The invention provides a zirconium tetrachloride purification method based on a hydrogen reduction method, and provides a preparation device for the purification method, the preparation device comprises a machine body, a sublimation furnace is fixedly mounted in the machine body, a first impurity chamber is fixedly mounted below a timing mechanism, and a movable sleeve is movably mounted on the left side of an air bag; and a hydrogen switch is fixedly mounted in the movable sleeve, and a second impurity chamber is fixedly mounted above the recovery pipe. According to the zirconium tetrachloride purification method based on the hydrogen reduction method, when the passing temperature reaches 149.85 DEG C or above, impurities such as TiCl4 and SiCl4 sublimate into a second impurity chamber, an air bag expands to push a movable sleeve to move leftwards to open a hydrogen switch, and hydrogen enters a sublimation furnace to be subjected to a reduction reaction; and when the temperature in the sublimation furnace r
