FIELD: different branches of industry, namely heat recovery, scrubbing of exhaust gases, separation of liquid and gaseous phases, conditioning of supplied air. SUBSTANCE: heat mass exchange apparatus includes inlet and outlet gas and liquid chambers, tubes wound in the form of oval or cylindrical tubes with outer ribs arranged vertically and mounted in tube plates of swirlers with branch pipes for providing rotation motion of gases between tubes and cross partitions of tube plates necessary for forming inlet and outlet gas chambers and for mounting swirlers with branch pipes. Gases are swirled by means of swirlers in intertube space at passing through branch pipes from inlet gas chamber to outlet one. Vortex cylindrical flows are formed in above mentioned space. At mounting cylindrical tubes with cross helical outer ribbing, helical motion of gases in interrib space of tubes is organized by means of intertube streams due to action of inertia force and viscosity effort. At using apparatus with oval-wound tubes or cylindrical tubes with helical lengthwise ribs, vortex motion of gases relative to their axes occurs due to gas passing along surfaces of tubes when gases move from inlet gas chamber to outlet one through slits between partitions and tubes. Sprayed liquid is fed to rotating flows through lateral openings of swirler branch pipes. Cooling liquid is fed in tubes from inlet liquid chamber and it is discharged from said tubes to outlet liquid chamber. Intensive vortex motion of gases in intertube and in interib spaces provides efficient cooling of gases, condensation of liquid vapors, separation of liquid by action of centrifugal forces on wall surfaces of heat exchanger and draining down of liquid along inclined surfaces of ribs by action of gravitational and inertial forces to condensate trap. EFFECT: improved design of apparatus, enhanced efficiency of method. 27 cl, 4 dwg
