Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing 1 is a flowage structure synoptic diagram of the present utility model.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model is described in further detail, but present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof all should be listed protection domain of the present utility model in.
Fig. 1 comprises: preprocessing filter element 2, high-pressure hydraulic pump 3, reverse osmosis membrane group 6, flow-limiting valve group 20, it is characterized in that: the reverse osmosis membrane group is set to three films, wherein in parallel use of reverse osmosis membrane A7 and reverse osmosis membrane B11 is the first step, reverse osmosis membrane C15 is the second stage, be connected with the water-in 16 of reverse osmosis membrane C15 after dense water out 14 UNICOMs of the dense water out 10 of reverse osmosis membrane A7 and reverse osmosis membrane B 11, the concentrated water spout 18 of reverse osmosis membrane C15 connects flow-limiting valve group 20 water-ins 21; Flow-limiting valve group 20 has a water-in 21 and water outlet A 23 and water outlet B 22, be connected with the needle-valve 24 of adjustable throttle amount and the set current limiting valve 25 that is connected in parallel with it between water-in 21 and the water outlet A 23, be connected with the needle-valve 26 of adjustable throttle amount between water-in 21 and the water outlet B 22.Water outlet A 23 is used for the directly outwards discharging of dense water, and water outlet B 22 is communicated with the water-in 4 of high-pressure hydraulic pump 3.
Can see from Fig. 1 signal, former water flows into the back from water inlet interface 1 and carries out pre-treatment through preprocessing filter element 2 earlier, water-in 4 through high-pressure hydraulic pump 3 enters high-pressure hydraulic pump 3 superchargings, pretreated water after the supercharging of high-pressure hydraulic pump 3 water outlets 5 outputs enters the water-in 8 of reverse osmosis membrane A7 and the water-in 12 of reverse osmosis membrane B11 simultaneously, dense water after the processing is discharged from the dense water out 10 of reverse osmosis membrane A7 and the dense water out 14 of reverse osmosis membrane B11, sends into the water inlet of the water-in 16 of reverse osmosis membrane C15 as reverse osmosis membrane C15 simultaneously.
The pure water that obtains after handling through reverse osmosis membrane A7, reverse osmosis membrane B11, reverse osmosis membrane C15 merges the back from 19 outputs of pure water interface.
The concentrated water spout 18 of reverse osmosis membrane C15 connects flow-limiting valve group 20 water-ins 21.Dense water is divided into two-way after entering flow-limiting valve group 20, after the needle-valve 24 of one tunnel process adjustable throttle amount and set current limiting valve 25 current limlitings that are connected in parallel with it the dense water of part is directly discharged from water outlet 23 as the dense water of whole water treatment system.Another road send into the water-in 4 of high-pressure hydraulic pump 3 through the needle-valve 26 of adjustable throttle amount and after the pretreated water mixing that preprocessing filter element 2 was handled as the water inlet of reverse osmosis membrane group 6.
Because the water inlet of reverse osmosis membrane C15 is the condensed water of reverse osmosis membrane A7 and reverse osmosis membrane B11, the rate of recovery of whole reverse osmosis membrane group 6 has improved greatly.Generally speaking, when the rate of recovery of reverse osmosis membrane A7 and reverse osmosis membrane B11 is 33%, the rate of recovery of reverse osmosis membrane C15 is 25% o'clock, and the rate of recovery of reverse osmosis membrane group 6 can reach 50%.Because 33% rate of recovery of reverse osmosis membrane A7 and reverse osmosis membrane B11 is to meet the conventional design requirement, the rate of recovery of reverse osmosis membrane C15 is then lower and enough condensed water flow velocitys are arranged, to not having tangible influence in work-ing life of reverse osmosis membrane.This is than two current at present reverse osmosis membranes and connection or the more scientific and reasonable and safety of series connection use.
The dense water of flow-limiting valve group 20 enters the rate of recovery that flow has determined the reverse osmosis membrane group, we have increased by one the tunnel and have sent into the feedback network of high-pressure hydraulic pump 3 water-ins 4 through the needle-valve 26 of adjustable throttle amount in flow-limiting valve group 20, make the condensed water of reverse osmosis membrane group be utilized once more, can make the rate of recovery of total system increase 10-20% again, but this can not influence the rate of recovery of reverse osmosis membrane group.Because the former water of different quality is different to feedback Water reuse ratio, the setter that present embodiment selects adjustable needle-valve 24 and needle-valve 26 to utilize as feedback water again, the user can be according to local water source situation, and the ratio of suitably regulating two needle-valves makes the rate of recovery of whole water treatment system reach 60-70%.If source quality does not allow to use feedback water, only need needle-valve 26 closed and get final product, system recoveries rate at this moment is exactly the rate of recovery of reverse osmosis membrane group.
It is in order to guarantee the minimum flow of flow-limiting valve group 20, also can not cause owing to the too small damage that causes reverse osmosis membrane of condensed water flow even closed needle-valve 24 fully that set current limiting valve 25 is set.
