HORIZONTAL NOZZLE HEAT AND MASS EXCHANGER Russian patent published in 2021 - IPC B01D3/30 

FIELD: chemical engineering.

SUBSTANCE: invention relates to processes and devices for chemical engineering and can be used in power, oil and gas, nuclear, chemical, food, pharmacological and other industries for rectification, absorption, vacuum evaporation, desorption, concentration, etc. processes in the gas-liquid system, as well as in absorption systems aimed at preventing the release of hydrocarbon vapors into the atmosphere at oil refineries, for purifying steam from radioactive aerosols during the concentration of liquid radioactive waste by evaporation, etc. A horizontal packed heat and mass transfer apparatus containing a cylindrical body partially filled with liquid with bottoms and at least one split flange, nozzles for a gas (vapor) medium in the upper part of the apparatus and a liquid medium in the lower part. The apparatus has a set of sections of annular packing structures, partially immersed in a liquid and located adjacent along the axis of the shaft, separated by external annular and internal annular or disk partitions, which form a zigzag radial-axial and series-parallel channel for the passage of gas or steam through adjacent annular packing structures.

EFFECT: invention allows simplifying the design of the apparatus, providing a higher manufacturability, achieving a higher efficiency of heat and mass transfer processes, increasing the productivity of the apparatus, using the kinetic energy of the gas or steam entering the apparatus as a driving force to drive the rotation of the packing structures.
