Description

Beschreibungdescription
Vorrichtung zur Aufnahme von mit Feststoffen versetzten Flüssigkeiten sowie Vorrichtung zum Entfernen von Flüssigkeit aus einer derartigen AufnahmevorrichtungDevice for holding liquids mixed with solids and device for removing liquid from such a holding device
Die vorliegende Erfindung betrifft eine Vorrichtung zur Aufnahme von mit Feststoffen versetzten Flüssigkeiten, insbesondere zur Aufnahme von Abwasser aus Kernkraftwerken, mit einem einseitig offenen Körper, der einen Innenraum definiert.The present invention relates to a device for holding liquids mixed with solids, in particular for holding waste water from nuclear power plants, with a body that is open on one side and defines an interior space.
Die Erfindung betrifft weiter eine Vorrichtung zum Entfernen von Flüssigkeit aus einer Aufnahmevorrichtung mit einem Innenraum, einem Rohr, das mit dem Innenraum zum Abführen der Flüssigkeit in leitender Verbindung steht, sowie einem Deckel zur Auflage auf der Aufnahmevorrichtung, wobei der Deckel im Bereich des Innenraums eine Öffnung aufweist.The invention further relates to a device for removing liquid from a receptacle with an interior, a tube which is in conductive connection with the interior for discharging the liquid, and a lid for resting on the receptacle, the lid in the region of the interior Has opening.
Abwässer aus einer kerntechnischen Anlage können zur Entsor- gung eingedampft werden. Ein dafür geeignetes Verfahren und eine Vorrichtung sind beispielsweise aus der DE 31 14 060 AI bekannt.Waste water from a nuclear plant can be evaporated for disposal. A suitable method and a device are known for example from DE 31 14 060 AI.
Insbesondere werden derartige Vorrichtungen bei der Abwasser- behandlung in Kernkraftwerken eingesetzt, die eine möglichst genaue Reinigung erfordert. Das Abwasser wird zunächst zentrifugiert und anschließend verdampft. Hierbei wird bereits ein großer Teil von Feststoffen entzogen, die möglicherweise radioaktiv sind oder den Betrieb der Anlage behin- dern können. Das verbleibende, nicht vollständig saubere Abwasser wird in Tanks gelagert und fortlaufend umgewälzt. Das Umwälzen dient zum Vermeiden von Ablagerungen kleiner, noch im Abwasser enthaltener Partikel.In particular, such devices are used in wastewater treatment in nuclear power plants, which require the most accurate cleaning possible. The waste water is first centrifuged and then evaporated. A large part of the solids that may be radioactive or that can hinder the operation of the plant are already removed. The remaining, not completely clean wastewater is stored in tanks and continuously circulated. The circulation serves to avoid deposits of small particles still contained in the waste water.
Diese kleinen Partikel werden durch eine „Infaßtrocknung" mittels Unterdruck oder Vakuum entfernt. Beispielsweise ist dafür ein Verfahren aus der DE 42 01 841 Cl geeignet. In der Regel wird das mit Feststoffen versetzte Abwasser in ein Faß eingebracht. Dieses Faß wird luftdicht mit einer Abfüllhaube verbunden, wobei ein Klöpperboden der Abfüllhaube von oben auf das Faß aufgelegt wird. Der Klöpperboden weist eine kup- pelförmige Innenseite auf. Anschließend wird das Faß über die Abfüllhaube mit Unterdruck beaufschlagt, so daß die enthaltene Flüssigkeit verdampft und abgezogen werden kann. Aufgrund des Unterdrucks und des Verdampfens werden die Feststoffe aus dem Faß in Richtung Klöpperboden gerissen und legen sich dort an. Es bilden sich starke Ablagerungen, die beim Auswechseln des Fasses manuell entfernt werden müssen.These small particles are removed by “in-line drying” using a vacuum or vacuum. For example, a method from DE 42 01 841 Cl is suitable for this As a rule, the waste water mixed with solids is placed in a drum. This barrel is connected airtight to a filling hood, a dished bottom of the filling hood being placed on the barrel from above. The dome bottom has a dome-shaped inside. Subsequently, the barrel is pressurized via the filling hood so that the liquid contained can be evaporated and drawn off. Due to the negative pressure and evaporation, the solids are torn from the barrel towards the bottom of the dome and settle there. Heavy deposits form which must be removed manually when the barrel is replaced.
Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung zur Aufnahme von mit Feststoffen versetzten Flüssig- keiten sowie eine Vorrichtung zum Entfernen von Flüssigkeit aus einer Aufnahmevorrichtung bereitzustellen, die mit geringem Reinigungsaufwand über einen längeren Zeitraum eingesetzt werden können.The object of the present invention is therefore to provide a device for holding liquids mixed with solids and a device for removing liquid from a holding device, which can be used over a longer period of time with little cleaning effort.
Erfindungsgemäß wird diese Aufgabe bei einer Vorrichtung zur Aufnahme von mit Feststoffen versetzten Flüssigkeiten der eingangs genannten Art dadurch gelöst, daß der Körper mit einem Verlustblech mit einer Öffnung verschlossen ist. Beim Anlegen des Unterdrucks wird das Verlustblech nur an seiner dem Innenraum des Körpers zugewandten Seite verschmutzt. Diese Verschmutzung ist zuverlässig in dem Körper aufgenommen und muß daher nicht manuell entfernt werden. Ein Verschmutzen der Vorrichtung zum Entfernen von Flüssigkeit wird zuverlässig vermieden.According to the invention, this object is achieved in a device for receiving liquids containing solids of the type mentioned in the introduction in that the body is closed with an opening by means of a loss plate. When the negative pressure is applied, the loss plate is only soiled on its side facing the interior of the body. This pollution is reliably absorbed in the body and therefore does not have to be removed manually. Contamination of the device for removing liquid is reliably avoided.
Bei der oben beschriebenen Vorrichtung zum Entfernen von Flüssigkeit aus einer Aufnahmevorrichtung wird die Aufgabe erfindungsgemäß dadurch gelöst, daß der Deckel an seiner der Aufnahmevorrichtung zugewandten Seite mindestens eine Dich- tung zur Anlage an einem Verlustblech aufweist. Diese Dichtung verhindert das Einwandern von Feststoffen in den Zwischenraum zwischen dem Deckel und dem Verlustblech. Der De- ekel wird daher zuverlässig vor Verschmutzungen geschützt. Eine aufwendige manuelle Reinigung ist nicht mehr erforderlich.In the device for removing liquid from a holding device described above, the object is achieved according to the invention in that the cover on its side facing the holding device has at least one seal for contacting a loss plate. This seal prevents solids from migrating into the space between the cover and the loss plate. The de- Disgust is therefore reliably protected from contamination. Time-consuming manual cleaning is no longer necessary.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindungen gehen aus den abhangigen Ansprüchen hervor.Advantageous refinements and developments of the inventions emerge from the dependent claims.
Vorteilhaft ist d e Öffnung in der Mitte des Verlustblechs angeordnet. Dadurch w rd eine gleichmaßige Beaufschlagung des Innenraums des Korpers mit Unterdruck erreicht.The opening is advantageously arranged in the middle of the loss plate. This achieves a uniform application of negative pressure to the interior of the body.
