Dust removal principle of shot blasting machine
The dust in the shot blasting chamber is sucked into the dust collector by the centrifugal fan through the ventilation pipe. First, the larger particles are separated after settlement by the settler. The suspended dust that has not settled is sucked into the dust removal chamber. After filtering through the filter cylinder, the granular dust is adsorbed on the filter cylinder, The dust adsorbed on the filter cartridge is blown by the pressure of the pulse valve and falls into the dust collecting box.
Xinke dust collector is designed and manufactured with the latest technology of American Donatson Company, the filter material is imported new filter material. It is characterized by adhering a layer of sub-micron ultra-thin fibers to the general filter material, and the fibers of the adhesion layer are arranged very closely, and the gap is only 1% of the underlying fibers. The very small screen can block most of the sub-micron dust particles on the outer surface of the filter material, so that it cannot enter the underlying fiber. Therefore, a dust layer with good permeability is formed in the early stage to keep it low resistance and high efficiency. Because the dust can not go deep inside the filter material, it has the characteristics of low resistance and easy cleaning, and the filtration accuracy reaches 5μ. This feature is unmatched by the ordinary bag dust collector.
Therefore, the dust emission concentration is far lower than the relevant national environmental protection requirements. Dust removal efficiency up to 99.5%, dust emission concentration ≤50mg/m3. The air pipe draws air from the shot blasting room, because there is no air supply, a certain negative pressure will be formed in the shot blasting room, and dust will not escape. The dust removal system is designed with large air volume, good dust removal effect, and always keeps the cleaning room working under negative pressure to ensure that the working environment in the production process meets the relevant requirements. The dust collector is a pulse-type filter cartridge dust collector, and the dust removal efficiency is 99.9%, which meets the requirements of GB16297-1996 "Comprehensive emission standard of air pollutants" and GBJ4-73 industrial "three wastes" emission trial standard, that is, dust concentration emission standard ≤100mg/m³; The dust concentration of the work site is less than 5mg/m3, and the noise meets the requirements of JB/T8355-1996 "General Technical Conditions for shot blasting equipment", that is, the noise is less than 90dB. It is characterized by low equipment use cost and convenient maintenance. And has a good dust removal effect, so that the air containing dust can be directly discharged after dust removal, without the need for other purification equipment.
