Dust bag; Cleaning:
1. Dust cleaning: High frequency vibration is used to minimize larger dust particles entering the filter bag wall, without affecting the entanglement fastness of fibers, and to maintain good peel resistance of the filter bag.
2. Chemical experiment processing: Extract bag samples, use instrument analysis to detect the composition of oil stains on filter bags, select appropriate washing materials, and thoroughly clean the filter bags without causing any damage.
3. Cleaning: Select suitable washing materials and strictly mix them, clean with low-temperature water, ensure even water flow, moderate strength, and no mechanical damage to the filter bag.
4. Drying: Using hot air at around 110 ℃ to dry, maintain the dimensional stability of the filter bag, and prevent deformation and shrinkage of the filter bag after drying.
5. High reuse rate for damaged filter bags caused by abrasion, holes, etc. due to use.
Testing: Physical indicators of the cleaned dust bag are tested using instruments to ensure that the cleaning quality meets the requirements. After the above processes of processing and cleaning, the filter bag can meet the requirements for use. The effectiveness of dust removal bags is related to various factors, but mainly depends on the filter material. The filter material for dust removal bag is a cloth or felt woven from synthetic fibers, fibers, or glass fibers. Sew the cloth or felt into cylindrical or flat filter bags as needed. Select filter media suitable for the application conditions based on the properties of the flue gas. Usually, when the flue gas temperature is below 120 ℃ and acid resistance is required for the dust removal bag, polyester velvet cloth and polyester needle punched felt are often used; When dealing with high-temperature flue gas (
