Abstract

The invention allows to intensify heat and mass transfer processes that occur during direct contact of gas with liquid at high flow rates of liquid in the bubble layer in the field of centrifugal forces. The apparatus contains a vortex chamber consisting of the upper 8 and lower 9 end walls between the guide element 7 with tangential slots. In the lower end wall of the chamber there is a collector (K) 10 with openings directed to the inside / az

The device works in the following manner.

As a consequence, the rotation speed of the layer also increases.

The gas-liquid mixture, running along with the gas, rises along the profiled wall 8 to the exhaust pipe of the chamber, the main part of the spent waste is thrown by centrifugal forces to the walls of the body and through pipe 4 is removed from the apparatus. Small drops contained.

Small splashes of solution, The gap between the hull I and separatoron 12, coagulate, flow down the glass rings 13, the cone separator closes and flows into the separation volume, and the gas is discharged from the ajt-parata through the pipe 6 ,.

The proposed apparatus has advantages over the prototype, since it has all the conditions for working with gas and liquid contact at high fluid flow rates, which are often necessary for various technological purposes to remove the heat of reaction, provide an absorbent capacity and etc

Due to the fact that the flow of fluid into the working volume of the vortex chamber of the apparatus is carried out by a collector located in the lower thorium wall of the chamber, through openings that are uniform in circumference and directed tangentially in the direction of rotation of the gas flow, opposite, the rotation of the liquid film formed with this liquid inlet reduces the friction of the bubbling layer on the lower end wall of the chamber, and secondly, from the bottom of the vortex chamber,

wounds all the elements, friction; 1l slo.

As a result, with the same gas flow rates, and therefore the same speed of injection, the speed of rotation of the layer, determined by the intensity of the processes of heat and mass transfer, will be significant,

Experimental results suggest that when working with large liquid flow rates5 when its mass is f5-2 times the mass of a mass, the liquid supply through the bottom end glass significantly intensifies the processes of heat and mass transfer and makes it possible to do without additional media. twist (kryshchatok, plates).
