As shown in Figure 2, each parts of the waste water-free reverse osmosis water purifier of embodiment 1 can connect in the following manner:
Go up at main water supply tube (in tap water is arranged) and to connect a water service pipe 1, water service pipe 1 be connected in series successively pretreater 2, low-tension switch, first topping-up pump 4 and dark treater form the water inlet water route, and low-tension switch can prevent the anhydrous idle running damage water pump of water pump.Wherein pretreater 2 is made up of three preprocessing filter element that connect that are one another in series.Establish reverse osmosis membrane assembly in the dark treater, reverse osmosis membrane is divided into pure water district 5 and dense pool 6 with dark treater, and pure water district 5 is communicated with the pure water rising pipe, is used to obtain pure water.The import in dense pool 6 links to each other with the outlet of first topping-up pump 4, the outlet in dense pool 6 is connected with the water cavity of energy storage canister 9, energy storage canister 9 is used for collecting, storing the dense water of discharging from dark treater, energy storage canister is provided with water cavity 10 and air cavity 11, is provided with barrier film between air cavity and the water cavity so that prevent gas dissolving and discharges the gas reserves that reduce in the air cavity with current in water.In addition, water cavity 10 is connected with first electrically-controlled valve 12, first check valve 13 successively by connecting pipeline, finally be connected on the water service pipe 1, form discharge pipe line, first check valve 13 can prevent that source water from oppositely flowing directly into energy storage canister 9, the concentrated stream that the air pressure that stores in the above-mentioned air cavity can be in the water cavity 10 of energy storage canister 9 provides energy to water service pipe 1, on the water outlet of water cavity 10 and the pipeline between first electrically-controlled valve 12, draw on return line to the first topping-up pump 4 inlet ductwork, on this return line, establish waste water than 8 (throttling set a kind of).
The working process of embodiment 1 is as follows:
First electrically-controlled valve 12 can be for often opening electrically-controlled valve, when in main water supply tube, water being arranged, low-tension switch is in closure state under the hydraulic pressure effect, if start water manufacturing system system water this moment, then connect the power source circuit of first topping-up pump 4 and the circuit of first electrically-controlled valve 12, so 4 energisings of first topping-up pump start, first electrically-controlled valve 12 is closed; From the water in the main water supply tube through three preprocessing filter element (being pretreater) pre-treatment again after the supercharging of first topping-up pump, enter reverse osmosis filter core (being dark treater) and carry out advanced treatment; Be pure water from the effusive water of reverse osmosis filter core water outlet (being 5 outlets of pure water district); Flow into the water cavity 10 of energy storage canister 9 from reverse osmosis filter core concentrated water discharge mouth (being 6 outlets of the dense pool) water of discharging, after waste water is than 8 decompressions, flow back to the water-in of first topping-up pump 4 again, thereby obtain recycle once more.
When system water finishes, first topping-up pump 4 and 12 outages of first electrically-controlled valve, be that topping-up pump while first out of service electrically-controlled valve 12 is opened, at this moment, dense water in the energy storage canister water cavity 10 flows into water service pipe 1 and then flows into main water supply tube (generally speaking through first electrically-controlled valve 12 and first check valve 13, this moment, the energy storage canister internal pressure was higher than the source water pressure), the user is in the upstream of main water supply tube or downstream when opening water tap, and dense water will be discharged for undrinkable water thereupon and be used.
When beginning to the next system water cycle, because the water in the energy storage canister water cavity 10 seldom or do not have, after the startup of first topping-up pump and first electrically-controlled valve are closed, the flow that exports the dense water of discharging from dense pool 6 can be very big, but this moment, the hydraulic pressure in dense pool was less, the very big effect (this moment, filtration yield was less) that the high strength flushing occurs of the tangential mobile discharge of dense water one side of reverse osmosis membrane of will feasible flowing through may sedimentary tamper so that effectively wash away the film surface.Carrying out along with flushing process, hydraulic pressure in the energy storage canister water cavity 10 can rise gradually, the tangential discharge of dense water one side of the reverse osmosis membrane of flowing through can descend gradually, flow velocity reduces gradually, the water that water in the energy storage canister water cavity 10 or 6 outlets of dense pool are discharged can strengthen than the flow that is back to the first topping-up pump water-in after reducing pressure gradually by waste water, the pressure in dense pool rises gradually, and the reverse osmosis filter core begins normal drainage after this flow rises to normal value.
Certainly, first electrically-controlled valve 12 also can be normally closed electrically-controlled valve, if use normally closed electrically-controlled valve, its control of turning need be adjusted accordingly in the process of system water-flushing-make again water, is not described in detail in this.
The maximum moisture storage capacity of energy storage canister 9 can consider and can often the concentrated water drainage in the energy storage canister be gone out that the concentration of dense water can be too not high less than 4L, so volume can be smaller to reduce manufacturing cost, preferably less than 2L.
With respect to prior art, the use of the energy storage canister of embodiment 1 has realized the recycle of dense water, does not produce the waste water of discharging, has both saved water resources, has avoided the installation of wastewater discharge pipe again; Because the recycling of dense water, system can not need independent flushing reverse osmosis membrane program, and only needs when making water next time and begin by making the reverse osmosis membrane surface bigger tangential flow velocity of current of flowing through realize the flushing of reverse osmosis membrane; Water purifier of the prior art has only during water 1/4th water to obtain utilizing in system, and have 3/4ths water as discharge of wastewater outside system, but this discharge water of 3/4ths still needs to carry out the processing of preprocessing filter element, therefore the utilization ratio of preprocessing filter element is lower, has had a strong impact on its work-ing life.And above-mentioned 3/4ths flooding velocity can be effectively shared in the design of the return line of embodiment 1, therefore can effectively prolong the work-ing life of preprocessing filter element.
As shown in Figure 3, the annexation of each parts of the waste water-free reverse osmosis water purifier of embodiment 2 is similar to Example 1, different is that waste water is replaced with second topping-up pump 14 than 8, and link position is different, the i.e. import of second topping-up pump 14 is connected on the water outlet of energy storage canister water cavity 10, and its outlet is connected on first topping-up pump, 4 export pipelines.Than embodiment 1, use second topping-up pump 14 can further promote the tangential discharge of dense water one side of the reverse osmosis membrane of flowing through, and flow is more stable.
Of particular note, the foregoing description 1,2 has all used first topping-up pump 4 on suction culvert, and this is lower at source water pressure (being tap water pressure), is not enough to overcome design under the situation of resistance of reverse osmosis membrane.And when the source water pressure is big, then need not to use this first topping-up pump 4, specific embodiment sees also following embodiment 3,4.
