Example Embodiment

[0019] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0020] Such as figure 1 As shown, a fan-shaped rotary membrane separation device includes a central water collection pipe 11, an upper tray 13 and a lower tray 14. One end of the central water collection pipe 11 is provided with a transmission gear 16, and the upper tray 13 and the lower tray 14 are arranged There are a plurality of turntables 17, and the turntable 17 is composed of at least six fan-shaped membrane modules 12. The fan-shaped membrane modules are preferably 3-12 pieces of the fan-shaped membrane modules 12. There are water collection pipes 120 on both sides and inside of the fan-shaped membrane modules 12. Filled with hollow fiber membrane filaments 121; a water outlet 123 is provided on the inner side of the fan-shaped membrane module 12, and the water outlet 123 is connected to the central water collection pipe 11, and the outer side of the fa...

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...
