The invention discloses a cluster type ventilation mast and a liquefied gas ship applying the cluster type ventilation mast. The cluster type ventilation mast comprises a combined base, an ascending pipe and a ventilation cap installed at the top of the ascending pipe. The combined base is installed in an open-air area of a ship, a heating coil is arranged in the combined base, a steam pipeline isinstalled at an inlet of the heating coil, and the steam pipeline is connected with a steam system of the ship; a ventilation pipe is arranged above the combined base; the multiple ascending pipes are installed at the top of the combined base and communicate with the safety valve discharging pipelines of the corresponding liquid cargo tanks. According to the cluster type ventilation mast, the ascension pipe is arranged to be cluster-shaped, so that the area of a dangerous area formed at the outlet of the ventilation mast can be greatly reduced, the arrangement limitation of a ventilation system is reduced, the use of explosion-proof equipment and outfitting pieces is reduced, and the arrangement of the ventilation system of the safety valve of the liquid cargo tank is more flexible.

    本发明公开了一种集束式透气桅及应用该集束式透气桅的液化气体船舶,所述集束式透气桅包括组合基座、上升管以及安装在上升管顶部的透气帽;组合基座安装在船舶的露天区域上,组合基座的内部设置有加热盘管,加热盘管进口安装有蒸汽管路,蒸汽管路与船舶的蒸汽系统相连;组合基座的上方安装透气管;所述上升管设置有多个,多个上升管安装在组合基座的顶部且与相应液货舱的安全阀排出管路相连通。本发明通过将上升管设置成集束状,可大大缩小透气桅出口形成的危险区域的面积,降低了通风系统的布置限制,减少了防爆设备及舾装件的使用,使得液货舱安全阀透气系统的布置更为灵活。
