The invention provides a ventilation system of an LNG (Liquefied Natural Gas) ship. The ventilation system of the LNG ship comprises an LNG tank, an air supply pipe, a ventilation pipeline and a ventilation mast, the LNG tank is arranged in the closed space of the ship body; the air supply pipe is used for feeding external air into the closed space through an air feeder; one end of the ventilation pipeline is communicated with the closed space, and the other end of the ventilation pipeline is located above the ship body; and the ventilation mast is arranged at the top of the ventilation pipeline. Air in the closed air is directly conveyed to the ventilation mast on the top through the ventilation pipeline, and the technical problems that in the prior art, pipeline arrangement is not reasonable, and the occupied space is large are solved.

    本发明提供了一种LNG船的透气系统,所述LNG船的透气系统包括LNG罐、送风管、透气管道、透气桅;所述LNG罐设置在船体的密闭空间内;所述送风管通过送风机将外部空气送入所述密闭空间;所述透气管道一端与所述密闭空间连通,所述透气管道的另一端位于所述船体上方;所述透气桅设置在所述透气管道顶部。通过透气管道直接将所述密闭空气的中气体送上顶部的所述透气桅,有助于解决现有技术中管路布置不合理,占用空间较大的技术问题。
