Immersion type hollow fiber membrane component and complete equipment thereof

Abstract

The invention discloses an immersion-type hollow fibrous membrane component and complete equipment thereof and belongs to the technical field of manufacturing a membrane component through water treatment. The immersion-type hollow fibrous membrane component consists of membrane silk bundles, membrane end sockets and a central supporting tube; the membrane silk bundles have at least four bundles and are distributed on the periphery of the central supporting tube; two ends of the membrane silk bundles are provided with one membrane end socket respectively, wherein one membrane end socket is a gas inlet end socket; and the other one is a water producing end socket. A plurality of membrane components can be combined into a small unit and a large unit till membrane stacks on the equipment so as to improve service life of the membrane silk and the membrane component; and the structural design of the membrane component concentrates the advantages that the prior strip curtain-type membrane component is uneasy to pollute and the prior columnar membrane component has large membrane filtering area into a whole and has the advantages of large membrane filtering area, convenient mounting of the membrane component, convenient maintenance and the like.

Description

technical field [0001] The invention discloses a submerged hollow fiber membrane module and a complete set of equipment thereof, belonging to the technical field of membrane module manufacturing for water treatment. Background technique [0002] Although there are many types of membrane modules at present, they are applied to water treatment or recycling in various fields, and generally have their own defects, such as: the membrane filtration area of ​​the curtain membrane module is small; the column membrane module is easy to be polluted. The hollow fiber membrane looks like a fiber and is a 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 and ultrafiltration membrane). Due to the deficiencies in the structure of the existing submerged hollow fiber membrane modules, there are the followi...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the support tube used to support the component is generally located around the component, the structure is complex, and the support tube of this structure only has the function of support and has a single function;

[0004] 2. Due to the unreasonable aeration method and uneven gas distribution, the local impact of the membrane filament is large, and the membrane filament is prone to damage and the service life is reduced;

[0005] 3. Membrane module installation is complicated
