Description

Technical Field

[0001] The utility model relates to the technical field of waste gas spraying, in particular to an efficient spraying device for waste gas treatment. Background Art

[0002] After retrieval, a patent with the authorization number of CN218188676U in China discloses an efficient spraying device for waste gas treatment, specifically related to the technical field of waste gas spraying. It includes a spraying tower for waste gas treatment. Two groups of spraying components are arranged up and down inside the spraying tower. Each group of spraying components includes a disc. A cavity is formed inside the disc. A plurality of spraying heads penetrate through the bottom end of the disc. The top end of each spraying head is communicated with the inside of the cavity. In the utility model, a suction pump is used to transport the spraying liquid into the cavities of the two discs. The spraying liquid is sprayed out through the spraying heads at the bottom end of the disc and adheres to the impurities in the waste gas, realizing the treatment of the waste gas. A motor is used to drive the rotation of the rotating shaft. When the rotating shaft rotates, it drives the rotation of the two second filter meshes. When the second filter meshes rotate, they contact the first filter mesh, which can change the aperture between the first filter mesh and the second filter mesh, thereby reducing the speed of the waste gas during the upward movement and enabling the waste gas to fully contact the spraying liquid, greatly improving the treatment effect of the waste gas.

[0003] The above-mentioned efficient spraying device for waste gas treatment has the following deficiencies: There is no mechanism for cleaning the second filter mesh and the third filter mesh located at the bottom end. Since the second filter mesh located at the bottom end comes into contact with the most impurities in the waste gas, after a period of use, more impurities will adhere to the surface and filter holes of the second filter mesh located at the bottom end, resulting in a significant reduction in the speed of the waste gas passing through the second filter mesh. And the impurities treated by the spraying liquid will fall on the third filter mesh, and the impurities will accumulate on the surface of the third filter mesh, causing the third filter mesh to be blocked, making it difficult for the spraying liquid to pass through the third filter mesh, and reducing the filtering efficiency of the third filter mesh for the spraying liquid. Therefore, it is necessary to design an efficient spraying device for waste gas treatment to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a kind of efficient spraying device for waste gas treatment is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An efficient spraying device for waste gas treatment, comprising a spraying tower. A motor is fixedly connected to the bottom of the spraying tower. The output shaft of the motor is fixedly connected to a rotating shaft, and the rotating shaft passes through the bottom of the spraying tower. Two second filter plates are arranged inside the spraying tower. The second filter plate at the top is fixedly connected to the inner wall of the spraying tower. First filter plates are arranged at the bottoms of both second filter plates. The first filter plate at the bottom is fixedly connected to the inner wall of the spraying tower. The rotating shaft is fixedly connected to the second filter plate at the bottom and the first filter plate at the top. The rotating shaft passes through the first filter plate and the second filter plate at the bottom. A third filter plate is fixedly connected to the inner wall at the bottom end of the spraying tower, and the rotating shaft passes through the third filter plate. The rotating shaft is rotatably connected to the third filter plate. A first sleeve plate is fixedly connected to the outer wall at the top end of the rotating shaft. Triangular plates are fixedly connected to both sides of the first sleeve plate. A first cleaning brush is fixedly connected to the top of the triangular plate, and the bristles of the first cleaning brush contact the first filter plate. A second sleeve plate is fixedly connected to the outer wall at the bottom end of the rotating shaft.

A striking plate is slidably connected to the inner wall of the mounting box. A spring is arranged on the side of the striking plate away from the first filter plate. Since the technical means of adjusting the aperture between the first filter plate and the second filter plate while cleaning the first filter plate at the bottom and the third filter plate are adopted, when adjusting the aperture between the first filter plate and the second filter plate, the rotating shaft will also drive the first sleeve plate and the second sleeve plate to rotate, so that the first cleaning brush can move to clean the first filter plate, and the second cleaning brush can clean the third filter plate, ensuring that the spraying liquid can smoothly pass through the third filter plate. At the same time, the striking plate can move to impact the first filter plate and the second filter plate to generate vibrations, causing the impurities in their filter holes to fall off, ensuring that the waste gas can smoothly pass through the first filter plate and the second filter plate. It effectively solves the problem in the background technology that there is no mechanism for cleaning the second filter net and the third filter net at the bottom. A large amount of impurities will adhere to the surface and filter holes of the second filter net at the bottom, resulting in a significant reduction in the speed of the waste gas passing through the second filter net. And the impurities treated by the spraying liquid will fall on the third filter net, and the impurities will accumulate on the surface of the third filter net, causing the third filter net to be blocked, and the spraying liquid is difficult to pass through the third filter net, reducing the filtering efficiency of the third filter net for the spraying liquid. Furthermore, it realizes the technical effect of ensuring the smoothness of the first filter plate, the second filter plate and the third filter plate, ensuring the normal progress of the waste gas treatment work, and improving the efficiency of the waste gas treatment work.

