Research on movement characteristic parameters of MSW under pneumatic conveying environment

The intelligent pipeline pneumatic conveying method is a potentially efficient solution for the transportation of municipal solid waste (MSW). Due to the complex compositions and large volumes of MSW, the application of pneumatic conveying technology requires particular designs. However, the related research is limited. Here, we determined the physical properties of MSW by investigating their compositions. Specifically, we described the movement characteristics of waste under pneumatic conveying based on theoretical calculation, simulation, and preliminary trials. We obtained the key parameters during the pneumatic conveying of MSW including the no-load friction factor, the comprehensive resistance coefficient, the number of velocity heads lost and the shape factor of materials, which pave a way for the design of pneumatic conveying system. The obtained results provide supports for the research and development of waste pneumatic conveying technology.
