Abstract
The sea water or bittern desalting method is to adopt sea water or bittern pipeline or other structure with two opposite magnetic poles. When sea water or bittern flows through the sea water or bittern pipeline or other structure with two opposite magnetic poles, the magnetic poles generate magnetic field and ions with net charges in between to arrest other ions to enter to. Thus, desalted water flows out of between the magnetic poles while concentrated salty water flows out from sides.
Description
The present invention relates to a kind of desalinizing seawater or the method for brackish water, especially a kind ofly utilize magnets magnetic fields to desalinize seawater or brackish water, and can make and desalinize seawater or the device structure of brackish water is extremely simple, cost is extremely cheap, use magnetism desalting method for seawater extremely convenient, that do not consume energy in the process of desalination.
The title of the traditional seawater that is widely used at present or the equipment of brackish water desalination method, technical process has a lot, but mainly contains by its flesh and blood branch: distillation method, electroosmose process and reverse osmosis method.Condensation method has appearred again recently, it is to utilize following principle: when the temperature of the unsaturated aqueous solution is reduced to zero pour, begin to separate out ice in the solution, the concentration of solution constantly increases, solution solidifies point constantly reduces, when the concentration of last solution reached the saturation concentration of this solute solution, ice and solute were separated out together.Because the energy consumption and the desalinating cost of this desalination method are too high, so its equipment does not put into production always.Distillation method is that heating makes the water molecules in the seawater evaporate condensation more earlier to seawater, the isolating desalination method of desalination water and salt.Electroosmose process is alternately to arrange having anode membrane and the cavity block of selecting perviousness, forms a plurality of separate compartments; The seawater that the seawater of compartment is desalinated with compartment is concentrated alternate being separated by, and under the effect of extra electric field, fresh water and condensed water are able to isolating desalination method.Reverse osmosis method is to utilize impressed pressure to make the water molecules of seawater see through the semi-permeable membranes that only allows solvent to see through, do not allow solute to see through, with the separated desalination method of seawater and freshwater.The desalination method that all these are traditional, complex structure, the manufacturing that all will expend a large amount of energy and desalting plant during desalination is difficult, maintenance cost height.In traditional desalination method, the reverse osmosis method energy consumption is minimum.Its energy consumption only is 1/2nd of an electroosmose process, 1/40th of distillation method.But the existing in the world at present accurately minimum current consumption of the saturating method desalting plant of seawater reverse osmosis energy consumption of report also reaches 6kwh/T, and this does not also comprise the energy consumption of maintenance facilities operation.Three kinds of traditional desalination method facility investments are all very high, and ten thousand tons of water factory's facility investment volumes are all at 8～1,000,000,000 circle Renminbi.
The objective of the invention is: a kind of new seawater or the desalination method of brackish water---magnetism desalting method for seawater are provided, it utilizes magnets magnetic fields to desalinize seawater or brackish water, and can make and desalinize seawater or the device structure of brackish water is extremely simple, cost is extremely cheap, it is extremely convenient to use, do not consume energy in the process of desalination.
The object of the present invention is achieved like this: have the hollow structure of the pipe culvert that can carry seawater or brackish water or identical function structure the relative magnet of two magnetic poles to provide pipe culvert or the identical function structure of magnetic induction line perpendicular to water (flow) direction magnetic field to it instead.Give magnet and magnet sidewall, pipe culvert or identical function inner structural wall that pipe culvert or identical function structure provide magnetic field, add the simplest desalination structural unit that baffle plate constitutes and can be divided into by its magnet number that has and magnet positions: two magnets desalinations unit, desalinate the unit in the middle of single magnet sidewall desalination unit and the single magnet.To be two magnets add baffle plate or two near two opposed inner walls in pipe culvert or the identical function structure or inwall and one in two magnets desalination unit adds baffle plate.Single magnet sidewall desalination unit is that a magnet adds baffle plate near pipe culvert or identical function structure one inwall or one in pipe culvert or identical function structure.In the middle of single magnet the desalination unit be a magnet two magnetic poles a sidewall of magnet itself and one add in the baffle plate or the two side of a sidewall of magnet itself and pipe culvert or identical function structure one side inwall or magnet itself in the centre.In three kinds of desalination structural units, polar vertical longitudinal cross-section is " trilateral " or camber line " trilateral " or other " trilateral ", and the flat shape of axis of the vertical line done to its pairing limit of the summit of the vertical longitudinal cross-section of the pairing magnetic pole of polar rib " trilateral " of the magnetic induction line correspondence that contacts the earliest of current and current or overlap.In two magnets desalination unit and single magnet sidewall desalination unit, magnet mostly is the vertical longitudinal cross-section of magnetic pole and is the magnet of " right-angle triangle " or " right-angle triangle " that hypotenuse is camber line, but also can be other " trilateral ".The pairing magnetic pole side, a limit of the limit of angle bead always of the vertical longitudinal cross-section of magnetic pole " right-angle triangle " or " trilateral " should or add baffle plate near pipe culvert or identical function inner structural wall or sidewall, and seawater or brackish water are not flowed betwixt; If magnetic pole and sidewall from, between two magnetic poles and should have the block filler of non-magnet material to flow betwixt between sidewall, two magnetic poles and the sidewall to prevent