"Elektrödenfreies mit der Waschflüssigkeit aufgeladenes elektrostatisches Sprühfilter zur Auswaschung"Electrode-free charged with the washing liquid electrostatic spray filter for washing out
von Gasen" ~ .,. ,of gases "~.,.,
Zusatzanmeldung zur Hauptanmeldung P 22 43 926.5Additional registration to the main registration P 22 43 926.5
Bekannt ist nach der Hauptanmeldung die Einsprühung von geladenen Flüssigkeitstropfen.According to the main application, the spraying is known of charged drops of liquid.
Die Aufladung der Waschflüssigkeitstropfen ist sehr schwierig, da die Versprühung unter Druck erfolgen muß und damit die Druckerzeugungs-Aggregate und Vorratsbehälter ein hohes Potential erhalten und damit entsprechend isoliert werden müssen, bzw. wie bereits erfindungsgemäß vorgeschlagen, durch Zwischenspülbehälter eine galvanische Trennung erfolgen muß.The charging of the drops of washing liquid is very difficult because the spraying must take place under pressure and thus the pressure generating units and reservoirs receive a high potential and thus accordingly must be isolated, or as already proposed according to the invention, by intermediate flushing containers galvanic separation must be provided.
Erfindungsgemäß wird vorgeschlagen, die Aufladung des Sprühwassers in einem HF-Transformator vorzunehmen.According to the invention it is proposed that the charging of the Water spray in an HF transformer.
Das Schema einer solchen Einrichtung zeigt die heiliegende erfindungsgemäße Abbildung.The scheme of such a facility shows the healing one Figure according to the invention.
Das Rohgas tritt bei (1) in den Waschturm (14) ein und durchwandert nach oben strömend oder auch mit der Flüssigkeit strömend die Sprühzone (13).The raw gas enters the scrubbing tower (14) at (1) and wanders through flowing upwards or with the Liquid flowing through the spray zone (13).

Im Bereich 18 tritt das Rohgas in einen Radialdi ff usor ein und wird hier in eine Drehströmung versetzt und somit in bekannter Weise über Schälringe in der Schlammkammer 3 von mitgeschlepptem Wasser befreit. In the area 18, the raw gas enters a radial diffuser and is set in a rotary flow here and thus freed of entrained water in a known manner via peeling rings in the sludge chamber 3.
Es kann natürlich auch hier ein normaler Tropfenabscheider Anwendung finden.A normal mist eliminator can of course also be used here.
Das gereinigte Gas tritt aus dem Stutzen 2 aus.The cleaned gas emerges from the nozzle 2.
Der Ventilator 5 liefert den notwendigen Unterdruck für den Gasdurchlauf.The fan 5 supplies the necessary negative pressure for the gas flow.
Das Reingas verläßt die Anlage am Stutzen 12.The clean gas leaves the system at nozzle 12.
Der HF-Generator liefert eine hohe gespannte HP-Energie, die zu einem HF-Transformator geleitet wird.The HF generator delivers high voltage HP energy, which is conducted to an HF transformer will.
Die Krümmerwicklung 15 besteht aus einer handelsüblichen Kupferwicklung, während die Wicklung 16 aus Kunststoff oder auch aus Metallrohr besteht.The manifold winding 15 consists of a commercially available copper winding, while the winding 16 consists of Plastic or made of metal pipe.
Durch das Rohr wird aus einem Behälter 20 die Waschoder Benetzungsflüssigkeit, die aus Wasser oder Natronlauge usw. bestehen kann, durch die Pumpe über dieThe washing or wetting liquid, which consists of water or sodium hydroxide solution, is transferred from a container 20 through the pipe etc. may exist by the pump over the

Wicklung 16 zur Sprühdüse 2 in den Waschturm 14 gepumpt. .Winding 16 to the spray nozzle 2 in the washing tower 14 pumped. .
Beim Durchfließen der Traforohrwicklung 16 wird die Flüssigkeit unter Höchst-Spannurig gesetzt.When flowing through the transformer tube winding 16, the liquid is placed under maximum tension.
Durch Erdung an der Stelle 17 bleiben alle Einrichtungen vor Eintritt in die Wicklung potential frei.By earthing at point 17, all facilities remain potential-free before entering the winding.
Aus der Düse 8 tritt das Wasser in Tropfenform auf und ist je nach Phasenlage bei der Ablösung verschieden stark geladen und verschieden gepolt geladen.From the nozzle 8 the water occurs in the form of drops and is different depending on the phase position in the detachment heavily charged and charged with different polarity.
Hiedurch werden im wesentlichen 2 Effekte erzielt.This essentially produces two effects.
1. Es werden elektfo-statische Kräfte auf Stäube, die sowohl positiv als auch negativ und auch solche, die neutral geladen sind, ausgelöst.1. There are electrostatic forces on dust, which both positive as well as negative and also those that are neutrally charged.
2. Durch die Tropfen untereinander unterschiedlichen Potentialverhaltens tritt nach einer gewissen freien Weglänge auch eine laufende Agglomeration der Tröpfchen ein, sodaß die Feinstnebe!tröpfchen sich zu großen Tropfen verbinden und damit leicht abscheidbar werden.2. Different from each other due to the drops After a certain free path, a continuous agglomeration of the potential behavior occurs Droplets, so that the finest levels! Droplets combine to form large droplets and are thus easily separable.

Durch den Einbau geeigneter Abscheideringe 21 und 22 wird der Tropfenweg beeinflußt und verbessert von der Wand in mehrere Ebenen verlagert.By installing suitable separator rings 21 and 22, the drop path is influenced and improved shifted from the wall in several levels.
Zweckmäßigerweise wird der Samme!trichter 21 geerdet, ebenso der obere Abscheideschälmantel.The collecting funnel 21 is expediently earthed, likewise the upper separating peeling jacket.
Die Sprüh- oder Benetzungsflüssigkeit wird schließlich über die Rohrleitungen 23 aus dem unteren Trichter abgezogen, wo sich ebenfalls das aus der Abscheidekammer ausfallende über die Leitung 4 zugeführte Wasser einsammelt.The spray or wetting liquid is finally via the pipes 23 from the The lower funnel is withdrawn, where the falling out of the separation chamber is also spread over the Line 4 collects supplied water.
über die Pumpe 24 wird das Wasser in die Trenneinrichtung 7 gepumpt, wo die Abscheidung über den Stutzen 6 abgeführt wird und gelangt dort über die Leitung 23 zurück zum Sammelbehälter 20, von wo aus der Kreislauf von neuem beginnt.The water is fed into the separating device via the pump 24 7 is pumped, where the separation is discharged via the nozzle 6 and arrives there via the Line 23 back to the collecting container 20, from where the cycle begins again.
Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten und beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, einen elektro-statisch arbeitenden NaßfilterOf course, the invention is not limited to those shown and described in detail above Forms of training limited, but numerous changes are possible without, however, from the basic idea to deviate, an electrostatically working wet filter
