Definitions
- the invention relates to a rod-shaped electrode, in particular an electrostatic high-voltage electrode.
- the invention further relates to an electrostatic fine dust filter system comprising said rod-shaped electrode.
- the electrode and the fine dust filter system can be used for the purification of exhaust gases, especially fire bricks.
- Electrostatic dust filters or electrostatic precipitators are systems for the separation of particles from gases, which are based on the electrostatic principle. These systems are used in particular for the electrical cleaning of exhaust gases.
- electrostatic precipitators in the purification of industrial flue gases, for example in the production of electricity from coal, smelting or cement production. There are Monabscheidungsgrade reached up to 99.9%.
- a power plant filter may be a few tens of meters high.
- the separation of particularly toxic fine dust in the range below one micrometer poses a particular challenge to the deposition rate of electrostatic precipitators. Such dusts reach the lungs and therefore can not be coagulated. Depending on the substance, they represent a considerable risk of cancer.
- dust particles are electrically charged by corona discharge and pulled to the oppositely charged electrode.
- the corona discharge takes place on a suitable, charged high voltage electrode inside the exhaust stack.
- the electrode is preferably designed with protruding tips and possibly sharp edges, because there the density of the field lines and thus also the electric field strength is the largest and thus the corona discharge is favored.
- the opposing electrode usually consists of a grounded exhaust pipe section which is mounted around the electrode.
- the degree of separation of an electrostatic filter is particularly dependent on the residence time of the exhaust gases in the filter system and the voltage between the spray and deposition electrode.
- the necessary rectified high voltage is provided by a high voltage generating plant. Protect the high-voltage generator and electrode holder from dust and dirt to prevent unwanted leakage and extend the life of the equipment.

- the hanging high-voltage part passes through an insulator sleeve. Forces acting on the high voltage part are absorbed by elastic seals, some of which bear directly or indirectly on the high voltage part. The freedom of movement of the high voltage part is almost completely prevented by the described structure. Insofar as a movement of the high voltage part is possible, this is severely limited and guided by the applied seals. Vibrations and vibrations can be damped by this structure.
- the support rod optionally with emission electrode, hanging freely suspended in a Insolatorhülse.
- the support bar is in a compliant Material bedded, which fills the space between support rod and insulator. This structure is intended to prevent breakage of the insulator due to vibrations transmitted via the support rod.

Via a horizontal movement of an electrode holding device, a dust precipitate can be shaken loose on electrode parts of the discharge electrodes.
- the publication WO 2008/128353 discloses a damper installation for separating the insulator chamber from the chimney pipe. When the damper installation is closed and the power supply to the electrode frame holding member is turned off, maintenance of the insulator can be performed while the exhaust gas continues to flow through the stack.

- the electrode has one or more bending or bending points, it is possible to mount the electrode laterally via an opening in the exhaust duct and dismantle.
- the opening in the chimney can be sized to the minimum size due to the maximum breakdown distance.
- the design of a chimney does not severely limit the design and design of the filter unit, since a lateral opening is sufficient as an inlet for the electrode. All other filter elements can be mounted on the outside of the fireplace.
- the electrostatic fine dust filter system further includes a flexible insulating holder, a high voltage insulator, the electrode side of the insulator at least one arm with a holding means for holding a holding means preferably vertically hanging high voltage electrode and mounting side of the insulator at least one mounting means for mounting the holder, wherein the holder equipped with at least one restoring element.

- the insulator advantageously has a lamellar structure. This advantageously runs upwards in a fir-shaped manner, preferably tapering towards the electrode side. A continuous layer of dirt can be largely prevented by this design.
- the arm with holding means for holding an electrode protrudes in the direction of taper from the tip of the tapered insulator.
- the insulator is made of silicone, for example, as this material has a strong insulating effect. Silicone itself has a certain elasticity. It is therefore alternatively conceivable that the insulator and mandrel are designed such that the insulator itself acts as a restoring element, can act in part.

- the counter electrode can be grounded.
- the high-voltage electrode 13 is preferably electrically connected via an electrode guide 15, an insulator 17 and a high-voltage cable 19 to an electronic high-voltage generating and control device 23.
- the electrode guide 15 is guided through an opening 25 in the wall of the exhaust passage 9 to the outside.
- the electrode guide 15 is designed with an electrode attachment 27 to which the high-voltage electrode 13 is attached, preferably releasably secured.

- the insulator mandrel 17 carries an insulator 31, which is preferably lamellar and tapered toward the electrode side, the lamellae 33 spaced layers of radial thickening of the base diameter 35 of the insulator 31 represent.
- the insulator mandrel 17 protrudes from the tip of the insulator, in particular in the tapering direction, into the electrode guide 15 and the electrode attachment 27 on the insulator side. Insulator dome 17 and electrode guide 15 form an arm with the electrode attachment 27 for holding an electrode 13.
- the insulator 31 is detachably inserted in an insulator mount 37, which is designed in such a way that in the inserted position, a high-voltage cable 19 establishes an electrical connection between insulator dome 17 and high-voltage generating and control electronics 23.
- the electrical connection between the insulator dome 17 and high voltage cable 19 as well as the high voltage cable itself are carried out against the console 41 and the restoring elements 43 electrically insulating.

- the insulator holder 37 is flexibly mounted on a bracket 41.
- the console 41 is fixed to the chimney 9 by means of a mounting means (not shown) immovably at a mounting location 40.
- Restoring elements 43 provide flexibility, so that a force on electrode 13, electrode guide 15 or insulator mandrel 17 can be absorbed by a change in position and with decreasing force the home position restoring, preferably gurfedemd, can be taken again.
- the restoring elements 43 act simultaneously as joints, kinks and memory for the restoring force.

- the described flexible mounting of the high-voltage insulator 31 and the high-voltage electrode 13 results in the electrode 13 preferably escaping the electrode guide 15, for example a force emanating from a cleaning brush 45. Jamming or hanging of the cleaning brush 45 on the electrode 13 or electrode guide 15, as well as a deformation of the electrode 13 or electrode guide 15 can be prevented with this arrangement.
- the evasive movement 46 of the entire electrode holder 45, preferably the high-voltage filter system 11 due to the action of force during the cleaning movement 47 of a cleaning brush 45 is in FIG. 2 demonstrated. Due to the impact forces during cleaning, the electrode holder 49 is strongly deflected.

- the insulator 31 is tapered towards the top, so it tapers towards the top. This shape allows a minimum size of the particulate filter 11 or 12.
- the dimensions of the insulator 31 as well as the entire filter 11 or 12 are defined by the strike-through distances through the tapered shape (fir tree shape) increases the isolation distance 61 and thus the breakdown distance in the upper region. In the lower region, the voltages are smaller due to the potential gradient, so that the insulation distance 63 can be kept small.

