Description

one

Known by the author. swith No. 320139 reactor for carrying out the process with a granular catalyst, consisting of a jacketed body for heat transfer fluid, divided by sectioning baffles with apertures, a mixing device enclosed in a cylindrical mesh permeable to the hull as per the shell.

The purpose of the invention is to automatically maintain in each section of the reactor a predetermined concentration of a solid granular catalyst.

This goal is achieved by the fact that the agitators of the mixing device are provided with end projections against which rings are mounted on the cylindrical grid separating the stirrer from the reaction volume.

The drawing shows the reactor.

The reactor includes a housing 1 with a jacket for heat carrier 2, a cylindrical grid 3, rings 4, agitators 5 with end protrusions 6, fixed on shaft 7, partitioning partitions 8 with overflow holes, and

nozzles 9 and 10 for withdrawing and introducing a thermostatic agent, as well as nozzle 11 for introducing a granulated catalyst and nozzle 12 for introducing the charge.

The reaction products are discharged from the apparatus through the nozzle 13.

The reactor operates as follows.

Before each section of the reactor, a certain amount of granular catalyst is loaded, the maintenance of which in each section is ensured by the hydrodynamic mode of operation of the apparatus. The reactor is filled with the charge and the shaft of the apparatus 7 is rotated. After the start of the reaction, the apparatus is continuously fed through the nozzle 12 and the granular catalyst through the nozzle 11. The flow of the charge from the section to the section of the apparatus passes through the aperture into the partitions 8.

Continuously circulating along the circumference of the perforated mesh and around each of the rings 4, the charge in each section is continuously in contact with the granulated catalyst mixes and maintains the catalyst in 35 volumes limited by mesh 3, housing 1 and rings 4. When the maximum concentration of catalyst granules in the section is reached, the holes in the partitions 8 move from 6b TOifflbix rpairyn to the next section. Formation of polymer leaves the reactor through nozzle 13. A feature of the proposed coistraction of the reactor is to maintain {the bulk of the granular catalyst in the volume between the rings 4, the housing 1 and the cylindrical grid 8 by circulating the b1x currents of the charge resulting from the rotation of the agitators 5 s wedge protrusions 6. Depending on the height of the protrusions 6 of the agitators 5, rings 4 and their distances from the partitioning partitions 8, the concentration of the granules maintained in the volume of the section may vary. Claims of the Invention Reactor for conducting processes with granular catalyst according to the authors. swith No. 320139, characterized in that, in order to automatically maintain in each section of the reactor a predetermined concentration of a solid granulated catalyst, the agitators of the agitators are equipped with end lugs against which rings are placed on the cylindrical mesh of the agitator from the reaction volume.
