Technical Field

[0001] The utility model belongs to the technical field of distillation equipment, in particular to a common extraction device for high-purity oxygen and krypton-poor xenon. Background Art

[0002] The extraction of high-purity oxygen and krypton-depleted xenon usually requires a complete system to carry out the extraction work, which usually includes adsorption, cooling, catalysis, heat exchange, distillation and other processes.

[0003] In the prior art, distillation is a physical process, which usually refers to a liquid mixture being heated to boiling, then cooled and condensed into a liquid. A distillation tower is usually the last step in the extraction of high-purity oxygen and krypton-depleted xenon.

The exhaust pipe 11 can be effectively preheated by the arrangement of the electric heating tube 14, thereby effectively reducing the condensation of steam after it is discharged into the exhaust pipe 11 due to the high temperature of the steam discharged from the distillation tower body 1 during exhaust work and the low temperature of the exhaust pipe 11 itself, which then causes excess impurities to adhere to the inner wall of the exhaust pipe 11, resulting in a decrease in the service life of the exhaust pipe 11. The overall stability of the device is effectively improved.

At this time, the vibration of the vibration motor 41 will be transmitted to the exhaust pipe 11 through the first fixed block 4, so as to achieve the purpose of shaking off the impurities attached to the side wall of the exhaust pipe 11. When the impurities attached to the inner wall of the exhaust pipe 11 fall into the interior of the distillation tower body 1, the collecting plate 51 will automatically catch the impurities to prevent the impurities from falling into the interior of the distillation tower body 1. When the scraper 28 is scraping, the first baffle 6 can automatically play a partition function to prevent the upper impurities scraped by the scraper 28 from falling into the bottom of the first discharge pipe 2. At the same time, the second baffle 61 will automatically strengthen the partition function to reduce the impurities from falling from both sides of the fixed frame 26 to the bottom.
