GAS-LIQUID REACTOR (VARIANTS) Russian patent published in 2012 - IPC B01J10/00 B01F3/04 

FIELD: chemical hardware.

SUBSTANCE: group of inventions refers to hardware of chemical processes running in the gas-liquid medium, namely to gas-liquid reactors with ascendant one-way flow of phases. It can be, particularly, used for industrial production of carbamide. Gas-liquid reactor consists of vertical body with reagent inlet and reaction product outlet nozzles and mixer situated in the lower part of the body. Mixer is connected to the inlet reagent nozzles and has axial outlet upward nozzle with diffuser. Both variants of reactor have cylinder shell concentric to its body comprising mixer. Its diameter is within (0.6-0.9)D where D is the internal diameter of the body. In the first variant the mixer includes annular tube an at least one swirlchamber with tangent inlet nozzle connected to the inlet nozzle of first reagent. Annular tube is inserted into the cylinder body of swirlchamber and connected to the inlet nozzle of second reagent. In the second variant the mixer includes at least two series-connected coaxial swirlchambers which have tangent inlet nozzle connected to the reagent inlet nozzles and axial upward outlet nozzles.

EFFECT: increase of interacting phases dispersion intensivty and homonenious distribution of reagents in the two-phase flow.
