AI Technical Summary

Technical Problem

Traditional adsorption towers are prone to adsorbent pulverization and wear in high-pressure gas flow, leading to gas flow short circuits and localized flow deviations, which cannot meet the industrial sector's demand for improved gas cleanliness.

Method used

The device employs a tube-in-tube structure with the outer and inner tubes coaxially arranged. The inner tube is divided into an air inlet section, an adsorption section, and a dust removal section. Combined with an elastic compensation mechanism and a filter layer design, it achieves multi-stage purification and uniform distribution of gas, and improves adsorption efficiency and equipment stability through a countercurrent regeneration mechanism.

Benefits of technology

It significantly improves adsorption efficiency, ensures long-term stability of output gas, extends the service life of adsorbent, reduces gas resistance, simplifies system structure, and improves self-cleaning capability.

Abstract

The invention relates to an adsorption tower and a gas nano purifier. The adsorption tower comprises an outer pipe body and an inner pipe body coaxially arranged in the outer pipe body; a first air outlet is formed in the pipe wall of the outer pipe body; the inner pipe body comprises a gas inlet section, an adsorption section and a dust removal section which are sequentially communicated from bottom to top; an air inlet is formed in the pipe wall of the air inlet section; the adsorption section is filled with an adsorbent, and a first filter screen and a second filter screen are arranged at the joint of the adsorption section and the air inlet section and the joint of the adsorption section and the dust removal section respectively; a filter layer is arranged on at least part of the side wall of the dust removal section; under the purification working condition, high-pressure gas to be treated enters the inner pipe body from the gas inlet, sequentially upwards penetrates through the adsorption section and the dust removal section, enters the annular gap between the inner pipe body and the outer pipe body through the filter layer, and then is discharged from the first gas outlet. Through the arrangement, a pipe-in-pipe structure in which the outer pipe body and the inner pipe body are coaxially arranged is adopted, so that the integration level of equipment is improved, the size is reduced, and multi-stage purification of diffusion, deep adsorption and precise dust removal of gas in a single component is realized.
