Abstract

The invention relates to the technical field of electrolytic reaction, in particular to a continuously-operated supergravity multistage concentric cylinder type electrolytic reaction device and a process thereof, which solve the problem that the traditional supergravity electrolytic reaction device is only applicable for small-batch gap operation. The device comprises an insulated shell, a cathode disc provided with a cylinder cathode and an anode disk provided with a cylinder anode, wherein the cylinder anode and the cylinder cathode are concentrically and alternately arrayed; the cathode disk stands relative to the shell; and the center of the anode disk is connected with a rotating shaft capable of rotating at high speed. The process comprises the following steps that: electrolyte enters the center of the reaction device from a liquid phase inlet; liquid passes through various stages of cylinder type electrolytic baths formed by alternately arraying the cylinder anode and the cylinder cathode in sequence from the center along the radial direction; and the liquid is collected by the shell of the electrolytic reaction device and flows out from a liquid phase outlet. The invention has the benefits of continuously electrolyzing and being the continuously-operated supergravity multistage electrolytic reaction device and the process thereof which are suitable for industrial application.

Description

technical field [0001] The invention relates to the technical field of electrolytic reaction, in particular to a continuously operated high-gravity multi-stage concentric cylindrical electrolytic reaction device and process. Background technique [0002] During the electrochemical reaction, it occurs on the surface of the electrode, such as oxygen evolution, hydrogen evolution, chlorine evolution, etc., mainly in the form of bubbles attached to the surface of the electrode and electrolyte or dissolved into the electrolyte. When the current density increases, the generated bubbles will lead to an increase in the impedance of the electrolyte and the electrolytic cell, resulting in uneven distribution of overpotential and electrode potential, resulting in a decrease in electrode activity, which seriously affects the electrolysis effect and rate. [0003] Hypergravity conditions have a significant impact on the electrochemical reaction process, which can promote gas precipitatio...
