Description

Die vorliegende Erfindung betrifft ein Verfahren zur Verlangsamung der Bildung von Verockerungen in Wasserfördersystemen, insbesondere Brunnensystemen sowie eine Vorrichtung, die insbesondere zur Ausführung des Verfahrens dient.The present invention relates to a method for slowing down the formation of blockages in water delivery systems, in particular well systems, as well as a device which is used in particular for carrying out the method.

Wasserfördersysteme, und insbesondere Brunnensysteme, weisen eine oft in sehr große Tiefen reichende Wasserförderleitung und eine das Wasser fördernde Pumpe auf, die das Wasser über die Wasserförderleitung aus dem Brunnen fördert. Ein großes Problem, das fast bei allen Brunnensystemen auftritt, sind Verockerungen, aufgrund eines hohen Eisen- und Mangangehaltes im strömenden Wasser. Dies führt zum Zuwachsen der Öffnungen der Filterstrecken, der Pumpe und/oder der Wasserförderleitung und zu einer entsprechenden Pumpenleistungsreduzierung. Verockerungen treten als fest anhaftende Verkrustungen auf, die in der Regel nur schwer löslich bzw. entfernbar sind.Water delivery systems, and in particular well systems, have a water delivery line, often at very great depths, and a pump that pumps the water and delivers the water out of the well via the water delivery line. A major problem that occurs in almost all well systems are obstructions due to high levels of iron and manganese in the flowing water. This leads to the growth of the openings of the filter sections, the pump and / or the water delivery line and to a corresponding pump power reduction. Obstructions occur as firmly adhering encrustations, which are generally difficult to dissolve or remove.

Dies hat zur Folge, dass Wasserförderleistungen rapide abnehmen können und aufwändige Instandhaltungsmaßnahmen notwendig sind, um die Förderung der gewünschten Wassermenge sicherzustellen. Die Aufwändigkeit ist bedingt durch die Notwendigkeit der Reinigung von Brunnenfiltern sowie den Ausbau und Instandsetzung, gegebenenfalls sogar Ersatz von Pumpen und sehr langen Wasserförderleitungen.As a result, water production rates are rapidly decreasing and costly maintenance is needed to ensure the desired amount of water is delivered. The complexity is due to the necessity of cleaning well filters and the removal and repair, possibly even replacement of pumps and very long water supply lines.

Die Ursachen für derartige Verockerungen sind weniger physikalischer/chemischer Natur, die Initialverockerungen darstellen, sondern überwiegend biologischer Natur. die auf die Initialverockerungen aufbauen. Wie aus Gerhard Krems, "Studie über die Brunnenalterung im Auftrag des Bundesministeriums des Inneren, Unterabteilung Wasserwirtschaft" vom Dezember 1972 hervorgeht und wie durch Untersuchungen des Anmelders bestätigt, ist der Grund für die Verockerungen hervorgerufen durch Eisen- und Manganspeichernde Bakterien, hauptsächlich durch die Eisenbakterien Gallionella und Leptothrix. Das im Wasser gelöste vorhandene zweiwertige Eisen und/oder zweiwertige Mangan wird von diesen Bakterien aufgenommen und in Form von unlöslichen Eisen- und Manganverbindungen wieder ausgeschieden (a. a. O., S. 41-42).The causes of such blockages are of a less physical / chemical nature, which are initial blockages, but predominantly biological in nature. which build on the Initialverockerungen. How out Gerhard Krems, "Study on the well aging on behalf of the Federal Ministry of the Interior, Subdivision Water Management" of December 1972 The reason for the blockages is caused by iron and manganese-storing bacteria, mainly by the iron bacteria Gallionella and Leptothrix. The existing divalent iron and / or divalent manganese dissolved in the water is taken up by these bacteria and in the form excreted again from insoluble iron and manganese compounds (loc. cit., pp. 41-42).

