[0025] The use method and advantages of the utility model: The adsorption device for removing fluorine from waste gas during rare earth extraction, when in use, works as follows:

[0026] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the adsorption device for removing fluorine from waste gas during rare earth extraction is first started when working. The exhaust fan provided inside the exhaust fan 15 is used to extract the waste gas generated during the rare earth extraction process to achieve the extraction of the waste gas. The waste gas first passes through the first layer of fixed activated carbon net 11 provided inside the exhaust fan 15 to complete the preliminary filtration of the first part. Then the waste gas passes through the multiple groups of movable activated carbon nets 11 provided inside the movable frame 9 to complete the adsorption of the second part of the waste gas. After the waste gas passes through the multiple groups of activated carbon nets 11 for a long time, the adsorption energy of the activated carbon nets 11 is greatly improved. The force will be reduced to a certain extent. At this time, a group of driving motors set inside the driving block 2 can be started to drive the rotation of the threaded rod 3, which drives the movable plate 6 to move left and right. At this time, the base 7 and the support frame 8 on the top of the movable plate 6 can move left and right, driving the movable frame 9 on the top of the support frame 8 to move. At this time, a sealing rubber ring is set around the movable frame 9 to seal. While sealing, it can also provide buffering. Then, multiple groups of activated carbon nets 11 can be manually pushed to move the protrusions around them inside the chute 10. , complete the disassembly and installation of multiple sets of activated carbon nets 11, realize the replacement of multiple sets of activated carbon nets 11, and then start the drive motor to realize reverse rotation after the replacement is completed, so that the movable frame 9 returns to the sealing position. Secondly, the submersible pump set inside the water storage tank 18 can be used to spray normal temperature water through the spray head 20 to spray the exhaust gas inside the transport pipe 19, realize the cooling and partial adsorption of the exhaust gas, and make part of the exhaust gas blend with water. Secondly, the exhaust gas enters the interior of the storage box 1 through the transport pipe 19. At this time, the exhaust gas can be discharged through the external pipe using the feeding port 22 Water or an aqueous solution containing sodium hydroxide is added to the interior of the storage box 1 as an absorbent to adsorb the fluorine-containing waste gas. At this time, the pipe blocks the feeding port 22 and seals the storage box 1. When the absorption is completed, another set of drive motors arranged inside the drive block 2 is started to drive the rotation of the drive rod 4, which drives the rotation of the transmission belt 5 and the rotation of the driven rod 12. At this time, the movable rack 13 is driven to move back and forth, and the movable door 14 is driven to rotate around its rotation axis, thereby realizing the opening of the storage box 1 and the discharge of the adsorbed wastewater, which is convenient for manual collection.
