Loading machine dust collection filter cartridge coated material polyester filter element

The filter material selected is 100% fine yarn polyester coated filter material (domestic, imported PS, PUS, PET, PTFE coated polyester non-woven fabric, coated anti-static non-woven fabric, long fiber filter paper, fiber composite material, metal filter screen, synthetic fiber non-woven filter material, synthetic fiber filter material, glass fiber filter material, activated carbon filter material, imported cotton fiber, long fiber filter felt, polystyrene cotton and other materials), using wide fold folding technology, with uniform gaps. The two end caps of the filter cartridge are made of rust proof steel plates with a thickness of 0.8mm or more and stamped (not easily deformed). The bonding between the end caps and the filter material is made of special polyurethane foam adhesive (ensuring a tight and seamless connection between the end caps and the filter material). Both the internal and external support and protection skeletons are made of galvanized steel plates with a strength of 0.8mm or above and high porosity. The strong support can prevent the filter cartridge from blowing, exploding, and collapsing. The automatic spiral casting glue fixing technology used for the inner and outer protective nets and internal filter materials ensures that the processing air volume and filtration area of the filter cartridge are uniform, making it easy for the electromagnetic pulse valve to blow back and clean the dust. It has the characteristics of acid and alkali resistance, high temperature resistance, corrosion resistance, large filtration area, high filtration efficiency, low operating resistance, high breathability, high strength, high tensile strength, and can be repeatedly washed with waterThe filter element is compact and easy to install, especially suitable for industries with high dust concentration. It belongs to the surface filter element and has the characteristics of high capture rate, low resistance, and easy sampling in the flue. It is widely used for sampling pollutants such as particulate matter, catering industry oil fume, asphalt smoke, chromic acid mist, etc. According to the material, it can be divided into two types: fiberglass filter cartridges and corundum filter cartridges. Fiberglass filter cartridges are widely used in daily life. The common filter media for filter cartridges include wood pulp fiber filter paper and spunbond polyester fiber non-woven fabric. The polyester non-woven fabric can be coated with film, oil and water, and anti-static treatmentAfter the dust containing gas enters the dust collector hopper, due to the sudden expansion of the airflow section, some of the coarse dust particles in the airflow settle under the action of gravity and inertia. The fine and low-density dust particles enter the filter chamber and are deposited on the surface of the filter material through a combination of Brownian diffusion and screening effects. The purified gas enters the clean air chamber and is discharged through the exhaust pipe. The resistance of the filter cartridge dust collector increases with the thickness of the dust layer on the surface of the filter material. When the resistance reaches a certain specified value, dust cleaning is carried out, and the pulse controller controls the opening and closing of the electromagnetic pulse valve. When the pulse valve is opened, the compressed air in the air bag is sprayed through the small hole on the spray pipe through the pulse valve to form a high-speed and high-pressure injection airflow, thereby forming an induced defect flow equivalent to 1-2 times the volume of the injection airflow, which enters the filter cartridge together, causing instantaneous positive pressure and swelling and micro movement inside the filter cartridge. The dust deposited on the filter material falls off and falls into the ash hopper. The dust in the ash hopper is continuously discharged through the unloader. Due to the low voltage pulse cleaning function of this equipment, the spraying time should be appropriately extended and the spraying interval and cycle should be appropriately shortened based on the resistance of the equipmentLoading machine dust collection filter cartridge coated material polyester filter element
