Abstract

The invention provides a compressed air foam-based intelligent fire-fighting device for an externally-floating-top crude oil storage tank. The compressed air foam-based intelligent fire-fighting device comprises fire-fighting cabinets and foam fire-extinguishing pipelines, wherein a compressed air foam system and a fire-fighting linkage controller are arranged inside each fire-fighting cabinet; the compressed air foam system comprises a gas energy storage tank, a mixed foam solution storage tank, a compressed air storage tank and a gas-liquid mixing device; the gas energy storage tank is communicated with the mixed foam solution storage tank through a driving pipeline; the mixed foam solution storage tank is connected with a liquid inlet of the gas-liquid mixing device through the foam solution conveying pipeline; a gas inlet of the gas-liquid mixing device is connected with the compressed air storage tank through a compressed air conveying pipeline; a foam outputting pipeline is connected to an outlet of the gas-liquid mixing device; the fire-fighting linkage controller is fixed to the fire-fighting cabinet and is eclectically connected with electrically controlled switching valves; the foam fire-extinguishing pipelines are circumferentially sequentially laid between the inner wall of the storage tank and the outer edge of a floating plate at intervals; a plurality of closed nozzles are formed at intervals in the length direction; the foam outputting pipelines of the fire-fighting cabinets are communicated with the foam fire-extinguishing pipelines.

Description

technical field

[0001] The invention belongs to the technical field of fire protection for crude oil storage tanks, and in particular relates to a compressed air foam intelligent fire protection device for crude oil storage tanks with external floating roofs. Background technique

[0002] Due to the large fluctuations in crude oil prices in the international market, my country's crude oil reserves are also increasing day by day. Tanks are the most efficient way to store crude oil. At present, my country's storage tanks are developing rapidly, and tend to be large and dense, and the safety of storage tanks has become one of the focuses of research. Compared with fixed-roof storage tanks, external floating-roof storage tanks greatly reduce the pollution and loss of oil products, reduce the possibility of storage tank fires, and greatly reduce the cost compared with internal floating-roof storage tanks, making them a The most widely used crude oil storage tank. The floating ...
