The gas pump, the pressure sensor installed on the low temperature adiabatic container and the temperature sensor installed at the outlet end of the vaporizer are connected, and the invention can quickly and safely pressurize the low temperature heat insulation container in a short time.

Description

technical field [0001] The invention belongs to the technical field of low-temperature heat-insulating containers, and in particular relates to an intelligent supercharging device and a supercharging method for low-temperature heat-insulating containers. Background technique [0002] Low-temperature heat-insulated containers have been widely used in industrial production due to their convenience, safety, and refillable characteristics. Cryogenic insulated gas cylinders usually have a double-layer structure including an inner tank and an outer shell. In order to reduce radiation heat transfer, the inner tank needs to be covered with an insulating layer. Cryogenic insulation containers require the container pressure to be maintained at a relatively high constant value to ensure stable liquid supply. However, many existing LNG filling devices for automobiles in China can only provide low-saturated LNG liquid, which cannot guarantee the pressure value and stability of the gas c...

AI Technical Summary

Problems solved by technology

However, many existing LNG filling devices for automobiles in China can only provide low-saturated LNG liquid, which cannot guarantee the pressure value and stability of the gas cylinder, resulting in insufficient liquid supply.

[0003] In order to solve the above problems, the existing low-temperature heat-insulated container uses a finned tube as a vaporizer, and uses the thermal energy of the air to vaporize the low-temperature liquid and fill it into the container to achieve pressurization. This pressurization method takes a long time to pressurize and cannot be realized in a short time. Rapid pressurization, and less and less effective pressurization as the liquid level in the cryogenically insulated vessel gets lower and lower

At the same time, since there is no overcurrent protection device on the booster pipeline, if the booster pipeline breaks, it cannot be cut off, which will pose a safety hazard
