摘要: 阻火器是一种用来阻止易燃气体和易燃液体蒸气火焰蔓延的安全装置,近年来已被广泛应用在石油化工、天然气等工业领域。随着现代社会的发展,人们对于安全问题越来越重视,因此,对于阻火器的性能测试就显得必不可少。由于我国在阻火器型式试验研究方向起步较晚,目前国内尚未有阻火器性能完整的测试系统。为完善阻火器的性能测试,本文开展了阻火器性能测试试验系统的研制工作,以提高我国在这一领域的检测水平。系统能够完成试验所需的爆炸性混合气体的配置工作,气体燃烧爆炸过程中的压力、火焰速度及温度的测试工作,数据的分析处理工作。试验系统包括配气装置、传感器检测系统、数据采集装置。配气装置可以实现静态、动态混合配气的要求。传感器检测系统可完成火焰识别、温度采集、压力采集功能。数据采集装置可对数据进行处理,实时显示实验过程数据,并记录、处理试验数据。测试系统充分考虑了试验现场的安全性,测试精度完全满足阻火器型式试验的要求,且系统操作简单、方便、运行可靠,完成了多次阻爆测试和耐烧测试,其效果达到国家相关标准的要求。

Abstract: Flame arrester is a kind of safety equipment which can prevent flammable gas and liquid vapors from spreading,and widely used in petrochemical and natural gas industry in recently years. In order to improve the flame arrester performance testing and detection level,this research focused on flame arrester performance testing system. The system designed was able to complete the test configuration of explosive mixture gas,explosion process pressure,flame velocity and temperature testing work,the analysis of the data processing work. The testing system included gas mixing apparatus,sensor detection system,data acquisition device. Gas mixing apparatus can realize the request of static-dynamic mixing with gas. Sensor detection system can achieve the function of fire recognition,temperature detection and the pressure detection. Data acquisition device can realize processing data,displaying experiment data in real-time,recording and processing the test data. The testing system considered sufficiently the security issues of the testing scene,and the testing precision can completely satisfy the testing requirements of flame arrester. This system was stable,reliable and quite simple in operation and met the national standards.

Key words: flame arrester, safety, performance testing system, gas mixing apparatus, sensor detection system, data acquisition device
