The invention provides a device for air replacement of a ship cargo hold, which comprises a gas transmission system and a gas transmission pipeline, the gas transmission pipeline is enclosed by a first wall plate, a second wall plate, a third wall plate and a transverse bulkhead of the cargo hold which are sequentially connected, one end of the gas transmission pipeline is communicated with the gas transmission system, and the other end of the gas transmission pipeline is communicated with the cargo hold, so that gas enters the cargo hold through the gas transmission pipeline. According to the device for air replacement of the ship cargo hold, the gas conveying pipeline is built by attaching to the transverse hold wall of the cargo hold, then the gas conveying system is used for completing air inerting and replacement of the front cargo hold area and the rear cargo hold area of the transverse hold wall, and the requirements for ventilation and air inerting are met under the condition that the arrangement space of a liquefied gas ship is limited; and the transverse bulkhead of the main bearing structure is further reinforced, so that the function integration of the ship structure is realized, the cost is saved, and the air replacement efficiency and the safety are improved.

    本发明提供一种用于船舶货舱空气置换的装置,包括输气系统和输气管道,输气管道由依次连接的第一壁板、第二壁板、第三壁板及货舱的横舱壁围成,输气管道一端与输气系统连通,另一端与货舱连通,使气体经由输气管道进入货舱。本发明提供的用于船舶货舱空气置换的装置,依附货舱的横舱壁建造输气管道,再利用输气系统完成横舱壁前后两个货舱区域的空气惰化和置换,在液化气船布置空间紧张的情况下既满足了通风和空气惰化的需求,又对主要承力结构的横舱壁进一步加强,实现船舶结构功能一体化,节省了成本,提高了空气置换效率以及安全性。
