Abstract

The invention discloses a fire extinguishing device and a fire extinguishing system, and belongs to the technical field of oil storage tank fire extinguishing. The system comprises a plurality of fire extinguishing devices circumferentially mounted on a floating disc of an outer floating roof oil storage tank at intervals, and each fire extinguishing device comprises plurality of closed nozzles, a pressurized gas storage bottle, a fire extinguishing agent storage bottle, a first valve, a second valve, a pressure switch, a liquid level switch, a first junction box and an arc-shaped pipe. Gas outlets of the pressurized gas storage bottles are communicated with inlets of the first valves, outlets of the first valves are communicated with gas inlets of the fire extinguishing agent storage bottles, gas outlets of the fire extinguishing agent storage bottles are communicated with inlets of the second valves, outlets of the second valves are communicated with the arc-shaped pipes, and the closed nozzles are evenly arranged on the arc-shaped pipes at intervals in the arc direction of the arc-shaped pipes. The arc-shaped pipes are arranged along the circumference of the floating disc of the outer floating roof oil storage tank. The pressure switches and the liquid level switches are arranged on the fire extinguishing agent storage bottles. The fire extinguishing system can quickly detect a fire and extinguish the initial fire in time.

Description

technical field [0001] The present disclosure relates to the technical field of oil storage tank fire extinguishing, in particular to a fire extinguishing system. Background technique [0002] External floating roof tanks have an external floating roof that rises or falls with the level of the liquid stored. Compared with the fixed roof storage tank without floating roof, there is no space for oil to evaporate, which reduces the pollution and loss of oil products, and is the most widely used crude oil storage tank. The floating plate of the outer floating roof storage tank and the inner wall of the storage tank realize primary sealing and secondary sealing through the sealing ring. The sealing ring is in contact with the oil storage for a long time, making its performance aging, and oil leakage such as oil spills often occurs. Lightning strikes, static electricity, and open flames can easily cause the sealing ring to catch fire. If the sealing ring fire is not extinguished...
