College Fire Safety And Security Of Laboratory Construction Of The Automatic Sprinkler System Experiments

Along with the major fire occurred frequently in our country recent years, moreand more people pay attention to the fire problem and many universities also haveopened fire engineering profession. But the textbook knowledge already can’t keep upwith the development of the society and students also can’t understand deeply. As aresult, the school builds the fire laboratory is to let the students understand deeply thetextbook knowledge through the practice, also lay the foundation to the future job. Inaddition, the school builds the fire laboratory is also to provide a platform forgraduate students, for deeper research.Based on the study of automatic sprinkler fire extinguish system, determining asystem type fit for the fire laboratory and coming up with how to select fire devicesproblem and so on. All the laboratory design must be accorded with the actualsituation and the function is perfect, but in some places, it doesn’t need to complywith requirement specification, in the contrary, it should be humanized and someimportant devices also should be installed on the place is easy to operate. Theautomatic sprinkler system is demonstrated in the glass room, the closed showernozzle and water distribution network is placed in the room and other devices on theoutside. The laboratory selects two system for demonstrating, the one is wet system,the other is deluge system, Because the two system used widely in actualconstruction.This article includes how to select the fire device, pipeline calculation and pipenetwork layout, in the last, through the CFAST software, simulating the smoke layerthickness, the fire temperature changes with the time, heat release rate and nozzleaction time in the room and so on.
