MOBILE FIRE EXTINGUISHING UNIT Russian patent published in 2014 - IPC A62C13/64 

FIELD: fire safety.

SUBSTANCE: mobile fire extinguishing unit comprising a container with liquid, designed for fire extinguishing, a system of supplying pressurised liquid, a swirler of liquid flow with guide elements, a liquid atomiser connected through the feeding pipeline with the container, the atomiser housing is made in the form of a feeding fitting with the central opening and rigidly connected to it, and a coaxial cylindrical sleeve with an external thread, and the nozzle is connected coaxial to the housing, in its lower part, by the sleeve with internal thread, made in the form of a centrifugal swirler of liquid flow in the form of a cylindrical insert with at least three tangential inlets in the form of cylindrical openings, and the sleeve is a part of the nozzle and is mounted coaxially and in alignment in relation to the centrifugal swirler, in the end surface of which the cylindrical orifice is made, and the centrifugal swirler is mounted in the cylindrical chamber of the housing to form an annular cylinder chamber for supplying liquid to the tangential inlets of the centrifugal swirler and is connected to the diffuser outlet chamber, and tangential inlets are made in the form of channels located tangentially to the inner surface of the cylindrical insert, and the confuser is coaxially attached to the sleeve, the inner cavity of which through the openings made on its lateral surface connects its cavity with the outside air, and at the output of the confuser the throttle in the form of a cylindrical shell is fixed, which increases the jet range of the entire unit.

EFFECT: improving the efficiency of fire-extinguishing through fine droplets in the flow and range of feeding the gas-drop flow due to the compactness of the jet.
