Abstract
A method for controlling the cleaning of multiple-baghouse fabric filter systems. Each baghouse includes a plurality of compartments and a cleaning system of a type which cleans the compartments in a compartment-by-compartment sequence and which allows all compartments not being cleaned to maintain the baghouse on-line even during a cleaning operation. The particular cleaning system disclosed more particularly is of the reverse gas flow type. A normal characteristic of reverse gas flow cleaning is that system pressure drop goes through sequential peaks and minimums. In the systems disclosed herein, the cleaning cycles of the individual baghouses are staggered in a manner such that the peak resistance during cleaning of one baghouse does occur at the same time as a lower and offsetting resistance of another baghouse. Thus, peak pressure drop of the system as a whole is reduced. Moreover, the difference in pressure loss from peak to minimum is reduced.
