Description

Technical Field

[0001] This invention relates to the field of dust removal equipment, specifically a wet dust removal device for starch production workshops. Background Technology

[0002] Starch production workshops must install and use efficient dust removal systems. When starch dust reaches a certain concentration in the air and encounters open flames, static sparks, mechanical friction sparks, or high-temperature surfaces, it is extremely easy for a violent dust explosion to occur. Dust removal equipment is needed to control the dust concentration within a safe range.

[0003] Wet scrubbers are a crucial and commonly used dust removal device in starch production workshops, especially in environments with extremely high explosion-proof safety requirements. By bringing dust-laden gas into close contact with liquid, the dust particles are separated from the airflow and discharged with the water flow through the inertial collision, interception, and diffusion of water droplets. Existing wet scrubbers first use a fan to draw dust into the equipment and then spray it to remove dust. However, the continuous transport of starch dust generates heat, and the high-temperature starch gelatinizes upon contact with water, causing the starch separated by spraying to adhere to the bottom of the equipment and even block the pipes, making it difficult to discharge the starch-containing water.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-8 The diagram shows a wet dust removal device for a starch production workshop, comprising a housing 1 and an air inlet pipe 2 installed on the outside of the housing 1. A conveying pipe 3 is fixedly installed on the top of the housing 1, and an installation pipe 4 is fitted onto one end of the conveying pipe 3. Multiple branch pipes 5 are centrally symmetrically distributed on the outside of the installation pipe 4. A nozzle 6 is installed at the end of the branch pipe 5 away from the installation pipe 4. An exhaust fan box 7 is fixedly installed on the top of the housing 1. Dust-laden gas is conveyed into the housing 1 through the air inlet pipe 2. The conveying pipe 3 is connected to a drainage device, and water is conveyed into the installation pipe 4 through the conveying pipe 3 and then discharged from the nozzle 6 at the end of the branch pipe 5. This intercepts dust in the dust-laden gas, and the treated air is discharged through the exhaust fan box 7, thus achieving the treatment of dust in the dust-laden gas. The heat dissipation mechanism includes a vortex tube 8 disposed inside the equipment housing 1, which dissipates heat from the dust-laden gas. The mechanism also includes a mounting box 11 fixedly installed on the top of the equipment housing 1. One end of the vortex tube 8 is fixedly installed on the outside of the mounting box 11, and a connecting pipe 12 is fixedly installed on the end of the vortex tube 8 away from the mounting box 11. One end of the air inlet pipe 2 is installed inside the connecting pipe 12, allowing the dust-laden gas to enter the connecting pipe 12 through the air inlet pipe 2 and then enter the mounting box 11 along the vortex tube 8. An exhaust pipe is fixedly installed on the top of the mounting box 11. Multiple one-way exhaust valves 14, arranged symmetrically in a central configuration, are fixedly installed on the outer side of the exhaust pipe 13. Dust-laden gas inside the mounting box 11 can enter the exhaust pipe 13 and be divided into multiple streams by the one-way exhaust valves 14 before being discharged into the equipment housing 1. Water, submerged above the one-way exhaust valves 14, is first injected into the bottom of the equipment housing 1 through the nozzle 6, causing the one-way exhaust valves 14 to discharge the dust-laden gas into the water. This results in the dust-laden gas being discharged upwards as bubbles, facilitating the initial treatment of larger particles in the dust-laden gas before the finer particles are treated by the nozzle 6. A heat dissipation pipe 15 is fitted around the outside of the vortex tube 8, and the heat dissipation pipe 15 has a vortex structure. The two ends of the heat dissipation pipe 15 are respectively fixedly installed on the outside of the mounting box 11 and the docking pipe 12. The inner diameter of the heat dissipation pipe 15 is larger than the outer diameter of the vortex tube 8. A water inlet pipe 16 and a drain pipe 17 are respectively fixedly installed at the two ends of the heat dissipation pipe 15, and both the water inlet pipe 16 and the drain pipe 17 extend to the bottom of the equipment housing 1. Cold water is injected into the heat dissipation pipe 15 through the water inlet pipe 16, so that the flowing cold water carries away the heat of the dust-containing gas in the vortex tube 8, and then discharged from the drain pipe 17 to ensure that the dust-containing gas is discharged safely. The body is kept at a low temperature to prevent the starch in the dust-laden gas from gelatinizing when it comes into contact with water. It also allows for the reuse of the recovered heat. A drain valve 35 is fixedly installed at the bottom of the equipment shell 1 to discharge wastewater containing dust. The outer side of the heat dissipation pipe 15 is made of heat-insulating material. A support plate 36 is fixedly installed between the outer side of the connecting pipe 12 and the inner side of the equipment shell 1 to prevent the heat dissipation pipe 15 from heating the water at the bottom of the inner side of the equipment shell 1. The support plate 36 can provide auxiliary support for the connecting pipe 12 and the air inlet pipe 2 to ensure that the dust-laden gas enters the vortex tube 8 smoothly.

