The function of self-cleaning air filter and the process
A large amount of dust and smoke are generated in the industrial production process. In order to prevent the dust and smoke from affecting the workshop, purifier equipment or self-cleaning air filtration equipment is installed, which can deal with the dust and smoke in time, which has a great impact on the workshop environment. The role of protection. When we buy air filter equipment, we must first understand the equipment, know what functions the air filter equipment has, and know how to filter and self-clean the equipment, so that the equipment can play a role after it is installed. So, how does the self-cleaning air filter function and the process of filtering and self-cleaning operate? Air filter filtration process: dust-laden air is sucked by the air compressor and sucked from the primary coarse filter box. After the high-efficiency filter cartridge, due to the combined effects of gravity inertia, diffusion and contact retention, the dust is adsorbed on the high-efficiency filter cartridge , The self-cleaning air enters the venturi through the sealing gasket, merges into the air collecting port in the clean air chamber, and is sucked by the air compressor from the clean air outlet pipe.
Equipment self-cleaning process: After the dust-containing air is filtered, the dust is adsorbed on the high-efficiency filter cartridge, and the PLC will perform the back-blowing self-cleaning process according to the set time sequence. When the resistance value exceeds 600 Pa, the PLC will perform the differential pressure sequence Control the back-blowing and self-cleaning process (the back-blowing time is 0.1-0.2 seconds), other high-efficiency filter cartridges work as usual, and the dust is self-cleaned by back-blowing.
The main function of the self-cleaning air filter is to grind and crush the dust, which is also called a dust collector in the industry. For example, the dust collection after grinding of lithium battery cathode materials, graphene materials, pharmaceutical grinding, grain flour, etc. is usually called a powder collector. Because the filter cartridge filter material is a pleated structure, and the cloth bag filter material is a smooth structure, under the same space conditions, the pleated structure has a larger filtering area than the smooth structure. The unfolded area of a filter cartridge is equal to the sum of the unfolded areas of multiple bags .
Self-cleaning air filter is an indispensable device on the pipeline of conveying medium. It is usually installed at the inlet of pressure reducing valve, pressure relief valve, fixed water level valve or other equipment to eliminate impurities in the medium to protect the valve. And the normal use of equipment. When the fluid enters the filter cartridge with a certain filter screen, its impurities are blocked, and the clean filtrate is discharged from the filter outlet. When cleaning is required, just take out the detachable filter cartridge and reload it after treatment. Yes, so it is extremely convenient to use and maintain.
