Description

Technical Field

[0001] This utility model relates to the technical field of dust removal and purification equipment, specifically to an integrated device for dust and nitrogen removal and dry desulfurization using ceramic filter tubes. Background Technology

[0002] Ceramic filter tubes are characterized by high temperature resistance, corrosion resistance, high strength, and good filtration performance. In some integrated denitrification and desulfurization processes, ceramic filter tubes can be used in combination with denitrification and desulfurization agents. By loading specific catalysts or adsorbents onto the surface of the filter tube, when flue gas passes through the filter tube, not only is dust filtered out, but sulfur dioxide and nitrogen oxides can also react chemically with the substances on the surface of the filter tube and be adsorbed or converted into harmless substances, thereby achieving synergistic treatment of dust removal, denitrification, and desulfurization.

[0003] The dust and solids collected by the flue gas filtration on the surface of the ceramic filter tube are usually cleaned by pulse backflushing or other methods to remove the dust and solids adhering to the ceramic tube and fall into the ash hopper. The dust and solids in the ash hopper are then collected and treated in a unified manner.

[0004] Existing ash hoppers are typically funnel-shaped. When too much ash accumulates, the surface of the ash pile gradually flattens, reducing the component of gravity acting on the dust at the top of the pile along the surface. This makes it difficult for the dust to slide down the ash hopper wall. Furthermore, at the ash discharge port, the increased pressure and friction between dust particles can easily form an arched structure. This arched structure prevents the dust above from falling further, making cleaning more difficult and increasing equipment maintenance costs. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an integrated device for dust and nitrogen removal and dry desulfurization using ceramic filter tubes, which can effectively solve the problem of excessive dust accumulation in the ash hopper and its inability to be discharged smoothly in the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an integrated device for dust and nitrogen removal and dry desulfurization using ceramic filter tubes, comprising a shell body, an ash hopper connected to the bottom end of the shell body, the ash hopper being funnel-shaped, a vibrating plate rotatably connected to the inner side wall surface of the ash hopper, a vibration mechanism provided on one side of the vibrating plate, the vibration mechanism including a moving rod, one end of the moving rod abutting against the vibrating plate, a discharge hopper connected to the bottom end of the ash hopper, a material distribution mechanism provided inside the discharge hopper, the material distribution mechanism including a stirring shaft and a material distribution plate, the two ends of the stirring shaft and the material distribution plate being rotatably connected to the side wall of the discharge hopper respectively.

[0008] Furthermore, the end of the moving rod away from the vibrating plate is slidably connected to a limiting seat, and a support plate is fixedly connected to the bottom end of the limiting seat. One side of the support plate is fixedly connected to the ash hopper.

[0009] Furthermore, a limiting plate is fixedly connected to the outer wall of the moving rod, and a spring is provided between the limiting plate and the limiting seat.

[0010] Furthermore, a connecting shaft is provided at the top of the moving rod, the bottom end of the connecting shaft is fixedly connected to the moving rod, a first gear is rotatably connected to the outer wall of the connecting shaft, the axis of the first gear is separated from the axis of the connecting shaft, a second gear is rotatably connected to one side of the first gear, a first motor is provided at the top of the second gear, and the output end of the first motor is fixedly connected to the axis of the second gear.

[0011] Furthermore, the outer wall of the stirring shaft is provided with rake teeth, which are arranged sequentially along the central axis of the stirring shaft.

[0012] Furthermore, the material distribution plates are fixedly connected at one end to each other via a rotating shaft, and the material distribution plates are arranged in a ring array around the central axis of the rotating shaft.

[0013] Furthermore, the stirring shaft and the rotating shaft are respectively connected to the side wall of the discharge hopper at one end on the same side. The stirring shaft and the rotating shaft are respectively fixedly connected to a first transmission wheel and a second transmission wheel, and the first transmission wheel and the second transmission wheel are connected by a transmission belt.

