METHOD OF FIRE-FIGHTING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC A62C31/02 B05B1/14 

FIELD: fire-fighting equipment.

SUBSTANCE: invention relates to the field of fire-fighting equipment, is designed for fire-fighting with automatic stationary or mobile units by fine spraying of fire-extinguishing liquid, and can be used on objects of equipment or munition demilitarisation. The device for fire-fighting consists of a cylinder with fire-extinguishing liquid, locking-trigger assembly for supplying fire-extinguishing liquid to the sprayers, fire alarms and power drive of the locking-trigger assembly. The fire-extinguishing liquid is in the cylinder under pressure of the compressed gas. The cylinder with the fire-extinguishing liquid has two flanges and is located vertically. The lower flange is attached to the cassette with liquid carbon dioxide, which has fluid communication with the cavity of the cylinder. On the other cylinder flange the intake of fire-extinguishing liquid in the form of a tube is secured. The inlet of the tube is situated near the lower flange of the cylinder. To prevent the liquid carbon dioxide enter into the intake its inlet is located in the cavity of the reflecting screen, made in the form of a cup. The cylinder and the cassette with liquid carbon dioxide are located in a thermostatic container. Displacement of the fire-extinguishing liquid is carried out under the constant pressure of carbon dioxide above the mirror of the liquid through the locking-trigger assembly mounted on the intake, into the distribution main pipe-line. At the outlet of the main pipe-line the multitiered chain of multi-nozzle heads is located with centrifugal nozzles. To start the unit in operation the locking-trigger assembly has a power drive, which is started in operation by the signals from the sensors of fire.

EFFECT: increasing fineness of spraying of the fire-extinguishing liquid, increasing its heat absorbing properties and ensuring constant flow rate of fire-extinguishing liquid in the process of fire extinguishing.
