Description

Die Erfindung betrifft einen Elektrofilter zum Reinigen staubbeladener Abgase mit mehreren in einem Gehäuse angeordneten Reihen geerdeter Niederschlagselektroden und zwischen den Reihen der Niederschlagselektroden angeordneten, unter negativer Hochspannung stehenden, Sprühelektroden, nach dem Oberbegriff des Anspruchs 1.The invention relates to an electrostatic precipitator for cleaning dust-laden exhaust gases with a plurality of arranged in a housing rows of grounded collecting electrodes and arranged between the rows of collecting electrodes, under negative high voltage, spray electrodes, according to the preamble of claim 1.

Abgase, welche mit Staub und/oder Aerosol beladen sind, welche meist aus Verbrennungsprozessen stammen, werden häufig mit Elektrofiltern gereinigt. In Elektrofiltern werden die Staubpartikel durch die unter einer negativen Hochspannung stehenden Sprühelektroden zum überwiegenden Anteil negativ ionisiert. Die negativ geladenen Staubteilchen wandern an die positiv geladenen oder geerdeten Niederschlagselektroden und lagern sich dort im Laufe der Zeit in Form einer Staubschicht ab. Sowohl die Sprühelektroden, an welchen sich ebenfalls Staubschichten bilden, als auch die Niederschlagselektroden, werden periodisch, beispielsweise durch Klopfen, abgereinigt und der abfallende Staub beispielsweise in einem Staubsammeltrichter gesammelt und in entsprechenden Behältern der weiteren Entsorgung oder Wiederverwertung zugeführt.Exhaust gases, which are laden with dust and / or aerosol, which usually come from combustion processes, are often cleaned with electrostatic precipitators. In electrostatic precipitators, the dust particles are predominantly negatively ionized by the discharge electrodes, which are under a negative high voltage. The negatively charged dust particles migrate to the positively charged or earthed precipitation electrodes and deposit there in the course of time in the form of a dust layer. Both the spray electrodes, which also form dust layers, as well as the collecting electrodes are periodically, for example by knocking, cleaned and collected the falling dust, for example, in a dust collection hopper and fed in appropriate containers for further disposal or recycling.

Die Abreinigung der Niederschlagselektroden erfolgt meist durch periodische mechanische Schläge mithilfe entsprechender Abklopforgane, insbesondere Hämmern oder Stößeln. Dabei werden die einzelnen Niederschlagselektroden oder mehrere Niederschlagselektroden zusammengefasst über einen sogenannten Purzelhammer, der an einen entsprechenden Amboss schlägt, abgereinigt. Die entstehende Beschleunigung löst die anhaftenden Staubschichten ab.The cleaning of the collecting electrodes is usually carried out by periodic mechanical shocks using appropriate Abklopforgane, especially hammers or plungers. In this case, the individual collecting electrodes or several collecting electrodes are combined via a so-called Purzelhammer, which strikes a corresponding anvil, cleaned. The resulting acceleration replaces the adhering dust layers.

Die DE 447 137 offenbart eine Schüttelvorrichtung für Elektroden elektrischer Gasreinigungsanlagen, mit welcher Sprüh- und Niederschlagselektroden eines Elektrofilters zur Entfernung des an den Elektroden anhaftenden Staubes in Erschütterung gebracht werden. Die Schüttelvorrichtung weist einen unter Federwirkung stehenden Hebel auf, mit welchem eine Schüttelwelle in Drehschwingung versetzt wird.The DE 447 137 discloses a shaking device for electrodes of electrical gas cleaning plants, with which the spray and precipitation electrodes of an electrostatic precipitator are made to vibrate to remove the dust adhering to the electrodes. The shaking device has a spring acting under spring action, with which a shaking shaft is set in torsional vibration.

