Investigating migration velocity in the clinker cooler one stage electrostatic precipitator (made by ELEx, Hamon, and FLSmith Co.)

The rapid advances in human societies over the past decades have resulted in fast development of steel, cement, and other industries. Cement is one of the most important industries which plays a significant role in the development and prosperity of any country and worldwide. On the other hand, cement factories are among the major environmental plights and source of contamination. Accordingly, one of the main issues of these factories is controlling and preventing excessive emission of contaminants. Electrostatic precipitators are among the most important devices for controlling air pollution. One of the most important influential parameters affecting the efficiency of dust collection in the design of the electrostatic precipitator is the migration velocity. In this research, this parameter was studied in the electrostatic precipitators of ELEx, Hamon, and FLSmith companies, which are responsible for collecting the dust from Clinker coolers in cement factories. The results of the research suggested that the range of this parameter under the mentioned conditions was obtained as 8.7-11.5 Also, it can be stated that with elevation of the efficiency of mechanical dust collection of the equipment, one can achieve a better efficiency. This can be realized by properly exploiting chemical engineering, mechanical engineering, electricity engineering, as well as the experiences of scholars, thereby reducing costs, increasing the useful lifetime of equipment, and preventing environmental pollution.