[0022] Example 2: Please refer to Figures 2-6This embodiment further illustrates Example 1. The spraying mechanism shown in the figure includes a toothed ring 9 sleeved on the outside of the mounting pipe 4. The toothed ring 9 enables the mounting pipe 4 to rotate continuously. The spraying mechanism also includes a mounting plate 19 fixedly mounted on the top of the equipment housing 1. A drive motor 20 is fixedly mounted on the top of the mounting plate 19. A first gear 21 is fixedly mounted on the output end of the drive motor 20. The first gear 21 meshes with the toothed ring 9. Multiple centrally symmetrically distributed insert teeth 22 are fixedly mounted on the inner side of the toothed ring 9. A sliding groove is provided on the outer side of the mounting pipe 4 for the insert teeth 22 to slide in a limited manner. The drive motor 20 can drive the first gear 21 to rotate, causing the first gear 21 to drive the toothed ring 9 to rotate. The toothed ring 9 drives the mounting pipe 4 to rotate through the insert teeth 22. The mounting pipe 4 can then cause the nozzles 6 on the multiple branch pipes 5 to perform circumferential motion, improving the spray surface of the dust-laden gas and achieving a uniform spraying effect. A positioning cylinder 23 is fixedly mounted on the top of the equipment housing 1, and the toothed ring 9 is rotatably mounted on the positioning cylinder 23. At the top of the mounting tube 3, the mounting tube 4 is installed inside the positioning cylinder 23. A collar 24 is rotatably installed at the bottom of the positioning cylinder 23. A support ring 25 is sleeved on the outside of the mounting tube 4. Multiple support rods 26 are fixedly installed between the support ring 25 and the collar 24 in a centrally symmetrical arrangement. Multiple positioning ribs 27 are fixedly installed on the outside of the mounting tube 4 in a centrally symmetrical arrangement. The inner side of the support ring 25 has a positioning groove corresponding to the positioning ribs 27, so that the mounting tube 4 can drive the support ring 25 to rotate synchronously by pressing against the inner side of the positioning groove through the positioning ribs 27. The support ring 25 drives the collar 24 to rotate along the bottom of the positioning cylinder 23 through the support rods 26, thereby providing auxiliary support for the outside of the mounting tube 4 and ensuring the smooth rotation of the mounting tube 4. A limit ring 37 is fixedly installed on the inner side of the collar 24, and a limit groove corresponding to the limit ring 37 is opened on the outside of the positioning cylinder 23, so that the collar 24 can drive the limit ring 37 to rotate along the inner side of the limit groove, providing support for the rotation of the collar 24.

