[0002] In the power generation process of thermal power plants, coal is needed to provide heat for power generation. During the transportation of coal, suspended coal powder is easily generated, which not only pollutes the environment, but also easily causes safety accidents such as dust explosions. In actual production, spray dust suppression devices are generally required to prevent coal powder from floating and reduce dust.

[0003] For example, the Chinese patent publication No. CN218707477U discloses a coal conveyor belt spray dust removal device for a thermal power plant; the Chinese patent publication No. CN217961831U discloses a coal conveyor belt spray dust removal device for a thermal power plant;

First, the dust reduction space can only radiate to the range of the spray, and the dust reduction space range is relatively small. Secondly, the clean water sprayed for dust reduction will be directly consumed and fall on the transported coal, resulting in the need to consume a large amount of water resources for dust reduction, and the coal will also be wetted, resulting in the problem of increased water content in the coal.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1-6 shown, the present invention has the following specific embodiments.

[0029] Embodiment 1

[0030] A coal conveying spray dust removal device for a thermal power plant, including a dust removal cylinder 1, a power motor 2 fixedly connected by a bracket at a position near the rear edge inside the dust removal cylinder 1, an exhaust fan blade 201 fixedly connected to the output end of the power motor 2, a plurality of air inlets 101 opened on both sides of the dust removal cylinder 1, an arc-shaped collection box 3 placed inside the dust removal cylinder 1, an infusion tube 5 fixedly connected above the dust removal cylinder 1, a plurality of atomizing nozzles 501 fixedly connected below the infusion tube 5, the atomizing nozzles 501 passing through the dust removal cylinder 1 and located at the top of the dust removal cylinder 1, and support slide rails 6 fixedly connected symmetrically before and after on both sides of the dust removal cylinder 1, a limit slide groove 601 opened inside the support slide rails 6, a limit slider 701 slidably installed inside the limit slide groove 601, and a support leg 7 fixedly connected below the limit slider 701.

[0031] In this implementation, starting the power motor 2 can drive the rotation of the air extraction blade 201. The rotation of the air extraction blade 201 can extract the air inside the dust removal cylinder 1. The air around the dust removal cylinder 1 will be sucked into the inside of the dust removal cylinder 1 from the air inlet 101 and the rear opening, and the coal ash mixed in the air will be carried and sucked into the inside of the dust removal cylinder 1. The clear water is transported to the atomizing nozzle 501 by the infusion pipe 5. The atomizing nozzle 501 can atomize and spray the clear water into the inside of the dust removal cylinder 1 to perform a dust reduction operation on the sucked coal ash. Using a fan to suck the nearby coal ash, compared with the existing direct spraying, the suction radiation range is larger, and it is more suitable for the dust removal scenario of coal transportation. Part of the sprayed water mist will be sucked and blown away, and the other part will carry the settled coal ash and fall into the arc-shaped collection box 3, which can recover a part of the dust reduction water as much as possible.

[0032] Example 2

[0033] A baffle 102 is fixedly connected to the front of the dust removal cylinder 1. An installation control hole 103 is opened on the front of the baffle 102. The installation control hole 103 cooperates with the arc-shaped collection box 3. A plurality of partition plates 301 are fixedly connected inside the arc-shaped collection box 3. A liquid discharge connection head 304 is fixedly connected to the front of the arc-shaped collection box 3. A limit groove 4 is opened on the front of the baffle 102. A return spring 401 is fixedly connected inside the limit groove 4. The other end of the return spring 401 is fixedly connected to a limit pin 402. A displacement handle 403 is fixedly connected to the limit pin 402. A limit hole 302 is opened on the upper surface of the arc-shaped collection box 3. The limit hole 302 cooperates with the limit pin 402. A handle 303 is fixedly connected to the front of the arc-shaped collection box 3.

[0034] In this implementation, by inserting the arc-shaped collection box 3 into the installation control hole 103, the arc-shaped collection box 3 is slidably installed inside the dust removal cylinder 1. The partition plates 301 can divide the inside of the arc-shaped collection box 3 into multiple areas, and then store the settled sewage inside the arc-shaped collection box 3 to preliminarily precipitate the dust reduction sewage, so that the impurities are retained inside the arc-shaped collection box 3 as much as possible. The liquid discharge connection head 304 can be used for the recovery pipeline to recover the recovered clear water. The handle 303 can facilitate the user to pull. The return spring 401 can provide a certain thrust for the limit pin 402. The limit pin 402 will be inserted into the limit hole 302 under the thrust, and then the arc-shaped collection box 3 is fixed inside the dust removal cylinder 1. The displacement handle 403 can be used to drive the movement of the limit pin 402.

[0035] Example 3

[0036] A threaded adjustment rod 602 is rotatably installed in the limit sliding groove 601. One end of the threaded adjustment rod 602 is fixedly connected with a knob. A threaded through hole 702 is formed in the limit sliding block 701. The threaded through hole 702 is in threaded cooperation with the threaded adjustment rod 602. A threaded sleeve block 703 is embedded and installed at the lower end of the support leg 7. A threaded support column 704 is installed in the threaded sleeve block 703 by threads.

A fixed foot 707 is fixedly connected below the ball cage 706.

[0037] In this implementation scheme, through the threaded cooperation between the limit sliding groove 601 and the threaded through hole 702, the threaded adjustment rod 602 is driven to rotate by using the knob. The rotation of the threaded adjustment rod 602 can drive the limit sliding block 701 to move. The movement of the limit sliding block 701 can drive the fixed foot 707 to move, enabling it to adapt to coal conveying devices of different sizes. The threaded support column 704 is installed in the threaded sleeve block 703 by threads. Rotating the threaded support column 704 can drive the fixed foot 707 to move up and down to adjust the height of the fixed foot 707. The ball head 705 is in rotational cooperation with the ball cage 706, enabling the fixed foot 707 to be rotated and adjusted, and then the fixed foot 707 is fixed on the coal conveying equipment.

[0038] The working principle and usage process of the present invention: By connecting the infusion tube 5 to the water delivery pipeline, clear water is conveyed to the atomizing nozzle 501. The atomizing nozzle 501 can atomize and spray the clear water into the dust removal cylinder 1. The power motor 2 is started to drive the air extraction blade 201 to rotate. The rotation of the air extraction blade 201 extracts the air inside the dust removal cylinder 1. The air around the dust removal cylinder 1 will be inhaled into the dust removal cylinder 1 from the air inlet 101 and the rear opening. The coal ash mixed in the air will be carried and inhaled into the dust removal cylinder 1. The dust in the air around the coal conveying equipment will also be inhaled into the dust removal cylinder 1. The sprayed clear water is used to reduce the dust of the inhaled coal ash in the air. A part of the clear water will directly fall into the arc-shaped collection box 3. The purification equipment is connected through the liquid discharge connection head 304 to recycle and treat a certain amount of dust-removing water.
