(100~8000 Gauss).The structure snd size of magnet body other aspects can use different designs as needed.
The magnetic direction that magnetic field feedway 6 is formed should be vertical with the injection direction of jet port 4.The S poles of magnet and N poles
The opening formed between end face answers face jet port 4.S poles and the placing direction of N poles should make its magnetic field to being sprayed from jet port 4
The particle of the positive and negative charge of band out is moved toward one another by Lorentz force, such as：When the cathode of animating electrode 3 is in left side, sun
Pole should be directing forwardly magnetic induction line at right side, i.e., on hand, S poles are a long way off for N poles.In addition, magnet body must not be kept off in itself
On jet flow running route with positive and negative charge particle or the work of other components is interfered to run.
Collecting region, in the underface of jet port 4, is divided into brine collection area and fresh water collecting area in collecting chamber 8.
Brine collection area is between two jet ports 4 and placed in the middle；Its collection port is generally side upwardly facing jet port 4, shape
Shape, the length of side on two 4 line directions of jet port are generally 1/2~3/4 of distance between two jet ports 4, side normal thereto
Upward length corresponds generally to the hole distance between magnet two-stage.Fresh water collecting area is located at the periphery or two in brine collection area
Side, for collection port towards upwards, the tight-lipped neighbour of collection is herded in inside with brine, and the shape in outside can take different designs from size,
But all ejection water outside Ying Shi brine collections area enter wherein.The structure snd size of each collecting region water storage cavity can be according to need
To use different designs.The connection that the structure of the interface of brine outlet and water outlet should meet correlation output pipeline will
It asks, and its mechanical strength need to ensure self structure safety in the operating condition.The making material of each component is all in collecting chamber 8
Should be corrosion-resistant, non-conductive, non-magnetic.
Dynamical system provides electric power and fluid for the operation of device and drives power, including for animating electrode 3, electromagnet (when
During using electromagnet) DC power supply electric power is provided, it is carried for brine water, the fresh water of output and strong brine, the conveying of compressed air
For power.The performance indicator of associated components and equipment must meet the needs of device normal work, can directly use in the market
Prior art products can also specially make according to the needs for realizing designing technique index.
(2) working procedure
The working procedure of the present apparatus is as follows：
It is manufactured by design objective with installing each component, assorts dynamical system and auxiliary equipment, and debug ready.
Selection and the magnetic induction intensity for confirming two interpolar of magnet.When employing an electromagnet, the electricity of its DC power supply is adjusted
Pressure, makes magnetic field intensity reach designated value.If using permanent magnet, it must confirm that its magnetic induction intensity is met the requirements.Mask work
The effective magnetic field intensity in area generally should be more than 0.0120T (tesla), and theoretically magnetic field intensity is the bigger the better.
Start 0 fluid conveying dynamical system of ionisation chamber.Start water conveying equipment, open and adjust associated section valve, make salt

The ability of 345.6 ten thousand steres (432 ten thousand stere of processing seawater), that is, produce 12.6 billion cubic meter of fresh water (processing seawater per year
15.768 billion cubic meters), Beijing's whole city's water resource insufficiency of supply-demand of 1 year can be filled up (2016 are 8.91 billion cubic meters).
Operation cost is low.
(1) equipment cost is low.According to make model machine expense carry out initial estimate, about 2.1 ten thousand yuan of the expense of 1 model machine,
Fresh water ability 1.5L/min is produced, that is, produces fresh water 2.16m3 daily, produces fresh water 788.4m3 per year.It calculates according to this, builds 10,000 cubes of daily output
The equipment cost of metric system outlet capacity is 97,220,000 yuan, i.e. 9722 yuan/ton/day, higher than 4000~5000 yuan/ton of hyperfiltration/
Day.But once into industrialization production, equipment cost should insufficient current prototype fabrication fee calculating cost three/
One, less than the equipment cost of hyperfiltration.
(2) water producing cost is low.Calculate by the experimental data obtained with model machine, the present invention energy consumption of seawater preparing fresh
For 2.63~1.92kWh/m3, often spend 0.5 yuan of electricity by current civilian electricity price and calculate, 1.3~1.0 yuan/m3 of power consumption cost, and
Equipment consume expense is very low, and without extra charge.Therefore, water producing cost of the invention is substantially less than hyperfiltration and sudden strain of a muscle
The water producing cost of 4.0~5.0 yuan/m3 of steaming method.
(3) maintenance cost is low.Apparatus of the present invention are in operation without vulnerable part and the expendable part in low service life, without regular
Component is replaced, therefore its operation and maintenance cost is very low.
It is applied widely.The equipment occupation space of the present invention is small, and low cost, water consumption processed is small, and water scale processed is simultaneous
Preferably.Unit 1~10m3/d of water-making ability, occupied space is suitable with conventional domestic refrigerator, is suitble to the environmental conditions such as island, ship
Under small water supply water need.Meanwhile apparatus of the present invention can be formed by online combination until daily output fresh water 10,000 tons
Above production scale can provide seawater and brackish water for the city, small towns, factories and miness of big or middle water requirements and desalinate water processed.
Environmental pollution is small.In reverse osmosis hair and multistage flash vaporization desalination process, one ton of fresh water is often produced by by-product 1
~2 tons of strong brines, strong brine and retired film etc. can all cause centainly to pollute.Sea water desalination is carried out with the present invention, often produces one ton
Fresh water only generates 0.1~0.2 ton of strong brine, and without the by-products problem of environmental pollution such as retired film, water treatment compound.Cause
This, relative to hyperfiltration and multistage flash vaporization desalination technology, the present invention has apparent environmental-friendly advantage.
The above description is merely a specific embodiment, but protection scope of the present invention is not limited thereto, and appoints
What those familiar with the art in the technical scope disclosed by the present invention, can readily occur in change or replacement, all should
It is included within the scope of the present invention.Therefore, protection scope of the present invention should it is described using scope of the claims as
It is accurate.
