Abstract
A vapor relief strainer cleaning assembly comprises a turbine and dislodger assembly, wherein the turbine is configured to move a dislodger assembly disposed within a vapor screen relief vessel. Exemplary dislodger assemblies are configured to be powered by vapor or gas and to use excess vapor or gas optionally to dislodge non-condensable contaminants from the filter screen or to facilitate contaminant dislodgement from the inner wall of the filter screen.
Claims14
A vapor relief strainer cleaning assembly comprising:
- a housing, wherein an inner wall of the housing defines a chamber;
- a filter screen disposed within the chamber, wherein the filter screen has an inner wall and an outer surface, and wherein the inner wall of the filter screen is configured to collect a fibrous non-condensable contaminant collected on the inner wall of the filter screen from vapor passing through the filter screen in a direction from the inner wall of the filter screen to the outer surface;
- a dislodger assembly disposed within the chamber, the dislodger assembly configured to clean at least a portion of the fibrous non-condensable contaminant collected on the inner wall of the filter screen, the dislodger assembly comprising:
- a shaft having a first axial end distally disposed from a second axial end;
- at least one dislodger support extending outwardly from the shaft, wherein the at least one dislodger support engages a dislodger, and wherein the dislodger is disposed adjacent to and in contact with the inner wall of the filter screen;
- and
- at least one discharge support extending outwardly from the shaft, wherein the at least one discharge support engages a discharge arm;
- and
- a lid assembly comprising:
- a turbine housing having walls, wherein the walls of the turbine housing define a turbine chamber, a turbine vapor inlet, a first turbine vapor outlet, and a second turbine vapor outlet, wherein the turbine chamber fluidly communicates with the turbine vapor inlet, the first turbine vapor outlet, and the second turbine vapor outlet;
- and
- a turbine comprising paddles extending outwardly from a turbine hub, wherein the turbine hub is a portion of the shaft extending into the turbine chamber, and wherein the turbine is configured to be disposed in the turbine housing,
- wherein the dislodger assembly is coupled to the shaft such that rotation of the turbine causes rotation of the dislodger assembly.
