Technical principle and working properties of sludge dredging by airlift water jet

摘要：

　　The sludge in rivers,dams and municipal facilities have caused increasing attentions.The airlift water jet can make density difference between sludge and the environment,and make the sludge float automatically.A kind of airlift water jet dredging system is designed and its work properties are analyzed.Mechanical structure analysis shows that the airlift water jet dredging device is low energy consumption and easy of maintenance with low cost.Numerical Simulation shows that the bubble volume ratio will affect the flow performance:the bigger bubble volume ratio will generate higher transport capacity.
