The invention relates to the field of ship liquid hydrogen transportation, and discloses a device for reducing the evaporation rate of a ship liquid hydrogen cabin. The device is arranged based on a liquid hydrogen cabin and an LNG tank and comprises a cooling coil arranged outside the liquid hydrogen cabin, an inlet of the cooling coil is communicated with the liquid hydrogen cabin and the LNG tank, and an outlet of the cooling coil is communicated with the LNG tank and the outside of the device; hydrogen evaporation gas enters a cooling coil from a liquid hydrogen cabin to cool the liquid hydrogen cabin, and then flows out of the device; according to the second cooling channel, LNG evaporation gas enters the cooling coil from the LNG tank to cool the liquid hydrogen cabin and then flows out of the device or flows back to the LNG tank. According to the third cooling channel, LNG liquid enters the cooling coil from the LNG tank to cool the liquid hydrogen cabin, and then the liquid hydrogen cabin flows out of the outflow device or flows back into the LNG tank. According to the device, the cargo evaporation rate in the liquid hydrogen cabin is effectively reduced, hydrogen evaporation gas and LNG cold energy are fully utilized, and the transportation cost and the fuel cost of the liquid hydrogen transport ship are greatly reduced.

    本申请涉及船舶液氢运输领域,公开了一种降低船舶液氢舱蒸发率的装置。该装置是基于液氢舱和LNG罐设置的,包括设置在液氢舱外的冷却盘管,冷却盘管的进口与液氢舱和LNG罐连通,冷却盘管的出口与LNG罐和装置外部连通;该装置包括降温通路一:氢蒸发气从液氢舱进入冷却盘管对液氢舱降温,然后流出装置外部;降温通路二:LNG蒸发气从LNG罐进入冷却盘管对液氢舱降温,然后流出装置外部或回流至LNG罐;降温通路三:LNG液体从LNG罐进入冷却盘管对液氢舱降温,然后从流出装置外部或回流至LNG罐内。本申请的装置有效降低了液氢舱内货物蒸发率,充分利用氢蒸发气及LNG冷能,大大降低了液氢运输船的运输成本及燃料成本。
