Enhanced external pressing hollow fibrous membrane assembly easy to assemble and capable of being integrated

Abstract

The invention relates to an enhanced external pressing hollow fibrous membrane assembly easy to assemble and capable of being integrated. The enhanced external pressing hollow fibrous membrane assembly is characterized by comprising at least one membrane assembly and two water collecting devices; the membrane assembly is formed by a plurality of hollow fibrous membranes and two membrane sealing containers; the water collecting device is a columnar casing which has a columnar hollow cavity, the columnar hollow cavity forms a water passage, a first pipe joint is arranged at the top of the casing, a second pipe joint matched with the first pipe joint is arranged at the bottom of the casing, and a membrane assembly insertion hole is arranged in the side wall of the casing; in an assembly state, the two water collecting devices and the membrane assembly insertion hole are arranged face to face, the two membrane sealing containers in each membrane assembly are correspondingly inserted into the membrane assembly insertion holes of the two water collecting devices, and hollow pipe cavities of hollow fibrous membranes in the membrane assembly are communicated with the columnar hollow cavities of the water collecting devices. According to the invention, the number of needed membrane assemblies can be flexibly adjusted according to water quality and water volume, and membrane filaments are not easy to damage in assembly, thereby being firm and durable.

Description

technical field [0001] The invention belongs to purification equipment in the field of water treatment, and in particular relates to an easily assembled and integrated enhanced external pressure hollow fiber membrane module. The external pressure hollow fiber membrane treatment system composed of the membrane module is especially suitable for suspended solids, turbidity, microorganisms and Surface water with large changes in oil and other indicators is used as influent drinking water in the water production process. Background technique [0002] Due to environmental pollution and water shortage in today's world, the rapid development of water treatment technology is forced. Due to the many advantages of hollow fiber membrane technology (including larger filtration area, easier reverse cleaning and lower cost, etc.), it is widely used in water supply treatment, sewage treatment and reclaimed water reuse. [0003] The structure of the hollow fiber membrane in the hollow fiber...

AI Technical Summary

Problems solved by technology

[0007] Whether the external pressure hollow fiber membrane module using reinforced external pressure membrane filaments can be integrated and easy to assemble is very important, because this will affect the adaptability of the hollow fiber membrane system to different water quality and water inflow (that is, the impact resistance) , In addition, if the membrane module is not easy to assemble, it is easy to damage the membrane filament during assembly, thereby reducing the service life of the membrane module and the membrane treatment system
