Abstract:
1. A purifying apparatus comprising: a vessel in which an electroconductive liquid including impurities is stored; an electromagnetic force generation device which produces a downward or upward electromagnetic force that circulates the electroconductive liquid; a discharge device which discharges the impurities collected in a low-pressure portion based on a pressure difference in the electroconductive liquid produced by the electromagnetic force; a ferromagnetic structure through which the electroconductive liquid can pass arranged in a circulating flow of the electroconductive liquid in the vessel; and a magnetic force generation device which is arranged on an outer side of the vessel and gives a magnetic field to the ferromagnetic structure to make a magnetic force to generate in the ferromagnetic structure; wherein a metallic impurity circulated together with the electroconductive liquid by the electromagnetic force is caused to adhere to the ferromagnetic structure by the magnetic force, and wherein the ferromagnetic structure is disposed near a position where a flow direction of the circulating current of the electroconductive liquid is turned from the upward direction to the downward direction.
