Boron-doped diamond (BDD) electrodes are the most effective and resistant electrodic materials to perform advanced oxidation processes. Having a reactor that can provide adequate hydrodynamic conditions is mandatory to use these electrodes effectively. In this work, the diamond anode electrochemical reactor (E3L-DAER) is designed to fulfill this necessity. Several features are included to improve its efficiency, like conic inlet/outlet, flow enhancers, and a reduced interelectrode gap. The fluid dynamic validation has been performed using computer fluid dynamics (CFD) calculations, residence time distribution (RDT) curves, and mass transfer analysis. The reactor has been made using a three-dimensional (3D) printing stereolithography (SLA) technique, which allows us to build chemical-resistant reactors with nonstandard and tailored features in a cheap and fast way. The obtained results demonstrate that the designed reactor has the required fluid dynamics properties to perform reliable BDD electrode studies and applications. Finally, a BDD electrode was used to test the production of different oxidants such as persulfate, peroxophosphate, and chlorine-derived species.

使用 3D 打印设计、验证和制造用于研究商用掺硼金刚石电极的定制电化学反应器

掺硼金刚石 (BDD) 电极是执行高级氧化工艺的最有效、最耐腐蚀的电极材料。为了有效地使用这些电极，必须拥有能够提供足够的流体动力学条件的反应器。在这项工作中，金刚石阳极电化学反应器（E3L-DAER）的设计就是为了满足这一需求。为了提高其效率，其中包含了多种功能，例如锥形入口/出口、流量增强器和减小的电极间间隙。使用计算机流体动力学 (CFD) 计算、停留时间分布 (RDT) 曲线和传质分析进行流体动力学验证。该反应器采用三维 (3D) 打印立体光刻 (SLA) 技术制成，使我们能够以廉价且快速的方式构建具有非标准和定制功能的耐化学反应器。获得的结果表明，设计的反应器具有执行可靠的 BDD 电极研究和应用所需的流体动力学特性。最后，使用 BDD 电极测试不同氧化剂的产生，例如过硫酸盐、过氧磷酸盐和氯衍生物质。
