Carbon Monoxide(II) Purification in the Plenum Valves of the Building Ventilation System

Abstract

The results of field studies on the selection of the best way to clean the supply air from carbon monoxide(II) in urban buildings are presented. A pilot plant has been developed to clean the supply air in the outer wall of the building using various sorbents, chemisorbent. Various methods for purifying supply air have been investigated. The isotherms of adsorption of carbon monoxide(II) on activated carbon, shungite, zeolite for calculating the volume of purified gas at constant air temperature were constructed according to the Freundlich equation, and empirical dependences of the concentration of carbon monoxide(II) on time were obtained using various options for purification of the supply air. The research results showed that the best sorbent for cleaning the outside air of carbon monoxide(II) is shungite + silica gel + manganese dioxide + zeolite, the cleaning efficiency was 95.35 %, and the second most effective sorbent for cleaning was the shungite from Karelian field – 86.5 %. The results can be used to clean the internal air of buildings with plenum valves along the height of the facade.