Im Stand der Technik sind eine Mehrzahl von Maßnahmen sowohl zur Verhinderung von Verockerungen als auch vermehrt zur Bereinigung von Verockerungen bekannt geworden, welche jedoch nicht zu langfristig zufriedenstellenden Ergebnissen geführt haben. So gibt die vorstehende Studie (a. a. O., S. 51-52 Nr. 7) an, dass die Verockerung durch Verwendung von keimabtötenden Mitteln stark gebremst bzw. verhindert werden konnte. Bei diesen keimabtötenden Mitteln handelt es sich im Wesentlichen um Chlor, das dem im Brunnenrohr stehenden Wasser zugesetzt wird. Wie bekannt, ist jedoch das Vorhandensein von Chlor im Trinkwasser für dessen geschmackliche Verzehrqualität äußerst nachteilig. Zudem sind eine gezielte Dosierung und der dortige Verbleib von Chlor oder anderen chemischen Mitteln an den erwünschten Stellen in Brunnensystemen durch vertikale und horizontale Strömungsbewegungen des Grundwassers nicht möglich. Darüber hinaus greift Chlor ab bestimmten Konzentrationen metallische Bauteile von Brunnensystemen an.In the prior art, a variety of measures have been known both for the prevention of blockages and increasingly for the correction of blockages, which, however, have not led to long-term satisfactory results. For example, the above study (supra, pp. 51-52, No. 7) indicates that the oozing could be severely curbed or prevented by using germicidal agents. These germicidal agents are essentially chlorine, which is added to the water in the well pipe. As is known, however, the presence of chlorine in drinking water is extremely detrimental to its flavor quality of consumption. In addition, a targeted dosage and the local whereabouts of chlorine or other chemical agents at the desired locations in well systems by vertical and horizontal flow movements of the groundwater are not possible. In addition, at certain concentrations, chlorine attacks metallic components of well systems.

Als eine Möglichkeit der Verhinderung biologischer Verockerung von Brunnen wird gemäß EP 0 754 837 A2 eine Bestrahlung vorgeschlagen, die aus einer radioaktiven Strahlung besteht. Über die Akzeptanz radioaktive Strahlung in der Bevölkerung braucht hier nicht weiter diskutiert zu werden.As a possibility of prevention of biological oozing of wells according to EP 0 754 837 A2 proposed an irradiation, which consists of a radioactive radiation. The acceptance of radioactive radiation in the population need not be discussed further here.

Die DE 1 031 227 betrifft ein Verfahren zur Wiederherstellung verockerter Rohrbrunnen mittels schwingungserzeugter Druckwellen, also nicht die Verhinderung bzw. Verlangsamung der Verockerung, sondern deren nachträgliche Entfernung.The DE 1 031 227 relates to a method for restoring obstructed tube wells by means of vibration-generated pressure waves, ie not the prevention or slowing of the ochering, but their subsequent removal.

Auch die DE 29 28 998 C2 betrifft ein Verfahren und eine Vorrichtung zur Entockerung von Filterrohren von Wasserbrunnen mittels Gleichstrombeaufschlagung. Wie Versuche mit geophysikalischen Messungen des Anmelders zeigten, werden hierbei lediglich die Redoxbedingungen geringfügig verändert. Eine wesentliche Einschränkung des Stoffwechsels der Eisenbakterien kann hierdurch nicht erreicht werden. Gemäß DE 33 33 842 A1 wird eine Enteisungs- und Entmanganungsanlage für Brunnensysteme vorgeschlagen, bei der mittels Druckluft die Verockerungen wieder gelöst werden sollen.Also the DE 29 28 998 C2 relates to a method and a device for the discharge of filter tubes from water wells by means of direct current application. As experiments with geophysical measurements of the applicant showed, only the redox conditions are slightly changed. A substantial restriction of the metabolism of the iron bacteria can not be achieved thereby. According to DE 33 33 842 A1 a de-icing and demineralization system for well systems is proposed, in which compressed air is used to loosen the stains.

Die DE 40 10 943 A1 beschreibt ein Verfahren zur Verhinderung von Verockerungserscheinungen, Belagbildung und Verkrustung, was durch Aufbringung eines anodischen Stromes aus einer Gleichspannungsquelle erfolgen soll. Auch hier werden lediglich die Redoxbedingungen geringfügig verändert, Eine wesentliche Einschränkung des Stoffwechsels der Eisenbakterien kann hierdurch nicht erreicht werden.The DE 40 10 943 A1 describes a method for preventing oozing phenomena, deposit formation and encrustation, which is to take place by application of an anodic current from a DC voltage source. Again, only the redox conditions are slightly changed, a significant restriction of the metabolism of iron bacteria can not be achieved.

