Abstract

The Parent Patent described an appts. for de-acidifying liquids comprising stacks of units each consisting of a distributor plate with inlet and overflow and a semipermeable membrane consisting of two porous discs with a drainage fabric between them, leading to a discharge duct. In this patent instead of 2 discs and a drainage fabric, each plate unit comprises a single disc of porous sintered stainless steel, surrounded by a ring having a drainage groove in its inner periphery and a discharge duct leading from the groove out through the ring.

Description

Die poröse Stützscheibe2 aus gesintertem Edelstahl wird ringsherum von einem Ring 1 aus Edelstahl fest umschlossen, in dessen inneren Rand radial eine Nut 3 eingearbeitet ist. Das Filtrat fließt bei dieser Anordnung durch die poröse Stützschicht der Scheibe nach außen, wo es sich in der umlaufenden Nut 3 des Stahlringes 1 sammelt und über ein Ausflußrohr 4 praktisch drucklos abfließt. The porous support disc2 made of sintered stainless steel is all around firmly enclosed by a ring 1 made of stainless steel, in the inner edge of which a radial Groove 3 is incorporated. With this arrangement, the filtrate flows through the porous Support layer of the disc to the outside, where it is in the circumferential groove 3 of the steel ring 1 collects and flows through an outlet pipe 4 practically without pressure.

Patentanspruch: Vorrichtung zur Durchführung des Verfahrens zum Entsäuern von Flüssigkeiten unter Verwendung von Einheiten oder Stapeln von Einheiten einer semipermeablen Membran mit einer Stützvorrichtung, bestehend aus einer Verteilerplatte mit Zulauf, zwei Kanälen und einem überlauf, sowie einer semipermeablen Membran mit zwei porösen Stützscheiben mit einem dazwischen angeordneten Drainagegewebe mit Ausflußkanal nach Patentanmeldung P 2050917.5-24, d a -durch gekennzeichnet, daß an Stelle von zwei porösen Stützscheiben mit dem dazwischen angeordneten Drainagegewebe für jedes Plattenaggregat nur eine poröse Stützscheibe (2) aus gesintertem Edelstahl eingesetzt ist, die ringsherum von einem Ring (1) fest umschlossen ist, in dessen inneren Rand eine Nut (3) eingearbeitet ist, von der ein Abflußrohr (4) durch den Ring (1) nach außen führt. Claim: Device for carrying out the deacidification process of liquids using units or stacks of units one semipermeable membrane with a support device consisting of a distributor plate with inlet, two channels and an overflow, as well as a semipermeable membrane with two porous support disks with a drainage fabric in between with outflow channel according to patent application P 2050917.5-24, d a -marked by, that instead of two porous support disks with the drainage fabric arranged in between only one porous support disc (2) made of sintered stainless steel for each plate unit is used, which is firmly enclosed all around by a ring (1), in which inner edge a groove (3) is incorporated from which a drain pipe (4) through the Ring (1) leads to the outside. Gegenstand der Hauptanmeldung P 2 050 917.5-24 ist außer einem Verfahren zur Verminderung des Säuregehaltes von wäßrigen Flüssigkeiten eine Vorrichtung zur Durchführung dieses Verfahrens unter Verwendung von Einheiten oder Stapeln von Einheiten einer semipermeablen Membran mit einer Stützvorrichtung, die dadurch gekennzeichnet ist, daß ein Plattenaggregat verwendet wird, welches besteht aus einer Verteilerplatte mit Zulauf, Kanälen und Überlauf, sowie einer semipermeablen Membran mit zwei porösen Stützscheiben, zwischen denen ein Drainagegewebe angeordnet ist, dessen Kanäle in einen Ausflußkanal für das Filtrat münden. The subject of the main application P 2 050 917.5-24 is apart from a method a device for reducing the acidity of aqueous liquids Perform this procedure using units or stacks of units a semipermeable membrane with a supporting device, which is characterized is that a plate unit is used, which consists of a distributor plate with inlet, channels and overflow, as well as a semipermeable membrane with two porous ones Support disks, between which a drainage tissue is arranged, the channels of which are in open an outflow channel for the filtrate. Die in dieser Vorrichtung verwendeten porösen Stützscheiben sind in der Hauptanmeldung nicht besonders beschrieben, da es bekannt ist, daß zur Unterstützung von Membranen durchlässige Werkstoffe, unter anderem auch in Form von Stützscheiben aus Geweben von Textilien, Kunststoffen und Metalldrähten, ferner aus Textil- und Kunststoff-Fasern, aus gesinterten Kunststoffen und aus Keramik, verwendet werden. The porous support disks used in this device are not specifically described in the parent application as it is known to assist Materials permeable by membranes, including in the form of support disks made of fabrics of textiles, plastics and metal wires, also made of textile and Plastic fibers, made from sintered plastics and made from ceramics, can be used. Es ist schwierig, für die Verwendung in Vorrichtungen, in denen hohe Drücke angewendet werden, wie das bei der umgekehrten Osmose oft notwendig ist, geeignete Materialien für die erforderliche Unterstützung der Membranen zu finden, die den hohen Drücken standhalten, ohne sich zu verformen. It is difficult for use in devices where high Pressures are applied, as is often necessary in reverse osmosis, to find suitable materials for the necessary support of the membranes, that withstand the high pressures without deforming. Der Erfindung liegt die Aufgabe zugrunde, bei der Vorrichtung nach der Hauptanmeldung poröse Stützscheiben von einer Beschaffenheit und Gestaltung einzusetzen, die den höchsten für die Durchführung des genannten Verfahrens vorkommenden Drücken standhalten, ohne sich zu verformen oder sonstwie zu verändern. The invention is based on the object of the device of the main application porous support disks of one nature and design to use the highest that occurs for the implementation of the named procedure Withstand pressure without deforming or otherwise changing. Das wird erfindungsgemäß dadurch erreicht, daß in der Vorrichtung der Hauptanmeldung zur Unterstützung der semipermeablen Membranen an Stelle von zwei porösen Scheiben mit Drainagegewebe nur eine poröse Stützscheibe aus gesintertem Edelstahl eingesetzt ist, die von einem Ring mit Innennut und Abflußrohr umschlossen ist. Die Schicht aus gesintertem Stahl beträgt zweckmäßig etwa 3 bis 8 mm. This is achieved according to the invention in that in the device of the main application to support the semipermeable membranes in place of two porous discs with drainage fabric only one porous support disc made of sintered Stainless steel is used, which is enclosed by a ring with an inner groove and drain pipe is. The layer of sintered steel is expediently about 3 to 8 mm. Es können auch andere Sintermetalle verwendet werden, soweit sie gegenüber der zu behandelnden Flüssigkeit inert sind; jedoch hat sich gesinterter Edelstahl als am besten geeignet erwiesen. Other sintered metals can also be used as far as they are are inert to the liquid to be treated; however, it has become sintered Stainless steel proved to be the most suitable. Die Verwendung von Stützscheiben aus gesintertem Edelstahl hat noch den weiteren besonderen Vorteil, daß der Abfluß des Filtrats nunmehr viel einfacher angeordnet werden kann, wie aus der Zeichnung und den Erläuterungen dazu erkenntlich ist. The use of support disks made of sintered stainless steel still has the further special advantage that the outflow of the filtrate is now much easier can be arranged, as can be seen from the drawing and the explanations is. Fig.1 ist eine Draufsicht auf die erfindungsgemäße poröse Stützscheibe; F i g. 2 zeigt einen Schnitt durch die Mitte der Stützscheibe. Fig. 1 is a top plan view of the porous support disk of the present invention; F i g. 2 shows a section through the center of the support disc.
