Problems solved by technology
If a fire or other accident occurs in the liquid hydrogen system, the low-temperature liquid hydrogen will quickly gasify at ambient temperature, and the hydrogen concentration will reunite within the accident range. At this time, an explosion will easily occur after encountering an open flame, and the hazard is extremely serious.

The invention discloses a safety protection device for a hydrogen liquefaction system and belongs to the technical field of hydrogen liquefaction. Comprising a liquid hydrogen storage tank (1), a liquid hydrogen discharge outlet pipeline (2), a special quick connector (3), an unqualified liquid hydrogen stop valve (4), an unqualified liquid hydrogen pipeline (5), a first accident vaporizer front end stop valve (6), a second accident vaporizer front end stop valve (7), a first accident vaporizer (8), a second accident vaporizer (9), a first accident vaporizer rear end stop valve (10) and a second accident vaporizer rear end stop valve (11). The device comprises an emergency vaporizer outlet pipeline (12), an emergency heater (13), an emergency heater outlet pipeline (14), a torch system (15) and the like. The device has the advantages that safe and stable operation of a hydrogen liquefaction system can be ensured, and liquid hydrogen components with unqualified purity in the system and gas-liquid mixed components diffused under overpressure of the liquid hydrogen storage tank body can be collected, gasified and incinerated; and in an accident state, a large amount of liquid hydrogen can be quickly gasified and conveyed to a torch system to be safely incinerated, discharged and the like.
Description
technical field [0001] The invention belongs to the technical field of hydrogen liquefaction, and in particular relates to a safety protection device for a hydrogen liquefaction system, which is suitable for liquid hydrogen components with unqualified purity, gas-liquid mixed components in the discharge port of a liquid hydrogen storage tank, and hydrogen liquefaction system accident conditions safe discharge. Background technique [0002] Driven by the dual goals of "carbon peaking and carbon neutrality", the development of hydrogen energy industry has become a hot spot in my country's industrial development, and hydrogen energy is in a critical period of vigorous development. Hydrogen energy is regarded as the most potential secondary energy in the 21st century, and the development and utilization of hydrogen energy has become an important direction for a new round of world energy transformation. Since the beginning of this century, western developed countries led by the ...
