A method for forming a cloud of liquid droplets dispersed in the atmosphere having a controlled density of the cloud and the degree of polydispersity dispersion droplets and device for its realization

摘要

FIELD: methods and devices for spraying liquid in technological processes; farming and forestry. SUBSTANCE: proposed method includes dispersing liquid in nozzle disk followed by additional crushing of drops in toothed rims rotating in opposite directions in incoming air flow created by fan; then, drops are separated in field of centrifugal forces under action of air flow. After separation, coarse drops are accumulated and are delivered for repeated spraying; fine drops are carried by air flow into atmosphere through swivel nozzle for forming cloud. Device may be used for control of density of cloud and maintenance of dispersivity of drops within wide ranges: from aerosols to finely-dispersed drops and degree of polydispersivity by separation or selection of drops according to their sizes. Carry of jet of air from high- pressure centrifugal fan is equal to jet from supersonic nozzle at power reduced by 5-7 times. EFFECT: enhanced efficiency. 5 cl, 13 dwg
