A zero-ammonia-residue ship liquid ammonia supply and removal method comprises the following steps: firstly, purging a liquid ammonia supply system and the interior of a main engine by using 30barg high-pressure nitrogen to remove most ammonia fuel; the residual ammonia is further absorbed by using fresh water, the fresh water after absorbing the ammonia is completely blown away by using 30 barg of high-pressure nitrogen, and finally, the liquid ammonia supply system and the interior of the main machine are forcibly evaporated and blown by using 5 barg of heated low-pressure nitrogen, so that the effect of zero ammonia residue is finally achieved. After the device is used for removing the interiors of a liquid ammonia supply system and a main engine, zero ammonia residue can be realized, the removing effect is good, the safety of related systems and personnel on a ship can be guaranteed, the whole ammonia removing process is automatically executed after the main engine runs in an ammonia fuel mode, automatic treatment of ammonia can be realized, personnel operation is not needed, the automation degree is high, and the working efficiency is high. The operation is reliable.
一种零氨残留的船舶液氨供给清除方法,首先使用30barg的高压氮气对液氨供给系统及主机内部进行吹扫,清除大部分的氨燃料。使用淡水对残留的氨进一步吸收处理,再次使用30barg的高压氮气,将吸收氨后的淡水吹除干净,最后使用5barg的加热低压氮气,对液氨供给系统及主机内部进行强制蒸发及吹扫处理,最终达到零氨残留的效果。使用本发明对液氨供给系统及主机内部清除处理后,可实现氨的零残留,清除效果好,可保障船上相关系统以及人员的安全,在主机氨燃料模式运行结束后,整个氨的清除流程自动执行,并可实现氨的自动处理,无需人员操作自动化程度高,运行可靠。