seawater or brackish water.The pairing magnetic pole side, another limit of another square edge of the vertical longitudinal cross-section of magnetic pole " right-angle triangle " or " trilateral " and flow to mutually " vertical " of seawater or brackish water, and what make that magnetic pole contacts current the earliest is the magnetic induction line of the pairing magnetic pole rib of the corresponding drift angle of this edge, and this drift angle should be as far as possible little.Side can allow seawater or brackish water level vertically flow between two magnetic poles at the place, the 3rd limit of the hypotenuse of the vertical longitudinal cross-section of magnetic pole " right-angle triangle " or " trilateral ".In two magnet desalinations unit, the level of two magnets vertically is that the axial location of pipe culvert or identical function structure is identical with vertical lengthwise position.In the desalination unit, polar vertical longitudinal cross-section mostly is " isosceles triangle ", or camber line " isosceles triangle ", but also can be other " trilateral " in the middle of single magnet; The pairing magnetic pole side, a limit of the end of polar vertical longitudinal cross-section " isosceles triangle " or " trilateral " and flow to mutually " vertical " of seawater or brackish water; What magnetic pole contacted current the earliest is the magnetic induction line of the pairing polar rib of the corresponding drift angle of this edge; This drift angle should be as far as possible little; Cross this summit on the vertical line that its corresponding sides are done, can add its height be between two magnetic poles in outage, grow for this summit to corresponding sides vertical line segment length, thickly approach as far as possible, be the baffle plate of conductor non-magnet material; Dual-side can allow seawater or brackish water axial flow therein between two magnetic poles and between two magnetic poles.In three kinds of desalination structural units, the magnetic pole side can allow seawater or brackish water flow therein, also can not allow it flow.Seawater flow to for the magnetic induction line of rib from magnetic pole in face of current to the water (flow) direction lateral magnetic induction line of magnetic pole of " vertical " mutually.Side between two magnetic poles or between two magnetic poles and water (flow) direction mutually the lateral same level of magnetic pole of " vertical " vertically pipe culvert is arranged the place; Pipe culvert is high to be the desalination structural unit internal cavity height that exists together, and wide is between two magnets or the width of magnetic pole and sidewall or magnetic pole and pipe culvert or identical function inner structural wall.In three kinds of desalination structural units, the also available permanent magnet of the both available electro-magnet of magnet.
In two magnets desalination unit, suppose that the magnetic induction line direction of two magnets is opposite, be one magnetic field to be arranged and do not have the interface in magnetic field at the allow side and two magnetic interpolar interfaces between seawater or brackish water mobile two magnetic poles of same magnet.Because the interface tilts,, will enter two magnetic interpolar ions and will successively progressively will stride across the interface if there is not magnetic field.When entering two magnets, seawater desalinates the zone flows of a magnet in unit two magnets, when the ion in the seawater strides across the interface, stride across a kind of ion in the yin, yang ion at interface, suppose it is positively charged ion, under the effect in magnetic field, will be forced to get back to the side that the interface does not have magnetic field; Since the interface be tilt, the magnetic induction line direction of two magnets is opposite in addition, the interface do not have the positively charged ion of magnetic field one side will show static charge and with two magnetic poles at adjacent interface between the face of side become surface charge to distribute.And with the negatively charged ion of the different electric charges of positively charged ion band, motion will show static charge between two magnetic poles will continuing under the effect in magnetic field, and and the positively charged ion that do not have the side in magnetic field to show static charge at the interface between two magnetic poles, produce electric field.Along with entering two magnetic interpolar negatively charged ion and not having the positively charged ion of magnetic field one side to increase at the interface, can be more and more stronger at two magnetic interpolar electric fields, only need account for 1/100000000000th ions of the number of ions in desalination structural unit seawater, just can make the magnetic induction B * seawater velocity V of the electric field strength E=magnet of electric field to part per trillion.This moment when negatively charged ion will be crossed over the interface and enters between two magnetic poles, with two magnetic poles at adjacent interface between the face of side become the positively charged ion of surface charge distribution will drag negatively charged ion, make negatively charged ion can not cross over the interface.When positively charged ion is crossed over the interface and has been entered field regions, electric field is weakened, magnetic field to cationic effect to extrapolation greater than electric field to cationic effect of inwardly dragging, make positively charged ion cross over the interface again and get back to no field regions.Therefore the yin, yang ion in the seawater all can not enter between two magnetic poles of this magnet, same reason, yin, yang ion in the seawater all can not enter between two magnetic poles of another magnet, makes between two magnets, the two magnetic poles impurity concentration the effusive seawater drop to original 1/100000000000th to part per trillion.East China sea saltiness is 3.5%, and the impure amount of Drinking Water in China standard is 0.05%.Therefore be pure water from effusive " seawater " between two magnetic poles of two magnets.When seawater flows in the desalination unit in the middle of single magnet sidewall desalination unit or single magnet, same mechanism, effusive between two magnetic poles also is pure water.
Owing to adopt above-mentioned theory structure, magnetism desalting method for seawater can not only become the desalination water of drinking water standard to seawater or brackish water desalination and also desalinize seawater or the device structure of brackish water is extremely simple, cost is extremely cheap, it is also extremely easy to use, desalinize seawater or the process of brackish water in do not consume energy.
