Abstract

A dirt filter (9) is connected into a water-supply line (8), which filter has a mechanical filter element through which the water passes and which, on the side against which the water flows, is enclosed in a filter housing (9'). The filter housing (9') is connected, via a first controllable shut-off valve (10.1), to a first drainage-water flushing line (11.1) opening into a drainage-water channel (21), with the result that the filter element can be flushed free of dirt by opening the shut-off valve (10.1). In the course of the water-supply line (8), a pressure tank (20) is connected downstream of the dirt filter (9), water inflow being carried out in the upper tank part and water outflow being carried out in the lower tank part. The pressure tank (20) is connected, at the top, to a gas-outlet line (22) with a precision air-release valve (2) and, at the bottom, to a flushing line (18) which is connected, via a second controllable shut-off valve (10.2), to a second drainage-water flushing line (11.2) which likewise opens into the drainage-water channel (21). Impurities in the water which have not been retained in the dirt filter (9) are either deposited on the base of the pressure tank (20), from where they are floated out when the shut-off valve (10.2) is opened, or rise in the form of a gas into the gas-outlet line (22), where they are blown out by the air-release valve (2). <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zur Reinigung von Druckwasser in Wasserversorgungs-, insbesondere Hauswasserversorgungsinstallationen, wobei in eine Wasserversorgungsleitung ein Schmutzfilter eingeschaltet ist, der ein vom Wasser durchströmtes, auf der angeströmten Seite in ein Filtergehäuse eingeschlossenes mechanisches Filterelement aufweist.The invention relates to a device for cleaning pressurized water in water supply, in particular domestic water supply installations, wherein a dirt filter is switched on in a water supply line, which has a mechanical filter element through which water flows and which is enclosed in a filter housing on the inflow side.

Bei üblichen Vorrichtungen dieser Art ist der Schmutzfilter, zumeist ein FWS-Sichtschmutzfilter, in regelmäßigen Zeitabständen zu reinigen, andernfalls setzt sich am Filterelement zu viel Schmutz ab, so daß infolge des entsprechend dabei wachsenden Strömungswiderstandes die am Filterelement auftretende Druckdifferenz so groß wird, daß Schmutz durch das Filterelement hindurchgepreßt wird und in die Installation gelangt. - Die Reinigung des Schmutzfilters ist umständlich und aufwendig, da der Schmutzfilter dazu geöffnet und die Wasserversorgungsleitung beidseits des Schmutzfilters abgesperrt werden muß. Die regelmäßige Reinigung des Schmutzfilters wird daher, besonders bei Hauswasserversorgungsinstallationen, häufig oder sogar regelmäßig versäumt, so daß der Schmutzfilter seine Wirksamkeit verliert. Im übrigen ist ein solcher Schmutzfilter nur gegen Wasserverschmutzungen durch Feststoffe oberhalb einer filterspezifischen Korngröße wirksam. Feinerkörnige Verschmutzungen passieren das Filterelement und werden nicht ausgeschieden, ebensowenig wie im Wasser enthaltene Gase, wie beispielsweise Kohlensäure, Luft usw.In conventional devices of this type, the dirt filter, usually an FWS visual dirt filter, must be cleaned at regular intervals, otherwise too much dirt settles on the filter element, so that the pressure difference occurring on the filter element is so great due to the correspondingly increasing flow resistance is that dirt is pressed through the filter element and gets into the installation. - The cleaning of the dirt filter is cumbersome and complex, since the dirt filter has to be opened and the water supply line on both sides of the dirt filter has to be shut off. Regular cleaning of the dirt filter is therefore often or even regularly neglected, especially in domestic water supply installations, so that the dirt filter loses its effectiveness. Incidentally, such a dirt filter is only effective against water contamination from solids above a filter-specific particle size. Fine-grained contaminants pass through the filter element and are not excreted, just as little as gases contained in the water, such as carbon dioxide, air, etc.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so auszubilden, daß die Filterreinigung auf einfache Weise möglich und eine Abscheidung auch feinkörniger fester sowie gasförmiger Verunreinigungen erreicht wird.The invention has for its object to provide a device of the type mentioned in such a way that filter cleaning is possible in a simple manner and a separation of fine-grained solid and gaseous impurities is achieved.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß das Filtergehäuse unterhalb des Filterelements über ein erstes steuerbares Absperrventil an eine in einen Abwasserkanal mündende erste Abwasserspülleitung angeschlossen ist, daß ferner dem Schmutzfilter im Zuge der Wasserversorgungsleitung ein Druckbehälter nachgeschaltet ist, wobei der Wassereinlauf durch eine Einströmöffnung im oberen Behälterteil und der Wasserauslauf durch eine Ausströmöffnung im unteren Behälterteil erfolgt, und daß der Druckbehälter oberhalb der Einströmöffnung an eine Gasauslaßleitung mit darin angeordnetem Präzisionsentlüftungsventil sowie unterhalb der Ausströmöffnung an eine Spülleitung angeschlossen ist, die über ein zweites steuerbares Absperrventil mit einer zweiten, ebenfalls im Abwasserkanal mündenden Abwasserspülleitung verbunden ist.This object is achieved according to the invention in that the filter housing is connected below the filter element via a first controllable shut-off valve to a first waste water flushing line opening into a waste water channel, and further that a pressure vessel is connected downstream of the dirt filter in the course of the water supply line, the water inlet through an inflow opening in the upper part of the container and the water outlet through an outlet in the lower part of the container, and that the pressure vessel above the inflow opening is connected to a gas outlet line with a precision ventilation valve arranged therein, and below the outflow opening to a flushing line which is connected via a second controllable shut-off valve to a second sewage flushing line also opening in the sewer.

