Equipment for preparing hydrogen peroxide by electrodes

The utility model discloses equipment for preparing hydrogen peroxide by an electrode, which comprises a reaction box, and the top of the reaction box is fixedly connected with a gas inlet pipe and a gas outlet pipe. By arranging a reaction box, a water inlet pipe, a water inlet valve, a power supply, a pressurizing mechanism, a water outlet pipe, a water outlet valve, a cathode piece, an anode piece, a temperature sensor and a pH value sensor, voltage is applied to the cathode piece, the solubility of oxygen in air in electrolyte is increased, the diffusivity of dissolved gas molecules is further improved, meanwhile, the diffusivity of a hydrogen peroxide precursor to an electrode is improved, and the hydrogen peroxide content is increased. The surfaces of the anode plate and the cathode plate are subjected to catalytic pyrolysis and impregnation loading treatment, the surface structure of the electrode is regulated and controlled, the hydrophobic performance of the electrode is enhanced, the efficiency of g
