METHOD AND DEVICE FOR THE SANITIZATION OF AIR

摘要

Method and device for the sanitization of air, which envisages a step involving suction of an air flow with suspended particles inside a treatment unit; a step involving electrostatic filtration of the flow, by means of the use of ionizing electrodes which generate an electric field and a positive corona discharge capable of positively charging the suspended particles so as to allow capturing thereof on special collector electrodes with an opposite charge or earth potential. It is then envisaged performing an ionization step with generation of a controlled concentration of ozone within the flow, which is achieved by means of the effect of the electric field produced during the electrostatic filtration step. The air flow is then subjected to an ionization step for generating a concentration of negatively charged ions of the said air flow, reacting with the positive ions output from the electrostatic filtration section which produce chemical compounds with an anti-bacterial activity. The concentration of negatively charged ions and the concentration of ozone form together a mixture with a marked microbicidal action for sanitizing the flow and/or the surfaces with which the said flow may come into contact.
