Vertical-type low-temperature heat-insulation gas cylinder

Abstract

The invention relates to a vertical-type low-temperature heat-insulation gas cylinder which comprises a shell, a liner, a distributor, an in-cylinder pipeline of a pipeline control system, a neck pipe and an insulation layer; the shell comprises a shell body and a vacuumizing connector which is connected with the shell body in a sealed mode; the liner comprises a liner body and a coil pipe connector which is connected with the liner in a sealed mode and is positioned at the bottom of the liner body; the heat insulation layer is arranged on the outer wall of the liner body; the distributor is a steel integrated component which is provided with an internal channel; the liner is positioned in the inner cavity of the shell body; the distributor is fixed on the shell body in a sealed mode; the upper end of the neck pipe is fixed on the distributor in a sealed mode; the lower end of the neck pipe is arranged at the periphery of the liner body and is fixed on the liner body in a sealed mode, thus the liner body is suspended in the shell body; the in-cylinder pipeline of the pipeline control system comprises a supercharging coil pipe, a vaporization coil pipe and a seal plate assembly; and the seal plate assembly comprises an inner cavity first pipe, liquid inlet and outlet pipes, a gas discharging pipe and a seal plate. The vertical-type low-temperature heat-insulation gas cylinder provided by the invention has the advantages of good heat insulation effect, is convenient to use and is safe and reliable.

Description

technical field [0001] The invention relates to a container for holding and storing cryogenic liquid. Background technique [0002] At present, in machinery, chemical industry, medicine and other industries, a large amount of gases such as oxygen, argon and nitrogen are used. When preparing these gases, they are stored in high-pressure steel cylinders by high-pressure compression. Due to the small gas storage capacity of high-pressure steel cylinders, And filling and transportation are all comparatively inconvenient. Cryogenic insulating gas cylinders, also known as Dewar cylinders, can be used to store low-temperature liquids such as liquid nitrogen, liquid oxygen, and liquid natural gas (also known as low-temperature liquid gases). Due to the large gas storage capacity of cryogenic insulated gas cylinders, which are safe and reliable, the storage and transportation of liquid gases are more economical and convenient. [0003] The usual low-temperature insulated gas cylind...

AI Technical Summary

Problems solved by technology

Since the inner tank and outer shell of the cryogenic insulating gas cylinder cannot be completely insulated, and the temperature difference between the liquid gas in the bottle and the external environment is large, the evaporation rate of the existing cryogenic insulating gas cylinder is mostly above 2%.
