ДЛЯ СИСТЕМ ТВЕРДОЕ ВЕЩЕСТВО-ЖИДКОСТЬFOR SYSTEMS SOLID-LIQUID

Изобретение относитс к массообменным процессам химической технологии и может быть использовано при экстракции дл систем твердое вещество-жидкость.This invention relates to mass transfer processes in chemical technology and can be used in extraction for solid-liquid systems.
Известен способ непрерывной экстракции дл систем твердое вещество-жидкость, вклю чающий противоточное контактирование твердого вещества и экстрагента в колонном аппарате пульсационного типа в режиме стесненного осаждени твердого вещества и отвод экстрагента в верхней части аппарата 1.A known method of continuous extraction for solid-liquid systems includes countercurrent contacting of a solid and an extractant in a pulsation-type column apparatus in the mode of constrained solid deposition and removal of the extractant in the upper part of the apparatus 1.
Недостатком этого способа вл етс уменьшение поверхности массообмена вследствие уплотнени твердого вещества при наложении пульсаций.The disadvantage of this method is the reduction of the mass transfer surface due to compaction of a solid substance when pulsations are superimposed.
Цель изобретени - интенсификаци процесса за счет увеличени поверхности массообмена.The purpose of the invention is to intensify the process by increasing the mass transfer surface.
Указанна цель достигаетс тем, что в известном способе режим стесненного осаждени твердого вещества чередуют с режимом свободного осаждени твердого вещества.This goal is achieved by the fact that, in a known method, the mode of constrained solid deposition alternates with the mode of free deposition of a solid substance.
На чертеже показана схема, реализующа указанный способ.The drawing shows a diagram implementing this method.
Твердое вещество непрерывно загружаетс в верхнюю часть колонны 1. Снизу противотоком непрерывно подаетс экстрагент . Экстракт собираетс в коллекторе 2 и выводитс из аппарата. Твердое вещество движетс сверху вниз и выводитс в нижней части аппарата одним из известных способов. Наложение пульсаций осуществл етс пульсатором 3 через разделительную решетку 4. Чередование режима стесненного осаждени режимом свободного осаждени твердого The solid is continuously charged to the top of column 1. Extractant is continuously fed in from the bottom of the countercurrent. The extract is collected in manifold 2 and removed from the apparatus. The solid moves from top to bottom and is removed in the lower part of the apparatus by one of the known methods. The imposition of pulsations is carried out by the pulsator 3 through the separating grid 4. The alternation of the mode of constrained deposition by the mode of free deposition of solid
10 вещества производитс периодической подачей дополнительного количества экстрагента через вентиль 5 и штуцер 6. При импульсной подаче дополнительного экстрагента выше разделительной решетки 4 образуетс зона чистого экстрагента. После прекращени 10 of the substance is produced by periodically supplying an additional amount of extractant through the valve 5 and the fitting 6. With a pulsed supply of additional extractant above the separating grid 4, a zone of pure extractant is formed. After termination
15 подачи дополнительного количества экстрагента в этой зоне происходит свободное осаждение твердого вещества, в результате чего зона с режимом 7 свободного осаждени движетс снизу вверх по ходу экстра20 гента. При достижении рассто ни от зоны с режимом свободного осаждени до решетки 4 равному Н, снова вводитс дополнительный экстрагент, и процесс повтор етс аналогичным образом.15, the supply of an additional amount of extractant in this zone leads to the free sedimentation of a solid substance, as a result of which the zone with the free precipitation regime 7 moves upwards along the extra20 route. When the distance from the zone with the free sedimentation regime to the lattice 4 is equal to H, the additional extractant is reintroduced, and the process is repeated in a similar way.
