Abstract
Description
Die Erfindung betrifft ein Verfahren zur Innenreinigung und/oder Trocknung von Tanks die mitunter Chemikalienreste enthalten.The invention relates to a process for the internal cleaning and / or drying of tanks which sometimes contain residues of chemicals.
Unter Tanks werden im Sinne der Erfindung Containern und sonstigen Behältnissen zur Lagerung, Bevorratung und Transport von Chemikalien verstanden.
Da in einem Tank bzw. Tankwagen nicht immer dieselben Produkte gelagert/transportiert werden, müssen diese zum Beispiel für einen Produktwechsel oder auch zur Sicherheitsüberprüfung gereinigt werden.
Aus der Chemikaliendatenbank ist für jedes Produkt eine Vorschrift zum Reinigen zu entnehmen. Ziel dieser Reinigungsrichtlinien ist es, zu einem eine Reinigung überhaupt erst zu ermöglichen und zu anderen die Reinigung unter ökologischen Gesichtspunkten optimal zu gestalten, so dass die Umwelt geringst möglich oder überhaupt nicht belastet wird. Zudem spielen bei der Tankreinigung auch ökonomische Gesichtspunkte eine Rolle, genauso wie der Arbeitsschutz besonders bei giftigen, krebserregenden und krebserzeugenden Produkten.For the purposes of the invention, tanks are understood to be containers and other containers for the storage, stockpiling and transport of chemicals.
Since the same products are not always stored / transported in a tank or tanker, they must be cleaned, for example, for a product change or for safety checks.
From the database of chemicals a regulation for cleaning of each product can be found. The aim of these cleaning guidelines is to make cleaning possible in the first place and to optimize the cleaning of the environment from an ecological point of view so that the environment is minimally possible or not at all contaminated. In addition, economic aspects play a role in tank cleaning, as well as occupational safety, especially for toxic, carcinogenic and carcinogenic products.
Bei den meisten Verfahren wird der Tank nach dem Restlosen entleeren mit einer Wassersprühvorrichtung, die auf die Domdeckelöffnung aufgesetzt wird, so lange gespült bis mit Hilfe des dreidimensional rotierenden Sprühkopfes alle Produktreste ausgespült sind.In most processes, the tank is emptied after complete emptying with a water spray device, which is placed on the dome lid opening, rinsed until flushed with the help of the three-dimensional rotating spray head all product residues.
Da für die Spülvorrichtung der Domdeckel eines Tanklaster geöffnet werden muss, ist es unmöglich ein austreten von Produktgasen zu verhindern. Um den zum Teil sehr starken Geruch zu reduzieren wird der Domdeckel deshalb erst einen Spalt weit geöffnet und durch diesen Spalt wird Aceton in den Tank geschüttet.Since the dome lid of a tank truck must be opened for the flushing device, it is impossible to prevent leakage of product gases. To reduce the sometimes very strong smell of the dome lid is therefore only a crack open wide and through this gap acetone is poured into the tank.
Ein weiterer Nachteil beim Stand der Technik ist, dass durch die Wasserspülung große Mengen des Wasserrestproduktgemisches anfallen die teuer entsorgt werden müssen. Die zu entsorgenden Menge kann bis zu mehrere 100l betragen.
Abschließend kann man sagen, dass mit den heute bekannten Verfahren zur Reinigung von Tanks immer geringe Mengen eines Produktes unkontrolliert in die Umwelt gelangen. So dass gerade Tankreinigungsunternehmen in der Nähe von Büros und/oder Wohnungen Tanks in denen geruchsintensive oder giftige Produkte enthalten sind nicht reinigen können.Another disadvantage of the prior art is that the water rinse large amounts of the residual water product mixture incurred which must be disposed of expensive. The amount to be disposed can be up to several 100l.
Finally, it can be said that with the methods known today for cleaning tanks always small quantities of a product reach the environment uncontrolled. So just tank cleaning companies near offices and / or homes can not clean tanks that contain odorous or toxic products.
Aufgabe der Erfindung ist es ein Verfahren und einen Vorrichtung zur Verfügung zu stellen, das bzw. die es erlaubt ein Innenreinigung und/oder Trocknung eines Tanks durchzuführen ohne das schädliche oder geruchsintensive Stoffe in die Umwelt gelangen.The object of the invention is to provide a method and a device which makes it possible to carry out an internal cleaning and / or drying of a tank without the harmful or odorous substances entering the environment.