In vorteilhafter Ausgestaltung weist das Verlustblech eine Wölbung auf. Die Wölbung ist der kuppelformigen Form des bekannten Klopperbodens nachempfunden und bewirkt ein zuverlas- siges Entfernen der Flüssigkeit. Weiter kann das Verlustblech aufgrund der Wölbung bei Kontakt mit dem Deckel einfach elastisch verformt und daher vorgespannt werden. Die an dem Deckel angeordnete Dichtung wird dann mit der Vorspannkraft belastet, so daß die Dichtwirkung verbessert wird. Eine Beein- trachtigung der Dichtwirkung durch die elastische Verformung des Verlustblechs ist aufgrund der Wölbung ausgeschlossen.In an advantageous embodiment, the loss plate has a curvature. The curvature is based on the dome-shaped shape of the well-known beater bottom and causes the liquid to be removed reliably. Furthermore, the loss plate can simply be elastically deformed due to the curvature when it comes into contact with the cover and can therefore be prestressed. The seal arranged on the cover is then loaded with the prestressing force, so that the sealing effect is improved. The curvature prevents the sealing effect from being affected by the elastic deformation of the loss plate.
Die Öffnung des Verlustblechs kann mit einer umlaufenden Verdickung, insbesondere einer Rippe, einem Steg oder einer Um- bordelung versehen sein. Diese Verdickung bewirkt ebenfalls eine Belastung der an dem Deckel angeordneten Dichtung, so daß die Dichtwirkung verbessert wird. Die Verdickung des Verlustblechs kann mit der Wölbung kombiniert werden.The opening of the loss plate can be provided with a circumferential thickening, in particular a rib, a web or a border. This thickening also causes a load on the seal arranged on the cover, so that the sealing effect is improved. The thickening of the loss plate can be combined with the curvature.
D e erfmdungsgemaße Vorrichtung zum Entfernen von Flüssigkeit kann zusammen mit einer Aufnahmevorrichtung eingesetzt werden, deren Korper bereits mit einem Verlustblech verschlossen ist. Alternativ ist die Verwendung eines getrennten Verlustblechs möglich, das erst beim Entfernen von Flussig- keit aus der Ausnahmevorrichtung an dem Deckel befestigt wird. Gemäß einer vorteilhaften Weiterbildung weist der Deckel eine weitere Dichtung an seinem Außenumfang zur Anlage an der Aufnahmevorrichtung auf. Diese weitere Dichtung verhindert das Eindringen von Umgebungsluft in die Aufnahmevorrichtung sowie das Austreten von Feststoffen aus der Aufnahmevorrichtung.The device according to the invention for removing liquid can be used together with a receiving device, the body of which is already closed with a loss plate. Alternatively, the use of a separate loss plate is possible, which is only attached to the cover when liquid is removed from the exception device. According to an advantageous further development, the cover has a further seal on its outer circumference for contact with the receiving device. This additional seal prevents the penetration of ambient air into the receiving device and the escape of solids from the receiving device.
Vorteilhaft weist die Vorrichtung eine Reinigungseinrichtung für ihren Innenraum auf. Dieser Innenraum steht durch die Öffnungen des Deckels und des Verlustblechs mit dem Innenraum der Aufnahmevorrichtung in Verbindung und kann daher durchThe device advantageously has a cleaning device for its interior. This interior is in communication with the interior of the receiving device through the openings in the cover and the loss plate and can therefore pass through
Feststoffe verschmutzt werden. Die Reinigungseinrichtung ermöglicht ein Entfernen dieser Feststoffe ohne manuelle Unterstützung.Solids are contaminated. The cleaning device enables these solids to be removed without manual assistance.
Nach einer vorteilhaften Ausgestaltung ist der Innenraum der Vorrichtung zum Entfernen von Flüssigkeit im wesentlichen zylindrisch ausgebildet. Wird die Reinigungseinrichtung im wesentlichen auf der Mittelachse dieses Zylinders angeordnet, so ist der Abstand zu den Seitenwänden des Innenraums stets gleich. Hierdurch wird eine gute Reinigungswirkung im gesamten Innenraum erreicht.According to an advantageous embodiment, the interior of the device for removing liquid is essentially cylindrical. If the cleaning device is arranged essentially on the central axis of this cylinder, the distance to the side walls of the interior is always the same. This achieves a good cleaning effect in the entire interior.
