▎ 摘　　要

NOVELTY - The device has cathodes, anodes (1) and two filter elements that are arranged in an electrolytic cell. A filter portion comprises two filter plates (2), and a microporous filter membrane (3) is arranged between the two filter plates. The filter plate is provided with a through hole, and the cathode and the anode are respectively arranged at two ends of the electrolytic cell. The cathode and the anode are electrically connected to a power source, and the two filter portions are respectively arranged between the cathode and the anode of the electrolytic cell. The filter portion is perpendicular to the direction of the electric field. The two filter portions are provided with a liquid raw solution channel between the cathode and the anode. The liquid raw solution channels between the filter elements are sequentially connected in series to a pressure pump (5), a valve (6), a raw material storage tank (7), and purification liquid recovery tank (8). USE - Device for purifying liquid containing graphene. ADVANTAGE - The purifying efficiency is improved. The content of the conductive particles in the final product can be adjusted to achieve high-efficiency purification of the graphene-containing liquid. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the device for purifying liquid containing graphene.
