Abstract
The utility model is an electric desalination device, which comprises a plurality of laminated electrodes and a plurality of separation sheets, wherein the laminated electrodes are arrayed in row and the electrodes are isolated by the separation sheets and work by the DC charged on the two ends of the device. The device has the advantages of simple structure, energy conservation, no second pollution and high adaptability to the working environment, and can be widely used in desalination of various water solutions.
Description
Technical field
The utility model relates to a kind of aqueous solution desalination plant, particularly a kind of electric desalination plant.
Background technology
The common technology that adopts of salinity that will remove in anhydrating has embrane method, ion exchange method, electric desalination method etc.Embrane method such as reverse osmosis etc. are by filtering principle desalination, the strictness of device front end preliminary treatment, and front-end processing and device often will add a large amount of Scale inhibitorss, acid, alkali when safeguarding, cause secondary pollution; The used exchange resin cost of ion exchange method is higher, and regeneration of resin also needs to add bronsted lowry acids and bases bronsted lowry, also can pollute; Existing electric desalination plant also is to adopt membrane technology (as Chinese patent publication number CN2561782 in essence, CN1762841 etc.), its essentially consist all comprises parts such as yin, yang ion-exchange membrane, dividing plate, electrode, under the effect of DC electric field, make the ion orientation movement, see through the yin, yang ion-exchange membrane and realize desalination.Because the existence of yin, yang ion-exchange membrane, require to have only through the water of strict pre-treatment this device of being allowed for access and handle.In addition, the decomposition of water is arranged in the electrode working process, form Faradaic current, be difficult to the problem of avoiding energy consumption high.Though these technology widespread usage, these shortcomings are difficult to overcome always, be necessary to seek in addition suitable desalination technology.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of simple in structure, non-secondary pollution, electric desalination plant that energy consumption is low are provided.
Technical solution of the present utility model is: a kind of electric desalination plant, it is characterized in that comprising multi-disc pellet electrode and multi-disc barrier sheet, pellet electrode is arranged in parallel, and is separated by barrier sheet between electrode, and the end electrode at two ends is by good electric conductor and draw wiring and be connected with direct supply.
The length of preferred electrode and the ratio of width are 3～7.
Preferably water-in and the water outlet at device is respectively equipped with the current uniform distribution device.
Ultimate principle of the present utility model is the electric charge principle that there is a natural attraction between the sexes, salinity in the water generally exists with ionic species, when saliniferous water passes through device, enter in the interelectrode slit, because applying direct current makes electrode one side positively charged, a side electronegative, and make and produce voltage between adjacent electrode, make and form electric field between adjacent electrode, under effect of electric field, negative ion moves against direction of an electric field, positive ion moves along direction of an electric field, arrives behind the electrode owing to the electric charge principle that there is a natural attraction between the sexes adheres on the electrode.The salt ion content of water outlet has just tailed off, and has also just reached the purpose of desalination.After inhaling for some time, because former electric field has been offset in the effect of the ionic reversed electric field of accumulation, at this moment just can not continue to attract the ion desalination on the electrode.At this moment, can ion be got back in the solution discharge of direct current wiring short circuit, the water short period of time washes and just can obtain fresh electrode, restarts work.
The utlity model has following characteristics: do not have any obstruction mobile element between (1) electrode, so the loss of device for mechanical energy is little.In addition, only for attracting slight ionic electrical forces, this energy is also very little for the energy consumption of desalination.Therefore energy is saved in whole device work very much.(2) place that current pass through between electrode does not have the element existence of micropores such as film, can not cause dirty blocking up, and the working range that device is adapted to is wider.(3) barrier sheet as dividing plate can make the multi-disc electrode be connected in parallel between electrode, increases total removal amount of salt ion.Can adopt tens to the hundreds of sheet according to the electrode materials of reality employing, the number that the water treatment amount is adjusted electrode in parallel.(4) non-secondary pollution needn't add additional agent during device busy, has non-secondary pollution, eco-friendly characteristics.(5) import and export are provided with the current uniform distribution device, and when the multi-disc electrode was worked simultaneously, current were evenly distributed along between each electrode, and each electrode can both be guaranteed in good working order.
Describe concrete structure of the present utility model in detail below in conjunction with drawings and Examples.
