Claim 0:
1. A gas adsorption and separation apparatus, comprising:
an adsorption functional module and a further functional module, wherein
a main functional portion of the adsorption functional module is an adsorption series composed of two or more adsorption units arranged in sequence,
the adsorption series comprises a head end and a tail end,
a gas to be separated passes through the adsorption series in a direction from the head end to the tail end,
when reaching a preset degree of saturation adsorption of the adsorbate gas, the adsorption unit located at the head end is detached from the adsorption series and enters the further functional module comprising a desorption apparatus and sequentially re-enters the adsorption series from the tail end after a further process treatment including a desorption treatment is completed,
each of h adsorption units is an adsorptive fixed bed composed of an adsorbent and a mechanical support structure,
the adsorption unit which has completed saturated adsorption is referred to as a saturated adsorption unit, and the adsorption unit which has completed desorption and regeneration is referred to as a regenerated adsorption unit, and
the adsorption-desorption mode used is temperature swing adsorption, a main functional portion of the desorption apparatus is a desorption series composed of two or more saturated adsorption units arranged in sequence, which comprises a saturation end and a regeneration end, a high-temperature desorption gas passes through the desorption series in a direction from the regeneration end to the saturation end to generate a concentrated adsorbate gas, and the saturated adsorption unit is detached from the desorption series after completing desorption and regeneration.
