摘　　要：分子筛加热系统是分子筛正常运行的一个重要组成部分。目前大多数空分装置分子筛加热都采取蒸汽加热或与电加热器串联加热的方式,达到分子筛再生的目的。介绍了某空分装置分子筛纯化系统,该系统蒸汽加热与电加热器串联使用时,通过控制系统优化电加热器加热时间比例,既避免了富余蒸汽资源的浪费也能更好地节约电能。The molecular sieve heating system is an important part of the normal operation of the molecular sieve. At present, most of the molecular sieve heating in the air separation unit adopts steam heating or heating the regeneration gas in series with an electric heater, in order to achieve the purpose of molecular sieve regeneration. The molecular sieve purification system of an air separation unit is introduced. When steam heating and electric heaters are used in series, the heating time ratio of the electric heaters is optimized through the control system, which not only avoids the waste of excess steam resources, but also saves electricity better.
