【技术实现步骤摘要】
【国外来华专利技术】
本专利技术涉及一种用第二回路或容器中的第二流体压力来平衡第一回路或容器中的第一流体的压力的被动设备。本专利技术还涉及使用该设备来平衡两种热交换流体的压力。
技术介绍
在一些工业领域用到数种流体例如气体,将该流体装在容器中或者使之循环以便在一个装置中使用,在该装置中要求这几种流体压力相同或至少彼此压力相差不大。例如,在利用高温核反应堆产生的热量来发电的设备中,用到热交换器例如板式热交换器,热交换器被设计来接受一种气体例如氦气,作为第一热交换流体用来冷却核反应堆堆芯,以及接受一种含氮气体例如空气,作为第二热交换流体用于驱动气体透平和使水沸腾产生蒸汽透平用的蒸汽。FRAMATOME ANP在2002年4月12日申请的法国专利申请No.02/04638中,描述了一种这样的发电的设备和相应的方法。在这样的一种装置中使用热交换器例如板式热交换器时,在该装置的所有的运行阶段,希望确保有着两种热交换流体的热交换器以几乎相同的压力运行。在上述以FRAMATOME ANP为申请人的专利申请所描述的装置中,其中一次侧氦气和二次侧热交换气体的压力接近60bar,在该装置的正常运行期间,必须确保分隔一次侧氦气和二次侧热交换气体的热交换壁的两侧压力永远不超过5bar。此外,不能接受时间压力梯度超过每60秒5bar。在与一个事件或事故相关联的状态下(例如正在进行热交换的其中一个回路中如果发生管道破裂事故),必须能够在很短的时间内,突然承受大约60bar的压差。在稳态运行时,两种热交换气体的压力通常保持在一些界限内,以使穿过热交换器壁的临界压差永远不会达到。在瞬态下同样也不会出现,甚 ...
