Description

Technical Field

[0001] The utility model relates to the technical field of flue gas dust removal, in particular to a flue gas dust removal device. Background Art

[0002] The function of the dust removal device is to separate dust from flue gas. When the flue gas is passed into the dust removal device for treatment, the flue gas usually carries some water vapor. After the water vapor enters the filter bag of the dust removal device with the flue gas, the dust will adhere to the filter bag and be difficult to remove, thus affecting the subsequent dust removal work.

[0003] However, if only water vapor is filtered, some dust will be carried in the water vapor, so the dust filtration efficiency will be low, which needs to be improved. Utility Model Content

[0017] A condensation device is installed on the side wall of the bracket. The condensation device is arranged between the air intake duct 12 and the dust removal box 11. The condensation device includes a thick condensation tube 14 and a thin condensation tube 15. Condensate is injected into the thick condensation tube 14. Four thick condensation tubes 14 are arranged. The four thick condensation tubes 14 are all connected to the side wall of the bracket. The thick condensation tubes 14 are arranged in pairs, and a pair of thick condensation tubes 14 are arranged in a spire shape. The thin condensation tubes 15 are staggered between a pair of thick condensation tubes 14. When condensate is injected into the thick condensation tubes 14, the condensate can flow and distribute to the thin condensation tubes 15, and condense water vapor in the flue gas through the mesh structure formed by the staggered thin condensation tubes 15.

[0018] A recovery box 13 is fixedly connected to the top wall of the base 1 by bolts, an evaporation tank 2 is provided on the top wall of the base 1, an evaporation dish 21 is fixedly provided on the bottom wall of the evaporation tank 2, the evaporation dish 21 is connected to the recovery box 13, and the recovery box 13 is located below the thick condensation tube 14, so after the thick condensation tube 14 and the thin condensation tube 15 condense the water vapor, the condensed water droplets will fall into the recovery box 13, and then fall into the evaporation dish 21 through the recovery box 13. A reflux hole 22 is provided on the inner wall of the evaporation tank 2, and a reflux pipe 23 is fixedly inserted in the reflux hole 22, one end of the reflux pipe 23 is connected to the evaporation dish 21, and the other end is connected to the intake pipe 12, so that the water vapor evaporated from the evaporation dish 21 can be discharged into the intake pipe for dust removal again, thereby improving the efficiency of dust removal.

[0019] An air intake block 24 is provided at one end of the return duct 23 close to the air intake duct 12, and a one-way groove 25 is opened on the side wall of the air intake block 24 along the flow direction of the return duct 23. The one-way groove 25 is a groove body with a triangular cross-section. The opening of the one-way groove 25 close to one end of the return duct 23 is larger than the opening of the one-way groove close to one end of the air intake duct 12.
