An device for absorbing carbon dioxide in the air

摘要

An absorptive device to capture carbon dioxide comprising a rotating packed bed (1) includes a sealed housing (11), in which a filler (17) is speedily rotated by a motor (16) . A liquid distributor (18) on the filler (17) center communicates with an absorbent entrance (15) . An air pump (2) impels the air into the housing (11) ; an absorbent reservoir (3) saves an absorbent extruded from an absorbent exit (13) ; a water pump (4) forces the absorbent within the absorbent reservoir (3) into the housing (11). The absorbent flows through the liquid distributor (18) into the filler (17) center; the air enters the center through the filler (17). The absorbent spurts via the centrifugal force created by the super gravity field at a speedy rotation more than 100G to meet the carbon dioxide in the air in the filler (17) center, thence achieving a chemical absorption to absorb carbon dioxide, discharging redundant air from the air exit (14), and recycling the absorbent with the absorption of carbon dioxide in the absorbent reservoir (3).
