CO2 scrubber with moving bed structure

A carbon dioxide scrubber, comprising:

• a housing including:
• an adsorption chamber through which an adsorption airflow is directed;
• a regeneration chamber through which a regeneration airflow is directed;
• a divider wall separating the adsorption chamber from the regeneration chamber;
• a carbon dioxide sorbent bed configured extending across the adsorption chamber and the regeneration chamber, the carbon dioxide sorbent bed configured to adsorb carbon dioxide from the adsorption airflow into the sorbent bed and exhaust carbon dioxide from the carbon dioxide sorbent bed into the regeneration airflow;
• wherein the carbon dioxide sorbent bed is continuously movable through the adsorption chamber and the regeneration chamber;
• and
• a recirculation chamber defined in the housing and operably connected to the regeneration chamber by a recirculation damper, and configured to recirculate the regeneration airflow through the regeneration chamber;
• wherein the recirculation damper is disposed in a wall of the regeneration chamber dividing the regeneration chamber from the recirculation chamber.