- the insulator 31 is inserted positively and non-positively on an insulator holder 37. There are no screws
- Each ohmic resistance R represents a lamella of the insulator 31.
- An advantageous insulator material is silicone. Silicone has a very high temperature and ozone resistance. Due to its hydrophobic property, it is water and dirt repellent. Creepage currents can thus be reduced to a minimum. The service life of the filter 11 or 12 is thereby maximized. Due to the lamellar shaping, a forming electrically conductive dirt layer will be able to form only with interruptions, thus the lamella structure efficiently prevents a voltage breakdown on the chimney outer skin.
- the insulator dome 17 can be made flexible. This makes it possible that in combination with an elastic insulator material such as silicone, the insulator 31 acts elastically restoring.
- the electrode 13 itself can be made flexible.
- FIG. 5 Two general embodiments of a rod-shaped self-resetting electrostatic high-voltage electrodes 67 and 69 are shown: In a longitudinally segmented embodiment (electrode 67 in FIG. 5a ), flexible self-resetting elements 71 and rigid, rigid members 73 are arranged in alternating order. In a longitudinally one-piece, ie non-segmented, embodiment (electrode 69 in FIG. 5b ), the electrode consists of a single self-resetting resilient element 75. Self-resetting resilient elements 71 and 75 may be embodied, for example, as domed chrome steel spring plates. In FIG.
- 6a is a rod-shaped sheet-metal strip 77 which is curved perpendicular to its longitudinal axis shown.
- An unbombieres long piece of sheet metal is relatively easy to bend in the longitudinal direction. If such a piece of sheet metal is bent transversely to its longitudinal direction, it has a stiffening effect. A bending in its longitudinal axis now requires a greater force than is the case with an unbomb elected sheet metal strip; In addition, the stretched shape of the metal strip resiliently with a higher spring force again.
- FIG. 6b are two convex metal strips 79, which are interconnected at their respective convex sides, so to speak, back to back, via connecting points 81, such as rivets, is shown.
- FIG. 7 Other cross sections of possible shapes and arrangements of cambered sheet metal strips are in FIG. 7 demonstrated.
- Figure 7a the curved shape of a cross section of a single cambered spring strip 83 is shown
- FIG. 7b the arrangement of two metal strips 85 with the respective convex sides pressed against each other is shown in cross section
- FIG. 7c the arrangement of three sheet metal strips 87 is shown with its convex sides pressed against the respective two end regions on each one of the other two metal strips.
- FIG. 7d shows a cross-section of an S-shape curved spring steel strip 89.

- FIG. 7f an arrangement of four metal strips 93 is shown in cross-section, wherein two first metal strips are arranged with the respective convex sides against each other and the two further metal strips are arranged with the convex sides to the concave outer sides of the first two metal strips.
- Sheet metal strips with these cross sections and these arrangements or with similar cross sections and arrangements can be used as electrodes 75 or as electrode sections 71 in conjunction with rigid intermediate elements 73 FIGS. 5a and 5b be used.
- the edges of the metal strips are tapered as far as possible, so that the electrostatic coronal discharge proceeds as homogeneously and reliably.
- FIG. 8 are orientation and curvature of a self-resetting high voltage electrode 67 in the operating position ( FIG. 8a ) and when removing the electrode during, for example, maintenance ( FIG. 8b ). Due to the restoring spring force, the electrode is stretched in the operating position ( FIG. 8a ). The spring force counteracts electrical forces that could cause the electrode 67 to vibrate. Upon removal of the electrode 67 from the exhaust duct 9 this bends due to the applied muscle power of entrusted with the maintenance, installation or cleaning of the plant a person, whereby the removal of the electrode 67 is facilitated.
- electrode holder 48 or 49 and electrodes 13 will be described functionally.
- the exhaust gas rising in the exhaust duct 9 of a chimney with a described filter unit 11 or 12 is field-ionized in the passage in the vicinity of the electrode 13.
- This dust particles are electrostatically charged and deposited on the counter electrode.
- the inner surface of the exhaust duct 9 can serve here for example as a counter electrode.
- the resulting particulate matter precipitation is occasionally removed from the chimney sweep in smaller installations, such as in private wood-burning fireplaces and wood heating systems.
- the cleaning can be done from below or from above. However, the procedure is often country-specific.
- cleaning brushes and brushes 45 may be pushed up by hand. If the electrode 13 itself is flexible or has its holder 48 or 49 flexibly mounted, the electrode 13 and optionally the flexible electrode holder 48 or 49 are pushed by the brush 45 to the side and / or upwards. The electrode 13 thus does not constitute an obstacle to the prescribed cleaning. The cleaning can be done quickly and safely.
- the flexible electrode holder 48 or 49 can be easily pushed aside because of their flexibility and optionally the electrode 13 are removed.
- the electrode guide 15 or 16 pulled out of its holder and through the electrode insertion opening 25 of the Exhaust duct 9 removed.
- a flexible electrode 13 such as electrode 67 or 96 according to FIG. 5
- this step is particularly simple, because the bendable electrode kinks when touched or when deflecting the lot and can be easily pulled out of the narrow opening 25.
- the insulator 31 with mandrel 17 or 18 can be removed. The opening 25 of the exhaust passage 9 is thereby freely accessible.
- Electrode 13 nor electrode holder 48 or 49 thus form an obstacle to the prescribed cleaning.
- the cleaning can be done quickly and safely. Disassembly and reassembly are quick and easy. Since the items to be moved are relatively small and handy, it ensures good stability of the chimney sweep and thus its safety.
- the electrode holder 48 or 49 and the electrode 13 due to their flexibility without disassembly only to the side to push and introduce the cleaning brush from the exhaust gas outlet opening 95 or from the electrode inlet opening 25 ago in the exhaust duct 9.
- the electrode holder is however stiff (eg if the springs 43, 55, 56, 57, 59 are in accordance with FIG FIGS. 1 and 3 are not present), yet the exhaust duct 9 and electrode 13 can be serviced and / or cleaned from the roof.
- the flexible electrode can be removed from the holder and can be brought out of the exhaust gas channel 9 due to its flexibility through the electrode insertion opening 25.
- the resetting spring forces are all designed in such a way that the springs give way slightly under the forces that act during cleaning and maintenance, but that under operating conditions the parts of the plant remain firmly fixed relative to the chimney and have no vibrations.

