VORTEX TYPE HEAT GENERATOR OF HYDRAULIC SYSTEM Russian patent published in 2006 - IPC F24J3/00 

FIELD: heat power engineering, namely heating apparatuses operating due to heating liquid in result of cavitation and vortex processes occurred in it, possibly used for heating chemical reactors and intensifying their operation.

SUBSTANCE: vortex heat generator of hydraulic system includes drive pump type source of liquid flow whose outlet is communicated with nozzle arranged in peripheral range of larger diameter of cone like nozzle device. At least one outlet duct of nozzle device is communicated through outer hydraulic system with suction duct of pump type source of liquid flow. The last is in the form of impeller such as impeller of centrifugal pump with covering discs and it is mounted in nozzle device in zone of its maximum diameter. Outlet cross section of said impeller is closed by means of rim for forming peripheral annular high-pressure chamber inside impeller. Nozzle is arranged at least in one end wall of annular chamber of impeller in its circumference and it is in the form of flow-through throttling ducts dispersed along peripheral diameter of annular chamber. In order to enhance suction capability of impeller at operation with double-phase liquid, throttling spraying passages are provided for communicating inner cavity of nozzle device with inlet zone of blade system of impeller. In order to improve power production efficiency, additional protrusions and acoustic resonators are provided on periphery of impeller along its diameter less than diameter of nozzle arrangement.

EFFECT: improved power characteristics, mass and size parameters of heat generator, possibility of wide usage of impellers, members and units of standard centrifugal pumps.
