Abstract

The application discloses an electro-catalytic oxidation crystal primitive electrode plate and relates to the technical field of electro-catalytic oxidation. The electro-catalytic oxidation crystal primitive electrode plate comprises a glass steel shell, electrode seats are arranged at the upper end and the lower end of the glass steel shell, a plurality of crystal primitive plates and a plurality of electrode plates are arranged in a cylindrical mounting cavity, and the crystal primitive plates and the electrode plates are alternately distributed from top to bottom. In the cylindrical mounting cavity in the glass steel shell, the crystal primitive plates and the electrode plates are alternately distributed and are provided with a plurality of through holes, and gaps are left between the crystal primitive plates and the electrode plates. The application further discloses a firing process. When the glass steel shell is injected with an aqueous solution, the water flows through the through holes and then passes through each gap in stages. The unique design greatly increases the contact area of the aqueous solution with the electrode plates and the crystal primitive plates, optimizes the water flow path, effectively improves the mass transfer efficiency, enables pollutants to more quickly and fully contact the electrode surface and the crystal primitive plates, and further accelerates the oxidation-reduction reaction, thereby significantly improving the removal efficiency of the pollutants.
