Description

Technical Field

[0001] The utility model relates to the technical field of liquid argon stations, in particular to an environmentally friendly and energy-saving liquid argon station. Background Art

[0002] There are various types of liquid argon stations for producing high-purity argon gas, such as cryogenic liquid pump type liquid argon stations, liquid nitrogen cryogenic pump type liquid argon stations, liquid nitrogen vaporization type liquid argon stations, pneumatic type liquid argon stations, and electronic type liquid argon stations, etc. The main method is to extract and process liquid argon through various equipment to obtain high-purity argon gas.

[0003] For example, in a cryogenic liquid pump type liquid argon station, this type of liquid argon station uses a cryogenic liquid pump as the main gas extraction equipment. Through the operation of the cryogenic liquid pump, liquid argon is pumped out from the liquid argon tank, and then after being processed by a vaporizer, high-purity argon gas is finally obtained.

[0004] However, liquid argon stations need to consume a large amount of energy to maintain their operation, and when liquid argon is vaporized through an air-cooled vaporizer, water vapor in the external air is likely to condense on the surface of the air-cooled vaporizer. If not cleaned in time, it is likely to affect the vaporization efficiency.

[0005] Based on this, the utility model designs an environmentally friendly and energy-saving liquid argon station to solve the above problems. Summary of the Utility Model

The dry gas after moisture condensation flows through the defrosting component 32 for heating treatment and then flows to the other group of gasification components 31, so as to melt and blow off the condensed frost on the other group of gasification components 31 through the dry hot air; after working for a period of time, the flow order of the external air passing through the two groups of gasification components 31 can be adjusted, so as to defrost the two groups of gasification components 31 in sequence; defrosting the other group of gasification components 31 with the dry air of a group of gasification components 31 enables defrosting to be carried out during the gasification process and saves energy consumption.

[0034] In some embodiments, as Figures 1-4 shown, as a preferred embodiment of the present utility model, the gasification component 31 includes a box body 311, an air temperature gasifier 312 and an air inlet component.

[0041] In this embodiment, when the gasification mechanism 3 and the argon filling mechanism 5 are working properly, the external air is driven by the fan 314 to enter a group of boxes 311 through the left air outlet 313. The external air exchanges heat with the air temperature vaporizer 312 in the box 311, and the moisture in the external air condenses on the surface of the air temperature vaporizer 312.
