COMBINED UNIT OF FIRE - EXTINGUISHING OF OIL B VERTICAL STEEL RESERVOIRS OF LARGE CONTAINER AND THEIR BANKINGS UP

摘要

Combined installation extinguishing fires in oil tanks vertical steel (RVS) of large capacity and obvalovaniya relates to oil quenching oil agents and can be employed in the oil industry. PBC is equipped with an additional valve discharge oil pipeline with isothermal module with carbon dioxide and the container with extinguishing powder composition. The pipeline inside the tank is connected with the ring pipeline having a nozzle for discharging gas-dispersed mixture. The tank is equipped on the outside with an external annular penoprovodom foam nozzles, which is connected to penoprovodom connected to a metering unit intended to enhance foam stability. Penoprovod inside the tank is rigidly connected to a wiring duct, attached to the floating plate, and foam nozzles. Thus penoprovody and gas pipelines have separate solenoid valves. Technical result is achieved by simultaneous quenching of the fire with foam as the oil supply in the bottom of the tank and embanking and gas-dispersion mixture from the top of the tank. As a result, the formation of layers of foam and the gas-dispersed mixture and terminating the access of atmospheric oxygen the fire stops.
