New pattern board-frame structure ultra-filter and reverse osmosis device used in cleanly production

Abstract

A CLB-X super filter and a FSB-X reverse osmosis device for clean production. A porous board formed by die pressing glass-fibre strengthened resin, synthetic fiber fabric, membrane and a baffle of water paths are superposed to fasten bolt and compose the rectangular super filter and the reverse osmosis device. Although it is similar to the regular frame in assembly, the new water processing device has a stable configuration and a high-density surface area, can endure high pressure. For the water flow state, the device could effectively prevent film pollution, improve the water flux. It simplifies the configuration of membrane units and processing, thus saves production cost. The flow of super filter (reverse osmosis) and membrane units of the invention are seen the drawing of the abstract.

Description

1. Technical field: [0001] The patented technical solution of the invention belongs to the technical field of membrane separation. 2. Background technology [0002] As a new water treatment method, ultrafiltration and reverse osmosis technology, compared with conventional water treatment methods, has no phase change in the separation process, can selectively separate solutes in the solution, and has simple equipment, wide application range, high treatment efficiency, The characteristics of low energy consumption, easy operation and control, etc., are being paid more and more attention by people and are being developed day by day. [0003] At present, the commonly used membrane modules in the industry mainly include five types: plate and frame type, garden tube type, spiral wound type, hollow fiber type and capillary type. Due to the complex composition of industrial wastewater, high content of water-soluble and suspended solids, or some colloidal substances, the types that ...

AI Technical Summary

Problems solved by technology

[0005] At present, most industrial plate and frame modules are made of stainless steel. Although they have advantages in reliability, solvent resistance, high temperature and high pressure, they are more expensive, and their cost is almost the same as that of spiral wound modules. 10 times of (production cost is 200-300 USD / m 2 , the sales price is usually 2-5 times the production cost)

Tubular membrane module, due to its complex manufacturing process, its production cost is also relatively high among all kinds of membrane modules (100-200 US dollars / m 2 )

Therefore, although industrial applications have already been realized in foreign countries, they have not been widely used in various fields of industrial production [5]
