SPRAYER Russian patent published in 2002 - IPC

FIELD: fluid, liquid, semiliquid, bulk material spraying equipment. SUBSTANCE: sprayer has vortex pipe with chamber for dividing pressurized gas into cold gas flow and hot gas flow and with helical nozzle-type inlet, pipeline for supplying pressurized gas into vortex pipe, cold gas flow discharge branch pipe positioned at one end of vortex pipe, and branch pipe for intaking medium to be sprayed. Sprayer has pipeline adapted for supplying cold gas flow to medium discharge zone and connected to branch pipe for discharging cold gas flow. Mixing chamber formed as annular channel is positioned in vortex pipe end adjacent to branch pipe for intaking said medium. Opening for receiving medium spray discharge branch pipe is positioned diametrically of vortex pipe. Diameter of the latter branch pipe is smaller or equal to diameter of medium intaking branch pipe and is 0.2-0.25 the diameter of vortex pipe. Length of chamber for dividing pressurized gas into cold gas flow and hot gas flow is 4-4.2 the diameter of vortex pipe. Sprayer may be used in different processes, particularly, for cooling and greasing cut surfaces with sprayed cutting liquids, for deposition and painting of surfaces, as well as in medicine and agriculture. EFFECT: wider operational capabilities, provision for spraying of emulsions of different viscosity and fraction complexity and for regulating temperature and amounts of sprayed consistencies. 1 dwg
