Water in contain heavy metal.
The working principle of water middle-jiao yang, function of the spleen and stomach ion fractionation device is：
Water enters from the entrance of separating flow tract, and under the action of attached collection electric field, the attached collection of cation in water is in attached collection electric field
Near negative electrode tab, the attached collection of anion in water is near attached collection electric field positive plate；Attached collection electric field uses impulse type voltage, making alive
When, attached collection is carried out to the ion in water, allows attached collection in the attached yin-yang collected near electric field positive/negative plate (when power-off) when voltage is not added
Enter the separation electric field of subsequent ion after plasma diffusing W,Mo；As long as the intensity of attached collection electric field, burst length, the spacing of pole piece, water flow
Speed is matched, and the attached collection of separation of progress zwitterion that can be effective reaches the initial position one of all charged ions
Cause (cation is near negative electrode tab)；Since different ions has different charges and different atomic weight, in normal water
Most of main cation is calcium (Ca2+ atomic weight be 20), magnesium (Mg2+ ion atoms amount be 20), sodium (Na+ atomic weight
For 11), there are also some other micro cations；But for especially in the water of heavy metal pollution, wrapping in the water of some pollutions
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
For 47), barium (Ba2+ atomic weight be 56), cadmium (Cd2+ atomic weight 48) etc. be.Different ions has different ratio lotuses, such as calcium
Ion ratio lotus is 2/20, cadmium ion 2/48, lead ion 2/82, therefore the ratio lotus of heavy metal ion is relatively small, especially
Lead, mercury etc., and cationic such as calcium and magnesium sodium common in general water compare than lotus it is larger.In identical separation electric field, phase
In the case of initial velocity, the mobile distance relation of the ion of not year-on-year lotus and the distance than proportional relationship, that is, moved than lotus and
Q/m is related, and under phase same electric field, the ion movement speed smaller than lotus is slow, as long as ensuring the heavy metal cation smaller than lotus attached collection
Near pole piece, it is ensured that bigger than lotus as calcium ions and magnesium ions also completely attached collection achieve the effect that complete attached collection on positive plate；
Consider effectively attached collection and is released effectively the factor of ion, the time (the attached collection of making alive) of the attached collection of pulsed power supplies<Release time is (no
Making alive)；Consider that too high voltages are easy to cause the electrolysis of water, therefore pays the utmost attention to the attached collection voltage of electric field and separation electric field of input
Voltage cannot be excessive, should be typically lower than 2V or less.
Identical electric field is different different Ion transfer abilities, is mainly determined according to different charged ratios,
Under identical uniform electric field, ion enters separation electric field under the drive of water flow, due to the effect of attached collection electric field before, so that
Cation is all near attached collection electric field negative electrode tab, so that the primary condition of cation is consistent, under the action of separating electric field, in water
Different ions can be migrated under the action of separating electric field, anion is moved to separation electric field positive plate, and cation can be to
The movement of electric field negative electrode tab is separated, but due to different ratio lotuses, the offset distance of different ions is not also identical.Calcium ions and magnesium ions exist in water
It being reached near ion isolation electric field negative electrode tab when near water outlet, for heavy metal ion due to smaller than lotus, movement speed is slow, because
This heavy metal ion has also been in elsewhere, by the diversion channel of water outlet, is shunted to water, so as to in water not
Same zwitterion is separated, and the shunting subexit that will be formed between first piece of split-flow baffles and second piece of split-flow baffles is passed through
It is denoted as detection outlet, so that it may by most of separation of heavy metal ions and detected.Attached collection electric field is to ion point in order to prevent
Influence from electric field, 2 electric fields need a certain distance, i.e., the front end of separation electric field positive plate not with attached collection electric field negative electrode tab
Between rear end have D spacing, D be greater than 0, separation electric field cathode leaf length it is identical as electric field anode leaf length is separated, D preferably with
It is identical to separate electric field cathode leaf length.
