PURPOSE: A device for supplying brine into an electrolyzer for preparing sodium hypochlorite is provided to ensure simple structure by removing the needs of a mixer for dissolving of salt, a concentration measuring sensor, an electric valve, a separate water tank, etc. CONSTITUTION: A device for supplying brine into an electrolyzer for preparing sodium hypochlorite comprises a salt storage tank(10), a water level control pipe(20), a water supply pipe(30), a fresh water supply pipe(30a), a water level control valve(40), a brine discharge pipe(30b), and a diluted brine supply pipe(30c). The salt storage tank stores salt and water together, where the amount of salt is always more than the amount of water. The water level control pipe is formed into a hollow body that is installed lengthwise inside the salt storage tank and connected through a bottom outlet to the salt storage tank. The water supply pipe supplies fresh water from outside. The fresh water supply pipe is branched from the water supply pipe to supply the fresh water into the water level control pipe. The water level control valve is installed in the fresh water supply pipe to maintain uniform water level in the water level control pipe. The brine discharge pipe discharges saturated brine from the bottom of the salt storage tank. The diluted brine supply pipe mixes the fresh water provided through the water supply pipe with the saturated brine provided through the brine discharge pipe and supplies the mixed saturated brine to an electrolyzer.
