Abstract

A fluid distributor/collector assembly is composed of a screen cylinder, a perforated tube provided in the screen cylinder and support discs also provided in the screen cylinder. The screen cylinder is made of cylindrically arranged support rods and a wire screen wound helically on the support rods. The perforated tube is formed with apertures for distributing or collecting fluid which flows through the wire screen. The support discs radially support the screen cylinder outwardly from the perforated tube thereby defining a space between the screen cylinder and the perforated tube. Within each support disc is an opening in which the perforated tube is supported. The assembly can be buried in a catalyst bed within a catalytic reactor and used to distribute or collect fluid.

Claims

1. A fluid distributor/collector assembly comprising:

a screen cylinder composed of a plurality of elongated support rods arranged cylindrically spaced apart with a suitable distance between adjacent rods and a wire screen member wound helically on said cylindrically arranged support rods;

at least one tube disposed within said screen cylinder and formed with a multiplicity of apertures for distributing or collecting fluid which flows through said wire screen member of said screen cylinder;

a plurality of support discs, each having an outer periphery, provided within said screen cylinder said support discs being positioned spaced apart along the axis of said screen cylinder in such a manner that said support rods of said screen cylinder are supported on the outer periphery of said support discs, each of said support discs having at least one tube opening in which said at least one tube is positioned thereby supporting said at least one tube within said screen cylinder in such a manner that a space is defined between said tube and said wire screen member of said screen cylinder;

each adjacent pair of support discs setting-off therebetween a portion of said at least one tube and defining space sections within said space between said at least one tube and said screen cylinder;

all of said tube portions having flow apertures therein;

flow communication means in each of said support discs for permitting fluid to flow between adjacent space sections; and

pipe means connected to said at least one tube for supplying fluid to be distributed to said at least one tube or for removing fluid that has collected within said at least one tube.

2. A fluid distributor/collector assembly as defined in claim 1 wherein said support discs are formed with a pair of slits in diametrically opposed positions in said support discs and which further comprises a pair of support beams which are fitted into said slits of said support discs to connect said support discs together.

3. A fluid distributor/collector assembly as defined in claim 1 wherein each of said support discs are formed with a plurality of said tube openings and a plurality of said tubes, and wherein each tube opening has only one tube supported therein.

4. The fluid distributor/collector assembly as defined in claim 1 wherein said flow communication means comprises at least one opening through each support disc.

5. A fluid distributor/collector assembly comprising:

at least one elongated tube;

a plurality of aperture means along said at least one elongated tube for distributing or collecting fluid therethrough;

means defining a screen of a generally cylindrical configuration, said screen means being in external substantially radially spaced relationship to said at least one elongated tube thereby defining an annular longitudinally extending chamber between said screen means and said at least one elongated tube through which a fluid may flow;

a plurality of support means spaced a predetermined distance from each other axially along said at least one elongated tube and between said at least one elongated tube and said screen means for supporting said screen means in said radially spaced relationship, said support means being a plurality of support discs with adjacent support discs setting-off therebetween a portion of said at least one elongated tube and dividing said chamber into sections, all of said tube portions having flow apertures therein;

flow communication means in each of said support discs for permitting fluid to flow between adjacent chamber sections; and

pipe means connected to said at least one elongated tube for supplying a fluid to be distributed to said at least one elongated tube or for removing fluid that has collected within said at least one elongated tube.

6. The fluid distributor/collector assembly as defined in claim 5 wherein said flow communication means comprises at lease one opening through each support disc.

7. The fluid distributor/collector assembly as defined in claim 5 wherein each of said support discs has at least one tube opening and an outer periphery, said at least one elongated tube being supported within said at least one tube opening, and each support disc being secured at its outer periphery to said screen means.

8. The fluid distributor/collector assembly as defined in claim 7 wherein each of said support discs has a plurality of said tube openings and plurality of said elongated tubes, and wherein each tube opening has only one elongated tube supported therein.
