A steel plant dust collector is a device specifically designed to collect and filter dust, particulate matter, and pollutants generated during the production process of the steel industry. Metal dust collector system. Its main working principle is to separate particles and pollutants from the air through physical, chemical, or electrical principles, in order to achieve the goal of purifying the air. The working principle can be divided into the following steps: air entering the dust collector, pre-treatment, airflow dispersion, filtration, particle aggregation, condensate collection, and clean air discharge.
