Technical field
The present invention relates to membrance separation field, and in particular to a kind of new organic composite tubular membrane.
Background technology
Tubular membrane generally in internal diameter 5-25mm, the glass fibre synthetic paper of length 0.3-6m, non-woven fabrics, plastics or rustless steel
Form Deng being cast on the inside of supporter.As tubular membrane can keep enough turbulent flows under relatively low operating pressure, it is therefore prevented that
Grain thing obtains accumulation in the internal layer surface of film, therefore the membranous system can be made to obtain very high Membrane Filtration Flux, while extending film
Service life.This turbulent flow, cross flow filter and big passage membrane tube, reduce the demand to pretreatment, and other membrane structures
Form is compared, and tubular membrane has bigger application and development prospect.
Traditional organic tubular type film manufacturing method typically has two kinds：
Rubbing method：Organic material is made into pipe first, then by the method shape film formation surface such as curtain coating, knifing；
Sintering process：Organic material is made into nanometer grade powder, then tubular membrane is formed by high temperature sintering.
Some self-contained being placed in plastics or stainless steel cylinder body into a branch of membrane tube of single membrane tube are positioned with suitable method
Fastening, constitutes tubular membrane component.
The defect and deficiency of prior art：With above-mentioned traditional organic tubular type film manufacturing method, the more difficult control of its preparation condition
System；In unit volume, effective membrane area is little（Filling rate is low）；The sealing of the mouth of pipe is also relatively difficult, causes tubular membrane production cost
Height, hampers the extensive application of tubular membrane.
