Below in conjunction with the drawings and specific embodiments the present invention is done explanation in further detail.
Fig. 1 is the structural representation based on the high pressure static electricity type fresh-water generator of ion inversion, and Fig. 2 is the local structure synoptic diagram based on the high pressure static electricity type fresh-water generator intermediate ion inversion device of ion inversion, as shown in the figure.Based on the high pressure static electricity type fresh-water generator of ion inversion, comprise the ion inversion device 3 and the insulation ion collector 4 of high-voltage positive electrode plate 1, high voltage negative plate 2, round tube type.High-voltage positive electrode plate 1 be arranged in parallel with high voltage negative plate 2, and ion inversion device 3 rotatably is located between high-voltage positive electrode plate 1 and the high voltage negative plate 2, and the axis of ion inversion device 3 is parallel with the plate face of high-voltage positive electrode plate 1.The cross section of insulation ion collector 4 is a rectangular configuration, and is located on the axis of ion inversion device 3, and the two sides of insulation ion collector 4 are parallel with high voltage negative plate 2 with high-voltage positive electrode plate 1 respectively.One end of round tube type ion inversion device 3 is the salt solution water-in, and the other end is the fresh water water outlet, and zwitterion is collected and discharged by insulation ion collector 4.
Wherein, be laid with a plurality of blades 5 on the interior circle of ion inversion device 3 vertically, the interior circle of ion inversion device 3 is laid with a plurality of and the vertical circular arc dividing plate 6 of blade in a circumferential direction, and the quantity of blade 5 and circular arc dividing plate 6 can be determined (determining as the interior round size according to ion inversion device 3) according to practical situation.Be divided into a plurality of sunk areas by blade 5 and circular arc dividing plate 6 on the interior circle of ion inversion device 3.Blade on the interior circle of ion inversion device 3 is obliquely installed along clockwise direction.Be respectively equipped with lateral partitions 7 and wash plate 8 on the two sides of insulation ion collector 4, the two sides of insulation ion collector 4 are divided into a plurality of indents zone by lateral partitions 7 and wash plate 8.Sunk area and indent zone are used for ion storage, and anti-sealing is taken away ion when axis direction flows.
In the present embodiment, the interior circle of ion inversion device 3 and the two side of blade 5 are provided with the fin 9 perpendicular to axis, prevent that ion from being taken out of the desalination efficient that ion inversion device 3 reduces seawater with flowing of water by water.Saline flow speed in the ion inversion device 3 can not be too fast, and seawater is at ion inversion device 3 domestic demand sluggish flow, to guarantee maximum ion inversion.The water that the ion of avoiding exchanging is flow through takes the fresh water water outlet to and discharges.
3 rotations of ion inversion device, and high-voltage positive electrode plate 1 and high voltage negative plate 2 are static, salt solution is flowed into by ion inversion device 3.When high-voltage positive electrode plate 1 and high voltage negative plate 2 band high voltage electric, highfield can form between two electrodes, direction by high-voltage positive electrode plate 1 to high voltage negative plate 2.Negatively charged ion is subjected to electrical forces left all the time, and positively charged ion is subjected to electrical forces to the right all the time.To left side motion, the left side wall anion concentrations are higher in the ion inversion device 3 under the effect of electrical forces left for negatively charged ion in the ion inversion device 3 in the salt solution; And positively charged ion moves right, and the left side wall anion concentration is higher in the ion inversion device 3.When ion inversion device 3 turns clockwise, negatively charged ion can position rotate to high potential energy position along with the rotation of ion inversion device 3 by low potential owing to be subjected to the restriction of blade 5, and when blade 5 certain angles, taken out of by electrical forces, quicken and move to the right side wall of insulation ion collector 4, enrichment also is discharged from, and positively charged ion and anionic species are seemingly.This fresh-water generator can efficiently desalinize seawater, brackish water and treating part trade effluent.
