Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.
[0025] Such as figure 1 As shown, a full-immersion compressed hydrogen transportation system includes a hydrogen tank 1, the hydrogen tank 1 is arranged in an integrated box 2, and a liquid medium 10 is filled between the hydrogen tank 1 and the integrated box 2, so The liquid medium 10 is water.
[0026] The top of the integrated box 2 is provided with a gas storage room 7 for short-term storage of leaked hydrogen. The top of the gas storage room 7 is transparent for observing the leakage of the hydrogen tank 1 .
[0027] The gas storage room 7 is provided with an exhaust valve 5 for discharging the hydrogen to the outside to ensure the safe release of the hydrogen.
[0028] An underwater image monitoring device 8 is installed...

The invention discloses a full-immersion type compressed hydrogen transportation system which comprises a hydrogen tank. The hydrogen tank is arranged in an integrated box body, the space between thehydrogen tank and the integrated box body is filled with a liquid medium, and the liquid medium is water; a gas storage chamber is arranged at the top of the integrated box body, and an exhaust valveis arranged on the gas storage chamber and used for exhausting hydrogen outdoors; underwater image monitoring equipment is arranged at the position, higher than the hydrogen tank, of the inner side wall of the integrated box body and used for monitoring a gas signal in the integrated box body; and a water supplementing valve is arranged at the top of the integrated box body, and a water leakage valve is arranged at the bottom of the integrated box body. According to the full-immersion type compressed hydrogen transportation system, all hydrogen-containing devices are arranged underwater, air and harmful static electricity and open fire are isolated, so that the safety of a long-tube trailer in the transportation process is greatly improved; and meanwhile, a container type integrated transportation mode is adopted, so that directly transferring to ships and railways is suitable, and the possibility of realizing a mobile safe hydrogen refueling station is realized.
Description
technical field [0001] The invention belongs to the application field of clean energy, and more specifically relates to a full-immersion compressed hydrogen transportation system. Background technique [0002] At present, the main transportation methods for large-scale commercial application of hydrogen in the market include: long-tube trailer transportation, liquid hydrogen tank truck transportation and pipeline transportation. There are safety issues in the above three modes of transportation: [0003] For long tube trailers, the main hazard feature is a high pressure explosion. In terms of transportation pressure, the transportation pressure of long-tube trailers generally does not exceed 20MPa, and they are all equipped with pressure relief valves to fully ensure the safety of transportation. In addition, many cities stipulate that hydrogen transportation can only be carried at night when the temperature is greater than 30°C, which reduces the danger of long-tube trail...
