The demand for effective gas filtration methods has grown due to the increasing need to control the loss of raw materials in many industrial activities. Emission control equipment is essential in production processes, and can be used to recover raw materials or byproducts. In the search for greater efficiency in gas filtration, new methods have been developed and enhanced materials have been formulated for the collection of increasingly smaller particles, with high efficiency now achieved even for nanoparticles.
Although these studies have studied the influence of the electrostatic charge in the filtration, a study should be important about the forming dust cake and their parameters after electrostatic discharge. Thus, this study has proposed to reduce the loss of particulate material using of hybrid electrostatic filtration system for particle. The hybrid filter is the junction of fabric filter and corona charge in a unique process. An electrostatic discharge of 0 to -4 kV on cement particles has been used. The particles were transported by a flow of dry air and were charged using corona charger, prior to deposition on the filter (glass fiber) where the dust cake was formed. This procedure was realized in the Environmental Control Laboratory of DEQ-UFSCar. The filtration curves obtained showed that...