Description
Die Erfindung betrifft eine stabförmige Elektrode, insbesondere eine elektrostatische Hochspannungselektrode. Die Erfindung betrifft des Weiteren eine elektrostatische Feinstaubfilteranlage beinhaltend die genannte stabförmige Elektrode. Die Elektrode und die Feinstaubfilteranlage können zur Abgasreinigung, insbesoridere von Feueramlagen, verwendet werden.The invention relates to a rod-shaped electrode, in particular an electrostatic high-voltage electrode. The invention further relates to an electrostatic fine dust filter system comprising said rod-shaped electrode. The electrode and the fine dust filter system can be used for the purification of exhaust gases, especially fire bricks.
Elektrostatische Staubfilter oder auch Elektroabscheider genannt sind Anlagen zur Abscheidung von Partikeln aus Gasen, die auf dem elektrostatischen Prinzip beruhen. Diese Anlagen werden insbesondere zur elektrischen Reinigung von Abgasen verwendet.Electrostatic dust filters or electrostatic precipitators are systems for the separation of particles from gases, which are based on the electrostatic principle. These systems are used in particular for the electrical cleaning of exhaust gases.
Ihre hauptsächliche Anwendung finden Elektrofilter in der Reinigung von industriellen Rauchgasen, beispielsweise bei der Stromerzeugung aus Kohle, bei der Verhüttung oder der Zementherstellung. Dort werden Gesamtabscheidungsgrade bis zu 99,9 % erreicht. Ein Kraftwerksfilter ist unter Umständen einige zehn Meter hoch. Die Abscheidung von besonders giftigen Feinstäuben im Bereich unter einem Mikrometer stellt eine besondere Herausforderung an die Abscheidungsrate von Elektrofiltern dar. Solche Stäube gelangen in die Lunge und können daher nicht abgehustet werden. Sie stellen je nach Substanz ein erhebliches Krebsrisiko dar.Their main application are electrostatic precipitators in the purification of industrial flue gases, for example in the production of electricity from coal, smelting or cement production. There are Gesamtabscheidungsgrade reached up to 99.9%. A power plant filter may be a few tens of meters high. The separation of particularly toxic fine dust in the range below one micrometer poses a particular challenge to the deposition rate of electrostatic precipitators. Such dusts reach the lungs and therefore can not be coagulated. Depending on the substance, they represent a considerable risk of cancer.
Feinstaubanteile sind jedoch nicht nur in industriellen Abgasen vorhanden sondern auch in privaten. Um diese Abgase ebenfalls effizient zu reinigen werden heute Elektrofilteranlagen auf Kamine privater oder gewerblicher Feuerungsanlagen aufmontiert. Montage, Wartung und Reinigung von privaten und gewerblichen Feuerungsanlagen und deren Filteranlagen stellen andere Anforderungen als die Grossanlagen der Industrie. Vor allem sind industrielle kontinuierliche Lösungen zur Reinigung von Kaminen sehr teuer und bei privater oder gewerblicher Nutzung einer Feuerungsanlage nicht rentabel; vielmehr wird hier die Reinigung von Kaminfegern, z.B. alljährlich, durchgeführt. Eine Elektrofilteranlage zur Rauchgasreinigung von Kleinfeuerungsanlagen, die mit Holz, Stroh oder anderen regenerativen Brennstoffen oder Kohle befeuert werden ist in der Patentschrift
Bei Elektrofiltern werden Staubteilchen durch Koronaentladung elektrisch aufgeladen und zur entgegengesetzt aufgeladenen Elektrode gezogen. Die Koronaentladung findet auf einer dafür geeigneten, geladenen Hochspannungselektrode im Innern des Abgaskamins statt. Die Elektrode ist bevorzugt mit herausragenden Spitzen und eventuell scharfen Kanten ausgeführt, weil dort die Dichte der Feldlinien und damit auch die elektrische Feldstärke am größten und somit die Koronaentladung begünstigt ist. Die gegengesetzte Elektrode besteht für gewöhnlich aus einem geerdeten Abgasrohrabschnitt, der um die Elektrode gelagert ist. Der Abscheidungsgrad eines Elektrofilters ist insbesondere von der Verweilzeit der Abgase im Filtersystem und der Spannung zwischen Sprüh- und Abscheidungselektrode abhängig. Die dafür notwendige gleichgerichtete Hochspannung wird von einer Hochspannungserzeugungsanlage bereitgestellt. Die Hochspannungserzeugungsanlage und die Halterung für die Elektrode sind vor Staub und Verschmutzung zu schützen, um ungewollte Kriechströme zu vermeiden und die Standzeit der Anlage zu verlängern.In electrostatic precipitators dust particles are electrically charged by corona discharge and pulled to the oppositely charged electrode. The corona discharge takes place on a suitable, charged high voltage electrode inside the exhaust stack. The electrode is preferably designed with protruding tips and possibly sharp edges, because there the density of the field lines and thus also the electric field strength is the largest and thus the corona discharge is favored. The opposing electrode usually consists of a grounded exhaust pipe section which is mounted around the electrode. The degree of separation of an electrostatic filter is particularly dependent on the residence time of the exhaust gases in the filter system and the voltage between the spray and deposition electrode. The necessary rectified high voltage is provided by a high voltage generating plant. Protect the high-voltage generator and electrode holder from dust and dirt to prevent unwanted leakage and extend the life of the equipment.

