Ein.naheliegendes Verfahren zur Erfüllung der eingangs genannten Auflagen stellt die Neutralisation des anfallenden Abwassers dar. Dieser Neutralistation muß allerdings aufgrund der Einleitungsanforderungen eine Abkuhlung auf 3500 durch Zwischenlagerung oder durch Wärmeaustausch vorausgehen. Die chemische Reaktion ist dahingehend definiert, daß die für die Sdurereaktion einer Lösung verantwortlichen H+ (bzw. H3O+)-Ionen mit den die basische Reaktion verursachenden OH#-Ionen reagieren und sich zu neutralem Wasser zusammenlagern, sobald Lauge mit Sdure zusammengebracht wird. Für die Neutralitation der verbrauchten Reinigungslauge von GofUßbehandlungsmoschinen wore die Anwendung von Schwefelsäure, Salzsäure und Kohlensäure denkbar, wobei die Verwendung von Sc'hwefelsdure aus ab#iassertechnischen GrUnden nicht zum Ansatz kommen kann, da der zulässige Sulfatgehalt des ablaufenden Wassers erheblich übersChritten wird.An obvious procedure to meet the requirements mentioned at the beginning represents the neutralization of the waste water produced. This neutralization station However, it has to cool down to 3500 due to the introduction requirements Intermediate storage or heat exchange precede. The chemical reaction is defined to the effect that those responsible for the acid reaction of a solution H + (or H3O +) ions react with the OH # ions causing the basic reaction and combine to form neutral water as soon as the lye is combined with the acidic acid will. For the neutralization of the used cleaning solution from GofUß treatment machines wore the use of sulfuric acid, hydrochloric acid and carbonic acid conceivable, whereby the Use of sulfuric acid for ab # iassertechnical reasons not to approach can occur, since the permissible sulfate content of the runoff water has increased considerably will.

Dabei hat es sich bei einer mit aus mehreren Reinigungsabteilungen bestehenden Reinigungsmuschine als zweckmäßig erwiesen, daß wenigstens eine der Reinigungsobteilungen als Neutralisationsbad ausgebildet und mit der CO2-Sammelleitung verbunden ist.It was one of several cleaning departments Existing cleaning machine proved to be useful that at least one of the Cleaning compartments designed as a neutralization bath and with the CO2 collecting line connected is.
Schließlich wird nach einer selbständigen Variante der Erfindung vorgeschlagen, daß die CO2-Sammelleitung zu einem CO2'Sammelgeföß geführt ist, von welchem mindestens eine Leitung zu dem in der Reinigungsmaschine eingegliederten Laugenneutralisationsbad und eine weitere Verteilerleitung zu der Abwasserneutrolisotionsanlage fUhrt, welche mit einem Abwasser-Pufferbehalter und einer Mischstrecke ausgerüstet und zwischen welchen ein Injector mit einem Anschluß an die C02-Verteilerleitung eingegliedert ist.Finally, according to an independent variant of the invention, it is proposed that that the CO2 collecting line is led to a CO2 collecting vessel, of which at least a line to the alkaline neutralization bath integrated in the cleaning machine and another distribution line leads to the sewage neutralization plant, which equipped with a waste water buffer tank and a mixing section and between which integrated an injector with a connection to the C02 distribution line is.