[0010] As a further solution of the present utility model, two observation windows are arranged at the top end of the spray tower.

[0011] As a further solution of the present utility model, a suction pump is installed on the outer wall of the bottom end of the spray tower.

One of the first liquid inlet pipes passes through the outer wall of the spray tower and is placed at the bottom of the third filter plate. A storage tank is fixedly connected to the outer wall of the bottom end of the spray tower. The storage tank is connected to the suction pump through the second liquid inlet pipe. The second liquid inlet pipe is fixedly connected to the liquid outlet of the storage tank. A tee pipe is fixedly connected to the liquid outlet of the suction pump. The two ends of the tee pipe away from the suction pump are respectively fixedly connected to two discs. The two ends of the tee pipe away from the suction pump are respectively arranged in two cavities. An air inlet pipe is installed on the spray tower.

[0012] As a further solution of the present utility model, a base is fixedly connected to the bottom of the spray tower.

[0013] The beneficial effects of the present utility model are as follows:

[0014] The present utility model: By adopting the technical means of adjusting the aperture between the first filter plate and the second filter plate and being able to clean the first filter plate and the third filter plate at the bottom end, when adjusting the aperture between the first filter plate and the second filter plate, the rotating shaft will also drive the first sleeve plate and the second sleeve plate to rotate, so that the first cleaning brush can move to clean the first filter plate, and the second cleaning brush can clean the third filter plate, ensuring that the spray liquid can smoothly pass through the third filter plate. At the same time, the knocking plate can move to impact the first filter plate and the second filter plate to generate vibrations, causing the impurities in their filter holes to fall off, ensuring that the waste gas can smoothly pass through the first filter plate and the second filter plate. It effectively solves the problem in the background technology that there is a lack of a mechanism for cleaning the second filter screen and the third filter screen at the bottom end. A large amount of impurities will adhere to the surface and in the filter holes of the second filter screen at the bottom end, resulting in a significant reduction in the speed of the waste gas passing through the second filter screen. And the impurities treated by the spray liquid will fall on the third filter screen, and the impurities will accumulate on the surface of the third filter screen, causing the third filter screen to be blocked, making it difficult for the spray liquid to pass through the third filter screen, and reducing the filtering efficiency of the third filter screen for the spray liquid. Furthermore, it realizes the technical effects of ensuring the smoothness of the first filter plate, the second filter plate, and the third filter plate, ensuring the normal progress of the waste gas treatment work, and improving the efficiency of the waste gas treatment work.

This achieves the technical effect of ensuring the smooth flow of the first filter plate, the second filter plate and the third filter plate, ensuring the normal progress of the exhaust gas treatment work, and improving the efficiency of the exhaust gas treatment work.

[0024] In this embodiment, four fixing plates 16 are fixedly connected to the top end of the spray tower 1. On one side of two fixing plates 16 on the same horizontal plane that are close to each other, discs 17 are fixedly connected. A cavity 18 is formed in the disc 17. A plurality of atomizing nozzles 19 are fixedly connected to the bottom of the disc 17. The atomizing nozzles 19 communicate with the cavity 18. The disc 17 at the bottom end is sleeved on the rotating shaft 3, and the rotating shaft 3 is rotatably connected to the disc 17.

[0025] In this embodiment, an exhaust pipe 20 is provided at the top of the spray tower 1, and an activated carbon plate is provided in the exhaust pipe 20.

[0026] In this embodiment, an opening is formed at the bottom end of the spray tower 1, and a sealing door 21 is installed at the opening of the spray tower 1.

[0027] In this embodiment, two observation windows 22 are provided at the top end of the spray tower 1.

