Gas purification method and gas purifier

Abstract

The present disclosure provides a gas purification method and a gas purifier. The gas purification method includes: sucking external gas into an inner housing; supplying ozone to an interior of the inner housing to react with the external gas; irradiating the interior of the inner housing with ultraviolet rays to disinfect the external gas and decompose the ozone; discharging the purified gas out of the inner housing. After the external gas is sucked into the inner housing, ozone is supplied to the interior of the inner housing to react with the gas so as to perform sterilization and deodorization treatment; the interior of the inner housing is irradiated with the ultraviolet rays to further carry out sterilization treatment on the gas and decompose excess ozone.
