Description

Kreislaufverfahren zum umweit erträglichen Reinigen von schadstoffbehafteten Textilien, insbesondere Industrie- Putztüchern mit Lösungsmittel-Rückständen Circulation process for the widely tolerable cleaning of contaminated textiles, especially industrial cleaning cloths with solvent residues
Beschreibungdescription
Die Erfindung betrifft ein Kreislaufverfahren zum umweltverträglichen Reinigen von schadstoffbehafteten Textilien, insbesondere Industrie-Putztüchern mit Lösungsmittel-Rückständen, wobei das Reinigungsgut einer Industrie-Waschmaschine sowie nach dem Waschprozess einem Trockner zugeführt wird, gemäß Oberbegriff des Patentanspruchs 1, sowie eine Anordnung zur Durchführung eines derartigen Verfahrens .The invention relates to a cycle method for environmentally friendly cleaning of contaminated textiles, in particular industrial cleaning cloths with solvent residues, the items to be cleaned being fed to an industrial washing machine and after the washing process to a dryer, according to the preamble of claim 1, and an arrangement for carrying out such Procedure.
Industriewasch- und Reinigungsanlagen sind seit Jahrzehnten Stand der Technik. Im Zuge einer ökologischen Verfahrensführung gilt es bei derartigen Anlagen, sowohl Energie beim Beheizen der eigentlichen Wascheinrichtungen und Trockner einzusparen als auch den Brauchwasserbedarf zu senken.Industrial washing and cleaning systems have been state of the art for decades. In the course of an ecological process management, it is important in such systems to both save energy when heating the actual washing facilities and dryers and to reduce the consumption of process water.
Insbesondere bei Industrietextilien, z.B. Industrie-Putz- tüchern, besteht das Problem, dass derartige Textilien im Regelfall mit Lösungsmitteln und damit Schadstoffbehaftet sind. Derartige Lösungsmittel werden beim Wasch- und Trockenprozess freigesetzt und gelangen bisher als Schadstoffe in die Umwelt. Eine Kreislaufanordnung in Sachen zugeführtes Frischwasser und aufbereitetes Abwasser durch Kondensation wurde bereits vorgeschlagen, jedoch sind die energetischen Aufwendungen hierfür erheblich, so dass bei einer derartigen Verfahrensführung respektive entsprechend ausgestalteten Anlagen nicht von einem betriebswirtschaftlich sinnvollen Procedere ausgegangen werden kann.Especially with industrial textiles, e.g. Industrial cleaning cloths, there is the problem that such textiles are usually contaminated with solvents. Such solvents are released during the washing and drying process and have so far been released into the environment as pollutants. A circuit arrangement in terms of fresh water supplied and treated wastewater by condensation has already been proposed, but the energy expenditure for this is considerable, so that a procedure which is economically reasonable cannot be assumed with such a process management or correspondingly designed systems.
Aus dem Vorgenannten ist es daher Aufgabe der Erfindung, ein unter Umweltaspekten weiterentwickeltes Kreislaufverfahren sowie eine zugehörige Anordnung zum Reinigen von schadstoffbehafteten Textilien, insbesondere Industrie-Putztuchern mit Lösungsmittel-Rückständen anzugeben, wobei nicht nur die Frischwasserzufuhr minimiert werden soll, sondern gleichzeitig ein energetisch optimaler Betrieb der gesamten Einrichtung zu sichern ist .From the foregoing, it is therefore an object of the invention to provide a circuit process which has been further developed from an environmental point of view and an associated arrangement for cleaning textiles which are contaminated with pollutants, in particular industrial cleaning cloths with solvent residues, the aim being not only to minimize the fresh water supply but also at the same time an energetically optimal operation of the entire facility must be ensured.
Die Lösung der Aufgabe der Erfindung erfolgt mit einem Ver- fahren gemäß den Merkmalen nach Patentanspruch 1 sowie einer Anordnung zur Durchführung des Verfahrens mit den Merkmalen nach Patentanspruch 7, wobei die Unteransprüche mindestens zweckmäßige Ausgestaltungen und Weiterbildungen umfassen.The object of the invention is achieved with a method according to the features according to patent claim 1 and an arrangement for carrying out the method with the features according to patent claim 7, the subclaims comprising at least expedient refinements and developments.