Der oben genannte Stand der Technik gibt keine Hinweise zur konstruktiven Ausführung von Halterungen für elektrostatische Hochspannungselektroden von vorwiegend Kleirefeueranlagen, welche üblicherweise vom Kaminfeger mit Bürste gereinigt werden.The above-mentioned prior art gives no indications for constructive execution of holders for electrostatic high voltage electrodes of mainly Kleirefeueranlagen, which are usually cleaned by a chimney sweep with brush.
Es ist die Aufgabe der vorliegenden Erfindung eine elektrostatische Feinstaubfilteranlage, insbesondere Elektrode und Elektrodenhalterung, derart auszuführen, dass Montage, Wartung und Reinigung von Feinstaubfilter und Kamin, zum Beispiel von Hauskaminen mit Holzfeuerung, leicht durchführbar sind. Insbesondere soll die Reinigung sowohl vom Dach aus wie auch von unten, d.h. vom Ofen her leicht durchführbar sein. Zusätzlich soll die die Sicherheit von Kaminfeger und Monteur bei Ausführung der Montage-, Service-, Wartungs- und Reinigungsarbeiten gewährt werden.It is the object of the present invention to carry out an electrostatic fine dust filter system, in particular electrode and electrode holder, in such a way that assembly, maintenance and cleaning of fine dust filter and chimney, for example of house fireplaces with wood firing, are easy to carry out. In particular, the cleaning of both the roof as well as from below, ie be easily feasible from the oven. In addition, the safety of chimney sweep and fitter should be granted in performing the assembly, service, maintenance and cleaning work.
Erfindungsgemäss wird die Aufgabe mit einer stabförmigen Elektrode gemäss Anspruchs 1 und einer Feinstaubfilteranlage gemäss Anspruch 12 dadurch gelöst, dass die Elektrode beweglich und selbstrückstellend, insbesondere federnd ausgeführt ist. Gemäss einer besonderen Ausführungsform wird die Aufgabe mit der Verwendung bombierter flexibler Teile zur Herstellung der Elektrode gelöst.According to the invention the object is achieved with a rod-shaped electrode according to claim 1 and a fine dust filter system according to
Die erfindungsgemässe stabförmige Elektrode, insbesondere die elektrostatische Hochspannungselektrode, zeichnet sich dadurch aus, dass die Elektrode zumindest ein Federelement mit rückstellender Kraft enthält, wobei das Federelement unter äusserer Krafteinwirkung eine Biegung und/oder Knickung der Elektrode ermöglicht und bei fehlender äusserer Krafteinwirkung die Elektrode in die Betriebsposition rückstellt. Die stabförmige Elektrode, insbesondere die elektrostatische Hochspannungselektrode, besteht aus einem Federelement mit rückstellender, d.h. elastischer, Federkraft oder beinhaltet zumindest ein Federelement mit rückstellender, d.h. elastischer, Federkraft, das unter Krafteinwirkung eine Bewegung, insbesondere eine Biegung, Knickung oder Deformation, der Elektrode ermöglicht und bei fehlender Krafteinwirkung die Elektrode in die Grundposition, z.B. in eine gestreckte Position, zurückspringen lässt. Die Biegung und die Rückstellung sind elastisch. Die Elektrode weist sich also durch eine einerseits steife und andererseits elastisch selbstrückstellende Bauform aus. Dadurch dass die Elektrode eine oder mehrere Biege- oder Knickstellen aufweist, ist es möglich die Elektrode seitlich über eine Öffnung im Abgaskanal zu montieren und demontieren. Bei einer Reinigung von unten her, kann die Elektrode mit dem Reinigungsbesen weggedrückt werden. Hierdurch wird die Arbeit des Kaminfegers vereinfacht; insbesondere ist die Reinigung vom Dach her nicht mehr nötig. Während des Betriebs weist die Elektrode hohe Steifigkeit und gleichzeitig gute Dämpfwirkung auf. Die Federkraft kann hierbei so eingestellt und dimensioniert werde, dass die Kräfte des Abgasstroms, d.h. der dadurch erzeugte Luftwiederstand an der Elektrode, und die elektrostatischen Kräfte, die auf die Elektrode wirken, kein Aufschwingen der Elektrode verursachen. Die Elektrode kann mit einem zusätzlichen Gewicht im Lot gehalten werden. Das zumindest eine Federelement der Elektrode kann als Feder, z.B. Stahlfeder, ausgebildet sein. Das zumindest eine Federelemente ist aufgrund seiner Konstruktion und/oder seiner Materialeigenschaften selbstrückstellend.The rod-shaped electrode according to the invention, in particular the electrostatic high-voltage electrode, is characterized in that the electrode contains at least one spring element with restoring force, wherein the spring element allows a bending and / or buckling of the electrode under external force action and in the absence of an external force effect the electrode Resets operating position. The rod-shaped electrode, in particular the electrostatic high-voltage electrode, consists of a spring element with restoring, ie elastic, spring force or includes at least one spring element with restoring, ie elastic, spring force, which under force a movement, in particular a bend, buckling or deformation, allows the electrode and if no force is applied, the electrode can spring back into the basic position, eg into an extended position. The bend and the return are elastic. Thus, the electrode is characterized by an on the one hand rigid and on the other hand elastically self-resetting design. The fact that the electrode has one or more bending or bending points, it is possible to mount the electrode laterally via an opening in the exhaust duct and disassemble. When cleaning from below, the electrode can be pushed away with the cleaning brush. As a result, the work of Kaminfegers is simplified; In particular, cleaning from the roof is no longer necessary. During operation, the electrode has high rigidity and at the same time good damping effect. The spring force can in this case be set and dimensioned so that the forces of the exhaust gas flow, ie the air resistance generated thereby at the electrode, and the electrostatic forces acting on the electrode, cause no swinging of the electrode. The electrode can be held in place with an additional weight. The at least one spring element of the electrode can be used as a spring, eg steel spring, be educated. The at least one spring elements is self-resetting due to its construction and / or its material properties.
Vorteilhafterweise besteht das Federelement aus mindestens einem bombierten Federblechstück, das quer zur Elektrodenlängsrichtung bombiert ist. Die Krümmung des Elektrodenquerschnitts (d.h. die Krümmung in Elektrodenquerrichtung einer stabförmigen Elektrode), die durch Bombieren eingebracht wird, hat vorteilhafterweise einen Radius von 5 bis 100 mm (Millimeter), bevorzugt von 10 bis 40 mm und weiter bevorzugt von 18 bis 22 mm. Zweckmässigerweise besitzt die Elektrode in ihrem Querschnitt eine Bogenlänge von 8 bis 100 mm, bevorzugt von 12 bis 50 mm und meist bevorzugt von 16 bis 25 mm. Vorteilhafterweise ist die Elektrode 1 bis 4 m (Meter) lang. Zweckmässigerweise wird für ein Abgasrohr mit eher grossem Durchmesser eine eher lange Elektrode verwendet. Ein bombiertes Federstahlblech weist eine sehr hohe Steifigkeit auf und lässt sich dennoch leicht Knicken. Sobald keine äussere Kraft mehr auf das Federstahlblech einwirkt, springt es wider in den gestreckten Zustand zurück. Zudem ist der Knickpunkt über die Länge des Blechs frei verschiebbar.Advantageously, the spring element consists of at least one cambered Federblechstück which is cambered transversely to the electrode longitudinal direction. The curvature of the electrode cross-section (that is, the curvature in the electrode transverse direction of a rod-shaped electrode) introduced by crowning advantageously has a radius of 5 to 100 mm (millimeters), preferably 10 to 40 mm, and more preferably 18 to 22 mm. Conveniently, the electrode in its cross section has an arc length of 8 to 100 mm, preferably from 12 to 50 mm and most preferably from 16 to 25 mm. Advantageously, the electrode is 1 to 4 meters (meters) long. Conveniently, a rather long electrode is used for an exhaust pipe with a rather large diameter. A cambered spring steel sheet has a very high rigidity and can still be easily bent. As soon as no external force acts on the spring steel sheet, it springs back into the stretched state. In addition, the break point over the length of the sheet is freely movable.
Im Weiteren kann das Federelement aus zumindest zwei oder mehr bombierten Federblechstücken bestehen, welche mit konvexen Seitenbereichen oder mit konvexen und konkaven Seitenbereichen gegeneinander angeordnet verbunden sind. Dies komplexere Bauform resultiert in einer stärkeren Federkraft der Elektrode.Furthermore, the spring element may consist of at least two or more cambered Federblechstücken, which are connected to each other with convex side portions or with convex and concave side portions. This more complex design results in a stronger spring force of the electrode.
In einer Ausführungsform umfasst die stabförmige elektrostatische Hochspannungselektrode Federelemente, welche sich im Wesentlichen über die ganze Länge der Elektrode erstrecken.In one embodiment, the rod-shaped electrostatic high-voltage electrode includes spring elements that extend substantially the entire length of the electrode.
In einer Ausführungsform enthält die stabförmige elektrostatische Hochspannungselektrode Federelemente und formstabile Elemente in wechselnder Abfolge, insbesondere in wechselnder Abfolge in der Längsrichtung der Elektrode. Bei Verbiegung können sich hierbei mehrere Knickpunkte gleichzeitig einstellen.In one embodiment, the rod-shaped electrostatic high-voltage electrode contains spring elements and dimensionally stable elements in alternating sequence, in particular in alternating sequence in the longitudinal direction of the electrode. In case of bending several bending points can occur simultaneously.
Vorteilhafterweise ist die rückstellende Federkraft der Federelemente derart bemessen, dass die Federelemente durch Muskelkraft, insbesondere durch Einsatz von Armen und Händen, einer mit der Wartung, Montage oder Reinigung der Anlage betrauten Person, gebogen oder geknickt werden können.Advantageously, the restoring spring force of the spring elements is dimensioned such that the spring elements can be bent or kinked by muscular force, in particular by using arms and hands, a person entrusted with the maintenance, installation or cleaning of the system.
Zweckmässigerweise ist die rückstellende Federkraft des oder der Federelemente derart ausgelegt, dass das Federelement bezugsweise die Federelemente zumindest um 10 Grad, bevorzugt zumindest um 20 Grad, weiter bevorzugt zumindest um 45 Grad und weiter bevorzugt zumindest um 90 Grad geknickt werden können, bezugsweise gebogen werden können. Im Weiteren ist es von Vorteil, wenn die einzelnen Federelemente um zumindest 10 und bis zu 180 Grad, vorteilhafterweise um zumindest 20 und bis zu 170 Grad knickbar bezugsweise biegbar sind. Zu beachten ist, dass aus je weniger Federelemente die Elektrode aufgebaut ist, desto stärker sollten sich die Elemente knicken lassen. Die zur Beugung nötige Kraft hängt hierbei vom Material und den Stababmessungen ab.Conveniently, the restoring spring force of the spring or the spring elements is designed such that the spring element preferably the spring elements at least may be bent by 10 degrees, preferably at least 20 degrees, more preferably at least 45 degrees and more preferably at least 90 degrees. Furthermore, it is advantageous if the individual spring elements are bendable by at least 10 and up to 180 degrees, advantageously by at least 20 and up to 170 degrees bendable. It should be noted that the fewer the spring elements the electrode is constructed of, the more the elements should bend. The force required for diffraction depends on the material and the rod dimensions.
Zweckmässigerweise besitzt eine Elektrode scharfe Kanten oder Spitzen zur Ionisation. Die Kanten oder Spitzen haben dabei bevorzugt einen Radius von weniger als 1 mm, weiter bevorzugt weniger als 0.5 mm und weiter bevorzugt weniger als 0.2 mm.Conveniently, an electrode has sharp edges or tips for ionization. The edges or tips preferably have a radius of less than 1 mm, more preferably less than 0.5 mm and more preferably less than 0.2 mm.
Bei einer weiteren vorteilhaften erfindungsgemässen Ausführung einer stabförmigen Elektrode, insbesondere einer elektrostatischen Hochspannungselektrode, bestehen die Elektroden zumindest teilweise aus bombiertem Blech, insbesondere Federstahlblech.In a further advantageous embodiment of a rod-shaped electrode according to the invention, in particular an electrostatic high-voltage electrode, the electrodes consist at least partially of cambered sheet metal, in particular spring steel sheet.
Vorteilhaft bestehen die Elektroden (insbesondere die Elektrodenoberfläche) zu mindestens 20 Prozent, bevorzugt zu mindestens 50 Prozent, weiter bevorzug zu mindestens 80 Prozent und weiter bevorzugt im Wesentlichen aus bombiertem Federstahlblech.Advantageously, the electrodes (in particular the electrode surface) consist of at least 20 percent, preferably at least 50 percent, more preferably at least 80 percent and more preferably substantially from cambered spring steel sheet.
Erfindungsgemäss werden bombierte Federstähle zur Herstellung von stabförmagen Elektroden, insbesondere elektrostatischen Hochspannungselektroden, verwendet Durch ihre selbstrückstellenden Federkräfte sind diese Elektroden und die Anlagen in den die Elektroden verwendet werden, leicht zu montieren, zu warten und zu reinigen.In accordance with the invention, cambered spring steels are used to produce rod-shaped electrodes, in particular electrostatic high-voltage electrodes. Due to their self-resetting spring forces, these electrodes and the equipment in which the electrodes are used are easy to assemble, maintain and clean.
Erfindungsgemäss kann bombierter Federstahl zur Herstellung von Elektroden, insbesondere elektrostatischen Hochspannungselektroden verwendet werden.Cambered spring steel according to the invention can be used for producing electrodes, in particular electrostatic high-voltage electrodes.

