SYSTEM AND METHOD FOR AUTOMATIC CONTROL OF DIFFERENTIAL PRESSURE IN A BAGHOUSE SYSTEM

摘要

Systems and methods for automatic control of a baghouse fabric filter system as a single unit to maintain a consistent pressure drop are disclosed. The fabric filter system may be a pulse jet cleaning system, and a controller may be provided to receive inputs from pressure sensors and other components and to control activation of pulse pipes for cleaning filter bags. The controller may adjust parameters including the dwell time between pulses, the duration of each pulse, and the pulse air pressure. The controller may further optimize these parameters to provide the minimum cleaning necessary per pulse to achieve the consistent differential pressure. By continuously adjusting the parameters, the system maintains the maximum amount of filter cake on the bags to promote optimal emissions control performance.

1. A filter system comprising:
at least one compressed air header; at least one pulse pipe connected to the header; at least one valve configured to control air flow from the at least one header to the at least one pulse pipe to generate air pulses; a plurality of filter bags; a differential pressure sensor; and a controller configured to activate the at least one valve and adjust one or more of a plurality of parameters associated with emitted air pulses, wherein the controller is configured to automatically adjust the parameters to maintain a consistent different pressure across the filter system.