[0028] In this embodiment, a suction pump 23 is installed on the outer wall of the bottom end of the spray tower 1. The two liquid inlet ports on both sides of the suction pump 23 are respectively fixedly connected to a first liquid inlet pipe 24 and a second liquid inlet pipe 29. One of the first liquid inlet pipes 24 passes through the outer wall of the spray tower 1 and is placed at the bottom of the third filter plate 6. A storage tank 26 is fixedly connected to the outer wall of the bottom end of the spray tower 1. The storage tank 26 is connected to the suction pump 23 through the second liquid inlet pipe 29. The second liquid inlet pipe 29 is fixedly connected to the liquid outlet of the storage tank 26. A three-way pipe 25 is fixedly connected to the liquid outlet of the suction pump 23. The two ends of the three-way pipe 25 away from the suction pump 23 are respectively fixedly connected to two discs 17. The two ends of the three-way pipe 25 away from the suction pump 23 are respectively arranged in two cavities 18. An air inlet pipe 27 is installed on the spray tower 1.

[0029] In this embodiment, a base 28 is fixedly connected to the bottom of the spray tower 1.

[0030] Working principle: When using this device, the spraying liquid is injected into the storage tank 26, and the waste gas is injected into the spraying tower 1 through the intake pipe 27. The waste gas is filtered through the first filter plate 4 and the second filter plate 5. At the same time, the suction pump 23 is started to extract the spraying liquid in the storage tank 26. The spraying liquid is injected into the cavity 18 through the three-way pipe 25, and then into the atomizing nozzle 19, and is sprayed out through the atomizing nozzle 19. The spraying liquid will adhere to the impurities in the waste gas, causing the impurities to fall off. The waste gas that has been filtered and sprayed continues to rise and finally is discharged through the exhaust pipe 20. The waste gas is further filtered through the activated carbon plate in the exhaust pipe 20 to achieve the treatment of the waste gas. When treating the waste gas, the motor 2 can also be started. The output shaft of the motor 2 will drive the rotating shaft 3 to rotate, and the rotating shaft 3 will drive the second filter plate 5 at the bottom and the first filter plate 4 at the top to rotate, changing the aperture of the filter holes between the first filter plate 4 and the second filter plate 5, so as to reduce the rising speed of the waste gas, enabling the waste gas to fully contact with the spraying liquid, thereby improving the effect of treating the waste gas. Since the first filter plate 4 at the bottom contacts the most impurities in the waste gas, and the waste gas filtered by the first filter plate 4 at the bottom contains fewer impurities, after a period of use, more impurities will adhere to the surface and in the filter holes of the first filter plate 4 at the bottom, resulting in a significant reduction in the speed of the waste gas passing through the first filter plate 4 at the bottom, and the rising speed of the waste gas cannot be accurately controlled. While the rotating shaft 3 rotates, it will also drive the first set plate 7 to rotate, and the first set plate 7 will drive the triangular plate 8 to do a circular motion. The triangular plate 8 will drive the first cleaning brush 9 to do a circular motion to clean the surface of the first filter plate 4 at the bottom, removing the impurities on the surface of the first filter plate 4 at the bottom. When the triangular plate 8 moves, its hypotenuse will contact the knocking plate 15. The top of the knocking plate 15 is arc-shaped. If the triangular plate 8 continues to move after contacting the knocking plate 15, the triangular plate 8 will squeeze the knocking plate 15, causing the knocking plate 15 to further retract into the installation box 13. The knocking plate 15 will move along the inner wall of the installation box 13. While the knocking plate 15 moves, it will also squeeze the spring 14 to make the spring 14 contract. When the triangular plate 8 moves past the knocking plate 15, the spring 14 will quickly expand, enabling the knocking plate 15 to quickly rise, and it can also impact the first filter plate 4 and the second filter plate 5 at the bottom, causing them to vibrate, so that the impurities in the filter holes of the first filter plate 4 and the second filter plate 5 fall off, ensuring the smoothness of the first filter plate 4 and the second filter plate 5, thereby ensuring the normal progress of the waste gas treatment work and improving the efficiency of the waste gas treatment work. By setting the atomizing nozzle 19, the spraying liquid can be atomized and sprayed out, increasing the spraying range of the spraying liquid, further enabling the waste gas to fully contact with the spraying liquid, and improving the efficiency and effect of spraying. While the rotating shaft 3 rotates, it will also drive the second set plate 10 to rotate, and the second set plate 10 will drive the second cleaning brush 11 to do a circular motion to clean the top surface of the third filter plate 6.Avoid the accumulation of impurities on the surface of the third filter plate 6, which may cause the spraying liquid to be unable to pass through the third filter plate 6. The spraying liquid filtered by the third filter plate 6 will be pumped out again, and then be pumped out by the suction pump 23 through the first liquid inlet pipe 24 and participate in the spraying work again, effectively saving resources. After completing the spraying work for waste gas treatment, just open the sealing door 21 to maintain the internal parts.
