Abstract

In this paper a new process is presented for improving efficiency of cyclone de-dusting systems. The cyclone is coupled with a specially designed cylindrical chamber which includes a rotating tube inside it with air impinging nuzzles, drilled on the peripheral surface of the tube. The nuzzles help in pushing and throwing the particles to the outer radius distances during downward flow of dust included air stream inside the chamber. In this way dust particles will become concentrated near the surface of the cylindrical chamber which is then collected from a recycling stream, taken from the higher radius zone of the chamber in the lower part and passed through a cyclone for dust removal. The exhaust dusty flow of the cyclone is also recycled to the jet-impingement chamber for further de-dusting. Experiments were conducted on the apparatus by feed stream input to the chamber in such a way that the performances of chamber alone can be investigated with respect to the three variables; feed stream, recycle stream and jet-impingement stream.
