FLUID ATOMISATION AND DEVICE TO THIS END Russian patent published in 2014 - IPC B05B17/00 

FIELD: process engineering.

SUBSTANCE: invention relates to atomisation of fluids, for example, pesticides and/or other physiologically active substances including bacterial and virus preparations and can be used in forestry, agriculture, cattle breeding, health protection, etc. In compliance with this process, fluid injection is executed in nozzle throat with supercritical pressure difference of supersonic flow through two split injectors arranged in compressed air flow direction in two atomisers. Device to this end incorporates built-in system of process control with supersonic flow pressure difference pickup, weather station and video camera. Besides, this device comprises diesel engine with single-stage booster as a compressor, air duct, fluid flow rate controller and flow meter. Also, it incorporates electrical and pneumatic independent systems. Air duct consists of two bends spinning relative to each other and around vertical axis in horizontal plane. Air duct communicates compressor with two atomisers. Flow meter serves to vary spray mist composition.

EFFECT: higher homogeneity of spray, better dispersion, control over dispersion, higher efficiency, non-polluting process.
