Abstract

The central wire discharge electrode is fixed to a pivoting- or sliding holder. This allows it to be displaced from the norm coaxial location, to one side, close to the inner wall of the tube. Preferred features: Numerous tubular electrodes (2) are arranged in a common casing, with dust hopper below. Discharge electrodes (3) (the central wires) are secured to a common holder (6), which can be slid or pivoted. Axes of the cylindrical electrodes are distributed evenly around circle(s). The common holder for the wires is star-shaped, the tips lying on the circle and the center forming the pivoting center.

Description

Die Erfindung bezieht sich auf einen Röhrenelektrofilter mit wenigstens einer rohrförmigen Niederschlagselektrode und jeweils einer koaxial angeordneten draht- oder stabförmigen Ausströmelektrode.The invention relates to a tubular electrostatic precipitator with at least one tubular precipitation electrode and each a coaxially arranged wire or rod Outflow electrode.

Als Elektrofilter werden Anlagen zur Entstaubung von zumeist industriellen Gasen, wie Gichtgasen, Rauchgasen oder dgl. benannt. Die Wirkungsweise beruht auf dem Korona-Effekt und bezeichnet eine elektrische Entladungsform, die an scharfen Kanten, an Spitzen oder an Drähten bei Atmosphärendruck und hohen Spannungen auftritt. Elektrofilter bestehen aus einer zumeist auf 35 bis 75 kV aufgeladenen Sprühelektrode, der eine geerdete Niederschlagselektrode in entsprechender Entfernung gegenübersteht. Die Niederschlagselektrode muß eine hinreichend große Oberfläche für den Niederschlag der ausgefilterten Staubteilchen aufweisen und ist zumeist mit einer Vorrichtung zum Abschütteln des Niederschlages verbunden. Durch die angelegte hohe Spannung wird das durchströmende Gas ionisiert, wobei in dem elektrischen Kraftfeld zwischen den beiden Elektroden ein gerichteter Strom von negativen Gasionen in Richtung zum geerdeten Rohr wandern. Wenn durch einen derartigen Elektrofilter nun ein Gas mit festen oder flüssigen Schwebestoffteilchen gefördert wird, so werden diese von den Ionen bombardiert und laden sich gleichfalls negativ auf. Infolge des elektrischen Feldes werden die geladenen Teilchen zur Niederschlagselektrode hingetrieben.Systems for dedusting are mostly used as electrostatic precipitators industrial gases, such as top gases, flue gases or the like. named. The mode of action is based on the corona effect and is called an electrical discharge form that is sharp Edges, on tips or on wires at atmospheric pressure and high voltages occur. Electrostatic filters usually consist of a on 35 to 75 kV charged spray electrode, which is a grounded Precipitation electrode at an appropriate distance faces. The precipitation electrode must be sufficient large surface area for the precipitation of the filtered dust particles have and is mostly with a device for shaking of precipitation. Due to the high The gas flowing through is ionized, whereby in the electric force field between the two electrodes a directed Stream of negative gas ions towards the grounded Hiking tube. If by such an electrostatic precipitator Pumped gas with solid or liquid suspended particles is bombarded by the ions and charged also negative. As a result of the electric field the charged particles are driven towards the precipitation electrode.

Neben Röhrenelektrofiltern, bei welchen eine drahtförmige Ausströmelektrode von einem geerdeten Zylinder umgeben ist, sind auch andere Bauformen, wie beispielsweise Plattenelektrofilter, bekannt.In addition to tubular electrostatic precipitators, in which a wire-shaped Outflow electrode is surrounded by a grounded cylinder also other designs, such as plate electrostatic precipitators, known.

Bei der Verwendung von derartigen Röhrenelektrofiltern für die Reinigung beispielsweise von Biofeuerungsabgasen stellen sich in der Folge eine Reihe von aufwendigen Reinigungsproblemen, da in derartigen Biofeuerungsabgasen auch teerartige, bituminöse Partikel enthalten sind, welche gemeinsam mit den Staubteilchen eine gut haftende Schicht an der Innenwand der Niederschlagselektrode ergeben. Derartige Filter bedürfen daher einer relativ häufigen Reinigung, wobei mit Rücksicht auf die Anwesenheit von klebrigen, bituminösen Teilchen ein einfaches Abschütteln in der Regel nicht ausreicht, um die Oberflächen der Abscheidungs- bzw. Niederschlagselektrode wieder von dem Niederschlag zu befreien. Derartige Filter müssen daher mechanisch gereinigt werden, wofür Bürsten eingesetzt werden können. Bei Röhrenfilter wird aber die Reinigung der Innenwand der zylinderförmigen Niederschlagelektrode durch die Ausströmelektrode behindert.When using such tube electrostatic filters for the cleaning of, for example, bio-combustion exhaust gases as a result, a number of complex cleaning problems since in such biofuel exhaust gases also tar-like, bituminous particles are contained, which together with the Dust particles have a well adhering layer on the inner wall of the Precipitation electrode result. Such filters therefore need a relatively frequent cleaning, taking into account the Presence of sticky, bituminous particles a simple Shaking off is usually not enough to cover the surfaces of the Deposition or precipitation electrode again from the precipitation to free. Such filters must therefore be cleaned mechanically what brushes can be used for. At Tube filter is cleaning the inner wall of the cylindrical Precipitation electrode hindered by the discharge electrode.

