Separating and filtering membrane column

Abstract

The invention discloses a separating and filtering membrane column. The separating and filtering membrane column comprises a hollow cylindrical pressure-bearing shell, at least two guide discs and at least one diaphragm are arranged in the pressure-bearing shell, a central pull rod is also arranged at the middle positions of the guide disc and the diaphragm for fixation, a stacking plate, a fluid reserving disc and a flange plate are arranged at each of the upper end and the lower end of the pressure-bearing shell from inside to outside symmetrically, the flange plates seal the upper end and the lower end of the pressure-bearing shell, and an outer pull rod for tensioning the flange plate on the pressure-bearing shell is also arranged on the flange plate. According to the separating and filtering membrane column, the pressure loss is further reduced, the sewage purifying efficiency is improved, the using effect is also improved, good market recognition is achieved, industrial development is promoted and the competitive capacity of enterprises is improved.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a separation and filtration membrane column used in sewage treatment. Background technique [0002] Although the traditional spiral-wound membrane has a high filling area density, the system application has high requirements on the influent water quality and complicated pretreatment conditions. Because the organic pollutants, inorganic scaling substances and suspended particle impurities in the high-concentration fluid will easily block the screen of the membrane column, resulting in frequent shutdown and cleaning of the system, which will reduce the life of the membrane column and even fail to operate normally. [0003] The existing disc-type membrane column solves the above-mentioned anti-pollution problem of the membrane column. In fact, there is still a special problem with the disc membrane column, which is that the disc membrane column used for nanofiltration, ultrafiltration ...

AI Technical Summary

Problems solved by technology

However, in actual use, the use effect of the disc-type membrane module is still difficult to meet the actual requirements, and there is still a lot of room for improvement in its pressure loss, so it is necessary to improve the disc-type membrane module so that it has Better use effect, further improve its use effect, so that it can be better recognized by the market