Demnach liegt der Grundgedanke der Erfindung darin, die beim Wasch- und Trockenprozess freigesetzten lösungsmittelhaltigen und damit energieseitig interessanten Dämpfe und Gase aufzufangen, um in einer thermischen Oxidationskammer nicht nur ein Umwandeln der Schadstoffe zu erreichen, sondern zugleich die energetische Bilanz der Kammer bzw. des Kammerbetriebs zu verbessern.Accordingly, the basic idea of the invention is to collect the solvent-containing vapors and gases that are released in the washing and drying process and are therefore interesting in terms of energy, in order not only to convert the pollutants in a thermal oxidation chamber, but also to achieve the energy balance of the chamber or the chamber operation to improve.
Im Sinne dieses Grundgedankens wird die Abluft aus Waschmaschine und/oder Trockner aufgefangen und über eine Sammel- einrichtung mit Frischluft vermengt und gegebenenfalls vorge- wärmt oder gekühlt der thermischen Oxidationskammer zugeführt . Weiterhin besteht die Möglichkeit, flüssige Lösungsmittel- Rückstände durch eine Düsenanordnung der Kammer zuzuleiten.In line with this basic idea, the exhaust air from the washing machine and / or dryer is collected and mixed with fresh air via a collecting device and, if necessary, is preheated or cooled and fed to the thermal oxidation chamber. It is also possible to feed liquid solvent residues through a nozzle arrangement to the chamber.
Es hat sich überraschenderweise gezeigt, dass durch eine solche zusätzlich Energiezufuhr bedingt durch die Lösungsmittel-Rückstände in gasförmiger und/oder flüssiger Form eine erhebliche Einsparung von Gas oder sonstigen Brennmaterialien die Folge ist.Surprisingly, it has been shown that such additional energy supply, due to the solvent residues in gaseous and / or liquid form, results in a considerable saving in gas or other fuel.
Die in der Kammer beim Abluftreinigungsprozeß erzeugte Energie wird dann weiterhin erfindungsgemäß einem Dampferzeuger zugeführt, dessen Heißdampf auf eine Schmutzwasser-Reinigungsund Verdampf ngsanlage gelangt ist .The energy generated in the chamber during the exhaust air cleaning process is then further supplied according to the invention to a steam generator, the superheated steam of which has reached a dirty water cleaning and evaporation system.
Die Schmutzwasser-Reinigungsanlage ist bevorzugt mehrstufig ausgeführt und umfasst Einrichtungen zum Separieren bzw. Abscheiden von nicht kondensierfähigen Rückständen. Es gelingt demnach, nicht nur einen Wasch-Schmutzwasser-Kreis- lauf durch eine Verdampfungs- bzw. Kondensierungsanlage zu schaffen, sondern die energetische Versorgung der Verdampfungsanlage für das Schmutzwasser durch Nutzung der Energie der lösungsmittelhaltigen Rückstände, die in den verschmutzten Textilien gebunden sind, zu optimieren.The dirty water cleaning system is preferably designed in several stages and comprises devices for separating or separating non-condensable residues. Accordingly, it is not only possible to create a washing / dirty water circuit through an evaporation or condensation system, but also to provide the evaporation system with energy for the dirty water by using the energy of the solvent-containing residues that are bound in the soiled textiles optimize.
Wie bereits angedeutet, gilt es also zunächst, die gesammelten Abluftströme aus der Industrie-Waschmaschine und/oder dem Trockner in eine Kammer zu leiten, um diese dort zu oxidieren bzw. thermische Energie freizusetzen.As already indicated, the first thing to do is to guide the collected exhaust air streams from the industrial washing machine and / or the dryer into a chamber in order to oxidize them there or release thermal energy.
Die thermische Energie aus der Abluft wird dann auf einen Dampferzeuger geführt, der mit einer Einrichtung zum Vorwärmen des Waschwassers und einer Schmutzwasser-Verdampfungsanlage in Verbindung steht, so dass die angestrebte minimale Fremdenergie-Zufuhr sowohl beim Verdampfen und damit Reinigen des Schmutzwassers als auch beim Aufheizen des derart gereinigten, der Industrie-Waschmaschine wieder zuführbaren Brauchwassers erreichbar ist .The thermal energy from the exhaust air is then passed to a steam generator, which is connected to a device for preheating the wash water and a dirty water evaporation system, so that the desired minimum external energy supply when evaporating and thus cleaning the dirty water as well as during heating of the purified industrial water washing water that can be supplied again.
Aus den Abluftströmen kondensierte, stark lösungsmittelhaltige Rückstände bzw. derartige im Trockner aufgefangene Rückstände können über eine Düsenanordnung in die Kammer aufgegeben werden, so dass eine weitere Verbesserung des Wirkungsgrads im gesamten Kreislaufverfahren gegeben ist. Gleiches gilt für aus dem Waschwasser destillierte brennbare Stoffe.Highly solvent-containing residues condensed from the exhaust air streams or residues of this type collected in the dryer can be introduced into the chamber via a nozzle arrangement, so that there is a further improvement in the efficiency in the entire cycle process. The same applies to flammable substances distilled from the wash water.
