Abstract
The invention relates to a spiral wound film element, which comprises a central water collecting pipe, sealant, a separation diaphragm, water producing guide cloth and water inlet guide cloth. The spiral wound film element uses multi-folding of the integral separation diaphragm to form a plurality of film blades so as to enlarge the effective film area of the film element, reduce the use of the sealant and achieve the aims of increasing the water yield and reducing the cost.
Description
Technical field
The present invention relates to purifier, relate in particular to a kind of filter of purifier, relate in particular to a kind of a kind of spiral wound film element of filter.
Background technology
At present, spiral wound film element commonly used is to be used for the common diffusion barrier of fluid separation field, comprise reverse osmosis membrane, NF membrane, milipore filter, micro-filtration membrane, electrodialytic membranes, infiltration vaporization membrane or the like, the stalling characteristic that they utilize Separation membrane itself to have, remove in the fluid certain or multiple material, reach purposes such as purifications, concentrated, purification.
Common separating film element mainly is made of Separation membrane, product water flow-guiding cloth, water inlet flow-guiding cloth, center collector pipe and sealing glue; When producing according to dimensional requirement, required raw material have been cut, Separation membrane is cut into several pages (not waiting from 2 pages to 100 pages), to seal except that other three directions with sealing glue then with the center collector pipe contacts an end, twist in then on the collector pipe of center, each film page or leaf all must seal on its three directions more like this, and one whole diaphragm also is cut into a plurality of film pages or leaves, each film page or leaf sealing back forms a film bag, so common spiral wound film element is a multimembrane page or leaf multimembrane bag constructions.
The above spiral wound film element of effective film area 1 square meter commonly used all adopts multimembrane page or leaf multimembrane bag constructions.Such spiral wound film element need use a lot of fluid sealants and diaphragm utilization rate and effective film area lower, and aquifer yield is not high.
Summary of the invention
Technical problem to be solved by this invention provides a kind of minimizing fluid sealant and uses, and improves the spiral wound film element that diaphragm utilization rate and effective film area and aquifer yield increase, to overcome the deficiency that prior art exists.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of spiral wound film element comprises center collector pipe, fluid sealant, Separation membrane, product water flow-guiding cloth, water inlet flow-guiding cloth, it is characterized in that:
Described Separation membrane is not for cutting diaphragm, and what folding formation was alternately arranged is a plurality of by positive water inlet interlayer that forms of Separation membrane and the product water interlayer that is formed by the Separation membrane back side;
Described water inlet flow-guiding cloth is inserted in the described water inlet interlayer, and described product water flow-guiding cloth is inserted in the described product water interlayer;
The front and back dual-side adjacent with flanging of described product water interlayer makes that by fluid sealant sealing producing water interlayer has and the flanging opening opposing, and the opening that the Separation membrane after will describedly folding is arranged to described product water interlayer contacts with the center collector pipe;
The Separation membrane back side of the described Separation membrane the superiors except that with side that the center collector pipe contacts, other three side and collector pipe surface, center are sealed by fluid sealant;
Described folding back and the Separation membrane that is inserted with water flow-guiding cloth into and produces the water flow-guiding cloth twist on the collector pipe of center.
Adopt technique scheme, because not needing to be cut into the multipage Separation membrane, Separation membrane do not form a plurality of film pages or leaves through repeatedly folding the back, when producing, only need the front and back dual-side of product water interlayer of hermetic separation diaphragm and three sides at the superiors Separation membrane back side, the single film bag of final formation, thus the utilization rate of diaphragm and the effective film area of membrane component improved, test according to reality, can improve the utilization rate 5% to 8% of diaphragm, the aquifer yield of separating film element has also increased 5% to 8%.Therefore, spiral wound film element of the present invention has the advantage that reduces the fluid sealant use, improves diaphragm utilization rate and effective film area and aquifer yield.
Description of drawings
The present invention is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an A place enlarged diagram among Fig. 1;
Fig. 3 is a B place enlarged diagram among Fig. 1.
Among the figure:
1, center collector pipe 11, infiltration hole 2, fluid sealant 3, Separation membrane 31, Separation membrane front 32, the Separation membrane back side 33, the superiors Separation membrane back side 34, side 4, produce water flow-guiding cloth 5, water inlet flow-guiding cloth 6, water inlet interlayer 7, produce water interlayer 71, flanging 72, side 73, opening
The specific embodiment
As Fig. 1 and in conjunction with Fig. 2, shown in Figure 3, spiral wound film element of the present invention comprises center collector pipe 1, fluid sealant 2, Separation membrane 3, product water flow-guiding cloth 4, water inlet flow-guiding cloth 5.
Center collector pipe 1 is a hollow tube, its infiltration hole 11 upward surperficial and internal communication.Separation membrane 3 is not for cutting diaphragm, and it is a plurality of by positive 31 water inlet interlayers 6 that form of Separation membrane and the product water interlayer 7 that formed by the Separation membrane back side 32 that folding formation is alternately arranged.Water inlet flow-guiding cloth 5 is inserted in the described water inlet interlayer 6, produces water flow-guiding cloth 4 and is inserted in the product water interlayer 7.The front and back dual-side 72 adjacent with flanging 71 that produces water interlayer 7 makes that by fluid sealant 2 sealings producing water interlayer 7 has and flanging 71 opening opposing 73, and the opening 73 that the Separation membrane 3 after folding is arranged to produce 7 layers on water folder contacts with center collector pipe 1.In addition, Separation membrane 3 the superiors Separation membrane back sides 33 except that with side that the center collector pipe contacts, other three side 34 is sealed a plurality of film pages or leaves of so final formation with center collector pipe 1 surface by fluid sealant.At last, with folding back and be inserted with water flow-guiding cloth into and produce the water flow-guiding cloth and sealing after Separation membrane twist on the center collector pipe 1.
Again as shown in Figure 2, represent that with black arrow feed water flow is to, the product current direction of representing with hollow arrow.As can be seen, water inlet is from three opening directions into water flow-guiding cloth 5 of flowing through of water inlet interlayer 6, and a part wherein is converted into product water, sees through Separation membrane 3.Because the sealed glue 2 of dual-side seals before and after producing water interlayer, produces water and can only flow to center collector pipe 1.
By above detailed introduction, the present invention utilizes the repeatedly folding of complete Separation membrane as can be seen, forms a plurality of film pages or leaves, has enlarged the effective film area of membrane component, has reduced the use of fluid sealant, has reached the increase aquifer yield, the purpose that reduces cost.
But the above-mentioned specific embodiment is exemplary, is to understand and implement the present invention in order better to enable those skilled in the art to, and can not be interpreted as it is limiting the scope of the invention.So long as any being equal to of doing based on disclosed spirit changes or modification, all fall into protection scope of the present invention.
