate 29, the faster the moving speed of the filter material on the second guide plate 29, thereby facilitating rapid conveying of the filter material, and at the same time, the cleaned filter material is conveyed to the box body 1 through the second spiral feeding shaft 20 and the feeding pipe 21, thereby improving the conveying efficiency of the filter material, thereby facilitating automatic adjustment of the conveying efficiency of the filter material according to the intake volume of the smoke, thereby ensuring the circulation speed of the filter material and the filtering effect of the filter material;

[0098] When the air intake volume decreases, the spraying volume of the desulfurization and denitrification liquid decreases, and the swing plate 6 swings upward. At this time, the first hydraulic telescopic rod 9 extends, and the second hydraulic telescopic rod 37 resets and drives the sliding ring 22 to move upward. During the upward movement of the sliding ring 22, the second limit block 31 can disengage from the second limit groove 32 to make the first limit block 26 on the first rotating ring 23 engage with the first limit groove 27. Subsequently, the second magnet 34 and the first magnet 33 can be adsorbed to drive the sliding ring 22 and the first rotating ring 23 to rotate, thereby reducing the circulation speed of the filter material and increasing the cleaning time of the filter material, further ensuring the cleaning effect.
