DUST CONTROL METHODS AND SYSTEMS Russian patent published in 2020 - IPC E21F5/02 C09K3/22 G01N13/02 B05B12/12 

FIELD: devices for spraying or spraying liquids; ecology.

SUBSTANCE: invention relates to dust control method. Method involves obtaining a water-based liquid stream containing one or more of the following types of water: tap water, water from the well, pond water, river water, waste water, recycled water from an industrial process, obtaining an aqueous dispersion stream by feeding a surface-active composition into a water-based liquid stream, mixing the stream of the aqueous dispersion to form a dust suppressor, measuring the surface tension of the dust suppressor using a strain meter, transmitting the results of measuring surface tension to the controller, controlling the formation of the aqueous dispersion stream according to measurement results transmitted to the controller and spraying the dust suppression aerosol onto the surface of the produced product, wherein the aerosol spray has an average droplet size of about 0.1 mcm to about 100 mcm.

EFFECT: higher efficiency of dust suppression, reduced threat to health of people, for environment and fire safety.
