Hollow fiber desalination membrane assembly and equipment

Abstract

The invention relates to the technical field of membranes and particularly relates to a hollow fiber desalination membrane assembly and equipment. The hollow fiber desalination membrane assembly comprises a pressure container and a desalination membrane unit arranged in the pressure container, wherein a raw water inlet and a concentrated water outlet are arranged in the pressure container; the desalination membrane unit comprises a membrane shell and a desalination membrane assembly arranged in the membrane shell; the desalination membrane assembly comprises a central water-producing pipe, a central water inlet pipe arranged around the peripheral side of the central water-producing pipe, a plurality of desalination membrane filaments arranged at the peripheral side of the central water inlet pipe, a water inlet end fixing layer and a water-producing end fixing layer; the water inlet end fixing layer and the water-producing end fixing layer are used for being fixed at two ends of the desalination membrane filaments respectively. The hollow fiber desalination membrane assembly and equipment disclosed by the invention has relatively high anti-pollution capacity and relatively long service life, is low in replacement cost, stable in water yield and excellent in water quality, can work in a relatively bad water quality condition and is suitable for pretreatment of a large reverse osmosis desalination system.

Description

technical field [0001] The invention relates to the field of membrane technology, in particular to a hollow fiber desalination membrane module and equipment. Background technique [0002] Membrane desalination technology has become the most widely used desalination treatment technology, which has the following advantages: 1. There is no phase change, and there is no need to heat the water quality and use instruments during the actual operation, which simplifies the operation steps and enhances the actual operation. use value. 2. Less energy consumption. 3. Small footprint, simple operation and strong adaptability. 4. No pollution to the environment, the separation process is physical separation and will not pollute the environment. Based on the above advantages, membrane desalination technology has been widely used in seawater desalination, industrial wastewater treatment and reuse, pharmaceutical pure water preparation and other fields. [0003] At present, the main des...
