| 中文摘要: |
| 常规三维电极反应器易堵塞，流场不稳定、不规律导致传质效果极差，使反应器效率降低。设计了一种携带新型串束式泡沫镍三维电极粒子的电催化反应器，可有效降解有机废水，并保证内部流场的稳定性。为得到复杂内部结构下反应器流场特征，采用数值模拟法对反应器的流场进行模拟计算，以研究反应器流场分布情况。结果表明：电催化反应区域（粒子电极区域）流场稳定均匀；反应器内部结构对流场分布的影响明显，槽体中央的棒状阳极周围流场速度小，流动不规律容易产生流场死区；提高转速有利于使反应区流场的均匀化，不利于棒状阳极周围流体的传质。 |

| The conventional three dimensional electrode reactor is easy to be blocked, and the unsteady flow field leads to poor mass transfer efficiency. A catalytic reactor that carring new bunches of nickel foam three dimensional electrode particles was designed, which could degrade organic wastewater effectively, and could guarantee the stability of the internal flow field. In order to obtain the characteristics of the flow field in the complex internal structure, the numerical simulation method was used to simulate the flow field of the reactor. The results show that the electro catalytic reaction region (the particle electrode area) flow field is stable and uniform. The internal structure of the reactor has obvious impact on the distribution of flow field. The velocity field around the rod anode in the center of the tank is small, and the irregular flow is prone to produce flow dead zone. Improving the speed of the reaction zone is good to uniform flow distribution, but not good to the transfer of the fluid around the anode rod. |
