Dust-laden gas must be subjected to drying pretreatment and incorporated into the forthcoming "Technical Code for Cement Industry Dust Removal Project"

Recently, the "Technical Code for Cement Industry Dust Removal Project" edited by China National Building Material Corporation Hefei Cement Research and Design Institute has been submitted to the State Environmental Protection Administration for approval by the China Environmental Protection Industry Association. It is reported that the specification is based on relevant laws, regulations and industrial policies in China, combined with the current situation and development trend of production technology and equipment in the cement industry, and the technical level and development trend of dust removal equipment. The content relates to the overall design and pretreatment of the cement dust removal industry in China. Bag filter, electrostatic precipitator, engineering supporting facilities, fugitive emission requirements, environmental protection and safety and health, construction and acceptance, operation and maintenance, etc., applicable to the new, reconstructed and extended dust removal project of the cement industry from design to Acceptance and operation of the whole process management and operation management of the existing dust removal project can be used as the technical basis for environmental impact assessment, design, construction, environmental protection acceptance, and operation and management after completion.
In the section on pretreatment of precipitators, it is proposed that preconditions should be set in accordance with economic principles to ensure that the precipitator system meets the discharge standards. The preheating technology is used as one of the pretreatment technologies to specify the kiln head and the kiln tail. Dust-laden gas should be preferentially used for waste heat power generation and drying raw materials, fuel pretreatment.
