KOCHETOV'S NOZZLE FOR SYSTEMS OF WATER EVAPORATION COOLING SYSTEMS Russian patent published in 2010 - IPC B05B1/00 

FIELD: mechanics.

SUBSTANCE: invention relates to nozzles, in particular for cooling towers and systems of air conditioning, and may be used in thermal power plants to cool return water and in systems of artificial microclimate. Technical result is achieved by the fact that in nozzle for systems of water evaporation cooling body is arranged as hollow and axisymmetric. Axis of body is perpendicular to axis of header pipe hole. Body is shaped as body of revolution formed by curve of the second order, in the form of truncated ellipsoid or paraboloid of rotation. At the side of throughput hole of header pipe in nozzle there is a straightening element installed, being arranged in the form of ring, having central bushing. At least three radially arranged blades connected to nozzle body are rigidly fixed to bushing. Body is arranged with two ledges arranged oppositely and perpendicularly to axis of nozzle. Nozzle is fixed on header by means of ledges via yokes with locks. In lower part of nozzle body there is a conical throttling hole connected to mixing chamber, which is arranged between throttling hole and straightening element. On inner surface of mixing chamber there are helical grooves, which are formed by turning treatment by guide plate or formed by casting method.

EFFECT: higher efficiency of operation.
