Electrolysis system based on fully sealed selective powder electrolysis device

Abstract

The invention relates to an electrolysis system based on a fully sealed selective powder electrolysis device. The electrolysis system comprises the fully sealed selective powder electrolysis device (A) and an auxiliary device, wherein the auxiliary device comprises a catholyte storage tank (B), a solution conveying pump (C), a solution circulation tank (D), a solution circulation pump (E), a silicon rectification direct-current power supply (I), a compressed air tank (K) and a waste gas collection tank (L). The electrolysis system can be used for effectively improving the problems of low electrolysis current density, non-uniform current distribution, high solution impurity removal difficulty, long process flow, high production cost, high difficulty in product collection, low overall efficiency and the like of the traditional flat (frame)-type electrolysis device during an electrolysis process; electrolysis can be carried out under the condition of complex solution ingredients; in addition, the electrolysis system is efficient, reliable, simple in process flow, simple and convenient to operate, and low in cost.
