The invention discloses a nitrogen oxide emission reduction system and a ship. The nitrogen oxide emission reduction system comprises a fuel supply cabin, a fuel water adding cabin and a fuel injection device, wherein the fuel supply cabin and the fuel water adding cabin are both connected with the fuel injection device, the fuel injection device is connected with a main engine, the fuel supply cabin supplies fuel oil to the fuel injection device, the fuel water adding cabin supplies fresh water to the fuel injection device, and the fuel oil and the fresh water are treated in the fuel injection device and then injected into the main engine. According to the nitrogen oxide emission reduction system, a certain amount of fresh water is added into fuel by arranging the fuel water adding cabinand the fuel injection device so that the reaction temperature in the main engine can be reduced, the generation of nitrogen oxide is reduced, a ship meets the requirements of related waste gas emission standards, compared with a mode of treating waste gas by adopting a selective catalytic reduction method, the occupied space is small, the arrangement is convenient, and the cost is also greatly reduced.

    本发明公开一种氮氧化物减排系统及船舶,氮氧化物减排系统包括燃料供应舱、燃料加水舱和燃料注入装置,燃料供应舱和燃料加水舱均与燃料注入装置连接,燃料注入装置与主机连接,燃料供应舱向燃料注入装置供应燃油,燃料加水舱向燃料注入装置供应淡水,燃油和淡水在燃料注入装置中经处理后注入主机。本发明的氮氧化物减排系统通过设置燃料加水舱和燃料注入装置在燃料中添加一定量的淡水,能够降低主机内的反应温度,从而减少氮氧化物的生成,使船舶满足相关废气排放标准的要求,相较于采用选择性催化还原法对废气进行处理的方式,不仅占用较少的空间,方便布置,成本也大大降低。
