MASS-TRANSFER HEAT EXCHANGER Russian patent published in 2003 - IPC

FIELD: direct-contact mass-transfer heat exchangers, applicable in the heat-power industry. SUBSTANCE: in the mass-transfer heat exchanger, having a steam-jet nozzle installed in the body axis with formation of a peripheral annular gap, and a liquid-jet nozzle positioned in the annular gap, the annular gap is partially overlapped by segment members uniformly distributed around the edges of the gap with formation of radial slots between the adjacent members, and at least one profiled hole is made in each segment member. The set of the holes of all members jointly with the radial slots forms the mentioned liquid-jet nozzle. EFFECT: enhanced degree of liquid dispersion due to gradual steam condensation. 2 cl, 2 dwg
