AI Technical Summary

Technical Problem

During the steel strip rolling process, the generation of iron oxide powder, water vapor and flue gas leads to equipment corrosion, dust accumulation and health hazards. Existing dust removal devices have poor dust removal effect and consume a lot of water, which affects equipment and health safety.

Method used

The micro-mist dust removal device utilizes the secondary use of wastewater to atomize and spray water, combined with an air acceleration mechanism, to achieve efficient dust removal, reduce water volume and dust accumulation, improve steel plate surface quality and equipment lifespan.

Benefits of technology

It achieves more efficient dust removal, reduces equipment corrosion and dust accumulation, lowers equipment failure rate and health risks, and extends equipment life.

Abstract

The utility model discloses a micro-fog dust removal device for steel belt rolling, which relates to the technical field of hot rolling production and comprises a U-shaped frame, a supporting plate is mounted on the upper end face of a horizontal section of the U-shaped frame, a filtering module is fixed on one side of the upper end of the supporting plate, an air compressor is fixed on the other side of the upper end face of the supporting plate, and a rotating support is mounted on one side of the U-shaped frame. A water spraying pipe is fixed to the rotating support, and atomizing nozzles are fixed to the water spraying pipe at equal intervals. According to the utility model, water is atomized and sprayed out through secondary utilization of waste water to replace original water spraying, so that the dust removal effect is better, the water spraying amount is greatly reduced, the temperature drop on the surface of a steel plate is greatly reduced, the dust accumulation phenomenon of rolling mill equipment can be effectively reduced, and the phenomenon that dust blocks of a rack fall off and are pressed into the steel plate is reduced; the surface quality of a steel plate is improved, abrasion of fine dust to mechanical operation parts such as bearings is relieved, the dust particle concentration is reduced, and the service life of field valve groups and electrical elements can be prolonged.
