This invention discloses a device and method for the efficient degradation of
ozone through a three-phase synergistic process. The device includes an atomization
system, a
spray tower with a gas absorption pump, and an
auxiliary system. The
spray tower contains an organic-modified
activated carbon layer.
Ozone gas is forcibly drawn in by the absorption pump, enriched by the adsorption layer, and then comes into countercurrent contact with organic droplets, undergoing synergistic degradation under UV excitation and constant temperature conditions. Using a 0.5 g / L
cysteine-
ascorbic acid-
glutathione mixed solution (pH=9.4), a UV intensity of 1.34 W / m², a temperature of 39.5℃, an
activated carbon addition height of 2.54 cm, and a gas flow rate of 21.1 L / h, the
ozone degradation rate reaches 90.957%. This invention is particularly suitable for
ozone purification in microenvironments.
