Abstract

Summary form only given. A method for disinfecting and purifying air is researched. A compounded reactor that is being designed for the method´s realization consists of a power inputting system and a microwave chamber, which includes cold plasma dischargers of DBD type. A reactor´s geometry provides spatially-homogeneous whole-volume processing without a deceleration of the airflow, while a reactor´s power input does not significantly increase the temperature of airflow passing through. Latest proofs of non-thermal microwave sterilization are of special interest for studying the synergistic anti-microbial effect of simultaneous use of non-thermal microwaves and plasmas. The influence of microwaves on increasing the non-equilibrium plasma´s recombination time and a method for amplifying the total effectiveness of a compounded reactor are also discussed.
