Fiber bundle filter manufacturer

Fiber bundle filter is a pressure fiber filter with advanced structure and excellent performance. It uses high molecular polypropylene fiber bundle as the filter material, and its filter material diameter can reach tens of microns or even several microns, reaching the micron level.

Compared to granular filter media, fiber bundle filter media has the advantages of larger specific surface area and lower filtration resistance, which solves the problem that the filtration accuracy of granular filter media is limited by the particle size of the filter media. It is an upgraded product of quartz sand and other granular material filtration equipment.

5、 Working principle

The equipment consists of fixed porous plates, fiber bundles, movable porous plates, gas distribution devices, etc. One end of the fiber bundle filter material is fixed on a fixed porous plate, and the other end of the filter material is equipped with a self-service adjustment device that can change the fiber density. The device is equipped with a guide component to prevent jamming.

During operation, the equipment receives water from the upper part and water from the lower part. At this time, under the action of water flow and gravity, the self-service fiber density adjustment device pushes the fiber filter bed downwards, compressing the fiber filter layer. Its packing density gradually increases along the direction of water flow, causing the porosity of the filter layer to gradually decrease from large to small along the direction of water flow. Correspondingly, the pore diameter and pore size of the filter layer gradually decrease, thus forming a particularly ideal variable pore deep filtration state. The filtration process includes both horizontal and vertical deep filtration, effectively improving the filtration accuracy.

When the filter layer is contaminated and needs to be cleaned and regenerated, the cleaning water passes through the fiber filter bed in the opposite direction. Under the action of backwash water flow and cleaning air, the self-service fiber density adjustment device drives the fiber filter bed to move upward, causing the fiber filter material to stretch upward and reach a loose state. Through the air-water mixing cleaning technology, the fiber filter material is constantly shaking longitudinally during the process of bubble aggregation and hydraulic flushing, which makes the fiber filter material thoroughly cleaned and achieves the ideal cleaning effect.
