The experimental study was carried out to optimize the nozzle shape and dimension for the pulse clean- ing of a ceramic filter candle.A bench scale unit of ceramic filter consisting of four commercial filter elements was used to measure the traces of the transient pressure around the nozzle and the overpressure in the filter cavity during the pulse-jet injection of pulse gas.Overpressure in the filter cavity is related to the pulse cleaning force.Nozzle design is concerned to increase the overpressure at the open end of filter element of pulse cleaning inlet,as well as to minimize the consumption of pulse gas.Convergent nozzle induces more secondary flow and generates higher pulse cleaning effect than straight nozzle.Nozzles of different convergent ratio(ratio of outlet to inlet diameter of nozzle)by changing the convergent angle and height were tested.The outlet diameter of convergent nozzle seri- ously influences the cleaning effect.The optimum convergent ratio increases with the increase of pulse gas pressure. The nozzle position(distance of nozzle tip from the open end of filter inlet)is also important to decide the nozzle dimension.Nozzle of large outlet diameter accepts high pressure of pulse gas to provide large overpressure in the filter cavity of top position by applying long distance.
