Description
[technical field]
The utility model relates to a kind of Intelligent electric dialysis control system.
[background technology]
The common processing method of electroplating wastewater mainly contains chemical precipitation method, ferrite process, ion-exchange and membrane separation process etc., and electrodialysis is a kind of difference utilizing electromotive force, ions different in solution is carried out the membrane separating process be separated by ion-exchange.Electrodialysis plant is used to concentrate, extract, except the equipment of the intermediate ion that anhydrates.Electrodialysis is used for the extraction of noble metal in desalinization, water, the effective physical-chemical reaction of one of Liquid traditional Chinese medicine component separation.Due to its composition structure and apply the difference of film, and make its range of application also different.Electrodialysis filter cartridge construction, also different by the different arrangement architecture of the composition of film, its purposes also difference to some extent.Both at home and abroad done large quantifier elimination to the concentrated metal ion of removing of electroosmose process, it doesn't matter with the kind of ion for electrodialysis effect, depends primarily on reaction condition and dialysing compartment structure.Electrodialysis filter core is minimum to be made up of three chambers, and by the quantity also difference to some extent of purposes different chamber, the most frequently used is four chambers and five cavates.Filter core unit is generally made up of amberplex dividing plate harmonizing yinyang electrode.Conventional electric dialyzator inner chamber generally presses the order separation of alkali room, salt room, sour room, sample room.Filter core dividing plate be all generally and resistance to chemical attack and non electrically conductive material composition.Dividing plate is generally divided into " net type dividing plate " " rail type dividing plate ".Net type dividing plate: block board thickness is generally at 0.8 ~ 2mm, high to membrane area utilization rate, but content forms fluid space delay and damages film.Rail type dividing plate, because solving the technical problem such as the strength of materials and leakproof, so the thickness of separator material is all between 5mm ~ 10mm, does not generally cause fluid retention.But the thickness that guide tracked dividing plate cannot reduce between dividing plate taking leakage problems between the not enough and dividing plate of mechanical processing technique precision into account, and make intermembranous apart from becoming large, makes the too high in resistance of modular unit, extra power such as cannot to reduce at the problem.
Electrodialysis control system common at present has circulating interval desalination electrodialysis system, circulating continuous desalination electrodialysis system and automatically controls frequently pole-reversing electroosmosis system (EDR).Circulating interval desalination electrodialysis system is that the semi-automation of desalination system controls, also be a kind of electrodialysis control system comparatively early, the appearance of this electrodialysis system makes this desalination reaction of electrodialysis go on the road of automatic continuous production, is also that electrodialysis starts beginning that is universal and the large-scale application epoch.In circulating desalination processes, the change with fresh water circulating slot concentration changes by the technological parameter of system.So the requirement in purposes such as commercial Application, medicine, lives often still can be can not get under these circumstances.Different electrodialysis control systems is derived on the basis of this system.Circulating continuous desalination electrodialysis system is also referred to as the desalination of component loops formula.In the finished product water of electrodialysis system outlet, some will turn back to the fresh water intake chamber of system, and fresh water concentration is reduced, to reduce series connection progression or the series connection hop count of electric dialyzator.The fresh-water flow of component loops formula desalination processes is not equal to aquifer yield, and a part of fresh water will participate in backflow.Operating process is relatively more flexible, but pipe arrangement is complicated, and power consumption is large.Due to the electrode affecting electrodialysis filter core of the factor such as voltage, electric current and film surface easily attachment one deck solid salt or plating is upper or metal, this adhesion layer directly affects the process of dialysis, its productive rate is reduced, power consumption becomes large, but because in some special electrodialytic processes (recovery of electroplating effluent slaine), metal adhering amount is excessive, people are made to be obliged to go to consider how to go to eliminate this layer of attachment, what adhesion amount was few is generally that regular film group of carrying out safeguards that just can solve dirt adheres to the impact brought, and makes film activity recovery.The appearance of the dialysis method of falling pole effectively solves this problem.Its mode of operation is that electrodialysis system changes the electric current (being completed by automation control system) of anode and cathode automatically in the certain hour cycle, and make negative electrode become anode, anode transfers negative electrode to, and dense hydroecium is become freshwater room, and freshwater room becomes dense hydroecium.By the conversion of twice, when its workflow do not become but be effectively eliminate the attachment being attached to film surface.
