摘　　要：在煤化工测量领域,有一种令工程师较为棘手的测量现场,就是一些具有较强腐蚀性酸碱盐液体和含有固体颗粒介质的压力、液位测量,极容易导致仪表取压管线堵塞结晶。该类测量仪表相较于常规的测量要求较高,有的甚至就无法进行。随着我国仪表自动化的不断发展,为进一步提高仪表融合应用,将其使用的价值充分发挥出来,并研究其在煤化工中的应用效果。鉴于煤化工装置介质黏度大、易凝、易结晶和易腐蚀的工艺特点,该文首先报告煤化工企业特殊工况仪表运行所存在的问题与改造方式,阐述目前吹扫装置及吹扫型雷达物位计的工作原理及技术优势,最后提出煤化工反吹风仪表改造创新点及应用效果。In the field of coal chemical industry measurement,there is a kind of measurement site that makes engineers more difficult,that is,some pressure and liquid level measurements with strong corrosive acid,alkali and salt liquids and media containing solid particles,which can easily lead to blockage and crystallization of instrument pressure lines.Compared with the conventional measurement,this kind of measuring instrument has higher requirements,and some of them can not even be carried out.With the continuous development of instrument automation in our country,in order to further improve the application of instrument integration,give full play to the value of its use,and study its application effect in coal chemical industry.In view of the process characteristics of high medium viscosity,easy condensation,easy crystallization and easy corrosion in coal chemical plant,this paper first reports the existing problems and transformation methods in the operation of instruments under special working conditions in coal chemical enterprises.This paper describes the working principle and technical advantages of the current purge device and the sweeping radar level meter,and finally puts forward the innovation and application effect of the coal chemical reverse blowing instrument.