Die DE 43 20 414 A1 schlägt eine Vorrichtung zur Vermeidung von Verockerungen in Pumpenanlagen vor, bei der eine mit Permanentmagneten bestückte Magnetisierungslanze dem Ansaugbereich einer Pumpe vorgeschaltet und mit diesem zu einer anlagetechnischen Einheit zusammengefasst ist.The DE 43 20 414 A1 proposes a device for avoiding blockages in pump systems, in which a magnetizing lance equipped with permanent magnets is connected upstream of the suction region of a pump and combined with it to form a plant-technical unit.

Auch das deutsche Gebrauchsmuster DE 295 18 229 U1 befasst sich mit einer Anordnung zur Regenerierung verockerter Trinkwasserbrunnen, also zur nachträglichen Behebung von Verockerungen und nicht zu deren Verhinderung.Also the German utility model DE 295 18 229 U1 deals with an arrangement for the regeneration of dirty drinking water wells, so the subsequent elimination of blockages and not to prevent them.

Die EP 0 778 393 A2 beschreibt ein Verfahren und eine Vorrichtung zur Erhaltung der Leistungsfähigkeit neuer Brunnen sowie zur Reinigung und Regenerierung bestehender Brunnen mittel Ultraschall. Auch hierbei handelt es sich um eine nachträgliche Entfernung von Verockerungen durch Schwingungsanregung, wobei diese Technik nicht zu nachhaltig gewünschten Resultaten führt.The EP 0 778 393 A2 describes a method and apparatus for maintaining the performance of new wells and for cleaning and regenerating existing wells using ultrasound. Again, this is a subsequent removal of blockages by vibration excitation, this technique does not lead to sustainable desired results.

Lediglich den polarisierten elektrochemischen Verockerungsprozessen entgegenwirkende Maßnahmen zeigt die DE 103 06 119 A1 mittels Anschluss einer Titankatode, welche ersichtlich die biologischen Verockerungen nicht verhindern kann.Only the polarized electrochemical Verockerungsprozessen counteracting measures shows the DE 103 06 119 A1 by connecting a titanium cathode, which can not be seen to prevent the biological blockages.

Die o. g. Verfahren beschäftigen sich somit im Wesentlichen mit der nachträglichen Entfernung von eingetretenen Verockerungen. Ein funktionierendes vorbeugendes Verfahren, welches das zu fördernde Wasser nicht nachteilig beeinflusst, existiert derzeit nicht. Insbesondere existiert zur Zeit kein Verfahren, welches die nach der chemischen Initialverockerung ansetzende biologische Verockerung verhindert oder verlangsamt.The above-mentioned methods thus essentially deal with the subsequent removal of occlusions that have occurred. A functioning preventative process, which does not adversely affect the water to be pumped, currently does not exist. In particular, at the moment there is no method which according to the Preventive or slowing down of chemical initial staining.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Verlangsamung der Bildung von Verockerungen in Wasserfördersystemen, insbesondere Brunnensystemen vorzuschlagen, wodurch die Leistungsfähigkeit der Wasserfördersysteme erheblich gesteigert werden kann und die zu ergreifenden Maßnahmen auf relativ einfache Weise realisiert werden können.The present invention is therefore based on the object of proposing a method and a device for slowing down the formation of blockages in water delivery systems, in particular well systems, whereby the performance of the water supply systems can be significantly increased and the measures to be taken can be implemented in a relatively simple manner.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 bzw. des Anspruchs 4 gelöst.This object is solved by the features of claim 1 and of claim 4.

Erfindungsgemäß werden mit einem Frequenzgenerator Frequenzen zwischen 100 kHz und 25 MHz erzeugt, und diese Frequenzen zumindest einer Wechselstromsonde übermittelt, wobei mittels der zumindest einen Wechselstromsonde die Verockerungsbereiche im Brunnensystem, insbesondere in den Hauptzulaufbereichen zum Brunnen und/oder im Bereich der Pumpe und/oder der Wasserförderleitung des Wasserfördersystems, mit den durch den Frequenzgenerator erzeugten Frequenzen beaufschlagt werden.According to the invention, frequencies between 100 kHz and 25 MHz are generated by means of a frequency generator, and these frequencies are transmitted to at least one alternating-current probe, whereby by means of the at least one alternating-current probe the congestion areas in the well system, in particular in the main inlet areas to the well and / or in the area of the pump and / or the Water supply line of the water conveyor system, are acted upon by the frequencies generated by the frequency generator.

