Detailed description of the invention
Refer to Fig. 1 and Fig. 2, what Fig. 1 and Fig. 2 disclosed is a kind of structure improving RO counter-infiltration diaphragm utilization rate and flux, comprise central tube 1, also comprise some layers of RO reverse osmosis membrane 2, one end of some layers described RO reverse osmosis membrane 2 is connected with the sidewall of described central tube 1, the other end of some layers described RO reverse osmosis membrane 2 rolls together centered by described central tube 1, thus forms filter core.Some layers described RO reverse osmosis membrane 2 rolls to same direction, is provided with some water inlet structures 11 between two-layer described RO reverse osmosis membrane 2 adjacent on described central tube 1.
In the present embodiment, described RO reverse osmosis membrane 2 comprises the filter cloth 21, primary diaphragm 22, filter screen 23 and the secondary diaphragm 24 that are superimposed together successively, described primary diaphragm 22 and described secondary diaphragm 24 shift to install the both sides at described filter screen 23, and namely the length of described primary diaphragm 22 is less than the length of described secondary diaphragm 24.When rolling, described primary diaphragm 22 is in inner side, described secondary diaphragm 24 is in outside, like this after having rolled, one end away from described central tube 1 of described primary diaphragm 22 and the alignment of the one end away from described central tube 1 of described secondary diaphragm 24, namely the length of described primary diaphragm 22 one end is equal with the length of described secondary diaphragm 24 one end.The benefit of such design economizes on resources, and improves the utilization rate of described RO reverse osmosis membrane 2.
In the present embodiment, one end of described filter cloth 21 is welded on the sidewall of described central tube 1, and described water inlet structure 11 is that inlet opening is or/and intake chamber.One end of some layers described RO reverse osmosis membrane 2 is distributed on the sidewall of described central tube 1 symmetrically.
In the present embodiment, the fixing male end also comprising fixing female end and coordinate with described fixing female end, described fixing male end is fixedly connected with one end of described RO reverse osmosis membrane 2, and described fixing female end is arranged on the sidewall of described central tube 1.The benefit of such design is, be easy for installation and removal described RO reverse osmosis membrane 2, when described RO reverse osmosis membrane 2 damages, can change damage with new described RO reverse osmosis membrane 2, has saved resource and has reduced living cost.Described fixing female end is hole clipping or chute, and described fixing male end is protruding buckle or slide block.And user according to the demand of oneself, can increase or reduce the number of plies of described RO reverse osmosis membrane 2.
The utility model, the salt rejection rate that improve and the flow adding water, in same film area situation, a described RO reverse osmosis membrane structural rate skim of the prior art structure in the utility model adds water flow (in identical diaphragm area situation, RO reverse osmosis membrane 2 described in many increases one deck, just increases by the water flow of 18%).And in the process of filtering, define cross-flow filtration, water needs through described filter screen 23, described primary diaphragm 22, described secondary diaphragm 24 and described filter cloth 21, then flows to described central tube 1 from described water inlet structure 11, finally water outlet from described central tube 1.When through described filter screen 23 and described filter cloth 21, water is not that straight line is walked, it needs the shape along described filter screen 23 and described filter cloth 21 to turn back to pass through, benefit is that water increases through the route of described primary diaphragm 22 and described secondary diaphragm 24, namely contact area is equivalent to many, water so through the filtration of described primary diaphragm 22 and described secondary diaphragm 24 is also just many, improves the strainability of described RO reverse osmosis membrane structure.
Described RO reverse osmosis membrane structure also has the effect extending resistance, when the described RO reverse osmosis membrane 2 of some layers rolls together, described in top view during described RO reverse osmosis membrane structure, can find that described filter screen 23 and described filter cloth 21 are clipped between described primary diaphragm 22 and described secondary diaphragm 24 respectively, form hollow, for choked flow, namely the water inlet end of described RO reverse osmosis membrane structure makes water stop on primary diaphragm 22 and described secondary diaphragm 24 to filter, simultaneously because choked flow effect makes hydraulic pressure increase, salt rejection rate also can promote accordingly (pressure influence strainability, the larger filter effect of pressure is quite a lot of), water side choked flow forms water and filters further in described primary diaphragm 22 and described secondary diaphragm 24, there is adsorption function on the surface of described primary diaphragm 22 and described secondary diaphragm 24, can to the further impurity absorption of water.
