Optimization of Bag Filter in a Cement Factory in Order to Increase of Dust Collection Efficiency

F. Mohsenzadeh, K. Naddafi, J. Nouri and A.A. Babaie    

Abstract: The bag filters are important equipments in cement factory. In these filters current flow that includes gas and dust cross through the pores are located in the stuff filter and filtrate by that remaining on the bag. Afterward, by dust increase on the bag, the filter is shaken until dust collecting leads to exit hopper. This system in this project is called mechanical method. In order to obtain a better operation after introducing to the operation mechanism, the same steps like create good situation for maintain for maintenance and repairs by consideration on important fragment and appoint minority of stock in the stores, carry out the planning of the maintenance and repairs, improvement of stock mandatory. Then, the pressures were measured in various part of filter system and controlled the pressure drop. By inspection of various kinds of bags used in the filter, 550 g m-2 polyester bags showed a better performance and parameter effective in tearing and wearing of bags which were recognized. Also by installing timer on the shaking system, the shaking periods of bags were increased. In order to increase dust cake layer and better performance of deducting and bags life time. Assessment of operation on a sample bag filters show that the ready operation time of filter was increased about 200% and out put of dust amount decreased to the below of the standard limits.