Eine Klopfeinrichtung für einen Elektrofilter ist beispielsweise aus der DE 1 112 499 , der DE 1 865 538 U oder der DE 101 24 871 C1 bekannt. Aus der DE 43 22 162 C1 ist ein Elektrofilter mit einem speziellen Antrieb einer horizontal angeordneten Hammerwelle bekannt geworden. Die DE 28 39 542 A1 beschreibt ein Elektrofilter mit einer mechanisch betätigbaren Klopfeinrichtung, wobei die Klopfelemente durch Scheibenisolatoren voneinander isoliert sind.A knocking device for an electrostatic precipitator is for example from the DE 1 112 499 , of the DE 1 865 538 U or the DE 101 24 871 C1 known. From the DE 43 22 162 C1 is an electrostatic precipitator with a special drive a horizontally arranged hammer shaft has become known. The DE 28 39 542 A1 describes an electrostatic precipitator with a mechanically operable knocking device, wherein the knocking elements are insulated from each other by disc insulators.

Seltener erfolgt die Abreinigung der Niederschlagselektroden von Elektrofiltern durch Schwingungsanregung, Ausklinkvorrichtungen, Vibratoren, mittels Bürsten oder Druckluft. Derartige Systeme sind beispielsweise aus der DE 38 37 439 A1 , der DE 103 00 549 A1 oder der DE 197 28 369 A1 bekannt.Less frequently, the precipitation electrodes of electrostatic precipitators are cleaned by vibration excitation, notching devices, vibrators, brushes or compressed air. Such systems are for example from the DE 38 37 439 A1 , of the DE 103 00 549 A1 or the DE 197 28 369 A1 known.

Neben den einer stärkeren Verschmutzung ausgesetzten Niederschlagselektroden legen sich auch an den Sprühelektroden entsprechende Staubschichten ab, weshalb auch die Sprühelektroden in entsprechenden zeitlichen Abständen abgereinigt werden müssen. Da die Sprühelektroden auf einer entsprechenden negativen Hochspannung liegen, müssen zwangsweise die Komponenten der Abreinigungseinrichtung für die Sprühelektroden entsprechend vom Erdpotential isoliert werden. Zu diesem Zweck wird bei Klopfabreinigungssystemen die getrennt von der Niederschlagselektroden-Klopfeinrichtung angeordnete Antriebsvorrichtung der Sprühelektroden-Klopfeinrichtung über einen Dreh- oder Durchführungsisolator in der Wellenzuführung isoliert. Der Drehisolator ist nach Möglichkeit außerhalb des Gasstromes angeordnet und teilweise mit Spülluft beaufschlagt um Verschmutzungen und daraus resultierende Überschläge bis hin zu einer Zerstörung zu vermeiden.In addition to the precipitation electrodes, which are exposed to greater contamination, corresponding dust layers are deposited on the discharge electrodes, which is why the discharge electrodes must also be cleaned at appropriate time intervals. Since the sputtering electrodes are at a corresponding negative high voltage, the components of the sputtering electrode cleaning device must necessarily be isolated from ground potential accordingly. For this purpose, in knock cleaning systems, the drive device of the spray electrode knocking device, which is separate from the collecting electrode knocking device, is insulated via a rotary or feedthrough insulator in the shaft feed. If possible, the rotary isolator is located outside the gas flow and is partially supplied with scavenging air in order to avoid soiling and resulting arcing up to destruction.

Nachteilig bei bekannten Elektrofiltern mit Niederschlagselektroden- und Sprühelektrodenabreinigungsvorrichtungen ist der hohe Aufwand, welcher durch die getrennten Antriebsvorrichtungen für die beiden Elektrodensysteme und der Aufwand für die Isolierung der Abreinigungseinrichtung für die Sprühelektroden entsteht.A disadvantage of known electrostatic precipitators with precipitation electrode and Sprühelektrodenabreinigungsvorrichtungen is the high cost, which is caused by the separate drive devices for the two electrode systems and the cost of the isolation of the cleaning device for the Sprühelektroden.

