DEVICE FOR DISPERSING DROPLETS OR BUBBLES IN LIQUID IN MICRO-CHANNELS AND METHOD FOR OPERATION THEREOF Russian patent published in 2017 - IPC B01J8/04 

FIELD: physics.

SUBSTANCE: invention relates to devices for dispersing droplets or bubbles in micro-channels and can be used in processes of dispersing gas in a liquid, one liquid in the other (emulsion), with accompanying reaction, heat- and mass-exchange processes, for example, for conducting heat-exchange, extraction, gas-liquid reactions, reactions in liquid-liquid systems, absorption in chemical, petrochemical, pharmaceutical, food and other industries. In the device for dispersing droplets or bubbles in a liquid in micro-channels, the housing consists of a chamber and a micro-channel. The chamber is located at the point of feeding the medium into the device and has the shape of an oblong ellipsoid, which gradually narrows from the middle section to the ends of the chamber. One of the ends of the chamber is connected to a pipe for feeding a continuous liquid medium. The other end of the chamber is connected to the micro-channel, in which the main process occurs. The pipe for feeding the dispersion liquid or gaseous medium is the form of an extended thin-wall pipe, installed coaxially relative to the pipe for feeding the continuous liquid medium and the chamber. According to the method of using the device, the end of the extended thin-wall pipe is installed between the plane of maximum cross-section of the chamber and the plane of connection of the micro-channel to the chamber.

EFFECT: group of inventions, which enables to maintain stable hydrodynamic conditions of the process, achieving the given mixing intensity, which in turn provides high coefficients of heat and mass transfer, wider range of flow rate of the continuous and dispersion phases, which improves versatility of the device and allows use thereof for processes with different parameters.
