1. selective removal and reclaim the method for sulfur dioxide from the emission gases that contains sulfur dioxide, described method comprises:

  • Described emission gases is contacted in the sulfur dioxide absorption tower with the moisture buffering absorption liquid that comprises natrium malicum, thereby sulfur dioxide is absorbed from described emission gases to described absorption liquid, and the waste gas of sulfur dioxide and the absorption liquid of enrichment sulfur dioxide are therefrom removed in generation;

    The absorption liquid that heats described enrichment sulfur dioxide in the sulfur dioxide stripper is with desorb sulfur dioxide, thus the stripper gas of generation regeneration sulfur dioxide absorption liquid and enrichment sulfur dioxide;

    AndDescribed regeneration sulfur dioxide absorption liquid is incorporated in the described sulfur dioxide absorption tower again.