[0014] Furthermore, a second motor is provided on one side of the second transmission wheel, and the output end of the second motor is fixedly connected to the shaft center of the second transmission wheel. Beneficial effects

[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0016] 1. By installing a vibration mechanism next to the side wall of the ash hopper, the vibration force is transmitted to the inside of the ash hopper by repeatedly striking the vibrating plate through the output end of the vibration mechanism. This increases the fluidity of the dust, reduces the friction between dust particles, and the vibration generated by the striking gives the dust particles on the surface of the ash hopper side wall energy, which overcomes the adhesion between them and the side wall, making it easier for the dust to fall off the side wall, thus making the ash cleaning work smoother.

[0017] Second, the second motor simultaneously drives the mixing shaft and the distribution plate to rotate. When the mixing shaft rotates, the rake teeth distributed on its outer wall can repeatedly stir the dust accumulated around it, thereby breaking the mutual support force between the dust particles in the arched structure at the ash discharge port, allowing the accumulated ash above to fall smoothly. Then, the rotation of the distribution plate clears the blockage, allowing the accumulated ash to be discharged more smoothly, which is convenient for operators to clean the ash and saves the daily maintenance cost of the equipment.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] See attached document Figure 1-7 An integrated device for dust and nitrogen removal and dry desulfurization using ceramic filter tubes includes an outer shell 1. A hopper 2 is connected to the bottom of the outer shell 1. The hopper 2 is funnel-shaped. A vibrating plate 6 is rotatably connected to the inner wall surface of the hopper 2. A vibration mechanism 4 is provided on one side of the vibrating plate 6. The vibration mechanism 4 includes a moving rod 402. One end of the moving rod 402 abuts against the vibrating plate 6. A discharge hopper 3 is connected to the bottom of the hopper 2. A material distribution mechanism 5 is provided inside the discharge hopper 3. The material distribution mechanism 5 includes a stirring shaft 501 and a material distribution plate 502. The two ends of the stirring shaft 501 and the material distribution plate 502 are rotatably connected to the side wall of the discharge hopper 3, respectively.

[0030] The end of the moving rod 402 away from the vibrating plate 6 is slidably connected to the limiting seat 403. There are two sets of limiting seats 403. The moving rod 402 can move linearly along the limiting seats 403 at both ends. The bottom end of the limiting seat 403 is fixedly connected to the support plate 401. One side of the support plate 401 is fixedly connected to the ash hopper 2. Through the fixed connection between the support plate 401 and the side wall of the ash hopper 2, effective support is provided for the entire vibration mechanism 4.

[0031] A limiting plate 407 is fixedly connected to the outer wall of the moving rod 402. A spring 404 is provided between the limiting plate 407 and the limiting seat 403. A connecting shaft 408 is provided at the top of the moving rod 402, and the bottom end of the connecting shaft 408 is fixedly connected to the moving rod 402. A first gear 405 is rotatably connected to the outer wall of the top of the connecting shaft 408. The axis of the first gear 405 is offset from the axis of the connecting shaft 408. A second gear 406 is rotatably connected to one side of the first gear 405. Under the elastic compression of the limiting plate 407 by the spring 404, the moving rod 402 drives the first gear 405 sleeved on the connecting shaft 408 to always mesh with the second gear 406. When the second gear 406 rotates, the first gear 405 begins to rotate around the connecting shaft 408. Because the axis of the connecting shaft 408 is offset from the axis of the first gear 405, during the rotation of the first gear 405, the distance from the meshing point of the first gear 405 and the second gear 406 to the connecting shaft 406 is limited. The distance of the connecting shaft 408 is constantly changing, which causes the connecting shaft 408 to drive the moving rod 402 to perform a cyclic linear motion along the limiting seat 403. During the reciprocating motion of the moving rod 402, one end of it starts to continuously strike the vibrating plate 6. Under the transmission of the vibration force of the vibrating plate 6, the fluidity of the dust is enhanced and the friction between the dust particles is reduced. The vibration generated by the striking gives the dust particles on the side wall surface of the ash hopper 2 energy, overcomes the adhesion between them and the side wall, and makes it easier for the dust to fall off the side wall. Then, under the action of gravity, the dust moves towards the discharge hopper 3. The top of the second gear 406 is equipped with a first motor 409. The output end of the first motor 409 is fixedly connected to the shaft of the second gear 406. By starting the first motor 409, the output end of the first motor 409 drives the second gear 406 to rotate. The rotation of the second gear 406 drives the rotation of the first gear 405, thereby realizing the smooth operation of the vibration mechanism 4.