Die in der Schmutzwasser-Reinigungsanlage aufgefangenen festen oder sonstigen Rückstände können einem separaten Recycling zugeführt werden. In dem Fall, wenn solche Rückstände brennbar sind, besteht zusätzlich die Möglichkeit einer entsprechenden Aufgabe bezogen auf die Kammer.The solid or other residues collected in the wastewater treatment plant can be recycled separately. In the event that such residues are combustible, there is also the possibility of a corresponding task related to the chamber.
Die Abluftströme werden über eine entsprechende Regeleinrichtung mit einem Frischluftstrom vermengt und gegebenenfalls über eine Vorwärmeinrichtung der Kammer zugeleitet, wobei die Vorwärmeinrichtung sich im Abgasstrom der Kammer, d.h. im Reingasweg befindet .The exhaust air streams are mixed with a fresh air stream via a corresponding control device and, if necessary, fed to the chamber via a preheating device, the Preheater is in the exhaust stream of the chamber, ie in the clean gas path.
Die Schmutzwasser-Reinigungsanlage enthält Filtereinrichtungen, mindestens einen Vorverdampfer, einen Zentrifugal-Abscheider sowie eine nachgeschaltete Stufe mit Zwangsumlauf-Verdampfer, so dass der Verdampfungsprozess wesentlich wirtschaftlicher bezogen auf den Stand der Technik und mit minimalem Wasseranteil im Abfallwerkstoff gestaltbar ist.The dirty water cleaning system contains filter devices, at least one pre-evaporator, a centrifugal separator and a downstream stage with a forced circulation evaporator, so that the evaporation process can be designed much more economically based on the state of the art and with a minimal water content in the waste material.
Bei der Anordnung zur Durchführung des Verfahrens wird zunächst von einer Waschmaschinen- und/oder Trocknerabluft-Sammelleitung ausgegangen, welche über eine entsprechende Ventilationseinrichtung auf einen Abluftvorwärmer gelangt und dann mit einer vorzugsweise gasbeheizten Oxidationskammer in Verbindung steht . Eine Mischeinrichtung dient der geregelten Zuführung von Frischluft zur Kammer bzw. zur Einstellung des Verhältnisses zwischen Frischluft und Waschmaschinen- bzw. Trocknerabluft.In the arrangement for carrying out the method, a washing machine and / or dryer exhaust air collecting line is initially assumed, which line reaches an exhaust air preheater via a corresponding ventilation device and is then connected to a preferably gas-heated oxidation chamber. A mixing device is used for the regulated supply of fresh air to the chamber or for setting the ratio between fresh air and washing machine or dryer exhaust air.
Bei einer Weiterbildung der Anordnung wird die hochbelasteteIn a further development of the arrangement, the highly stressed
Abluft der Waschstraße über eine gesicherte Rohrleitung in der Oxidationskammer thermisch behandelt. Die leichter belastete abgesaugte Raumluft und die Trocknerabluft wird ebenfalls der Oxidationskammer zugeführt, jedoch wird dieser Teilstrom reguliert, um eine Überhitzung der Kammer wirksam zu verhindern.Exhaust air from the car wash is thermally treated via a secured pipe in the oxidation chamber. The less polluted extracted room air and the dryer exhaust air are also fed to the oxidation chamber, but this partial flow is regulated to effectively prevent the chamber from overheating.
Der Kammer direkt nachgeschaltet ist ein Dampferzeuger, der die Gase abkühlt und entsprechenden Heißdampf bereitstellt. Der Abluftvorwärmer dient der weiteren Abkühlung der Reingase unter gleichzeitiger Erwärmung der Abluft. Wenn bei fehlender Wärmeabnahme durch den Dampferzeuger höhere Temperaturen im nachgeschalteten Abluftvorwärmer auftreten und die Gefahr von Vorzündungen abluftseitig besteht, kann der Abluftvorwärmer reingasseitig umfahren werden.Downstream of the chamber is a steam generator, which cools the gases and provides the corresponding superheated steam. The exhaust air preheater is used for further cooling of the clean gases while heating the exhaust air. If, when there is no heat consumption by the steam generator, higher temperatures occur in the downstream exhaust air preheater and there is a risk of pre-ignition on the exhaust air side, the exhaust air preheater can be bypassed on the clean gas side.