Die Aufgabe wird mittels des Verfahrens mit den Merkmalen des Anspruchs 1 bzw. mittels einer Reinigungsvorrichtung mit den Merkmalen des Anspruches 9 gelöst.The object is achieved by means of the method with the features of claim 1 or by means of a cleaning device with the features of
Erfindungsgemäß wird ein Verfahren zur Innenreinigung und/oder Trocknung von Tanks, insbesondere Chemikalientanks vorgeschlagen, mit dem Tanks, die mind. einer Einlassvorrichtung und mind. einer Ablassvorrichtung zum befüllen bzw. entleeren des Tankes aufweisen, mittels folgender Schritte gereinigt und/oder getrocknet werden können. Dazu wird die Ablassvorrichtung des Tanks mit einer Auffangvorrichtung und diese wiederum mit einer Absaugfilteranlage verbunden.According to the invention, a method is proposed for internal cleaning and / or drying of tanks, in particular chemical tanks, with which tanks which have at least one inlet device and at least one outlet device for filling or emptying the tank can be cleaned and / or dried by means of the following steps , For this purpose, the discharge device of the tank is connected to a collecting device and this in turn connected to a Absaugfilteranlage.
Die Reinigung des Tanks erfolgt mittels Wasserdampf, der über die Einlassvorrichtung oder Befüllvorrichtung in den Tank eingeleitet wird. Durch die Absaugung wird das Dampf- und/oder Wasser-Chemikaliengemisch vom Tank in die Auffangvorrichtung gesaugt. Dort kondensiert es größtenteils zu einem Wasser-Chemikaliengemische. Nicht kondensierte Dämpfe/Gase werden in der Absaugfilteranlage mittels z.B. eines Aktivkohlefilters gefiltert, so dass keine Gase in die Umwelt gelangen. Nach der Reinigung wird die Dampfzufuhr unterbrochen und durch öffnen eines Frischluftventils oder des Domdeckels kann der Tank, mit Unterstützung des Luftzuges der Absaugfilteranlage von innen trocknen. Dadurch dass die Wandung des Tankes durch die hohen Temperaturen und die Einwirkzeit des Dampfes relativ warm werden, ist eine sehr schnelle Trocknung zu erreichen.The cleaning of the tank by means of steam, which is introduced via the inlet device or filling device in the tank. Through the suction, the steam and / or water-chemical mixture is sucked from the tank into the collecting device. There it mostly condenses to a water-chemical mixture. Uncondensed vapors / gases are filtered in the suction filter system by means of eg an activated carbon filter, so that no gases in get the environment. After cleaning, the steam supply is interrupted and by opening a fresh air valve or the dome lid, the tank, with the help of the air draft of the suction filter system, can dry from the inside. The fact that the wall of the tank by the high temperatures and the exposure time of the steam are relatively warm, a very fast drying can be achieved.
Die eigentliche Reinigung kann erst beginnen, wenn keine Chemikalienrestflüssigkeitsreste mehr im Tank sind. Die Reste werden deshalb vor der Wasserdampfeinleitung über die Ablassvorrichtung in die Auffangvorrichtung und /oder einen Transportbehälter geleitet.The actual cleaning can only begin when no residues of residual chemicals are left in the tank. The residues are therefore passed before the introduction of steam via the discharge device in the collecting device and / or a transport container.
Da der Filter z.B. ein Aktivkohlefilter keine hohen Temperaturen verträgt, werden die noch heißen nicht kondensierten Dämpfe/Gase zwischen der Auffangvorrichtung und der Absaugfilteranlage in einer Kühlvorrichtung z.B. mittels eines Kaltluftinjektors gekühlt. Durch die Kühlung wird zudem eine weitere Kondensation erreicht, so dass nur sehr geringe Mengen an Produktgasen zum Filter gelangen.Since the filter is e.g. an activated carbon filter does not tolerate high temperatures, the still hot uncondensed vapors / gases between the collecting device and the Absaugfilteranlage in a cooling device, e.g. cooled by means of a cold air injector. The cooling also achieves a further condensation, so that only very small amounts of product gases reach the filter.
