Description

The invention relates to the design of piping reactors and can be used in the chemical and radiochemical industry for the processing of toxic, radioactive and aggressive substances, for example, OLE salt dissolution.

A pulsation reactor is known, comprising a disk-shaped housing inside which is placed a reaction chamber and a pulsation reactor divided by a vertical partition into two chambers, a pulsation generator, valves for input and output of components l

The prior art reactor has disadvantages. When dissolving powders, salts that are heavier in specific gravity tend to

settle to the bottom, and the liquid (light) phase tends to the top of the reactor.

Such a separation does not give a highly efficient mixing, since the surface layers of the solid and liquid phases are in contact with the contact areas, which leads to a lengthening of the technological cycle.

Whole inventions provide an example of a description of the process of coitactivation.

For this purpose, a guide apparatus c is rigidly installed in the reaction chamber; a baffle, made in the form of two confusors, connected by smaller bases, and a slotted nozzle, communicating with pulsation chambers. The walls of the guide vane are made hollow, fittings for the input of reagents are located in the upper part of the reaction chamber at an angle to each other, and the connection of the output of the salt solution is located under the baffle plate.

In the reaction chamber, a guide apparatus 9, made in the form of an ovuh confuor, connected by smaller bases, is installed. The walls of the guide vane are made hollow to communicate with the steam lines 10 and 11. A bump stop 12 is installed above the guide vane, under which fitting 13 is placed to discharge the salt solution. The baffle with the reactor lid forms two channels 14 and 15 communicated centrally with the chamber 16 of the solid phase loading, in which the screw 17 is located with the chute 18 introduced into the reagent supply area through nozzles 19 and 2O, angled to each other. The loading chamber is communicated by the nozzle 21 with a ventilation system. The reactor is equipped with a hopper 22 and a fitting 23 for emptying.

The reactor operates as follows. Solid salt is soluble from the hopper 22 by the screw 17 through the chute 18 continuously enters the charging chamber 16. Through. fittings 19 and 20 and the reactor cross-flow liquid reagents, which together with the soluble solid salt through channels 14 and 15 enter the reaction chamber 2 of the reactor. After the reactor is filled with slurry, steam heating of the guide apparatus 9 from steam lines 1O and 11 is turned on.

At the same time, pulsating chambers 5 and 6 are received from the pulse generator, which act on the column of the liquid phase in these chambers, lower the level of the liquid phase in them, which rushes up through the confuser at high speed through the slit nozzle 7 salts. When passing through the confuser, the slurry is heated, the salt is dissolved, and part of the salt solution at fitting 13 is removed from the reactor. The rest of the salt solution, beating off the baffle 12, is brought into rotational

the motion, connected to the loaded path, goes to the bottom of the reactor and rises again through the confusor. If necessary, the reactor is emptied through a special fitting 23.

Thus, the proposed reactor allows to achieve a high intensity of mixing, shortens the technological cycle of salt dissolution.

The reactor is simple to manufacture and reliable in production, provides a high intensity of salt dissolution.