Die Kammer selbst besitzt eine zusätzliche Düsenanordnung zum Verdüsen von lösungsmittelhaltigen Flüssigkeits-Rückständen, so dass die in diesen Rückständen enthaltene Energie im Verbren- nungsprozess nutzbar ist .The chamber itself has an additional nozzle arrangement for spraying solvent-containing liquid residues, so that the energy contained in these residues can be used in the combustion process.
Mit der vorgestellten Erfindung gelingt es also, während des Wasch- und Reinigungsprozesses von Industrietextilien dieWith the presented invention, it is possible to achieve this during the washing and cleaning process of industrial textiles
Abluft aus der Waschmaschine und Umgebung der Waschmaschine aufzufangen und über ein Rohrsystem einer thermischen Oxida- tionskammmer zuzuführen. Hierdurch entfällt eine Belastung der Atmosphäre . Im gleichen Sinn kann auch die Abluft der Trockner aufgefangen und der Kammer zugeführt werden.Collect exhaust air from the washing machine and the area around the washing machine and feed it to a thermal oxidation chamber via a pipe system. This means there is no pollution of the atmosphere. In the same sense, the exhaust air from the dryer can be collected and fed to the chamber.
Die mit erheblichen brennbaren Stoffen belastete Abluft setzt bei ihrer Verbrennung Energie frei, die zur Beheizung des Dampferzeugers verwendet wird. Die freigesetzte Energie wiederum dient zum Aufheizen des Waschwassers und zur energe- tischen Versorgung der Verdampfungsanlage für das Schmutzwasser. Durch eine Schmutzwasser-Reinigungsanlage mit nachgeschaltetem Zwangsumlauf-Verdampfer kann das gesamte Waschwasser wieder verwendet werden. Eine Belastung öffentlicher Kläranlagen mit kontaminierten Materialien erfolgt nicht .The exhaust air, which is contaminated with considerable combustible substances, releases energy when it is burned, which is used to heat the steam generator. The released energy in turn serves to heat the washing water and to supply the evaporation system with energy for the dirty water. The entire wash water can be reused by means of a dirty water cleaning system with a downstream forced circulation evaporator. There is no contamination of public sewage treatment plants with contaminated materials.

Wie in Fig. 1 gezeigt, wird das Waschgut 1, enthalten in sogenannten Putztuchbehältern, einer Industrie-Waschmaschine 2 aufgegeben. Nach dem Waschprozess werden die Textilien in einen Trockner 3 überführt. Nach dem Trockenprozess erfolgt ein Verpacken und Versandfertigmachen an einer entsprechenden Station 4. Die an der Waschmaschine 2 bzw. dem Trockner 3 oder in der Umgebung dieser aufgefangene Abluft 5 wird einer Abluftbehandlung in einer Oxidationskammer 6 zugeführt. Die freige- setzte Energie gelangt auf einen Dampferzeuger 7. Der erzeugte Heißdampf 8 dient dann der energetischen Versorgung einer Schmutzwasser-Reinigungsanlage 9.As shown in FIG. 1, the laundry 1, contained in so-called cleaning cloth containers, is placed in an industrial washing machine 2. After the washing process, the textiles are transferred to a dryer 3. After the drying process, packaging and ready for shipment take place at a corresponding station 4. The exhaust air 5 collected on the washing machine 2 or the dryer 3 or in the vicinity of the latter is fed to an exhaust air treatment in an oxidation chamber 6. The released energy reaches a steam generator 7. The superheated steam 8 is then used for the energy supply of a dirty water cleaning system 9.
Das Schmutzwasser 10 wird der Schmutzwasser-Reinigungsanlage 9 aufgegeben und dort bevorzugt mehrstufig behandelt und gereinigt und steht ausgangsseitig der Schmutzwasser-Reinigungsanlage als Brauch- oder Waschwasser 11 wieder zur Verfügung. Auf diese Weise gelingt eine Reduzierung des Frischwasserverbrauchs .The dirty water 10 is given to the dirty water cleaning system 9 and is preferably treated and cleaned there in several stages and is again available on the output side of the dirty water cleaning system as service or wash water 11. In this way, fresh water consumption is reduced.
Mit Hilfe der Fig. 2 sei nun ein Ausführungsbeispiel zum Betreiben der Oxidationskammer 6 gemäß der Erfindung erläutert ,An exemplary embodiment for operating the oxidation chamber 6 according to the invention will now be explained with the aid of FIG. 2,
Die Kammer 6 besitzt eine geregelte BrenngasZuführung 12 sowie eine Anordnung zum Verdüsen 13 von flüssigen Lösungsmittel- Rückständen.The chamber 6 has a controlled fuel gas supply 12 and an arrangement for atomizing 13 liquid solvent residues.