Das aufgefangene Wasser - Chemikaliengemische wird nach Abschluss der Reinigung von der Auffangvorrichtung in einen Transportbehälter umgefüllt.The collected water - chemicals mixture is transferred to the completion of the cleaning of the catcher in a transport container.
Um die Einwirkzeit des Wasserdampfes zu verlängern und/oder die Temperatur und den Druck im Tank zu erhöhen, kann der Tank zeitweise von der Absaugfilteranlage und/oder der Auffangvorrichtung getrennt werden. Dies ist besonders dann sinnvoll wenn es sich um Auskristallisierte Produkte, wie Phenole handelt, die an der Innenwand des Tankes haften.In order to extend the exposure time of the water vapor and / or to increase the temperature and the pressure in the tank, the tank can be temporarily separated from the suction filter system and / or the collecting device. This is particularly useful when it comes to crystallized products, such as phenols, which adhere to the inner wall of the tank.
Eine weitere Möglichkeit die Reinigungswirkung für bestimmte Produkte zu erhöhen ist die Zugabe von Lösungsmitteln oder anderer Produkte in den Wasserdampf oder direkt in den Tank.Another way to increase the cleaning efficiency of certain products is to add solvents or other products to the water vapor or directly into the tank.
Vor der Wasserdampfreinigung kann der Tank zusätzlich mit Wasser oder Lösungsmittel aus einer Sprühvorrichtung gespült werden. Dazu wird eine Sprühlanze, mit nach oben gerichteten Düsen, durch ein Ventil im oberen Tankbereich in den Tank eingeführt. Damit möglichst keine Gase austreten, ist es besonders vorteilhaft wenn der Tank dabei bereits an der Auffangvorrichtung und der Absaugfilteranlage angeschlossen ist und so durch die Saugwirkung keine Gase austreten können. Der Unterdruck im Kessel verhindert eine Geruchsbelästigung in dieser Zeit. Das Sprühwasser bindet die im Tank vorhandenen Gase und/oder spült die Innenwände ab bevor die Wasserdampfreinigung beginn. Durch den Sprühkopf werden viele feine Strahlen und/oder ein Nebel erzeugt, so dass der Wasserverbrauch und damit die anfallende und zu entsorgenden Abwässer gering gehalten werden.Before the steam cleaning, the tank can be additionally rinsed with water or solvent from a spray device. This will be a Spray lance, with nozzles pointing upwards, inserted into the tank through a valve in the upper tank area. In order to avoid possible escape of gases, it is particularly advantageous if the tank is already connected to the collecting device and the Absaugfilteranlage and can escape through the suction no gas. The negative pressure in the boiler prevents odor nuisance during this time. The spray water binds the gases present in the tank and / or rinses off the inner walls before the steam cleaning begins. Through the spray head many fine rays and / or a mist are generated, so that the water consumption and thus the accumulated and to be disposed of wastewater are kept low.
Es können auch mehrere Tanks und/oder Tankkammern gleichzeitig an der Auffangvorrichtung angeschlossen werden und gleichzeitig und/oder zeitversetzt gereinigt und/oder getrocknet werden.It is also possible for several tanks and / or tank chambers to be connected to the collecting device at the same time and to be cleaned and / or dried simultaneously and / or with a time lag.

Um diese Produkte nach der Reinigung in Transportbehälter umfüllen zu können ist in der Kondensatbox 7 eine Heizung vorzugsweise eine Dampfheizung eingebaut.Depending on which products have been purged from the tank 1, it may be that the product crystallizes out in the condensate box, e.g. Phenols. In order to be able to transfer these products into the transport container after cleaning, a heater, preferably a steam heater, is installed in the condensate box 7.

Um einen Umfüllvorgang zu sparen kann zwischen die Auslassvorrichtung und der Kondensatbox eine Weiche 14 eingebaut werden. So ist es möglich die Produktreste direkt in einen Transportbehälter zu füllen, ohne den Umweg über die Kondensatbox. Die Weiche 14 kann so ausgelegt sein, dass Flüssigkeiten immer direkt in einen Transportbehälter fliesen und Dämpfe weiter zur Kondensatbox gesaugt werden um dort zu kondensieren oder das zur Trennung der Produkt Wasserkonzentrationen eine Umschaltung erfolgt. Z.B. nur Restprodukt in Transportbehälter und Wasser-Produktgemisch in Kondensatbox.
