Abstract
The report gives results of a study of the performance of a high-velocity pulse-jet filter. Such filtration has distinct advantages over low-velocity filtration in that the equipment required to clean a gas stream is reduced in size and initial cost as velocity increases. Although high filtration velocity causes a number of problems, many of them are dealt with in the report. Location of the gas inlet to the filter was found to affect penetration and pressure drop; both were higher for inlets near the bottom of the filter housing. Fabric type was also found to affect performance by affecting the amount and characteristics of the dust deposit accumulated. Fabric surface properties help explain the nature of this deposit. These ideas and others were used to develop a mathematical model for pressure drop in a pulse-jet cleaned filter. The model can be used to predict pressure drop under stable or variable operating conditions, and to predict operating conditions that cause unstable filter operation. An understanding of particle/fiber interactions is essential to understanding the collection characteristics of a felt fabric. Under certain conditions, particles bounce on impact with fibers. An adhesion probability was determined and found to depend on incident particle kinetic energy.
