According to a technical scheme provided by the invention, the reverse osmosis membrane element only has one water inlet, so the water way is simple, convenient installation is realized, and advantages of the sidestream reverse osmosis membrane element are reserved, e.g., easy rolling and a great flow velocity on a membrane surface.
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 the spiral wound reverse-osmosis membrane element, claim again coiled reverse osmosis membrane element, its inside has one with the pipe core in a plurality of holes and twists in alternately laminated multilayer reverse osmosis membrane and flow-guiding screen on the pipe core.It generally has a columniform pressurized vessel as housing, and pipe core is connected by junctor with the housing two ends.
Fig. 1 is the synoptic diagram according to 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 pipe core 12 is arranged, in use, former water enters housing from the housing two ends, the effect of passing through reverse osmosis membrane in the effect next section of pressure forms the lower water of concentration, flow out from the pipe core one or both ends after entering pipe core, this part water can be called product water or fresh water; Another part flows out from the housing side, can be called waste water or dense water.This lateral flow type reverse-osmosis membrane element needs four intake-outlets, and the 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 kind of lateral flow type reverse-osmosis membrane element, the side of described lateral flow type reverse-osmosis membrane element are water outlet, and an end is water inlet; Perhaps, the side is water inlet, and an end is water outlet.
Alternatively, scribble adhesive waterproof tape between the flow-guiding screen of described reverse-osmosis membrane element and the reverse osmosis membrane, 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 that launches, in one group of opposite side parallel with rolling direction, article one, opposite side is whole, and the second opposite side rolls the position of initiating terminal to close from rolling end; The second opposite side from roll terminal near the position that rolls initiating terminal as described water inlet, the side of described reverse-osmosis membrane element is water outlet; Perhaps, the second opposite side from roll terminal near the position that rolls initiating terminal as described water outlet, the side of described reverse-osmosis membrane element is water inlet.
Alternatively, near described article one opposite side and near the described position that rolls initiating terminal, also scribble one section adhesive tape, this section adhesive tape is basically parallel to described article one opposite side.
Alternatively, the length range of described one section adhesive tape is that described article one is to 15% to 25% of edge lengths.
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 kept the various advantages of lateral flow type reverse-osmosis membrane element, such as roll easily, the film surface velocity is large etc.The film surface velocity is conducive to greatly the settling on fluid scouring film surface and discharges from the waste water mouth, thereby it is stifled to be not easy that dirt occurs, the life-span that is conducive to improve membrane element.In addition, in reverse-osmosis membrane element, also include for the adhesive tape that improves the local surfaces flowability, reverse osmosis membrane can be fully utilized.
Description of drawings

Embodiment
Below in conjunction with accompanying drawing example embodiment of the present invention is explained, to help understanding, they should be thought it only is exemplary comprising the various details of the embodiment of the invention.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, omitted the description to known function and structure in the following description.
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 ").Can be coated in adhesive tape on the flow-guiding screen, then bonding with reverse osmosis membrane, on the contrary also can.Fig. 2 is the synoptic diagram according to a kind of mode of the coated tape of the embodiment of the invention.
As shown in Figure 2, the flow-guiding screen 20 of deployed condition is rectangular, and an end is fixed with pipe core 21.Pipe core 21 is positioned at the initiating terminal that rolls of flow-guiding screen, rolls direction and is from left to right direction among the figure, and is as shown in arrow 24.The one group opposite side parallel with rolling direction is limit 22 and limit 23.Limit 22 whole namely from rolling initiating terminal to rolling the terminal i.e. limit 25 parallel with pipe core 21, scribble adhesive waterproof tape (shown in thick black line).The part on limit 23 scribbles adhesive waterproof tape 231, and the part 232 of painting water-proof adhesive band is not as the water outlet that rolls and finish the reverse-osmosis membrane element that obtains after the follow-up conventional operation.The profile of this reverse-osmosis membrane element as shown in Figure 3.
Fig. 3 is according to the inside of the embodiment of the invention synoptic diagram with the lateral inflow reverse-osmosis membrane element of adhesive waterproof tape.Wherein show water outlet 31 and water inlet 32.In fact, namely corresponding to the part 232 of the not painting water-proof adhesive band among Fig. 2, water inlet 32 is corresponding to the limit 25 among Fig. 2 for water outlet 31.
Fig. 4 is according to the inside of the embodiment of the invention synoptic diagram with the side water outlet reverse-osmosis membrane element of adhesive waterproof tape.Wherein show water outlet 41 and water inlet 42.In fact, namely corresponding to the part 232 of the not painting water-proof adhesive band among Fig. 2, water outlet 41 is corresponding to the limit 25 among Fig. 2 for water inlet 42.
Can find out that from Fig. 3 and Fig. 4 this reverse-osmosis membrane element only has three water in-out ports, institute is simple by water, easy for installation, and has kept the various advantages of lateral flow type reverse-osmosis membrane element, such as roll easily, the film surface velocity is large etc.The film surface velocity is conducive to greatly the settling on fluid scouring film surface and discharges from the waste water mouth, thereby it is stifled to be not easy that dirt occurs, the life-span that is conducive to improve membrane element.
But it can also be seen that from Fig. 2 the intersection point near zones 26 that limit 22 and pipe core 21 intersects are difficult for having the flow mistake, so the reverse osmosis membrane of this position can not play a role, that is to say has wasted a part of reverse osmosis membrane.In order to change this situation, in the present embodiment, in zone 26, scribble adhesive waterproof tape 27, to increase near the surface mobility regional 26, making has the flow mistake herein.The length of adhesive waterproof tape 27 can be 15% to 25% of limit 22 length.
Above-mentioned embodiment does not consist of limiting the scope of the invention.Those skilled in the art should be understood that, depend on design requirements and other factors, and various modifications, combination, sub-portfolio and alternative can occur.Any modification of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within the protection domain of the present invention.
