AI Technical Summary
In the process of preparing arsenic by redox reaction, the reactants tend to deposit at the bottom of the reaction vessel and cannot be stirred by the stirring mechanism, resulting in low reaction efficiency between the reactants and the redox agent.
An arsenic oxidation-reduction reactor was designed, comprising a reaction vessel, a cover plate, a bottom filter plate, a top filter plate, a hydraulic cylinder, and a circulation pump. The cover plate is raised and lowered by the hydraulic cylinder. Combined with the use of the filter plate, the reactants deposited at the bottom of the reaction vessel are brought into full contact with the oxidizing and reducing agent, thereby improving the reaction efficiency.
This method achieves full contact between the deposited reactants and the redox agents, improves the efficiency of arsenic reaction preparation, avoids damage to the hydraulic cylinder due to unilateral stress, and enhances the stability of the equipment.
