The cathodic membrane reduction method for preparing hydrogen peroxide involves the generation of hydrogen peroxide through a two-electron reduction reaction of oxygen on the cathodic membrane.When the reduction reaction of oxygen occurs on the cathode membrane,the accumulation of hydrogen peroxide,a product of the two-electron reduction reaction,on the membrane surface will inhibit the subsequent reaction and affect the preparation effect.Therefore,suitable working conditions need to be selected in production to improve the preparation ability.Change the structure of the cathode chamber and the flow rate of the cathode liquid,and analyze the flow field structure and hydrogen peroxide concentration distribution under corresponding conditions through numerical simulation.Screen out the structure and flow rate conditions that are conducive to hydrogen peroxide preparation,conduct experimental verification,study the influence of the cathode chamber structure and flow rate on hydrogen peroxide production,and propose a more efficient plan for hydrogen peroxide preparation,this provides further theoretical support for the industrial process of preparing hydrogen peroxide by cathodic membrane reduction method.
