Description

Technical Field

[0001] The utility model relates to the technical field of liquid argon production, in particular to an argon refinement tower for liquid argon production. Background Art

[0002] The refined argon tower is one of the equipment used to separate and purify argon in air separation equipment. It usually adopts the method of distillation and utilizes the difference in boiling points between liquid argon and impurity gases to separate liquid argon from the mixture. The working principle of the refined argon tower is to send a mixture containing argon and impurity gases into the refined argon tower, and form a gas mixture in the tower by heating and evaporating the mixture. Then, the gas mixture is cooled to condense the liquid argon into droplets and flow downward through the small holes on the tower plate. The droplets meet the rising gas on the tower plate to transfer mass and heat, so that the impurity gas in the liquid argon is continuously evaporated, while the liquid argon is continuously condensed. Finally, the liquid argon is collected at the bottom of the tower, and the impurity gas is discharged from the top of the tower.

[0003] The prior art has the following problems:

[0004] 1. In the actual use process of the existing refined argon tower, a single heating rod is used to heat the liquid argon mixture. However, in the actual operation process, the existing heating method has a slow heating effect, thereby reducing the use efficiency of the refined argon tower;

[0005] 2. When the existing refined argon tower is in use, the refined argon tower is usually treated with anti-corrosion paint. However, as the service life of the refined argon tower is extended, the anti-corrosion paint will age. When the anti-corrosion paint ages and falls off, the anti-corrosion effect of the refined argon tower will be reduced, resulting in corrosion and rust on the outer surface of the refined argon tower. When the refined argon tower is corroded and rusted, the use intensity of the refined argon tower will be reduced. Therefore, a refined argon tower for liquid argon production is proposed.
