Description

Die Erfindung bezieht sich auf ein Verfahren zur Neutralisation des in GefäßreiniguKgsmaschinen anfallenden Abwassers, bei welchem die zu behandelnde Flüssigkeit mittels CO2 beaufschlagt wird.The invention relates to a method for neutralizing the waste water that occurs in vessel cleaning machines, in which the waste water to be treated Liquid is acted upon by CO2.

Die in den letzten Jahren erheblich verschärften Bestimmungen zum Schutz der Gewässer zwingen die Getränkebetriebe, verbrauchte Abwasser nicht mehr wie bisher unmittelbar in d';e Kan !isation abzuleiten, sondern diese vorher in ertsprechender Weise zu behandeln. Ein naheliegendes Verfaß jn zur Erfüllung der eingangs genannten Auflagen stellt die Neutralisation des anfallenden Abwassers dar. Dieser Neutralisation muß allerdings aufgrund der Einleitungsanforderungen eine Abkühlung auf 35° C durch Zwischenlagerung oder durch Wärmeaustausch vorausgehen. Die chemische Reaktion ist dahingehend definiert, daß die für die Säurereaktion einer Lösung verantwortlichen H-* (bzw. H3O+)-lonen mit den die basische Reaktion verursachenden OH--Ionen reagieren und sich zu neutralem Wasser zusammenlagern, sobald Lauge mit Säure zusammengebracht wird. Für die Neutralisation der verbrauchten Reinigungslauge von Gcfäßbehandlungsmaschinen wäre die Behandlung mit Schwefelsäure, Salzsäure usw. denkbar, wobei die Verwendung von Schwefelsäure aus abwassertechnischen Gründen nicht zum Einsatz kommen kann, da der zulässige Sulfatgehalt des ablaufenden Wassers erheblich überschritten wird.Force the protection of waters not significantly intensified in recent years, the provisions beverage operations, spent waste water as at present directly in d ', but to treat derive e Kan isation this before in ertsprechender way!. An obvious way of fulfilling the requirements mentioned at the beginning is the neutralization of the wastewater produced. However, due to the discharge requirements, this neutralization must be preceded by cooling to 35 ° C through intermediate storage or through heat exchange. The chemical reaction is defined to the effect that the H- * (or H3O + ) ions responsible for the acid reaction of a solution react with the OH - ions causing the basic reaction and combine to form neutral water as soon as the alkali is combined with acid . Treatment with sulfuric acid, hydrochloric acid, etc. would be conceivable for the neutralization of the used cleaning liquor from container treatment machines, although the use of sulfuric acid cannot be used for wastewater reasons, since the permissible sulfate content of the draining water is significantly exceeded.

In diesem Zusammenhang ist es bereits bekannt, Abwässer, die gelöste Alkalien enthalten, durch Begasen mit Kohlensäure abzustumpfen. Es ist auch bereits bekannt, Abwässer in einem Pumpensumpf oder einem Pumpenspeisebehälter zu sammeln, und von dort aus einem Strömungsrohr zuzugeben, in welchem die Zugabe von Neutralisationschemikalien erfolgt Mit diesem allgemeinen Verfahren ist jedoch die eigentliche Erfindungsauf;jabe nicht lösbar, welche darin besteht, einen sehr hohen Rcinigungsgrad des abzuleitenden Wassers von Gefäßreinigungsmaschinen in Verbindung mit einem erheblich geringeren Kostenaufwand für Beschaffung und Betrieb derartiger Anlagen sicherzustellen, wobei in der aus mehreren hintereinander geschalteten Reinigungsanteilungen unterschiedlicher Konzentration bestehender! Reinigungsmaschine eineIn this context, it is already known to fumigate wastewater containing dissolved alkalis to dull with carbonic acid. It is also already known, sewage in a pump sump or a To collect pump feed tanks, and from there to add a flow pipe in which the Addition of neutralization chemicals is done using this general procedure, however, is the real one Invention task, which is not solvable, consists in a very high degree of purification of the water to be discharged from vessel cleaning machines with a significantly lower cost for the procurement and operation of such systems to ensure, with several in a row switched cleaning proportions of different concentrations of existing! Cleaning machine one wirtschaftliche Neutralisation der verschleppten Laugenteile ermöglicht werden soll.economic neutralization of the entrained liquor parts should be made possible.