Die erfindungsgemässe elektrostatische Feinstaubfilteranlage zeichnet sich vorzugsweise dadurch aus, dass die Anlage weiter eine Halterung für die elektrostatische Hochspannungselektrode beinhaltet.The inventive electrostatic fine dust filter system is preferably characterized in that the system further includes a holder for the electrostatic high-voltage electrode.
Die Aufgabe ist insbesondere gelöst durch eine erfindungsgemässe elektrostatische Feinstaubfilteranlage beinhaltend eine elektrostatische Hochspannungselektrode und gegebenenfalls eine Gegenelektrode, wobei die Anlage weiter eine Halterung für die Hochspannungselektrode beinhaltet, welche insbesondere zumindest aus einem Hochspannungsisolator, elektrodenseitig des Isolators einem Arm mit einem Haltemittel zum Halten einer am Haltemittel bevorzugt vertikal hängenden Hochspannungselektrode und montageseitig des Isolators einem Montagemittel zur Montage der Halterung besteht, und wobei die Halterung im Weiteren mit wenigstens einem rückstellenden Element mit selbstrückstellender Federkraft ausgestattet ist. Das rückstellende Element bildet hierbei eine gelenkige Verbindung zwischen dem zumindest einen Montagemittel und dem Haltemittel und ermöglicht bei der Reinigung im Abgaskanal mit einem Reinigungsgerät ein Ausweichen des Haltemittels und gegebenenfalls einer daran angebrachten Hochspannungselektrode aus der Betriebsposition und ein selbsttätiges Rückstellen in die Betriebsposition. Das rückstellende Element wirkt selbstrückstellend sobald eine äussere Kraft die Position der Halterung verändert. Dies hat den Vorteil, dass zum Beispiel bei der Reinigung mit einer Kaminbürste die Elektrode im Innern des Abgaskanals aufgrund der flexiblen Halterung auf die Seite gedrückt werden kann und dadurch für die Reinigungsbürste kein Hindernis mehr bildet.The object is in particular solved by an inventive electrostatic fine dust filter system comprising an electrostatic high voltage electrode and optionally a counter electrode, wherein the system further includes a holder for the high voltage electrode, which in particular at least from a high voltage insulator, the electrode side of the insulator an arm with a holding means for holding a holding means Preferably, vertically suspended high voltage electrode and the mounting side of the insulator consists of a mounting means for mounting the holder, and wherein the holder is further equipped with at least one restoring element with self-resetting spring force. The restoring element in this case forms an articulated connection between the at least one mounting means and the holding means and allows for cleaning in the exhaust duct with a cleaning device, a deflection of the holding means and optionally attached thereto high-voltage electrode from the operating position and an automatic return to the operating position. The restoring element acts self-restoring as soon as an external force changes the position of the holder. This has the advantage that, for example, when cleaning with a chimney brush, the electrode inside the exhaust duct can be pressed on the side due to the flexible support and thus no longer forms an obstacle to the cleaning brush.
Vorteilshafterweise ist hierbei die Hochspannungselektrode als stabförmige Elektrode ausgebildet, die zumindest ein rückstellendes Element mit rückstellender Federkraft enthält, das unter Krafteinwirkung eine Knickung der Elektrode ermöglicht und bei fehlender Krafteinwirkung die Elektrode versteift.Advantageously, in this case the high-voltage electrode is formed as a rod-shaped electrode which contains at least one resetting element with restoring spring force, which allows a buckling of the electrode under the action of force and stiffens the electrode in the absence of force.
Die erfindungsgemässe elektrostatische Feinstaubfilteranlage beinhaltet eine elektrostatische Hochspannungselektrode und gegebenenfalls eine Gegenelektrode und zeichnet sich dadurch aus, dass die Hochspannungselektrode als stabförmige elektrostatische Hochspannungselektrode wie hierin beschrieben ausgebildet ist.The electrostatic fine dust filter system according to the invention comprises an electrostatic high-voltage electrode and optionally a counterelectrode and is characterized in that the high-voltage electrode is designed as a rod-shaped electrostatic high-voltage electrode as described herein.
Die erfindungsgemässe elektrostatische Feinstaubfilteranlage beinhaltet eine elektrostatische Hochspannungselektrode und gegebenenfalls eine Gegenelektrode, wobei die Hochspannungselektrode als stabförmige elektrostatische Hochspannungselektrode ausgebildet ist, die insbesondere zumindest ein rückstellendes Element mit rückstellender Federkraft enthält, das unter Krafteinwirkung eine Knickung der Elektrode ermöglicht und bei fehlender Krafteinwirkung die Elektrode versteift. Dadurch dass die Elektrode eine oder mehrere Biege- oder Knickstellen aufweist, ist es möglich die Elektrode seitlich über eine Öffnung im Abgaskanal zu montieren und zu demontieren. Die Öffnung im Kamin kann auf die minimale Grösse aufgrund der maximalen Durchschlagsstrecke bemessen werden. Das Design eines Kamins bildet keine starke Einschränkung hinsichtlich Konzeption und Design der Filteranlage, da eine seitliche Öffnung als Einlass für die Elektrode genügt. Alle weiteren Filterelemente können aussen am Kamin montiert werden.The electrostatic fine dust filter system according to the invention comprises an electrostatic high-voltage electrode and optionally a counterelectrode, wherein the high-voltage electrode is formed as a rod-shaped electrostatic high-voltage electrode which contains in particular at least one resetting element with resetting spring force, which allows a buckling of the electrode under the action of force and stiffens the electrode in the absence of force. The fact that the electrode has one or more bending or bending points, it is possible to mount the electrode laterally via an opening in the exhaust duct and dismantle. The opening in the chimney can be sized to the minimum size due to the maximum breakdown distance. The design of a chimney does not severely limit the design and design of the filter unit, since a lateral opening is sufficient as an inlet for the electrode. All other filter elements can be mounted on the outside of the fireplace.
Vorteilhafterweise beinhaltet hierbei die elektrostatischer Feinstaubfilteranlage weiter eine flexible isolierende Halterung, die einen Hochspannungsisolator, elektrodenseitig des Isolators zumindest einen Arm mit einem Haltemittel zum Halten einer am Haltemittel bevorzugt vertikal hängenden Hochspannungselektrode und montageseitig des Isolators zumindest ein Montagemittel zur Montage der Halterung, wobei die Halterung mit wenigstens einem rückstellenden Element ausgestattet ist. Das rückstellende Element bildet hierbei eine gelenkige Verbindung zwischen dem zumindest einen Montagemittel und dem Haltemittel und ermöglicht bei der Reinigung im Abgaskanal mit einem Reinigungsgerät ein Ausweichen des Haltemittels und gegebenenfalls einer daran angebrachten Hochspannungselektrode aus der Betriebsposition und ein selbsttätiges Rückstellen in die Betriebsposition. In einer bevorzugten Ausführungsform ist die Halterung mit wenigstens einem rückstellenden Element mit selbstrückstellender Federkraft ausgestattet.Advantageously, in this case, the electrostatic fine dust filter system further includes a flexible insulating holder, a high voltage insulator, the electrode side of the insulator at least one arm with a holding means for holding a holding means preferably vertically hanging high voltage electrode and mounting side of the insulator at least one mounting means for mounting the holder, wherein the holder equipped with at least one restoring element. The restoring element in this case forms an articulated connection between the at least one mounting means and the holding means and allows for cleaning in the exhaust duct with a cleaning device, a deflection of the holding means and optionally attached thereto high-voltage electrode from the operating position and an automatic return to the operating position. In a preferred embodiment, the holder is equipped with at least one restoring element with self-resetting spring force.
