摘　　要：针对小型化工厂废水处理中,双级活塞推料离心机固液分离产能过大,从而要求设计生产能力在300 kg/h^500 kg/h,残余含湿率≤5%的双级活塞推料离心机的问题,研究了影响生产能力的推料行程、滤饼厚度、推料次数以及影响残余含湿率的分离因数、分离时间等相关参数。采用了P-40双级活塞推料离心机的实际运行和分离效果参数,应用换算法对P-25小型双级活塞推料离心机的推料行程、推料次数、转鼓过滤长度、转鼓转速等运行参数进行了设计,确定了转鼓直径。研究结果表明:生产能力和残余含湿率在理论上可满足用户的要求;P-25双级活塞推料离心机在实际运行中生产能力达到300 kg/h^550 kg/h,残余含湿率在4.5%~5%之间,达到了预期效果。Aiming at the problem of excessive solid-liquid separation capacity of two-stage piston pusher centrifuge in waste water treatment for small chemical plants,and a two-stage piston pusher centrifuge with the production capacity of 300 kg/h^500 kg/h and the residual moisture content of≤5%is required to be designed,the parameters that affect the production capacity,such as push stroke,thickness of filter cake,pushing times,as well as the parameters that affect the residual moisture content rate,such as separation factor and residual moisture content were studied.Based on the practical operation and separation effect parameters of P-40 two-stage piston pusher centrifuge,that operating parameters of P-25 small-sized two-stage piston pusher centrifuge such as push stroke,push times,basket filter length and basket rotate speed were designed by conversion method,and basket diameter was determined.The results indicate that the production capacity and residual moisture content can meet the requirements of users in theory by calculating.The production capacity of P-25 two-stage piston pusher centrifuge reaches 300 kg/h^550 kg/h in actual operation,and the residual moisture content is between 4.5%~5%,which achieves the expected effect.
