Description

The invention relates to a technique for conducting mass transfer processes in gas-liquid systems and can be used in the chemical, petrochemical, food and related industries.

The purpose of the invention is to increase the degree of extraction of gas components by increasing the rate of absorption.

The drawing shows a centrifugal absorber, a general view.

The absorber contains a primary absorption chamber 1, to the side surface of which are attached the top 2 and bottom 3 covers and the tangential nozzle 4 of the gas supply.

Below the tangential nozzle 4 on the side wall of chamber 1 there is an annular manifold 5 connected to nozzles 6 inside chamber 1. An axial supply tube 7 to nozzles 6 is mounted on the axis of the apparatus. It is connected to the upper 2 and lower 3 caps 8. Lower the cover 3 is connected to the system of cylinders 9-11, while in the cover 3 there is a hole on the axis 3, the equi-gas through the pipelines 26 is fed to the tangential nozzles 4 and 17. Liquid droplets trapped in the gas flow in chamber 1 are carried away by gas, acquire azimuthal motion and are fixed in the cylinder system 9-11, where under the influence of centrifugal force are deposited on the cylinder walls. The separated liquid, the stack, falls on the protrusion 14 and the lower edges of the cylinders 9-11, from where it is sprayed with a gas stream. A gas twisting takes place in chamber 13, and then the gas-liquid mixture enters the second separation channel 19. The separated liquid passes into the gap between the insert 22 and the lid 20, flows down the walls of the separation chamber 21 and is removed through the nozzle 25, and the gas passes into the gap between the insert 22 and the central supply tube 7, enters the chamber 21 and is removed through the nozzle 24.
