According to the ammonia fuel and cargo combined storage cabin of the CO2 transport ship, a fuel cabin and a cargo cabin of the ammonia-powered CO2 transport ship are ingeniously combined, a CO2 storage tank is immersed in liquid ammonia fuel, the temperature difference between liquid carbon dioxide and the external environment is reduced through cold energy of the liquid ammonia fuel, and the evaporation rate of carbon dioxide BOG is reduced; and when the CO2 transport ship returns to a loading port, the temperature of the CO2 storage tank is low, and the CO2 storage tank does not need to be pre-cooled when carbon dioxide is refilled. Besides, the combined storage cabin is used for storing liquid ammonia fuel and liquid carbon dioxide at the same time, a ship does not need to be independently provided with a large fuel cabin, the utilization rate of the cargo cabin space of the ship is increased, and the technical problem of storage of the liquid ammonia fuel on the ship is solved. And meanwhile, the cargo capacity of the liquid carbon dioxide is greatly increased, the operation benefits of the ship are improved, and good economical efficiency is achieved.
本发明提出了一种CO2运输船氨燃料与货物的组合储存舱,巧妙的将氨动力CO2运输船的燃料舱与货舱结合,使CO2储罐浸没在液氨燃料中,利用液氨燃料的冷能降低了液态二氧化碳与外界环境的温差,降低二氧化碳BOG的蒸发率;并且CO2运输船返回装货港时,CO2储罐的温度较低,在重新加注二氧化碳时CO2储罐无须进行预冷操作。另外,本发明利用组合储存舱同时储存液氨燃料和液态二氧化碳,船舶无需单独设置较大的燃料舱,提高了船舶货舱空间的利用率,解决了液氨燃料在船舶上储存的技术难题;同时大大增加了液态二氧化碳的载货量,提高了船舶的营运效益,具有良好的经济性。
