Description

Technical Field

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

[0002] The converter is a steelmaking equipment, which is mainly used to smelt and refine pig iron, scrap steel and other alloy materials to produce steel that meets the requirements. A large amount of smoke and harmful gases will be generated during the steelmaking process. If they are not effectively treated and controlled, they will have an impact on the environment. Therefore, dust removal equipment can be used to treat the smoke and reduce the emission of smoke.

[0003] The existing patent announcement number CN210544058U discloses a sludge dust removal device for converter steelmaking. By setting a coil, a sleeve and a funnel, when in use, the flue gas is spirally transported along the coils on both sides to the inside of the main body, and at the same time, the conduit transports water along the annular pipe and sprays it through the nozzle. Under the action of water pressure, the rubber plug is pushed to move downward along the guide column to overcome the pressure of the compression spring, so that the water is sprayed along the outlet in a mist state, and the water mist absorbs the dust in the flue gas and settles it downward to the inside of the funnel. Under the flushing of the falling water, the dust inside the funnel falls down through the opening inside the spherical baffle and flows into the inside of the sleeve. The coil conducts the high-temperature heat of the flue gas to the inside of the aluminum sleeve, and the aluminum sleeve volatilizes the moisture of the sludge inside it. The volatilized water vapor flows upward and is liquefied into water droplets by the metal funnel to continue to absorb the dust in the flue gas and flow downward. The flue gas is purified repeatedly in this way, and finally the sludge inside the sleeve is discharged through the opening for treatment.

[0004] When the above device removes dust from flue gas, the dust is sprayed and falls by the water source. However, it is difficult for the mist water source to wash away all the diffused dust. After the water on the sleeve is evaporated, the dust is directly discharged and easily raised again, which reduces the impact on the environment. The dust removal efficiency still needs to be improved. In view of the above problems, a converter dust removal device is proposed. Utility Model Content
