Electrolytic bath provided with plurality of vibration web plates

Abstract

The invention discloses an electrolytic bath provided with a plurality of vibration web plates. The electrolytic bath comprises an electrolytic bath body; the electrolytic bath body is divided into a cathode chamber and an anode chamber by a separation board; the cathode chamber is provided with a non-reaction electrode; the anode chamber is provided with a reaction electrode; the reaction electrode is connected to an eccentric wheel via a driving rod; the reaction electrode is formed by overlapping 2 to 10 pieces of metal screen plates via connecting pieces; each piece of metal screen plate is connected to a power supply via a current-limiting resistance; and the bottom of the electrolytic bath body is provided with a float-controlled valve dirt discharge groove. The electrolytic bath possesses advantages of large working electrode area, uniform and stable distribution of current and potential, and excellent mass transfer performance.

Description

technical field [0001] The invention relates to an electrolytic cell, in particular to an electrolytic cell with a multi-layer vibrating net plate. Background technique [0002] The electrolytic cell used in the inorganic electrolysis industry is relatively mature, generally a single plate electrode electrolytic cell, in the electrolytic synthesis of organic matter, due to the existence of side reactions in parallel or in series, this type of electrolytic cell is generally not applicable, so many researches at home and abroad are devoted to Development of electrolyzers suitable for organic synthesis. In organic electrochemical synthesis, there are often requirements on the mass transfer rate on the electrode surface when performing electrochemical reactions. Since the rate of organic electrochemical reactions is generally low, in order to have industrial value, the current density of the electrolytic cell used is generally required to be around 1000A / ㎡, and to adapt to this...

AI Technical Summary

Problems solved by technology

Since the rate of organic electrochemical reactions is generally low, in order to have industrial value, the current density of the electrolytic cell used is generally required to be around 1000A / ㎡, and to adapt to this current density, the flow rate of the electrolyte needs to be above 1m / sec. In order to meet the requirements of mass transfer and selectivity, when using a fixed electrode at such an electrolyte flow rate, if the flow channel is very narrow, the pressure drop of the electrolyte flow is too large; if the flow channel is wide, the required electrolysis The amount of liquid circulation is too large, both of which will cause great trouble to industrial equipment
