摘要:
为提高药剂与水的混合效率、改善水处理的效果，对采用水力混合方式的漏斗式涡流反应器进行了数值模拟和水力特性试验研究．结果表明，依靠切向进水和进出水口的高差可使反应器内水流形成稳定涡旋，依靠喉口可强化返混作用．反应器的水力流态介于完全混合式和推流式之间，混合效率受切向进水流速的影响，进水流速为0.1～1.5 m/s 时涡旋尺度接近药物颗粒直径，有利于颗粒之间的碰撞，混合效果好；进水流速为0.2 m/s 时，混合效果最好．同时反应器只需通过水泵控制，大大节省了耗能．
Abstract:
To enhance the mixing effectiveness of water and agent and to improve the efficiency of water treatment, the numerical simulation and hydraulic characteristics of a funnel vortex reactor by the hydraulic mixing were studied. The results showed that the stable vortex could be obtained by means of the tangential inflow and height difference between inlet and outlet of the reactor. The aditus laryngis could effectively enhance the backmixing function. The flow regime was between continuous flow and plug flow, and the mixing efficiency was only dependent on the velocity of inflow. When the inlet velocity ranged from 0.1 m/s to 1.5m/s, the vortex size was close to the diameter of agents particle, in favor of the collisions and mixing among the vortex.The best effects of mixing could be achieved when the inflow velocity was 0.2 m/s. Meanwhile, the reactor only needed to be controlled by the pump, and then the energy consumption would decreased considerably.