Darüberhinaus erhöhen die notwendigen Komponenten für die Abreinigung der Niederschlagselektroden und Sprühelektroden die Gesamtbaugröße des Elektrofilters. Dieser Nachteil wird dadurch noch weiters verstärkt, dass die Antriebsvorrichtung für die Niederschlagselektroden-Klopfeinrichtung entsprechend weit entfernt von der Antriebsvorrichtung für die Sprühelektroden-Klopfeinrichtung angeordnet wird, um etwaige Überschläge zwischen den auf unterschiedlichen Potentialen befindlichen Systemen sicher zu vermeiden.In addition, the necessary components for the cleaning of the collecting electrodes and the discharge electrodes increase the overall size of the electrostatic precipitator. This disadvantage is characterized still further reinforces that the driving device for the collecting electrode knocking device is arranged correspondingly far away from the drive device for the Sprühelektroden-knocking device in order to safely avoid any flashovers between the systems located at different potentials.

Die Aufgabe der vorliegenden Erfindung besteht daher in der Schaffung eines oben genannten Elektrofilters mit Abreinigungseinrichtungen für die Niederschlags- und Sprühelektroden, welches möglichst einfach, kostengünstig und platzsparend aufgebaut ist und eine effiziente Abreinigung der Niederschlagselektroden und Sprühelektroden zulässt.The object of the present invention is to provide an above-mentioned electrostatic precipitator with cleaning devices for the precipitation and discharge electrodes, which is constructed as simple, inexpensive and compact as possible and allows efficient cleaning of the collecting electrodes and discharge electrodes.

Nachteile bekannter Elektrofilter und deren Abreinigungsverfahren sollen vermieden oder zumindest reduziert werden.Disadvantages of known electrostatic precipitator and their Abreinigungsverfahren should be avoided or at least reduced.

Die erfindungsgemäße Aufgabe wird durch ein oben genanntes Elektrofilter gelöst, bei dem die Antriebsvorrichtung der Niederschlagselektroden-Klopfeinrichtung über zumindest einen isolierten Mitnehmer mit dem zumindest einen Abklopforgan der Sprühelektroden-Klopfeinrichtung gekoppelt ist. Erfindungsgemäß wird also die Niederschlagselektroden-Klopfeinrichtung mit der Sprühelektroden-Klopfeinrichtung gekoppelt, sodass nur für die Niederschlagselektroden-Klopfeinrichtung eine entsprechende Antriebsvorrichtung erforderlich ist. Die Konstruktion der Kopplung der Antriebsvorrichtung der Niederschlagselektroden-Klopfeinrichtung mit dem zumindest einen Abklopforgan der Sprühelektroden-Klopfeinrichtung über zumindest einen isolierten Mitnehmer ist relativ einfach zu realisieren und weist die für den Betrieb erforderliche Sicherheit und Robustheit auf. Wird die Antriebsvorrichtung der Niederschlagselektroden-Klopfeinrichtung betätigt um die entsprechenden Abklopforgane, insbesondere Hämmer, gegen die Niederschlagselektroden wirken zu lassen, können über den isolierten Mitnehmer die Abklopforgane für die Sprühelektroden betätigt werden, sodass auch diese auf die Sprühelektroden wirken und dadurch der Staubbelag abgeschleudert wird. Die Antriebsvorrichtung für die Sprühelektroden-Klopfeinrichtung kann entfallen, da die Betätigung der Abklopforgane, insbesondere Hämmer, der Sprühelektroden-Klopfeinrichtung indirekt durch die Antriebsvorrichtung der Niederschlagselektroden-Klopfeinrichtung erfolgt. Somit können die entsprechenden Komponenten, welche für den Antrieb der Abklopforgane der Sprühelektroden-Klopfeinrichtung erforderlich wären, entfallen und müssen auch keine Maßnahmen für deren elektrische Isolation gegen Erde vorgenommen werden. Damit können Kosten und Platzbedarf eingespart werden.The object according to the invention is achieved by an above-mentioned electrostatic precipitator in which the drive device of the collecting electrode knocking device is coupled to the at least one knocking element of the spraying electrode knocking device via at least one insulated driver. According to the invention, therefore, the collecting electrode knocking device is coupled to the spraying electrode knocking device, so that a corresponding drive device is required only for the collecting electrode knocking device. The construction of the coupling of the driving device of the collecting electrode knocking device with the at least one knocking member of the spraying electrode knocking device via at least one insulated driver is relatively easy to implement and has the safety and robustness required for operation. If the drive device of the collecting electrode knocking device is actuated to allow the corresponding knocking devices, in particular hammers, to act against the collecting electrodes, the knocking elements for the spraying electrodes can be actuated via the insulated carrier, so that these also act on the spraying electrodes and the dust covering is thereby thrown off. The drive device for the Sprühelektroden-knocking device can be omitted, since the operation of the Abklopforgane, in particular hammers, the Sprühelektroden-knocking device indirectly through the driving device of the collecting electrode knocking device takes place. Thus, the corresponding components, which would be required for driving the Abklopforgane the Sprühelektroden-knocking, eliminated, and must be made no measures for their electrical isolation from ground. This can save costs and space requirements.

