Environment-friendly dust removal equipment for cement processing

Abstract

This invention relates to the field of dust removal equipment technology and discloses an environmentally friendly dust removal device for cement processing, including a main pipe assembly. A liquid storage assembly is fixedly installed on the outside of the main pipe assembly, and a gas guiding assembly is installed at the bottom inside the main pipe assembly. A sealing assembly is fixedly installed on the top of the gas guiding assembly. This environmentally friendly dust removal device for cement processing has a gas guiding component installed inside the bottom of the main pipe assembly. The gas guiding component has a frustum-shaped hollow cavity that runs through it from top to bottom. A liquid accumulation cavity is also opened on the outside of the cavity inside the gas guiding component. In this way, the gas containing dust enters the bottom of the gas guiding component and flows upward. Due to the design of the frustum-shaped hollow cavity in the center, the flow diameter of the gas becomes smaller when it passes through it, thereby increasing the flow velocity. After the gas breaks through the top of the gas guiding component, the flow diameter suddenly becomes larger, thereby causing the flow velocity to suddenly decrease.

Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, specifically to an environmentally friendly dust removal device for cement processing. Background Technology

[0002] The cement industry is a crucial raw material industry for my country's national economy, but it is also a high-energy-consuming and high-emission polluting industry. Throughout the entire cement production process, including raw material crushing, raw meal grinding, clinker calcination, cement grinding, and finished product packaging, a large amount of dust-laden waste gas is generated. The dust produced during cement processing is characterized by a large particle size range, easy dispersion, and strong abrasiveness. Therefore, dust removal equipment is necessary in existing cement production processes, not only to protect the environmental safety of the production workshop but also to prevent the emission of large amounts of dust-laden gas and environmental pollution. However, existing dust removal equipment still has some problems in its use, as follows: Existing dust removal equipment mainly uses dry or wet dust collection methods, with spray towers being a commonly used example. However, while existing spray towers can remove dust, they primarily rely on a packing layer to slow down the gas flow and increase its contact with the sprayed water mist, including contact time and area. This method requires frequent maintenance of the packing layer; otherwise, the dust and liquid will come into contact and form a poorly flowing sludge, which will severely block the gas flow channels inside the packing layer. This not only greatly increases the flow resistance of the gas but also prevents the subsequent gas from fully mixing with the sprayed liquid. Furthermore, if the packing layer dries out, it cannot be cleaned and must be replaced entirely, significantly increasing the operating cost of the equipment. Therefore, we propose an environmentally friendly dust removal device for cement processing. Summary of the Invention

A drain groove is evenly formed on the annular cover plate, and a guide ramp is fixedly installed on the lower surface of the annular cover plate. The annular cover plate is fixedly installed at the top of the liquid accumulation cavity at the top of the air guide component.

[0009] In a preferred embodiment, the driven assembly includes a support crossbar, a wind-breaking cone is fixedly installed at the bottom center of the support crossbar, an impeller is rotatably installed at the upper center of the support crossbar, a transmission rod is fixedly installed at the top of the impeller, a first gear is fixedly installed at the top of the transmission rod, a power regulator is installed on the support crossbar, the power regulator can automatically adjust the power according to the wind force, a water pump connected to the bottom of the water guide pipe is electrically connected to the power regulator, a flow guide groove is formed on the lower surface of the impeller, and the first gear is meshed with the cleaning assembly.

[0010] In a preferred embodiment, the cleaning assembly includes a support rod, a support block fixedly mounted at the top end of the support rod, support arms fixedly mounted at both ends of the support block, a clamp provided at the end of the support arm, a drive gear ring rotatably mounted inside the clamp, a plurality of base blocks uniformly fixedly mounted in a ring on the upper surface of the drive gear ring, a vertical scraper fixedly mounted on the side of the base block, a lower scraper fixedly mounted on the lower side of the vertical scraper, an upper scraper fixedly mounted at the top end of the base block, and a rotating rod rotatably mounted inside the support block, with second gears fixedly mounted at both ends of the rotating rod.

[0011] In a preferred embodiment, the bottom end of the support rod is fixedly installed on the upper surface of the inner guide ring. The drive gear ring meshes with the outer second gear, and the inner second gear meshes with the first gear. The size of the second gears on both sides can be changed to different sizes as needed. The lower scraper is connected to the vertical scraper via an L-shaped connection. The vertical scraper slides against the inside of the main pipe assembly. The lower scraper slides against the upper surface of the annular cover plate. The upper scraper slides against the lower surface of the water film forming filter assembly.