Gemäß der erfindungsgemäßen Vorrichtung ist die zumindest eine Wechselstromsonde im Brunnenfilter bzw. an oder in der Pumpe des Wasserfördersystems angeordnet und erzeugt Wechselstromfelder im Bereich des Wasserzulaufs des Brunnens bzw. der Pumpe.According to the device according to the invention, the at least one AC probe is arranged in the well filter or on or in the pump of the water delivery system and generates AC fields in the region of the water inlet of the well or the pump.

Durch Langzeitexperimente hat sich gezeigt, dass die bei dem untersuchten Brunnen vorgenommenen Maßnahmen zu einer erheblichen Verlangsamung der Verockerungen geführt haben. Mit großem Vorteil konnte dabei der Effekt erzielt werden, dass sich die abgelagerten Verockerungen einfach mechanisch lösen ließen, da die Erzeugung einer biologisch bedingten Verkrustung, wie bei herkömmlichen unbehandelten Brunnensystemen, nicht stattgefunden hat. Dies führt zu einer erheblichen Aufwandsverringerung bei der Instandhaltung der Brunnensysteme, weil einerseits die Instandhaltungsintervalle erheblich vergrößert werden können und andererseits nahezu keine biologisch bedingte Verkrustungen der Verockerungen mehr entstehen, was deren leichtes Ablösen ermöglicht.Long-term experiments have shown that the measures taken in the well studied have led to a significant slowdown in the osmotic process. With great advantage, the effect could be achieved that the deposited blockages could be easily solved mechanically, since the production of a biological conditional encrustation, as in conventional untreated well systems, has not occurred. This leads to a considerable reduction in the cost of maintenance of the well systems, because on the one hand the maintenance intervals can be considerably increased and on the other hand almost no biologically caused incrustations of the blockages more arise, which allows their easy detachment.

Vorteilhafterweise erfolgt das Durchfahren der beaufschlagten Frequenzen zyklisch, wodurch eine negative Beeinflussung der unterschiedlichen Bakterien ermöglicht wird.Advantageously, the passage through the applied frequencies cyclically, whereby a negative influence on the different bacteria is made possible.

Der Beaufschlagungszyklus beträgt dabei zwischen wenigen Millisekunden und mehreren Minuten. Da häufig verschiedene Bakterienarten an den Verockerungsprozessen beteiligt sind, können dadurch Einwirkzeit und Frequenz für jede einzelne Art optimiert angepasst werden.The loading cycle is between a few milliseconds and several minutes. Since different types of bacteria are often involved in the amelioration processes, thereby the time of action and frequency for each individual species can be optimized.

Erfindungsgemäß weist die Vorrichtung zur Verlangsamung der Bildung von Verockerungen in Wasserfördersystemen, insbesondere Brunnensystemen, welche einen Brunnenfilter, eine Wasserförderleitung und eine das Wasser fördernde Pumpe aufweisen, und welche insbesondere zur Durchführung des vorgenannten Verfahrens geeignet ist, einen Frequenzgenerator, der Frequenzen zwischen 100 kHz und 25 MHz erzeugt, auf und diese Frequenzen zumindest einer Wechselstromsonde zuführt, wobei die zumindest eine Wechselstromsonde am Brunnenfilter bzw. an oder in der Pumpe des Wasserfördersystems angeordnet ist und im Bereich des Wasserzulaufs des Brunnenfilters oder der Pumpe Wechselstromfelder erzeugt.According to the invention, the device for slowing down the formation of blockages in water delivery systems, in particular well systems, which have a well filter, a water delivery line and a water pump, and which is particularly suitable for carrying out the aforementioned method, a frequency generator, the frequencies between 100 kHz and 25 MHz generated, and these frequencies at least one AC probe supplies, wherein the at least one AC probe is disposed on the well filter or on or in the pump of the water conveyor system and generates AC fields in the region of the water inlet of the well filter or the pump.

Mit dieser Vorrichtung werden die oben genannten Vorteile verwirklicht.With this device, the above advantages are realized.

