The invention provides a marine spraying system which is used for preventing sparks generated by welding of a loading cargo hold from damaging a liquid cargo hold. The loading cargo hold comprises a lower ship body and an upper ship body welded on the lower ship body; the lower ship body and the upper ship body are matched to define an inner space used for containing a liquid cargo tank. The marine spraying system comprises a water inlet main pipe and a spraying pipe arranged on the upper portion of the liquid cargo tank in a sleeving mode. The water inlet main pipe is used for communicating a cooling water source with the spraying pipe, a main on-off control valve is arranged on the water inlet main pipe, and the control mode of the main on-off control valve comprises manual control; a plurality of spraying heads facing the bulkhead of the liquid cargo tank are distributed on the spraying pipe; water mist sprayed by the multiple spraying heads is matched to form a cooling mist curtain covering the wall of the liquid cargo tank in the circumferential direction, the cooling mist curtain is used for extinguishing sparks flying to the wall of the liquid cargo tank, the integrity of the liquid cargo tank in the building process of the loading cargo tank is effectively guaranteed, and potential safety hazards caused by smoldering of an external heat insulation layer of the liquid cargo tank are avoided.
本发明提供一种船用喷淋系统,用于防止装载货舱焊接产生的火花损坏液货舱;装载货舱包括下部船体和焊接在下部船体上的上部船体;下部船体与上部船体配合围成用于容置液货舱的内部空间;船用喷淋系统包括进水主管和套设在液货舱上部的喷淋管;进水主管用于连通冷却水源和喷淋管,且进水主管上设有主通断控制阀,主通断控制阀的控制方式包括手动控制;喷淋管上分布有若干个朝向液货舱舱壁的喷淋头;若干个喷淋头喷出的水雾配合形成周向覆盖液货舱舱壁的冷却雾帘,用于熄灭飞向液货舱舱壁的火花,有效保证装载货舱搭建过程中液货舱的完整性,避免液化舱外部隔热层阴燃引发安全隐患。