Nachstehend wird die Erfindung anhand von Ausführungsbeispielen näher beschrieben, die schematisch in der Zeichnung dar- gestellt sind. Dabei zeigt:The invention is described in more detail below with the aid of exemplary embodiments which are shown schematically in the drawing. It shows:
Figur 1 einen Längsschnitt durch erfindungsgemäße Vorrichtungen zum Aufnehmen und Entfernen von Flüssigkeit in erster Ausführungsform; Figur 2 eine Ansicht ähnlich Figur 1 in weiterer Ausführungsform; Figur 3 eine vergrößerte Darstellung der Einzelheit X aus1 shows a longitudinal section through devices according to the invention for receiving and removing liquid in the first embodiment; Figure 2 is a view similar to Figure 1 in another embodiment; Figure 3 is an enlarged view of the detail X from
Figur 2 ; und Figur 4 eine vergrößerte Darstellung der Einzelheit Y aus Figur 2. In Figur 1 ist schematisch eine Vorrichtung zur Aufnahme von mit Feststoffen versetzten Flüssigkeiten dargestellt, die als Faß 10 bezeichnet wird. Das Faß 10 weist einen im wesentlichen zylindrischen Körper 11 mit einem Innenraum 12 auf. Der Körper 11 ist mit einem gewölbten Verlustblech 13 verschlossen. Das Verlustblech 13 weist im Bereich einer Mittelachse 15 einer Öffnung 14 auf. Die Öffnung 14 des Verlustblechs 13 ist mit einer umlaufenden Verdickung 16 umgeben.Figure 2; and FIG. 4 shows an enlarged illustration of the detail Y from FIG. 2. FIG. 1 shows schematically a device for holding liquids containing solids, which is referred to as a barrel 10. The barrel 10 has a substantially cylindrical body 11 with an interior 12. The body 11 is closed with a curved loss plate 13. The loss plate 13 has an opening 14 in the region of a central axis 15. The opening 14 of the loss plate 13 is surrounded by a circumferential thickening 16.
Es ist weiter eine Vorrichtung zum Entfernen von Flüssigkeit aus einem Faß 10 dargestellt, die als Abfüllhaube 20 bezeichnet wird. Die Abfüllhaube 20 weist einen Deckel 21 zur Anlage an dem Faß 10 auf. An den Deckel 21 schließt sich ein Innenraum 25 an, der im wesentlichen zylindrisch ausgebildet ist. Der Deckel 21 weist im Bereich des Innenraums 25 eine Öffnung 24 auf. Von dem Innenraum 25 zweigt ein Brüdenrohr 22 zum Abführen von Flüssigkeiten ab. Zur Reinigung des Innenraums 25 dient eine Reinigungsvorrichtung 26, die im wesentlichen mittig in dem Innenraum 25 angeordnet ist.A device for removing liquid from a barrel 10 is also shown, which is referred to as a filling hood 20. The filling hood 20 has a lid 21 for contacting the barrel 10. An interior 25 adjoins the cover 21 and is essentially cylindrical. The cover 21 has an opening 24 in the region of the interior 25. A vapor tube 22 branches off from the interior 25 for the removal of liquids. A cleaning device 26, which is arranged essentially centrally in the interior 25, is used for cleaning the interior 25.