Üblicherweise umfasst die Antriebsvorrichtung der Niederschlagselektroden-Klopfeinrichtung eine mit einem Antriebsmotor und einem zugehörigen Getriebe verbundene Antriebswelle. An dieser Antriebswelle ist das zumindest eine Abklopforgan der Niederschlagselektroden-Klopfeinrichtung angeordnet. Eine entsprechende Steuerung schaltet den Antriebsmotor zu gewissen Zeitpunkten ein, sodass das zumindest eine Abklopforgan zu diesen Zeiten betätigt und die Niederschlagselektroden dadurch abgereinigt werden.Typically, the driving device of the collecting electrode knocking means comprises a drive shaft connected to a drive motor and an associated gearbox. At least one Aböffpforgan the collecting electrode knocking device is arranged at this drive shaft. A corresponding controller switches on the drive motor at certain times, so that the at least one knock-off member is actuated at these times and the collecting electrodes are thereby cleaned.

Bei dieser Konstruktion ist es von Vorteil, wenn jeder isolierte Mitnehmer ebenfalls an der Antriebswelle der Niederschlagselektroden-Klopfeinrichtung angeordnet ist und durch die Bewegung der Antriebswelle der Niederschlagselektroden-Klopfeinrichtung mitnehmbar ist und über den Mitnehmer das zumindest eine Abklopforgan der Sprühelektroden-Klopfeinrichtung betätigbar ist. Wird also die Antriebswelle der Niederschlagselektroden-Klopfeinrichtung betätigt, wird auch jeder daran angeordnete isolierte Mitnehmer betätigt und wirkt so auf das jeweilige Abklopforgan für die Sprühelektroden. Somit erfolgt eine Betätigung der Abklopforgane der Sprühelektroden-Klopfeinrichtung immer dann automatisch, wenn die Niederschlagselektroden-Klopfeinrichtung betätigt wird. Eine eigene Antriebsvorrichtung für die Sprühelektroden-Klopfeinrichtung ist nicht erforderlich und somit auch nicht deren elektrische Isolation.In this construction, it is advantageous if each isolated driver is also arranged on the drive shaft of the collecting electrode knocking device and is entrained by the movement of the drive shaft of the collecting electrode knocking device and on the driver, the at least one Abklopforgan the Sprühelektroden-knocking device is actuated. Thus, if the drive shaft of the collecting electrode knocking device is actuated, each isolated carrier arranged thereon is actuated and thus acts on the respective knocking device for the spray electrodes. Thus, actuation of the knocking members of the spraying electrode knocking means is always automatic when the collecting electrode knocking means is operated. A separate drive device for the spray electrode knocking device is not required and therefore not their electrical insulation.

