摘要
本文针对垃圾渗滤液用厌氧反应器采用的枝状、环状、网状布水器建立流场,分别模拟废水进入布水器后的流动状态,探讨了不同布水器结构形式及支管出水角度等主要参数对布水效果的影响。模拟结果表明,环状布水器中各出口流量分布最为均匀,且当支管与环形主管间的夹角增大时,各出口流量进一步变得均匀。当支管与主管轴线夹角为60°时,布水均匀性最好。
In this paper,the flow field was established for the branch,ring and mesh water distributors used in the anaerobic reactor for landfill leachate,and the flow state of the wastewater after entering the water distributor is simulated respectively.The effects of main parameters such as different water distributor structure and branch outlet angle on the water distribution effect were discussed.The simulation results show that the flow distribution of each outlet in the annular distributor is the most uniform,and when the angle between the branch pipe and the annular main pipe increases,the flow distribution of each outlet becomes more uniform.When the angle between the branch pipe and the main pipe axis is 60°,the water distribution uniformity is the best.
