First water outlet of the water of the shunting subexit outflow formed between stream partition board as detection of heavy metal ion separator；Will from its
The water of excess-three shunting subexit outflow is mixed, the second water outlet as detection of heavy metal ion separator.
The operation principle of detection of heavy metal ion separator is：
Water enters from the entrance of separating flow tract, and under the action of detach electric field, cation in water is to detaching electric field cathode
Piece moves, 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 flow
Lower to enter separation electric field, the entrance of separating flow tract is positioned close to the front end of separation electric field negative plate so that all sun from
The primary condition of son is consistent, and under the action of detaching electric field, the different ions in water can be moved under the action of detaching electric field
It moves, anion is moved to separation electric field positive plate, and cation can be moved to separation electric field negative plate, 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+ atom
48) etc. amount is.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 moves
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, so as to be detached to zwitterion different in water, is passed through
Using the water of the shunting subexit outflow formed between second piece of split-flow baffles and third block split-flow baffles as heavy metal ion
Detect the first water outlet of separator；The water flowed out from its excess-three shunting subexit is mixed, as heavy metal ion
Detect the second water outlet of separator, so that it may by most of separation of heavy metal ions and detected, pass through detection the at this time
TDS values in one water outlet, so that it may to judge whether contain heavy metal ion in water；It is of course also possible to by by TDS sensors
The value of detected value and the 2nd TDS sensors compared, as long as two values are different, may also indicate that in water containing a huge sum of money
Belong to ion, and is shown by display screen.
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 3, wherein
First piece of split-flow baffles be with the distance between electric field positive plate is detached：

Or the length of separation electric field negative plate, 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 plate；Ranging from 1/15~1/8；In this way, calcium ion, sodium ion etc. than lotus 0 to 1/15~
The shunting subexit stream that metal cation between 1/8 can be formed between first piece of split-flow baffles and separating flow tract inner wall
Go out；
Second piece of split-flow baffles be with the distance between electric field positive plate is detached： Ranging from 1/28~1/20；In this way, the gold than lotus between 1/15~1/8 to 1/28~1/20 such as silver ion, cadmium ion
Belong to 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 are with the distance between electric field positive plate is detached： Ranging from：1/45~1/40；In this way, barium ions, lead ion, mercury ion etc. than lotus 1/28~1/20 to 1/45~1/
The shunting subexit that metal cation between 40 can be formed between second piece of split-flow baffles and third block split-flow baffles
Outflow.
At this point, the water of the shunting subexit outflow formed between second piece of split-flow baffles and third block split-flow baffles is made
For the first water outlet of detection of heavy metal ion separator, whether heavy metal ion can be contained in more accurate effectively detection water.
Embodiment three
Unlike embodiment two, split-flow baffles are shown in Figure 4 equipped with two pieces, wherein：
First piece of split-flow baffles be with the distance between electric field positive plate is detached：Its
Middle K be less than 1 be more than 0 constant, voltages of the U for the second external stabilized power positive and negative anodes between, l be detach electric field positive plate or
The length of electric field negative plate is detached, v is the water velocity that water flows through separating flow tract, and d is separation electric field positive plate and separation electric field
The distance between negative plate；Ranging from 1/15~1/8；
Second piece of split-flow baffles be with the distance between electric field positive plate is detached： Ranging from 1/45~1/40.
At this point, the water of the shunting subexit outflow formed between first piece of split-flow baffles and second piece of split-flow baffles is made
For the first water outlet of detection of heavy metal ion separator, also accurately effectively can detect in water whether contain heavy metal ion.
