Description
Technical field
The invention belongs to Spiral-wound membrane technology fields, and in particular to a kind of pollution-resistant rolled film water conservancy diversion filter.
Background technique
With the development of film science and technology, application of membrane field is more and more extensive, and application field is gradually deep into drink
With the multiple fields such as water, boiler feedwater, medicine, food, bitter desalination and Industrial Wastewater Treatment, especially rolling membrane element
Part, since its compact design, cheap price make it occupy most of market share.But due to the complicated component of stoste
And the impurity such as suspended matter and colloid are usually contained, therefore stoste is needed by stringent pretreatment, and nonetheless, the stream of rolled film
Road is still easy blocking, and membrane pressure difference is caused to increase, and flux decline may also cause irreversible pollution to destroy when serious.Therefore
To make rolled film further adapt to the application field of diversification, needs to improve the resistance tocrocking of membrane component, extends membrane component use
Service life.Other than improving diaphragm self performance, the design of the component of wound membrane element is mainly reflected in water supply and leads compared to more important
In the selection for flowing filter, thickness, twine spacing, immersion angle degree including water supply conductance stream filter, shape of filter twine etc.
Design.
The design of filter is concentrated mainly in the shape and arrangement of filter twine in the prior art, such as CN202725044U
Disclosed a kind of wide runner flow-guiding screen, including the longitudinal longitudinal rib arranged in parallel of plural item, by plural item between adjacent longitudinal rib
Horizontal bar connects, and longitudinal runner is formed between adjacent longitudinal rib, the cross section dimension triangle or isosceles trapezoid of longitudinal rib are lateral
Muscle is connected to the middle part of triangle or isosceles trapezoid, not with not this contact, to improve the effective use area of film and make water flow
Movable property gives birth to turbulent flow.But the position that the triangle of the patent or isosceles trapezoid are contacted with film surface is more sharp, be easy in operation because
Friction causes to be seriously worn to film surface, and the contact surface of longitudinal rib and film not instead of point contact, and face contact, contact surface is larger,
Also it be easy to cause the accumulation of suspended matter and colloid near contact surface.CN205550049U discloses a kind of circumferential wide runner rolling
Membrane module, producing water water conservancy diversion filter includes lateral rib, lengthways of rod, further includes a plurality of bending fold in corrugated shape structure
Vertical rib.Lateral rib connect to form interface point in a crisscross manner with lengthways of rod, the bending end of each vertical rib wherein side
It respectively corresponds and is connected with each interface point, form the production water flow passage of Delta Region.The utility model is to the runner filter for producing water side
It designs, increases the cross section of fluid channel product for producing water, drop the resistance to water-flow of low-yield water.But the main heap of pollutant of rolled film retention
Product does not solve influent side membrane pollution problem in influent side, the improvement for producing water side filter.
Summary of the invention
It is an object of the invention to overcome prior art defect, a kind of pollution-resistant rolled film water conservancy diversion filter is provided.
The specific technical solution of the present invention is as follows:
A kind of pollution-resistant rolled film water conservancy diversion filter, between adjacent two diaphragm of rolled film, including several longitudinal ribs

Spacing between flexible filaments band and lateral rib is 2~10mm.
In a preferred embodiment of the invention, the lateral rib connects in the adjacent peaks and troughs
Portion.
In a preferred embodiment of the invention, the lateral flexibility silk ribbon connects the adjacent peaks and troughs
Middle part.
In a preferred embodiment of the invention, the lateral flexibility between the middle part of the adjacent peaks and troughs
The length of silk ribbon is 6~23mm.
The beneficial effects of the present invention are:
1, pollution-resistant rolled film water conservancy diversion filter of the invention, compared with traditional diamond shape filter or rectangle filter, selection
Difference, for traditional filter using hard rib, the position that rib is contacted with film surface is easy to produce filtering dead angle, leads to fouling membrane
Aggravation.The present invention retains hard lengthways of rod, reduces part hard transverse direction rib and increases the hard of flexible filaments band substitution parts of traditional
Matter rib, and allow silk ribbon there are redundant lengths, under the conditions of current scour, lateral flexibility silk ribbon generates shake, on the one hand aggravates
Water flow turbulence improves mass-transfer efficiency, increases membrane flux;Film surface is cleaned in the shake of another aspect flexible filaments band, can will be attached to film
The pollutant scouring on surface is patted, and the antifouling property of film is greatly improved.
2, pollution-resistant rolled film water conservancy diversion filter of the invention, lengthways of rod extension wave-shaped, peaks and troughs position
It sets and is contacted with film surface, contact point area is small, not will cause filtering dead angle, and the contact position with upper and lower film surface is entirely that point connects
Touching, contact area is very small, and membrane pollution problem caused by filtering dead angle is eliminated compared with traditional filter.
