The invention discloses a diffusing system for an LNG storage tank of an LNG power-driven ship. The diffusing system comprises a first safety valve, wherein the first safety valve is mounted at the top of the LNG storage tank; one end of the exhaust pipe is connected with the first safety valve, the other end of the exhaust pipe extends in the direction away from the LNG storage tank, and the taper of the exhaust pipe is 1: 5-10. A plurality of jet holes are distributed in the side surface, close to the top end, of the bleeder; the second safety valve is mounted on the bleeder; the combustible gas alarm is used for detecting whether natural gas leaks or is diffused or not, and if yes, an alarm is given out; the condensation pipe extends downwards corresponding to the diffusion pipe, and a discharge valve is mounted at the bottom end of the condensation pipe; the liquid level alarm is mounted on the condensation pipe, is used for monitoring the liquid level height of the condensation pipe and is electrically connected with the discharge valve; the diffusing piece is mounted at the top end of the diffusing pipe and covers the multiple spraying holes, and at least one diffusing opening is formed in the side face of the diffusing piece; the controller is electrically connected with the combustible gas alarm, the liquid level alarm and the discharge valve; and the exhaust pipe, the bleeder and the condenser pipe are connected with one another.

    本发明公开了一种LNG动力船LNG储罐放散系统,包括第一安全阀安装于LNG储罐的顶部;排气管的一端与第一安全阀连接,另一端向远离LNG储罐方向延伸,排气管的锥度为1∶5~10;放散管竖直安装,靠近顶端的侧面分布有多个喷射孔;第二安全阀安装于放散管;可燃气体报警器用于检测是否有天然气泄露或者放散,若有,则发出警报;冷凝管对应于放散管向下延伸安装,在其底端安装有放泄阀;液位报警器安装于冷凝管,用于监测冷凝管的液位高度,与放泄阀电连接;放散件安装于放散管的顶端,遮盖多个喷射孔,在其侧面开设有至少一个放散口;控制器与可燃气体报警器、液位报警器、放泄阀均电连接;排气管、放散管、冷凝管相互连接。