Vorteilhafterweise ist an der Antriebswelle der Niederschlagselektroden-Klopfeinrichtung ein Positionsgeber angeordnet, sodass die Antriebswelle und jeder daran angeordnete Mitnehmer nach Beendigung eines Abreinigungsvorgangs in eine definierte Ausgangsstellung bringbar ist. Nach dem Abreinigungsvorgang wird also eine vorgegebene Position der Antriebswelle erzielt. Insbesondere ist es von Vorteil, wenn jeder Mitnehmer im Wesentlichen senkrecht nach unten weist, wenn er nicht benötigt wird, sodass der Mitnehmer eine möglichst kleine Angriffsfläche für Staub bietet und keine Dauerisolationsfunktion übernehmen muss. Abgesehen von der unerwünschten Verschmutzung des Mitnehmers, könnte die isolierende Wirkung des Mitnehmers durch daran anhaftenden Staub unterbunden werden, wodurch es im Abreinigungsfall zu Überschlägen kommen könnte.Advantageously, a position sensor is arranged on the drive shaft of the collecting electrode knocking device, so that the drive shaft and each driver arranged thereon can be brought into a defined starting position after completion of a cleaning process. After the cleaning process so a predetermined position of the drive shaft is achieved. Especially It is advantageous if each driver points substantially vertically downwards when it is not needed, so that the driver provides as small a surface for dust as possible and does not need to take on a permanent insulation function. Apart from the undesirable contamination of the driver, the insulating effect of the driver could be prevented by adhering dust, which could lead to rollovers in Abreinigungsfall.

Gemäß einem weiteren Merkmal der Erfindung ist am freien Ende jedes Mitnehmers eine Mitnahmevorrichtung, beispielsweise eine drehbar gelagerte Rolle angeordnet, welche beim Kontakt mit dem zumindest einem Abklopforgan der Sprühelektroden-Klopfeinrichtung in Drehung versetzbar ist. Durch das Vorsehen einer solchen Mitnahmevorrichtung werden Reibungen zwischen dem isolierten Mitnehmer und dem Abklopforgan der Sprühelektroden-Klopfeinrichtung vermindert. Die Mitnahmevorrichtung, insbesondere die drehbar gelagerte Rolle rollt somit am Abklopforgan der Sprühelektroden-Klopfeinrichtung ab und betätigt dieses ohne Beeinträchtigung oder Zerstörung durch Reibung zu bewirken.According to a further feature of the invention, a driving device, for example a rotatably mounted roller is arranged at the free end of each driver, which in contact with the at least one Abklopforgan the Sprühelektroden-knocking device is set in rotation. By providing such a driving device, friction between the insulated driver and the knocking member of the spray electrode knocking device is reduced. The entrainment device, in particular the rotatably mounted roller thus rolls off the Abklopforgan the spray electrode knocking device and actuates this effect without affecting or destruction by friction.

Vorteilhaferweise sind mehrere Niederschlagselektroden, beispielsweise über eine Verbindungsschiene miteinander verbunden, wobei an dem Verbund mehrerer Niederschlagselektroden für jedes Abklopforgan der Niederschlagselektroden-Klopfeinrichtung ein Amboss angeordnet ist. Durch Klopfen des Abklopforgans auf den Amboss wird somit der gesamte Verbund der Niederschlagselektroden mit einem entsprechenden Impuls versehen, sodass der Staubbelag des gesamten Verbunds der Niederschlagselektroden von diesen abgeschleudert wird. Durch die Zusammenfassung mehrerer Niederschlagselektroden kann die Klopfeinrichtung entsprechend klein und platzsparend ausgeführt werden. Dies ist insbesondere für kleinere Elektrofilter von Vorteil.Advantageously, a plurality of collecting electrodes, for example, connected to one another via a connecting rail, wherein an anvil is arranged on the composite of a plurality of collecting electrodes for each Abklopforgan the collecting electrode knocking device. By knocking the abutment member on the anvil thus the entire composite of the collecting electrodes is provided with a corresponding impulse, so that the dust covering of the entire composite of the collecting electrodes is thrown off of these. By combining several collecting electrodes, the knocking device can be made correspondingly small and space-saving. This is particularly advantageous for smaller electrostatic precipitators.