[0012] In a preferred embodiment, the water film forming filter assembly includes an outer frame, a support foot fixedly installed at the bottom edge of the outer frame, a filler filter layer installed inside the outer frame, and a water supply head fixedly installed at the top center of the outer frame.

[0013] In a preferred embodiment, the outer frame has a through-hole, the support leg is fixedly connected to the inside of the main pipe assembly, the filling filter layer is made of a mesh fabric woven from hydrophilic fibers, and the filling filter layer and the outer frame are spaced apart, with capillary water-conducting material filling the gaps, the top of the water supply head is sealed and fixedly connected to the water pipe, and multiple water outlets are opened on the bottom side.

[0014] The present invention has the following beneficial effects: 1. This environmentally friendly dust removal equipment for cement processing features an air guide installed inside the bottom of the main pipe assembly. The air guide has a frustum-shaped hollow cavity running vertically through it, and a liquid accumulation chamber is located on the outer side of the cavity within the air guide. When dust-laden gas enters the bottom of the air guide, it flows upwards. The frustum-shaped hollow cavity in the center causes the gas flow diameter to narrow as it passes through, increasing the flow velocity. However, after the gas passes through the top of the air guide, the flow diameter suddenly widens, causing the flow velocity to drop sharply. Heavier dust particles in the gas then diffuse and move towards the inner wall of the main pipe assembly. Furthermore, the air guide contains guide ribs and a driven component, which increase the violent rotation of the gas as it flows upwards. Upon reaching the top, the strong centrifugal force further enhances the separation of dust particles, demonstrating the equipment's effective dust removal.

[0015] 2. This environmentally friendly dust removal equipment for cement processing utilizes a driven component that allows the airflow to impact the impeller as it flows upward, causing it to rotate. This upward flow of gas is combined with increased rotation, further enhanced by the design of guide ribs. The first gear above rotates synchronously with the impeller, driving the rotation of the cleaning component structure. A sealing component is also installed on the air guide component, ensuring the recovery of dust mixed with the sprayed liquid and preventing negative pressure suction from the continuously supplied airflow. The rotation of the cleaning component scrapes and cleans the sealing component, main pipe component, and water film filter component as a whole. This achieves effective dust removal without affecting the internal gas flow channel, greatly improving the ease of use, reducing maintenance frequency, and enhancing the overall performance.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The environmentally friendly dust removal equipment for cement processing involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-2 An environmentally friendly dust removal device for cement processing includes a main pipe assembly 1, a liquid storage assembly 2 fixedly installed on the outside of the main pipe assembly 1, an air guiding assembly 3 installed at the bottom inside the main pipe assembly 1, a cover assembly 4 fixedly installed above the air guiding assembly 3, a driven assembly 5 installed inside the air guiding assembly 3, a cleaning assembly 6 fixedly installed on the cover assembly 4, a water film forming filter assembly 7 fixedly installed at the top inside the main pipe assembly 1, a water guide pipe 8 fixedly installed at the top of the water film forming filter assembly 7, and a water pump installed inside the liquid storage assembly 2, with the water pump connected to one end of the water guide pipe 8. Compared with the prior art, this application features a gas guide 31 installed inside the bottom of the main pipe assembly 1. The gas guide 31 has a frustum-shaped hollow cavity extending vertically through it, and a liquid accumulation chamber is also formed on the outer side of the cavity within the gas guide 31. When dust-laden gas enters the bottom of the gas guide 31, it flows upwards. Due to the design of the central frustum-shaped hollow cavity, the flow diameter decreases as the gas passes through it, increasing the flow velocity. However, after the gas passes through the top of the gas guide 31, the flow diameter suddenly increases, causing a sudden decrease in flow velocity. This causes the relatively heavier dust particles in the gas to diffuse and move towards the inner wall of the main pipe assembly 1 in large quantities. Furthermore, the gas guide 31 is equipped with guide ribs 35 and a driven component 5, which increases the violent rotation of the gas during its upward flow. Upon reaching the top, the strong centrifugal force further enhances the separation of dust particles in the gas, demonstrating… The dust removal effect of the equipment is enhanced by the driven component 5, which allows the airflow to impact the impeller 53 and cause it to rotate as it flows upward. This increases the rotational state while the gas flows upward, and the design of the guide ribs 35 further enhances the rotation. The first gear 55 above rotates synchronously under the rotation of the impeller 53, which drives the rotation of the cleaning component 6. A sealing component 4 is also provided on the air guide component 3, which ensures the recovery and treatment of dust mixed in with the sprayed liquid and avoids the negative pressure suction caused by the continuously supplied airflow. The rotation of the cleaning component 6 will achieve the overall scraping and cleaning of the sealing component 4, the main pipe component 1, and the water film forming filter component 7. This can not affect the internal gas flow channel and achieve effective dust removal, greatly improving the ease of use of the equipment, reducing the maintenance frequency, and improving the performance.