Wird das Absperrventil am Filtergehäuse geöffnet, so wird der am Filterelement hängen gebliebene grobe Schmutz vom Filterelement abgespült und durch die Abwasserspülleitung in den Abwasserkanal geschwemmt. Die regelmäßige Reinigung des Schmutzfilters kann daher allein durch regelmäßiges Öffnen des Absperrventils erfolgen, ohne daß dazu die Wasserversorgungsleitung am Filter geschlossen zu werden braucht. Wird das Absperrventil automatisch gesteuert, findet die Filterreinigung regelmäßig und ohne jeden persönlichen Aufwand statt. Trotzdem noch das Filterelement passierende Stoffe werden im Druckbehälter abgeschieden. Durch die Größe des Druckbehälters ist die Wasserströmung im Druckbehälter äußerst gering, so daß in dem zur Ruhe gekommenen Wasser alle noch in den Druckbehälter gelangenden Feststoffverunreinigungen auf den Behälterboden absinken können, von wo sie durch die Spülleitung beim Öffnen des darin angeordneten Absperrventils ebenfalls in den Abwasserkanal ausgeschwemmt werden, was bei automatischer Steuerung auch dieses Absperrventils ebenfalls regelmäßig und ohne persönlichen Aufwand stattfinden kann. Die gasförmigen Verunreinigungen schließlich steigen im Druckbehälter aufwärts in die Gasauslaßleitung und werden durch das Präzisionsentlüftungsventil abgeblasen. Das auf diese Weise von Feststoffen und Gasen gereinigte Wasser fließt aus dem Druckbehälter in die Hausinstallation ab.If the shut-off valve on the filter housing is opened, the coarse dirt caught on the filter element is rinsed off the filter element and washed into the sewer through the sewage flushing line. Regular cleaning of the dirt filter can therefore only be done by opening the shut-off valve regularly, without having to close the water supply line on the filter. If the shut-off valve is controlled automatically, the filter cleaning takes place regularly and without any personal effort. However, substances that still pass through the filter element are separated in the pressure vessel. Due to the size of the pressure vessel, the water flow in the pressure vessel is extremely low, so that in the water that has come to rest, all solid contaminants that still get into the pressure vessel can sink to the bottom of the vessel, from where they also enter the sewer through the flushing line when the shut-off valve arranged therein is opened be flushed out, which can also take place regularly and without personal effort with automatic control of this shut-off valve. Finally, the gaseous impurities rise in the pressure vessel into the gas outlet line and are blown off by the precision vent valve. The water cleaned of solids and gases in this way flows out of the pressure vessel into the house installation.