Ebenso können mehrere Sprühelektroden über zumindest einen Rahmen und mehrere Sprühelektroden-Rahmen allenfalls über zumindest eine Verbindungsschiene miteinander verbunden sein, wobei an zumindest einem Sprühelektroden-Rahmen oder zumindest einer Verbindungsschiene für jedes Abklopforgan der Sprühelektroden-Klopfeinrichtung ein Amboss angeordnet ist. Auch hier kann mit einem Schlag jedes Abklopforgans auf einen zugehörigen Amboss gleich ein Verbund an Sprühelektroden abgeklopft werden.Likewise, a plurality of spray electrodes can at least be connected to one another via at least one frame and a plurality of spray electrode frames, wherein an anvil is arranged on at least one spray electrode frame or at least one connecting rail for each knocking member of the spray electrode knocking device. Again, you can join a blow of each Abklopforgans on an associated anvil equal to a composite of spray electrodes are knocked off.

Eine platzsparende Ausführungsvariante kann dadurch erzielt werden, dass jeder Sprühelektroden-Rahmen im Bereich der Sprühelektroden-Klopfeinrichtung eine entsprechende Einbuchtung aufweist. Die Abklopforgane für die Sprühelektroden sind somit neben der Einbuchtung des Sprühelektroden-Rahmens angeordnet, sodass die Außenabmessungen eines erfindungsgemäß gestalteten Elektrofilters nicht wesentlich von den Abmessungen eines Elektrofilters ohne Abreinigungsvorrichtung abweichen.A space-saving embodiment variant can be achieved in that each discharge electrode frame has a corresponding indentation in the region of the discharge electrode knocking device. The Abklopforgane for the spray electrodes are thus arranged adjacent to the indentation of the Sprühelektroden frame, so that the outer dimensions of an inventively designed electrostatic filter does not differ significantly from the dimensions of an electrostatic precipitator without cleaning device.

Dabei ist es von Vorteil, wenn die Sprühelektroden-Klopfeinrichtung im unteren Bereich des Sprühelektroden-Rahmens angeordnet ist und der Sprühelektroden-Rahmen in diesem unteren Bereich zusammenlaufend ausgebildet ist. Ohne das Gehäuse eines derartigen Elektrofilters verändern zu müssen, findet die Klopfeinrichtung für die Sprühelektroden neben dem zusammenlaufend ausgebildeten unteren Bereich des Sprühelektroden-Rahmens Platz.It is advantageous if the spray electrode knocking device is arranged in the lower region of the spray electrode frame and the spray electrode frame is designed to converge in this lower region. Without having to change the housing of such an electrostatic filter, the knocking device for the spray electrodes is located next to the converging lower region of the spray electrode frame.

Die vorliegende Erfindung wird anhand der beigefügten Zeichnungen näher erläutert.The present invention will be explained in more detail with reference to the accompanying drawings.

