The invention provides a leakage liquid storage device of an independent liquid tank, which is characterized in that a thermal insulation layer is arranged on the outer wall of the liquid tank, a leakage channel is reserved between the liquid tank and the thermal insulation layer. A flow guide pipe penetrates through the thermal insulation layer at the bottom of the liquid tank, the upper end of the flow guide pipe is communicated with the leakage channel, the lower end of the flow guide pipe is communicated with a release valve, and a liquid storage container is arranged below the release valve. The liquid storage container is divided into an upper half part and a lower half part, the lower half part is arranged at the bottom of the ship body, the upper half part and the lower half part are detachably connected, the upper half part comprises an opening formed in the top, and the release valve is located in the opening. The device has the beneficial effects that the structure is simple, the universality is high, the device can be widely applied to liquefied gas ships or dual-fuel power ships for carrying low-temperature liquid goods such as LPG, LEG and LNG, leaked liquid can be temporarily stored on the basis that the structural strength of the ship body is not affected, and the cost is low.
本发明提供了一种独立液舱的泄漏液体储存装置,在液舱的外壁设有保温层,且液舱和保温层之间留有泄漏通道,在液舱底部的保温层中穿设有导流管,导流管的上端与泄漏通道相连通,下端连通有泄放阀,泄放阀的下方设有储液容器,储液容器分为上下两半部分,下半部分设置在船体的底部,上半部分与下半部分之间可拆卸连接,上半部分包括开设在顶部的开口,泄放阀位于开口之中。本发明的有益之处在于,结构简单,通用性强,可以广泛应用在运载LPG、LEG、LNG等低温液货的液化气体船或双燃料动力船上,并能够在不影响船体结构强度的基础上临时存储泄漏液体,成本较低。
