PROBLEM TO BE SOLVED: To prevent a vortex from being generated in fluid exiting in a vessel.SOLUTION: A vortex breaker 100, which fits over an outlet of a vessel, has a basket 110 disposed on a base with an opening communicating with the vessel's outlet. The basket has a cylindrical sidewall screen with multiple profiled wires arranged around bars that extend from the base. The basket also has a top screen attached to the sidewall screen. The top screen has multiple wires arranged across multiple bars. Below the top screen, a baffle plate diverts the fluid flow passing through the top screen to the periphery of the top plate. Inside the basket, a flow modifier has multiple vanes 170, 180 attached to the base and disposed radially around the base's opening. At least some of the vanes 180 have cross-tees 182 extending from the vane's sides to break the radially directed flow inside the basket. |
