Summary
The ultimate objective is the development of a model, or series of models, starting with a fundamental study of the mechanics of filtration and culminating with a viable method to predict baghouse behavior (specifically, baghouse collection efficiency and distribution of particle sizes at the outlet as functions of time). In this report, a brief review of the literature is followed by detailed descriptions of what are referred to as the molecular model, the microscopic model, and the macroscopic model. The molecular model presents fundamental equations from which single-collector efficiencies may be determined. The microscopic approach results in a method to describe in theoretical terms the collection efficiency and performance of an assemblage of single collectors, viz., the combined filter medium and deposited cake. The macroscopic model - which is an attempt to represent actual baghouse behavior by correlating the theoretical results of the microscopic model with bench-scale, pilot-plant and field-test data - is as yet incomplete and is described in this report in qualitative rather than in quantitative terms. It is recommended that the microscopic model be used as the starting point in the development of a practical model, and that corrections based on empirical correlations be added. A technique is described for treating particle-size distributions and calculating the resulting collection efficiency and distribution of particle sizes at the outlet. Suggestions for future work on the project are also presented.
