Изобретение относитс к технологии процесса электродиализа при переработке нриродных вод и технологических растворов при обогащении, гидрометаллургии в других смежных област х производства.The invention relates to the technology of the process of electrodialysis in the processing of natural waters and process solutions during enrichment, hydrometallurgy in other adjacent areas of production.
Известен способ удалени осадка с мембран электродиализатора с одновременной турбулизацией раствора путем диспергировани в объеме обрабатываемого раствора воздуха или другого газа. Воздух или другой газ подаетс в нижнюю часть аппарата через специальный диспергатор.There is a known method of removing sediment from electrodialysis membrane membranes with simultaneous turbulization of the solution by dispersing air or another gas in the volume of the treated solution. Air or other gas is supplied to the lower part of the apparatus through a special dispersant.
Известный способ недостаточно эффективно удал ет осадок с поверхности мембран и слабо перемешивает раствор.The known method does not efficiently remove the precipitate from the membrane surface and mixes the solution weakly.
С целью увеличени срока службы мембран по предлагаемому способу в качестве диспергированного компонента используют твердые частицы различных размеров и форм из материалов с различными удельными весам и .In order to increase the service life of the membranes of the proposed method, solid particles of various sizes and shapes from materials with different specific weights and are used as the dispersed component.
С целью увеличени срока службы мембран в качестве материалов с различными удельными весами могут быть использованы эластичные материалы, например резина, полиэтилен , пенопласт.In order to increase the service life of the membranes, elastic materials, such as rubber, polyethylene, foam, can be used as materials with different specific weights.
С целью снижени расхода электроэнергии в качестве материалов с различными удельными весами могут быть использованы ионообменные материалы.In order to reduce energy consumption, ion-exchange materials can be used as materials with different specific weights.
При электродиализе рудных пульп дл сн ти осадка могут быть использованы твердые частицы, содержапдиес в перерабатываемом продукте.In the electrodialysis of ore slurries, solids can be used to remove sediment containing in the processed product.
Па чертеже схематически представлен принцип действн предлагаемого способа.PA drawing schematically presents the principle of the proposed method.
Через камеру 1 электродиализного аппарата , образованную, например, двум ионитовыми мембранами (катпонитовой 2 и аниопитовой 3) прокачиваетс диализат, в который введены твердые частицы 4, 5 с разными удельными весами и размерами, что усиливает пх боковое смещение при соударении. При наложении посто нного электрического пол у поверхности мембран образуютс пол ризованные слои 6, 7.Through the chamber 1 electrodialysis apparatus, formed, for example, by two ionite membranes (catponitic 2 and anopitic 3), dialysate is pumped into which solid particles 4, 5 are introduced with different specific weights and sizes, which increases the lateral displacement of the collision. When a constant electric field is applied, polarized layers 6, 7 are formed at the surface of the membranes.
При наличии в диализате коллоидных и тонкодисперсных частиц, которые всегда присутствуют в природпых и технологических растворах, последние оседают в пол ризованном слое. Частицы циркулирующие с диализатом , снимают образующийс осадок. Дл увеличени эффекта турбулизации раствора, частицы имеют преимущественно неправильную форму, что обеспечивает их сложное движение .In the presence of colloidal and fine particles in dialysate, which are always present in natural and technological solutions, the latter are deposited in the polarized layer. Particles circulating with dialysate, remove the resulting precipitate. To increase the effect of turbulence in the solution, the particles have a predominantly irregular shape, which ensures their complex movement.
