Description
Technical Field
The invention relates to the technical field of gas storage tanks, in particular to a leakage detection and explosion-proof heat preservation device for an ultralow-temperature liquefied gas storage tank.
Background
The large-sized tank body is formed by welding a plurality of steel plates, and due to the limitation of welding technology, a welding seam between the two steel plates is likely to generate micro cracks. When the tank body is used for transporting or storing ultralow-temperature liquefied gas in a certain high-pressure state, such as liquid hydrogen, liquid nitrogen, liquefied natural gas and the like, the micropores can be enlarged under the action of ultralow temperature, so that the ultralow-temperature liquid overflows and leaks or evaporates.
In order to ensure the normal storage or transportation of the ultralow-temperature liquefied gas, a heat insulation structure is required to be arranged on the outer side of the tank body to reduce the leakage amount and the evaporation amount of the ultralow-temperature liquefied gas, and if the leaked gas cannot be discharged in time, the heat insulation structure on the outer side is likely to deform or even explode under the action of the leaked gas, so that unnecessary personal injury and property loss are caused.
