METHOD OF PERFORMING GAS-AND-LIQUID MULTI-PHASE REACTIONS AND VORTEX CENTRIFUGAL BUBBLING REACTOR FOR REALIZATION OF THIS METHOD Russian patent published in 2005 - IPC

FIELD: chemical engineering; methods of performing and intensification of gas-and-liquid multi-phase chemical reactions; chemical, microbiological and allied industries.

SUBSTANCE: proposed vortex centrifugal bubbling reactor includes vortex chamber with guide apparatus and end covers; proposed method includes injection of gas through surface of end cover provided with gas escape hole in the vicinity of inner boundary of vortex gas-and-liquid layer; mass flow rate of this gas is regulated within 20% of total flow rate through vortex chamber or/and gas-and-liquid layer is forced back from surface of one or both end covers by injecting gas through permeable part of their surfaces and/or twisted flow of gas is additionally introduced into near-axis zone of gas-and-liquid layer at control of gas flow rate and position of gas source in height; direction of rotation of additional gas coincides with direction of rotation of vortex flow of gas-and-liquid layer. Vortex centrifugal bubbling reactor is provided with vortex chamber with guide apparatus and end covers; surface of end covers is profiled in area of holding vortex flow of gas-and-liquid layer, provided with following relationship is observed:

where H is height of vortex chamber equal to distance between end covers at radius R₀, R₀ is radius of vortex chamber at boundary with guide apparatus or maximum radius; n=1.5±0.4 or/and end covers are permeable for gas either partially or fully for delivery of gas through them at adjustable flow rate or/and branch pipe with tangential guide apparatus is fitted along axis of vortex chamber for additional delivery of gas and adjustment of its flow rate in such way that direction of rotation of additional gas coincides with direction of rotation of vortex gas-and-liquid layer in vortex chamber or/and corona-forming electrodes are mounted in near-axis zone of vortex chamber which are connected to high-voltage source and/or to end cover of vortex chamber.

EFFECT: enhanced intensity of interaction of gas and liquid; possibility of performing control of efflux of liquid from vortex chamber.
