Description
Technical field
The utility model is related to a kind of water purifiers.
Background technology
The water process mode of water purifier is mainly to be handled by the form of film at present, and a kind of film relies on the mode of filtering
Pollutant is retained, such as PP cottons, activated 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 is once molded, also just solid
The aperture for having determined filtering, does not adapt to different occasions；
2, the filter effect of film becomes low with film usage time president, efficiency, and aperture becomes smaller, with usage time plus
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 can 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 is required for booster pump to be pressurized water inlet, just can guarantee certain water yield.

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.

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；In this way, calcium ion, sodium ion etc. than lotus 0 to 1/15~1/8
Between metal cation can be formed between first piece of split-flow baffles and separating flow tract inner wall shunting subexit outflow；
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 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 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 1/45~1/40 it
Between metal cation can be formed between second piece of split-flow baffles and third block split-flow baffles shunting subexit 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, with
And the content of heavy metal ion.
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；
