Abstract
A baffle comprises an outer ring suitable for surrounding a plurality of parallel tubes formed into a tube bundle, said tube bundle having at least a first plurality of parallel tube rows, a second plurality of parallel tube rows, and spaces between the adjacent tube rows, said outer ring positioned in a plane which is not perpendicular to the longitudinal axis of the tube bundle, said plane forming a baffle angle with a plane which is perpendicular to the longitudinal axis of the tube bundle, and a plurality of parallel rods cooperating with and attached to the outer ring to form a plurality of parallel chords with the outer ring wherein the rods are capable of passing in the spaces between the tubes forming adjacent parallel tube rows of one plurality of parallel tube rows.
Claims20
Supporting apparatus for a plurality of tubes in the form of a tube bundle suitable for use in a shell and tube heat exchanger, said tubes positioned to form at least a first plurality of parallel tube rows and a second plurality of parallel tube rows and spaces between at least a portion of the adjacent tube rows comprising:
- at least one baffle set providing radial support for each tube and comprising two baffles, wherein each baffle is positioned along the length of the tube bundle a distance relative to the other baffle of the baffle set and wherein each baffle comprises
- an outer ring surrounding said tube bundle positioned in a plane which is not perpendicular to the longitudinal axis of said tube bundle, said plane forming a baffle angle with a plane which is perpendicular to the longitudinal axis of the tube bundle;
- and
- a plurality of rods positioned in all of the spaces between adjacent tube rows in one plurality of parallel tube rows so that one rod is positioned in each space, said plurality of rods cooperating with said outer ring to form a plurality of parallel chords with said outer ring, and each said rod being of sufficient size to provide support for the tubes in the tube rows adjacent said rod.
Apparatus comprising:
- a plurality of tubes forming a tube bundle suitable for use in a shell and tube heat exchanger, said tubes positioned to form at least a first plurality of parallel tube rows and a second plurality of parallel tube rows and spaces between at least a portion of the adjacent tube rows;
- means supporting the ends of said tube bundle;
- and
- intermediate means supporting the tubes in the tube bundle intermediate their ends, said intermediate supporting means comprising
- at least one baffle set, each baffle set providing radial support for each tube and comprising two baffles wherein each baffle is positioned along the length of the tube bundle a distance relative to the other baffle of the baffle set and wherein each baffle comprises
- an outer ring surrounding said tube bundle and positioned in a plane which is not perpendicular to the longitudinal axis of said tube bundle, said plane forming a baffle angle with a plane which is perpendicular to the longitudinal axis of the tube bundle;
- and
- a plurality of rods positioned in all of the spaces between adjacent tube rows in one plurality of parallel tube rows so that one rod is positioned in each space, said plurality of rods being attached to said outer ring and forming a series of parallel chords with said outer ring, said rods being of sufficient size to provide support for the tubes in the tube rows adjacent each rod.
