Chamber, the sidewall of central canal arranges water hole, and this water hole connects with water cavity；Film bag is wound on central canal, film bag and film bag
Between water inlet grid is set, the internal water hole by central canal of film bag connects with water cavity；Film bag and water inlet grid upper end are former
Water water inlet end, it is concentrated water discharge end that former water enters the water cavity of central canal, film bag and water inlet grid lower end after film bag filtration；Water inlet
The former water water inlet end of grid and the thickness of concentrated water discharge end, more than the mid portion thickness of water inlet grid, are intake in the thickness of grid two ends
Between thin type Cheng Kuanyuan water water inlet flow channel, narrow middle water inlet flow channel and wide concentrated water drainage water flow passage.
Further, the width of the former water water inlet end of grid of intaking and each grid of concentrated water discharge end is more than water inlet grid
The width of each grid of mid portion.
Further, film bag by upper strata reverse osmosis membrane, lower floor's reverse osmosis membrane and is placed in upper strata reverse osmosis membrane and lower floor's reverse osmosis
Flow-guiding cloth composition between permeable membrane, this flow-guiding cloth is connected with water cavity by the water hole of central canal, and former water is through upper strata reverse osmosis membrane
With enter flow-guiding cloth after lower floor reverse osmosis membrane filtration, flow-guiding cloth be drained in the water cavity of central canal.
Using after such scheme, the present invention intakes the former water water inlet end of grid and the thickness of concentrated water discharge end more than water inlet lattice
The mid portion thickness of net, it is dense that water inlet grid two ends thickness intermediate thin forms wide former water water inlet flow channel, narrow middle water inlet flow channel and width
Water draining runner.Therefore, being effectively increased into water flux, middle water inlet flow channel narrows and can reach pressurized effect, improves the unit interval
Interior pure water aquifer yield, and dense water water side is wide flow passage structure, effectively reduces concentration polarization effect, makes dirt be difficult in reverse osmosis
Film surface attachment.The reverse-osmosis membrane element of structure of the present invention, can also extend reverse osmosis membrane while increasing pure water flow
Service life, for family's water purification industry, there is bigger application prospect and commercial value.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in detail.
Refer to described in Fig. 1 to Fig. 8, a kind of big flow long-life coiled reverse osmosis membrane element that the present invention discloses, including
Central canal 1, film bag 2 and water inlet grid 3.
Central canal 1 is formed water cavity, the sidewall of central canal 1 arranges water hole 11, as it is shown on figure 3, generally arrange a row
Water hole 11, this water hole 11 connects with water cavity, water cavity not shown in figure.
Film bag 2 is wound on central canal 1, arranges water inlet grid 3 between film bag 2 and film bag 2, and film bag 2 is internal passes through center
The water hole 11 of pipe 1 connects with water cavity.As shown in Figure 6, can be entered by package adhesive tape 4 after film bag 2 is wound on central canal 1
Row encapsulation.
Generally, film bag 2 by upper strata reverse osmosis membrane, lower floor's reverse osmosis membrane and is placed in upper strata reverse osmosis membrane and lower floor's reverse osmosis
Flow-guiding cloth composition between film, this flow-guiding cloth is connected with water cavity by the water hole 11 of central canal 1, and former water is through upper strata reverse osmosis membrane
With enter flow-guiding cloth after lower floor reverse osmosis membrane filtration, flow-guiding cloth be drained in the water cavity of central canal 1.
Film bag 2 and water inlet grid 3 upper end are former water water inlet end, and former water enters the water cavity of central canal 1 after film bag 2 filters,
Film bag 2 and water inlet grid 3 lower end are concentrated water discharge end.
As it is shown in figure 5, the thickness of the former water water inlet end 31 of water inlet grid 3 and concentrated water discharge end 32 is more than water inlet grid 3
Mid portion 33 thickness, water inlet grid 3 two ends thickness intermediate thin forms wide former water water inlet flow channel, narrow middle water inlet flow channel and the dense water of width
Draining runner.
The present invention intakes the thickness of the former water water inlet end 31 of grid 3 and concentrated water discharge end 32 more than the pars intermedia of water inlet grid
33 thickness, water inlet grid 3 two ends thickness intermediate thin are divided to form wide former water water inlet flow channel, narrow middle water inlet flow channel and wide concentrated water drainage current
Road.Therefore, being effectively increased into water flux, middle water inlet flow channel narrows and can reach pressurized effect, and in improving the unit interval, pure water produces
The water yield, as it is shown in fig. 7, and dense water water side be wide flow passage structure, effectively reduce concentration polarization effect, as shown in Figure 8, make dirt
Dirt is difficult in reverse osmosis membrane surface attachment.The reverse-osmosis membrane element of structure of the present invention, also may be used while increasing pure water flow
To extend the service life of reverse osmosis membrane.
As it is shown in figure 5, the width of each grid of the water inlet former water water inlet end 31 of grid 3 and concentrated water discharge end 32 be more than into
The width of each grid of mid portion 33 of water grid 3 so that the former water water inlet end 31 current seepage velocity of water inlet grid 3 is relatively
Hurry up, mid portion 33 seepage velocity of water inlet grid 3 is relatively slow, and the concentrated water discharge end 32 current seepage velocity of grid 3 of intaking is relatively
Hurry up, so that current rapidly enter reverse osmosis membrane carries out filtration treatment, increase the aquifer yield of unit interval, meanwhile, dense water by
The concentrated water discharge end 32 of water inlet grid 3 is quickly discharged, and dense water water outlet is fast, it is not easy to bonding.
The foregoing is only the preferred embodiments of the present invention, not the restriction to this case design, all designs according to this case are closed
The equivalent variations that key is done, each falls within the protection domain of this case.
