1. An air treatment apparatus for removing carbon dioxide (CO2) from the atmosphere, the air treatment apparatus comprising:
an adsorbent reactor chamber;
two rectangular openings in the walls of the adsorbent reactor chamber, wherein each of the two rectangular openings are disposed on opposite sides of the adsorbent reactor chamber;
at least one valve frame affixed around each of the two rectangular openings;
a double-door valve comprising two rectangular valve elements associated with each valve frame and attached at opposite sides of the valve frame, wherein each of the two rectangular valve elements of the double-door valve is capable of opening in a direction outward from the adsorbent reactor chamber;
at least one sealing element between the two rectangular valve elements and each valve frame; and
at least one primary actuation mechanism for selectively moving the two rectangular valve elements between an open position and a closed position,
wherein, when the two rectangular valve elements are in the open position a flow of gas may enter and exit the adsorbent reactor chamber through the two rectangular openings, and
wherein, when the two rectangular valve elements are in the closed position, the two rectangular openings of the adsorbent reactor chamber are sealed to prevent flow of gases into or out of the adsorbent reactor chamber through the two rectangular openings.
