Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
The present invention is based on that the discovery of present inventor to the following fact and problem make: the composite filter element of such as counter-infiltration filter core in correlation technique, function singleness, cannot meet the requirement of properties when filtering water simultaneously.But, present inventor is found by large quantifier elimination and experiment, filter membrane in counter-infiltration filter core, in filter core, be wound in multilayer filter for water, because the flux of filter membrane itself and salt rejection rate can not get both, the flux of the filter core of the corresponding filter membrane of employing and salt rejection rate can not be got both, that is, adopt the counter-infiltration filter core of the filter membrane of large flux, its salt rejection rate is low; Adopt the counter-infiltration filter core of the filter membrane of equipment with high desalinization, its flux is little.
Below with reference to the accompanying drawings filtering film component 1 according to the embodiment of the present invention is described.
As shown in Fig. 1-Fig. 7, comprise central tube 100, multiple pure water selvage guide 200 and at least two kinds of filtration membranes 300 according to the filtering film component 1 of the embodiment of the present invention.
The sidewall of central tube 100 was provided with the mouth of a river 110 and end is provided with intake-outlet 120.Multiple pure water selvage guide 200 is wound on the periphery of central tube 100 and centrally the radial direction of pipe 100 is stacked.Often kind of filtration membrane 300 is at least one, multiple filtration membrane 300 be wound on the periphery of central tube 100 and each filtration membrane 300 in the radial direction of central tube 100 between adjacent pure water selvage guide 200.Here it will be appreciated that, the number of pure water selvage guide 200 is according to the kind of filtration membrane 300 and number adjustment, to ensure that each filtration membrane 300 all can between adjacent pure water selvage guide 200, serve as the mouth of a river 110 when intaking, intake-outlet 120 water outlet, when intake-outlet 120 is intake, cross the mouth of a river 110 water outlet.
According to the filtering film component 1 of the embodiment of the present invention, by arranging at least two kinds of filtration membranes 300, at least two kinds of filtration membranes 300 pairs of water can be utilized to filter.At least two kinds of filtration membrane 300 pairs of water with difference in functionality can be selected like this to filter, such as, can select a kind of to there is the filtration membrane 300 of large flux and a kind of filtration membrane 300 with equipment with high desalinization, not only can ensure the water demineralizing rate of convection current membrane module 1 after filtration, and the flux of water at filtering film component 1 can be improved.Not only can realize corresponding function by selecting different types of filtration membrane 300 thus, and can by the purifying water effect of the quantity regulating filtering film component 1 between the different types of filtration membrane 300 of adjustment, such as by adjusting salt rejection rate and the flux magnitude of the quantity adjustment filtering film component 1 of the filtration membrane 300 of large flux and the filtration membrane 300 of equipment with high desalinization, thus improve the diversity of the function of filtering film component 1, improve the applicability of filtering film component 1.
And, by arranging multiple pure water selvage guide 200, each filtration membrane 300 can be made in the radial direction of central tube 100 between adjacent pure water selvage guide 200, pure water selvage guide 200 pairs of filtration membranes 300 can be utilized like this to position, not only so that be wound on central tube 100 by filtration membrane 300, and can improve the stability after filtration membrane 300 winding.
In addition, because multiple pure water selvage guide 200 is wound on the periphery of central tube 100 and centrally the radial direction of pipe 100 is stacked, each filtration membrane 300 in the radial direction of central tube 100 between adjacent pure water selvage guide 200.Pure water selvage guide 200 pairs of water can be utilized like this to lead, after all filtration membranes 300 filters, utilize multiple pure water selvage guide 200 that water is pooled to central tube 100 place at water, the water after filtration passed through to be discharged by intake-outlet 120 after the mouth of a river 110 enters central tube 100 to take for user.Not only can ensure that current can through each filtration membrane 300 thus, to ensure water purification effect, and can so that lead to the water after filtering and collect, so that water is by filtering film component 1.
