Abstract
The utility model discloses a roll type reverse osmosis membrane element, which comprises a central produced water tube and a reverse osmosis membrane wound on the central produced water tube, wherein the reverse osmosis membrane is folded, so that an influent water flow passage and a produced water flow passage are formed, partial sections of both fold-neighboring sides of the influent water flow passage, which are far from the central produced water tube, are hermitically closed, so that small sections of raw water inlets are respectively formed on the two sides close to the central produced water tube and a concentrated water outlet is formed on the side of the influent water flow passage opposite to a fold, water inlet tubes are arranged in the raw water inlets, and each water inlet tube is provided with a plurality of small holes facing the concentrated water outlet. The roll type reverse osmosis membrane element has the advantages that the water inlet dead angle of the raw water inlet is eliminated, scaling at the raw water inlets is prevented, and thereby water quality is increased.
Description
Technical field
The utility model belongs to the clean water treatment technical field, relates to the reverse-osmosis membrane element of removing impurity such as silt, mud, colloid, microorganism, virus, organism and inorganic salt in the water, relates in particular to a kind of coiled reverse osmosis membrane element.
Background technology
At present, known coiled reverse osmosis membrane element is with by pure water water conservancy diversion net, the reverse osmosis diaphragm, the water purification diaphragm group that the stack of water inlet water conservancy diversion net constitutes is wrapped on the water producing pipe of center and forms, wherein the reverse osmosis diaphragm is folded, in the inlet conduit that constitutes between the internal surface of described water inlet water conservancy diversion net after the reverse osmosis diaphragm is folding, in the product water flow passage that constitutes between the outside surface of described pure water water conservancy diversion net after the reverse osmosis diaphragm is folding, this coiled reverse osmosis membrane element is to produce the end face dual-side of water flow passage and to have towards the opening of center water producing pipe with the bonding product water flow passage that makes of glue away from a side of center water producing pipe, water purification diaphragm group is behind the water producing pipe of the center of winding, and entire exterior surface is carried out environmental sealing with outer adhesive tape.The rolling ro components of this structure, it is from the inflow inlet conduit of an end face of element, part water filters the formation pure water through the reverse osmosis diaphragm and flows in the water producing pipe of center along pure water water conservancy diversion net, and the remaining dense water that forms that filters flows out from the other end of element along the water inlet water conservancy diversion net in the inlet conduit.The direction that the water inlet direction and the concentrated water drainage of this reverse-osmosis membrane element go out is consistent, but because runner is wide, flow process is short, the speed of water inlet in runner is slower, and the film surface is easy to generate the concentration polarization phenomenon, thereby causes membrane element to pollute, make ratio of desalinization and water production rate reduce the membrane element lost of life.
Afterwards, the applicant was in order to overcome above-mentioned defective, utility model a kind of coiled reverse osmosis membrane element, to China Intellectual Property Office's deduction patent application, application number is 200910201739.8.This coiled reverse osmosis membrane original paper is the dual-side adjacent with flanging of the inlet conduit part section closing seam away from the center water producing pipe, make this dual-side form the segment raw water inlet respectively near center water producing pipe place and make inlet conduit form dense water water outlet with the flanging opposed side edges.The reverse-osmosis membrane element of this spline structure is that the raw water inlet from the inlet conduit of the end face both sides of element enters the inlet conduit, part water obtains pure water through reverse osmosis membrane filtration and enters to produce and enter the center water producing pipe along pure water water conservancy diversion net in the water flow passage and form pure water, the dense water that another part filtered forms dense water water outlet relative with flanging along water inlet water conservancy diversion net from inlet conduit in inlet conduit discharged, even also discharge from the edgewise circumferential surface of membrane element from winding direction along water purification diaphragm group, and unlike the reverse-osmosis membrane element of prior art, former water flows to from an end face of coiled reverse osmosis membrane element, and dense water flows out from the other end of membrane element.Through such improvement, strengthened the flow velocity on reverse-osmosis membrane element film surface, reduced film surface concentration polarization, reduce the pollution speed of rolled film element, thereby prolonged the work-ing life of membrane element.But this coiled reverse osmosis membrane finds that in use owing to be 90 degree water inlets, there is into water dead angle at the raw water inlet place, and the time has been grown easy fouling, influences effluent quality.
The utility model content
Technical problem to be solved in the utility model provides a kind of coiled reverse osmosis membrane element, and this coiled reverse osmosis membrane original paper can be eliminated the water inlet dead angle of raw water inlet, avoids the raw water inlet fouling and influences water quality.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of coiled reverse osmosis membrane element, by the center water producing pipe, the reverse osmosis diaphragm that is wrapped on the water producing pipe of center constitutes, wherein the reverse osmosis diaphragm is through being folded to form inlet conduit and producing water flow passage, the dual-side adjacent of described inlet conduit with flanging make this dual-side form the segment raw water inlet respectively away from the part section closing seam of center water producing pipe near center water producing pipe place and make inlet conduit form dense water water outlet with the flanging opposed side edges, it is characterized in that: be provided with water inlet pipe in the described raw water inlet, have a plurality of apertures on the described water inlet pipe towards dense water water outlet.
Adopt technique scheme, by be provided with water inlet pipe in raw water inlet, water inlet flows to water inlet pipe earlier, and the aperture from water inlet pipe sprays into inlet conduit to dense water water outlet direction then, makes water inlet evenly, can not have the water inlet dead angle, thereby avoid fouling.
Flush at the mouth of pipe of water inlet pipe described in the preferred implementation of the present utility model and the side adjacent of described inlet conduit with flanging.This spline structure makes that water inlet is more smooth and easy.
In embodiment of the present utility model, described reverse osmosis diaphragm is through being folded to form two-layer inlet conduit and producing water flow passage, and described every layer of inlet conduit two ends all have raw water inlet,
Be equipped with water inlet pipe in described each raw water inlet.
Description of drawings
Below in conjunction with accompanying drawing and the utility model embodiment the utility model is elaborated:
Fig. 1 is a structural representation of the present utility model.
Among the figure:
