(54) СПОСОБ ИОНООБМЕНА МЕЖДУ РАСТВОРОМ И ЗЕРНИСТЫМ ИОНИТОМ(54) METHOD OF ION EXCHANGE BETWEEN SOLUTION AND GRANULAR IONITE
II
Изобретение относитс к технике осуществлени ионообменных процессов в услови х противоточного контактировани обрабатываемьпс в вертикальной колонне раствора и зернистог ионита и может быть использовано в химико-технологической и гидрометаллургической отрасл х промышленности, а также в процессах промьшшенной водоподготовки при ум гчении воды ионообменными методами.The invention relates to a technique for carrying out ion-exchange processes under conditions of countercurrent contacting of the processes in the vertical column of the solution and granular ion exchanger and can be used in chemical-technological and hydrometallurgical sectors of the industry, as well as in industrial water treatment processes with water softening using ion-exchange methods.
Известен способ противоточного ионообмена между раствором и зернистым ИОНИТОМ, который осуществл етс путем перемещени сло твердой фазы снизу вверх, а жидкой фазы - сверху вниз l .There is a known method of countercurrent ion exchange between a solution and a granular IONITE, which is carried out by moving the solid phase layer from the bottom up, and the liquid phase from top to bottom l.
Однако при указанном способе загрузку твердой фазы приходитс вести в нижнюю часть колонны, т.е. под имеющийс в аппарате слой этой фазы, а выгрузку ее - через верхний край аппарата . Такой способ загрузки и выгрузки твердой фазы приводит к необходимости приложени пульсирующих импульсов давлени как к верхнему концу загрузочной трубы, так и под дренажом в нижней части колонны, что, помимо усложнени конструкции и обслуживани аппарата, увеличивает веро тность продольного перемешивани зерен твердой фазы и, счедовательно, снижени степени противоточности контактирующих фаз.However, with this method, the loading of the solid phase has to be carried out in the lower part of the column, i.e. under the apparatus there is a layer of this phase, and its discharge is through the upper edge of the apparatus. This method of loading and unloading solids necessitates the application of pulsating pressure pulses both to the upper end of the loading tube and under the drainage in the lower part of the column, which, in addition to complicating the design and maintenance of the apparatus, increases the likelihood of longitudinal mixing of the solids grains and, , reducing the degree of countercurrent contacting phases.
