Its working principle is that the smoke inlet pipe discharges the poorly generated flue gas in production, and the solid particles contained in the flue gas are preliminarily filtered through the set filter net. The filtered solid particles are stored in the tube collection box 7 under the influence of gravity. The filtered flue gas flows into the second tube body through the VRI reactor 5, and then flows into the adsorbent 3 through the second tube body. Then, the fluoride contained in the flue gas is adsorbed by the adsorbent 3. The flue gas and the adsorbent 3 are fully contacted through the set VRI reactor 5, and then the motor is started by the switch group, and the output shaft of the motor drives the shaft to rotate. The moving shaft drives the fixed block to rotate, and the rotating fixed block drives the fan blades to rotate. The adsorbent 3 is stirred by the rotating fan blades, so that the flue gas and the adsorbent 3 are further fully contacted, thereby reducing the fluoride content in the flue gas, and then the solid particles in the flue gas are intercepted again by the glass fiber filter plate to prevent the solid particles from being discharged to the outside with the flue gas and affecting the ecological environment. Then the pump is started through the switch group, and the water in the water tank is pumped out through the water inlet pipe of the pump, and then the water is transported to the inside of the condenser through the water supply pipe connected to the water outlet of the pump, and then the moisture in the flue gas is condensed through the condenser, and then the used water flows into the inside of the water tank through the drain pipe for recycling, which saves water resources and improves water utilization. Then the moisture in the flue gas is adsorbed by the activated carbon plate, thereby completing the filtration and purification of the flue gas generated in the electrolytic aluminum production process.

[0040] Specifically, when the device provided by the utility model is used for the production of electrolytic aluminum liquid, the generated flue gas is purified. When in use, the flue gas enters, is filtered through the preliminary gas filter component 6, and the filtered solid impurities enter the collection box 7, and then the flue gas enters the adsorbent 3 in the purification device body 1 for adsorption. The VRI reactor 5 is set to make the flue gas and the adsorbent 3 fully contact, and then is processed through the purification device body 1 and finally discharged. After use, the adsorbent 3 can be filtered and recycled through the filter component 2, and the solid impurities in the collection box 7 are easily processed through the cleaning component 8. When the filter component 2 is in use, the infusion pump 26 is started, and the adsorbent 3 enters the filter box 22, is filtered through the water filter 24, and then enters the liquid storage tank 21. When in use, through The submersible pump 27 can transport the adsorbent 3 back to the purification device body 1. When the water filter 24 needs to be cleaned, pull the limit plug 282 to disengage it from the limit plug hole, and then pull the sealing cover 25 to move. The movement of the sealing cover 25 drives the disassembly and assembly seat 23 to move, and the disassembly and assembly seat 23 is moved out of the filter box 22. Then the water filter 24 can be taken out for cleaning, so that when the device is in use, it is convenient to filter and recycle the adsorbent 3, which improves the practicality of use. When the cleaning component 8 is in use, pull the pull rod 82, and the pull rod 82 drives the wedge-shaped blocking block 83 to move down and compress the return spring 84, so that the wedge-shaped blocking block 83 is disengaged from the discharge pipe 86, and then the solid impurities slide out of the discharge pipe 86, so that when the device is in use, it is convenient to clean the fixed impurities collected in the collection box 7.
