3.1产品简介
移动式氢复器是二十世纪九十年代为压水堆核电站ETY系统所设计,用于消除安全壳设计基准事故后可燃氢气的安全设施。为实现多机组安全设备的资源共享,该产品整个系统布置于可移动车体上,外部接口备有快接接头,能够实现快速移动,快速接插。
移动式氢复合装置由全屏蔽消氢风机、冷却冷凝器、汽液分离器、催化反应器、冷却器和电气控制柜等组成。除电气控制柜外的所有设备安放在一个可以移动的小车上。该装置的设计、制造和检验符合ASME规范中核二级的要求。仪器仪表电气符合1E、K3的要求。
在2002年产品鉴定会上与会核电专家给与了“白,达到水平”的较高评价,认为该产品具有如下技术优势:
①采用于式去除有害杂质和高性能的消氢催化剂实现在较低温度下的消氢,使氢复合器具有消氢效率高、能耗低、运行安全可靠;
②采用全屏蔽涡旋消氢风机和装置总体布置的紧凑型设计实现了车载化,使氢复合器体积小重量轻、使用方便;
③采用压力平衡原理,配合液位控制、电磁阀组和合适的控制电路实现了自动排水功能,能够保证在排水过程中放射性气体不泄漏。
④选用磁釉真空烧结封口的U彩管状电加热元件,杜绝了因长期存放造成的绝缘电阻降低的现象,提高了设备使用的可靠性。
其*可靠的工艺、新颖合理的结构设计取得了国家,号为ZL.0,2004年获国防科工委科技进步二等奖。
移动式氢复合器广泛适用于压水堆核电站的安全壳ETY系统的消氢,可以作为新建核电站,包括百万瓦级核电站的选用对象。该产品已成功应用于秦山二期、方家山一期、福清一期、红沿河一期、宁德一期、阳江一期、防城港一期等核电站,运行稳定,性能可靠,获得用户好评。
