Rates of mass transfer at a rotating cylinder of the hexagonal cross section were measured by the limiting current method. A drag‐reducing polymer diminished the speed of mass transfer depending on polymer quantity and rotation speediness. Rotating hexagonal cylinders provided higher degrees of mass transfer than circular rotating cylinders under identical conditions. The performance of rotating hexagonal cylinders in eliminating Cu²⁺ from dilute liquids was examined and found to be satisfactory. Besides the diffusion‐controlled electrochemical reactions like anodic oxidation of organic contaminants, the reactor can remove organic pollutants via catalytic diffusion‐controlled reactions. The high degree of heat transfer from the cylinder to the liquid would prevent possible hot spots, catalyst deactivation, and decomposition of products.

适用于水污染控制的旋转六边形圆柱反应器的传质行为

通过极限电流法测量在六边形横截面的旋转圆柱体处的传质速率。减阻聚合物取决于聚合物数量和旋转速度而降低了传质速度。在相同条件下，旋转的六角形圆柱体提供的传质程度高于圆形的旋转圆柱体。旋转六角圆柱体消除Cu ^2+的性能检查了从稀液体中提取的残留物，结果令人满意。除了有机污染物的阳极氧化等扩散控制的电化学反应外，反应器还可以通过催化扩散控制的反应除去有机污染物。从气缸到液体的高度热传递将防止可能出现的热点，催化剂失活和产品分解。
