Abstract
Overweight of dust concentration is a common problem happened in most coal mine that not only affects workers’ normal work ,but also brings a great potential safety hazard to mine.New wet duster’ operating principle is that wind pressure and water pressure which generated in working surface pipeline network go through the nozzle jet and produce negative pressure leading the dust into dust catching pipe, and then the dust removed.According to optimizing the nozzle structure can increase spray’s cone Angle inside the shower nozzle,then the dust removal ability will be improved.The paper built the nozzle’ 3D model and the water’ the river basin model in SolidWorks ,then meshed them in Gambit and finally analysis the pressure and nozzle size’s influence on fluid’s pressure and velocity with Fluent’s flow field simulation.
