Fan-shaped rotary film separation device

Abstract

The invention discloses a fan-shaped rotary film separation device which comprises a central water-collecting pipe, an upper tray and a lower tray, wherein a transmission gear is arranged at one end of the central water-collecting pipe; the fan-shaped rotary film separation device is characterized in that multiple turntables are distributed between the upper tray and the lower tray, each turntable consists of at least three fan-shaped film components; water collecting pipes are arranged on two sides and the inner sides of the fan-shaped film components; hollow fiber film filaments are filled in the fan-shaped film components; water outlets are formed in the inner sides of the fan-shaped film components; the water outlets are connected with the central water-collecting pipe; fixing holes are formed in the outer sides of the fan-shaped film components; multiple fixing posts are arranged on the outer circumferences of the upper tray and the lower tray; the fixing holes are fixedly formed in the fixing posts. Compared with other rotary film devices, the fan-shaped rotary film separation device has the advantages of high filling density, high filtration flux and the like; moreover, a film is conveniently replaced, and the aim of replacing the film can be fulfilled by replacing a fan-shaped film components only.

Description

technical field [0001] The invention relates to the field of membrane separation, in particular to a fan-shaped rotary membrane separation device. Background technique [0002] Membrane separation technology is recognized as one of the most important new technologies in the 21st century. Membrane separation technology mainly includes microfiltration, ultrafiltration, nanofiltration and reverse osmosis, which are widely used in food, medicine, industrial wastewater treatment, ultrapure water preparation and biotechnology industry and other industries. Among them, hollow fiber membranes are widely used in filtration or dialysis in various fields such as industrial and municipal sewage treatment, drinking water purification, reclaimed water reuse, food processing and biomedicine. However, existing hollow fiber membranes (generally ultrafiltration membranes) have disadvantages such as easy fouling and difficult cleaning. [0003] At present, some rotary membrane separation...

AI Technical Summary

Problems solved by technology

The disadvantages of the above-mentioned rotary membrane separation device mainly include: 1) The membranes filled in the membrane equipment are all flat membranes, which have the disadvantages of low packing density, small filtration flux and easy clogging; 2) The flat membranes are all installed in one piece, It has disadvantages such as troublesome installation; 3) If one part of the diaphragm is damaged, the entire diaphragm needs to be replaced, which virtually increases the production cost of the enterprise
