Description
Technical field
The present invention relates to water-treatment technology fields, and in particular to a kind of water process wound membrane element based on PE.
Background technique
With the development of membrane science and technology, water treatment by membrane is as a kind of advanced, reliable technology by more and more
Applied to Practical Project.Constantly promote the water yield of membrane component, it has also become the target that people seek assiduously in the industry.
Due to intrinsic " Trade-off " effect of film, diaphragm flux is difficult to improve without limitation, i.e., can be excessively high for it
Diaphragm flux will also bring the risk of fouling.Therefore, membrane component water yield is safely and effectively promoted, tries to increase Dan Zhiyuan
The filling membrane area of part, a kind of preferably solution of can yet be regarded as.
Wound membrane element generally comprises concentrated water filter, diaphragm, pure water selvage guide and central tube.Concentrated water filter and pure water selvage guide
Structure directly affect concentrated water and produce water hydrodynamics operating condition, be thinned concentrated water filter, will lead to element pressure drop increase, cause
The uneven distribution of diaphragm load；Pure water selvage guide is thinned, then will increase back pressure, makes the reduction of diaphragm flux.And diaphragm thickness is then past
It is past to be limited by polysulfones basement membrane, it is difficult to improve.
On the other hand, existing pure water selvage guide is concave structure, i.e., selvage guide is fine and closely woven grid substrate on one side,
Another side is the weft of parallel arrangement.When weft is closeer, the supportive of selvage guide is good but transmissibility is poor；When weft is relatively dredged, lead
The transmissibility of cloth is good and supportive is poor, and this structure is usually attended to one thing and lose sight of another in terms of enabling capabilities and water transmitting ability two.
Summary of the invention
It is an object of the invention to solve, current wound membrane element water yield is low, area is small asks for the big, filling that produces water resistance
Topic provides a kind of structure design of water process wound membrane element based on PE, and to increase the filling area of element, drop low-yield water goes out
Flow resistance power improves the water yield of element.
The technical solution adopted by the present invention is that: a kind of water process wound membrane element based on PE, the element is by diaphragm, pure water
Selvage guide, concentrated water filter, central tube composition, individual described diaphragm are back and forth folded and are sealed at its edge by film bag bonded adhesives and formed
Multiple film bags, pure water selvage guide described in place mat inside each film bag, place mat concentrated water filter outside adjacent membranes bag, film bag and selvage guide, every
Net is closely rolled up together together about central tube.
Preferably, the diaphragm is the composite membrane of PE basement membrane, and with a thickness of 10-60um, the separating layer of the diaphragm is by boundary
The ultra-thin composite layer of face polymerization or surface application methods preparation.
Preferably, the pure water selvage guide can be three-decker, and upper and lower layer is fine and closely woven grid, and middle layer unidirectionally penetrates through
A plurality of weft, selvage guide section are I-shaped structure.
Preferably, the pure water selvage guide can be composed of conventional pure water selvage guide, or by conventional selvage guide and other fine and closely woven nets
Grid material is composed in any direction.
Preferably, the film bag bonded adhesives includes bi-component glue, single-component glue and double-sided adhesive.
Preferably, the film bag length (i.e. the size of film bag coiling direction) are as follows: film bag length (the i.e. film bag winding side
To size) are as follows: household membrane component use 150-350mm, industrial membrane component use 300-700mm.
The advantages and positive effects of the present invention are:
(1) membrane component filling area is big, and diaphragm bonding loss is few；
(2) producing water, to go out flow resistance power small, and water yield is high；
(3) manufacture craft is simple, can save membrane cutting and accelerate the cured heat treatment step of viscose glue, avoid to diaphragm
Damage.