[0023] Example 3: Please refer to Figures 2-8This embodiment further illustrates other embodiments. The cleaning structure shown in the figure includes two symmetrically fixed rotating rods 10 installed on the outside of the nozzle 6. The rotating rods 10 can cause the nozzle 6 to swing and spray. The cleaning structure also includes a sleeve 28 fixedly installed on the outside of the branch pipe 5. Both rotating rods 10 are rotatably installed on the outside of the sleeve 28. The end of the branch pipe 5 near the nozzle 6 has a spherical structure, and the inner side of the nozzle 6 has a spherical cavity corresponding to the spherical end of the branch pipe 5. A second gear 29 is fixedly installed on the end of the rotating rod 10 away from the nozzle 6. A rack plate 30 that meshes with the second gear 29 is provided on the outside of the rotating rod 10. A support arm 31 is fixedly installed between two adjacent rack plates 30. The support arm 31 is fixedly installed on the outside of the support ring 25. The mounting tube 4 faces downward. When moving, the nozzle 6 can be driven downward through the branch pipe 5. The nozzle 6 drives the second gear 29 on the outside of the rotating rod 10 to move along the surface of the rack plate 30, causing the rack plate 30 to drive the second gear 29 to rotate. The second gear 29 drives the nozzle 6 to swing towards the inner wall of the equipment shell 1 through the rotating rod 10, so that the nozzle 6 sprays the inner wall of the equipment shell 1, which facilitates the washing away of the starch adhering to the inner wall of the equipment shell 1. A slip ring 32 is fixedly installed on the outside of the mounting pipe 4. A sliding cavity for limiting the sliding of the slip ring 32 is opened on the inner side of the positioning cylinder 23. Multiple centrally symmetrically distributed sliding balls 33 are fixedly installed on the top of the slip ring 32. An arc-shaped groove for limiting the sliding of the sliding balls 33 is opened on the top of the inner side of the sliding cavity. A spring 34 that abuts against the bottom of the sliding cavity is fixedly installed on the bottom of the slip ring 32. When the mounting tube 4 rotates, it drives the slip ring 32 to rotate along the sliding cavity of the positioning cylinder 23. The slip ring 32 drives the slip ball 33 to move along the arc groove of the sliding cavity. When the slip ball 33 moves out of the arc groove, the reaction force of the top of the inner side of the sliding cavity on the slip ball 33 causes the slip ball 33 to push the slip ring 32 downward and compress the spring 34. The mounting tube 4 can then move along the inner side of the positioning cylinder 23, causing the mounting tube 4 to drive the rotating rod 10 on the nozzle 6 to move downward through the branch pipe 5. The second gear 29 can then move along the outer side of the rack plate 30. When the slip ball 33 is aligned with the arc groove again, the rebound force of the spring 34 pushes the slip ball 33 into the arc groove, and the mounting tube 4 can then return to its original position. The second gear 29 can then move along the outer side of the rack plate 30. Laterally, the nozzle 6 rotates with the installation pipe 4, allowing it to move in a circular motion while simultaneously oscillating back and forth. This improves the dust removal efficiency of the dust-laden gas and also washes the inner wall of the equipment casing 1. Three centrally symmetrical support bars 38 are fixedly installed on the outer side of the collar 24. An arc-shaped scraper 39 is fixedly installed at the end of the support bar 38 away from the collar 24, and the outer side of the arc-shaped scraper 39 contacts the inner side of the equipment casing 1. The support ring 25 can drive the collar 24 to rotate via the support rod 26, causing the collar 24 to drive the support bars 38 to rotate. The support bars 38 drive the arc-shaped scraper 39 to move in a circular motion along the inner side of the equipment casing 1, facilitating the spraying of the inner side of the equipment casing 1 by the nozzle 6, and allowing the arc-shaped scraper 39 to scrape off the adhering starch.A ball joint 40 is rotatably mounted on the top of the support bar 38, and an annular groove is provided on the top of the equipment housing 1 for the ball joint 40 to slide within a limited range. This allows the support bar 38 to drive the ball joint 40 to move in a circular motion along the inner side of the annular groove. The ball joint 40 provides auxiliary support to the support bar 38, ensuring the smooth rotation of the support bar 38. A support frame 18 is fixedly installed between the two rack plates 30 to prevent the rack plates 30 from tilting.