Eine bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, daß in den auf den Druckbehälter folgenden Teil der Wasserversorgungsleitung ein Kontrollfilter eingeschaltet ist, der ein vom Wasser durchströmtes, auf der angeströmten Seite in ein Filtergehäuse eingeschlossenes und der Sichtkontrolle von außen zugängliches Filterelement aufweist, wobei das Filterhäuse unterhalb des Filterelements über ein drittes steuerbares Absperrventil an eine dritte, im Wasserkanal mündende Abwasserspülleitung angeschlossen ist. Dieser Kontrollfilter dient mit der Möglichkeit der Sichtkontrolle des Filterelements lediglich der Kontrolle der Wirksamkeit der erfindungsgemäßen Vorrichtung, wobei auch hier das Filterelement einem automatischen Reinigungsvorgang unterworfen werden kann, um jederzeit seine Wirksamkeit voll zu gewährleisten. Solange sich am Filterelement keine erkennbaren Verschmutzungen absetzen, arbeitet die Filtervorrichtung in gewünschter Weise. Zweckmäßigerweise ist der Kontrollfilter mit einem Präzisionsentlüftungsventil ausgestattet, was eine Kontrolle auch bezüglich der Entgasungswirkung erlaubt.A preferred embodiment of the invention is characterized in that a control filter is switched on in the part of the water supply line following the pressure container, which has a filter element through which the water flows and which is enclosed in a filter housing on the inflow side and accessible from the outside, the filter housing is connected below the filter element via a third controllable shut-off valve to a third wastewater flushing line that opens into the water channel. With the possibility of visual inspection of the filter element, this control filter merely serves to check the effectiveness of the device according to the invention, the filter element here also being able to be subjected to an automatic cleaning process in order to ensure its effectiveness at all times. As long as no recognizable soiling settles on the filter element, the filter device works in the desired manner. The control filter is expediently equipped with a precision ventilation valve, which also allows control with regard to the degassing effect.

Es empfiehlt sich, daß die Gasauslaßleitung an der höchsten und die Spülleitung an der tiefsten Stelle des Druckbehälters angesetzt sind, um einerseits Gasblasen, andererseits Schmutzansammlungen im Druckbehälter auszuschließen.It is recommended that the gas outlet line be placed at the highest and the purge line at the lowest point of the pressure vessel in order to exclude gas bubbles on the one hand and dirt accumulations in the pressure vessel on the other.

Der Aufbau eines unzulässigen Überdrucks im System kann in einfacher Weise dadurch vermieden werden, daß in der Gasauslaßleitung zwischen dem Präzisionsentlüftungsventil und dem Druckbehälter ein Überdrucksicherheitsventil mit einem Überaufstutzen vorgesehen ist, der in eine in den Abwasserkanal führende Überlaufleitung mündet.The build-up of an impermissible overpressure in the system can be avoided in a simple manner by providing an overpressure safety valve with an over-spigot in the gas outlet line between the precision vent valve and the pressure vessel Waste water duct leading overflow line opens.

Rückströmungen können in der Vorrichtung in üblicher Weise dadurch verhindert werden, daß in der Wasserversorgungsleitung je ein KFR-Ventil der Einströmöffnung des Druckbehälters vor-, bzw. seiner Ausströmöffnung nachgeschaltet ist, und zwar in Fließrichtung des Wassers nach dem der Einströmöffnung vor-, bzw. vor dem der Ausströmöffnung nachgeschalteten Filter.Backflows can be prevented in the device in the usual way that in the water supply line a KFR valve is arranged upstream of the inflow opening of the pressure vessel or downstream of its outflow opening, namely in the flow direction of the water after that upstream of the inflow opening. in front of the filter downstream of the outflow opening.

Die steuerbaren Absperrventile sind vorzugsweise als automatisch nach einem Zeitplan gesteuerte Magnetventile ausgebildet.The controllable shut-off valves are preferably designed as solenoid valves controlled automatically according to a schedule.

