UNIT OF GASEOUS FIRE SUPPRESSION FOR PLACES OF STORING CONTAINERS WITH FLAMMABLE AND COMBUSTIBLE LIQUIDS IN TEMPORARY SETTLEMENT OF POPULATION AFFECTED BY EMERGENCIES Russian patent published in 2015 - IPC A62C3/00 

FIELD: fire safety.

SUBSTANCE: in the unit of gaseous fire suppression for places of storing containers with flammable and combustible liquids in temporary settlement of population affected by emergencies, comprising a control unit and series-connected insulated tank for liquid carbon dioxide with the pipeline of supplying carbon dioxide and lock and release device located outside the tank, the switching gears and the distribution pipeline with sprayers. The lock and release device is located above the level of liquid carbon dioxide in the tank, and the intake of carbon dioxide is carried out through the pipeline in the tank from the bottom part of the latter, each nozzle housing is formed with a channel for supplying liquid and comprises a housing in which the screw is pressed, and a fitting for supplying liquid, and the housing consists of two coaxial interconnected cylindrical sleeves: the sleeve of larger diameter and the sleeve of smaller diameter, and the inside the sleeve of smaller diameter, coaxially to it, a screw is mounted, rigidly connected to its inner surface, such as pressed in it, and the outer surface of the screw is a helical groove and inside the screw a hole with a screw thread is made, and in the sleeve of larger diameter coaxially to it, the fitting is located, fixedly mounted in it, such as by the threaded connection through the sealing gasket, and in the fitting a cylindrical opening is coaxially formed passing into axially located diffuser which is connected to a cylindrical chamber formed by the inner surface of the sleeve of smaller diameter and the end surface of the screw, and the end surface of the sleeve of smaller diameter is fixed to two obliquely located rods, on each of which active sprayers are secured, for example made in the form of blades resting in the lower part on stops fixed to the rods perpendicular to their axes. The rods are tilted in the direction away from the axis of the injector, i.e. along the conical surface which apex is directed towards the sleeve of the larger diameter.

EFFECT: increased efficiency of fire-extinguishing.