[0020] Please see Figures 1-5 An environmentally friendly dust removal device for cement processing includes a main pipe assembly 1 and a liquid storage assembly 2. The main pipe assembly 1 includes a pipe body 101, with discharge grooves 102 at both the upper and lower ends of the pipe body 101. A mounting hole 103 is provided at the top end of the pipe body 101, and a water guide pipe 8 is connected through the mounting hole 103. The liquid storage assembly 2 includes a liquid storage ring cavity 21, with a ring cavity inside the liquid storage ring cavity 21. The upper and lower ends of the inner ring of the liquid storage ring cavity 21 are provided with inlet grooves 22, which are at the same height and corresponding to the discharge grooves 102. An isolation ring 23 is located within the height range between the upper and lower inlet grooves 22, dividing the ring cavity inside the liquid storage ring cavity 21 into a primary collection cavity and a secondary collection cavity. The primary collection cavity is connected to the interior of the air guide assembly 3, and the secondary collection cavity is connected to the interior of the main pipe assembly 1 at the top of the water film forming filter assembly 7. In this embodiment, it should be noted that during use, the gas passing through the air guide component 3 reaches the main pipe component 1 and, under the effect of diffusion, separates the internal particulate impurities. The gas then remains on the sealing component 4. This gas drives the driven component 5 to rotate, which in turn drives the cleaning component 6 to rotate, scraping away dust particles. The water flowing continuously in the water film forming filter component 7 also flows downwards along the inner wall of the main pipe component 1. This causes the water to mix with dust particles and flow into the air guide component 3 for collection. Above the water film forming filter component 7, the filtered gas carries some water vapor upwards as it flows upwards. This water vapor then gradually flows downwards after contacting the inner wall of the main pipe component 1, eventually entering the secondary collection chamber for collection. This prevents the relatively clean water collected in the secondary collection chamber from mixing with the dirty water below, ensuring effective collection.

[0021] Please see Figures 1-6 An environmentally friendly dust removal device for cement processing includes an air guiding component 3, which includes an air guiding element 31. An overflow groove 32 is provided on the air guiding element 31. A connecting pipe 33 is fixedly installed at the bottom end of the air guiding element 31. A sewage pipe 34 is fixedly installed outside the connecting pipe 33 at the bottom end of the air guiding element 31. A flow guiding rib 35 is fixedly installed inside the air guiding element 31. A filter screen 36 is fixedly installed inside the air guiding element 31. A flow guiding partition ring 37 is fixedly installed above the filter screen 36. In this embodiment, it should be noted that the air guide 31 has a frustum-shaped hollow cavity extending through its upper and lower ends, and a liquid accumulation cavity is also formed on the outer side of the cavity inside the air guide 31. An overflow groove 32 extends through the liquid accumulation cavity. The bottom end of the connecting pipe 33 has an internal thread. The drain pipe 34 is connected to the liquid accumulation cavity. Guide ribs 35 are uniformly and annularly fixed to the inner wall of the frustum-shaped hollow cavity. A filter screen 36 and a flow-guiding separator ring 37 are fixedly installed inside the liquid accumulation cavity. The top of the flow-guiding separator ring 37 is higher than the position of the inlet groove 22 and abuts against the bottom end of the capping assembly 4. The bottom end is lower than the height of the inlet groove 22 and spaced apart from the inner wall of the liquid accumulation cavity. This allows the water containing dust particles collected above to flow into the liquid accumulation cavity of the air guide 31 for collection, and then be filtered by the filter screen 36 to obtain relatively clean water. Water overflows into the primary collection chamber of the liquid storage ring cavity 21 for storage, facilitating subsequent recycling. The internal frustum-shaped hollow cavity accelerates the airflow passing through it and rotates under the guidance of the guide ribs 35. This rotation is further enhanced by the drive component 5. When the gas reaches the top of the gas guide component 3, a diffusion effect occurs, causing dust particles to separate onto the inner wall of the main pipe component 1 under centrifugal force. The continuously flowing water above adsorbs the dust particles and they flow downwards to the liquid accumulation chamber inside the gas guide component 3 for collection. The design of the guide ribs 35 also causes a small vibration when the airflow impacts the gas guide component 31, which helps the particulate impurities in the liquid accumulation chamber to settle and separate from the water, improving the cleanliness of the overflowing water.

