摘要
本文在侧重分析厌氧流化床下向流布水装置结构对流化床直观流化状况影响的基础上,结合最大容积有效利用率和最小启动回流量研究,最终得出在各方面都较优的厌氧流化床下向流布水装置的结构型式和布水装置的喷口流速范围.
This paper lays particular emphasis on the analysis ofhow the structure of the downflow wastewater distributors in an anaerobicfluidised bed(AFB)affect the visible fluiclization performance of theAFB.Based on this and the study of the maximum useful volume efficiencyand minimum return flow rate in AFB,the optimum structure of downflowwastewater distributors,which meets all of the needs of performance,and the range of control velocity of the sprayhead are eventually obtained.
