Изобретение относитс к аппаратурному оформлению процессов адсорбции и может быть использовано в кимической и смежной с ней отрасл х промышленности .This invention relates to instrumentation of adsorption processes and can be used in the chemical and related industries.

Известен адсорбер, включающий корпус , по высоте которого установлены ступени взаимодействи фаз кажда из которых включает контактную камеру, сепарационную камеру с завихрител ми, приемную камеру и переточные устройства Щ .A known adsorber includes a housing, the height of which includes phase interaction stages, each of which includes a contact chamber, a separation chamber with swirlers, a receiving chamber and overflow devices Sh.

Недостатком известного адсорбера вл етс низка эффективность процесса взаимодействи фаз.A disadvantage of the known adsorber is the low efficiency of the phase interaction process.

Цель изобретени - интенсификаци процесса адсорбции путем повышени скорости газового потока и увеличени поверхности контакта фаз.The purpose of the invention is to intensify the adsorption process by increasing the gas flow rate and increasing the contact surface of the phases.

Поставленна цель достигаетс тем, что контактна камера выполнена в вице цилиндра с диаметром, равным диаметру корпуса; над которой расположен патрубок ввода твердой фазы, а сепарационна камера установлена контактной и приемной камерами и выполнена из соосно установленных цилиндров с уве- пичивающимис книзу диаметром и соединенных между собой опрокинутым усеченным конусом, а также тем, что завихритель в центре снабжен втулкой, расположенной коаксиально патрубку ввода твердой фазы и установлен на рассто нии от нижележащей контактной камеры, а лопатки завихрител в верхней части расположены параллельно оси адсорбера и в нижней части под углом 30-45 .The goal is achieved by the fact that the contact chamber is made in a vice cylinder with a diameter equal to the diameter of the housing; above which is located the inlet of the solid phase, and the separation chamber is fitted with contact and receiving chambers and is made of coaxially mounted cylinders with a diameter increasing downwards and interconnected by an overturned truncated cone, and also with the swirler in the center fitted with a bushing located coaxially the input of the solid phase is set at a distance from the underlying contact chamber, and the swirler blades in the upper part are parallel to the axis of the adsorber and in the lower part at an angle of 30-45.

Claims

The adsorber consists of a housing 1, the height of which includes stages of interaction of the phases, each of which includes a contact chamber 2, an adjacent separation chamber 3 with blades. A swirl 4, the blades of which in the upper part are parallel to the axis of the adsorber, and in the lower part at an angle 30-45. The separation chamber 3 is located between the contact chamber 2 and the receiving 5 and is made of coaxially installed: o ;,; and their cylinders b and 7 with a diameter increasing downwards, interconnected by a truncated cone 8 and removed from the bottom 9, branch pipe 10 for removal of spent sorbent. The housing 1 is provided with nozzles 11 for introducing the sorbent to the phase interaction stage and a nozzle 12 for introducing the sorbent into the upper part of the adsorber. Coaxially to the separation chamber 3, a sleeve 13 is installed in the swirler 4 for supplying the sorbent to the contact chamber 2. For transporting the sorbent from stage to stage, the adsorber is equipped with a flow-through device 14 and an injector 15 .. Each contact chamber 2 is made with diameter d equal to Enclosures 1. The upper part of the contact chamber 2 is made in the form of a truncated 10-12 ° cone with a vertex angle with a smaller base (0.8 - 0.85) d and a larger base with a diameter d. The upper end of the contact chamber is 1.5 (5) distance from the swirler. (5. A connecting pipe 11 for introducing solid phases into the second and subsequent lower stages enters the sleeve 13 with a gap, the diameter of the sleeve being (0.2 ) o1, and its lower end is separated from the upper end of the contact chamber 2 at a distance of (0.4 - 0.5) d. The separation chamber is mounted from a cylinder with a diameter and length after the blade swirl 4 equal to O, 5d, and from a truncated cone 8, extending downward at an apex angle of 10-12 and connected by a smaller base to cylinder 7, and more The base with the cylinder of the receiving chamber 5 with a diameter of (1.25-1.3) C1 and a length of (1.0-1.2) s1. The adsorber works as follows Fine adsorbent (grain size 1OO-5 μm) through pipe 11, the nozzle 12 and the sleeve-13 enters the inside of the adsorber along the axis of the apparatus above the contact chamber 2 and is picked up by a gas stream moving from top to bottom along the apparatus at high speed (10-20 m / s). Pass, the lower contact chamber 2, solid phase with gas the stream enters through the vortex 4 into the separation chamber 3 for centrifugal phase separation. The solid phase separated out from the gas stream (partially spent adsorbent) under the action of centrifugal force is directed to the receiving chamber 5 and along the bottom 9 of the npncMHoii chamber moves to the transfer device 14, where it is picked up by means of an injector 15 installed in the lower part of the overflow device 14 transporting gas and is directed to the overlying stage through the pipe 12 and the sleeve 13, where the process of phase interaction is repeated as described in the lower stage. The solid phase, moving upwards from the stage to the stage, along re-flow devices, is processed and exits through the nozzle 10 of the upper stage of the adsorber, and the gas flow, having passed all the stages, comes out cleaned (freed from the target component) from the bottom of the adsorber. Each stage operates in a direct downward phase interaction, and the apparatus as a whole - in countercurrent. Claim 1. An absorber comprising a housing, the height of which has phase interaction stages, each of which includes a contact chamber, a separator chamber with swirlers, a receiving chamber and overflow devices, and to intensify the adsorption process by increasing the gas flow rate and increasing the contact surface of the phases, the contact chamber is made in the form of a cylinder with a diameter equal to the diameter of the case, which has a solid inlet phases, and a separation chamber is installed between the contact and receiving chambers and is made of coaxially mounted centers or indices with a downward diameter and interconnected tilted truncated cone.