Die Halterung für eine elektrostatische Hochspannungselektrode zur Abgasreinigung beinhaltet erfindungsgemäss einen Hochspannungsisolator, elektrodenseitig des Isolators zumindest einen Arm (bevorzugt nur einen Arm) beinhaltend ein Haltemittel zum Halten einer am Haltemittel bevorzugt vertikal hängenden Hochspannungselektrode und montageseitig des Isolators zumindest ein Montagemittel zur Montage der Halterung an einer Montagestelle ausserhalb eines Abgaskanals eines Kamins, wobei die Halterung mit wenigstens einem Rückstellelement mit rückstellender Eigenschaft ausgestattet ist, welches eine gelenkige Verbindung zwischen dem zumindest einen Montagemittel und dem Haltemittel bildet und welches bei der Reinigung im Abgaskanal mit einem Reinigungsgerät ein Ausweichen des Haltemittels und gegebenenfalls einer daran angebrachten Hochspannungselektrode aus der Betriebsposition und ein selbsttätiges Rückstellen in die Betriebsposition ermöglicht. Das Rückstellelement ist also zwischen dem zumindest einen Montagemittel und dem Haltemittel derart eingebaut, dass das Haltemittel mit dem zumindest einen Montagemittel über das Rückstellelement verbunden ist und dass das Haltemittel gegenüber dem zumindest einen Montagemittel selbstrückstellend, insbesondere elastischen und/oder federnd, beweglich ist. Das wenigstens eine Rückstellelement wirkt rückstellend sobald eine äussere Kraft, welche die Position der Halterung verändert, wegfällt. Als rückstellende Kräfte können Schwerkraft und/oder Federkräfte wirken. Auslenkung aus der Ausgangsposition und Rückstellung sind beliebig wiederholbar. Von Vorteil ist, dass zum Beispiel bei der Reinigung mit einer Kaminbürste die Elektrode im Innern des Abgaskanals aufgrund der flexibel ausgeführten Halterung auf die Seite gedrückt werden kann und dadurch für die Reinigungsbürste kein Hindernis mehr bildet. Das zumindest eine rückstellende Element ist ein bewegliches Element, das als Feder, z.B. Stahlfeder, als Scharnier, mechanisches Gelenk, aus elastischem Material oder aus einer Kombination davon ausgebildet sein kann.The holder for an electrostatic high-voltage electrode for exhaust gas purification according to the invention includes a high voltage insulator, the electrode side of the insulator at least one arm (preferably only one arm) containing a holding means for holding a holding means preferably vertically hanging high voltage electrode and mounting side of the insulator at least one mounting means for mounting the holder to a Mounting location outside an exhaust duct of a chimney, wherein the holder with at least one return element with resetting Feature is provided which forms an articulated connection between the at least one mounting means and the holding means and which allows for cleaning in the exhaust duct with a cleaning device dodging of the holding means and optionally attached thereto high-voltage electrode from the operating position and an automatic return to the operating position. The restoring element is thus installed between the at least one mounting means and the holding means such that the holding means is connected to the at least one mounting means via the return element and that the holding means against the at least one mounting means is self-resetting, in particular elastic and / or resilient, movable. The at least one return element has a restoring effect as soon as an external force which changes the position of the holder is eliminated. As restoring forces gravity and / or spring forces can act. Deflection from the starting position and return can be repeated as required. The advantage is that, for example, when cleaning with a chimney brush, the electrode inside the exhaust duct can be pressed on the side due to the flexible holder and thus no longer forms an obstacle to the cleaning brush. The at least one restoring element is a movable element that can be designed as a spring, eg steel spring, as a hinge, mechanical joint, made of elastic material or a combination thereof.
Insbesondere bei Ausführungsformen, bei denen die Halterung mit wenigstens einem Rückstellelement mit selbstrückstellender Federkraft ausgestattet ist (z.B. bei einer Feder als Rückstellelement oder bei einer Halterungsteilausführung mit elastischem Material, wie etwa Silikon), wirkt das federnde Rückstellelement selbstrückstellend, sobald eine äussere Kraft, welche die Position der Halterung verändert, wegfällt. Die Auslenkung aus der Ausgangsposition und die Rückstellung sind hierbei vorteilhaft elastisch. Bei einer weiteren Ausführungsformen, bei der die Halterung mit wenigstens einem Scharnier als Rückstellelement ausgestattet ist, kann das Rückstelleleinent zum Beispiel aufgrund der Schwerkraft rückstellend wirken, sobald eine äussere Kraft, welche die Grundposition der Halterung verändert hat, wegfällt.In particular, in embodiments in which the holder is equipped with at least one return element with self-resetting spring force (eg in a spring as restoring element or a Haltersteilausführung with elastic material, such as silicone), the resilient return element acts self-restoring, as soon as an external force, which Position of the bracket changed, eliminated. The deflection from the starting position and the provision are advantageously elastic. In a further embodiment in which the holder is provided with at least one hinge as a restoring element, the restoring element may, for example, be restoring due to gravity as soon as an external force which has changed the basic position of the holder is eliminated.
Zweckmässigerweise ermöglicht das wenigstens eine Rückstellelement eine Auslenkung der Halterung oder von Teilen der Halterung aufgrund einer äusseren Kraft und bei Wegfall der äusserer Krafteinwirkung die Rückstellung der Halterung oder der Teile der Halterung in die Betriebsposition (i.e. Grundposition).Conveniently, the at least one return element allows a deflection of the holder or parts of the holder due to an external Force and the loss of external force, the provision of the holder or parts of the holder in the operating position (ie, home position).
Vorteilhafterweise ist das wenigstens eine Rückstellelement derart ausgelegt, dass die Halterung, d.h. der Teile der Halterung, welcher elektrodenseitig vom Rückstellelement angeordnet ist (i.e. insbesondere das Haltemittel), aufgrund einer Biegung oder Drehung des Rückstellelements (insbesondere um den Dreh- oder Biegepunkt des Rückstellelements) um mehr als 5 Grad, bevorzugt um mehr als 10 Grad und weiter bevorzugt um mehr als 20 Grad aus der Grundposition ausgelenkt werden kann. Umso besser die Auslenkbarkeit ist desto besser ist der Zugang bei Reinigung und Wartung der Filteranlage und des Abgaskanals, bzw. des Kamins.Advantageously, the at least one return element is designed such that the holder, i. the parts of the holder which is arranged on the electrode side of the restoring element (ie the holding means), due to a bending or rotation of the return element (in particular about the turning or bending point of the return element) by more than 5 degrees, preferably by more than 10 degrees and on preferably can be deflected by more than 20 degrees from the basic position. The better the deflectability, the better the access for cleaning and maintenance of the filter system and the exhaust duct, or the chimney.
Alternativ ist das wenigstens eine Rückstellelement beim Ausweichen derart auslenkbar, dass das Haltemittel aufgrund einer Biegung und/oder Drehung des Rückstellelements eine Auslenkung bezüglich der Betriebsposition in zumindest horizontaler Richtung um mindestens 5 cm, bevorzugt um mindestens 10 cm, weiter bevorzugt um mindestens 15 cm, weiter bevorzugt um mindestens 20 cm, aus seiner Betriebsposition erfahren kann. Ein Ausweichen oder Auslenken in vertikaler Verschiebung kann zusätzlich erfolgen.Alternatively, the at least one return element can be deflected in such a way that the holding means deflects with respect to the operating position in at least horizontal direction by at least 5 cm, preferably by at least 10 cm, more preferably by at least 15 cm due to a bending and / or rotation of the return element, more preferably at least 20 cm, can learn from its operating position. Dodging or deflection in vertical displacement can also be done.
Vorteilhafterweise ist das zumindest eine Montagemittel mit wenigstens einem Rückstellelement zur Stützung des Isolators ausgestattet. Bevorzugt ist hierbei zwischen dem zumindest einen Montagemittel und dem Isolator zumindest ein Trägermittel, welches das wenigstens eine Rückstellelement trägt, angeordnet. Alternative ist der zumindest eine Arm mit dem wenigstens einen Rückstellelement ausgestattet oder der Isolator ist selbstrückstellend, insbesondere aus elastischem Material, wie zum Beispiel Silikon, ausgeführt. Das rückstellende Element wirkt rückstellend sobald eine äussere Kraft, welche die Position der Halterung verändert, wegfällt. Durch die montageseitige Positionierung des rückstellenden Elements wird ein möglichst grosse Verschiebbarkeit, d.h. Verschiebungsstrecke der Elektrode gewährleistet. Dies ist zum Beispiel bei der Reinigung mit einer Kaminbürste von besonderem Vorteil, da die Elektrode im Innern des Abgaskanals aufgrund der stark flexiblen Halterung bis zur Abgaskanalwand weggedrückt werden kann und dadurch für die Reinigungsbürste kein Hindernis mehr bildet.Advantageously, the at least one mounting means is equipped with at least one return element for supporting the insulator. In this case, at least one carrier means which carries the at least one restoring element is preferably arranged between the at least one mounting means and the insulator. Alternatively, the at least one arm is equipped with the at least one restoring element or the insulator is self-restoring, in particular made of elastic material, such as silicone. The restoring element acts resetting as soon as an external force, which changes the position of the holder, is eliminated. The assembly-side positioning of the restoring element ensures the greatest possible displaceability, ie displacement distance of the electrode. This is for example when cleaning with a chimney brush of particular advantage, since the electrode can be pushed away inside the exhaust duct due to the highly flexible support to the exhaust duct wall and thus no longer forms an obstacle to the cleaning brush.
