Filter element made of sintered polyethylene, the external surface of the treated microporous and hydrophobic material
Filtration systems, providing greater filtering surface became of the bag filter development. So our company offers the filter elements which in comparison with the filtering sleeves have a greater filtering surface, which in turn provides a significantly higher degree of air purification to 0.2 mg/m3, depending on dust, and several times greater durability of the elements themselves (15 years). While these filter elements have a high resistance to the abrasive dust.
The polluted air through a network of pipelines from the process equipment falls into the pre-filter chamber, where the speed is reduced, and a uniform distribution of dust on the filter elements. Further, the dust-air mixture is directed into the dirty chamber of the filter, passing through which, all the dust remains on the filter elements, clean air into a chamber of pure gas, then use a fan vented outside the filtration system.
Due to the high degree of purification (the concentration at the outlet less 0.2 mg/m3), the air can be returned into the working area, allowing you to save on heating in winter. Regeneration of filter elements are formed by the time or by the value of the differential pressure between the chambers. During regeneration caught on the filter elements of dust crumbles in the bulk container, from where by means of a screw conveyor and rotary valve is unloaded.
Due to the structure of the filter elements for their recovery is enough pressure of compressed air at 4.5-5 bar to 6 bar, required for the regeneration of bag filters, which provides a power efficiency for such filters. The consumption of compressed air required for regeneration is much lower due to the fact that all the dust remains on the surface of the element and does not penetrate into the fabric structure (as in the use of bag filters). In the end, dust is more easily shed from the filter elements.
