METHOD AND EQUIPMENT FOR CLEANING AIR

摘要

PURPOSE:To efficiently clean polluted air and to enhance stability by collecting dust incorporated in the polluted air by gas-liquid contact and sterilizing various bacteria incorporated in the polluted air with aqueous ozone having low concentration. not more than safety standard value by circulation contact. CONSTITUTION:In the case of removing dust, etc., incorporated in polluted air by feeding the polluted air to a gas-liquid contact type collection part 30 through an inflow port 12, washing water used for the abovementioned gas-liquid contact is circulated by utilizing a circulation duct 23. Gaseous ozone or aqueous ozone is fed to the circulated washing water from an ozone mixer 25 and the above-mentioned polluted air is sterilized by utilizing the obtained aqueous ozone of 0.03-0.2ppm. As a result, cleaning of the polluted air can be efficiently performed and also stability can be enhanced.