Fig. 1 zeigt ein Elektrofilter 1, zum Reinigen staubbeladener Abgase A, welche von einer Seite des Elektrofilters 1 zugeführt werden. Üblicherweise befinden sich die Komponenten des Elektrofilters 1 in einem Gehäuse G. Das Elektrofilter 1 besteht aus Reihen von Niederschlagselektroden 2, welche üblicherweise plattenförmig ausgebildet sind. Zwischen den Reihen der Niederschlagselektroden 2 sind Sprühelektroden 3 angeordnet, welche auf einem negativen Hochspannungspotential liegen. Den Niederschlagselektroden 2 und den Sprühelektroden 3 sind entsprechende Klopfeinrichtungen 4, 5 zugeordnet. Die Klopfeinrichtungen für die Niederschlagselektroden und Sprühelektroden beinhalten entsprechende Abklopforgane 6 und 7, welche an entsprechende Ambosse 8 und 9 der Niederschlagselektroden 2 bzw. Sprühelektroden 3 klopfen und ein Abschleudern des anhaftenden Staubbelags bewirken. Fig. 1 shows an electrostatic precipitator 1, for cleaning dust-laden exhaust gases A, which supplied from one side of the electrostatic precipitator 1 become. Usually, the components of the electrostatic precipitator 1 are located in a housing G. The electrostatic precipitator 1 consists of rows of collecting electrodes 2, which are usually plate-shaped. Between the rows of collecting electrodes 2 are arranged spray electrodes 3, which are at a negative high voltage potential. The collecting electrodes 2 and the discharge electrodes 3 are assigned corresponding knocking devices 4, 5. The knocking devices for the collecting electrodes and the discharge electrodes contain corresponding knocking devices 6 and 7, which tap against corresponding anvils 8 and 9 of the collecting electrodes 2 and / or discharge electrodes 3 and cause the adhering dust covering to be thrown off.

Die Ansteuerung der Abklopforgane 6, 7 der Niederschlagselektroden 2 bzw. Sprühelektroden 3 werden durch entsprechende Antriebsvorrichtungen betrieben. Je nach Staubbeladung wird die Abreinigung in unterschiedlichen Zeitintervallen wiederholt. Beim Stand der Technik sind sowohl für die Niederschlagselektroden-Klopfeinrichtung 5 als auch für die Sprühelektroden-Klopfeinrichtung 4 entsprechende Komponenten und Antriebe erforderlich, welche den Aufwand, die Kosten und die Baugröße des Elektrofilters erhöhen.The activation of the knocking members 6, 7 of the collecting electrodes 2 and / or spraying electrodes 3 are operated by corresponding drive devices. Depending on the dust load, the cleaning is repeated at different time intervals. In the prior art, corresponding components and drives are required both for the collecting electrode knocking device 5 and for the spraying electrode knocking device 4, which increase the outlay, the costs and the size of the electrostatic precipitator.

Fig. 2 zeigt eine schematische Ansicht der Inneneinbauten einer erfindungsgemäßen Ausführung eines Elektrofilters 1, wobei die Antriebsvorrichtung der Niederschlagselektroden-Klopfeinrichtung 5 durch einen entsprechenden Antriebsmotor 11, ein Getriebe 12 und eine entsprechende Antriebswelle 13 gebildet ist. An der Antriebswelle 13 ist mindestens ein Abklopforgan 6, insbesondere mindestens ein Purzelhammer gelagert und wird bei Betätigung der Antriebswelle 13 entsprechend gedreht und zum Klopfen an einen Amboss an den Niederschlagselektroden 2 gezwungen, wobei auch mehrere Niederschlagselektroden 2 über eine Verbindungsschiene 18 zusammengefasst und gemeinsam abgereinigt werden können. Erfindungsgemäß wird nun die Antriebsvorrichtung der Niederschlagselektroden-Klopfeinrichtung 5 mit dem Abklopforgan 7 der Sprühelektroden-Klopfeinrichtung 4 gekoppelt, sodass das Abklopforgan 7 über die Antriebswelle 13 der Niederschlagselektroden-Klopfeinrichtung 5 betätigbar ist. Fig. 2 shows a schematic view of the internals of an inventive design of an electrostatic precipitator 1, wherein the drive device of the collecting electrode knocking device 5 by a corresponding drive motor 11, a gear 12 and a corresponding drive shaft 13 is formed. At least one Abklopforgan 6, in particular at least one Purzelhammer is mounted on the drive shaft 13 and is rotated upon actuation of the drive shaft 13 and forced to knock an anvil to the collecting electrodes 2, wherein also several collecting electrodes 2 are combined via a connecting rail 18 and cleaned together can. According to the invention, the drive device of the collecting electrode knocking device 5 is now coupled to the knocking device 7 of the spraying electrode knocking device 4, so that the knocking device 7 can be actuated via the drive shaft 13 of the collecting electrode knocking device 5.