[0022] Please see Figures 1-6 An environmentally friendly dust removal device for cement processing includes a cover assembly 4, which includes an annular cover plate 41. An inner guide ring 42 and an outer guide ring 43 are fixedly installed on the upper inner ring and outer ring of the annular cover plate 41, respectively. A sewage discharge groove 44 is evenly opened on the annular cover plate 41, and a guide inclined plate 45 is fixedly installed on the lower surface of the annular cover plate 41. In this embodiment, it should be noted that the annular cover plate 41 is fixedly installed at the top of the liquid accumulation cavity at the top of the air guide 31. The outer and inner sides of the cross-sections of the inner guide ring 42 and the outer guide ring 43 are respectively inclined. The guide plate 45 is fixedly installed at the bottom of the sewage trough 44. In this way, after the water flow above carries the adsorbed dust particles to the surface of the annular cover plate 41, they will flow through the sewage trough 44 to the guide plate 45 under the rotation and scraping action of the cleaning component 6, and then enter the liquid accumulation cavity inside the air guide component 3 for collection. At the same time, the guide plate 45 can also prevent the low air pressure generated by the high-speed airflow above the annular cover plate 41 from creating a pressure difference with the high air pressure below, so that the sewage or dust particles below are drawn back into the main pipe component 1 in reverse flow, thus ensuring the dust removal effect.

[0023] Please see Figures 1-7 An environmentally friendly dust removal device for cement processing includes a driven component 5. The driven component 5 includes a support crossbar 51. A wind-breaking cone 52 is fixedly installed at the bottom center of the support crossbar 51. An impeller 53 is rotatably installed at the top center of the support crossbar 51. A transmission rod 54 is fixedly installed at the top of the impeller 53. A first gear 55 is fixedly installed at the top of the transmission rod 54. In this embodiment, it should be noted that a power regulator is installed on the support crossbar 51. The power regulator can automatically adjust the power according to the wind force. The water pump connected to the bottom end of the water guide pipe 8 is electrically connected to the power regulator. A flow guide groove is opened on the lower surface of the impeller 53. The first gear 55 is meshed with the cleaning component 6. In this way, the power of the water pump can be automatically adjusted according to the wind force, thereby ensuring that the water output at the top is automatically adjusted. The flow guide groove at the bottom of the impeller 53 can guide the airflow to more effectively impact the blade surface, reduce the lateral component of the airflow impact and the lateral flow and spillage of the airflow rotation on the surface of the impeller 53, and improve the efficiency of converting the kinetic energy of the airflow into rotational kinetic energy.

