The dust removing system is mainly a centralized dust removing system in the industry at present, for example, a feed bin feeding process of steelmaking and ironmaking of steel enterprises adopts scattered storage, scattered screening, scattered weighing and intermittent feeding, but the dust removing system adopts a centralized large-scale dust removing system for unified treatment and dust fall emission, and for example, the smelting process of steelmaking and smelting basically adopts intermittent and time-division smelting operation from feeding to smelting, but the dust removing system also lays a smoke dust pipeline outside a factory building, and adopts centralized large-scale dust removal centralized unified treatment and dust fall emission. The centralized dust removal system has the advantages of large investment, long pipelines, high energy consumption, large occupied area, large noise and high operation and maintenance cost, the dust removal operation process is not matched with the production process, the design air quantity of the fan is too large, the energy waste is serious, the total dust emission amount is obviously increased, and the system must be operated throughout the year, so that huge energy consumption burden is definitely brought to enterprises. Although some systems are provided with frequency converters to try to reduce energy consumption, due to the huge and complex of the systems, the balance between low-frequency operation and pipeline air quantity is difficult to realize, and in actual production, the system is always in a high-speed full-load operation state, and in order to ensure the dust removal effect, only high energy consumption can be used as a cost, and the dust removal system which is not matched with the production process is extremely not suitable for the national 'new productivity', 'energy conservation, emission reduction and carbon reduction' policies, and needs to be improved.
