The invention relates to the technical field of ships, and discloses a double-wall pipe ventilation system and a ship. The double-wall pipe ventilation system is used for ventilating an annular space between the inner wall pipe and the outer wall pipe of a double-wall pipe, the annular space is provided with a ventilation inlet and a ventilation outlet, methanol circulates in the inner wall pipe of the double-wall pipe, the double-wall pipe ventilation system comprises a pipeline, one end of the pipeline is provided with an air inlet, and the other end of the pipeline is provided with a fan. The ventilation inlet is communicated with the air inlet, the ventilation outlet is communicated with the fan, and the fan is arranged at the top of the methanol pump cabin; the double-wall pipe is arranged in the cabin, the air inlet is arranged close to the ventilation inlet and the ventilation outlet, and the pipeline is arranged on the upper building front wall and the deck A and communicated to the fan. The fan is arranged at the top of the methanol pump cabin so that on one hand, continuous ventilation of the annular space is guaranteed; on one hand, seawater can be prevented from entering the air inlet, the fan is convenient to maintain, when methyl alcohol in the inner wall pipe of the double-wall pipe leaks, the methyl alcohol can be found and treated in time, and the safety of a ship is guaranteed.
本发明涉及船舶技术领域,公开一种双壁管通风系统及船舶。其中双壁管通风系统以对双壁管内外壁管之间的环形空间进行通风,环形空间设置有通气进口和通气出口,双壁管的内壁管内流通有甲醇,双壁管通风系统包括管路,管路的一端设置有空气进口,另一端设置有风机,通风进口连通于空气进口,通气出口连通于风机,风机设置于甲醇泵舱的顶部;双壁管设置于机舱,空气进口靠近通风进口和通风出口设置,管路布设于上建前壁和A甲板并连通至风机。本发明风机设置在甲醇泵舱的顶部,一方面保证对环形空间进行持续的通风;一方面能防止海水进入空气进口,便于风机的维修,在双壁管内壁管的甲醇发生泄漏时,也能及时的发现和处理,有利于保证船舶的安全性。
