Abstract
A screen for use in distributing a fluid in a process flow system. The screen provides support, and provides for the ability to clean particulates from the screen. The screen includes profiled wires affixed to a support, where the support provides channels to distribute the fluid over the screen. The support includes spacing to improve the cleaning of particulates from the screen.
Claims16
A screen assembly for collecting and distributing a process flow stream comprising:
- a plurality of wires spaced apart in a substantially parallel orientation and fixedly mounted to a support relative to each other and forming a screen, wherein the spaces define slots between neighboring wires for the passage of a fluid, and where the screen has a total slot open area;
- and
- a plurality of angled rods, having a generally L shaped configuration, with a first edge at one end of the L shape and a second edge at the other end of the L shape, where the first edge is affixed to the plurality of wires in a substantially perpendicular orientation relative to the wires and providing the support, and the angled rods form a partially covered channel on one side of the screen with the second edge of the angled rods spaced apart from a neighboring angled rod to form a channel gap with the sum of the gap areas forming the total channel gap area, and where the total channel gap area is greater than the total slot open area.
