Abstract

A pulse jet cleaning system is disclosed having at least one diverter device and having at least one control valve configured for receiving pulse air from a pulse air manifold and controllably passing a pulse of pulse air downstream to clean the filter assemblies. The at least one diverter is configured for receiving the pulse from the control valve and diverting the pulse into a plurality of outlet ports for providing pulse air to at least two blowpipes for cleaning a filter assembly.

First claim

What is claimed is:

1. A diverter device for pulse jet cleaning comprising,
a control valve configured for receiving pulse air from a pulse air manifold and controllably passing a pulse of pulse air downstream, and
at least one diverter configured for receiving the pulse from the control valve and diverting the pulse into a plurality of outlet ports for providing pulse air to at least two blowpipes for cleaning a filter assembly,
wherein the diverter further comprises,
a housing defining a diverter chamber, the diverter chamber having a pulse air inlet and a plurality of pulse air outlets,
a movable plug positioned in a first position within a first pulse air outlet, the plug defining an aperture for selectively controlling pulse air flow through the chamber and into one of the pulse air outlets, the plug movable between the first position and a second position within a second pulse air outlet, and
at least one pilot line extending from the diverter to at least one of a first blowpipe and a second blowpipe, the pilot line configured to deliver a portion of the pulse to the diverter for passively moving the plug between the first and second position.

2. The diverter device of claim 1 , further comprising a biasing element configured to urge the plug into the first position absent a pulse.

3. The diverter device of claim 2 , wherein the biasing element comprises a spring.

4. The diverter device of claim 1 , wherein the control valve is selected from at least one of the group consisting of solenoid valve and diaphragm valve.

5. The diverter device of claim 1 , wherein the control valve is actuated by at least one of the group consisting of electrical signal, hydraulic signal and pneumatic signal.

6. The diverter device of claim 1 , wherein the movable plug is selected from at least one the group consisting of flapper and ball.

7. The diverter device of claim 1 , wherein the diverter comprises a multi-way diverting valve.

8. The diverter device of claim 7 , wherein the multi-way diverting valve is actively operated by at least one of the group consisting of electrical signal, hydraulic signal and pneumatic signal.

9. The diverter device of claim 1 , further comprising a controller to sequentially operate the at least one diverter in response to an airside pressure drop across the filter assembly.

10. A pulse jet filter cleaning system comprising,
a filter chamber comprising, a pulse air manifold,
a plurality of control valves configured for receiving pulse air from the pulse air manifold and controllably passing a pulse of pulse air downstream, and
at least one diverter configured for receiving the pulse from one of the control valves and diverting the pulse into a plurality of outlet ports for providing pulse air to at least two blowpipes for cleaning a filter assembly,
wherein the diverter further comprises,
a housing defining a diverter chamber, the diverter chamber having a pulse air inlet and a plurality of pulse air outlets,
a movable plug positioned in a first position within a first pulse air outlet, the plug defining an aperture for selectively controlling pulse air flow through the chamber and into one of the pulse air outlets, the plug movable between the first position and a second position within a second pulse air outlet, and
at least one pilot line extending from the diverter to at least one of a first blowpipe and a second blowpipe, the pilot line configured to deliver a portion of the pulse to the diverter for passively moving the plug between the first and second position.

11. The cleaning system of claim 10 , further comprising a biasing element configured to urge the plug into the first position absent a pulse.

12. The cleaning system of claim 11 , wherein the biasing element comprises a spring.

13. The cleaning system of claim 10 , wherein the plurality of control valves is selected from least one of the group consisting of solenoid valve and diaphragm valve.

14. The cleaning system of claim 10 , wherein the plurality of control valves are actuated by at least one of the group consisting of electrical signal, hydraulic signal and pneumatic signal.

15. The cleaning system of claim 10 , wherein the movable plug is selected from at least one the group consisting of flapper and ball.

16. The cleaning system of claim 10 , wherein the diverter comprises a multi-way diverting valve.

17. The cleaning system of claim 16 , wherein the multi-way diverting valve is actively operated by at least one of the group consisting of electrical signal, hydraulic signal and pneumatic signal.

18. The cleaning system of claim 10 , further comprising a controller to sequentially operate the at least one diverter in response to an airside pressure drop across the filter assembly.
