To enable the above objects, features and advantages of the present invention to be clearer and more comprehensible, preferred embodiment is cited below particularly, and cooperate
Appended attached drawing, is described in detail below.
Detailed description of the invention
In order to illustrate the technical solution of the embodiments of the present invention more clearly, below will be to needed in the embodiment attached
Figure is briefly described, it should be understood that the following drawings illustrates only certain embodiments of the present invention, therefore is not construed as pair
The restriction of range for those of ordinary skill in the art without creative efforts, can also be according to this
A little attached drawings obtain other relevant attached drawings.
Fig. 1 shows a kind of structural schematic diagram of EDR desalination system provided in an embodiment of the present invention.
Diagram：10-EDR desalination system；110-EDR membrane stack.
Specific embodiment
Below in conjunction with attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Usually exist
The component of the embodiment of the present invention described and illustrated in attached drawing can be arranged and be designed with a variety of different configurations herein.Cause
This, is not intended to limit claimed invention to the detailed description of the embodiment of the present invention provided in the accompanying drawings below
Range, but it is merely representative of selected embodiment of the invention.Based on the embodiment of the present invention, those skilled in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
It should be noted that：Similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined in a attached drawing, does not then need that it is further defined and explained in subsequent attached drawing.Meanwhile of the invention
In description, term " first ", " second " etc. are only used for distinguishing description, are not understood to indicate or imply relative importance.
Fig. 1 is please referred to, is a kind of structural schematic diagram of EDR desalination system 10 provided in an embodiment of the present invention, the EDR desalination
System 10 is installed in water purifier, and the voltage swing for being mainly used for controlling in EDR membrane stack 110 or pressing time are to realize to water
Clean-up effect, to guarantee that user's uses water quality.
The EDR desalination system 10 includes control unit (not shown) and multiple EDR membrane stacks 110, each EDR membrane stack
Multiple runners are provided in 110, which includes at least one first fluid channel and a second fluid channel.It is multiple
EDR membrane stack 110 is connect with the intake tunnel of water purification system, and when water flows into multiple EDR membrane stacks 110, which will divide
Voltage swing or the pressing time of each EDR membrane stack 110 are not controlled, so that each EDR membrane stack 110 exports different degree of purifications
Clean water.
In other words, the control unit can according to user demand control EDR membrane stack 110 voltage swing or pressing time with
Output meets the water of the degree of purification of user demand, and if user needs wash vegetables, then the degree of purification of the water needed at this time is not high, then
The voltage of control unit control EDR membrane stack 110 is smaller or pressing time is shorter, so that the degree of purification of water is not high, but is saving
In the case where the energy, the demand of user's water for washing vegetables is met just.For another example, user needs to drink water, then the water needed at this time
Degree of purification is higher, then the voltage of control unit control EDR membrane stack 110 is larger or pressing time extends, so that the purification journey of water
Degree is higher, is required with meeting user's drinking-water.
In addition to this, since the control system includes multiple EDR membrane stacks 110, which can also be simultaneously to multiple EDR
The water purification process of membrane stack 110 is controlled, and the voltage that can control a part of EDR membrane stack 110 such as the control unit is larger or adds
Press the time longer, with the higher water of output purity, meanwhile, the voltage which controls another part EDR membrane stack 110 is lower
Or pressing time is shorter, with the lower water of output purity, under the premise of energy saving, to meet the miscellaneous need of user
It asks.
Readily comprehensible, the clean water that the EDR membrane stack 110 purification obtains will be by first fluid channel, i.e. clean water is logical
Road is exported to user, and the water comprising impurity will be excluded by second fluid channel, i.e. dirty water channel with used for other purposes.In addition, control
Unit processed not only can carry out pressurized purge to the water in EDR membrane stack 110 in the case where the water flowing in EDR membrane stack 110, also
It can be in the case where the water in EDR membrane stack 110 be static, to the carry out pressurized purge in EDR membrane stack 110, as user does not make
When with water purifier, a part of water can have been purified in advance, when user need using when can be used directly.The control system
DC power supply or AC power source can be used in power supply, and more preferably, the power supply of the control system is no more than 36 volts.
When water purifier is used for a long time, the impurity in some water will be adhered in the runner of the EDR membrane stack 110, therefore, to this
It is very necessary that EDR membrane stack 110, which periodically clean,.Its specific cleaning mode is：
The control unit also can control the voltage direction of the EDR membrane stack 110 in the given time with voltage direction phase before
Instead, so that the ion in water moves in the opposite direction, and then purified pure water will no longer be flowed out from clean aquaporin,
But flowed out from dirty water channel, to be rinsed to dirty water channel, the blocking of dirty water channel impurity or impurity is avoided to attach to dirty water
On the inner wall in channel, simultaneously because pure water will be continuously flowed in the given time in dirty water channel, so that logical to dirty water
The flushing effect in road is more preferable.Further, due to the voltage reversal in control unit control intake tunnel, then one side pure water
Dirty water channel will be flowed into, another aspect dirty water will also flow into clean aquaporin, do in order to avoid the dirty water comprising impurity flows into
Clean aquaporin is polluted, or even flows directly into user by water purification channel, the voltage in control unit control intake tunnel
When reversed, the valve that will also control the inlet of clean aquaporin is closed, and to prevent dirty water from flowing into clean aquaporin, is generated not
The consequence of benefit.
It can be seen that a kind of EDR desalination system provided in an embodiment of the present invention, is controlled in EDR membrane stack by control unit
Voltage swing or pressing time obtain the water of different degree of purifications, on the one hand saved the energy, on the other hand met user
Individual demand has reached more preferable matching effect.
In conclusion a kind of EDR desalination system provided in an embodiment of the present invention, the control system include control unit and
Multiple EDR membrane stacks, multiple runners are provided in each EDR membrane stack, and the runner includes at least a first fluid channel and one
A second fluid channel.When water flows into EDR membrane stack, control unit controls the voltage swing in each EDR membrane stack respectively or adds
The pressure time makes each EDR membrane stack export the clean water of different degree of purifications, flows into first fluid channel and exports to user, with full
Sufficient user needs the demand of the water of different degree of purifications, control unit also control the water comprising impurity flow into second fluid channel into
Other purposes of row.It can be seen that when in the present solution, control unit is by adjusting the different voltage swing of EDR membrane stack or pressurization
Between make EDR membrane stack export the clean water of different degree of purifications, be more able to satisfy the different water demand of user, while saving money