Das zur Lösung dieser Aufgabe vorgeschlagene Verfahren der eingangs genannten Art zeichnet sich erfindungsgemäß dadurch aus, daß die bei der Gegendruckfüllung von Gefäßen in der Füllmaschine nach Behandlungsabschluß anfallende überschüssige Kohlensäure einem Sammelgefäß zugeleitet und von diesem in ein oder mehreren Teilströmen einerseits einer Abwasserneutralisationsanlage zugegeben und andererseits einem im Zuge der Reinigungsanlage angeordneten Lauge-Neutralisatiunsbad zugeleitet wird.The method of the type mentioned at the outset that is proposed to solve this problem is distinguished according to the invention characterized in that the counterpressure filling of vessels in the filling machine After the end of the treatment, excess carbonic acid is fed to a collecting vessel and from this in one or more substreams on the one hand added to a wastewater neutralization system and on the other hand, a lye neutralization bath arranged in the course of the cleaning system will.

Dabei hat es sich als zweckmäßig erwiesen, daß die Entnahme des zu neutralisierenden Abwassers und die Zugabe der Kohlensäure sowohl zur Neutralisationsanlage, als auch zum Lauge-Neutralisationsbad kontinuierlich und im wesentlichen synchron zur Durchsatzleistung der Reinigungsmaschine erfolgt.It has proven to be useful that the The waste water to be neutralized is withdrawn and the carbon dioxide added to both the neutralization system and the lye neutralization bath is carried out continuously and essentially synchronously with the throughput of the cleaning machine.

Mit diesem Verfahren ist ein besonders wirtschaftlicher Betrieb von Gefäßbehandlungsanlagen möglich. Die in einer Gegendruckfüllmaschine anfallende überschüssige Kohlensäure wird auf einfache Weise zur Lösung des Problems ausgenutzt Mit der überschüssigen Kohlensäure wird einerseits die Neutralisation des anfallenden Abwassers einer Reinigungsmaschine und andererseits die Neutralisation des in der Maschine angeordneten Bades, dessen Neutralität durch kontinuierliche Verschleppung von Laugeresten gefährdet ist, sichergestelltWith this method, a particularly economical operation of vessel treatment systems is possible. The excess carbon dioxide produced in a counter pressure filling machine is easily converted into Solution to the problem exploited With the excess carbon dioxide, on the one hand, the neutralization of the accumulating wastewater of a cleaning machine and on the other hand the neutralization of the in the machine arranged bath, the neutrality of which is endangered by the continuous carryover of lye residues, ensured

Die zur Durchführung des erfindungsgemäßen Verfahrens beispielsweise geeignete Vorrichtung, bestehend aus einer Gefäßbehandlungsanlage mit einer Reinigungs- und Füllmaschine t nd einer der Reinigungsmaschine zugeordneten Abvasserneutralisationsanlage, zeichnet sich dadurch aus, daß eine mit dem Abgasventil einer Füllmaschine verbundene COrSammelleitung zu einem CO2 Sammelgefäß geführt ist, von welchem mindestens eine Leitung zu dem in der Reinigungsmaschine eingegliederten Laugenneutralisationsbad und eine weitere Verteilsrleitung zu der Abwasserneutralisationsanlage führt, welche mit einem Abwasser-Pufferbehälter und einer Mischstrecke ausgerüstet und zwischen welchem ein Injektor mit einem Anschluß an die CO2-Verteilerleitung eingegliedert ist.The device suitable for performing the method according to the invention, for example, consisting of a vessel treatment system with a Cleaning and filling machine t nd a waste water neutralization system assigned to the cleaning machine, is characterized in that one with the Exhaust valve of a filling machine connected COr collecting line to a CO2 collecting vessel is led from which at least one line to the lye neutralization bath incorporated in the cleaning machine and a further distribution line to the Waste water neutralization system leads, which is equipped with a waste water buffer tank and a mixing section and between which an injector with a Connection to the CO2 distribution line is incorporated.

Im nachfolgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsschemas näher beschrieben.In the following, the invention is based on an in the drawing illustrated execution scheme described in more detail.

