In this study, the flow by impingement at water dust collector with movable nozzle was analyzed by computational fluid technique. The velocity and vorticity of the dust collector were compared by positioning the nozzle to up and down. Also, the mean velocity were compared through three specific locations that were the diffuser inlet, movable nozzle surface and dust collector outlet. It can be checked that the vorticity and velocity magnitude are verified by the fluid solver of Fluent. As the result of this study, the movable nozzle located at 4cm down from initial position of the nozzle shows the great characteristics of vorticity and velocity distribution for dust collection.
