Dust removal equipment for intermediate frequency furnace

Abstract

The invention discloses a dust removal device for an intermediate frequency furnace. The dust removal device includes a fan, a motor, a dust collector body, a smoke collection hood and a pipe; the smoke collection hood is provided with a smoke collection port and a discharge port, and the smoke collection port covers The area of ​​the intermediate frequency furnace in the vertical state and the overturned state is used to capture the dust-containing flue gas generated at the intermediate frequency furnace; one end of the pipe is connected to the exhaust port of the smoke collection hood, and the other end of the pipe is connected to the fan. It communicates with the air inlet and discharges to the dust collector body; the dust collector body includes a filter bag and a flower plate, the filter bag is used to filter the dust in the flue gas, and the flower plate is used to discharge the filtered flue gas. The dust removal equipment has the advantages of high efficiency, energy saving and small footprint.

Description

technical field [0001] The invention relates to a dust removal device for an intermediate frequency furnace, which is mainly used for flue gas treatment in the metallurgical field. Background technique [0002] The medium frequency induction furnace is a power supply device that converts the AC power with a power frequency of 50 Hz into an intermediate frequency of 300 Hz to 20K Hz. It converts the three-phase power frequency AC power into DC power after rectification, and then converts the DC power into an adjustable medium frequency current, which is supplied by a capacitor. And the medium-frequency alternating current flowing in the induction coil generates high-density magnetic force lines in the induction coil, and cuts the metal material contained in the induction coil, generating a large eddy current in the metal material. [0003] This eddy current also has some properties of the intermediate frequency current, that is, the free electrons of the metal itself flow in ...

AI Technical Summary

Problems solved by technology

[0008] At present, the dust-containing flue gas of the intermediate frequency furnace is mainly collected by the umbrella-shaped rotating hood. The umbrella-shaped rotating hood is erected above the furnace mouth of the intermediate frequency furnace, and the outdoor dust removal of the intermediate frequency furnace is carried out through the dust removal equipment installed outside the factory building. On the one hand, when the material is fed and tapped, the furnace mouth is outside the mouth of the rotating hood, and the flue gas cannot be effectively sucked away, causing the dust-containing flue gas to directly diffuse into the workshop, causing environmental pollution; on the other hand On the one hand, it takes about 60 to 130 meters long to discharge the dust-containing flue gas from the factory building to the outside of the factory building, and the dust removal equipment outside the factory building occupies a large area of ​​land outside the factory building, resulting in large investment in equipment construction and high use costs
