The invention provides a CO2 capturing and storing system for an LNG power ship. The CO2 capturing and storing system comprises an LNG supply unit, a CO2 capturing and liquefying unit, an intermediate medium circulating unit, a high-temperature cylinder sleeve water supply unit and a liquid CO2 storing unit. The LNG supply unit comprises an LNG fuel cabin, an immersed pump, a first buffer tank, a marine main engine and a ventilation mast, the CO2 capturing and liquefying unit comprises a carbon capturing system, a compressor, a seawater cooler and a throttling valve, and the intermediate medium circulating unit comprises an intermediate medium heater, an LNG vaporizer, an LNG heater, a CO2 condenser, a first intermediate medium pump and a second intermediate medium pump. According to the system, stable LNG supply of the marine main engine can be achieved, cold energy released in the LNG heating and vaporizing process can be applied to condensation and liquefaction after CO2 capture, and the energy consumption of the system is reduced.

    本发明提供一种LNG动力船舶CO2捕集及存储系统,包括LNG供给单元、CO2捕集及液化单元、中间介质循环单元、高温缸套水供给单元和液态CO2存储单元;LNG供给单元包括LNG燃料舱、潜液泵、第一缓冲罐、船舶主机和透气桅,CO2捕集及液化单元包括碳捕集系统、压缩机、海水冷却器和节流阀,中间介质循环单元包括中间介质加热器、LNG汽化器、LNG加热器、CO2冷凝器、第一中间介质泵和第二中间介质泵。该系统不仅能够实现船舶主机的LNG稳定供应,而且能够将LNG加热汽化过程中释放的冷能运用至CO2捕集后的冷凝液化,降低系统的能耗。