Vorteilhafterweise ist die zumindest eine Wechselstromsonde aus einer im Wesentlichen kreisförmig oder teilkreisförmig umlaufenden Sonde gebildet. Dabei erstreckt sie sich vorteilhafterweise innerhalb des Brunnenfilters oder um die Öffnungen der Pumpe herum, um einen möglichst großen Umfangsabschnitt der Wasserzuläufe zum Brunnen oder zur Pumpe zu beeinflussen.Advantageously, the at least one alternating current probe is formed from a substantially circular or partially circular circumferential probe. In this case, it advantageously extends within the well filter or around the openings of the pump in order to influence the largest possible peripheral portion of the water supply to the well or to the pump.

Weiterhin ist vorteilhaft, dass die zumindest eine Wechselstromsonde aus mehreren Teilsonden gebildet ist. Dies ermöglicht eine relativ sparsame Aufbauweise der zumindest einen Wechselstromsonde und deren Einwirkung auf gezielte Bereiche.Furthermore, it is advantageous that the at least one alternating-current probe is formed from a plurality of partial probes. This allows a relatively economical construction of the at least one AC probe and their action on specific areas.

Vorteilhafterweise ist zumindest eine weitere Wechselstromsonde an oder in der Steigleitung des Wasserfördersystems angeordnet. Damit kann die Bildung von Verockerungen in der Steigleitung ebenfalls verlangsamt werden und können die Steigleitungen nach Ausbau aufgrund verringerter Verkrustungen erheblich schneller und besser gereinigt werden.Advantageously, at least one further AC probe is arranged on or in the riser of the water conveyor system. This can be the formation of blockages in the riser are also slowed down and the risers can be cleaned much faster and better after expansion due to reduced encrustations.

Gegebenenfalls können weitere Wechselstromsonden zum Einsatz kommen, die an den verockerungsgefährdeten Stellen angeordnet werden, insbesondere im Brunnenfilter sowie im Pumpen- und Steigleitungsbereich.If necessary, further alternating current probes may be used, which are arranged at the points liable to be blocked, in particular in the well filter and in the pump and riser region.

In einer bevorzugten Ausführungsform ist der Frequenzgenerator über eine erste elektrische Verbindungsleitung mit der zumindest einen Wechselstromsonde und über eine zweite elektrische Verbindungsleitung mit der stromleitenden Rohrtour des Brunnenausbaus oder der Pumpe verbunden. Alternativ kann eine Erdung über einen Erdsprieß erfolgen. Damit wird vorteilhafterweise eine sichere Verbindung zwischen Frequenzgenerator und Wechselstromsonde geschaffen, wobei weitere Einflüsse von außen im Wesentlichen vermieden werden können. Dies ist besonders bei tiefen Brunnen bzw. Tiefbrunnen von Vorteil, wodurch deren Überwachung auf ein Minimales reduziert werden kann. Der Anschluss der Verbindungsleitungen erfolgt vorzugsweise absolut wasserdicht.In a preferred embodiment, the frequency generator is connected via a first electrical connection line with the at least one alternating current probe and via a second electrical connection line with the current-conducting tube tour of the well construction or the pump. Alternatively, a ground can be made via a Erdsprieß. This advantageously creates a secure connection between the frequency generator and the alternating-current probe, wherein further influences from the outside can be substantially avoided. This is particularly advantageous for deep wells or deep wells, whereby their monitoring can be reduced to a minimum. The connection of the connecting lines is preferably completely waterproof.

Alternativ kann die Wechselstromsonde quasi als eine Antenne im wässrigen Medium dienen, die die vom Frequenzgenerator erzeugten Frequenzen empfängt und weiterleitet.Alternatively, the AC probe may effectively serve as an antenna in the aqueous medium which receives and forwards the frequencies generated by the frequency generator.

Bei Verwendung von elektrischen Verbindungsleitungen hat sich vorteilhafterweise ergeben, dass eine besonders sichere Übertragung der Frequenzen bzw. eine sichere Verbindung des Frequenzgenerators mit der Wechselstromsonde durch Koaxialkabel, insbesondere wasserbeständige (seewasserbeständige) Koaxialkabel, erzielt wird. Weiterhin ist vorteilhaft, dass die Erzeugung der Frequenzen, die der zumindest einen Wechselstromsonde übermittelt werden, zyklisch erfolgt, d. h., dass zyklisch die unterschiedlichen erzeugten Frequenzen über die Wechselstromsonde auf die entsprechenden Bereiche aufgebracht werden.When using electrical connection lines has advantageously shown that a particularly secure transmission of the frequencies or a secure connection of the frequency generator with the AC probe by coaxial cable, in particular water-resistant (seawater resistant) coaxial cable is achieved. Furthermore, it is advantageous that the generation of the frequencies which are transmitted to the at least one alternating-current probe takes place cyclically, ie. h., That cyclically the different generated frequencies are applied via the AC probe to the corresponding areas.

