The water tank 12 is connected with the dust collecting cylinder 2. The connection between the water tank 12 and the dust collecting cylinder 2 is fixedly connected with a filter screen 13. The water tank 12 has a submersible pump 14 inside. The output end of the submersible pump 14 is fixedly connected with a water pipe 15. The water pipe 15 passes through the top of the water tank 12 and extends upward. The inner wall of the upper half of the dust collecting cylinder 2 is fixedly connected with two coils 16 distributed up and down. The coils 16 are spiral-shaped. The outer ends of the coils 16 pass through the dust collecting cylinder 2 and are fixedly connected with the water pipe 15. The bottom of the coils 16 is fixedly connected with a number of uniformly distributed nozzles 17. The top of the dust collecting cylinder 2 is fixedly connected with an air outlet pipe 20 and a water inlet pipe 22. A fan 21 is installed in the air outlet pipe 20. The bottom of the dust collecting cylinder 2 is fixedly connected with a sewage pipe 23, and a valve is installed at the bottom of the sewage pipe 23.

[0016] Two cleaning ports 7 are provided on the left and right walls of the dust removal box 1. The left cleaning port 7 is respectively located at the left end top of the filter plate 1 5 and the bottom of the left wall of the dust removal box 1, and the right cleaning port 7 is located at the right end top of the filter plate 2 6. The inner wall of the cleaning port 7 is rotatably connected to a sealing door 8, and a lock buckle 9 is fixedly connected between the outer wall of the sealing door 8 and the outer wall of the dust removal box 1.

[0017] A partition 18 is provided below the coil 16 , and the partition 18 is fixedly connected to the inner wall of the dust removal cylinder 2 . Evenly distributed leakage holes 19 are provided on the top of the partition 18 . The partition 18 is above the coil 16 at the bottom.

[0018] The dust collecting cylinder 2 is layered by using a partition plate 18, so that the smoke from the leakage hole 19 can be more fully contacted with the water mist. The fan 1 4, the fan 2 11 and the fan 3 21 are all suction fans.

[0019] When low-carbon ferrochrome is produced and processed, the fan 4 is a suction fan, and the fan 4 starts to work to suck the flue gas into the dust removal box 1 through the air inlet pipe 3.

[0020] Initial filtration stage: The flue gas first passes through the filter plate 15 located at the top. Since the filter plate 15 is tilted to the lower left, the large particles of dust and impurities in the flue gas will slide along the filter plate 15 to the left end of the filter plate 15 under the action of gravity and inertia. Then, the flue gas passes through the filter plate 26 located at the bottom. The filter plate 26 is tilted to the lower right, which can capture more fine dust particles and further purify the flue gas.

[0021] Secondary filtration stage: After the flue gas is filtered by the filter plate 1 5 and the filter plate 2 6, the fan 2 11 is a suction fan. Under the action of the fan 2 11, the flue gas enters the dust removal cylinder 2 through the connecting pipe 10. The dust removal liquid 24 is inside the dust removal cylinder 2. At this time, the submersible pump 14 extracts the dust removal liquid 24 from the water tank 12 and transports it to the two coils 16 through the water pipe 15. The water flows in the coil 16 and is sprayed out through the nozzle 17 to form fine water mist. The water mist is fully in contact with the flue gas, and the residual dust and harmful substances in the flue gas are adsorbed and settled to the bottom of the dust removal cylinder 2;

[0022] The dust removal water settled to the bottom of the dust removal cylinder 2 is filtered by the filter screen 13 and enters the water tank 12 again, thus realizing the recycling of the dust removal solution 24;

[0023] Exhaust stage: After multiple filtrations and water mist purification, the smoke is finally discharged through the exhaust pipe 20 by the fan 3 21. The fan 3 21 ensures the smooth exhaust of the smoke. This utility model only protects the mechanical part, and the functions realized by the software control part are not within the protection scope of this utility model.
