Problems solved by technology
[0004] The compressed air foam fire extinguishing system in the related art does not start manually until the staff confirms the fire and starts to prepare the compressed air foam. The fire extinguishing foam cannot be quickly covered on the fire, and it takes at least 1 minute to complete the fire extinguishing, which delays the best time to extinguish the fire

The disclosure discloses a fire extinguishing device and a fire extinguishing system, which belong to the technical field of fire extinguishing of oil storage tanks. Including: a plurality of fire extinguishing devices arranged on the floating plate of the outer floating roof oil storage tank at intervals in the circumferential direction, the fire extinguishing device includes: a plurality of closed nozzles, a pressurized gas storage bottle, a fire extinguishing agent storage bottle, a first valve, The second valve, the pressure switch, the liquid level switch, the first junction box and the arc tube. The outlet of the pressurized gas storage bottle is communicated with the inlet of the first valve, the outlet of the first valve is communicated with the air inlet of the fire extinguishing agent storage bottle, the outlet of the fire extinguishing agent storage bottle is communicated with the inlet of the second valve, and the second valve The outlet is communicated with the arc-shaped pipe, a plurality of closed nozzles are evenly spaced on the arc-shaped pipe along the arc direction of the arc-shaped pipe, and the arc-shaped pipes are arranged along the circumference of the floating plate of the outer floating roof oil storage tank. The pressure switch and liquid level switch are mounted on the extinguishing agent storage bottle. The fire extinguishing system can quickly detect fires and extinguish the initial fires in time.
Description
technical field [0001] The present disclosure relates to the technical field of fire extinguishing of oil storage tanks, in particular to a fire extinguishing system. Background technique [0002] External floating roof storage tanks have external floating roofs that rise or fall with the level of storage. Compared with the fixed roof storage tank without floating roof, there is no space for oil evaporation, which reduces the pollution and loss of oil products, and is the most widely used crude oil storage tank. The floating plate of the external 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, so that its performance is 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 fire of the sealing ring is not e...