Dabei beträgt die Dauer eines Zyklus' vorteilhafterweise zwischen wenigen Millisekunden und mehreren Minuten. Da häufig verschiedene Bakterienarten an den Verockerungsprozessen beteiligt sind, können dadurch Einwirkzeit und Frequenz für jede einzelne Art optimiert angepasst werden.The duration of a cycle is advantageously between a few milliseconds and several minutes. As often different types of bacteria in the Verockerungsprozessen In this way, exposure time and frequency can be optimized for each individual species.

In den Figuren sind gleiche Elemente mit den gleichen Bezugsziffern bezeichnet.In the figures, like elements are designated by the same reference numerals.

In Fig. 1 ist die erfindungsgemäße Vorrichtung zur Verlangsamung der Bildung von Verockerungen in Wassersystemen am Beispiel eines Brunnensystems mit Bezugsziffer 1 dargestellt. Die Vorrichtung 1 ist in einem Brunnen oder Brunnenausbau 2 angeordnet, der eine Bohrlochwand 4 aufweist. Von der Oberseite des Brunnenausbaus 2 ist ein Sperrrohr 5 eingeführt, das ein im oberen Bereich des Brunnenausbaus angeordnetes Vollrohr 7 umgibt. Das Sperrrohr 5 erstreckt sich entlang der Bohrlochwand 4.In Fig. 1 the device according to the invention for slowing down the formation of blockages in water systems is illustrated by the example of a well system with reference numeral 1. The device 1 is arranged in a well or well construction 2, which has a borehole wall 4. From the top of the well construction 2, a barrier tube 5 is inserted, which surrounds a arranged in the upper region of the well structure full pipe 7. The locking tube 5 extends along the borehole wall 4th

In dem Brunnen ist unterhalb des Vollrohres 7 ein Filterrohr 9 angeordnet, durch das Wasser in das Innere des Rohres eindringen kann. Dieses Filterrohr erschließt einen oder mehrere Grundwasserleitende Horizonte des Grundwasserleiters. Bei Betrieb der Pumpe im Brunnensystem werden die hydraulisch aktiven Zulaufbereiche dieser Grundwasserhorizonte aktiviert und das Grundwasser fließt aus dem Grundwasserleiter dem Brunnen zu.In the well below the full tube 7, a filter tube 9 is arranged, can penetrate through the water in the interior of the tube. This filter tube opens up one or more aquifers of the aquifer. When the pump is operated in the well system, the hydraulically active inlet areas of these groundwater horizons are activated and the groundwater flows from the aquifer to the well.

Zwischen Bohrlochwand 4 und den Rohren 7 und 9 befindet sich in üblicher Weise Filterkies 11. Das Filterrohr 9 sowie der im äußeren Ringraum befindliche Filterkies 11 verhindern dabei, dass Sand und andere im Grundwasserleiter befindliche Partikel mitgefördert werden.Between the borehole wall 4 and the tubes 7 and 9 is in the usual way filter gravel 11. The filter tube 9 and the filter ring located in the outer annulus 11th prevent sand and other particles in the aquifer from being carried.

Innerhalb der Rohre 7 und 9 ist mittig um eine Achse 14 eine Unterwasserpumpe 13 angeordnet, an die sich nach oben eine Steigleitung 3 als Wasserförderleitung anschließt, aus der gemäß Pfeil 19 eine Wasserableitung bei entsprechendem Unterwasserpumpenbetrieb erfolgt. Die Förderung des Wassers erfolgt in üblicher Weise über Pumpendruckstufen 17 in der Unterwasserpumpe 13, die in der Lage sind, das Wasser ausr ggflls. erhebliche Tiefe an die Oberfläche zu fördern.Within the tubes 7 and 9, an underwater pump 13 is arranged centrally about an axis 14, to which a riser 3 connects as a water delivery line, from which according to arrow 19, a water discharge takes place with appropriate underwater pump operation. The promotion of the water is carried out in the usual way via pump pressure levels 17 in the underwater pump 13, which are able, the water ausr ggflls. to promote considerable depth to the surface.

