(54) ЭКСТРАКЦИОННЫЙ АППАРАТ КОЛОННОГО ТИПА(54) COLUMN TYPE EXTRACTION DEVICE

1one

Изобретение относитс к аппаратам дл экстракции в системе жидкость-жидкость и может найти применение дл экстракции аб; солютного эфирного масла из концентрированной мисцеллы.The invention relates to liquid-liquid extraction apparatus and can be used for the extraction of ab; salt essential oil from concentrated miscella.

Известен экстракционный аппарат колонного типа, состо щий из корпуса, по высоте которого расположены воронкообразные тарелки, образующие ступени экстракции , с диспергирующим устройством в виде попарно направленных навстречу друг другу сопел, а между периметром тарелки и стенкой корпуса имеетс кольцева щель с перегородками в виде направл ющих лопаток 1 .A column-type extraction apparatus is known. blades 1.

Недостатком этого аппарата вл етс плохое диспергирование фаз за счет быстрой коалесценции капель в большом пространстве , где наход тс сопла, а также продольное перемещивание. Кроме того, отсутствие переточных устройств требует дополнительного усилени напора струи фаз, что вызывает значительные конструктивные усложнени в виде кольцевой щели с направл ющими лопатками, и создает нежелательную гидродинамическую обстановку в аппарате. Все это отрицательно вли ет на массообмен и производительность аппарата .The disadvantage of this apparatus is the poor dispersion of the phases due to the rapid coalescence of the droplets in the large space where the nozzles are located, as well as the longitudinal movement. In addition, the absence of overflow devices requires additional strengthening of the head of the jet of phases, which causes significant structural complications in the form of an annular gap with guide vanes, and creates undesirable hydrodynamic conditions in the apparatus. All of this has a negative effect on mass transfer and machine performance.

Цель изобретени - интенсификаци процесса за счет повыщени степени массообмена и увеличени производительности.The purpose of the invention is to intensify the process by increasing the degree of mass transfer and increasing productivity.

Поставленна цель достигаетс тем, что аппарат снабжен расположенной между выХ10ДНЫМИ торцами сопел диффузионной камерой с отверсти ми, соедин ющими ее с соплами, и цилиндром с отверсти ми, соедин ющими его с диффузионной камерой, внутри которого расположены сопла.The goal is achieved by the fact that the apparatus is provided with a diffusion chamber located between the outlet ends of the nozzles with openings connecting it to the nozzles and a cylinder with openings connecting it to the diffusion chamber inside which the nozzles are located.

Claims

The extraction apparatus consists of a body in the form of a column 1, the height of which contains the plates 2, which form the stu15 extraction foams. On each plate 2, nozzles 3 are installed in pairs directed toward each other. A pair of nozzles 3 is equipped with an insulating diffusion chamber 4, formed by a cylinder 5 tightly adjacent to the surface of the nozzles 3. The plate 2 for settling and phase transfer is equipped with phase transfer devices made in the form of hollow caps 7 with openings. Each pair of plates 2 separates the layer of nozzle 8 (Raschig rings, etc.). The extraction apparatus works in the following manner. A light phase is fed to the bottom of column 1, and a heavy phase is fed from above towards it. The phases enter the nozzles 3 directed towards each other and are dispersed at the exit from them due to the energy of the jet and collisions of drops with each other and with the walls of the diffusion chamber 4. As a result, an intensive mass exchange and extraction of the target component occurs. Through the apertures 6 of the phase from the diffusion chamber 4, they exit into the space between the plates 2 and are directed to the caps 7. Separated and separated, the phases through the openings in the caps 7 fall onto the layer of nozzle 8, where, depending on the hydrodynamic mode, type and material nozzles, additional dispersion or coalescence of droplets occurs. Pass the layer of the nozzle 8, the phases come to the next, second stage of extraction. Pass through an intensive mass transfer zone (a system of dispersing nozzles), the phases are output from the apparatus, while the light phase is drawn from the top, and the yellow phase is from the bottom. Thus, in the proposed apparatus, there is an intensive mass exchange with high productivity, the absence of the phenomenon of longitudinal mixing, good organization and redistribution of flows. The proposed apparatus with the same number of extraction steps provides a more complete extraction of the target component and increases the efficiency of the step. Claim I. Extraction apparatus of the column type, including a housing with plates that divide it in height into stages with dispersing devices in the form of nozzles facing each other, characterized in that, in order to intensify the process by increasing the mass exchange wall and increasing productivity, it provided with a diffusion chamber located between the outlet ends of the nozzles with openings connecting it to the nozzles, and a cylinder with openings connecting it to the diffusion chamber, inside which nozzles are located.

2. The apparatus according to claim 1, characterized in that it is provided with devices for the flow of phases, arranged on plates on both sides of the nozzles and made in the form of hollow caps with holes.

3. The apparatus according to claim 1, characterized in that it is provided with a nozzle located between the plates of the steps. Sources of information taken into account during the examination 1. Patent of Germany No. 1263696, p. On 01 D 11/04, 1964 (prototype).
