Abstract

The invention relates to chemical and industrial spheres adjacent to it, can be used in the processes of absorption and wet cooling and allows increasing the efficiency of mass transfer due to the pulsating contact of liquid droplets with gas throughout the apparatus. The dispersion of a jet of fluid flowing out of a long-range nozzle, which is provided with a nozzle that feeds the apparatus body, occurs on dispersants made in the form of strips mounted along a helical line, spaced apart from each other along the length of the shaft, each of the subsequent strips is offset from. previous at an angle equal to 360 / p, where n is the number of dispersants. When the shaft rotates, a stream of liquid directed along the axis of the apparatus body is alternately divided into dispersants, starting from first to last and then again from first. 4 il. i (l have eaten about

Description

The invention relates to chemical and adjacent industrial scaffolds and may find application in absorption and wet piercing processes.

The purpose of the invention is to increase the efficiency of mass transfer by pulsating contact of liquid droplets with gas throughout the apparatus.

Fig, 1 shows a rotary heat and mass transfer apparatus; figure 2 is a view of the shaft in the assembly with dispersants; in FIG. 3, view A in FIG. 1; FIG. 4 shows a dispersant in the form of a strip.

The apparatus consists of a housing 1 with nozzles for inlet 2 and an outlet 3 for gas, an inlet 4 for introducing a fluid with a long-range nozzle 5 and an inlet 6 for expelling a fluid. In the housing there is a shaft 7 rotating in bearings 8. Dispersers 9 in the form of strips o are successively fixed on the shaft. Dispersants are installed in series along the length of the shaft and each subsequent displaced relative to the previous one by an angle Cf equal to 30%, where n is the total number of dispersants.

The device works as follows.

Gas (g) enters through pipe 2 passes through the housing 1, where it contacts with liquid (g) and flows through pipe 3. The liquid is supplied to the device through pipe 4. Discharged through a long-range nozzle 5, which is supplied with a liquid jet in the form of a jet, parallel to the rotating shaft, runs along the body of the device. The jet of liquid then breaks into the dispersant and the liquid drops fly apart in radial directions, penetrating the gas passing through the apparatus. As the shaft rotates and the dispersants are installed in series and shifted by an angle (this is when the shaft is rotated by an angle (the liquid jet breaks up to the next dispersant and the liquid drops flying radially again penetrate the gas passing through the apparatus but equal to the distance between the strips. When the shaft rotates, the jet of fluid is dispersed alternately

but on all lanes from the first to the last and after a full turn it starts again from the first. The liquid droplets that have been contacted with the gas are deposited on the body of the apparatus, collected at the bottom and removed from the apparatus through the pipe 6.

Due to the alternate dispersion of a jet of liquid on the disperser lobes arranged in series on a rotating shaft and shifted by an angle c, pulsating contacting of drops occurs

15 liquids with gas throughout the apparatus, contributing to an increase in the efficiency of mass transfer. An increase in the shaft rotation frequency, which contributes to the intensification of the process of dispersion, does not disrupt the flow of liquid to the dispersant strips, since the liquid is supplied in the form of a jet passing through the entire apparatus, thanks to the long-range nozzle. Nozzle,

25, which supplies liquid from the housing of the apparatus, ensures a radial uniform distribution of liquid droplets across the housing of the apparatus. And the length of the dispersant bands is equal to or

30 is large from the shaft to the axis of the nozzle and prevents the jet of liquid from passing past the strips without dispersion.
