What are the treatment methods of steel dust removal?

The treatment methods of steel dust dust mainly include physical treatment, chemical treatment and resource utilization.

The physical treatment method is to treat the steel dust dust by physical means, mainly including screening, classification, filtration and washing processes. Screening is the separation of dust dust particle size for subsequent treatment; Classification is to separate dust ash into different particle size components according to particle size; Filtration is through the filter screen and other devices to stop the solid particles in the dust dust; Washing is the cleaning of dust dust by water or solution to remove impurities from its surface.

The chemical treatment method is to treat the dust dust of steel by chemical reaction, mainly including acid-base treatment, REDOX treatment and complexation treatment. Acid-base treatment is the use of acid-base solution to dust dust treatment, in order to dissolve or precipitate the harmful substances; REDOX treatment is to transform harmful substances in dust dust into harmless substances through REDOX reaction. Complexation treatment is the use of complexing agent to complex metal ions in dust dust to form stable complexes.

The method of resource utilization is to recycle valuable substances in steel dust dust, including metal recovery, mineral resource recovery and energy recovery. Metal recovery is the extraction of metal substances in dust dust for recycling. Mineral resource recovery is the extraction of mineral substances in dust dust to be used in other industrial fields. Energy recovery is the combustion of organic matter in dust dust to obtain energy.

In summary, there are a variety of treatment methods for steel dust removal, and appropriate treatment methods can be selected according to the actual situation to achieve the dual purpose of environmental protection and resource utilization.