Der Kammer-Abgasstrom wird dem Dampferzeuger 7 zugeführt . Ausgangsseitig des Dampferzeugers gelangt der Abgasstrom auf einen Abluftvorwärmer 14.The chamber exhaust gas stream is fed to the steam generator 7. On the output side of the steam generator, the exhaust gas stream reaches an exhaust air preheater 14.
Frischluft 15 wird mit Abluft 5 über Regeleinrichtungen vermischt und entweder unmittelbar der Kammer 6 oder mittels des Abluftvorwärmers 14 vorgewärmt der Kammer 6 zugeführt .Fresh air 15 is mixed with exhaust air 5 via control devices and supplied either directly to the chamber 6 or preheated to the chamber 6 by means of the exhaust air preheater 14.
Die beim gezeigten Beispiel mit einem Gasbrenner ausgerüstete Kammer 6 ist in der Lage, bei ca. 720°C in der Abluft vorhandene Schadstoffe sicher unter Reinluft-Grenzwerte zu oxidieren.The chamber 6 equipped with a gas burner in the example shown is capable of safely oxidizing pollutants present in the exhaust air at about 720 ° C. below clean air limit values.
Der der Kammer 6 nachgeschaltete Dampferzeuger 7 kühlt die Reingase von ca. 720 °C auf 250 °C ab und setzt dabei eine Energieleistung von z.B. 900 kW bei einer Produktionsleistung der Waschanlage von 500 bis 600 kg/h Maschinenputztüchern frei. Dies entspricht einer Leistung von im wesentlichen 1300 kg/h Sattdampf mit einem Druck von 14 bar.The steam generator 7 connected downstream of the chamber 6 cools the clean gases from approx. 720 ° C. to 250 ° C. and releases an energy output of, for example, 900 kW with a washing machine production output of 500 to 600 kg / h machine cleaning cloths. This corresponds to an output of essentially 1300 kg / h of saturated steam at a pressure of 14 bar.
Der Abluftvorwärmer 14, der dem Dampferzeuger 7 nachgeschaltet ist, kühlt die Reingase weiter auf ca. 150 °C ab und dient der Erwärmung der Abluft von ca. 35°C auf ca. 135°C.The exhaust air preheater 14, which is connected downstream of the steam generator 7, further cools the clean gases to approximately 150 ° C. and serves to heat the exhaust air from approximately 35 ° C. to approximately 135 ° C.
Bei voller Abnahme der Dampfmenge während des Anlagebetriebs wird ein Ansteigen der Reingastemperatur nach dem Dampfkessel ausgeschlossen. Bei reduzierter oder fehlender Wärmeabgabe wird zur Vermeidung höherer Temperaturen im nachfolgenden Abluft- Vorwärmer und zum Verhindern von Vorzündungen der Abluftvor- wärmer reingasseitig umfahren.If the amount of steam is fully reduced during system operation, an increase in the clean gas temperature after the steam boiler is excluded. In the event of reduced or no heat output, the exhaust air preheater is bypassed on the clean gas side to avoid higher temperatures in the downstream exhaust air preheater and to prevent pre-ignition.
Bei der vorbeschriebenen Anordnung ist mit folgenden Gasverbräuchen zu rechnen:With the arrangement described above, the following gas consumption can be expected:
0 g Lösungsmittel/m3 mit 5000 Nm3/h ca. 120 Nm3/h mit Hu (Gas) = 10 kWh/Nm3 0 g solvent / m 3 with 5000 Nm 3 / h approx. 120 Nm 3 / h with Hu (gas) = 10 kWh / Nm 3
8 g Lösungsmittel/m3 mit 5000 Nm3/h ca. 80 Nm3/h mit Hu (Gas) = 10 kWh/Nm3 8 g solvent / m 3 with 5000 Nm 3 / h approx. 80 Nm 3 / h with Hu (gas) = 10 kWh / Nm 3
Um weiteren Brennstoff einzusparen, sei auf die bereits erläu- terte Möglichkeit des Eindüsens von Flüssigkeits-Rückständen in die Kammer verwiesen.In order to save further fuel, reference is made to the possibility already explained of injecting liquid residues into the chamber.
Hierbei ist von folgenden Gasverbräuchen auszugehen:The following gas consumption can be assumed here:
30 kg/h FR in 5000 Nm3/h mit 8 g/m3 ca. 50 Nm3/h mit Hu (Gas) = 10 kWh/Nm3 30 kg / h FR in 5000 Nm 3 / h with 8 g / m 3 approx. 50 Nm 3 / h with Hu (gas) = 10 kWh / Nm 3
