Cartridge type vortex suppression device
View Patent ↗A vortex suppression device is provided which includes a plurality of spaced apart porous panels arranged generally parallel with respect to each other for placement adjacent a suction pipe inlet. The panels of the suppression device are oriented generally perpendicular to, or parallel to the suction pipe inlet. The device serves to prevent formation of a sufficiently strong vortex capable of pulling a continuous gas core into the suction piping.
1. A vortex suppression device comprising:
a plurality of spaced apart generally parallel panels, each panel having a plurality of pores formed therein and spaced vertically and horizontally within each panel, each panel being structured to be disposed adjacent a pipe inlet or outlet,
wherein the pipe inlet or outlet is disposed generally in a plane,
wherein each panel is structured to be oriented generally perpendicular to the plane, and
wherein the plurality of spaced apart generally parallel panels comprises two spaced apart panels, each panel being a respective portion of a single, continuous sheet of a perforated material.
2. The vortex suppression device of claim 1 , wherein at least one of the panels is structured to be disposed across the pipe inlet or outlet.
3. The vortex suppression device of claim 1 , wherein the plurality of pores comprise a total area of at least 25% of the panel surface area.
4. The vortex suppression device of claim 1 , wherein the perforated material is stainless steel, or another metal.
5. The vortex suppression device of claim 1 , wherein each panel comprises a mesh fabricated of fiberglass.
6. A liquid handling system comprising:
a vessel, at least partially enclosed, capable of holding a liquid;
an outlet opening in the vessel from which a flow of the liquid may exit the vessel;
a vortex suppression device in close proximity to the outlet comprising a plurality of spaced apart generally parallel panels, each panel having a plurality of pores formed therein and spaced vertically and horizontally within each panel,
wherein at least one of the panels is disposed across the outlet opening.
7. The liquid handling system of claim 6 , wherein the plurality of spaced apart generally parallel panels is structured together in pairs, each pair forming a module.
8. The liquid handling system of claim 7 , wherein the spacing between panels of a module is generally equal to the spacing between modules.
9. The liquid handling system of claim 7 , wherein the vortex suppression device is situated generally above the outlet opening and the modules extend beyond the perimeter of the outlet opening.
10. The liquid handing system of claim 6 , wherein the vortex suppression device is rigidly secured via a mounting frame.
11. The liquid handling system of claim 10 , wherein the vortex suppression device and mounting frame is constructed of a stainless steel material, or another metal.
12. The liquid handling system of claim 6 wherein the outlet opening is disposed generally in an outlet plane, and wherein each panel is disposed generally perpendicular to the outlet plane.
13. A method of suppressing a vortex in a liquid handling system comprising a vessel, at least partially enclosed, holding a liquid, the vessel having an outlet opening from which a flow of the liquid may exit the vessel, the method comprising:
securing a vortex suppression device to the vessel about the outlet opening,
wherein the vortex suppression device comprises a plurality of spaced apart generally parallel porous panels, each panel having a plurality of pores formed therein and spaced vertically and horizontally within each panel,
and wherein securing the vortex suppression device comprises securing the device such that an edge of at least one of the panels is disposed across the outlet opening.
14. The method of claim 13 wherein the outlet opening is disposed generally in a plane, and wherein securing the vortex suppression device further comprises securing each panel of the plurality of panels generally perpendicular to the plane of the outlet opening.
15. The method of claim 13 further comprising securing the plurality of spaced apart generally parallel porous panels of the vortex suppression device together in a spatial relationship via a structural mounting frame prior to securing the vortex suppression device to the vessel.
16. The method of claim 13 wherein the plurality of spaced apart generally parallel panels comprises two spaced apart panels, and wherein the method further comprises forming each panel from a respective portion of a single, continuous sheet of a perforated material by bending the continuous sheet in a manner such that a first portion of the continuous panel is disposed generally parallel to a second portion of the continuous panel.
