Description

Technical Field

[0001] The invention relates to the technical field of self-cleaning filter cartridge processing, in particular to a processing technology of a self-cleaning filter cartridge for flue gas dust removal. Background Art

[0002] The filter cartridge for flue gas dust removal is an important filtering equipment, which is widely used in the field of industrial dust removal. A large amount of dust will be generated during the industrial production process. The existing filter cartridges cannot easily realize the self-cleaning function during use, and are prone to corrosion and damage during use. Static electricity is easily generated during use, making it difficult to clean up the adhered dust. In addition, the existing filter cartridge processing technology and preparation production efficiency are low, and the quality of the manufactured filter cartridges is poor. Therefore, a self-cleaning filter cartridge processing device and process for flue gas dust removal are needed to improve the above problems. Summary of the Invention

[0003] In view of the problems in the prior art, the present invention provides a processing technology for a self-cleaning filter cartridge for flue gas dust removal.

Material selection and pretreatment: Based on the specific needs of flue gas dust removal, select high-performance filter cartridge materials, such as polyester fiber, polytetrafluoroethylene (PTFE), etc. These materials should have high filtration accuracy, corrosion resistance, wear resistance and high temperature resistance. According to design requirements, the material thickness should be controlled between 0.3mm and 1.0mm. Use detergent and water to clean the material surface to remove oil and dust impurities to ensure the cleanliness of the material surface. Place the cleaned material in a drying device to ensure that there is no moisture residue on the material surface; S2. Filter cartridge structure design and manufacturing: Based on the size and performance requirements of the dust collector, select the appropriate filter cartridge diameter, which should be controlled between 100mm and 400mm. Based on the space requirements and filtration efficiency of the dust collector, select the appropriate filter cartridge length, which should be controlled between 500mm and 2000mm. Based on the filtration accuracy requirements, select the appropriate porosity, which should be controlled between 20% and 50%. Based on the design dimensions, use cutting equipment to cut the material into the appropriate shape and size. Use sewing machines and heat-sealing equipment to process the cut material into a cylindrical shape, and ensure the sealing of the sewing and heat-sealing points. S3. Coating treatment: Coating 1 uses carbon black, graphite and metal powder, which usually account for 5%-30% of the total ratio. These materials have excellent conductive properties and can effectively conduct static electricity accumulated on the surface of the filter cartridge. The resin base uses epoxy resin and polyurethane resin, which account for 30%-60% of the total ratio. The resin base provides good adhesion and film-forming properties and is the main component of the coating. The solvent is used to dilute the resin and conductive material for easy coating. The solvent ratio accounts for 10%-40% of the total. The additives use leveling agents, defoaming agents and curing agents, which account for 1%-10% of the total ratio. The additives are used to improve the construction performance and curing performance of the coating and ensure the smoothness and uniformity of the coating. Uniformity, coating 2, anti-corrosion fillers use flake graphite, ceramic microbeads, and nano-silicon carbide, accounting for 10%-40% of the total ratio. These fillers have excellent chemical stability and corrosion resistance and can block the penetration of corrosive substances. Resin base materials use phenolic resin, epoxy resin and fluororesin, accounting for 30%-60% of the total ratio. The resin base provides good corrosion resistance and adhesion. Solvents are used to dilute resins and fillers, accounting for 10%-30% of the total ratio. The choice and ratio of solvents depend on the required coating viscosity and construction conditions.
