Abstract
Methods and systems for detecting the presence of a leak in a baghouse bag installed in a baghouse system having at least one compartment. The methods include using a system to acquire electrical signals corresponding to the opacity of gas flow through an outlet of a baghouse system during a start-up of one or more compartments of the baghouse system and comparing the electrical signals corresponding to the opacity of the gas flow with electrical signals characteristic of a leak in at least one of the baghouse bags of the baghouse system.
Claims22
A method of detecting a leak in a bag installed in a baghouse system, comprising the steps of:
- positioning a sensor to measure opacity in an outlet of a baghouse system having at least one compartment;
- measuring opacity of gas flow through the outlet during start-up of one or more compartments in the baghouse system;
- generating electrical signals corresponding to the opacity measured by the sensor;
- and
- comparing the electrical signals corresponding to the opacity measured by the sensor at least during start-up of one or more compartments with a reference characteristic of a leak in a bag of the baghouse bag system.
A method of detecting a leak in a bag installed in a baghouse system, comprising the steps of:
- positioning a light emitting diode in an outlet of a baghouse system having at least one compartment;
- positioning a sensor to measure light emitted from the light emitting diode to measure opacity in the outlet of a baghouse system;
- measuring opacity of gas flow through the outlet during start-up of one or more compartments of the baghouse system;
- generating electrical signals corresponding to the opacity measured by the sensor;
- and
- comparing the electrical signals corresponding to the opacity measured by the sensor at least during start-up of one or more compartments with electrical signals characteristic of a leak in a bag of the baghouse bag system.
A system for detecting a leak in a bag installed in a baghouse system, comprising:
- a sensor positioned to measure opacity in an outlet of a baghouse system having at least one compartment, where the sensor is adapted to measure opacity of gas flow through the outlet at least during start-up of one or more compartments in the baghouse system;
- and
- a processor adapted to generate electrical signals corresponding to the opacity measured by the sensor and compare the electrical signals corresponding to the opacity measured by the sensor during start-up of one or more compartments with electrical signals characteristic of a leak in a bag of the baghouse bag system, where the processor is adapted to process electrical signals before and at least during start-up of one or more compartments of the baghouse system.
A system for detecting a leak in a bag installed in a baghouse system, comprising:
- a light emitting diode positioned in an outlet from a baghouse system having at least one compartment;
- a sensor positioned to measure light emitted by the light emitting diode to measure the opacity of gas flow in an outlet from the baghouse system, where the sensor is adapted to measure opacity of gas flow through the outlet at least during start-up of one or more compartments in the baghouse system;
- and
- a processor adapted to generate electrical signals corresponding to the opacity measured by the sensor and compare the electrical signals corresponding to the opacity measured by the sensor during start-up of one or more compartments with electrical signals characteristic of a leak in a bag of the baghouse bag system, where the processor is adapted to process electrical signals before and during at least start-up of one or more compartments of the baghouse system.
A baghouse filter system comprising:
- a housing comprising at least one compartment, each compartment comprising a first chamber and a second chamber, an inlet into the first chamber and an outlet from the second chamber, and a plurality of filter bags operatively positioned between the first and second chambers, the filter bags capable of filtering airborne particulate matter;
- a blower operatively connected with the housing and capable of flowing air from the inlet through the filter bags and through the outlet;
- a sensor positioned to measure opacity of gas flow from the outlet of the baghouse filter system, where the sensor is adapted to measure opacity of gas flow through the outlet at least during start-up of one or more compartments in the baghouse system;
- and
- a processor adapted to generate electrical signals corresponding to the opacity measured by the sensor and compare the electrical signals corresponding to the opacity measured by the sensor during start-up of one or more compartments with electrical signals characteristic of a leak in a bag of the baghouse bag system, where the processor is adapted to process electrical signals before and during start-up of one or more compartments of the baghouse system.
