This invention relates to an adsorption tower and a gas nano-purifier. The adsorption tower includes an outer tube and an inner tube coaxially arranged within the outer tube. The outer tube has a first outlet on its wall. The inner tube includes an inlet section, an adsorption section, and a dust removal section connected sequentially from bottom to top. The inlet section has an inlet on its wall. The adsorption section is filled with adsorbent, and a first filter and a second filter are respectively provided at the connection points between the adsorption section and the inlet and dust removal sections. At least a portion of the sidewalls of the dust removal section is configured as a filter layer. Under purification conditions, the high-pressure gas to be treated enters the inner tube through the inlet, passes sequentially upwards through the adsorption and dust removal sections, enters the annular gap between the inner and outer tubes via the filter layer, and is discharged from the first outlet. Through this configuration, using a tube-in-tube structure with the outer and inner tubes coaxially arranged, the integration of the equipment is improved and its volume is reduced, achieving multi-stage purification of gas within a single component, including diffusion, deep adsorption, and precision dust removal.
