Detailed description of the invention
Below in conjunction with the elaboration that Fig. 2 ~ Fig. 4 carries out specifically to the technical scheme that the utility model provides, the arbitrary technological means provided by the utility model carries out technical scheme that two or more technological means any of replacing or being provided by the utility model or technical characteristic carry out mutually combining and obtain all should within protection domain of the present utility model.
The utility model embodiment provides a kind of water inlet flow-guiding screen, comprising: longitudinal rib 10 and the dowel 20 being connected longitudinal rib 10.The sectional dimension of longitudinal rib 10 is greater than the sectional dimension of dowel 20, and dowel 20 is between the plane of the opposite flank of longitudinal rib 10 and keep and the plane spaced-apart of side, to make the only having side of longitudinal rib 10 to contact with diffusion barrier in water purification diaphragm group.
See Fig. 4, namely the plane B at the place, two sides of dowel 20 is between the plane A at the place, two sides of longitudinal rib 10, to make the only having plane A at the place, side of longitudinal rib 10 can contact with diffusion barrier in water purification diaphragm group.
Longitudinal rib 10 can adopt existing linear structure, and dowel 20 has multiple implementation, hereinafter will provide its preferred implementation.Diffusion barrier also can be described as counter-infiltration diaphragm.
The cross sectional shape of longitudinal rib 10 and dowel 20 has multiple, can be circular, oval, regular polygon shape (such as regular pentagon, regular hexagon etc.), hereinafter will provide preferred implementation.
Technique scheme, sectional dimension due to longitudinal rib 10 is greater than the sectional dimension of dowel 20, therefore in actual motion, only have longitudinal rib 10 to contact with the face of diffusion barrier in water purification diaphragm group, when the mesh-density of the water inlet flow-guiding screen that technique scheme provides and the mesh-density of existing water inlet flow-guiding screen are more or less the same, its contact area is less than the gross area that in prior art, longitudinal rib contacts with face with horizontal bar.The place that face does not contact with longitudinal rib 10 muscle all can contact with feed liquid, for material mass transfer, so just makes effective usable floor area of diffusion barrier in water purification diaphragm group increase, improves face mass-transfer efficiency.
Dowel 20 specifically can adopt following structure: dowel 20 is the enclosed construction of rounding off.
Adopt said structure; not easily produce at four Angle Position of the grid of water inlet flow-guiding screen the dead angle being easy to accumulation of pollutants, make the runner of coiled reverse osmosis membrane element unimpeded, thus the pressure reduction of membrane component is reduced; aquifer yield increases, and energy available protecting counter-infiltration diaphragm is from damage.
Further, dowel 20 is circular muscle or oval dowel.To use circular muscle in the present embodiment, circular muscle can effectively reduce, even stop the pollutant that produces into the grid surrounding of water flow-guiding screen is detained and deposition dead angle, thus extends the service life of counter-infiltration diaphragm.In addition, the existence of dowel 20, makes in feed water flow to time constant, water inlet is subject to the disturbance of dowel 20 in runner, forms the continuous change thus formation disturbance that flow to, facilitates the conversion to turbulent flow into water from laminar flow, effectively reduce the concentration polarization phenomenon on film surface, facilitate material mass transfer.
In the present embodiment, the cross section of longitudinal rib 10 and the cross section of dowel 20 specifically can adopt following shape: the cross sectional shape of longitudinal rib 10 is for circular or oval.And/or the cross sectional shape of dowel 20 is circular or oval.
Such as, the cross sectional shape of longitudinal rib 10 is circular, and the cross sectional shape of dowel 20 is oval.Or the cross sectional shape of longitudinal rib 10 is oval, the cross sectional shape of dowel 20 is circular.Or the cross sectional shape of longitudinal rib 10 is identical with the cross sectional shape of dowel 20, be all circular or oval.
Adopt longitudinal rib 10 and the dowel 20 of said structure, can not face be damaged in the process contacted with face, ensure that strainability.
See Fig. 2, dowel 20 is specifically connected with the middle part of longitudinal rib 10.For the cross sectional shape of longitudinal rib 10 for circle, herein, the middle part of longitudinal rib 10 specifically refers to around the center of circle of longitudinal rib 10.Make in actual motion, only have longitudinal rib 10 directly to contact with counter-infiltration diaphragm face like this, dowel 20 does not contact with face, so the contact area of water inlet liquid material and face increases, thus effective usable floor area of diffusion barrier in rolled membrane module is increased, namely effective filtration area increases, and improves face mass-transfer efficiency.
Mention that the sectional dimension of longitudinal rib 10 is greater than the sectional dimension of dowel 20 above, adopt circular configuration for both simultaneously, longitudinal rib 10 is 2:1 ~ 10:1 with the ratio of the external diameter of dowel 20.Be specifically as follows 2:1,3:1,4:1,6:1,8:1,10:1 etc.
Adopt above-mentioned ratio, the contact area of the face into water flow-guiding screen and counter-infiltration diaphragm can be effectively reduced, so just make effective usable floor area of diffusion barrier in water purification diaphragm group increase, thus increase face mass-transfer efficiency.
The utility model embodiment provides again a kind of water purification diaphragm group, comprises the water inlet flow-guiding screen that the arbitrary technical scheme of the utility model provides.
The utility model embodiment also provides a kind of coiled reverse osmosis membrane element, comprises the water purification diaphragm group that the arbitrary technical scheme of the utility model provides.
Reverse-osmosis membrane element comprises water purification diaphragm Zu He center water producing pipe, and the sealing of water purification diaphragm group is wrapped on the water producing pipe of center.Water purification diaphragm group specifically comprises into water flow-guiding screen, counter-infiltration diaphragm and pure water flow-guiding screen.
The utility model embodiment reoffers a kind of purifier, and it comprises the coiled reverse osmosis membrane element that the arbitrary technical scheme of the utility model provides.
