(54) ПУЛЬСАЦИОИНЪ1Й ЭКСТРАКТОР(54) PULSATIOIN EXTRACTOR

ii

Изобретение относитс к аппаратам хиьмческой технологии, предназначенным дл проведени процессов экстракции из растворов.The invention relates to chemical technology apparatuses intended for carrying out extraction processes from solutions.

Известен пульсационньй экстрактор вертикальный .цилин.црический корпус которого разделен по высоте ситчатымк тарелкаьа- на отстойные секции н смесительные секции с вертикапьныш перегородка- -да, вьшолненны ет в виде концентрических цилиндр ов с ко.чьцевыма выступамл. Вращательное дт пленне жидкостных потоков в аппарате создаетс путем прохождени их ь становленные в смесительных секци х тарелки с наклонными отверсти ми, ориентйрованньц и по касательным К: концентрическим окружност м ij.The pulsation extractor is known. It has a vertical ciclinic body, which is divided by the height of the sieve tray and the settling section and the mixing section with a vertical partition wall-yes, complete in the form of concentric cylinders with a horn protrusion. Rotational plenum of liquid flows in the apparatus is created by the passage of plates with inclined holes placed in the mixing sections, oriented and tangent to K: concentric circles ij.

Вра1дательное движение потоков жидкости в этом аппарате ограничено величиной пульсации, котора в свою очередь не может быть выше спределеннЕЕс пределов. Изготовление тарелок с каклонными отверсти ми дорого н металлоемко . Неполно используетс рабочий объем кольцевых каналов вращаюЕоикис стру ми.The ad hoc movement of fluid flows in this apparatus is limited by the magnitude of the pulsation, which in turn cannot be higher than the distributed limits. The manufacture of plates with open holes is expensive and metal consuming. The working volume of the annular channels is rotated by rotatized jets.

По основному авт.ев, , известен пульсаиионный экстрактор, вертикальный цилиндрический корпус кото2According to the main author, a pulsion extractor is known, a vertical cylindrical body which

рого разделен по высоте ситчатыми тарелкаг- .и на отстойные и смесительные секции с коаксиально установленными вертньсальныг С1 цилиндрическими перегородкаг- .да, в кольцевых зазорах между которыьш в один или более р дов установлены наклонные лопасти, расположенные по окружности Б горизонтальной плоскости, создающие вращение потоков- .divided by the height of the perforated plates and into settling and mixing sections with coaxially mounted rotary C1 cylindrical partition, yes, in the annular gaps between which in one or more rows there are inclined blades located along the circumference B of the horizontal plane creating rotation of the streams -.

Недостатке этого аппарата вл етс то, что на создание вращательного движени потоков используетс только энерги пульсации, причем на создание вращени используетс лишь часть этой энергии.The disadvantage of this apparatus is that only pulsating energy is used to create the rotational motion of the streams, and only a fraction of this energy is used to create the rotation.

С целью повышени производительности аппарата, обеспечени возможности более полного использовани рабочего объема и уменьшени его металлоемкости наклонные лопасти установлены в каждом;последующем кольцевом зазоре с углом наклона, увеличивающимс от центра к периферии, а экстратор снабжен мешалками с вертикальными плоскими.лопаст ми, установленными в смесительных секци х.In order to increase the productivity of the apparatus, enable fuller utilization of the working volume and decrease its metal consumption, inclined blades are installed in each; a subsequent annular gap with a tilt angle increasing from the center to the periphery, and the extractor is equipped with agitators with vertical flat blades installed in mixing sections x.

Claims

Fig, 1 shows the proposed extractor, section; in fig. 2 - vertical partition with blades. The extractor has a housing 1 with alternating mixing 2 and settling 3 sections. Coaxially mounted to the housing shaft 4 having a drive. The mixing sections are limited to two plates 5. In the mixing sections, agitators 6 with flat vertical blades are fixed on the shaft. Cylindrical coaxially arranged vertical partitions 7 are installed on the plates, forming annular gaps in the mixing sections. In these gaps, guiding inclined blades 8 are installed, the angle of inclination of the blades in each subsequent annular gap increases from the center to the periphery of the apparatus. For the supply and removal of liquid phases there are nozzles 9-12. In order to provide countercurrent and intensify the process of mass exchange, the contents of the apparatus from a separate pulsator is reported to be reciprocating. The pulsator is connected to nozzle 13. The extractor works as follows. In Ps1TrubO1 9, the phases are fed out and then it is discharged through the nozzle 1. The nozzle 11 is supplied with a light phase, discharged through the nozzle 12. In the pulsation extractor, two immiscible liquids move countercurrently, one of which is dispersed. At the same time, in the mixing sections 2, the liquid flows receive rotational motion of the agitators 6, different spinning speeds in the center and at the periphery of the apparatus in the annular gaps are equalized due to the different inclination angle of the guide blades 8. In the settling sections 3, the dispersed phase particles redistribute along the section extractor. Claims of the invention Pulsation extractor according to ed. 586918, differing in the fact that / in order to increase the productivity of the apparatus, to enable fuller utilization of the working volume and decrease its capacity, the blades are installed in each subsequent annular gap with an angle of inclination increasing from the center to the periphery, and the extractor is equipped with agitators, with vertical flat blades mounted in mixing sections.
