Description

Technical Field

[0001] The utility model relates to a flue gas dust removal washing tower, in particular to a flue gas dust removal washing tower with an internal cleaning function, belonging to the technical field of washing towers. Background Art

[0002] In the prior art, for example, an invention with application number 202110460071.X discloses a washing tower with a dust removal function. In order to solve the problem that the gas generally contains a large amount of impurities and dust, and the presence of dust easily affects the operation of the washing tower, a first filter is installed inside the main body of the washing tower, and through the action of the cleaning motor, the rotating shaft connected to its driving end can be rotated, and then the cleaning rod connected to the outside of the rotating shaft through the connecting sleeve can be rotated, so that the surface of the first filter can be cleaned by using the cleaning brush arranged on the outside of the cleaning rod, which can effectively prevent dust impurities in the gas from falling onto the surface of the first filter, thereby affecting the operation of the washing tower. This arrangement can effectively perform secondary dust removal treatment on the gas, thereby preventing dust from being contained in the gas.

[0003] Similar to the above application, there are still some shortcomings:

[0004] The dust inside the flue gas will not only adhere to the mesh plate, but also to the inner wall of the tower body. The sprayed cleaning liquid falls vertically after passing through the filler, and it is difficult to flow down along the inner wall of the tower body. Therefore, the dust adhering to the inner wall of the tower body is difficult to be cleaned, and long-term accumulation affects the flow effect of the flue gas.

[0005] For this purpose, a flue gas dust removal washing tower with internal cleaning function is designed to optimize the above problems. Utility Model Content

[0006] The main purpose of the utility model is to provide a flue gas dust removal and washing tower with an internal cleaning function. A rotating lifting mechanism composed of a motor, a turntable, a rectangular rod, a rectangular sleeve, a screw and an inner screw tube is arranged at the inner bottom of the tower body, and then used in conjunction with a scraper on a cross bar, so that during use of the device, the scraper can be controlled to rotate and lift in contact with the inner wall of the tower body, so as to clean the dust on the inner wall of the tower body and ensure the cleanliness of the inner wall of the tower body. A truncated cone-shaped guide cover is arranged below the filler, so that when the cleaning liquid falls through the filler, part of the liquid can flow downward along the inner wall of the tower body under the guidance of the guide cover, so as to actively clean the dust on the inner wall of the tower body, thereby improving the practicality of the device. A rubber plate is slidably arranged on one side of the scraper close to the inner wall of the tower body, and used in conjunction with a spring, so that during the cleaning process, it can be ensured to fit the inner wall of the tower body, thereby improving the cleaning effect.

DETAILED DESCRIPTION

[0024] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0025] like Figure 1-Figure 4 As shown, this embodiment provides a flue gas dust removal and washing tower with an internal cleaning function, including a tower body 1, a vortex generator 2 installed at the air inlet at the bottom of the tower body 1, a mesh plate 4 horizontally fixed between the inner walls of the tower body 1, a filler 3 filled on the top of the mesh plate 4, a spray pipe 5 perpendicular to the inner wall of the tower body 1 and located above the filler 3, and a nozzle 6 evenly installed at the bottom of the spray pipe 5, a motor 7 is installed at the middle position of the mesh plate 4 at the bottom of the tower body 1, a turntable 8 is horizontally installed at the output end of the motor 7, rectangular rods 9 are vertically installed on both sides of the bottom of the turntable 8, and rectangular sleeves 10 are vertically slidably installed on the rectangular rods 9, a screw 11 is rotatably installed on the top of the vortex generator 2, an inner spiral tube 12 is threadedly installed on the screw 11, both sides of the inner spiral tube 12 are fixedly connected to the bottom of the rectangular sleeve 10, and a cross bar 13 is symmetrically installed on the outer side of the inner spiral tube 12, and a scraper 14 that fits the inner wall of the tower body 1 is fixed on the end of the cross bar 13 away from the inner spiral tube 12.

[0026] General working principle: When the washing tower is in use, the flue gas passes through the vortex generator 2 and enters the interior of the tower body 1. At the same time, the washing liquid in the spray pipe 5 is sprayed out through the nozzle 6, falls into the interior of the filler 3 and is fully mixed with the flue gas to wash the flue gas. During the flow of the flue gas, the dust inside the flue gas will adhere to the interior of the tower body 1. In order to ensure the cleanliness of the interior of the tower body 1, the motor 7 is started regularly to control the rotation of the turntable 8. The rotation of the turntable 8 cooperates with the rectangular rod 9 and the rectangular sleeve 10 to control the rotation of the inner screw 12. When the inner screw 12 rotates, it drives the scraper 14 to clean the inner wall of the tower body 1. At the same time, the inner screw 12 will also move up and down along the screw 11, so the scraper 14 can thoroughly clean the interior of the tower body 1.

[0027] In this embodiment, the top of the turntable 8 is conical, and an anti-stick coating is provided on the top of the turntable 8 .

[0028] Partial working principle: After the washing liquid drops onto the top of the turntable 8, it will flow downward along the surface of the turntable 8 to avoid the accumulation of the washing liquid.

[0029] In this embodiment, a limiting block is fixed on the top of the screw rod 11, and a rubber buffer pad is disposed on the bottom of the limiting block.

[0030] Partial working principle: During the rising process of the inner spiral tube 12 , the limit block can limit the maximum rising height of the inner spiral tube 12 to prevent the inner spiral tube 12 from being separated from the screw rod 11 .

[0031] In this embodiment, the scraper 14 is arranged perpendicular to the horizontal plane, and a reinforcing rod is provided between the outer side of the scraper 14 and the cross bar 13 .

[0032] Partial working principle: When the scraper 14 rotates circumferentially along the inner wall of the tower body 1 , the reinforcing rod can improve the stability between the scraper 14 and the cross bar 13 .

[0033] In this embodiment, a deflector 15 is fixed below the mesh plate 4 . The bottom of the deflector 15 is open in a trumpet shape, and a gap is left between the outer side of the deflector 15 and the inner wall of the tower body 1 .

[0034] Partial working principle: When the washing liquid drips downward through the filler 3, the washing liquid falling on the outside of the guide cover 15 will spread outward and fall along the inner wall of the tower body 1, and the dust inside the tower body 1 will be self-cleaned.

[0035] In this embodiment, a slot 16 is provided along the length direction on one side of the scraper 14 close to the inner wall of the tower body 1 , a rubber plate 17 is slidably installed inside the slot 16 , and a spring 18 is provided between the rubber plate 17 and the inner bottom of the slot 16 .

[0036] Partial working principle: During the sliding process of the scraper 14, since the spring 18 always provides thrust to the rubber plate 17, it can ensure contact with the inner wall of the tower body 1 to ensure the cleaning effect.

[0037] In this embodiment, the side of the rubber plate 17 that contacts the tower body 1 is arc-shaped.

[0038] Partial working principle: The arc-shaped side of the rubber plate 17 can reduce the resistance of the scraper 14 when it slides.

[0039] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