Im folgenden wird die Erfindung an einem in der Zeichnung dargestellten Ausführungsbeispiel näher erläutert. Die einzige Figur zeigt in teils schematischer Darstellung den Aufbau einer Vorrichtung zur Reinigung von Druckwasser in einer Hauswasserversorgungsinstallation.The invention is explained in more detail below using an exemplary embodiment shown in the drawing. The single figure shows a schematic representation of the structure of a device for cleaning pressurized water in a domestic water supply installation.

In der Zeichnung ist mit 7 ein Montageblock bezeichnet, dem aus einer nicht dargestellten Hauptwasserversorgungsleitung Wasser in Richtung des Pfeiles 15.1 zuströmt und aus dem das Wasser in Richtung des Pfeiles 15.2 zu einer ebenfalls nicht dargestellten Hauswasserversorgungsinstallation abströmt. Je nach Einstellung der drei im Montageblock 7 befindlichen Absperrventile kann das Wasser den Montageblock 7 direkt durchströmen oder, was den Regelbetriebsfall darstellt, in eine Wasserversorgungsleitung 8 umgelenkt werden, wenn das mittlere Absperrventil 7' des Montageblocks 7 geschlossen und die beiden endseitigen Absperrventile 7'' geöffnet sind. In die in Strömungsrichtung an den Montageblock 7 anschließende Wasserversorgungsleitung 8 ist ein FWS-Sichtschmutzfilter 9 eingeschaltet, der ein vom Wasser durchströmtes, auf der angeströmten Seite in ein Filtergehäuse 9' eingeschlossenes, in der Zeichnung nicht erkennbares mechanisches Filterelement aufweist. Das Filtergehäuse 9' ist unterhalb des Filterelements über ein erstes steuerbares Absperrventil 10.1 an eine in einen Abwasserkanal 21 mündende erste Abwasserspülleitung 11.1 angeschlossen. Das Absperrventil 10.1 ist als Magnetventil ausgebildet. Dem Schmutzfilter 9 ist im weiteren Zuge der Wasserversorgungsleitung 8 hinter einem KFR-Ventil 12.1 über eine Verschraubung 13.1 ein Druckbehälter 20 nachgeschaltet, wobei der Wassereinlauf aus der Wasserversorgungsleitung 8 durch eine Einströmöffnung 20.1 im oberen Behälterteil und der Wasserauslauf in den dem Druckbehälter 20 nachgeschalteten Teil der Wasserversorgungsleitung 8 durch eine Ausströmöffnung 20.2 im unteren Behälterteil erfolgt. Die Einströmöffnung 20.1 liegt im oberen Drittel, die Ausströmöffnung 20.2 im unteren Drittel des Druckbehälters 20. Oberhalb der Einströmöffnung 20.1, nämlich an der höchsten Stelle des Druckbehälters 20, ist dieser an eine Gasauslaßleitung 22 angeschlossen, in der sich ein unter dem Handelsnamen Tubra-Siko-mat erhältlicher Block 3 mit einem Überdrucksicherheitsventil und einem Manometer 4 befindet, wobei das Überdrucksicherheitsventil einen Überlaufstutzen 23 besitzt, der offen in einen Trichter 5 an einer in den Abwasserkanal 21 führenden Überlaufleitung 6 mündet. Der Block 3 ist weiter mit einem Präzisionsentlüftungsventil 2 ausgestattet. An das Entlüftungsventil 2 schließt sich noch eine durch ein steuerbares Magnetventil 24 schließbare Entgasungsleitung 25 an, die in die freie Atmosphäre mündet. Unterhalb der Ausströmöffnung 20.2, und zwar im Boden an seiner tiefsten Stelle ist der Druckbehälter 20 an eine Spülleitung 18 angeschlossen, die über ein zweites steuerbares Absperrventil 10.2, nämlich wiederum ein Magnetventil, mit einer zweiten, ebenfalls im Abwasserkanal 21 mündenden Abwasserspülleitung 11.2 verbunden ist. Zwischen dem Druckbehälter 20 und diesem steuerbaren Absperrventil 10.2 ist ein von Hand zu betätigender Kugelhahn 16 eingeschaltet. An die Ausströmöffnung 20.2 des Druckbehälters 20 schließen im weiteren Verlauf der Wasserversorgungsleitung 8 über eine Verschraubung 13.2. und ein KFR-Ventil 12.2 ein Kontrollfilter 17 an, der den gleichen Aufbau