SU146287A1 - Centrifugal Reactor Separator - Google Patents

Description

This invention relates to Separator reactors.

The known apparatuses used in hydrometallurgical processes operate at speeds of movement of the solution and solid matter of 1 O-15 m / s. In connection with this, the reaction proceeds slowly, and the process requires a very large amount of leaching and carburizing equipment.

The proposed centrifugal reactor-separator for carrying out the process of dissolution or chemical interaction between the granular material, gaseous substances and liquid differs from the known ones in that its rotor is made with a hollow shaft, on which the impeller turbine and separation discs are mounted, with gaps between them The disc diameter is smaller than the impeller diameter, and the gaps communicate with the shaft cavity through the openings in its walls to discharge the processed liquid and reaction products. Thanks to this reactor design, the continuity of the reaction process is ensured.

The drawing shows the proposed centrifugal reactor-separator section.

It consists of a housing 1 in which an impeller 3 and a disk separator 4 rotate on the hollow shaft 2. The drive is driven from a 14 kW electric motor (not shown) through a text-cutting transmission. The body of the impeller, drives disks are made of acid-resistant steel.

Pulp or a solution containing a solid substance, which must enter into the reaction (zinc candle, oxide or zinc dust), through the nozzle enters the hermetic case 1, in which the impeller 3 develops a pressure of up to 15 atm. Under the influence of centrifugal force, all solid particles are thrown onto the maximum perimeter of the body, arranged in a ring around the separating device 4, rotating by friction following the disks of this device.

Due to the fact that the diameter of the disks of the separating device is slightly smaller than the diameter of the impeller, the solution and microscopic solid particles penetrate into the gaps between the disks and through the holes 5 enter the hollow part of the shaft, at PS psa1 of which are removed from the cenapaTo reactor ia to the next stage of the process. The different diameters of the centrifugal impeller and the separator discs allow the degree of separation to be automatically controlled and the system provides the necessary residue in the reactor for optimal reaction conditions. When the pulp is forced through the gaps between the disks, under the influence of centrifugal force, there is an additional separation and activation of solid particles, from the surface of which rapidly rotating disks break the formed substances. The solid particles are discarded to the maximum perimeter: where they react at a high opposite speed with the substance of the solution. The reactor separator can be used for oxidation, chlorination, etc. by feeding into the housing through the union
