气相爆轰实验系统设计

Gaseous Detonation Experiments System Design

设计了一套内径139 mm、总长10 m的气体、粉尘爆轰管道式反应装置,装置由试验管道系统、测试系统、辅助实验系统和控制系统4部分构成。测试系统包括高频响动态压力传感器、火焰传感器、超动态应变仪、数据采集卡、高速摄像系统等设备,以便测试可燃气体、粉尘的爆轰参数和管道的动力学响应特征参数。实验装置可用于可燃气云和粉尘的燃烧、爆炸特性以及爆轰波对结构加载作用的研究,研究成果可用于燃气输送管道的设计、校核,为安全生产保驾护航。

A set of gas- dust pipeline detonation reactor is designed,which has an inner diameter of 139 mm and a length of 10 m. The device is composed of four parts： the piping system,test system,auxiliary system and control system. The test system is made up of high frequency dynamic pressure sensors,flame sensors,ultra- dynamic strain gauge,data acquisition cards,high- speed video analysis system,etc,easily to test detonation parameters of combustible gas or dust and dynamic response characteristics of pipeline. This device could be used in research for combustible gas or dust burning,explosion characteristics and structure load action under detonation wave,the results can be extended to the designing and checking of gas transmission pipeline,and provided for safety production.
