小型制氢装置过程控制系统设计 小型制氢装置过程控制系统设计 摘 要 氢气在工业上有着广泛的用途，随着科学技术的日益发展，人们对氢能 源、环境、经济等的认识越来越深刻。而且，近年来，半导体工业、非晶硅太 阳电池、化学工业、光导纤维工业的迅速发展，氢的用途越来越广泛，需求量 越来越大，同时，对氢的纯度要求越来越高。氢是制备集成电路不可缺少的气 体，氢能是人类生存和经济持续发展的可靠能源。研究自动控制系统在制氢装 置中的应用。由于在许多工业中,工艺上要求两种或两种以上的物料保持一定比 例关系，所以，在这套制氢装置中应用比值控制系统来实现对原料的控制保持 一定比例关系。 关键词：氢气，氢能源，自动控制系统，比值控制。 - I - 小型制氢装置过程控制系统设计 Abstract The hydrogen has got the extensive use on the industry,Along with science technical develop increasingly, people are more and more deep to the cognition of the hydrogen energy, environment, economic etc..And, in recent years, industrial and quick development in industry, optic fiber in industry, chemistry in semi-conductor, the hydrogenous use is more and more extensive, the demand is more and more big, at the same time, is more and more high to the hydrogenous and pure a request.Hydrogen is dependable energy that the air that the system has the integrated circuit indispensability, the hydrogen can be mankind to exist to keep on developping with the economy. Studying the automation the system in made hydrogen equip of application. Because in many industries, on the craft requesting two kinds of or more than two materials keeps certain comparison relation，so, making the hydrogen equips, apply the specific value control system, make the raw material keep the certain comparison relation. Key Words Hydrogen, Hydrogen energy,Automatic control system， Specific value control. - II - 小型制氢装置过程控制系统设计
