Study On Simulation Modeling And Experimental Of High Pressure Water Mist Fire Extinguishing System

With the development of society and the progress of science and technology,people's quality of life requirements are getting higher and higher.Accompanied by a variety of buildings where they stand,people's lives become more convenient and fire safety is always threaten.This is a huge challenge to fire technology.At the same time,halogenated hydrocarbons,used widely last century,because of environmental pollution,was gradually banned,anxious to find a safe and reliable way to become the world's competing research.The high-pressure water mist fire extinguishing technology because of its use of natural water for fire,with environmental pollution,and spray the water droplets very small,high efficiency fire extinguishing,more and more attention,is now widely known at home and abroad can replace halogenated hydrocarbon sunrise technology.Therefore,it is of great significance to carry out theoretical study,modeling research and experimental research on the improvement of fire level in high pressure water mist fire extinguishing system.This paper briefly introduces the development status and the latest research progress of high pressure water mist fire extinguishing technology at home and abroad,and on this basis,analyzes the basic principles of high pressure water mist fire extinguishing,the characteristics and advantages of fire fighting.At present,researchers at home and abroad are often a part of the system to establish a model of research,few software to build a complete system simulation model.Therefore,this paper finally identified the use of Anylogic and FDS two softwares to establish a high pressure water mist fire extinguishing system package model of the research program.In this paper,Anylogic through the establishment of high pressure water mist fire extinguishing system control simulation model.It not only greatly reduce the high pressure water mist fire extinguishing system to study the cost of equipment investment,but also to make up the whole system after the actual installation and commissioning after the poor mobility,the high cost of shortcomings.At the same time,the system dynamics content can be better applied to high pressure water mist fire extinguishing system.This paper presents a simulation model of high pressure water mist fire extinguishing system based on Anylogic system dynamics.The model provides an important model basis for the development and improvement of high pressure water mist control technology in China.At the same time,this project established a FDS based high pressure water mist indoor fire extinguishing effect model.The establishment of this model can be used to study the impact of various factors on the fire extinguishing effect during the high-pressure water mist fire extinguishing process.By cooperating with the Anylogic system control model,the working condition of the high pressure water fog system can be fully demonstrated,which greatly reduces the research cost of the technology and improves the research progress of the high pressure water mist fire extinguishing system.In this paper,a high pressure water mist fire extinguishing experiment platform is established.For the confirmation of Anylogic model and FDS model,the experiment is carried out repeatedly.The feasibility of the model is verified by comparing the experimental results with the simulation results.After contrasting the difference between the two effects,and then modify and refine this model,until the basic can be achieved in the computer to complete the level of high pressure water mist fire research.Finally,this paper makes a simple prospect about the follow-up work of high pressure water mist fire extinguishing system and modeling.