Vorteilhafterweise ist der Isolator über eine lösbare Verbindung, insbesondere eine Steckverbindung, mit dem zumindest einen Montagemittel, gegebenenfalls über zumindest ein Trägermittel, verbunden. Der Isolator wird bei der Montage nur aufgesteckt und kann zur Wartung jederzeit abgenommen werden. Zudem werden hierzu keine Werkzeuge benötigt.Advantageously, the insulator is connected via a detachable connection, in particular a plug connection, to the at least one mounting means, optionally via at least one carrier means. The insulator is only attached during assembly and can be removed at any time for maintenance. In addition, no tools are needed for this purpose.
Der Isolator sitzt vorteilhafterweise in einer Isolatorhalterung, welche zudem mittels des wenigstens einen rückstellenden Elements am zumindest einen Montagemittel, gegebenenfalls über zumindest ein Trägermittel, auslenkbar verankert ist.The insulator is advantageously seated in an insulator holder, which is also anchored by means of the at least one restoring element on at least one mounting means, optionally via at least one carrier means, deflectable.
Zweckmässigerweise sind drei, vier oder mehr rückstellende Elemente so angeordnet, dass eine rückstellende Dreipunk-, Vierpunkt-, bezugsweise Mehrpunkstützung des Isolators besteht. Die rückstellenden Elemente sind zum Beispiel derart angeordnet, dass eine Art Federtisch entsteht, der zwischen Isolator, bezugsweise Isolatorhalterung und einer zur Montage ausgebildeten Konsole positioniert ist. Das oder die rückstellenden Elemente bilden dabei die Stützbeine des Tisches. Durch eine breite Abstützung, die bei der Verwendung von zum Beispiel vier rückstellenden Elementen gegeben ist, kann das Drehmoment, das aufgrund des Gewichts der Elektrode, gegebenenfalls (ggf.) einer Elektrodenführung, und der darauf wirkenden Kräfte entsteht, besser aufgefangen werden. Im Gegensatz zu einer Federstützung durch nur ein rückstellendes Element ist die Stützung durch mehrere rückstellende Elemente stabiler und trotzdem einfach einstellbar bezugsweise dimensionierbar. Hingegen kann eine Federstützung mit nur einem Rückstellelement unter Umständen konstruktiv einfacher zu realisieren sein und gewährt dabei eine gute Flexibilität und Beweglichkeit der Halterung.Conveniently, three, four or more restoring elements are arranged so that there is a restoring three-point, four-point, preferably Mehrpunkstützung of the insulator. The restoring elements are arranged, for example, such that a kind of spring table is formed which is positioned between the insulator, preferably insulator holder and a bracket designed for mounting. The one or more restoring elements thereby form the support legs of the table. By a broad support, which is given when using, for example, four restoring elements, the torque, due to the weight of the electrode, possibly (possibly) an electrode guide, and the forces acting thereon, can be better absorbed. In contrast to a spring support by only one restoring element, the support by several restoring elements is more stable and yet easily adjustable preferably dimensioned. On the other hand, a spring support with only one restoring element may possibly be structurally simpler to implement and thereby provides good flexibility and mobility of the holder.
Zusätzlich oder alternative können rückstellende Elemente am Isolatordorn an der Elektrodenführung und/oder der Elektrode selbst platziert werden. Zusätzliche rückstellende Elemente können ebenfalls als Federn, z.B. Stahlfeder, als Scharniere oder mechanisches Gelenke ausgebildet sein.Additionally or alternatively, restoring elements may be placed on the insulator mandrel on the electrode guide and / or the electrode itself. Additional restoring elements may also be used as springs, e.g. Steel spring, be designed as hinges or mechanical joints.
Der Isolator weist vorteilhafterweise eine Lamellenstruktur auf. Diese läuft vorteilhafterweise gegen oben tannenförmig zu, bezugsweise verjüngt sich zur Elektrodenseite hin. Eine durchgehende Schmutzschicht kann durch diese Formgebung weitestgehend verhindert werden. Der Arm mit Haltemittel zum Halten einer Elektrode ragt in Zuspitzrichtung aus der Spitze des sich verjüngenden Isolators.The insulator advantageously has a lamellar structure. This advantageously runs upwards in a fir-shaped manner, preferably tapering towards the electrode side. A continuous layer of dirt can be largely prevented by this design. The arm with holding means for holding an electrode protrudes in the direction of taper from the tip of the tapered insulator.
Der Isolator besteht zum Beispiel aus Silikon, da dieses Material stark isolierend wirkt. Silikon selbst besitzt eine gewisse Elastizität. Es ist deshalb alternativ denkbar, dass Isolator und Dorn derart ausgeführt werden, dass der Isolator selbst als rückstellendes Element wirkt, bezugsweise wirken kann. Silikon ist zudem stark wasser- und schmutzabweisend. Kriechströme können somit auf ein Minimum reduziert und die Standzeit der Anlage maximiert werden. Im Weiteren hat Silikon eine hohe Temperatur- und Ozonbeständigkeit.The insulator is made of silicone, for example, as this material has a strong insulating effect. Silicone itself has a certain elasticity. It is therefore alternatively conceivable that the insulator and mandrel are designed such that the insulator itself acts as a restoring element, can act in part. Silicone is also very water and dirt repellent. Creepage currents can thus be reduced to a minimum and the service life of the system maximized. Furthermore, silicone has a high temperature and ozone resistance.
Zweckmässigerweise sind eine Stromversorgungseinheit und gegebenenfalls eine Steuerungseinheit montageseitig mit dem Isolator verbunden. Hierbei ist die Stromversorgungseinheit vorteilhafterweise über eine elektrische Verbindung durch den Isolator hindurch mit der Elektrode verbunden.Expediently, a power supply unit and optionally a control unit are connected on the assembly side to the insulator. In this case, the power supply unit is advantageously connected to the electrode via an electrical connection through the insulator.
Zweckmässigerweise kann eine Vibrationseinheit, insbesondere ein Vibrationsmotor, an der Halterung angebracht oder darin integriert werden. Durch Betätigung der Vibrationseinheit, kann die Halterung und somit die befestigte Elektrode in Schwingung gebracht werden. Durch die eingebrachten Schwingungen können abgelagerte Abgaspartikel von der Elektrode abgeschüttelt werden.Conveniently, a vibration unit, in particular a vibration motor, attached to the holder or integrated therein. By operating the vibration unit, the holder and thus the attached electrode can be vibrated. Due to the introduced vibrations deposited exhaust gas particles can be shaken off the electrode.
Vorteilhafterweise ist der zumindest eine Arm zum Halten einer Hochspannungselektrode mit Mitteln zum Aufbau einer lösbaren Verbindung, z.B. einer Steckverbindung oder einer Schraubverbindung, ausgeführt. Hierbei kann der zumindest eine Arm zum Halten der Hochspannungselektrode mit weiteren rückstellenden Elementen ausgeführt sein. Zusätzlich oder alternativ kann das zumindest eine Montagemittel, gegebenenfalls über zumindest ein Trägermittel, mit mehreren Rückstellelementen ausgeführt sein.Advantageously, the at least one arm for holding a high-voltage electrode is provided with means for establishing a releasable connection, for example a plug-in connection or a screw connection. In this case, the at least one arm for holding the high-voltage electrode can be designed with further restoring elements. Additionally or alternatively, the at least one mounting means, if appropriate via at least one carrier means, can be designed with a plurality of reset elements.
Diese und weitere Vorteile und vorteilhafte Ausführungsformen werden im Folgenden aufgezeigt.These and other advantages and advantageous embodiments are shown below.

