Description
Die Erfindung betrifft eine Reinstwasserversorgungsanlage für wenigstens ein, vorzugsweise mehrere Dialysegeräte einer Dialysestation, mit einem Umkehrosmosegerät (RO-Gerät), das Reinstwasser bzw. Permeat einem Permeat-Verteilungssystem zuführt, das eine Primärleitung und wenigstens eine davon abgezweigte, einen Bypass bildende sekundäre Ringleitung aufweist, an die das wenigstens eine Dialysegerät angeschlossen ist. Durch die sekundäre Ringleitung wird dabei im Permeatzulauf der Permeatstrom aufgeteilt, wobei ein Teil weiter durch die Primärleitung – vorzugsweise eine Ringleitung – und der andere Teil durch die sekundäre Ringleitung fließt.The invention relates to an ultrapure water supply system for at least one, preferably several dialysis machines of a dialysis station, with a reverse osmosis device (RO unit), the ultrapure water or permeate feeds a permeate distribution system that a primary line and at least one secondary ring line branched therefrom to form a bypass to which the at least one dialysis machine is connected. By the secondary Ring line is divided in the permeate inlet, the permeate stream, a part further through the primary line - preferably a ring line - and the other part through the secondary Ring line flows.
Die Reinstwasserversorgung mittels Umkehrosmose bietet große Vorteile, da durch die Membranfiltration nahezu sämtliche anorganische Partikel, Kolloide und Keime sowie Endotoxine und Salze aus dem Rohwasser herausgefiltert werden. Ein großes Problem der Membranfiltration mittels Umkehrosmose liegt aber darin, daß sich bei zu geringer Fließgeschwindigkeit und erst recht bei einem Stillstand des Permeats im Permeat-Verteilungssystem Verunreinigungen bilden können, die zu einem Biofilmwachstum und einer Aufkeimung im Permeat führen. Dies tritt insbesondere bei nicht oder ungenügend durchströmten Abzweigungen und Toträumen im Permeat-Verteilungssystem und bei Stillstandszeiten des Dialysebetriebs auf, die mit ca. 6.000 Stunden pro Jahr zu veranschlagen sind.The purest water supply by means of Reverse osmosis offers great Advantages, because almost all of the membrane filtration inorganic particles, colloids and germs as well as endotoxins and salts be filtered out of the raw water. A big problem with membrane filtration by means of reverse osmosis is that if the flow rate is too low and especially when the permeate in the permeate distribution system comes to a standstill can form which lead to biofilm growth and germination in the permeate. This occurs in particular when branches are not or insufficiently flowed and dead dreams in Permeate distribution system and when the dialysis is at a standstill which are estimated to be around 6,000 hours a year.
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Reinstwasserversorungsanlage der betrachteten Art so weiter zu entwickeln, daß Verunreinigungen in dem Permeat weitestgehend vermieden sind, wobei die Installationskosten der Anlage kleiner sein sollen.The present invention lies based on the task of a ultrapure water supply system of the considered Way to develop so that impurities in the permeate are largely avoided, the installation costs the system should be smaller.
Diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst.This task through the characteristics of claim 1 solved.
Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen gekennzeichnet.Advantageous embodiments of the Invention are in the dependent claims characterized.
Die Erfindung sieht vor, daß die wenigstens eine sekundäre Ringleitung mit ihrem stromaufwärtigen Endabschnitt innerhalb der Primärleitung angeordnet ist und dann durch die Wand der Primärleitung aus dieser austritt, wobei das zugeordnete Dialysegerät an den außerhalb der Primärleitung verlaufenden Abschnitt der sekundären Ringleitung angeschlossen ist. Die sekundäre Ringleitung mündet danach mit ihrem stromabwärtigen Endabschnitt wieder in die Primärleitung ein.The invention provides that the at least one secondary Ring line with its upstream End section within the primary line is arranged and then emerges through the wall of the primary line, being the associated dialysis machine to the outside the primary line extending section of the secondary ring line connected is. The secondary Ring line opens afterwards with their downstream End section back into the primary line on.