[0024] Working principle: First, the operator opens the delivery pipe 3, injects water into the installation pipe 4 through the delivery pipe 3, and discharges it downwards from the nozzle 6 through the branch pipe 5, filling the equipment casing 1 with water until it covers the one-way exhaust valve 14. Then, the operator connects the pipe for conveying dust-laden gas to the inlet pipe 2, allowing the dust-laden gas to flow into the vortex tube 8 through the inlet pipe 2. The operator also connects the pipe for conveying cold water to the water inlet pipe 16, allowing the cold water to move along the inner side of the heat dissipation pipe 15, carrying away the heat from the dust-laden gas in the vortex tube 8. The heated water can be discharged from the drain pipe 17 for easy recycling. The cooled dust-laden gas is divided into multiple airflows through the exhaust pipe 13 and enters multiple one-way exhaust valves 14. The multiple one-way exhaust valves 14 then distribute the dust-laden gas... Multiple airflows are discharged into the water, causing the dust-laden gas to rise as bubbles. The water inside the equipment casing 1 adsorbs larger particles from the dust-laden gas, which are then sprayed through nozzles 6 to atomize the finer particles. Simultaneously, the drive motor 20 rotates the first gear 21, which in turn rotates the gear ring 9. The gear ring 9, through the insert teeth 22, rotates the mounting tube 4. The mounting tube 4 causes the nozzles 6 on multiple branch pipes 5 to move in a circular motion, achieving a uniform spraying effect. Simultaneously, the mounting tube 4 causes the slip ring 32 to rotate within the sliding cavity of the positioning cylinder 23. The slip ring 32 causes the sliding ball 33 to move along the arc-shaped groove within the sliding cavity. When the sliding ball 33 moves out of the arc-shaped groove, the reaction force from the top of the inner side of the sliding cavity pushes the slip ring 32 downwards. The movement compresses the spring 34, causing the slip ring 32 to move the mounting tube 4 downwards along the inner side of the positioning cylinder 23. This causes the mounting tube 4 to move the nozzle 6 downwards via the branch pipe 5. The nozzle 6 then moves the second gear 29 on the outer side of the rotating rod 10 along the surface of the rack plate 30, causing the rack plate 30 to rotate the second gear 29. The second gear 29 then drives the nozzle 6 to swing towards the inner wall of the equipment housing 1 via the rotating rod 10, spraying the nozzle 6 onto the inner wall of the equipment housing 1 to soften the starch adhering to it. Subsequently, when the slip ball 33 aligns with the arc groove again, the spring 34's rebound force pushes the slip ball 33 into the arc groove. The slip ring 32 then pulls the mounting tube 4 upwards to reset, causing the nozzle 6 to move the second gear 29 on the rotating rod 10 downwards. Wheel 29 returns to its original position along the outer side of rack plate 30, allowing nozzle 6 to swing back. Thus, as mounting pipe 4 rotates, nozzle 6 can perform both circular and reciprocating oscillations. Simultaneously, mounting pipe 4, via positioning rib 27, abuts against the inner side of positioning groove, causing support ring 25 to rotate synchronously. Support ring 25, via support rod 26, drives collar 24 to rotate along the bottom of positioning cylinder 23, causing collar 24 to drive three support bars 38 to rotate. Support bars 38 drive arc-shaped scraper 39 to perform circular motion along the inner side of equipment casing 1, allowing arc-shaped scraper 39, in conjunction with the reciprocating nozzle 6, to clean the inner wall of equipment casing 1, ensuring starch can promptly enter the water at the bottom of equipment casing 1. Finally, the treated dust-laden gas is discharged through exhaust fan 7.Workers can also drain the starch-containing water through drain valve 35, thus achieving safe dust removal and improving dust removal efficiency.
