Claim 10:
11. A method for treating flue gas containing macromolecular colloids by using the gas adsorption and separation apparatus according to claim 1, comprising the following conditions and steps:
A: a flue gas treatment apparatus used comprises an adsorption bed for treating gas and a regeneration apparatus for regenerating an adsorbent, the adsorption bed is divided into a plurality of adsorption sections along a path through which the flue gas passes, the adsorption sections are communicated in sequence and are capable of being transferred or converted between the adsorption bed and the regeneration apparatus in sequence, the adsorption section at a flue gas inlet is an initial section, the adsorption section at a flue gas outlet is a final section, a flue gas inlet end of the adsorption bed is an initial end, and a flue gas outlet end of the adsorption bed is a final end;
B: the flue gas containing the macromolecular colloids continuously passes through the adsorption bed, and is discharged from the flue gas treatment apparatus after the adsorption purification process is completed;
C: when an adsorbent surface of the initial section is covered by the macromolecular colloids to a certain extent, the adsorption section is detached from the adsorption apparatus and transferred to the regeneration apparatus for desorption treatment, and a new or regenerated adsorption section is supplemented at the final end of the adsorption bed;
D: the adsorption section that has completed adsorption and been transferred to the desorption apparatus is subjected to a conventional desorption temperature treatment, and carbonization regeneration and ashing regeneration are superimposed at a desired frequency on the basis of the conventional desorption temperature treatment; and
E: the adsorption section that has completed the above regeneration treatment re-enters the adsorption bed.
