one. Product Features

The fiber bundle filter is a pressure-type fiber filtration equipment with advanced structure and excellent performance. It uses polymer polypropylene fiber bundles as the filter material. The diameter of the filter material can reach tens of microns or even several microns, reaching the micron level.

Compared with the granular filter material, the fiber bundle filter material has the advantages of large specific surface area and low filtration resistance, which solves the problem that the filtration accuracy of the granular filter material is limited by the particle size of the filter material. It is an updated product of quartz sand and other particulate filter equipment.

five. working principle

The equipment is composed of fixed perforated plates, fiber bundles, movable perforated plates, and air distribution devices. One end of the fiber bundle filter material is fixed on the fixed porous plate, and the other end of the filter material is provided with a self-service adjusting device that can change the fiber density. The device is provided with a guide member to prevent jamming.

During operation, the equipment enters water from the upper part and discharges 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 to run downwards, the fiber filter layer is compressed, and its bulk density gradually increases along the direction of the water flow, so that the filter layer flows along the water. The direction of the porosity gradually decreases from larger to smaller, and the corresponding filter layer pore diameter and pores gradually decrease, thus forming a particularly ideal variable-porosity deep filtration state. The filtration process includes both horizontal deep filtration and vertical deep filtration, thereby 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 the backwash water flow and the cleaning air, the self-service fiber density adjustment device drives the fiber filter bed to move upward to stretch the fiber filter material upwards. , To achieve a loose state, through the air-water mixing cleaning technology, during the bubble gathering and water washing process, the fiber filter material is in a state of continuous shaking in the longitudinal direction, so that the fiber filter material is cleaned very thoroughly, so as to achieve the ideal cleaning effect.
