Fiber bundle filter and method of use thereof

Abstract

The invention discloses a fiber bundle filter and a using method thereof, The fiber bundle filter comprises a container and a filter element arranged in the container; a spiral water channel is arranged in the container, and the spiral direction is perpendicular to the extending direction of fiber bundles; a water inlet pipe and a water outlet pipe are arranged in the container, and are respectively provided with openings communicated with the water channel; the openings of the water inlet pipe and the water outlet pipe are respectively arranged in both ends of the water channel in the spiral direction; at least one pair of openings is arranged at different heights, wherein the openings have equal flow and are respectively located in the water inlet pipe and the water outlet pipe. According to the fiber bundle filter, a filtering process has both the deep filtration parallel to the direction of fiber bundles and the deep filtration perpendicular to the direction of fiber bundles through the special design of the spiral water channel; the filtering precision can be improved effectively; meanwhile, the contact time of water and the fiber bundle filter element can be prolonged, and the filtering effect can be improved. In addition, the flow-equal openings in the water inlet pipe and the water outlet pipe are arranged at different heights, so as to be beneficial for ensuring the filtering area.

Description

technical field [0001] The present invention relates to a filter device and a method for its use. Background technique [0002] High-efficiency fiber bundle filter is a pressure-type fiber filter equipment with advanced structure and excellent performance. It uses a new type of bundled soft filler-fiber as the filter element. The diameter of the filter material can reach tens of microns or even several microns, and it has the advantages of large specific surface area and small filtration resistance. Filter material particle size limitation and other issues. The small diameter of the filter material greatly increases the specific surface area and surface free energy of the filter material, increases the contact opportunity between the impurity particles in the water and the filter material and the adsorption capacity of the filter material, thereby improving the filtration efficiency and pollution interception capacity. But there is following problem in existing equipment: ...

AI Technical Summary

Problems solved by technology

But there is following problem in existing equipment: promptly filter mode is single, or only have the parallel filtration that is parallel to fiber bundle direction, or only have the vertical filtration that is perpendicular to fiber bundle direction, and the residence time of water in filter is too short, therefore with fiber bundle The contact time is also too short, resulting in insufficient contact and poor filtering effect