Die Primärleitung wird beim Dialysebetrieb ständig von einem Permeatstrom durchströmt. Da die sekundäre Ringleitung, die die Entnahmestelle des Dialysegerätes mit der Primärleitung verbindet, mit ihrem stromaufwärtigen Endabschnitt, also dem Einlaufbereich, innerhalb der Primärleitung angeordnet ist, strömt das Permeat infolge der Strömungsverhältnisse in die sekundäre Ringleitung ein, so daß diese auch bei diskontinuierlicher Entnahme des Permeats durch das Dialysegerät ständig hinreichend durchströmt wird, so daß eine Aufkeimung des dem Dialysegerät zugeführten Permeats sicher vermieden ist. Mit ihrem stromabwärtigen Endabschnitt mündet die sekundäre Ringleitung wieder in die Primärleitung ein.The primary line is constantly on during dialysis flows through a permeate stream. Because the secondary Ring line with the removal point of the dialysis machine the primary line connects with her upstream End section, i.e. the inlet area, within the primary line is arranged, flows the permeate due to the flow conditions into the secondary Ring line so that this the dialysis machine continuously provides sufficient flow even when the permeate is removed intermittently, so that a germination of the dialysis machine supplied Permeates are safely avoided. With its downstream end section, the secondary Ring line back into the primary line on.
Dabei ist bevorzugt, daß der stromaufwärtige Endabschnitt der sekundären Ringleitung konzentrisch in der Primärleitung angeordnet ist, d.h. in dem zentralen Bereich, in dem das Permeat am schnellsten fließt.It is preferred that the upstream end section the secondary Loop is arranged concentrically in the primary line, i.e. in the central area where the permeate flows fastest.
Weiter wird mit Vorteil vorgeschlagen, daß der stromaufwärtige Endabschnitt der sekundären Ringleitung geradlinig verläuft und im Bereich einer Krümmung der Primärleitung aus dieser austritt. Auch hierdurch wird der Strömungswiderstand in der sekundären Ringleitung so klein wie möglich gehalten. Wenn die Primärleitung geradlinig verläuft, tritt die sekundäre Ringleitung mit einem bogenförmigen Abschnitt aus der Primärleitung aus.It is also proposed with advantage that the upstream End section of the secondary ring line runs straight and in the area of a curve the primary line exits from this. This also makes the flow resistance in the secondary ring line as small as possible held. If the primary line runs straight, enters the secondary Ring line with an arcuate section from the primary line out.
In weiteren Einzelheiten wird vorgeschlagen, daß die sekundäre Ringleitung in dem Bereich wieder in die Primärleitung einmündet, in dem sich ihr stromaufwärtiger Endabschnitt innerhalb der Primärleitung befindet. Dabei kann das stromabwärtige Ende der sekundären Ringleitung bündig mit der Wand der Primärleitung abschließen, d.h. die sekundäre Ringleitung steht dabei nicht ins Innere der Primärleitung vor.In more detail, it is proposed that the secondary ring line flows into the primary line in the area, in which you are upstream End section is located within the primary line. The downstream End of secondary Ring line flush with the wall of the primary line to lock, i.e. the secondary The ring line does not protrude into the interior of the primary line.
In einer alternativen Ausgestaltung ist vorgesehen, daß die sekundäre Ringleitung stromabwärts ihres Austritts aus der Primärleitung wieder in diese einmündet. Auch hierbei kann der Eintritt als bündiger Anschluß an die Wand der Primärleitung erfolgen, oder – was hier bevorzugt ist – die sekundäre Ringleitung erstreckt sich mit ihrem stromabwärtigen Endabschnitt in die Primärleitung hinein. Dabei kann die Anordnung so erfolgen, daß die Mittellängsachse der sekundären Ringleitung entweder mit der Mittellängsachse der Primärleitung zusammenfällt oder aber mit dieser fluchtet. Die sekundäre Ringleitung kann aber auch außermittig oder im rechten Winkel in die Primärleitung einmünden.In an alternative embodiment it is provided that the secondary ring line flows back into the primary line downstream of its exit from the primary line. Here, too, the entry can be made as a flush connection to the wall of the primary line, or — which is preferred here — the secondary ring line extends downstream End section into the primary line. The arrangement can be such that the central longitudinal axis of the secondary ring line either coincides with the central longitudinal axis of the primary line or is flush with it. However, the secondary ring line can also lead off-center or at a right angle into the primary line.
Durch die erfindungsgemäße Rohr-in-Rohr-Anordnung des Einlaufbereichs der sekundären Ringleitung in der Primärleitung ist sichergestellt, daß die sekundäre Ringleitung – ebenso wie die Primärleitung – während des Dialysebetriebs ständig von einem Permeatstrom durchspült wird, so daß sich keine Verunreinigungen in den Leitungen bilden können.Through the tube-in-tube arrangement according to the invention the entry area of the secondary Ring line in the primary line it is ensured that the secondary Ring line - as well like the primary line - during the Dialysis operation constantly flushed by a stream of permeate will, so that cannot form impurities in the lines.
