Abstract

A process for separating the solvent from solute in electrolyte is disclosed. The orthogonal and alternative electric field and magnetic field are applied to a container of electrolyte solution to make to cations and anions to do reciprocating oscillation under the action of electric field while said cations and anions are acted by Lorentz force. Regulating the frequency and phase of electric field and magnetic field can make the anions and cations to move in opposite directions for separating them from each other.

Description

Synchro-alternating electromagnetic field type liquid ion pump

Technical field the present invention is a kind of solvent solute separation method with liquid electrolyte solution.

The solvent solute of technical background electrolyte solution all needs in separating in a lot of fields, concentrates or the like as desalinization, sewage disposal, chemical industry solutions.

Present method mainly contains distillation, ion-exchange, counter-infiltration or the like.Distillation needs to use a large amount of energy, incompatible energy-intensive situation at present; Ion-exchange is usually used in water correction, the removal of heavy metal ion, but its essence is to use some harmless ions to reach for some harmful ions, and can not remove all ions, also need constantly to use chemical agent; Counter-infiltration is a kind of new effective deionization process, and its basic principle is by membrane filtration, but for some undersized inorganic matter ions, very high to the requirement of film, and the consume of film is also very fast.The process that the water-soluble and ionization of most material goes out ion does not absorb or emits heat, therefore sees in theory only to separate that a spot of energy of needs remove to overcome Entropy Changes to them from solvent, and does not need to consume lot of energy.The ion that the present invention adopts electromagnetic field to drive in the solution reaches the purpose of separating the solvent solute.Summary of the invention has proposed the method for solvent and solute in a kind of new separate electrolyte solution.Generally all can ionization produce negative ions after electrolyte is water-soluble, ion might combine with water and produce hydrated ion, but generally speaking ion can move freely.Because the distribution of negative ions keeps evenly substantially, so solution keeps electroneutral.When external electrical field applies on the aqueous solution of polar molecule, thereby at first be that hydrone produces orientation polarization and offsets a part of electric-field intensity; Negative ions in the solution moves a small distance in the opposite direction then, and the electric charge center of gravity of ion no longer overlaps like this, and this displacement polarization also can produce an electric field to offset a part of electric field.System's state that can restore balance again after polarization is finished.When the electric field on being applied to solution was the electric field of an alternation, the ion in the solution can be made double vibrations along with what electric field did not stop.When applying electric field, also on the direction of vertical electric field, apply to solution one with electric field with frequently alternating magnetic field.When the direction of motion of ion changed, the direction in magnetic field also changed, and the Lorentz force that is subjected to of ion is toward the direction all the time like this.Ion is slowly assembled towards one side of solution motion under the effect of this power, till the diffusion motion of this motion and ion reaches balance.Realized that finally electrolytical concentration is high low in the solution on one side on one side, reached concentrated effect.

For hydrone, the polarization in electric field mainly is orientation polarization, and the polarization of ion mainly is a displacement polarization, because time of orientation polarization is very short, and that the time of displacement polarization is compared is much longer.So can not cause hydrone resonance when applying an alternating electromagnetic field, thereby avoid big energy is passed to water by ion resonance.Having only minute quantity energy transmission feedwater during whole device work, do not have the consumptive material loss, is a kind of separation method efficiently.

The method that has many trials to use electric fields or magnetic field or the combination of the two to desalinize seawater in the existing patent documentation, but thereby they all claim and will separate and assemble the purpose that reaches desalination water to zwitterion by electric field force or Lorentz force.But avogadros constant is too big, even want the zwitterion of ppm concentration level is separated, the electric-field intensity or the Lorentz force that need also all can't reach far away, and the aqueous solution is also breakdown already under such electric-field intensity.

Description of drawings

Fig. 1 is the principle of compositionality schematic diagram of ionic pump;

Fig. 2 is the spiral cavity figure of ionic pump.

The specific embodiment is described in further detail the present invention below in conjunction with each accompanying drawing:

Fig. 1 is the principle of compositionality schematic diagram of ionic pump, and 1 is battery lead plate, and 2 for being loaded with the cavity of solution, and 3 is electromagnet.As shown in FIG., switch on to battery lead plate, when electric pole plate is anodal, when lower electrode plate is negative pole, can move downward by the cation in the effect solution of electric field force, anion moves upward, if this moment magnetic direction left, according to left hand rule, negative ions all can be subjected to a Lorentz force that vertical paper is inside.The same direction that changes electric field, when electric pole plate is a negative pole, when lower electrode plate be anodal, the ion motion direction can be oppositely, if at this moment that magnetic direction is also reverse, according to left hand rule, negative ions can be subjected to a Lorentz force that vertical paper is inside equally.The direction in so continuous change electric field and magnetic field, negative ions are vibrated the reciprocating while constantly to the inside direction motion of vertical paper.Though the motional amplitude of ion is very little, if vibration is rapid, repeatedly be subjected to the effect of unidirectional Lorentz force, its effect is accumulated in and can makes ion constantly to a direction motion together.If the change frequency of extra electric field equals the resonant frequency of ion, the reciprocating amplitude of ion will reach maximum, and the Lorentz force that is subjected in the motion also for for maximum, can make ion assemble to an end with the fastest speed like this.

In order to make cavity two ends solution ion concentration difference reach bigger value, the cavity of splendid attire solution is made long screw type.As shown in Figure 2: 21 is the chamber outer wall electrode, and 22 is the flat conducting film of soft magnetic bodies outside, and 23 are the insulation cavity, and 24 is the cavity inner wall electrode, and 25 is soft magnetic bodies.Electric field is added on two electrodes of inside and outside wall, and ion will vibrate along the radial direction of spiral cavity.Soft magnetic bodies plays the effect that increases magnetic field intensity and retrain the magnetic line of force, allow the magnetic line of force as much as possible pass cavity.The flat conducting film of soft magnetic bodies outside passes to alternating current, makes soft magnetic bodies produce magnetic field, and the magnetic line of force axially passes cavity along spiral cavity, so the Lorentz force that ion is subjected to will be along the hand of spiral of spiral cavity.Original solution to be separated is from middle introduction chamber body, and concentrated solution and weak solution flow out from two ends.The cavity of screw type can be bent to end to end tire-like for the magnetic circuit that forms a closure with the leakage that reduces magnetic field simultaneously.

Because the electrodynamic capacity of whole electromagnet is bigger, so the magnetic field of its generation is difficult to sudden change.Therefore at first find the resonant frequency of required separation solution intermediate ion, then with high-power MOS tube as switch, with the ion resonance frequency is switching frequency, direct current is cut into square wave to lead on the electromagnet, an electric capacity in parallel obtains stronger alternating magnetic field to adjust power factor at the electromagnet two ends simultaneously.The change of magnetic field electric field is much easier relatively, because the equivalent capacity of device is less.So adopt electric field to follow the method in magnetic field, very little resistance of series connection can be judged sense of current with the voltage at comparator comparison resistance two ends on electromagnet, determines the direction of electric field thus, thereby reaches the synchronous of electric field and magnetic field.
