Single-head double-end water outlet structure for column-type hollow fiber membrane

Abstract

The invention relates to a single-head double-end water outlet structure for a column-type hollow fiber membrane. The structure includes a column-type hollow fiber membrane rod, an internal-through membrane shell cover and an ordinary membrane shell cover, wherein the internal-through membrane shell cover and the ordinary membrane shell cover are respectively mounted at two ends of the column-type hollow fiber membrane rod; the two ends of the column-type hollow fiber membrane rod are connected with bearing ferrules through glue-sealing ferrules on the inner side; inner ferrules are bonded with the outer sides of the two ends of the column-type hollow fiber membrane rod; each inner ferrule is propped against the corresponding bearing ferrule, and both do not move relatively. The single-head double-end water outlet structure for the column-type hollow fiber membrane has the advantages that the customer use cost is greatly reduced, the membrane filament encapsulation efficiency is improved, the membrane filament layout is strictly uniform, the membrane filament can be mounted or dismounted, two-end water outlet of the membrane filament fully utilizes the water flux characteristics of the membrane filament, the shape and size of the membrane shell provided by the invention are the same as those of an ordinary membrane shell, so that the ordinary membrane shell can be totally replaced, and the single-head double-end water outlet structure for the column-type hollow fiber membrane can be applied to most occasions and greatly enlarge the using conditions of column-type membranes.

Description

technical field [0001] The invention relates to the field of manufacturing column fiber membrane shells, in particular to a single head and double end water outlet structure of a column type hollow fiber membrane. Background technique [0002] Hollow fiber membrane (hollow fiber membrane) looks like a fiber-like, self-supporting membrane. It is a kind of asymmetric membrane, and its dense layer can be located on the outer surface of the fiber / such as reverse osmosis membrane, or on the inner surface of the fiber (such as microfiltration membrane, nanofiltration membrane and ultrafiltration membrane). [0003] Water treatment through membrane technology is used in pharmaceutical, brewing, catering, chemical industry, municipal sewage reuse, hospital, residential sewage reuse, papermaking and other production and domestic sewage treatment. Membrane separation technology is a separation technology widely used in the separation, concentration and purification of solutions or ...

AI Technical Summary

Problems solved by technology

[0006] 1. Because the membrane filaments were not neatly arranged and each filament was fixed before, the distribution of the final membrane filaments was uneven

[0007] 2. After it is made, it cannot be disassembled and becomes a whole, and the maintenance cost is extremely high

[0008] 3. In...