wie der FWS-Sichtschmutzfilter 9 besitzt. Bei diesem Kontrollfilter 17 ist das das Filterelement einschließende Filtergehäuse 17' unterhalb des Filterelementes über ein drittes steuerbares Absperrventil 10.3 an eine dritte, im Abwasserkanal 21 mündende Abwasserleitung 11.3 angeschlossen. Der Kontrollfilter 17 ist im übrigen ebenfalls mit einem Präzisionsentlüftungsventil 26 ausgestattet.In the drawing, 7 denotes a mounting block, from which water flows in the direction of arrow 15.1 from a main water supply line (not shown) and from which the water flows out in the direction of arrow 15.2 to a house water supply installation (also not shown). Depending on the setting of the three shut-off valves in the assembly block 7, the water can flow directly through the assembly block 7 or, which is the normal operating case, can be diverted into a water supply line 8 when the middle shut-off valve 7 'of the assembly block 7 is closed and the two end shut-off valves 7'' open are. In the water supply line 8 adjoining the mounting block 7 in the flow direction, an FWS visual dirt filter 9 is connected, which has a mechanical filter element which is flowed through by the water and enclosed in a filter housing 9 'on the inflow side and cannot be seen in the drawing. The filter housing 9 'is connected below the filter element via a first controllable shut-off valve 10.1 to a first waste water flushing line 11.1 opening into a waste water channel 21. The shut-off valve 10.1 is designed as a solenoid valve. The dirt filter 9 is further connected in the course of the water supply line 8 behind a KFR valve 12.1 via a screw connection 13.1 a pressure vessel 20, the water inlet from the water supply line 8 through an inflow opening 20.1 in the upper part of the container and the water outlet in the part of the pressure vessel 20 downstream Water supply line 8 takes place through an outflow opening 20.2 in the lower part of the container. The inflow opening 20.1 is in the upper third, the outflow opening 20.2 in the lower third of the pressure container 20. Above the inflow opening 20.1, namely at the highest point of the pressure container 20, the latter is connected to a gas outlet line 22, in which there is a tube under the trade name Tubra-Siko block 3 available with an overpressure safety valve and a manometer 4 is located, the overpressure safety valve having an overflow nozzle 23 which opens openly into a funnel 5 at an overflow line 6 leading into the sewer 21. The block 3 is further equipped with a precision vent valve 2. The vent valve 2 is also connected to a valve 24 that can be closed by a controllable solenoid valve Degassing line 25, which opens into the free atmosphere. Below the outflow opening 20.2, namely in the bottom at its lowest point, the pressure vessel 20 is connected to a flushing line 18, which is connected via a second controllable shut-off valve 10.2, namely again a solenoid valve, to a second sewage flushing line 11.2 also opening into the sewer 21. Between the pressure container 20 and this controllable shut-off valve 10.2, a manually operated ball valve 16 is switched on. In the further course of the water supply line 8, a screw connection 13.2 connects to the outflow opening 20.2 of the pressure vessel 20. and a KFR valve 12.2 to a control filter 17, which has the same structure as the FWS visual dirt filter 9. In this control filter 17, the filter housing 17 'enclosing the filter element is connected below the filter element via a third controllable shut-off valve 10.3 to a third sewage line 11.3 opening into the sewer 21. The control filter 17 is also equipped with a precision vent valve 26.

