PURPOSE: A drain apparatus for a gas diffusion tower is provided to prevent the infiltration of rainwater into a gas diffusion tower and easily drain rainwater infiltrated or condensate produced during ventilation of gas. CONSTITUTION: A drain apparatus for a gas diffusion tower comprises a diffuser pipe(140), an inlet cell(150), a rainwater cover(151), and an exterior cover(160). The diffuser pipe has a plurality of discharge holes(141). The inlet cell is connected to the diffuser pipe so that a chamber is formed on the upper side of the diffuser pipe. The rainwater cover blocks up the top of the inlet cell. The exterior cover is installed between the inlet cell and the diffuser pipe to form a discharge path for gas emitted through the discharge holes. A rainwater guide(170) is installed on the upper side of the inlet cell and guides rainwater to the exterior of the cover so that the rainwater does not infiltrate into the diffuser pipe. A partition(142) is installed on the outer lower side of the diffuser pipe to block the bottom of the diffuser pipe and prevent rainwater or condensate from infiltrating into a vent pipe.