Zur Verlangsamung der Bildung von Verockerungen weist die erfindungsgemäße Vorrichtung einen Frequenzgenerator 23 auf, der Frequenzen zwischen 100 kHz und 25 MHz erzeugt und diese Frequenzen zumindest einer Wechselstromsonde 31 zuführt. Der Frequenzgenerator 23 ist vorteilhafterweise außerhalb des Brunnenschachts 2 und oberhalb der Geländeoberkante 21 angeordnet. Selbstverständlich besteht auch die Möglichkeit ihn versenkt in der Erde neben dem Brunnenausbau 2 anzuordnen.To slow down the formation of blockages, the device according to the invention has a frequency generator 23 which generates frequencies between 100 kHz and 25 MHz and supplies these frequencies to at least one alternating-current probe 31. The frequency generator 23 is advantageously arranged outside of the well shaft 2 and above the terrain upper edge 21. Of course, there is also the possibility of placing it sunk in the ground next to the well extension 2.

Wie aus Fig. 1 und 2 ersichtlich, ist die Wechselstromsonde 31 geteilt und weist zwei Teilwechselstromsonden auf, die beispielsweise halbkreisförmig (nicht dargestellt) ausgebildet sein können. Wie aus Fig. 2 deutlicher ersichtlich ist, befinden sich die Teilwechselstromsonden 31 in der Nähe des Pumpenzulaufs 15 der Unterwasserpumpe 13, der ein Einlaufsieb 33 aufweist, durch das der Wasserzufluss gemäß Pfeil 35 stattfindet. Alternativ können auch multible Sonden z.B. an den Hauptzulaufhorizonten des Brunnenfilters z.B. hängend oder mit nicht stromleitenden Halterungen fest (eine Art Zentrierung) installiert werden.How out Fig. 1 and 2 can be seen, the AC probe 31 is divided and has two partial AC current probes, which may be formed, for example semicircular (not shown). How out Fig. 2 It can be seen more clearly that the partial alternating current probes 31 are located in the vicinity of the pump inlet 15 of the underwater pump 13, which has an inlet sieve 33, through which the water inflow according to arrow 35 takes place. Alternatively, multible probes, for example, can be installed at the main inlet horizons of the well filter, eg suspended or with non-conductive supports (a kind of centering).

Aus den Figuren 1 und 2 ist ersichtlich, dass zwischen Frequenzgenerator 23 und Wechselstromsonde 31 eine erste Verbindungsleitung 27 vorgesehen ist, und aus der Verbindungsleitung 27 eine zweite Verbindungsleitung 29 zur Verbindung oder Pumpengehäuse bzw. Brunnenausbau, sofern stromleitend, vorgesehen ist. Der Frequenzgenerator wird seinerseits über eine Versorgungsleitung 25 mit entsprechender Energie, beispielsweise normalem Wechselstrom von 230 V/50 Hz, gespeist.From the FIGS. 1 and 2 It can be seen that between frequency generator 23 and AC probe 31, a first connecting line 27 is provided, and from the connecting line 27, a second connecting line 29 to the connection or pump housing or well extension, if current-conducting, is provided. The frequency generator is in turn fed via a supply line 25 with corresponding energy, for example, normal alternating current of 230 V / 50 Hz.

Mit dem vorliegenden Verfahren und der vorliegenden Vorrichtung wird somit eine Verlangsamung der Bildung von Verockerungen in Wasserfördersystemen, insbesondere vertikalen oder horizontalen Brunnensystemen erreicht, wodurch aufwändige Instandhaltungen deutlich reduziert werden können, wobei nicht nur eine Verlangsamung der Verockerungen erzielt wird, sondern auch das Ablösen der entstandenen Verockerungen an den einzelnen Komponenten wie Brunnenfilter, Pumpe und Steigrohre, erheblich einfacher erfolgen kann, da deutlich weniger Verkrustungen entstehen.Thus, with the present method and apparatus, there is a slowing of the formation of blockages in water delivery systems, in particular achieved vertical or horizontal well systems, which costly maintenance can be significantly reduced, which not only slows the Verockerungen is achieved, but also the detachment of the resulting obstructions on the individual components such as well filter, pump and risers, can be done much easier because much less Encrustations arise.
