HEAT-AND-MASS EXCHANGE APPARATUS Russian patent published in 1995 - IPC

FIELD: power engineering. SUBSTANCE: water escaping from air distributor nozzles gets on perforated beaded shelf located in upper portion of housing. Jets are treated with steam fed to housing to steam supply branch pipe and flash steam escapes through respective branch pipes located above and below shelf. Nozzles are arranged at angle α to the vertical. Air distributor is shifted in width of housing relative to shelf by amount found from the following inequality: S/h < tg α, where h is height of upper edge of shelf side above plane of location of nozzles at minimum distance from shelf; S is amount of shift of water distributor in width of housing which is determined by distance between nozzles which are arranged at shortest distance from the shelf and projection of shelf side on horizontal plane of location of these nozzles. Located in housing between shelf and water distributor is vertical partition. EFFECT: enhanced reliability. 2 cl, 1 dwg
