, physical fire extinguishing system, automatic fire fighting -[Abstract] This article needs to be set large gas fire extinguishing system characteristics of high-rise building set, made of large high-rise building Fire extinguishing system The selection principle and market through our choice of comparative advantages and disadvantages of gas fire extinguishing system, how to select high-rise buildings made of large gas fire extinguishing system in the proposal of conclusions.
I. Introduction With IT The rapid development of industry, more and more high-rise buildings need to set up large gas fire extinguishing system. Set gas fire extinguishing system had been avoided due to fire caused by secondary loss process, but also brought the envelope structure, personnel safety, equipment investment and maintenance requirements of higher new problems. This requires designers to set the options selected when the fire extinguishing system should be on the various issues to be fully considered.
This article aims to start from the scientific method, the analysis based on the characteristics of high-rise building fire on several common objective analysis of gas extinguishing systems, and protection against high-rise building with different objects and different protected areas, to submit the appropriate division of setting program.
Because of limited, as described in the text View Not necessarily correct, hope you can get the treatise peers.
Second, a large gas fire extinguishing system be set on fire characteristics of high-rise building
Need to set up a large gas fire extinguishing system of high-rise building is generally the hub of the telecommunications industry, building Financial Building, electrical power management, libraries, archives building, such as radio and television building. Its main characteristic is more protected areas, protected areas, the geometric size of a single large floor span.
Building domestic gas fire extinguishing system above the main place to protect a computer rooms, clearing house, database room, archives and valuables bank, power distribution room and telecom switch rooms, transmission room, data Communicate Room, room measurements, network management center, wireless room, supply room and the power industry, electric power control center, power control center. Fire types are mainly Electrical Fire And Class A fires.
Above, usually because of electrical problems in building a fire, a fire early this category often have a greater smoke, so use a good smoke Probe Device to carry out the early fire detection is essential.
Formation and development of the fire there is a certain law, the initial fire extinguishing system is fighting an effective means.
According to specifications set in the above gas fire extinguishing systems in buildings is not controversial, but the reliability of gas fire extinguishing system worse than the water system. Because the gas fire extinguishing system is not only the reliability of the system itself, there are strict requirements, and to the protection zone and the protection of objects have a corresponding request. In the protection area to protect the integrity of damaged or object has changed, even the early fire can not guarantee that fire.
Let us design a fire, electrical cause as a protected area on fire, smoke detection devices to detect fire, rapid fire control room staff on duty to verify the fire protection district after the fire with portable fire extinguishers but failed to implement So outside of the emergency protective boot boot device, fire fighting system-related linkage moves correctly, in addition to relief estuary openings are closed in time, after the fire extinguishing system in the implementation of the delay spraying extinguishing agent release. Even so will result in two cases, one is fighting success; the other is the fire failed, fire unsuccessful mainly because: 1 protection area due to impatient and destroyed doors and windows; 2, window protection zone glass broken in the early heat of fire; 3, protective design of the district placed the items had not been taken into account and this item has been ignited.
Above design assumes that fire extinguishing system is fully working under the premise, even if such fire extinguishing system is not necessarily successful, the fire extinguishing system will immediately once the fire out of control and failed to spread outside the protection zone This will bring great disaster, because the high-rise building design ideas in the fire is based on the self, the self-help fail, the fire immediately to the flashover stage of transformation, this will cause the level above the burning layer can not protect consequences.
