The invention provides an ammonia power super oil tanker cargo hold unloading and alternative inert gas supply system, which comprises three subsystems, namely an ammonia fuel supply system, an ammonia gas combustion system and an unloading and gas supply system, when a super oil tanker conveys crude oil from a cargo hold to a shore-based oil depot through an unloading pump at an unloading port; the unloading and gas supply system is adopted, the system can introduce ammonia gas obtained after ammonia fuel on a ship is vaporized into a cargo hold instead of inert gas, meanwhile, the method that a prime mover serves as a motor and is connected with shore power is adopted, the energy utilization efficiency of the prime mover is improved, and then the efficiency of the whole unloading device is improved; the problem that the heat efficiency is low due to the fact that a steam turbine is adopted by a prime motor is solved; in addition, waste gas is not generated in the crude oil conveying process of the unloading port, the port environment is not polluted, the development concepts of green ports and green ships are met, and therefore the system has excellent practical application value and economic benefits.
本发明提出了一种氨动力超级油轮货舱卸货及替代惰气供给系统,本系统包括氨燃料供给系统、氨气燃用系统、卸货及气体供给系统三个子系统,当超级油轮在卸货港口通过卸货泵从货舱向岸基油库输送原油时,本发明采用卸货及气体供给系统,该系统能够将船舶上氨燃料汽化后的氨气替代惰性气体通入货舱中,同时采用原动机为电动机并接岸电的这种方法,提高了原动机的能量利用效率,进而提高了整个卸货装置的效率,解决了原动机采用蒸汽透平这种方式的热效率低的问题;另外本系统在卸货港口输送原油过程中不产生废气,进而不会污染港口环境,符合绿色港口、绿色船舶的发展理念,因此,本系统具有极好的实际应用价值和经济效益。
