Abstract
Abstract A distributor tube has tube slots in its shell surface transversely of the inflow direction of a fluid into the distributor tube. A casing tube is enclosed by the distributor tube and is divided into flow chambers, each of which is bounded by two annular plates and connected to an inlet sector. A star-shaped volume flow divider is located on the inlet side of the distributor tube as a tube insert, which divides the introduced mass flow rate into partial flow rates for the flow chambers. In another embodiment, the distributor tube encloses a rotationally symmetric pressure distributor, whereby the fluid within the distributor tube encounters equal pressure in the radial and axial flow directions over the inlet length of the distributor tube.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
124 words
A process for the uniform introduction of a fluid into a fluid bath by means of a distributor tube which is perforated over its shell surface, comprising the steps of: a) introducing a fluid stream into said distributor tube at one end side, b) guiding the fluid streams longitudinally in a gap between the distributor tube and a rotationally symmetrical pressure distributor, wherein the fluid pressure in the interior of said distributor tube is kept constant by an increasing diameter of said pressure distributor from said one end side to an end face of the distributor tube such that a uniform pressure distribution in the axial and radial flow directions is obtained in the fluid streams flowing through the gap in the distributor tube.
Claim 2
Dependent Claim
124 words
A process for the uniform introduction of a fluid into a fluid bath by means of a distributor tube which is perforated over its shell surface, comprising the steps of: a) introducing a fluid stream into said distributor tube at one end side, b) guiding the fluid streams longitudinally in a gap between the distributor tube and a rotationally symmetrical pressure distributor, wherein the fluid pressure in the interior of said distributor tube is kept constant by an increasing diameter of said pressure distributor from said one end side to an end face of the distributor tube such that a uniform pressure distribution in the axial and radial flow directions is obtained in the fluid streams flowing through the gap in the distributor tube.
Claim 3
Dependent Claim
27 words
A process as claimed in claim 1, wherein the fluid emerging from the perforated shell surface of said distributor has a uniform velocity and uniform internal pressure.
Claim 4
Dependent Claim
17 words
A process as claimed in claim 1, wherein said fluid stream comprises a liquid or a gas.
Claim 5
Dependent Claim
22 words
A process as claimed in claim 3, wherein said fluid stream comprises a liquid selected from the group consisting of electrolyte solutions.
Claim 6
Independent Claim
91 words
An apparatus for uniform distribution of a fluid into a fluid bath comprising a distributor tube perforated over its shell surface and enclosing thereby a rotationally symmetrical pressure distributor which is centered in the distributor tube by ribs in a star-shaped manner such that a gap is formed between an interior surface of the distributor tube and a shell surface of the pressure distributor, wherein the diameter of said pressure distributor increases from an inlet opening to an end face of the distributor tube, and is joined to said end face.
Claim 7
Independent Claim
91 words
An apparatus for uniform distribution of a fluid into a fluid bath comprising a distributor tube perforated over its shell surface and enclosing thereby a rotationally symmetrical pressure distributor which is centered in the distributor tube by ribs in a star-shaped manner such that a gap is formed between an interior surface of the distributor tube and a shell surface of the pressure distributor, wherein the diameter of said pressure distributor increases from an inlet opening to an end face of the distributor tube, and is joined to said end face.
Claim 8
Dependent Claim
48 words
An apparatus as claimed in claim 5, wherein the pressure distributor comprises a plurality of pressure distributor stages, wherein the pressure distributor stages are cylindrical and are connected together by frustroconical joints, and wherein the cylinder nearest to the inlet opening is occluded by a paraboloid of revolution.
Claim 9
Dependent Claim
42 words
An apparatus as claimed in claim 5, wherein the pressure distributor is designed such that the pressure distribution is isobaric in the inflowing fluid in the gap between the interior of the distributor tube and the shell surface of the pressure distributor.
Claim 10
Dependent Claim
88 words
An apparatus as claimed in claim 5, wherein the pressure distributor consists of a one-piece paraboloid of revolution, of which the internal diameter associated with a given length section k is determined by the equation d i 2 =d 0 2 +iD 2 /n, with the number n=L/k of the length sections k, and with a predetermined total length L, maximum internal diameter D, a predetermined length of a length section k of 10 mm, wherein the index i is an integer assuming values from 0 to n.
Claim 11
Dependent Claim
16 words
