The specific embodiment

To shown in Figure 2, be an embodiment of the present utility model as Fig. 1, it filters composite filter element structure (the arrow line indication is a water (flow) direction among the figure) for a kind of monomer dual channel, adopts principle of reverse osmosis to filter former water.In the utility model, the basic functional principle of counter-infiltration is: make current penetrate the aperture under the effect of pressure and have only 0.0001 micron reverse osmosis membrane.Because only 0.0001 micron in the aperture of reverse osmosis membrane, bacterium will dwindle 4,000 times, filterable virus and also will dwindle more than 200 times and could pass through.Therefore all fine impure impurity in the water, harmful soluble solids and bacterium, virus, heavy metal, inorganic salts etc. can't penetrate high-precision reverse osmosis membrane.This monomer dual channel filters the composite filter element structure and comprises a cylindrical shell 1, an interior composite filter element 2 and the water inlet 3 on the cylindrical shell 1 and two delivery ports 4 of cylindrical shell.This delivery port 4 comprises a water purification passage A and a pure water channel B, is provided with an interface 41 in the pure water channel B, and wherein water purification passage A links to each other with domestic water equipment, and is first-class as water closet, shower and the fire hose, and the pure water channel B links to each other with drinking equipment.Composite filter element 2 is by being made up of foldable filter element layer 21, polypropylene melt blown filter layer 22, active carbon filtration layer 23 and film pipe 24 to interior outer.The medium that each filtering layer and film pipe filter in this composite filter element 2 is respectively: ground floor is a foldable filter element layer 21, the medium of its filtration is the above foreign matter of pore size filter (for example 40 μ m) that sets, as visual filths in one's power of eyes such as iron rust, silt, small worm, leaves.The second layer is a polypropylene melt blown filter layer 22, and the medium of its filtration is any foreign matter and the filth of the above size of pore size filter (for example 5 μ m) that sets, and the pore size filter of the second layer is littler than the pore size filter of ground floor.The 3rd layer is active carbon filtration layer 23, and the medium of its filtration is pollutants such as organic pollution in the water, bleaching powder or other part heavy metals.The 4th layer is film pipe 24, interior dress reverse osmosis membrane, wherein the reverse osmosis membrane aperture is 0.0001 μ m, any interior three-stage filtration water of film pipe that enters, pure water can infiltrate through internal layer by the skin by this reverse osmosis membrane, and flow to delivery port 4, flow to drinking equipment from the pure water channel B, because the capacity limit of moisture storage capacity, after having the part pure water to use, three-stage filtration water just can be proceeded the filtration of reverse osmosis membrane, all the other inorganic salts and bacterium, virion, heavy metal can not pass through, all directly flow to water purification passage A, provide each domestic water equipment to use from the reverse osmosis membrane skin with the water that does not pass through reverse osmosis membrane filtration.The corresponding interface of pure water channel B 41 is directly inserted in the water side of this film pipe 4, but close with the O type rubber ring water conservation of film pipe water side, separates the water supply of the different clean degree of water purification passage and pure water passage.Be connected with film pipe watertight water stop rubber circle 5 between active carbon filtration layer 23 and the film pipe 24, can contact with core inside pipe wall among the bottom and fix, be used to limit water (flow) direction through active carbon filtration layer 23.Composite filter element 2 bottoms and cylinder are connected with fixing outstanding watertight dividing plate 6, are used to limit the current direction composite filter element 2 of water inlet 3, and make the current direction delivery port 4 that filters through composite filter element.Cylindrical shell 1 bottom has the delivery port switch 11 of an effluent, as the higher area of water hardness, just can connect flow-limiting valve and the suitably discharging of water pipe do, also can regularly discharge.

As shown in Figure 3, be another embodiment of the present utility model, its difference is dress hollow fiber membrane in the film pipe 24.The hollow fiber membrane side all has the hole up and down, can flow into this film pipe 24 from the hole, top through the water behind the three-stage filtration, and filtrable water can flow to drinking equipment from the pure water channel B.That can not filter flow to water purification passage A by the hole, bottom, provides each domestic water equipment to use.Composite filter element 2 is fixed by a bottom 7 on one and a lower bottom cover 8.

When filter is worked, former water enters cylindrical shell 1 by water inlet 3, after handling through the three layers of primary filter in front, organic compounds such as rugosity impurity in the water, peculiar smell, heterochromatic, chlorine are removed, enter film pipe 24 again and do the counter-infiltration purified treatment, thereby effectively remove fine impurity such as organic matter in the water, bacterium, virus.The water that filters out through film pipe 24 can reach the standard of drinking raw, flow to drinking equipment by the pure water channel B, also the water that filters without film pipe 24 filters owing to passing through the three first layers filter course, can flow to each domestic water equipment by water purification passage A when needed, and impurity is discharged.(running water is because of adding the chlorination of appropriateness, and in fact bacterium and virus do not exist)

Do not contain motor in the utility model, do not need power supply, filter by hydraulic drives.Each layer material is compound, can for example polypropylene melt blown filter layer 22 be placed the 3rd layer according to design variation, and active carbon filtration layer 23 is placed the second layer.Twin-channel effect that the utility model adopted, be that former water is through behind the multistep treatment, when filmed passing tube 24, the permeable pure water that is, can drink via pure water channel B to drinking equipment, thoroughly filmed passing tube 24 and flow out another water purification passage A be domestic water can for the washing and other uses in life, this type of uses in the soft place of water hardness, need not draining.But as if the higher or higher water quality of the hardness district at inorganic salt, need adorn a flow-limiting valve waste discharge, however, the water ratio of being discharged is still saved and can be reached more than 75% than existing system.
