Reducing Compressed Air Consumption for Filter Bag Cleaning with Advanced Cleaning Controls and Cleaning System Design

The regeneration of filter media in dust collection systems is an important element in the reliability of process equipment, but excess compressed air pressure causes premature filter bag failure in addition to unnecessary electrical consumption. Improvements in pulse-jet technology have enabled the use of filter bags beyond 16 feet which help reduce capital costs of new baghouses. The inherent issue with regenerating the filter media at long bag lengths is the capacity and operation of the pulse valve against the process flow. By utilizing an advanced cleaning controller in a segmented baghouse design, cement producers can extend filter media life and lower compressed air consumption. Offline cleaning requires lower compressed air pressure to regenerate the filter media while gently cleaning the filter bags, therefore reducing operating costs and extending filter media life without the dramatic airflow swings of compartment isolation.
