(54) ЦЕНТРОБЕЖНЫЙ АДСОРБЕР(54) CENTRIFUGAL ADSORBER

Изобретение относитс к массообменнвлм аппаратам и может использоватьс в эфиромасличном производстве дл выделени эфирных масел из дистилл ционных вод адсорбционным способом.The invention relates to mass transfer apparatus and can be used in the essential oil industry for the separation of essential oils from distillation water by the adsorption method.

Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс аппарат, содержащий цилиндрический корпус, в котором установлен вал с закрепленными на нем кассетами, кажда из которых выполнена в видедвух коаксиально установленных перфорированных цилиндров, между которыми размещен слой адсорбента и перераспре- t. делитель жидкости.The closest to the invention in its technical essence and the achieved result is an apparatus comprising a cylindrical body in which a shaft is installed with cassettes fixed on it, each of which is made of two coaxially mounted perforated cylinders, between which an adsorbent layer is placed and redistributed. liquid divider.

Известный аппарат не обеспечивает посто нной скорости протекани жидкости через слой адсорбента,, так как при повышенных оборотах кассеты, за счет увеличени центробежной силы, скорость протекани жидкости через слой адсорбента также увеличиваетс . ,В результате чего наблюдаетс неполное извлечение эфирных масел из дистилл ционных вод. При пониженных оборотах кассеты дистил ционна вода протекает преимущественно через слой адсорбента в нижней частиThe prior art apparatus does not provide a constant flow rate of fluid through the layer of adsorbent, since at elevated speeds of the cassette, due to an increase in centrifugal force, the flow rate of fluid through the layer of adsorbent also increases. As a result, incomplete extraction of essential oils from distillation water is observed. At lower cassette turnovers, distilled water flows predominantly through the layer of adsorbent in the lower part.

кассеты. В этом случае адсорбент контактирует с жидкостью не по всей высоте кассеты.cassette. In this case, the adsorbent is in contact with the liquid is not the entire height of the cassette.

Целью изобретени вл етс улучшение гидродинамических условий процесса путем стабилизации скорости протекани жидкости через слой адсорбента независимо от скорости вращени кассеты.The aim of the invention is to improve the hydrodynamic conditions of the process by stabilizing the rate of flow of fluid through the layer of adsorbent, regardless of the speed of rotation of the cassette.

Эта цель достигаетс тем, что в центробежном адсорбере, содержащем цилиндрический корпус, в котором установлен вал с закрепленными на нем кассетами, .кажда из которых выполнена в виде двух коаксиально установленных перфорированных цилиндров , между которыми размещен слой адсорбента и перераспределитель жидкости, вал выполнен полым и перфорированным в зоне расположени кассет , кажда из которых снабжена соединенной с ней коаксиально установленной кольцевой камерой, сообщающейс перераспределителем жидкости с валом.This goal is achieved by the fact that in a centrifugal adsorber containing a cylindrical body in which a shaft is installed with cassettes attached to it, each made of two coaxially mounted perforated cylinders, between which an adsorbent layer and a liquid distributor are placed, the shaft is hollow and perforated in the area where the cassettes are located, each of which is provided with a coaxially mounted annular chamber connected to it, which is connected with a shaft by a redistributor of fluid.

Claims

As a result, the hydrodynamic conditions of the adsorption and desorption process are improved and stabilized, since a constant flow rate of liquid through the adsorbent layer is provided, depending on the capacity of the apparatus. FIG. 1 shows an apparatus, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - section BB on. FIG. one; in fig. 4 — node I in FIG. 1 The adsorber consists of a cylindrical body 1 in which a hollow perforated shaft 2 is placed securing. ..- i - r jt 4 iJt4UJCM.i DdJi t. lollen on it cassette 3, made in the form of two perforated coaxially arranged cylinders 4, between which the adsorbent is placed 57. Cassette 3 is equipped with an annular chamber b connected to the downstream section of the hollow shaft using a redistributive fluid, which is a diametrically positioned on The shaft 2, the pipe 1 connecting the chamber b through the open ends of the pipe and the pipe 8 with the lower section of the hollow shaft 2 can be attached to the barrel similar to a cassette with a camera. The apparatus works as follows: The treated fluid, for example distilled water, from which essential oil must be extracted, through the upper part of the hollow perforated shaft 2 enters the rotating cassette 3. Due to centrifugal force, the fluid flows through the layer of adsorbent-5 and collects in chamber 6 from where on the tubes 7 and 8 re. -. flows into the downstream section of the shaft 2, then into the downstream cassette, or out of the apparatus. Similarly, carry out the process of desorption of the essential oil from the saturated adsorbent using a solvent. The adsorption – desorption processes are intensified in the field of centrifugal forces, and the execution of a shaft, a cassette and a peg of a liquid distributor in the proposed form provides an improvement in the hydrodynamic conditions of contact between the liquid and solid phases by setting the required constant flow velocity of the liquid regardless of the number of revolutions of the cassette . Claims of Invention A centrifugal adsorber comprising a cylindrical body in which a shaft is installed with cassettes fixed thereto, each of which is made in the form of two coaxially mounted perforated cylinders, between which an adsorbent layer and a liquid redistributor are placed, characterized in that in order to improve the hydrodynamic conditions process by stabilizing the rate of flow of liquid through the layer of adsorbent, regardless of the speed of rotation of the cassette, the shaft is made hollow and perforated in the zone of the position of the cassettes, each of which is provided with a connected. with it and a coaxially mounted annular chamber communicating with the fluid distributor and the shaft.