Die Erfindung zielt nun darauf ab, einen Röhrenelektrofilter der eingangs genannten Art zu schaffen, welcher auch für die Verwendung in Biofeuerungsanlagen geeignet ist und in besonders einfacher Weise mechanisch gereinigt werden kann. Zur Lösung dieser Aufgabe ist der erfindungsgemäße Röhrenelektrofilter so ausgebildet, daß die Ausströmelektrode an einem verschwenkbaren oder verschiebbaren Halteteil festgelegt ist und aus der zur Niederschlagselektrode koaxialen Lage in eine der Innenwand der rohrförmigen Niederschlagselektrode benachbarte Lage verschieb- oder verschwenkbar ist. Dadurch, daß die Ausströmelektrode, welche als Draht oder Seil ausgebildet sein kann, in geeigneter Weise verschoben oder verschwenkt werden kann und in eine der Innenwand der rohrförmigen Niederschlagselektrode benachbarte Lage verbracht werden kann, kann in den nunmehr freigegebenen lichten Querschnitt der Niederschlagselektrode ein entsprechendes Reinigungsgerät, beispielsweise eine Rohrbürste oder dgl., eingeführt werden und effiziente rasche Reinigung erfolgen. Vor der neuerlichen Inbetriebnahme ist es lediglich erforderlich die Ausströmelektrode wiederum in ihre im wesentlichen koaxiale Lage zum Mantel der zylinderförmigen bzw. rohrförmigen Niederschlagselektrode zurück zu verschieben und zu verschwenken, um auf die Art und Weise die geeignete Ausbildung des Korona-Effekts und die gewünschte gerichtete Strömung beim neuerlichen Reinigungsvorgang zu gewährleisten.The invention now aims to provide a tubular electrostatic precipitator to create of the type mentioned, which also for the use in bio-firing systems is suitable and in can be cleaned mechanically in a particularly simple manner. For The tube electrostatic filter according to the invention solves this problem formed so that the discharge electrode on a pivotable or slidable holding part is fixed and from the position coaxial to the precipitation electrode into one of the Inner wall of the tubular precipitation electrode adjacent Position is displaceable or pivotable. Because the discharge electrode, which are designed as wire or rope can be moved or pivoted in a suitable manner can and in one of the inner wall of the tubular precipitation electrode neighboring location can be spent in the now released clear cross section of the precipitation electrode a corresponding cleaning device, for example a pipe brush or the like, are introduced and efficient quick cleaning. Before starting up again it is only necessary to turn the discharge electrode in their essentially coaxial position to the jacket of the cylindrical or tubular precipitation electrode to move back and swivel to find the appropriate one Formation of the corona effect and the desired directed To ensure flow during the new cleaning process.

In besonders vorteilhafter Weise ist die Ausbildung erfindungsgemäß so getroffen, daß eine Mehrzahl von zylinderförmigen Niederschlagselektroden in einem gemeinsamen Gehäuse angeordnet ist, an dessen unterem Ende ein Staubtrichter angeschlossen ist und daß die Ausströmelektroden auf einem gemeinsamen Halteteil festgelegt und mit diesem verschieb- oder verschwenkbar angeordnet sind. Mit einer derartigen eine Mehrzahl von zylinderförmigen Niederschlagselektroden aufweisenden Filtereinrichtung lassen sich auch große Gasmengen mit kleinbauenden Filtern zuverlässig reinigen, wobei die erforderliche Reinigung der Elektroden selbst und insbesondere der Niederschlagselektroden durch die gemeinsame Verschwenkung bzw. Verschiebung der Ausströmelektroden mit geringsten Stillstandszeiten ermöglicht wird.The design according to the invention is particularly advantageous made so that a plurality of cylindrical Precipitation electrodes in a common housing is arranged, at the lower end of which a dust hopper is connected is and that the discharge electrodes on a common Holding part fixed and slidable or pivotable with this are arranged. With such a majority of cylindrical filter devices having precipitation electrodes large quantities of gas can also be Clean filters reliably, doing the necessary cleaning the electrodes themselves and in particular the precipitation electrodes through the joint pivoting or shifting the discharge electrodes with minimal downtimes becomes.
