Encapsulation method of hollow fiber membrane filter element

Abstract

A hollow fiber membrane filter element, characterized in that it includes a filter shell, a central tube, a hollow fiber membrane, a sealing shell, a sealing layer and a water collection cover, an opening is formed at the upper end of the filter shell, and a dirty water outlet hole is provided on the bottom plate; the central tube Located in the middle of the aforementioned filter housing, one end opens to form a water inlet port and the side wall is provided with a water distribution hole; the hollow fiber membrane is located in the aforementioned filter housing and the first end is evenly coated on the outer circumference of the water inlet port of the central tube, and the second end is along the Arranged along the length direction of the central tube, near the bottom end of the central tube; the sealing shell is arranged on the outer periphery of the opening of the aforementioned filter housing; the sealing layer is located between the inner wall of the aforementioned sealing shell and the hollow fiber membrane, and between the aforementioned hollow fiber membrane And between the aforementioned hollow fiber membrane and the outer wall of the central tube. The invention also discloses a glue sealing method for the hollow fiber membrane filter element. It has the advantages of more uniform water distribution and reduced concentration polarization of membrane filaments.

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
