(54) MIXED DRAIN EXTRACTOR.

. ;;:; ,,,.

 The invention of chemical equipment, in particular, mixing and settling extractors for carrying out extraction processes, is an improvement of the known device according to the authors. St. No. 239219.

A mixing-settling extractor is known, consisting of a mixing and settling chamber, a turbine agitator and a hollow shaft located in the lower part of the mixing chamber fi.

The disadvantage of this design is that the location of the impeller in the lower

parts of the mixing chamber do not allow the extractor to operate at lower circumferential speeds, since in this case a large number of revolutions of the mixer will be required to increase productivity, which will negatively affect emulsification / phases.

The closest to the technical essence of the present invention is e-. a mixing and settling extractor consisting of a settling chamber and separated from it by two successively installed vertical partitions of the mixing chamber with prechambers and a turbine agitator; The turbine agitator is mounted on the hollow shaft and placed in the mixing chamber at the interface level. The hollow shaft extends along the height of the splash chamber, and communicates with the prechambers for light and hard phases. Vertical partition, first along the phase movement from the mixing chamber to the settling basin, supplied with overflow pipes with locking devices 2J. :

Significant disadvantages of this extractor are:

1. A little intensification of mass transfer phases, since the vertical partitions in the sweat chamber 5 do not contribute to a sufficiently complete turbulization of the mass transfer process, as a result of which the unreacted light phase passes into the sludge chamber. This is especially pronounced when the extractor operates in the “soft” mode.

20 mixing.

2. The twisting of the emulsion flow around the rotating hollow shaft creates a ballast volume area with a constant concentration of the shaft shaft, which prevents 5 ;; the efficiency of the extraction stage is greater.

The purpose of this invention is to intensify the mass transfer process and increase the productivity of the extractor.

To achieve this goal, the extractor is equipped with baffles located in the mixing chamber, contributing to the creation of an emulsion directed into the working volume of the vortex flows. A hollow shaft of a turbine agitator is removed by inclined blades, which are the spot destruction of the swirling flow of the emulsion around the pro- gram.

The inclined blades of a turbine agitator are located at an acute angle to each other ,,,.,.: .. --- ..- ,,,. ..-.:.-.- .. ...... ,, l

The mixing and settling ex- grator consists of a mixing chamber 1 with a precamera, 2 liters of a heavy phase, a precamera 3 for the light phase and a chamber with a restraint 4. ,, ;;;

In the mixing chamber, horizontal partitions are located — the lower partition 5 and the upper 6 separating the mixing chamber 1 from the prechambers 2. yy - --- - yy - -; -; :: - In the central part of the mixing chamber 1 on the shaft 7 p with windows 8, intended for the introduction of the light phase, mounted on a turbine mixer 9 and turbine inclined blades 10, located at an acute angle.

The rabo 5 mixing sludge extractor melts as follows .:

The light phase enters the prechamber &, and r into the prechamber 2. From prechamber 2,

Both phases through the hollow shaft 7 enter the cavity of the turbine agitator 9. After the working fluids are displaced, mainly by the main pertch of the inclined blades 10 and the baffles, both phases are already in the form of an emulsion through the windows 13 and 14 and the valves 15, 16 enter settling chamber

5 After the delamination process, the clarified light phase, through the window 21, exits the extractor or is directed to the next stage of extraction.

The clarified hard phase through the water seal 18 and the nozzle 20 exits the extractor or enters the next extraction step,
