Abstract
A method and apparatus for cleaning baghouse filters includes a baghouse having an upper, clean air chamber and a lower, dirty air chamber. Particulate-laden air is introduced into the dirty air chamber, particulates are collected onto filters suspended within the dirty air chamber, and the clean air exits outwardly up through open tops of the filters into the clean air chamber. A compressed air supply, a pressure regulator, a controller, a transducer, and a gauge are provided. Piping supplies compressed air from the supply to a header located at the baghouse, where the compressed air can be distributed to a selected row of filters for the purpose of cleaning the filters in the row. The transducer receives static pressures of air from the clean and dirty air chambers, respectively, and generates an electrical signal indicative of the differential air pressure between each of the chambers. This electrical signal is transmitted to the controller, which utilizes the signal to adjust the regulator so that the compressed air used for cleaning the filters is proportional to the pressure differential between the clean and dirty air chambers of the baghouse.
