Abstract
Abstract A baffling and flow distribution apparatus for use in a system in which a fluid is desired to be passed from one bed of particles to another bed of particles with addition or withdrawal of fluids between the beds at a location within a baffling and flow distribution apparatus which itself is located between the beds. The invention includes two substantially parallel solids retaining screens which are spaced apart and which contain ribs between said screens which radiate from a central support hub. The screens also have placed between them a fluid deflection plate which has a passage in it and which has placed near the passage a fluid transfer means which can allow fluid when passing from one bed through the screens, through the passage through the other screen and into another bed, to pass by said transfer means so fluid may be added or removed from the apparatus. The above apparatus allows placement of the fluid transfer means within the apparatus at a position which can improve the flow characteristics of fluid materials passing from one bed through the opening into another bed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
228 words
A baffling and flow distribution apparatus located between two beds of solid particles having a common axis and an outer edge radially located from said axis comprising: a. two substantially parallel solids retaining screens spaced apart; b. ribs located between said screens and attached to a central support hub and radiating from said central support hub, said hub axially aligned with said axis of said beds, with said ribs extending to the outer edges of said beds to form a plurality of segment volumes between said screens and ribs; c. each segment volume containing fluid deflection plate means located between said screens, radiating from said support hub to the outer edge of said beds, said plate means connected to said ribs to separate said segment volume into two compartments; d. said deflection plate means having a passage connecting said compartments within said segment volume and located between said support hub and the outer edge of said beds along said plate means; e. a fluid transfer means located adjacent to said passage and connected to a fluid transfer conduit to effect the pAssage of fluid between said conduit and said passage within said segment volume; and f. said deflection plate means having decreasing overall thickness when proceeding along said plate means from said support hub to said passage and from the outer edge of said beds to said passage.
Claim 2
Dependent Claim
228 words
A baffling and flow distribution apparatus located between two beds of solid particles having a common axis and an outer edge radially located from said axis comprising: a. two substantially parallel solids retaining screens spaced apart; b. ribs located between said screens and attached to a central support hub and radiating from said central support hub, said hub axially aligned with said axis of said beds, with said ribs extending to the outer edges of said beds to form a plurality of segment volumes between said screens and ribs; c. each segment volume containing fluid deflection plate means located between said screens, radiating from said support hub to the outer edge of said beds, said plate means connected to said ribs to separate said segment volume into two compartments; d. said deflection plate means having a passage connecting said compartments within said segment volume and located between said support hub and the outer edge of said beds along said plate means; e. a fluid transfer means located adjacent to said passage and connected to a fluid transfer conduit to effect the pAssage of fluid between said conduit and said passage within said segment volume; and f. said deflection plate means having decreasing overall thickness when proceeding along said plate means from said support hub to said passage and from the outer edge of said beds to said passage.
Claim 3
Dependent Claim
20 words
Claim 1 in that a portion of said fluid transfer means is located within the passage in said plate means.
Claim 4
Dependent Claim
207 words
A baffling and flow distribution apparatus located between two solid particle beds, said beds confined within an elongated column, said column and beds having a common longitudinal axis, comprising: a. two substantially parallel solids retaining screens spaced apart and positioned substantially perpendicular to said axis; b. a central hub axially aligned with said axis; c. ribs, located between said screens and connected thereto, connected to said hub and radiating from said hub outwardly extending to said column to form a plurality of segment volumes between said screens; d. fluid deflection plate means located between said solids retaining screens and positioned substantially perpendicular to said axis, said plate means attached to said hub and projecting outwardly from said hub and attached to said column, said plate means attached to said ribs thereby separating each segment volume into two compartments; e. passage means located in said plate means connecting said compartments and having placed adjacent to said passage means fluid transfer means to effect the passage of fluid between said passage means and said transfer means; and, f. said deflection plate means having a decreasing overall thickness when proceeding along said plate means from said support hub to said passage means and from said column to said passage means.
Claim 5
Dependent Claim
207 words
A baffling and flow distribution apparatus located between two solid particle beds, said beds confined within an elongated column, said column and beds having a common longitudinal axis, comprising: a. two substantially parallel solids retaining screens spaced apart and positioned substantially perpendicular to said axis; b. a central hub axially aligned with said axis; c. ribs, located between said screens and connected thereto, connected to said hub and radiating from said hub outwardly extending to said column to form a plurality of segment volumes between said screens; d. fluid deflection plate means located between said solids retaining screens and positioned substantially perpendicular to said axis, said plate means attached to said hub and projecting outwardly from said hub and attached to said column, said plate means attached to said ribs thereby separating each segment volume into two compartments; e. passage means located in said plate means connecting said compartments and having placed adjacent to said passage means fluid transfer means to effect the passage of fluid between said passage means and said transfer means; and, f. said deflection plate means having a decreasing overall thickness when proceeding along said plate means from said support hub to said passage means and from said column to said passage means.
Claim 6
Dependent Claim
21 words
Claim 3 in that said passage located in said deflection plate means is positioned between said support hub and said column.
Claim 7
Dependent Claim
37 words
Claim 4 in that the ratio of the distance of said passage means from said hub to the distance of said passage means from said column is within the range of from about 2.9 to about 1.3.
