摘　　要：以煤粉爆炸特性参数测试为基础,针对煤化工煤粉制备系统的运行工况条件,应用煤粉爆炸特性关键参数对压力、温度、煤粉浓度、氧浓度等主要安全监测监控参数指标进行了研究,分析了监测点布置位置与测量范围及报警值设置的合理性与存在的安全隐患,并提出了其改进措施,提高了粉体介质在工艺生产中的可控状态,对煤化工行业控制煤粉泄露、燃烧爆炸等事故具有一定的借鉴作用。Based on the test of pulverized coat explosion characteristic parameters, according to coal chemical pulverized coal preparation system operating conditions, the key parameters such as pressure, temperature, pulverized coal concentration, oxygen concentration and other main safety monitoring parameters were studied by using the key parameters of pulverized coal explosion. This paper analyzedthe location and measurement range of the monitoring point, the reasonableness of alarm value and the existence of security risks. Then, it put forward measures to improvethe controllable state of powder media in process production, which have a certain reference for coal chemical industry to control the leakage of coal, combustion and explosion accidents.
