Technical Problem
对于小型核动力装置，蒸汽朗肯发电技术非常成熟，发电效率为10%～30%，输出功率1～100MWe，但缺点是系统组成比较复杂，需要配套抽真空设备、除盐设备、除氧设备、加药系统、滑油系统以及造氧装置等
Benefits of technology
[0010]从蒸汽发生器出来的蒸汽进入汽轮机膨胀做功，推动发电机发电并输出电能，做功后的蒸汽经冷凝器冷凝成凝水，后依次通过凝水泵和给水泵加压后，返回蒸汽发生器，以此形成完整的热力循环。针对现有核动力装置蒸汽朗肯循环系统配置复杂、体积大，无法满足未来水下采矿用小型化需求的难题，本实用新型充分利用水下无人等特殊运行场景，在保证安全可靠的前提下，对蒸汽朗肯循环系统进行了紧凑性设计：1）由于水下无人，取消造氧装置；2）在舱室内充满氮气或其他惰性气体，汽水循环系统无氧化运行，取消除氧装置；3）循环系统管道采用耐腐蚀的不锈钢材料，结合无氧条件，取消除盐设备和加药装置等一系列水化学相关设备；4）采用电磁轴承技术，取消汽轮机润滑油系统及相关的滑油加热、滑油冷却、油气分离、滑油贮存等装置；4）精确分流凝水，通过凝水直接冷却发电机、电动机、电磁轴承、抽气器等设备，无需引入外部冷却剂，从而取消淡水冷却系统。通过以上设计，极大精简蒸汽朗肯循环系统配置，节省布置空间，以满足水下采矿用核动力平台狭小舱室空间的要求。
