Abstract
There were many parameters that have an important influence on the system of pulse jet cleaning using in baghouse dust collectors. This study investigated the feasibility of optimizing the nozzle height and diameter parameters during pulse jet cleaning. A two-dimensional numerical model of a pulse jet system was used to analyze the effect of the nozzle height by using computational fluid dynamics (CFD). For simulations, we took into consideration the cleaning characteristics of the pulsed air jet system in the baghouse phosphate dust collectors of the UB (Drying unit of Beni-Idir) situated in Khouribga (Morocco). The pulse jet air around the cleaning nozzle was simulated to predict the effect of nozzle dimensions on the cleaning performance in terms of velocity distribution and pressure distribution. The influence of the nozzle height and diameter was discussed. Results showed that the pressure profile depends on both changes in height and nozzle diameter. The pressure increased with increasing nozzle height and decreased with larger nozzle diameter. Moreover, we found that the velocity is proportional to the nozzle diameter. Test results concluded that a lower nozzle height and a larger diameter are recommended for improving the pulse jet cleaning in the baghouse phosphate dust collector.
