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

FIELD: chemical industry, mainly for chemical interaction of liquid and gas and heat-and-mass transfer processes, absorption and gas purification. SUBSTANCE: heat-and-mass transfer apparatus has vertical housing divided into sections in height and shaft on which liquid distributor and contact devices are mounted assembled of horizontal screened disks grouped in stacks: several disks in each section. Each section is made in form of truncated cones whose lesser bases are directed downward. By changing the conditions of feeding the liquid or the rotational speed of disks, thickness of film of the liquid and structure of its flow may be changed. In handling the low-pressure gases and performing the chemical reactions and absorption processes, continuous films are formed over the entire surface of revolving screened disks, thus excluding flow of gases past liquid barriers. EFFECT: enhanced efficiency. 2 dwg
