Title:
DIRECT AIR CAPTURE CARBON DIOXIDE ENERGY SAVING SYSTEM AND METHOD HAVING PRECISE ION CONTROL
Document Type and Number:
WIPO Patent Application WO/2023/138272
Kind Code:
A1
Abstract:
A direct air capture carbon dioxide energy saving system and method having precise ion control. The system comprises, connected in sequence, an air delivery device (1), an air distribution device (2), and a CO2 adsorption device (3) having a built-in high CO2 adsorption capacity humidifying adsorbent, wherein the CO2 adsorption device (3) is provided with a spraying device (4); a valence state ion screening device (5); an acid-base fluctuation regeneration device (6); and a CO2 regeneration device (7). According to the system and the method, at normal temperature and normal pressure, electric energy that cannot be fed into the grid can be consumed, so that CO2 having an air concentration can be distributed and enriched to CO2 having a concentration of 95%, for industrial applications or biological applications.
