DEVICE FOR PREVENTION OF FIRES, AS WELL AS SELF-EXTINGUISHING OF FLAMMABLE LIQUIDS IN STATIONARY CAPACITIVE EQUIPMENT WITH UNSTABLE LIQUID LEVELS Russian patent published in 2022 - IPC A62C3/06 

FIELD: fire protection.

SUBSTANCE: device is claimed for prevention of fires and self-extinguishing of flammable liquids in vertical steel tanks, reservoirs, reactors. The device contains a modular assembly of vertical channels with a given ratio of a height of a vertical channel H, not filled with liquid, to its equivalent diameter d_eq, which are placed inside a shell, to an outer perimeter of which, at an interval of no more than d_eq, vertical semi-channels are attached, capable of forming, in the assembly with a container, a closed sequence of perimeter channels. In this case, the device is made with the possibility of free movement inside the container. Moreover, the equivalent diameter of the vertical channel is set with a density and surface tension of liquid by developed dependencies.

EFFECT: increase in the efficiency of prevention of fires and self-extinguishing of flammable liquids in capacitive equipment with unstable levels of liquid.
