The Influence of the Velocity of Filtration in the Formation and Removal the Dust Cake

The effective filtration area determined in a design of fabric filter depends on the filtration velocity, also known as air-to-cloth ratio that will be used. Low filtration velocities may demand big effective filtration areas. But then high filtration velocities may wear the filters out early. By searching for more efficient and economic equipments, this paper investigated the influence of the filtration velocity by formatting and removing the dust cake. Concluding that filtering at higher velocities a higher penetration of particles in the filter media occurs. Decreasing the filtration time and increasing the number which regenerates the cloth, consequently decreasing the life cycle of the filters.
