Grid type membrane module with glass fiber braided tube

Abstract

The invention discloses a grid type membrane module with a glass fiber braided tube, which consists of a coated or cured glass fiber braided tube, water collecting pipes at two ends, a water collecting pipe in the middle, a membrane pipe hoop and a water collecting vertical pipe. The grid type membrane module is characterized in that: the coated or cured glass fiber braided tube is braided by using a glass fiber yarn material, a surface curing material is silica gel, and a surface coating material is a polymer organic material; and the coated or cured glass fiber braided tube is correspondingly fixed on a small water collecting terminal of the water collecting pipe through the membrane pipe hoop or binding, and can be mounted and replaced by using a single filament. The grid type membrane module with the glass fiber braided tube is manufactured by connecting one or more membrane fragments; membrane module sludge cannot be silt up between the membrane modules and between membrane yarns; and the grid type membrane module has the advantages of large membrane flux, corrosion-resistant material, reasonable structure, high mechanical strength, easy mounting, simple replacement, and low manufacturing cost and running cost.

Description

technical field [0001] The invention belongs to the technical field of application of membrane separation technology, and in particular relates to a glass fiber braided pipe-grid membrane module. Background technique [0002] Membrane bioreactor (membrane bioreactor, MBR) has become a kind of sewage treatment and sewage recycling technology that the world pays attention to. In the past 40 years, the research and application of MBR have developed rapidly, especially in the past 10-15 years, the number of articles related to MBR at home and abroad has increased linearly, the number and scale of application projects have continued to expand, and sewage treatment projects of 10,000 to 100,000 tons / day have emerged continuously . However, membrane fouling, high energy consumption, and high cost of membrane components and replacement have always restricted the large-scale application of this process. Membrane module is a key part of the membrane unit in the membrane bioreactor s...

Problems solved by technology

[0003] This application addresses the application and manufacturing problems of hollow fiber membrane modules in the past, such as: uneven distribution of membrane flux in the length direction of membrane filaments, clogging of sludge layer between membrane filaments caused by membrane fouling, low strength of membrane modules, high cost, and Due to problems such as difficult replacement and maintenance, and the need to replace the whole bundle of membrane modules, a glass fiber braided tube-grid membrane module was proposed.
