Method for determining life of filters in bag house
First Claim
1. A method to determine an operational period for a filter in a filtration device comprising:
- determining an initial remaining operational period based on an installation date of the filter and an initial expected operational period, wherein the initial expected operational period is determined before the filter starts filtration;
periodically calculating a remaining actual operational period of the filter based on the remaining operational period based and an elapsed operational period of the filtration;
monitoring an opacity of gases through the filter, andperiodically adjusting the calculated remaining actual operational period based on the monitored opacity.

Abstract
A method for dynamically determining a remaining actual operational period for a filter in a filtration device including: determining an initial remaining operational period based on an installation date of the filter and an initial expected operational period; periodically determining a remaining actual operational period of the filter based on the initial remaining operational period based and an elapsed operational period from the installation date; monitoring at least one operating parameter in the filtration device; adjusting the remaining actual operational period based on the monitored operating parameter, and continuing to periodically determine the remaining actual operational period based on the adjusted remaining actual operational period and the elapsed operational period.

4. A method for dynamically determining a remaining actual operational life a bag filter in a bag house having a controller, the method comprising:
-
entering into the controller bag filter data and an installation date of the bag filter in the bag house; determining an initial bag filter life based on the bag filter data; decrementing the initial bag filter life to determine a remaining actual bag filter life and periodically decrementing the remaining actual bag filter life; monitoring a bag house operating condition, wherein the operating condition includes the opacity of a gas having passed through the bag filter; adjusting the remaining actual bag filter life based on the monitored bag house operating condition and periodically decrementing the remaining actual bag filter life, and replacing the bag filter at a time based on the decremented, adjusted remaining actual bag filter life. - View Dependent Claims (5, 6, 7)

8. An apparatus for dynamically determining a remaining actual operational life of a filter in a filtration device, comprising:
-
a non-transitory electronic storage containing data including an installation date of the filter, and data indicating an initial filter life; a sensor monitoring a particulate level in an outlet gas flow from the filtration device, and the sensor includes an exhaust gas opacity sensor in the outlet gas flow from the filtration device; a computer controller including an executable program stored on the electronic storage, wherein the execution of the program causes the controller to determine a remaining actual operational filter life based on a difference between a sensed level exhaust gas opacity provided by the opacity sensor and an expected opacity level, wherein the expected opacity level is determined by the controller based on opacity data stored in the electronic storage correlating the expected opacity level to an operational period of the filter, and a user terminal indicating the remaining actual filter life. - View Dependent Claims (9, 10, 11, 12, 13)
