Description

The invention relates to hardware. About {Formulating heat and mass transfer processes and can be used in chemical, petrochemical and some other related industries when cleaning micro fogs, aerosols, and also when cleaning gases from dust in a gas-liquid system.

The purpose of the invention is to intensify the process of mass transfer by reducing longitudinal mixing.

FIG. 1 shows the apparatus, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The centrifugal apparatus includes a horizontally rotatably mounted body 1, on which double annular partitions 2 are fixed, an axis 3 with doubled disks 4, dividing the working volume into a number of sections 5, a liquid inlet 6, a gas inlet 7, an inlet 8 liquid outlet, gas outlet pipe 9, cavity 10, chamber 11, overflow holes 12, hydraulic lock 13, cavity 14, radially mounted rotating blades 15.

The device works as follows.

The liquid phase is fed into the housing 1 of the apparatus through the nozzle 6 and is directed to the first section 5 in the direction of movement. As fluid accumulates, its annular layer increases against the wall of housing 1. After the edge of the peripheral section of the double discs 4 reaches, the fluid flow enters the cavity 10 and enters into the chamber 11, from where, under the action of centrifugal forces, is ejected through the holes in the bottom of the chamber 11, into section 5 with the formation of a highly developed mass transfer surface.

This is an intensive interaction of the liquid phase with the gas supplied to the contact through the pipe 7. After passing through the volume of the section, the liquid droplets reach the surface of the annular layer of the liquid phase and merge with it. Thus, at a single contact stage, a circulation liquid circuit arises. Part of the liquid through the overflow holes 12 enters the hydraulic lock 13, from where it flows into the next section 5, where the process of contacting the phases is repeated. Having passed all the contact zones, the liquid enters the cavity 14, from where it is removed from the apparatus through the nozzle 8. After passing through the contact zones, the gas phase is fed to radially mounted rotating blades 15, where the droplets are separated, and then through pipe 9 is removed from the apparatus.