Die Anlage zur Neutralisation des in Gefaßbehandlungsmaschinen anfallenden Abwassers besteht im wesentlichen aus einer Füllmaschine 1 zum Abfüllen von unter Gegendruck stehender Flüssigkeit in Gefäße und einer dieser vorgeschalteten Reinigungsmaschine 2, welche mit einer Abwasserneutralisationsanlage 3 in Verbindung steht. Von der Füllmaschine 1 führt über eine nicht dargestellte Verteileranlage eine COj-Sammelleitung 4 zu einem Sammelgefäß 5. Die aus mehreren hintereinandergeschaltetcn Reinigungsabteilungen bestehende Gefäßreinigungsmaschine weist ein Neutralisationsbad 6 auf. Gemäß dem dargestellten Ausfuhrungsbeispiel führt von dem SammefgefäU 5 eine Verteilerleitung 7 zum Neutraiisationsbad 6 und eine weitere Verteilerleitung H zur Abwasserncutralisationsanlage 3. Diese Anlage besteht beispielsweise aus einem Abwasser-Puffergefäß 9 und einer Mischstrcckc 10. Zwischen dem Puffergefäß 9 und der Mischstreckc IO ist ein Injector Il eingegliedert und mit der Verteilerleitung 8 verbunden.The plant for the neutralization of the wastewater accumulating in vessel treatment machines exists in the essentially from a filling machine 1 for filling liquid under counterpressure into vessels and one of these upstream cleaning machines 2, which with a wastewater neutralization system 3 in Connection. A COj collecting line 4 leads from the filling machine 1 to a collecting vessel 5 via a distributor system (not shown) Several cleaning departments connected in series have a vessel cleaning machine Neutralization bath 6 on. According to the exemplary embodiment shown, one leads from the collecting vessel 5 Distribution line 7 to Neutraiisationsbad 6 and one further distribution line H to Abwasserncutralisationsanlage 3. This system consists, for example, of one Waste water buffer vessel 9 and a mixing section 10. Between the buffer vessel 9 and the mixing section IO is an injector II incorporated and connected to the distribution line 8.

Die in der Füllmaschine nicht mehr verwertbare Kohlensäure wird durch die Leitung 4 dem COrSammelgefäß 5 zugeleitet und von hier aus in beliebig wählbaren Teilströmen dem Neutralisationsbad 6 und/oder dem Injector 11 entlang der Leitungsführung 8 zugeführt, und Ober diesen in das abfließende Abwasser gebracht Das gasförmige COj reagiert mit der Lauge, wodurch eine Absenkung des pH-Wertes in den zulässigen Bereich sichergestellt wird.The carbon dioxide, which can no longer be used in the filling machine, is fed through line 4 to the CO r collecting vessel 5 and from here fed in any selectable partial flows to the neutralization bath 6 and / or the injector 11 along the line routing 8, and via this into the draining wastewater The gaseous COj reacts with the lye, which ensures that the pH value is reduced to within the permissible range.

Die Zufuhr des COrGases wird in bekannter Weise beispielsweise über ein pH-Meßgerät in Verbindung mit Ventilen und dergleichen geregelt Zur Neutralisation der verwendeten Lauge NaOH müssen pro g 1,1 g CO2 zudosiert werden. Für 30 m3 Abfallauge von 1 % nach diesem Beispiel etwa 330 kg. Die zur Durchführung des erfindungsgemäßen Verfahrens vorgeschlagene Anlage weist beispielsweise eine Füllmaschine mit Vorevakuierung und COrVorspannung auf. Hierbei wird inThe supply of the COr gas is regulated in a known manner, for example via a pH measuring device in connection with valves and the like. To neutralize the NaOH caustic solution used, 1.1 g of CO 2 must be added per g. For 30 m 3 of waste eye of 1% according to this example about 330 kg. The system proposed for carrying out the method according to the invention has, for example, a filling machine with pre-evacuation and COr pre-tensioning. Here, in

regelmäßiger Folge ein COj-Zusatz von 120—150 g/hl erforderlich, Von dieser Zusatzmenge können bei dem genannten Vorevakuierungsföller etwa 100 g/hl am Abgasventil aufgefangen und der Neutralisationsanlage zugegeben werden. Wöchentlich ergeben sich dann bei der betrachteten Anlagengröße mit einem Wirkungsgrad von 85% etwa 1000 kg CO2, wovon nur ein Drittel zur Neutralisation des Abwassers bzw. der Lauge benötigt wird. Mit dem Überschuß kann die Laugenverschleppung im Bad 6 neutralisiert werden.Regularly a COj addition of 120-150 g / hl is required. About 100 g / hl of this additional amount can be collected at the exhaust valve at the pre-evacuation filler and added to the neutralization system. With an efficiency of 85%, this results in around 1000 kg of CO 2 per week, of which only a third is required for the neutralization of the wastewater or the lye. The carryover of lye in bath 6 can be neutralized with the excess.

Die COrSammelleitung 4 ist mit einer weiteren nicht näher dargestellten Rückleitung verbunden, weiche zu einer ebenfalls nicht dargestellten COrGewinnungsanlage führt Auf diesem Wege kann die zur Durchführung der Neutralisation nicht verwertbare überschüssige Kohlensäure im normalen Kreislauf nach der Zugabe zur COrGewinnungsanlage erneut verwendet werden.The COr collecting line 4 is connected to a further return line, not shown in detail, which is closed a COr recovery system, also not shown. In this way, the can be carried out Excess carbon dioxide that cannot be used for neutralization in the normal cycle after the addition can be reused for the COr recovery system.
