Problems solved by technology
[0004] This application aims at the problems of the manufacturing method of the glass fiber braided tube curtain type dynamic membrane module in the past. The glue will flow into the glass fiber braided pipe and block the glass fiber braided pipe. The glue is easy to form pinhole gaps between the glass fiber braided pipes, and the quality is difficult to guarantee, and it is difficult to manufacture on an industrial scale. A dynamic glass fiber braided pipe is proposed. Membrane module structure and processing method

The invention provides a glass fiber braided tube dynamic membrane component. The component mainly comprises a glass fiber tube, a terminal platform (comprising a terminal), a collector pipe and so on, and is characterized in that the glass fiber tube is made from an inorganic tube-type material and has high mechanical strength and lower cost; the terminal platform has large filling area, makes full use of space, and can effectively increase the filtration area of a single membrane component; the terminal is of a hollow tubular truncated cone structure; therefore, when the glass fiber tube is sleeved on the terminal and is tightly adhered to the terminal, a gap is not easy to form; and the collector pipe is used for collecting water discharged from the glass fiber tube, and is convenient for embedding and sticking the terminal platform. The glass fiber braided tube dynamic membrane component has the characteristics of simple manufacture, convenient industrial production, high mechanical strength, lower cost, long service life and stable water discharge.
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 tube curtain type dynamic membrane module. Background technique [0002] The membrane module is a key part of the membrane unit in the membrane bioreactor sewage treatment process, which has a decisive impact on the effluent water quality. Conventional curtain membrane modules used for sewage treatment in engineering are mainly made by casting and bonding membrane filaments into water collection pipes. Conventional organic membranes have the problems of broken filaments, high cost, and easy membrane pollution. For this reason, dynamic membranes and membrane modules have become a research hotspot. For this reason, this patent proposes a glass fiber braided pipe curtain type dynamic membrane module. The glass fiber braided tube dynamic membrane module is made of glass fiber braided tube, which has low cost, h...