Um ein Verschmutzen des Deckels 21 zu vermeiden, weist dieser an seiner dem Faß 10 zugewandten Seite eine Dichtung 23 auf. Diese Dichtung 23 legt sich in erster Ausgestaltung an dem Verlustblech 13 eines Fasses 10 an. In anderer Ausgestaltung kann ein Verlustblech 13' verwendet werden, das getrennt von dem Faß 10 und der Abfüllhaube 20 ausgebildet ist. Dieses Verlustblech 13' wird an dem Deckel 21 der Abfüllhaube befestigt. Anschließend wird das Faß 10 mit der Abfüllhaube 20, verbunden. Hierbei wird gleichzeitig das Verlustblech 13' dichtend zwischen dem Deckel 21 und dem Faß 10 aufgenommen. Im Bereich der Öffnungen 14, 24 ist die Dichtung 23 vorgesehen. Am Außenumfang des Deckels 21 ist eine weitere Dichtung 29 angeordnet, die sich an dem Faß 10 anlegt.In order to avoid contamination of the cover 21, this has a seal 23 on its side facing the barrel 10. In a first embodiment, this seal 23 bears against the loss plate 13 of a barrel 10. In another embodiment, a loss plate 13 'can be used, which is formed separately from the barrel 10 and the filling hood 20. This loss plate 13 'is attached to the lid 21 of the filling hood. Then the barrel 10 is connected to the filling hood 20. At the same time, the loss plate 13 'is sealingly received between the cover 21 and the barrel 10. The seal 23 is provided in the region of the openings 14, 24. On the outer circumference of the lid 21, a further seal 29 is arranged, which rests on the barrel 10.
Die Figuren 2 bis 4 zeigen eine weitere Ausführungsform einer erfindungsgemäßen Abfüllhaube 20, an der ein Faß 10 angebracht ist. Das Verlustblech 13 ist zwischen dem Deckel 21 und dem Faß 10 aufgenommen. Innenseitig ist der Zwischenraum zwischen dem Verlustblech 13 und dem Deckel 21 über die Dichtung 23 abgedichtet. Wird ein Verlustblech 13 mit einer Wölbung verwendet, so kann der Deckel 21 auf das Verlustblech aufgedruckt werden und dieses elastisch verformen. Hierdurch wird die auf die Dichtung 23 wirkende Dichtkraft wesentlich erhöht .FIGS. 2 to 4 show a further embodiment of a filling hood 20 according to the invention, to which a barrel 10 is attached. The loss plate 13 is between the cover 21 and the barrel 10 added. The space between the loss plate 13 and the cover 21 is sealed on the inside by the seal 23. If a loss plate 13 with a curvature is used, the cover 21 can be printed on the loss plate and deform it elastically. As a result, the sealing force acting on the seal 23 is significantly increased.
Am Außenumfang des Verlustblechs 13 und des Deckels 21 sind weitere Dichtungen 29, 30 vorgesehen. Die Dichtung 30 ist hierbei als aufblasbare Dichtung ausgebildet und verhindert das Eindringen von Umgebungsluft in das Faß 10.Further seals 29, 30 are provided on the outer circumference of the loss plate 13 and the cover 21. The seal 30 is designed as an inflatable seal and prevents the penetration of ambient air into the barrel 10.
Zum Entfernen von Flüssigkeit aus dem Faß 10 wird der Innen- räum 25 der Abfullhaube 20 mit Unterdruck beaufschlagt. In dem Faß 10 befindliche Flüssigkeit verdampft und wird durch das Brudenrohr 22 abgeführt. Zum Ruckfuhren von eventuell anfallendem Konzentrat ist eine Konzentratleitung 28 vorgesehen.In order to remove liquid from the barrel 10, the interior 25 of the filler hood 20 is subjected to negative pressure. Liquid in the barrel 10 evaporates and is discharged through the vapor tube 22. A concentrate line 28 is provided for returning any concentrate that may occur.
Beim Verdampfen der Flüssigkeit wird ein Teil der Feststoffe aus dem Faß 10 mitgerissen. Diese Feststoffe legen sich an dem Verlustblech 13 oder im Innenraum 25 der Abfullhaube 20 an. Ein Eindringen der Feststoffe in den Zwischenraum zwi- sehen dem Verlustblech 13 und dem Deckel 21 wird durch die Dichtungen 23, 29, 30 zuverlässig vermieden.When the liquid evaporates, some of the solids are carried away from the barrel 10. These solids attach themselves to the loss plate 13 or in the interior 25 of the filler hood 20. Penetration of the solids into the intermediate space between the lost sheet 13 and the cover 21 is reliably avoided by the seals 23, 29, 30.
