DEVICE TO EJECT FLUID BY BLOWN AIRFLOW Russian patent published in 2014 - IPC B05B7/00 

FIELD: process engineering.

SUBSTANCE: invention relates to ejection of various fluids, particularly, water by blown airflow and can be used in enforcement of law, environmental protection and agriculture. Proposed device comprises several extra satellites, each including one premixing chamber. Said satellites are arranged around secondary air cowling. Engine comprises fluid ejector making a compressed airflow generator, secondary air being ejected at high flow rate in secondary air channel. Compressed air bleed pipe or pipes are connected to said channel. Dual-flow reactor makes the airflow generator and includes fluid flow ejector. Proposed method comprises creating blown airflow by bypass gas turbine engine. Said engine is supplied with ambient air and includes secondary compressed air channel. Said channel is arranged around central housing supplied with primary compressed air. Blower driven by motor or gas turbine engine is built in central housing. Compressed air is bled in secondary compressed air channel to supply one or several premixing chambers. Chambers are supplied with fluid to be ejected for it to be sprayed together with bled compressed air in ambient medium.

EFFECT: higher efficiency of mixing, high-quality sprayed air and fluid, higher efficiency of fire extinguishing.