[0024] Please see Figures 2-8 An environmentally friendly dust removal device for cement processing includes a cleaning component 6. The cleaning component 6 includes a support rod 61. A support block 62 is fixedly installed at the top of the support rod 61. Support arms 63 are fixedly installed at both ends of the support block 62. A clamp is provided at the end of the support arm 63. A drive gear ring 64 is rotatably installed inside the clamp. Multiple base blocks 65 are evenly fixedly installed in a ring on the upper surface of the drive gear ring 64. A vertical scraper 66 is fixedly installed on the side of the base block 65. A lower scraper 67 is fixedly installed on the lower side of the vertical scraper 66. An upper scraper 68 is fixedly installed at the top of the base block 65. A rotating rod 69 is rotatably installed inside the support block 62. A second gear 610 is fixedly installed at both ends of the rotating rod 69. In this embodiment, it should be noted that the bottom end of the support rod 61 is fixedly installed on the upper surface of the inner guide ring 42. The drive gear ring 64 meshes with the outer second gear 610, and the inner second gear 610 meshes with the first gear 55. The size of the second gears 610 on both sides can be changed to different sizes as needed. The lower scraper rod 67 is connected to the vertical scraper rod 66 through an L-shaped connection. The vertical scraper rod 66 is slidably disposed inside the main pipe assembly 1. The lower scraper rod 67 is slidably disposed on the upper surface of the annular cover plate 41. The upper scraper rod 68 is disposed on the water film to form the filter assembly 7. The lower surface is slidably set, so that the rotation of the first gear 55 can drive the second gear 610 to rotate, which in turn drives the drive gear ring 64 to rotate, which in turn drives the base block 65 connected to it to rotate. This enables the upper scraper 68 and the lower scraper 67 to rotate synchronously, cleaning the surfaces of the water film forming filter assembly 7 and the sealing assembly 4. At the same time, the vertical scraper 66 will also scrape the inner surface of the main pipe assembly 1, thereby achieving synchronous self-cleaning of the overall internal structure, which greatly reduces the maintenance frequency of the equipment and improves the efficiency and filtration effect of the equipment.

[0025] Please see Figures 2-9 An environmentally friendly dust removal device for cement processing includes a water film forming filter assembly 7. The water film forming filter assembly 7 includes an outer frame 71. A support leg 72 is fixedly installed on the bottom edge of the outer frame 71. A filler filter layer 73 is installed inside the outer frame 71. A water supply head 74 is fixedly installed at the top center of the outer frame 71. In this embodiment, it should be noted that the outer frame 71 has a through-hole, the support leg 72 is fixedly connected to the inside of the main pipe assembly 1, the filling filter layer 73 is made of a mesh fabric woven from hydrophilic fibers, and the filling filter layer 73 is spaced apart from the outer frame 71, with capillary water-conducting material filling the gaps. The top of the water supply head 74 is sealed and fixedly connected to the water guide pipe 8, and multiple water outlets are opened on the bottom side. In this way, the water flow delivered by the water pump enters the water supply head 74 and is discharged from the water outlets to the surface of the outer frame 71. The filling filter layer 73 can make the water flow form a water film during the flow process, so that the filtered dust particles can be discharged downward in time by the flow, avoiding accumulation at the vent holes and causing blockage, thus ensuring the filtration effect and sustainable use of the entire device.

[0026] The working principle is as follows: The external duct is sealed and connected to the connecting pipe 33. After the gas enters the frustum-shaped hollow cavity of the air guide 31, the flow velocity gradually increases due to the structural design, driving the impeller 53 to rotate and causing the airflow to rotate. Under the guidance of the guide ribs 35, the airflow rotates more fully and effectively. After passing through the air guide assembly 3 and reaching the main pipe assembly 1, the rotating airflow generates a diffusion effect, causing dust particles to diffuse and separate onto the inner wall of the main pipe assembly 1. Simultaneously, the water pump connected to the water guide pipe 8 pumps water for dust removal into the water supply head 74, which flows along the surface of the outer frame 71 and penetrates into the internal filler filter layer 73 to form a water film. Excess water flows downwards along the inner wall of the main pipe assembly 1, thus... The dust particles separated by diffusion are adsorbed and flow downwards onto the upper surface of the annular cover plate 41, and finally flow into the liquid collection chamber of the air guide 31 for collection. Meanwhile, the impeller 53 drives the first gear 55 to rotate, which in turn drives the second gear 610 to rotate, thereby driving the drive gear ring 64 to rotate. The drive gear ring 64 drives the vertical scraper 66, the lower scraper 67, and the upper scraper 68 to rotate synchronously, thereby scraping and cleaning the inner wall of the main pipe assembly 1, the upper surface of the annular cover plate 41, and the lower surface of the outer frame 71. The dust-removed gas passes through the water film to form the filter assembly 7 and is discharged from the top. Some of the clean water vapor carried out in this process can subsequently flow up and down along the inner wall of the main pipe assembly 1 to the secondary collection chamber of the liquid storage ring chamber 21 for collection. In the later stage, only the stains in the liquid collection chamber need to be cleaned periodically.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