Es wird fortlaufend Unterdruck angelegt und Flüssigkeit aus dem Faß 10 entfernt. Durch ein Überwachen der bei jedem Anle- gen des Unterdrucks entfernten Flussigkeitsmenge kann derVacuum is continuously applied and liquid is removed from the barrel 10. By monitoring the amount of liquid removed each time the vacuum is applied, the
Flussigkeitsgehalt in dem Faß 10 bestimmt werden. Bei Erreichen oder Unterschreiten eines bestimmten Flussigkeitsgehalts wird keine weitere Flüssigkeit entfernt. Zu diesem Zeitpunkt haben sich Verschmutzungen an der dem Faß 10 zugewandten Sei- te des Verlustblechs 13 und im Innenraum 25 der Abfullhaube gebildet. Die Verschmutzungen am Verlustblech 13 sind nicht kritisch, da das Verlustblech 13 erfmdungsgemaß am Faß 10 verbleibt. Eine Reinigung des Verlustblechs 13 ist daher nicht erforderlich. Das Faß 10 wird zusammen mit dem Verlustblech 13 abgenommen und mit geeigneten, nicht näher dargestellten Mitteln verschlossen.Liquid content in the barrel 10 can be determined. No further liquid is removed when a certain liquid content is reached or fallen below. At this point, dirt has formed on the side of the loss plate 13 facing the barrel 10 and in the interior 25 of the filler hood. The dirt on the loss plate 13 is not critical, since the loss plate 13 according to the invention on the barrel 10 remains. A cleaning of the loss plate 13 is therefore not necessary. The barrel 10 is removed together with the loss plate 13 and closed with suitable means, not shown.
Zur Reinigung des Innenraums 25 der Abfüllhaube 20 dient die Reinigungseinrichtung 26, die eine Reihe von Düsen 27 aufweist. Der Innenraum 25 ist im wesentlichen zylindrisch ausgebildet. Der Abstand von den Düsen 26 bis zur Wand des In- nenraums 25 ist über die gesamte Länge des Innenraums gleich. An allen Stellen der Wand des Innenraums 25 trifft daher das aus den Düsen 27 austretende Reinigungsmittel mit demselben Druck auf. Hierdurch wird eine zuverlässige Reinigungswirkung erreicht.The cleaning device 26, which has a row of nozzles 27, is used to clean the interior 25 of the filling hood 20. The interior 25 is essentially cylindrical. The distance from the nozzles 26 to the wall of the interior 25 is the same over the entire length of the interior. The cleaning agent emerging from the nozzles 27 therefore hits the same pressure at all points on the wall of the interior 25. This achieves a reliable cleaning effect.
Vorteilhaft wird zum Reinigen des Innenraums 25 eine geeignete, nicht näher dargestellte Auffangvorrichtung von unten her an den Deckel 21 angesetzt. Verschmutzungen der Umgebung werden zuverlässig vermieden. Selbstverständlich kann die Reini- gung des Innenraums 25 auch bei angesetztem Faß 10 erfolgen. Eine aufwendige manuelle Reinigung ist nicht mehr erforderlich.To clean the interior 25, a suitable collecting device, not shown in detail, is advantageously attached to the cover 21 from below. Contamination of the environment is reliably avoided. Of course, the interior 25 can also be cleaned when the drum 10 is attached. Time-consuming manual cleaning is no longer necessary.
Das erfindungsgemäße Faß 10 sowie die erfindungsgemäße Ab- füllhaube 20 ermöglichen einen störungsfreien Betrieb mit geringem Reinigungsaufwand über einen längeren Zeitraum. The barrel 10 according to the invention and the filling hood 20 according to the invention enable trouble-free operation with little cleaning effort over a longer period of time.
