Abstract

Systems and methods for particle leak detection generally include a separation or collection device configured to filter particulate from a stream and a detection device downstream of the separation or collection device. The detection device can be positioned to detect particulate that passes the separation or collection device and can include a probe configured to detect the solid particles. The particle leak detection systems can be configured to be disposed on moveable systems, such as moveable systems in coke oven operations.

First claim

We claim:

1. A particulate detection system for use in an industrial facility, comprising:
a separation or collection device including a baghouse configured to filter particulate from an industrial gas stream including at least one of coal dust or coke dust;
a detection device downstream of the separation or collection device, wherein the detection device is positioned to detect particulate of the industrial gas stream that passes the separation or collection device, the detection device including a probe configured to detect the particulate,
wherein the detection device is configured to generate an action when a current associated with the detection device is outside a predetermined range, and
wherein the separation or collection device and the detection device are positioned on a moveable system, the movable system being a pusher charger machine (PCM) configured to charge a coke oven.

2. The system of claim 1 wherein the current is a direct current, and wherein the probe includes a wireless end portion configured to detect contact with the particulate, thereby causing a change in the direct current.

3. The system of claim 1 wherein the current is a direct current, and wherein the probe includes a wireless end portion configured to detect a collective charge associated with the particulate, thereby causing a change in the direct current.

4. The system of claim 1 wherein the current is an induced current, and wherein the probe includes a wireless end portion configured to detect a collective charge associated with the particulate, thereby causing a change in the induced current.

5. The system of claim 1 wherein the probe is configured to detect flow of the particulate.

6. The system of claim 1 , further comprising an operating system operably coupled to the detection device and configured to activate an indication.

7. The system of claim 1 wherein the separation or collection device includes at least one of a baghouse, a multiclone, or a dust collector.

8. The system of claim 1 wherein the detection device is one of a plurality of detection devices, wherein each of the detection devices is mounted to the PCM.

9. The system of claim 1 wherein the separation or collection device is a plurality of filters and the detection device is one of multiple detection devices, wherein each of the filters is positioned upstream of a corresponding one of the multiple detection devices.

10. A method for detecting particulate in an industrial gas facility, comprising:
positioning a detection device downstream of a separation or collection device configured to filter coal dust or coke dust from an industrial gas stream, wherein the separation or collection device and the detection device are positioned on a moveable pusher charger machine (PCM);
detecting particulate via a wireless probe of the detection device, the particulate including coal dust, coke dust, or a combination thereof; and
generating an action based on a current associated with the detected particulate being above a predetermined threshold.

11. The method of claim 10 wherein the wireless probe includes a sensing portion, and wherein detecting the particulate includes detecting a flow of the particulate via the sensing portion of the wireless probe.

12. The method of claim 11 wherein detecting the flow of particulate includes detecting contact between particulate and the sensing portion of the wireless probe, thereby causing a direct current associated with the wireless probe to exceed the predetermined threshold.

13. The method of claim 11 wherein the particulate has a collective charge, and wherein detecting the flow of particulate includes detecting at the sensing portion of the wireless probe the collective charge of the particulate, thereby causing a direct current associated with the wireless probe to exceed the predetermined threshold.

14. The method of claim 11 wherein detecting the flow or presence of particulate includes detecting at the sensing portion of the wireless probe a charge associated with the particulate, thereby causing an induced current associated with the probe to exceed the predetermined threshold.

15. The method of claim 10 wherein generating the action comprises activating an indication.

16. The method of claim 15 wherein the indication includes an audible alarm or an illuminated display.

17. A method for detecting particulate in an industrial gas facility, comprising:
positioning a detection device downstream of a separation or collection device configured to filter coal dust or coke dust from an industrial gas stream;
detecting particulate via a wireless probe of the detection device; and
generating an action based on a current associated with the detected particulate being above a predetermined threshold, wherein generating the action based on the current associated with the detected particulate includes de-energizing an output relay of the detection device to generate an indication.

18. The method of claim 17 wherein the wireless probe includes a sensing portion, and wherein detecting the particulate includes detecting a flow of the particulate via the sensing portion of the wireless probe.

19. The method of claim 18 wherein detecting the flow of particulate includes detecting contact between particulate and the sensing portion of the wireless probe, thereby causing a direct current associated with the wireless probe to exceed the predetermined threshold.

20. The method of claim 18 wherein the particulate has a collective charge, and wherein detecting the flow of particulate includes detecting at the sensing portion of the wireless probe the collective charge of the particulate, thereby causing a direct current associated with the wireless probe to exceed the predetermined threshold.
