Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1 - Figure 4 , a defluorination device for activated carbon production, comprising a defluorination box 1, an air inlet pipe 2 fixedly mounted on one side of the defluorination box 1, a sponge plate 3 for preliminary cleaning and filtration fixedly mounted in the inner cavity of the defluorination box 1, and one side of the sponge plate 3 is communicated with one end of the air inlet pipe 2, a filter plate 4 for thorough cleaning and filtration is mounted above the sponge plate 3, and the filter plate 4 is fixedly mounted in the inner cavity of the defluorination box 1, an air outlet pipe 6 is fixedly mounted on the top of the defluorination box 1, a cleaning structure for avoiding blockage inside the air inlet pipe 2 is fixedly mounted in the inner cavity of the air outlet pipe 6, and a control structure for monitoring the cleaning and filtration effect is rotatably mounted in the inner cavity of the air outlet pipe 6;

[0024] The cleaning structure includes a rotating rod 501, which is located at the axis of the inner cavity of the air intake pipe 2. A support frame 508 for supporting the rotating rod 501 is rotatably installed on the outer wall of the rotating rod 501, and the support frame 508 is fixedly connected to the inner wall of the air intake pipe 2. A rotating ring 509 is installed on one side of the support frame 508, and the rotating ring 509 is fixedly sleeved on the outer wall of the rotating rod 501. A plurality of propeller blades 510 for driving the rotating rod 501 to rotate are fixedly installed on the outer wall of the rotating ring 509. Scraping structures for cleaning the inner wall of the pipe are fixedly installed at both ends of the rotating rod 501. The rotating rod 501 is driven by the propeller blades 510 to connect the rotating ring 509 to control the rotation of the scraping structure to clean the inner wall of the air intake pipe 2.

[0025] Specifically, the end of the air intake pipe 2 away from the sponge plate 3 is fixedly connected to the external air supply pipe through a flange, and one end of the rotating rod 501 passes through the air intake pipe 2 and extends to be plugged into the inside of the external air supply pipe, so that the two sets of scraping structures are respectively located inside the air intake pipe 2 and the external air supply pipe, so as to facilitate scraping and cleaning of the soot that may accumulate on the inner wall of the pipe;

[0026] The scraping structure includes a rotating disk 502, which is fixedly mounted on one end of the rotating rod 501. The outer wall of the rotating disk 502 is fixedly connected to a support tube 503. A connecting frame 504 is provided on the outer sliding sleeve of the support tube 503. A scraper 505 for scraping and cleaning is fixedly mounted on the end of the connecting frame 504 away from the support tube 503. The scraper 505 is in contact with the inner wall of the intake pipe 2.

[0027] In order to ensure that the scraping structure inserted into the external gas pipe can adapt to different pipe sizes, the inner cavity of the support tube 503 is fixedly installed with a spring 506 for changing the position of the scraper 505.

The arrangement of multiple groups of scrapers 505 expands the cleaning range of the device, works alternately with each other, improves the working efficiency of the device, and shortens the working time of the device.

[0030] Example 2: Please refer to Figure 1 、 Figure 2 、 Figure 5The control structure includes a driving motor 601, which is fixedly mounted on the top surface of the air outlet pipe 6. The output shaft of the driving motor 601 is fixedly mounted with a curved rotating rod 602, and the curved rotating rod 602 is rotatably mounted in the inner cavity of the air outlet pipe 6.

[0031] Both ends of the outlet pipe 6 are provided with an outlet, and the throttle plug 606 and the throttle plate 607 are respectively located in the outlets at both ends of the outlet pipe 6. The outlet at the end corresponding to the throttle plug 606 is fixedly installed with a reflux pipe 611 for re-transporting the gas to the inside of the defluorination box 1 through a flange. The outlet at the end corresponding to the throttle plate 607 is fixedly connected to the external output pipe through a flange.

[0032] Specifically, a fixing frame 609 for supporting the bent rotating rod 602 is rotatably mounted on the bottom end of the bent rotating rod 602 via a bearing, and the fixing frame 609 is fixedly connected to the inner wall of the outlet pipe 6. A sealing silicone ring 610 is fixedly connected to the outer wall of the throttle plug 606, effectively enhancing the airtightness of the device. The throttle plate 607 is set to a silicone material, effectively enhancing the cut-off sealing effect of the device and strengthening the sealing of the device.

At the same time, the rotating block 603 drives the pushing rod 604 to push the throttle plug 606 into the gas outlet at the end corresponding to the throttle plug 606, thereby closing the reflux pipe 611 and allowing the gas to be discharged from the external output pipe. When the monitor 608 detects that the fluorine content of the filtered gas does not reach If the standard is excluded, the driving motor 601 is connected to the bent rotating rod 602 to drive the rotating block 603 to rotate in the opposite direction, so that the rotating block 603 drives the moving rod 605 to push the throttle plate 607 to insert into the air outlet at the end corresponding to the throttle plate 607. At the same time, the rotating block 603 drives the pushing rod 604 to pull the throttle plug 606 away from the air outlet at the end corresponding to the throttle plug 606, and then closes the external output pipe, allowing the gas to be re-delivered from the reflux pipe 611 to the inside of the defluorination box 1 for another defluorination filtration.

A water storage tank 10 is fixedly installed at the bottom of the inner cavity of the defluorination box 1;

The water supply pipe 11 is fixedly connected to the spray pipe 7, and a water pump for boosting is fixedly installed on the outer wall of the water supply pipe 11.

[0037] The working principle of this utility model is:

[0038] First, the gas is transported to the sponge board 3 through the air intake pipe 2, and at the same time, the propeller blade 510 is driven by the gas flow to connect the rotating ring 509 to drive the rotating rod 501 to rotate, so that the rotating rod 501 drives the support tube 503 to control the scraper 505 to rotate accordingly, so as to clean the inner wall of the air intake pipe 2, and the scraper 505 is squeezed by the inner wall of the pipe, and the movable rod 507 is connected to compress the spring 506 to shorten the distance between the scraper 505 and the support tube 503, so that the cleaning structure can automatically adjust the distance between the scraper 505 and the support tube 503 according to the diameter of the pipe wall, so as to ensure that the scraper 505 is always in close contact with the inner wall of the pipe; after the gas enters the sponge board 3, water is sprayed by the spray pipe 7 to keep the sponge board 3 in a wet state at all times, and the gas flows upward through the sponge board 3, and the water is used to absorb the fluorine-containing flue gas in the flue gas, completing the preliminary defluorination treatment of the flue gas. The filtered wastewater drips onto the guide plate 8, and the water and ash are separated by the filter tube 9. The water flow continues to drip into the water storage tank 10, and the water supply pipe 11 is used to transport it to the spray pipe 7 for reuse; the gas continues to flow upward, passes through the filter plate 4 for double filtration and cleaning, and is discharged from the outlet pipe 6. When the monitor 608 detects that the fluorine content of the filtered gas does not meet the exclusion standard, the driving motor 601 is connected to the bent rotating rod 602 to drive the rotating block 603 to rotate in the opposite direction, so that the rotating block 603 drives the moving rod 605 to push the throttle plate 607 to insert into the air outlet at the end corresponding to the throttle plate 607. At the same time, the rotating block 603 drives the push rod 604 to pull the throttle plug 606 away from the air outlet at the end corresponding to the throttle plug 606, and then closes the external output pipe, allowing the gas to be transported from the reflux pipe 611 to the inside of the defluorination box 1 for another defluorination filtration.
