The invention belongs to the technical field of cargo ships, and discloses an ammonia fuel ventilation mast and a dry bulk carrier, the ammonia fuel ventilation mast comprises a tower, a cantilever, an inhaul cable and a ventilation pipe, and the tower is vertically arranged and provided with a first channel; the cantilever is connected with the tower and forms an included angle with the tower, the end, away from the tower, of the cantilever inclines upwards, and the cantilever is provided with a second channel. Two ends of the inhaul cable are respectively connected with the top end of the tower and one end of the cantilever away from the tower; the vent pipe sequentially penetrates through the first channel and the second channel, and one end of the vent pipe penetrates out of the second channel to form an outlet. The tower is mounted at the tail section of the ship body, and the cantilever extends towards the outer side of the ship body, so that the outlet of the vent pipe at the end part of the cantilever can be far away from the tail part of the ship body, the toxic area of ammonia is partially transferred to the outside of the ship tail, the requirement of laws and regulations on a 25m spacing distance is met, and the application of ammonia fuel on small and medium-sized dry bulk cargo ships is realized.
本发明属于货船技术领域,公开了一种氨燃料透气桅及干散货船,氨燃料透气桅包括塔架、悬臂、拉索和透气管,塔架竖直布置并设有第一通道;悬臂与塔架连接并与塔架呈夹角布置,且悬臂远离塔架的一端朝上倾斜,悬臂设有第二通道;拉索两端分别与塔架的顶端和悬臂远离塔架的一端连接;透气管依次穿设于第一通道和第二通道,透气管一端穿出第二通道并形成出口。将塔架安装于船体尾段且将悬臂朝船体外侧延伸设置,使得悬臂端部的透气管的出口可以远离船体尾部,从而将氨的毒性区域部分地向船尾外部转移,满足法规对25m间隔距离的要求,实现氨燃料在中小型干散货船上的应用。
