METHOD AND DEVICE FOR EJECTION AND HEAT EXCHANGE Russian patent published in 2003 - IPC

FIELD: heating and hot-water supply systems; jet facilities. SUBSTANCE: invention is designed for transfer of liquid by ejection in water supply system. According to invention, active medium (steam) is delivered in two independent flows which are swirled in opposite directions. Parameters of flows, namely, their pressure, temperature, flow rate, are regulated independently, and steam- water mixture is directed into device diffuser in two swirled flows, central one directed along axis of diffuser and peripheral one adjoining diffuser walls. In device implementing said method main flow feed branch pipe is arranged tangentially relative to ring chamber for swirling peripheral flow, and nozzle in chamber is made as ring slot formed by walls of outer confuser and housing. Delivery of auxiliary steam flow in center is provided by independent ring chamber, and swirling is provided by inclined holes in perforated ring partition installed inside housing on handled medium (water) central supply pipe. Second nozzle in form of ring slot is formed by walls of inner confuser and central pipe. EFFECT: increased heat exchange owing to intensification of mixing of media and control of capacity. 3 cl, 6 dwg
