The sulfuric acid production process has very high requirements on the cleanliness of the raw material air. The air contains a large amount of dust particles. When these dust particles enter the sulfuric acid system, the quality of the product will be affected.

When the high-speed moving small particle dust scours and strikes the surface of the internal components of the main fan, it will cause wear and deformation of the impeller flow path of the main fan, increase the sealing gap, affect the airflow movement and reduce the operating efficiency of the equipment. Therefore, it is very necessary to install an air filter before the main fan to filter the dust in the atmosphere and ensure that clean air enters the acid system

Self-cleaning air filter is a new type of high-efficiency air filter with automatic dust removal function, widely used in industrial gas turbines, blast furnace blast, air compressors, etc., especially suitable for environments with high dust concentrations and strict air purification indicators Supporting gas equipment.