Weitere Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines in der Zeichnung dargestellten Ausführungsschemas einer nach dem erfindungsgemäßen Verfahren arbeitenden Vorrichtung. Die Anlage zur Neutralisation des in Gefaßbehandlungsmaschinen anfallenden Abwassers besteht im wesentlichen aus einer Fulimaschine 1 zum Abfüllen von unter Gegendruck stehender Flüssigkeit in Gefäße und einer dieser vorgeschal teten Reinigungsmas hine 2, # ajlche mit einer Abwasserneutralisationsanlage 3 in Verbindung steht. Von der Füllmoschine 1 führt Überwei-ne nicht dargestellte Verteileranlage eine C02-Sammelleitung 4 zu einem Sammelgeftlß 5. Die aus mehreren hintereinandergeschalteten Reinigungsabteilungen bestehende Gefäßreinigungsmaschine weist ein Neutralisationsbad 6 auf.Further details of the invention emerge from the following Description of an implementation scheme shown in the drawing according to the device operating according to the method of the invention. The attachment to the Neutralization of the wastewater occurring in vessel treatment machines exists in essentially from a full machine 1 for filling under counter pressure Put liquid into vessels and one of these upstream cleaning agents 2, # ajlche is connected to a wastewater neutralization system 3. From the filling machine 1 leads over a distribution system, not shown, to a C02 collecting line 4 a collecting vessel 5. The one from several cleaning departments connected in series The existing vessel cleaning machine has a neutralization bath 6.
Gemaß dem dargestellten Ausführungsbeispiel führt von dem Sammelgefäß 5 eine Verteilerleitung 7 zum Neutralisationsbad 6 und eine weitere Verteiler~ leitung 8 zur Abwasserneutralisationsanlage 3. Diese Anlage besteht beispielsweise aus einet Abwasser-Puffergefaß 9 und einer Mischstrecke 10.According to the illustrated embodiment leads from the collecting vessel 5 a distribution line 7 to the neutralization bath 6 and a further distribution line 8 to the wastewater neutralization system 3. This system consists, for example, of a unit Waste water buffer vessel 9 and a mixing section 10.

Zur Neutralisation der verwendeten Lauge NaOH müssen pro g l,lg C02 zudosiert werden. Für 30m3 Abfallauge von 1% nach diesem Beispiel etwa 330 kg. Die zur Durchführung des erfindungsgemdßen Verfahrens vorgeschlagene Anlage weist beispielsweise eine Füllmaschine mit Vorevakuierung und C02-Vorspannung auf. Hierbei wird in regelmößiger Folge ein CO2-Zusatz von 120 -150 g/hl erforderlich. Von dieser Zusatzmenge können bei dem genannten Varevakuierungsfüller etwa 100 g/hl am Abgosventil aufgefangen und der Neutralisationsanlage zugegeben werden. Wöchentlich ergeben sich dann bei der betrachteten Anlugengröße mit einem Wirkungsgrad von 85 % etwa 1.000 kg ~cd2, wovon nur ein Drittel zur Neutralisation des Abwassers bzw. der Lauge benötigt wird. Mit dem Uberschuß kann die Laugenverschleppung im Bad 6 neutralisiert werden.The supply of the CO 2 gas is carried out in a known manner, for example via a pH meter in conjunction with valves and the like. For neutralization the NaOH lye used must be metered in per g l, lg C02. For 30m3 waste eye of 1% according to this example about 330 kg. The methods for carrying out the inventive The system proposed by the method has, for example, a filling machine with pre-evacuation and C02 bias. In this case, a CO2 addition of 120 -150 g / hl required. This additional amount can be used with the mentioned varevacuation filler about 100 g / hl collected at the exhaust valve and the Neutralization system be admitted. Weekly results then with the considered size of the eye with an efficiency of 85% about 1,000 kg ~ cd2, of which only a third is for neutralization of the wastewater or the lye is required. With the excess, the lye can be carried over can be neutralized in bath 6.
Die C02-Sammelleitung 4 ist mit einer weiteren nicht näher dargestellten RUckleitung verbunden, welche zu einer ebenfalls nicht dargestellten C02-Gewinnungsanlage fUhrt. Auf diesem Wege kann die zur Durchführung der Neutralisation nicht verwertbare Uberschussige Kohlensäure im normalen Kreislauf nach der Zugabef zur C02-Gewinnungsanlage erneut verwendet werden.The C02 collecting line 4 is not shown in detail with another Return line connected, which leads to a C02 recovery plant, also not shown leads. In this way, the can not be used to carry out the neutralization Excess carbon dioxide in the normal cycle after the addition to the C02 recovery system can be used again.
