Description
(5) СПОСОБ РАСТВОРЕНИЯ ТВЕРДОЙ ФАЗЫ(5) METHOD FOR SOLVING A SOLID PHASE
II
Способ относитс к технике переработки солевых руд методом растворени -кристаллизации и может быть использован, например, на галургических фабриках калийных производств дл разделени двух и более компонентов.The method relates to the technique of processing salt ores by the method of dissolution-crystallization and can be used, for example, in the halurgical factories of potash production for the separation of two or more components.
Известен способ растворени твердой фазы Е- шнековых аппаратах, где растворение ведетс в последовательно соединенных горизонтальных шнековых аппаратах путем подачи в них гор чего ненасыщенного раствора и измельченной руды йП .There is a known method for dissolving the solid phase of the E-screw apparatus, where the dissolution is carried out in successively connected horizontal screw-type apparatus by feeding them a hot, unsaturated solution and crushed IP ore.
Недостатком данного способа вл етс наличие механического перемешивани , которое, с одной стороны, не обеспечивает достаточного развити поверхности контакта фаз и больших скоростей скольжени частиц относительно раствора, а с другой приводит к большим энергозатратам и высокой металлоемкости конструкции. Вследствие этого шнековые аппараты, реализующие этот способ, обладаютThe disadvantage of this method is the presence of mechanical agitation, which, on the one hand, does not provide sufficient development of the contact surface of the phases and high sliding speeds of the particles relative to the solution, and on the other hand leads to high energy consumption and high metal intensity of the structure. As a consequence, screw machines that implement this method have
НИЗКОЙ удельной производительностью, малой степенью извлечени полезного компонента из руды, отличаютс сложностью ежемес чных предупредительных и ежегодных капитальных ремонтов как самого аппарата, так и обезвоживающих элеваторов, вход щих в конструкцию аппарата.The LOW specific productivity, low degree of extraction of the useful component from the ore are characterized by the complexity of monthly preventive and annual overhauls of both the apparatus itself and the dewatering elevators included in the apparatus design.
Известен также способ растворени твердой фазы в каскаде аппаратов There is also known a method for dissolving a solid phase in an apparatus cascade.
10 с мешалками, в батарее диффузоров, в барабанном экстракторе 21.10 with agitators, in a battery of diffusers, in a drum extractor 21.
Однако известный способ растворени в аппаратах со взвешенным, или кип щим слоем не обеспечивает требуе15 мую степень насыщени конечного раст еора и непригоден дл растворени полидисперсной твердой фазы. Решетка аппарата, над которой создаетс кип щий слой, закристаллизовываетс , However, the known method of dissolution in devices with a suspended or fluidized bed does not provide the required degree of saturation of the final plant and is unsuitable for dissolving the polydisperse solid phase. The apparatus grating, above which the fluidized bed is created, crystallizes,
20 затрудн эксплуатацию.,20 difficult operation.,
Цель изобретени - разработка .способа растворени твердой фазы, интенсифицирующего процесс раствореThe purpose of the invention is the development of a method for dissolving a solid phase, which intensifies the solution process.
