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.
In order to improve the mixing efficiency of medicament and water and to improve the effect of water treatment, the numerical simulation and hydraulic characteristics test of funnel vortex reactor with hydraulic mixing were carried out. The results show that, by means of tangential inflow and height difference between inlet and outlet Can make the water flow in the reactor form a stable vortex, relying on the throat can enhance the back-mixing effect.The reactor hydraulic flow between complete mixing and push flow, the mixing efficiency is affected by the tangential inflow velocity, into When the water flow rate is 0.1-1.5 m / s, the vortex scale is close to the diameter of the drug particles, which is good for the collision between the particles and the mixing effect is good. When the flow rate is 0.2 m / s, the mixing effect is the best. Through the pump control, saving energy consumption.