Im Detail gemäß Fig. 3 ist diese Kopplung näher ersichtlich. Demnach wird die Antriebswelle 13 der Antriebsvorrichtung der Niederschlagselektroden-Klopfeinrichtung 5 beim Abreinigen betätigt und das zugehörige Abklopforgan 6 für die Niederschlagselektroden 2 gedreht und auf den zugehörigen Amboss 8 für die Niederschlagselektroden 2 geschleudert. An der Antriebswelle 13 ist ein isolierter Mitnehmer 14 angeordnet, der das Abklopforgan 7 für die Sprühelektroden-Klopfeinrichtung 4 betätigt. Am isolierten Mitnehmer 14 kann eine Rolle 15 angeordnet sein, die am entsprechend ausgestalteten Abklopforgan 7 abrollt. Dadurch wird das Abklopforgan 7 der Sprühelektroden-Klopfeinrichtung 4 betätigt und gegen einen entsprechenden Amboss 9 an einer mehrere Sprühelektroden-Rahmen 19 zusammenfassenden Verbindungsschiene 17 geschleudert.In detail according to Fig. 3 this coupling is more apparent. Accordingly, the drive shaft 13 of the drive device of the collecting electrode knocking device 5 is operated during cleaning and turned the associated Abklopforgan 6 for the collecting electrodes 2 and thrown on the associated anvil 8 for the collecting electrodes 2. On the drive shaft 13, an insulated driver 14 is arranged, which actuates the Abklopforgan 7 for the Sprühelektroden-knocking device 4. At the isolated driver 14, a roller 15 may be arranged, which rolls on the correspondingly designed Abklopforgan 7. As a result, the knock-off element 7 of the spray-electrode knocking device 4 is actuated and thrown against a corresponding anvil 9 on a connecting rail 17 comprising a plurality of spray-electrode frames 19.

Erfindungsgemäß ist also kein eigener Antrieb für die Sprühelektroden-Klopfeinrichtung 4 erforderlich. Das Abklopforgan 7 der Sprühelektroden-Klopfeinrichtung 4 wird über den an der Antriebswelle der Niederschlagselektroden-Klopfeinrichtung 5 angebrachten isolierten Mitnehmer 14 betätigt.According to the invention, therefore, no separate drive for the spray electrode knocking device 4 is required. The knock-off member 7 of the spray-electrode knocking device 4 is actuated by the isolated driver 14 attached to the drive shaft of the knock-down knocking device 5.

Fig. 4 zeigt eine Ausführungsform eines Rahmens 16, mit dem mehrere Sprühelektroden 3 zusammengefasst werden. Der Rahmen 16 ist im unteren Bereich mit einer Einbuchtung 19 versehen, in welcher die entsprechende Antriebsvorrichtung für die Niederschlagselektroden-Klopfeinrichtung 5 angeordnet werden kann. Dadurch resultiert ein Elektrofilter 1, dessen Außenabmessungen kleiner sind als jene von Elektrofiltern mit konventioneller Abreinigung. Fig. 4 shows an embodiment of a frame 16, with which a plurality of discharge electrodes 3 are combined. The frame 16 is provided in the lower region with a recess 19 in which the corresponding drive device for the collecting electrode knocking device 5 can be arranged. This results in an electrostatic filter 1 whose outer dimensions are smaller than those of electrostatic precipitators with conventional cleaning.

Die vorliegende Erfindung ist insbesondere bei kleineren Elektrofiltern für Biomassefeuerungen im Leistungsbereich 0,3-3MW vorteilhaft.The present invention is particularly advantageous for smaller electrostatic precipitators for biomass furnaces in the power range 0.3-3MW.
