Linkage control system and method for extinguishing fire through heptafluoropropane gas

Abstract

The invention discloses a linkage control system for extinguishing fire through heptafluoropropane gas. The linkage control system comprises a gas extinguishing device, a fire detection device, an oxygen concentration detection device, a carbon monoxide concentration detection device, a hydrogen sulfide concentration detection device, a monitoring device containing an infrared camera and a control system, and has the advantages of reducing loss caused by the fire and the like. The linkage control system can monitor the oxygen concentration of the surrounding environment in real time, and reduce the situation that due to the fact that the oxygen concentration in an area is too low, the life safety of people is harmed; and meanwhile, through the fire extinguishing device structure, comprehensive multi-angle fire extinguishing can be conducted on the indoor fire, and the situation that due to the fact that air flow at dead corners is insufficient, the fire cannot be extinguished is prevented. Due to the structure, when multiple nozzles rotate, the vertical reciprocating swing action can be achieved, the fire extinguishing range is further enlarged, the production cost is saved while driving elements are saved, and the fire extinguishing effect is improved.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a linkage control system and method for using heptafluoropropane gas to extinguish fires. Background technique [0002] At present, most of the fires in buildings are extinguished by water fire extinguishing system, but for electrical fires, such as power distribution room, substation room, communication room, etc., water fire extinguishing system is not suitable, and heptafluoropropane gas fire extinguishing system mainly It is used in an environment that is not suitable for setting up other fire extinguishing systems such as water fire extinguishing systems. The gas fire extinguishing system refers to the fire extinguishing agent that is usually stored in a pressure vessel in a liquid, liquefied gas or gas state, and is sprayed in a gas state as a fire extinguishing medium when extinguishing a fire. system, and can form a uniform gas concentration in all directions in t...

Problems solved by technology

[0002] At present, most of the fires in buildings are extinguished by water fire extinguishing system, but for electrical fires, such as power distribution room, substation room, communication room, etc., water fire extinguishing system is not suitable, and heptafluoropropane gas fire extinguishing system mainly It is used in an environment that is not suitable for setting up other fire extinguishing systems such as water fire extinguishing systems. The gas fire extinguishing system refers to the fire extinguishing agent that is usually stored in a pressure vessel in a liquid, liquefied gas or gas state, and is sprayed in a gas state as a fire extinguishing medium when extinguishing a fire. system, and can form a uniform gas concentration in all directions in the space of the protection zone, and at least maintain the fire extinguishing concentration to reach the immersion time specified in the specification, so as to extinguish the space and three-dimensional fire in the protection zone. Most heptafluoropropane gas fire extinguishing systems use induction Smoke detectors or heat detectors are used to detect fires. Due to the lack of intelligence in the existing fire extinguishing systems and the limited spraying range of fire extinguishing nozzles, it is impossible to fully extinguish the fire. At the same time, people cannot immediately and accurately know whether a fire has occurred, and the indoor environment cannot Timely monitoring, in addition, the heptafluoropropane gas fire extinguishing system can only detect the fire after the fire occurs, but cannot judge the fire in advance, lacking the ability to predict the fire

Part of the fire extinguishing gas will dilute the air after being sprayed out, which will reduce the oxygen concentration in the surrounding environment, and the fire smoke contains a large amount of toxic gas, which is not conducive to people's breathing, which seriously threatens the life safety of staff or firefighters.
