UNIT FOR DYNAMIC DUST SUPPRESSION Russian patent published in 2016 - IPC E21F5/02 

FIELD: machine building.

SUBSTANCE: unit for dust suppression is suggested, is comprised a control block, made with a possibility of signal transmission to a HP air source, connected by discharge air ducts with bellows type tanks with ionised water of opposite polarity via solenoid pneumatic valves, fine spraying atomisers, connected by water lines with the bellows type tanks via solenoid hydraulic valves, and an isolation device of air and water lines, connected with the HP air source by a blowing pipeline, wherein the solenoid pneumatic and hydraulic valves and isolation device are connected by control and monitoring circuits with the control block. Wherein in the bellows type tanks perforate bubble air ducts are installed through their full depth with a pneumodynamic generator of air pressure oscillations at the input.

EFFECT: increased efficiency of dust suppression due to the significant increasing of the dynamic pressure of the air-water mixture on dust particles, and its improved wettability to increase the efficiency of gravity forces facilitating dust quicker deposition.
