Hollow fiber membrane filter element and packaging method thereof

Abstract

A hollow fiber membrane filter element is characterized in that the filter element comprises a filter shell, a central pipe, hollow fiber membranes, a glue sealing shell, glue sealing layers and a water collecting cover; an opening is formed in the upper end of the filter shell, and a dirty water outlet hole is formed in a bottom plate; the central pipe is arranged in the middle of the filter shell, one end is opened to form a water inlet port, and water distribution holes are formed in the side wall; the hollow fiber membranes are positioned in the filter shell, first ends of the hollow fibermembrane uniformly coat the periphery of the water inlet port of the central pipe, and second ends of the hollow fiber membranes are arranged in the length direction of the central pipe and close tothe bottom end of the central pipe; the glue sealing shell is arranged on the periphery of the opening of the filter shell; and the glue sealing layers are positioned between the inner wall of the glue sealing shell and the hollow fiber membranes, between the hollow fiber membranes and between the hollow fiber membranes and the outer wall of the central pipe. The invention further discloses a gluesealing method for the hollow fiber membrane filter element. The method has the advantages of more uniform inlet water distribution and reduction of membrane filament concentration polarization.

Description

technical field [0001] The invention relates to a filter membrane, in particular to a packaging method for the filter membrane. Background technique [0002] Hollow fiber membrane household water purifier components generally include a filter housing and a hollow fiber membrane located in the filter housing. The hollow fiber membrane is mostly in the form of a U-shaped sealing assembly, but this method has the following problems: First, the length difference between the inside and outside of the hollow fiber membrane It is large, and there is a lot of waste in production and removal (U-shaped center and outside), which wastes resources; secondly, the U-shaped is wrapped with a mesh sleeve, so that the hollow fiber membranes are tightly bonded. Under the action of pollutants and pressure in the water, the internal hollow fiber membranes cannot be effectively Utilization; finally, the U-shape is wrapped with a mesh sleeve, so that the hollow fiber membrane is tightly bonded, t...

Under the action of pollutants and pressure in the water, the internal hollow fiber membranes cannot be effectively Utilization; finally, the U-shape is wrapped with a mesh sleeve, so that the hollow fiber membrane is tightly bonded, the filling of the hollow fiber membrane is uneven, and the flow of the external pressure hollow fiber membrane filter element is uneven, resulting in concentration polarization, which cannot effectively filter and desalinate
