Description

Technical Field

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

[0002] Steelmaking converters produce a large amount of flue gas during the steelmaking process. The flue gas contains a large amount of dust, and the dust concentration can reach 150-200 mg / Nm3. At the same time, the flue gas has the characteristics of high temperature, toxicity, flammability and explosiveness. Therefore, the flue dust must be removed before it can be discharged into the air, otherwise it will cause considerable damage to the ecological environment.

[0003] At present, the common equipment used for dust removal in steel mills is the fog cannon. When in use, although the vertical and horizontal directions of the fog cannon barrel can be adjusted, after the direction is adjusted, the fog cannon barrel still sprays dust in a fixed posture. This results in the dust removal range of the existing fog cannon being still relatively narrow, resulting in insufficient dust removal effect. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a dust removal device for steelmaking, which, when in use, can implement spray dust reduction in a wider range and has a better dust removal effect.

[0006] A dust removal device for steelmaking, comprising a water tank, and further comprising:

[0007] The fog cannon barrel is mounted and fixed on the top of the water tank;

[0008] The high-pressure fan is installed and fixed at the tail of the fog cannon barrel;

[0009] A high-pressure water pump, a water distribution pipe and an atomizing nozzle; the water distribution pipe is a closed-loop tube body and is fixed on the inner wall of the middle part of the fog cannon barrel. A plurality of atomizing nozzles are evenly arranged on the inner side of the water distribution pipe along the circumferential direction. The high-pressure water pump is installed and fixed on the top of the water tank, and the water inlet is connected to the inside of the water tank, and the water outlet passes through the bottom wall of the fog cannon barrel and is connected to the water distribution pipe;

[0010] Swing blade and reciprocating swing driving mechanism; the swing blade is rotatably arranged on the inner wall of the spray port of the fog cannon barrel, and multiple swing blades are evenly arranged along the left and right directions, and each swing blade is driven by the reciprocating swing driving mechanism to synchronously swing back and forth to the left and right.

[0011] As an improvement, the two ends of the swing blade are respectively fixed with rotating shafts rotatably connected to the top wall and bottom wall of the fog cannon barrel.

[0012] As an improvement, the reciprocating swing drive mechanism includes an electric telescopic rod and a connecting rod; the rear side of each of the swing blades is hinged with the same connecting rod, and a connecting rod through-hole is reserved on the right side wall of the fog cannon barrel for the connecting rod to pass through. The outer shell of the electric telescopic rod is fixed to the outer wall of the fog cannon barrel by a mounting bracket, and the telescopic shaft end is fixedly connected to the right end of the connecting rod.

[0013] It is worth mentioning that the high-pressure fan, high-pressure water pump and electric telescopic rod used in this technical solution are all existing equipment well known to those skilled in the art, and their use and control methods are all existing technologies.

[0014] The advantages of the utility model compared with the prior art are:
