Scope: This standard specifies the service preparation, on-site inspection and preparation, service, service file management, and requirements for professional cleaning service agencies for the cleaning of industrial dust removal systems. This standard applies to the cleaning of dust removal systems in industrial enterprises. This standard does not apply to dust removal systems used in chemical, mining, tunnel, fireworks, and civilian explosive materials production sites. Main technical contents: 1. After cleaning, more than 90% of the equipment and facilities within the cleaning scope of the dust removal system should be visible with the original material color of the system components. 2. The average number of residual dirt points with a diameter of 5mm to 10mm on a 100mm2 cleaning surface after three sampling should not exceed 2, and the average number of residual dirt points with a diameter of less than 5mm after three sampling should not exceed 5. 3. The water quality of the wet dust removal system should be clean, and there should be no sedimentary sludge in the tank (box). 4. The amount of residual dust particles in the air duct and exhaust stack should be less than 1.0 g/m2. 5. The determination method of the cleaning rate is to check the descaling situation by visual inspection. 6. The dust content is tested by the GB 19210-2003 gravimetric method. 7. If there are no special requirements in the environment, after the disinfection of the dust removal system, the natural bacterial removal rate should be greater than 90%, and the total bacterial and fungal count on the inner surface of the air duct should be less than 100 CFU/m2, and no pathogenic microorganisms should be detected. 8. The total bacterial and fungal count, Legionella pneumophila, and β-hemolytic streptococcus should be tested according to the testing methods in WS 394.
