Abstract

本发明涉及化工自动化技术领域,具体为一种氩气自动切换连续不停气供气系统,包括气源模块,气源模块包括液氩真空储罐和多参数联锁控制系统;所述液氩真空储罐管路连接空温式气化器,空温式气化器后端连接气体缓冲罐,气体缓冲罐输出端连接氩气调压阀组;所述液氩真空储罐包括储罐本体和自增压控制系统,液氩经自增压控制系统增压至1.0MPa后进入空温式气化器完成气液转化,气化后的氩气经氩气调压阀组减压至0.65MPa后供给用气终端电渣炉;该系统结合了储罐自身重力自排液与自增压器被动汽化增压两种模式。当储罐压力尚可但流量不足时,依赖重力自排;当压力低于工况阈值时,触发自增压控制系统利用环境余热进行汽化增压。
