Description
Technical field
The present invention relates to a kind of lateral flow type reverse-osmosis membrane element.
Background technology
The common application form of reverse osmosis technology in water treatment is to make spiral wound reverse-osmosis membrane element, claim again coiled reverse osmosis membrane element, its inside has one with the central tube in a plurality of holes and twists in alternately laminated multilayer reverse osmosis membrane and the flow-guiding screen on central tube.It generally has a columniform pressure vessel as housing, and central tube is connected by connector with housing two ends.
Fig. 1 is according to the schematic diagram of the profile of a kind of lateral flow type reverse-osmosis membrane element of the prior art.As shown in Figure 1, in the housing 11 of lateral flow type reverse-osmosis membrane element, there is central tube 12, in use, former water enters housing from housing two ends, the effect of passing through reverse osmosis membrane in the effect next part of pressure forms the lower water of concentration, after entering central tube, from central tube one or both ends, flow out, this part water can be called product water or fresh water; Another part flows out from housing side, can be called waste water or dense water.This lateral flow type reverse-osmosis membrane element needs four intake-outlets, and water route is comparatively complicated.
Summary of the invention
In view of this, the invention provides a kind of lateral flow type reverse-osmosis membrane element, it has comparatively simple water route.For achieving the above object, the invention provides following technical scheme:
A lateral flow type reverse-osmosis membrane element, the side of described lateral flow type reverse-osmosis membrane element is delivery port, one end is water inlet; Or side is water inlet, one end is delivery port.
Alternatively, between the flow-guiding screen of described reverse-osmosis membrane element and reverse osmosis membrane, scribble adhesive waterproof tape, the position of this adhesive waterproof tape comprises: the flow-guiding screen of described reverse-osmosis membrane element and reverse osmosis membrane are under the state launching, in one group of opposite side parallel with rolling direction, article one, opposite side is whole, and second opposite side rolls a position of initiating terminal to close from rolling end; Second opposite side is from rolling end near rolling a position of initiating terminal as described water inlet, and the side of described reverse-osmosis membrane element is delivery port; Or second opposite side is from rolling end near rolling a position of initiating terminal as described delivery port, the side of described reverse-osmosis membrane element is water inlet.
Alternatively, near described article one opposite side and near described in roll the position of initiating terminal, also scribble one section of adhesive tape, this section of adhesive tape is basically parallel to described article one opposite side.
Alternatively, the length range of described one section of adhesive tape is that described article one is to 15% of edge lengths to 25%.
According to technical scheme of the present invention, reverse-osmosis membrane element only has a water inlet, and institute is simple by water, easy for installation, and has retained the various advantages of lateral flow type reverse-osmosis membrane element, such as rolling easily, film surface velocity is large etc.Film surface velocity is conducive to greatly the deposit on fluid scouring film surface and discharges from waste water mouth, thereby is not easy to occur dirty blocking up, the life-span that is conducive to improve membrane component.In addition, in reverse-osmosis membrane element, also include for improving the adhesive tape of local surfaces mobility, reverse osmosis membrane can be fully utilized.

The specific embodiment
Below in conjunction with accompanying drawing, one exemplary embodiment of the present invention is explained, comprising the various details of the embodiment of the present invention, to help understanding, they should be thought to be only exemplary.Therefore, those of ordinary skills will be appreciated that, can make various changes and modification to the embodiments described herein, and can not deviate from scope and spirit of the present invention.Equally, for clarity and conciseness, in following description, omitted the description to known function and structure.
In the present embodiment, between the flow-guiding screen of reverse-osmosis membrane element and reverse osmosis membrane, scribble adhesive waterproof tape (being designated hereinafter simply as " adhesive tape ").Adhesive tape can be coated on flow-guiding screen, then bonding with reverse osmosis membrane, on the contrary also can.Fig. 2 is according to the schematic diagram of a kind of mode of the coated tape of the embodiment of the present invention.
As shown in Figure 2, the flow-guiding screen 20 of deployed condition is rectangular, and one end is fixed with central tube 21.Central tube 21 is positioned at the initiating terminal that rolls of flow-guiding screen, rolls direction and is the direction from left to right in figure, as shown in arrow 24.The one group opposite side parallel with rolling direction is 22He limit, limit 23.Limit 22 whole,, from rolling initiating terminal to rolling the i.e. limit 25 parallel with central tube 21 of end, scribble adhesive waterproof tape (as shown in thick black line).The part on limit 23 scribbles adhesive waterproof tape 231, and a part 232 for painting water-proof adhesive band is not as the delivery port that rolls and complete the reverse-osmosis membrane element obtaining after follow-up conventional operation.The profile of this reverse-osmosis membrane element as shown in Figure 3.
Fig. 3 is the schematic diagram with the lateral inflow reverse-osmosis membrane element of adhesive waterproof tape according to the inside of the embodiment of the present invention.Wherein show delivery port 31 and water inlet 32.In fact, delivery port 31 is corresponding to a part 232 for the not painting water-proof adhesive band in Fig. 2, and water inlet 32 is corresponding to the limit 25 in Fig. 2.
Fig. 4 is the schematic diagram with the side water outlet reverse-osmosis membrane element of adhesive waterproof tape according to the inside of the embodiment of the present invention.Wherein show delivery port 41 and water inlet 42.In fact, water inlet 42 is corresponding to a part 232 for the not painting water-proof adhesive band in Fig. 2, and delivery port 41 is corresponding to the limit 25 in Fig. 2.
From Fig. 3 and Fig. 4, can find out, this reverse-osmosis membrane element only has three water in-out ports, and institute is simple by water, easy for installation, and has retained the various advantages of lateral flow type reverse-osmosis membrane element, such as rolling easily, film surface velocity is large etc.Film surface velocity is conducive to greatly the deposit on fluid scouring film surface and discharges from waste water mouth, thereby is not easy to occur dirty blocking up, the life-span that is conducive to improve membrane component.
But it can also be seen that from Fig. 2, the crossing intersection point near zone 26 of limit 22 and central tube 21 is difficult for having fluid to flow through, so the reverse osmosis membrane of this position can not play a role, and that is to say and wasted a part of reverse osmosis membrane.In order to change this situation, in the present embodiment, in region 26, scribble adhesive waterproof tape 27, to increase near the surface mobility in region 26, making has fluid to flow through herein.The length of adhesive waterproof tape 27 can be 15% to 25% of limit 22 length.
The above-mentioned specific embodiment, does not form limiting the scope of the invention.Those skilled in the art should be understood that, depend on designing requirement and other factors, various modifications, combination, sub-portfolio can occur and substitute.Any modification of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection domain of the present invention.
