The invention provides a passive residual heat removal system suitable for a nuclear power icebreaker. A steam generator is used for generating steam. The air outlet pipe is connected to the steam generator and used for discharging steam. The first steam stop valve is arranged on the air outlet pipe and is configured to be closed when a circuit of the icebreaker is powered off. The heat exchange box is configured to store water when the environment temperature of the icebreaker is larger than a first preset temperature and store air with preset pressure when the environment temperature is smaller than or equal to the first preset temperature. The heat exchange device is arranged in the heat exchange box, and an inlet of the heat exchange device is configured to be communicated with the steam generator when a circuit of the icebreaker is powered off. An outlet of the heat exchange device communicates with the steam generator so that condensate water formed after steam cooling can return to the steam generator. The blasting device is configured to enable the top wall and the bottom wall of the heat exchange box to be blasted when the environment temperature is smaller than or equal to the first preset temperature and the circuit is powered off, and further external air is exhausted from the top wall after entering the heat exchange box from the bottom wall.
本发明提供了一种适用于核动力破冰船的非能动余热排出系统,蒸汽发生器用于产生蒸汽。出气管连接于蒸汽发生器,用于排出蒸汽。第一蒸汽截止阀设置于出气管,并配置成在破冰船的电路断电时关闭。换热箱配置成在破冰船所在的环境温度大于第一预设温度时储存水,在环境温度小于或者等于第一预设温度时储存预设压力的空气。换热装置设置于换热箱内,换热装置的入口配置成在破冰船的电路断电时与蒸汽发生器连通。换热装置的出口与蒸汽发生器连通以使蒸汽降温后形成的冷凝水返回蒸汽发生器。爆破装置配置成在环境温度小于或者等于第一预设温度且电路断电时使换热箱的顶壁与底壁爆破,进一步使外界空气从底壁处进入换热箱后,再从顶壁处排出。
