SPRAYING METHOD AND DEVICE Russian patent published in 2009 - IPC B05B7/02 

FIELD: mechanics.

SUBSTANCE: proposed device comprises liquid vessel (100), spraying head (160), channel (120) to feed liquid into spraying zone and spraying zone outlet communicating with the said liquid vessel just above the liquid level. The aforesaid liquid vessel has outlet (195) to let sprayed liquid particles out. Spraying head (160) incorporates a duct to force air, air inlet and liquid feed duct. Each aforesaid duct comprises, at least, one nozzle open on to the spraying zone and a device to adjust the liquid feed duct nozzle position relative to forced air feed duct nozzle. The proposed spraying method comprises the following stages, i.e. sucking in liquid from the vessel, forcing sprayed liquid into spraying zone, discharge of liquid sprayed particles from spraying zone into the vessel right above the liquid level in the said vessel, escape of a part of sprayed liquid particles from the vessel, sucking air into the vessel, forcing air sucked into the vessel into spraying zone.

EFFECT: liquid particles finely dispersed in air.
