The two ends of the length direction of reverse osmosis membrane group 120 and the central tube group 110, and respectively with the multiple reverse osmosis membrane group
120 are tightly connected；First end cap 130 is provided with the waste water discharge opening 131 being connected with the DI 111 and (refers to figure
4)；Second end cap 140 is provided with the pure water outlet 141 (referring to Fig. 4) being connected with the waste pipe 112；It is described outer
Shell 200 includes bottle 210 and is covered on the lid 220 of the bottle 210, and the membrane component 100 is installed on the shell 200
In, the lid 220 is docked with first end cap 130, and the lid 220 is provided with the waste water chamber connected with outside water route, institute
Waste water chamber is stated to connect with the waste water discharge opening 131 sealing；The bottle 210 is docked with second end cap 140, the bottle
210 connect provided with the pure water chamber and raw water chamber connected respectively with outside water route, the pure water chamber and the pure water outlet 141 sealing
Logical, the raw water chamber and the membrane component 100 are connected with the space between the bottle 210.
The waste water discharge opening 131 of membrane component 100 is arranged on the first end cap 130 in technical solutions of the utility model, pure water
Outlet 141 is arranged on the second end cap 140 so that pure water and waste water can be discharged from different directions, in this way, in the lid
Body 220 only needs to set the waste water chamber connected with outside water route, without setting pure water chamber and raw water chamber, simplifies lid 220
Structure, meanwhile, the bottle 210 sets the pure water chamber and raw water chamber connected respectively with outside water route, is changed without water route
Device is the separation that water route can be achieved, and facilitates alignment and sealing at lid 220 to install, simplifies whole counter-infiltration filter core 900
Assembling；Connected by waste water chamber with the sealing of waste water discharge opening 131, the space between raw water chamber and membrane component 100 and bottle 210 connects
Logical, pure water chamber is connected with the sealing of pure water outlet 141, is realized filter core lid 220 and is gone out waste water, bottle 210 enters raw water, goes out pure water
Waterway structure, can preferably distinguish pure water and waste water, smaller pure water is by the risk of contaminated wastewater.
Wherein, the central tube group 110 of reverse-osmosis membrane element 100 includes the useless of DI 111 and multiple circular DIs 111
Water pipe 112；The corresponding one page reverse osmosis membrane group 120 of each waste pipe 112 of reverse-osmosis membrane element 100 is more so as to realize
Film page is batched, and can increase runner quantity, is conducive to improving raw water flux, and solve the long osmotic pressure of reverse osmosis membrane 121 not
The problem of foot causes part reverse osmosis membrane 121 and not up to filters purpose；Because the central tube group 110 is by multipage reverse osmosis membrane
Piece group 120 seals 120 liang of those reverse osmosis membrane groups wound on center, therefore in the first end cap 130 and the second end cap 140
Behind end, the water inlet of the outer side edges effluent of multipage reverse osmosis membrane group 120 can be formed, middle waste pipe 112 discharges the raw water water of waste water
Road；Counter-infiltration filter core 900 is in use, raw water is intake by effluent, and runner narrows, and water inlet area reduces, and flow also increases greatly
It is long, therefore the time that raw water is contacted with reverse osmosis membrane 121 can be increased, improve the raw water rate of recovery；Meanwhile, because reducing original
Water intake area, can increase the surface water velocity of reverse osmosis membrane 122 (enter water flux it is certain when, enter water flux Q and current
Relation between speed V is V=Q/S；Wherein, S is water inlet area, specifically, S=Ld；L is water inlet end diaphragm length, and d is to cut
Face thickness, effluent, which is mainly, reduces L, in addition can be with reduce thickness d) with the small water inlet flow-guiding screen 122 of thickness, it is thus possible to subtract
The small surface concentration polarization of reverse osmosis membrane 121, reduces the pollution speed of the reverse-osmosis membrane element 100, is conducive to improving raw water time
Yield, so as to improve the waste problem of raw water.
Referring to Fig. 3, collecting pure water for convenience, the DI 111 can be set away from the pure water outlet 141
One end blocked, to cause pure water to be flowed towards the pure water outlet 141；Now, pure water flow direction is certain, Neng Gouke
The collection pure water leaned on.Waste water is exported for convenience, can design at least one described waste pipe 112 away from the waste water discharge opening
131 one end is blocked, to cause waste water to be flowed towards the waste water discharge opening 131, after closure, and waste water flow direction is certain,
Waste water can reliably be collected.In actual use, what reverse-osmosis membrane element 100 was usually placed vertically, it is corresponding described pure
Water pipe 111 and multiple waste pipes 112 are also vertically put, now, are collected waste water from upper end and are collected useless from lower end
Water, uniform fluid flow, and be conducive to waterway seal, so as to avoid the mixing or pollution of pure water and waste water, it is easy to reverse osmosis water system
Design.Specific mobility status, can refer to 3, wherein the instruction of the dotted line with arrow is water (flow) direction, pure water enters water from pure water
Hole 113 (referring to Fig. 4) enters DI 111, and DI 111 is flowed downward out along the tunnel of DI 111；Waste water enters water from waste water
Hole 114 (referring to Fig. 5) enters waste pipe 112, and waste pipe 112 is flowed upwards out along the tunnel of waste pipe 112.Refer to Fig. 2 and figure
4, in order to realize the separation of raw water and waste water, a circle sealing rib 134, sealing can be set on the outer wall of the first end cap 130
Rib 134 reclines with bottle 210, can stop that raw water is flow in lid 220, so as to avoid raw water dirty by the waste water at lid
Dye.
The particular number of waste pipe 112 determines the quantity of reverse osmosis membrane group 120, also determines the chi of DI 111
It is very little, specifically, one waste pipe 112 of correspondence of reverse osmosis membrane group 120 is set, the more at most reverse osmosis membrane of waste pipe 112
The quantity of group 120 is more, and the flux of corresponding reverse-osmosis membrane element 100 is also bigger, and the size of DI 111 is also accordingly got over
Greatly.The shape of the particular number of waste pipe 112, shape and correspondence DI 111 can be set according to actual conditions, be referred to
Fig. 5 simultaneously combines Fig. 4 understandings, and in an embodiment of the present utility model, the quantity of the waste pipe 112 is N number of, and N is more than or waited