[0032] The outer wall of the stirring shaft 501 is provided with rake teeth, which are arranged sequentially along the central axis of the stirring shaft 501. When the stirring shaft 501 rotates, the rake teeth distributed on its outer wall can repeatedly stir the dust accumulated around it, thereby destroying the mutual support force between dust particles in the arched structure at the ash discharge port, so that the dust above can continue to fall.

[0033] The material distribution plates 502 are fixedly connected at one end to each other by a rotating shaft 507. The material distribution plates 502 are arranged in a ring array around the central axis of the rotating shaft 507. The rotation of the material distribution plates 502 can also play a certain role in unblocking the ash discharge port, so that the ash can be discharged more smoothly.

[0034] The stirring shaft 501 and the rotating shaft 507 are respectively connected to the side wall of the discharge hopper 3 at one end on the same side. The stirring shaft 501 and the rotating shaft 507 are respectively fixedly connected to the first transmission wheel 503 and the second transmission wheel 505. The first transmission wheel 503 and the second transmission wheel 505 are connected by a transmission belt 504. A second motor 506 is provided on one side of the second transmission wheel 505. The output end of the second motor 506 is fixedly connected to the shaft center of the second transmission wheel 505. When the second motor 506 is started, the output end of the second motor 506 drives the second transmission wheel 505 to rotate. The rotation of the second transmission wheel 505 drives the rotating shaft 507 to rotate. The rotation of the rotating shaft 507 realizes the rotation of the material distribution plate 502. While the second transmission wheel 505 is rotating, it drives the first transmission wheel 503 to rotate through the transmission belt 504. The rotation of the first transmission wheel 503 drives the stirring shaft 501 to rotate.

[0035] Working principle:

[0036] When the dust hopper 2 accumulates too much dust and needs to be cleaned, the first motor 409 is started first. The output of the first motor 409 drives the second gear 406 to rotate. The rotation of the second gear 406 drives the first gear 405 to rotate. Under the elastic compression of the spring 404 against the limiting plate 407, the first gear 405 is always meshed with the second gear 406. Because the connecting shaft 408 is offset from the axis of the first gear 405, the distance from the meshing point of the first gear 405 and the second gear 406 to the connecting shaft 408 changes continuously during the rotation of the first gear 405. This causes the connecting shaft 408 to drive the moving rod 402 to perform a cyclical linear motion along the limiting seat 403. During the reciprocating motion of the moving rod 402, one end of it continuously strikes the vibrating plate 6. The vibration generated by the striking gives energy to the dust particles on the side wall surface of the dust hopper 2, thus reducing their density. The adhesion between the material and the side wall makes it easier for dust to fall off the side wall. When the dust falls into the discharge hopper 3, the second motor 506 is started. At this time, the output end of the second motor 506 drives the second transmission wheel 505 to rotate. The rotation of the second transmission wheel 505 drives the rotating shaft 507 to rotate. The rotation of the rotating shaft 507 realizes the rotation of the distribution plate 502. The rotation of the distribution plate 502 can also play a certain role in clearing the ash discharge port, so that the dust can be discharged more smoothly. While the second transmission wheel 505 is rotating, it drives the first transmission wheel 503 to rotate through the transmission belt 504. The rotation of the first transmission wheel 503 drives the stirring shaft 501 to rotate. When the stirring shaft 501 rotates, the several rake teeth distributed on its outer wall can repeatedly stir the dust accumulated around it, thereby destroying the mutual support force between the dust particles in the arched structure at the ash discharge port, so that the dust above can continue to fall.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
