Fluid Dynamics Study of the Influence of Direction of the Gas Flow in Fabric Filter
The new environmental laws, as well as the search for technologies of accuracy production, have leaded companies to search for more and more efficient equipment. Regarding the emission of particulate material, the fabric filter is the most used equipment in the industry, for presenting a high efficiency and low operational costs, essential in any project of this type. In the search for a more efficient and economic filtering operation, this work studied, by techniques of CFD, the modification of the traditional way of feeding a filtering box (usually accomplished by the side of the system) by another in which the feeding was accomplished through the bottom of the equipment, in order to review the distribution of volumetric outflows in the bags and pressure drop. The fluid dynamic simulations had shown that the feeding fluid - through the bottom of the filtering box - provides an inferior operational pressure drop and a better distribution of fluids between the bags.
