METHOD OF CLEANING AIR TO REMOVE CARBON MONOXIDE AND FILTER MODULE FOR REMOVING CARBON MONOXIDE FROM AIR Russian patent published in 2006 - IPC B01D53/86 B01D53/04 

FIELD: gas treatment.

SUBSTANCE: method comprises passing air through cooled adsorbent bed and then through carbon monoxide oxidation catalyst bed based on manganese and copper oxides. Thereafter, air is passed through heated adsorbent, after which air stream direction is reversed and simultaneously adsorbent is heated at its inlet and heated at its outlet. Cooling and heating are accomplished with the aid of thermoelectric elements, wherein current direction switching is made synchronously with air stream direction reversal. Filter module contains adsorber connected to cartridge at its exit. Cartridge contains carbon monoxide oxidation catalyst. A second adsorber is mounted on the outlet of cartridge. Adsorbers are connected to air stream switch and made with internal ribbing coupled with thermoelectric elements. The latter connected to power source over current direction switch.

EFFECT: simplified process, increased reliability, reduced power consumption, reduced apparatus dimensions, and avoided operation suspension for performing regeneration.
