REGULAR ADAPTER FOR HEAT- AND MASS-EXCHANGE APPARATUSES WITH INTERMITTENT IRRIGATION Russian patent published in 2014 - IPC B01J19/32 

FIELD: process engineering.

SUBSTANCE: invention relates to regular nozzles for heat- and mass-transfer process in gas (steam) - fluid system, e.g. rectification, absorption cleaning and drying of natural gas. Besides it can be used in chemical, oil-and-gas industries, etc. Said nozzle consists of vertical parallel sheets coated on both sides with synthetic (polymer) frieze. Length of threads makes 0.007-0.01 m. Spacing between adjacent threads on sheet makes 0.002-0.003 m. Thread diameter makes 0.001-0.002 m. Spacing between sheet surfaces makes up to 0.02-0.03 m. Note here that fluid is fed on said surface from above intermittently to produce wave thereon. Spacing between threads on sheet surface makes at least 0.002 m to rule out thread-to-thread adhesion. Alternate wave wets the threads to coat them with fluid film so that developed surface of contact between gas and fluid is created. Then, next wave comes to carry old film and to produce new film thereon.

EFFECT: developed surface of phase contact, intensive heat exchange.