Die beschriebene flexible Lagerung des Hochspannungsisolators 31 und der Hochspannungselektrode 13 führt dazu, dass die Elektrode 13 bezugsweise die Elektrodenführung 15, zum Beispiel einer von einem Reinigungsbesen 45 ausgehenden Kraft ausweicht. Ein Verklemmen oder Einhängen des Reinigungsbesens 45 an der Elektrode 13 oder Elektrodenführung 15, sowie eine Deformation der Elektrode 13 oder Elektrodenführung 15 kann mit dieser Anordnung verhindert werden.

Im Folgenden werden Elektrodenhalterung 48 oder 49 und Elektroden 13 in funktioneller Hinsicht beschrieben. Das Abgas das im Abgaskanal 9 eines Kamins mit einer beschriebenen Filteranlage 11 oder 12 hochsteigt wird im Durchgang in der Nähe der Elektrode 13 feldionisiert. Hierbei werden Staubpartikel elektrostatisch aufgeladen und auf der Gegenelektrode niedergeschlagen. Die Innenfläche des Abgaskanals 9 kann hier zum Beispiel als Gegenelektrode dienen. Der sich bildende Partikelstaubniederschlag wird in kleineren Anlagen, wie zum Beispiel in privaten Kaminfeueranlagen und Holzheizungen, von Zeit zu Zeit vom Kaminfeger entfernt. Bei der erfindungsgemässen Anlage kann die Reinigung von unten oder von oben erfolgen. Die Vorgehensweise ist jedoch oft länderspezifisch vorgeschrieben.Hereinafter,
Bei der Reinigung von unten, das heisst vom Feuerplatz oder vom Heizungsraum aus, werden Reinigungsbesen und -bürsten 45 gegebenenfalls von Hand nach oben geschoben. Ist die Elektrode 13 selbst flexibel oder deren Halterung 48 oder 49 flexibel gelagert, wird die Elektrode 13 und gegebenenfalls die flexible Elektrodenhalterung 48 oder 49 durch die Bürste 45 zur Seite und/oder nach oben geschoben. Die Elektrode 13 bildet somit kein Hindernis für die vorgeschriebene Reinigung. Die Reinigung kann schnell und gefahrlos durchgeführt werden.When cleaning from below, ie from the fire place or from the boiler room, cleaning brushes and brushes 45 may be pushed up by hand. If the
Zur Reinigung oder bei Wartungsarbeiten von oben, das heisst vom Dach her, kann die flexible Elektrodenhalterung 48 oder 49 aufgrund ihrer Flexibilität einfach zur Seite gedrückt werden und gegebenenfalls die Elektrode 13 abgenommen werden. Zur Abnahme der Elektrode 13 wird diese, bezugsweise die Elektrodenführung 15 oder 16, aus ihrer Halterung gezogen und durch die Elektrodeneinführungsöffnung 25 aus dem Abgaskanal 9 entfernt. Sofern eine flexible Elektrode 13 (wie z.B. Elektrode 67 oder 96 gemäss
Es ist denkbar bei der Reinigung vom Dach aus die Elektrodenhalterung 48 oder 49 und die Elektrode 13 aufgrund ihrer Flexibilität ohne Demontage lediglich zur Seite zu schieben und die Reinigungsbürste von der Abgasaustrittsöffnung 95 oder von der Elektrodeneinführungsöffnung 25 her in den Abgaskanal 9 einzuführen.It is conceivable during cleaning from the roof, the
Ist lediglich eine flexible Elektrode 13 (wie z.B. Elektrode 67 oder 96 gemäss Figur 5) montiert, die Elektrodenhalterung jedoch steif (z.B. wenn die Federn 43, 55, 56, 57, 59 gemäss
Die rückstellenden Federkräfte sind alle so ausgelegt, dass sich die Federn unter den Kräften die bei Reinigung und Wartung wirken zwar leicht nachgeben, aber dass unter Betriebsbedingungen die Anlagenteile bezüglich des Kamins fest fixiert bleiben und keine Vibrationen aufweisen.The resetting spring forces are all designed in such a way that the springs give way slightly under the forces that act during cleaning and maintenance, but that under operating conditions the parts of the plant remain firmly fixed relative to the chimney and have no vibrations.