Die Funktionsweise der Vorrichtung läßt sich kurz wie folgt beschreiben:
Das Wasser fließt in der Wasserversorgungsleitung 8 durch den FWS-Sichtschmutzfilter 9 und die Einströmöffnung 20.1 in den oberen Teil des mit einem Standfuß 19 versehenen Druckbehälters 20 ein. Grober Schmutz bleibt dabei am Filterelement des Schmutzfilters 9 hängen. Zu beliebigen oder nach einem Zeitplan vorgegebenen Zeitpunkten wird das Absperrventil 10.1 in der Abwasserspülleitung 11.1 geöffnet, so daß Wasser aus dem Filtergehäuse 9' in die Abwasserspülleitung 11.1 ausfließen kann, wobei sich innerhalb des Filtergehäuses 9' eine Wirbelströmung am Filterelement ergibt, die den Schmutz am Filterelement ab- und in die Abwasserspülleitung 11.1 ausspült. Im Druckbehälter 20 selbst wird das Wasser wegen der Behältergröße träge und verliert im wesentlichen seine Fließgeschwindigkeit. Im Druckbehälter 20 können dadurch restliche Verschmutzungsteilchen auf den Behälterboden absinken und durch die Spülleitung 18 ausgespült werden, wenn zu diesem Zweck das die Spülleitung 18 abschließende Absperrventil 10.2 wiederum zu beliebigen oder nach einem Zeitplan gesteuerten Zeiten geöffnet wird. Die im Wasser enthaltenen gasförmigen Beimengungen, wie insbes. aggressive Kohlensäure, steigen im Druckbehälter 20 nach oben und gelangen durch die Gasauslaßleitung 22 zum Entlüftungsventil 2, durch das sie in die Entgasungsleitung 25 abgeblasen werden. Mit Hilfe des in der Entgasungsleitung 25 vorgesehenen Magnetventils 24 besteht die Möglichkeit einer Kontrolle der Entgasungsfunktion Bleibt nämlich das Magnetventil 24 eine Zeit lang geschlossen, sammeln sich die abgeschiedenen Gasbestandteile in der Entgasungsleitung 25 vor dem Magnetventil 24 und strömen mit deutlichem Geräusch nach außen ab, wenn das Magnetventil 24 geöffnet wird. Das reine, saubere Wasser fließt über den Kontrollfilter 17 mit Präzisionsentlüftungsventil 26 ab. Die Vorrichtung arbeitet solange einwandfrei, wie sich am Filterelement des Kontrollfilters 17 keine Schmutzpartikel absetzen und am Präzisionsentlüftungsventil 26 keine Gase abgeblasen werden. Alle Magnetventile können durch eine in der Zeichnung nicht dargestellte zentrale Steuereinheit nach einem vorgegebenen Zeitplan gesteuert werden.The operation of the device can be briefly described as follows:
The water flows in the water supply line 8 through the FWS visual dirt filter 9 and the inflow opening 20.1 into the upper part of the pressure vessel 20 provided with a base 19. Coarse dirt gets caught on the filter element of the dirt filter 9. The shut-off valve 10.1 in the waste water flushing line 11.1. Is at any time or predetermined according to a schedule opened so that water can flow out of the filter housing 9 'into the waste water flushing line 11.1, a vortex flow resulting from the filter element within the filter housing 9', which rinses the dirt on the filter element and rinses it out into the waste water flushing line 11.1. In the pressure vessel 20 itself, the water becomes sluggish due to the size of the vessel and essentially loses its flow rate. In the pressure vessel 20, residual dirt particles can sink to the bottom of the vessel and be flushed out through the flushing line 18 if for this purpose the shut-off valve 10.2 closing the flushing line 18 is opened again at any time or according to a schedule. The gaseous admixtures contained in the water, in particular aggressive carbon dioxide, rise in the pressure vessel 20 and pass through the gas outlet line 22 to the vent valve 2, through which they are blown off into the degassing line 25. With the help of the solenoid valve 24 provided in the degassing line 25, there is the possibility of checking the degassing function. If the solenoid valve 24 remains closed for a while, the separated gas components collect in the degassing line 25 in front of the solenoid valve 24 and flow outward with a clear noise when the solenoid valve 24 is opened. The pure, clean water flows through the control filter 17 with a precision vent valve 26. The device works properly as long as no dirt particles settle on the filter element of the control filter 17 and no gases are blown off on the precision vent valve 26. All solenoid valves can be controlled according to a predetermined schedule by a central control unit, not shown in the drawing.
