Description

Technical Field

[0001] The utility model relates to the technical field of argon recovery, in particular to an argon recovery pipeline component. Background Art

[0002] Argon is a colorless, odorless, tasteless rare gas. It is the third most common gas in the Earth's atmosphere, accounting for about 0.93%. The chemical symbol of argon is Ar, and its atomic number is 18. Argon is relatively stable and will not react with other elements at room temperature. The argon recovery pipeline assembly is a mechanism used to recover argon.

[0003] If argon is used as a protective gas or process gas, it may be contaminated during use, including impurities, dust or other harmful substances. When the recovery pipeline assembly recovers the argon, the filtration structure is generally installed inside the recovery pipeline assembly.
