Description
Technical field
There is electricity the present invention relates to field, salting liquid is particularly isolated alkali and acid by electrochemistry.Contain in sodium chloride solution
There are Na, Cl, H, the OH ions present invention is by electric field and ionic membrane by Na, and OH is enriched to and forms alkali together, Cl,
H is enriched to forms acid together.
Background technology
Solution acidic, neutrality or alkaline basis for estimation are：The relative size of [H] and [OH] concentration is in any temperature
Solution [H] when spending>In acidity when [OH], in neutrality, [H] during [H]=[OH]<In alkalescence but as [H in solution when [OH]
], [OH] it is smaller when, directly represent that solution acid-basicity is strong and weak with [H], [OH] magnitude relationship and just seem that very inconvenient is
It is from what is calculated with hydrogen ion concentration negative power index cumbersome, biochemist Zebulon of Denmark it is gloomy suggestion in 1909 by this
The numerical value that inconvenience is used is replaced with logarithm, and is defined as " pH ".The common logarithm negative value that pH is hydrogen ion concentration is mathematically defined,
I.e.：pH=-lg[H⁺].
In normal temperature（25℃）Under pressure, the aqueous solution of pH=7（Such as：Pure water）For neutrality, because water is in normal temperature
The hydrogen ion and the product of hydroxide ion concentration gone out with spontaneous ionization under pressure（The ion-product constant of water）All the time it is 1 × 10
¹4, and the concentration of two kinds of ions is all 1 × 107mol/L.Concentration of the small explanation H of the pH value concentration more than OH, therefore solution acidic
By force, and pH value increase then illustrates that H concentration is less than OH concentration, therefore solution alkaline is strong.So pH value is smaller, the acidity of solution
It is stronger；PH is bigger, and the alkalescence of solution is also just stronger.
Cationic membrane is typically sulfonic acid type, with fixed group and the ion such as sodium form sulfonic acid type that can be dissociated:Fixed base
Group is that sulfonate radical dissociating ions are sodium ions, and cation-exchange membrane can be regarded as a kind of polyelectrolyte, his macromolecule
Parent be it is undissolved, and the sulfonic acid group being connected on parent with negative electrical charge and can dissociating ions attract each other, they
With hydrophily because anode membrane is negatively charged, although original dissociation cation is dissociated in water by hydrone effect, in film
We are powered by electric field action outside, and the cation with positive charge just can be by anode membrane, and anion is because the same sex is repelled
And can not pass through, so with selective penetrated property.
Anion-exchange membrane is that a class contains basic activated group, the high molecular polymerization to anion with selective penetrated property
Thing film, also referred to as ion-selective permeability film.Anion-exchange membrane is made up of three parts：Main polymer chain with fixed group
That is macromolecule matrix（Also referred to as basement membrane）, lotus positive electricity active group（That is cation）And can be moved freely on active group
Anion.
The content of the invention
There are Na, Cl, H in sodium chloride solution, the OH ions present invention is by electric field and ionic membrane by Na, OH
It is enriched to and forms alkali together, Cl, H is enriched to forms acid together.
As shown in Figure 1
Coil 1 is the coil that salt solution is made, and produces direct electromotive force. in the magnetic field for placing change, direct electromotive force. is forced in solution
The ion displacement in face.Assuming that the sense of current is that then cation is moved clockwise clockwise, anion is moved counterclockwise.Then have
The cation in salt area 3 enters alkali area 5 by cationic membrane 4, and the anion-permeable anionic membrane 6 in pool 7 enters alkali area 5, pool 7
Cation permeable cationic membrane 10 enter sour area 8, the anion in salt area 2 leads to anionic membrane 9 and enters sour area 8.By ion
Displacement and obstruction so that the alkali in alkali area 5 is continuously increased so that the acid in sour area 8 is continuously increased.Salt area 2, salt area 3, coil is all
It is to be made up of salt solution, alkali area 5 is made up of alkali lye, sour area 8 is made up of acid solution, and pool 7 is made up of pure water liquid.
Coil 1 produces the method 1 of DC voltage
If Fig. 2 is the schematic diagram of commutator transformer
In U1Voltage effect under, according to n in law of electromagnetic induction formula e=- n (d Φ)/(dt) formula be coil turn, ΔΦ
For magnetic flux change amount, unit Wb, Δ t is changes the time used, and unit is s.ε is the induced electromotive force produced, unit
For V.Coil L2Necessarily induce and U1The induced voltage equally changed.U1It is a pulsating direct current L2Necessarily induce and U1Equally become
The induced voltage of change.
Coil 1 produces the method 2 of DC voltage
If Fig. 3 is dc motor fundamental diagram
Direct current enters the coil of rotor 21 by brush and commutator, and rotor, which is rotated in stator circle 23 and can produce one, voltage wave
Dynamic direct current.
