The invention relates to the technical field of natural gas safe transportation, in particular to an LNG tank protection device and a dual-fuel container ship comprising the same, the LNG tank protection device is applied to a ship body, the LNG tank protection device comprises a frame arranged on the ship body, a containing space for containing a tank is formed in the frame, the tank is used for loading LNG, and a supporting frame for supporting the tank is arranged below the tank; the upper end face of the supporting frame is matched with the lower end face of the tank body, the supporting frame is arranged on a deck on a ship body, a plurality of ventilation openings communicated with the containing space are formed in the two side faces of the frame, a truss used for supporting is arranged on the top of the frame, an upper pipe opening is formed in the upper portion of the inner side wall of the frame, and a lower pipe opening communicated with the upper pipe opening is formed in the outer side wall of the frame. The upper pipe opening is higher than the lower pipe opening, and the upper pipe opening and the lower pipe opening are connected through an inclined pipe. The ventilation opening is communicated with the containing space to form a ventilation space, the insufficient ventilation quantity is avoided, the ventilation effect is improved, and in addition, the upper pipe opening is formed, so that the top natural gas concentration in the containing space is reduced.

    本发明涉及天然气安全运输技术领域,具体涉及一种LNG罐体保护装置及包括它的双燃料集装箱船,应用于船体上,包括设置在船体上的框架,框架内部具有容纳罐体的容纳空间,罐体用于装载LNG,罐体下设置有支撑其的支撑架,支撑架上端面与罐体下端面适配设置,支撑架设置在船体上的甲板上,框架两侧面均设置有多个与容纳空间连通的通风口,框架顶部设置有用于支撑的桁架,框架内侧壁的上部设置有上管口,框架外侧壁设置有与上管口连通的下管口,上管口的高度高于下管口的高度,上管口与下管口之间通过斜管连接。本发明通风口的设置使得其与容纳空间连通形成的通风空间,避免通风量不足,提高通风效果,此外上管口设置降低了容纳空间中顶部天然气浓度。
