CHLORINE DIOXIDE GAS FUMIGATION DEVICE AND CHLORINE DIOXIDE GAS FUMIGATION METHOD

摘要

A chlorine dioxide gas fumigation device, according to one embodiment of the present invention, comprises: a mode selection unit for outputting a mixing mode signal corresponding to a mixing mode selected from among a plurality of modes; a controller for outputting a first control signal corresponding to the mixing mode according to the mixing mode signal; a power supply unit which supplies a high-concentration mode current during a high-concentration mode time according to the first control signal, and which supplies a low-concentration mode current smaller than the high-concentration mode current during a low-concentration mode time longer than the high-concentration mode time; and a gas generation unit for generating chlorine dioxide gas by electrolyzing a raw material solution according to the supply of the high-concentration mode current and the low-concentration mode current.
