Description
Technical field
The present invention relates to a kind of ion fractionation devices, for separating to the cation in the water flowed through in the device.
Background technique
The water process mode of water purifier mainly relies on the form of film to be handled at present, and a kind of film relies on the mode of filtering
Pollutant is retained, such as PP cotton, active carbon, another film is shunted after filtering, such as reverse osmosis, ultrafiltration, a part of mistake
Water after filter is discharged as purified water, and another part is just discharged with pollutant as waste water.Water purifier is typically all
The process of entire Water warfare is completed by dividing multistage filtering.Main core filter membrane is divided into ultrafiltration, reverse osmosis currently on the market
Both saturating films.Ultrafiltration membrane can retain the minerals in water but cannot cross the heavy metal ion in drainage, and reverse osmosis membrane can be with
The ion of the overwhelming majority is filtered out, but does not have mineral ion, is become or close to pure water.There is part using nanofiltration, protects
Certain mineral ion is stayed, but most of heavy metal ion can be filtered out.But either any film all has following several
A common characteristic:
1, the effect filtered is fixed, i.e. the aperture of film determines the filter effect of film, and film once forms, also just solid
The aperture for having determined filtering, does not adapt to different occasions;
2, the filter effect of film uses time president with film, and efficiency becomes low, and aperture becomes smaller, with using the time to add
It is long, it can may also block, finally be also possible to that film is caused to fail, need replacing film;
3, film is by micro porous filtration, and micropore will form certain water resistance, and aperture is smaller, water resistance is bigger, it is however generally that,
Reverse osmosis membrane can filter whole ions, form pure water, aperture is minimum, thus water resistance is also maximum, and reverse osmosis water purifier is general
It requires booster pump to be pressurized water inlet, just can guarantee certain water yield.
Summary of the invention
The technical problem to be solved by the present invention is to provide no matter one kind uses length of time all for the above-mentioned prior art
It can guarantee the water middle-jiao yang, function of the spleen and stomach ion fractionation device of service efficiency.

Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
Embodiment one
Water middle-jiao yang, function of the spleen and stomach ion fractionation device as described in Figure 1 comprising
Separating flow tract 1, separating flow tract have entrance and exit;
Electric field positive plate 2 is separated, is arranged in separating flow tract, close to the outlet of separating flow tract, with external stabilized power
Anode connection;
Electric field negative electrode tab 3 is separated, is arranged in separating flow tract, close to the outlet of separating flow tract, with external stabilized power
Cathode connection;
The entrance of separating flow tract is positioned close to the front end of separation electric field negative electrode tab;
The outlet of the separating flow tract is formed between separation electric field positive plate rear end and separation electric field negative electrode tab rear end,
And the outlet of separating flow tract is equipped with the split-flow baffles 6 of N block uniform intervals setting parallel with electric field negative electrode tab 3 is separated, to will divide
It is divided into the identical shunting subexit of N+1 amount of capacity from the outlet of runner, the value of N is natural number, N=3 in the present embodiment,
Certainly, N can take the arbitrary value in natural number.
Water enters from the entrance of separating flow tract, and under the action of separate electric field, cation in water is to separating electric field cathode
Piece is mobile, and the anion in water is in separation electric field positive plate movement.Consider that too high voltages are easy to cause the electrolysis of water, therefore excellent
First consider that the separation voltage of electric field of input cannot be excessive, should be typically lower than 2V or less.Identical electric field moves different ions
Shifting ability is different, and is mainly determined according to different charged ratios, under identical uniform electric field, drive of the ion in water flow
It is lower enter separation electric field, the entrance of separating flow tract be positioned close to separation electric field negative electrode tab front end so that it is all sun from
The primary condition of son is consistent, and under the action of separating electric field, the different ions in water can be moved under the action of separating electric field
It moves, anion is moved to separation electric field positive plate, and cation can be moved to separation electric field negative electrode tab, since different ions has
Different charges and different atomic weight, it is calcium (Ca that main cation is most of in normal water2+ atomic weight be 20), magnesium
(Mg2+ ion atoms amount be 20), sodium (Na+ atomic weight be 11), also some other micro cation;But for some
In the water of pollution, especially in the water of heavy metal pollution, a large amount of heavy metal ion is contained, such as lead (Pb2+ atomic weight be
82), mercury (Hg2+ atomic weight be 80), silver (Ag2+ atomic weight be 47), barium (Ba2+ atomic weight be 56), cadmium (Cd2+ atomic weight
48) etc. for.Different ions has different ratio lotuses, if calcium ion is 2/20 than lotus, cadmium ion 2/48, and lead ion 2/
82, therefore the ratio lotus of heavy metal ion is relatively small, especially lead, mercury etc., and cation such as calcium and magnesium common in general water
Sodium etc. compares larger than lotus.Therefore, in identical separation electric field, identical initial velocity, the ion of not year-on-year lotus is mobile
Distance relation to than lotus, than proportional relationship, that is, the distance moved is related to q/m, under phase same electric field, the cation bigger than lotus
Movement speed is fast, and the cationic movement speed smaller than lotus is slow;Especially heavy metal ion is due to, movement speed smaller than lotus
Slowly;By the diversion channel of water outlet, water is shunted, is effectively divided so as to the cation to lotus not year-on-year in water
From.
Embodiment two
What is different from the first embodiment is that three pieces of split-flow baffles are not evenly spaced on, it is shown in Figure 2, wherein

Or the length of separation electric field negative electrode tab, v are the water velocity that water flows through separating flow tract, d is separation electric field positive plate and separation electricity
The distance between field negative electrode tab;Range be 1/15~1/8;In this way, calcium ion, sodium ion etc. are than lotus 0 to 1/15~1/
The shunting subexit stream that metal cation between 8 can be formed between first piece of split-flow baffles and separating flow tract inner wall
Out;
Second piece of split-flow baffles with separate the distance between electric field positive plate are as follows:
Range be 1/28~1/20;In this way, the metal than lotus between 1/15~1/8 to 1/28~1/20 such as silver ion, cadmium ion
The shunting subexit outflow that cation can be formed between first piece of split-flow baffles and second piece of split-flow baffles;
Third block split-flow baffles with separate the distance between electric field positive plate are as follows:
Range are as follows: 1/45~1/40.In this way, barium ions, lead ion, mercury ion etc. than lotus 1/28~1/20 to 1/45~1/40 it
Between metal cation can be formed between second piece of split-flow baffles and third block split-flow baffles shunting subexit outflow.
The embodiment can be precisely separated the cation of not year-on-year lotus.
Embodiment three
Unlike embodiment two, split-flow baffles are shown in Figure 3 equipped with two pieces, in which:
First piece of split-flow baffles with separate the distance between electric field positive plate are as follows:
