The invention provides a device and a method for preparing high-purity gallium, aims at the problems of the existing high-purity gallium preparation technology and belongs to the fields of the preparation equipment and the preparation technology of the high-purity gallium. The device comprises an inner container, an outer container and a cover; the inner container is located inside the outer container; a cavity for cold water and hot water to circulate alternately is arranged between the inner container and the outer container; the drainage tube of the inner container extends out of the outer container via the drainage tube passing hole of the outer container; the inner container is hermetically connected with the outer container; the cover is fixed on the top of the device. The method comprises the following steps: putting coarse gallium into the inner container, introducing cooling water into the cavity between the inner container and the outer container to crystallize the gallium, when the solidification rate of the gallium is within the range of 90-97%, discharging the left liquid gallium and then introducing hot water to melt the gallium, next, introducing the cooling water, and repeating crystallization for 6-8 times to improve the purity, thereby obtaining the high-purity gallium of 6N or 7N. The application method of the device is simple and convenient to operate; the obtained gallium is high in purity and high in yield, and has favorable application prospect.
