DEVICE FOR EXTINGUISHING FLAMMABLE LIQUIDS IN VERTICAL TANK WITH FLOATING ROOF OR PONTOON Russian patent published in 2012 - IPC A62C3/06 B65D88/34 

FIELD: fire-prevention facilities.

SUBSTANCE: invention relates to the field of fire fighting technology and can be used to extinguish fires in vertical tanks with floating roof or pontoon, designed for storage of flammable liquids. The device for extinguishing flammable liquids in a vertical tank with a floating roof or pontoon comprises a vertical tank with a floating roof or pontoon. Inside the tank there are vertical pipelines for supply the extinguishing agent. Start- locking device is connected to the vertical pipelines for supply the extinguishing agent. In the tank the floating roof or pontoon are fixed by two or more rigidly attached in it vertical guide racks with the ability of free reciprocating movement in the vertical plane of the tank. Each rack stand is a pipe the lower end of which is tightly fixed to the bottom of the tank and the upper end is sealed with a flap. The vertical pipelines for supply the extinguishing agent are tightly mounted inside the respective guide racks. In racks the holes are made opposite the exits of nozzles for spraying extinguishing agent. The side layouts are located under the floating roof or pontoon with height of pipelines for supply the extinguishing agent. The first side layout with fully filled tank is located in the vicinity of the lower surface of the floating roof or pontoon.

EFFECT: implementation of subsurface fire extinguishing and reducing the likelihood of damage of fire-fighting equipment in the fire.
