Abstract
Description
Der denaturierende Teil des Elektrofilters, d. h. die sog. Niederschlagselektrode hat entsprechend der Hauptanmeldung eine denaturierende Eigenschaft. Diese wird erfindungsgemäß dadurch gewährleistet, daß Tränkungen, die im Material der Niederschlagselektrode vorhanden sind einen hohen und/oder niedrigen pH-Wert, z. B. pH- Wert 1 bis 14 garantieren. Hierdurch wird die denaturierende Wirkung auf die abgeschiedenen Stoffe gewährleistet und es können z. B. keine Endotoxine entstehen.The denaturing part of the electrostatic filter, i.e. H. has the so-called precipitation electrode a denaturing property according to the main application. This will according to the invention thereby ensures that impregnations in the material of the Precipitation electrodes are present with a high and / or low pH, e.g. B. pH Guarantee value 1 to 14. As a result, the denaturing effect on the deposited Guaranteed fabrics and it can, for. B. no endotoxins arise.
Sichergestellt werden muß jedoch, daß die denaturierenden Eigenschaften des Materials der Niederschlagselektrode unter allen wechselnden Betriebsbedingungen wie z. B. unterschiedlicher Luftfeuchtigkeit gewährleistet ist.However, it must be ensured that the denaturing properties of the material Precipitation electrode under all changing operating conditions such as B. different humidity is guaranteed.
Aus diesem Grunde wird erfindungsgemäß vorgeschlagen, die Matten auf der Niederschlagselektrode oder das Material was auf der Niederschlagselektrode ausgebildet ist mit Substanzen zu versehen, die Salze enthalten, Kali- und/oder Natriumsalze, die durch Flüssigkeitsaufnahme praktisch flüssig sind und nach dem Abtrocknen Kristallkörper bilden. Die denaturierende Schicht wird durch Luftfeuchtigkeit der vorbeistreichenden, zu reinigenden Luft, ständig aktiv gehalten indem durch die hygroskopischen Eigenschaften der Salze Feuchtigkeit aufgenommen wird und eine denaturierende Phase im pH-Wert z. B. Bereich 12 bis 14 oder im Bereich 1 bis pH-Wert 3 vorliegt. For this reason, the invention proposes that the mats on the Precipitation electrode or the material that is formed on the precipitation electrode to be provided with substances which contain salts, potassium and / or sodium salts which Liquid absorption are practically liquid and form crystal bodies after drying. The denaturing layer is cleaned by the humidity of the passing by Air, kept constantly active by the hygroscopic properties of the salts Moisture is absorbed and a denaturing phase in pH z. B. Area 12 to 14 or in the range 1 to pH 3.
Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen und ausgeführten Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich ohne jedoch von dem Grundgedanken abzuweichen, daß hygroskopische Substanzen in der denaturierenden Oberfläche oder im Körper der Niederschlagselektrode und/oder auch Sprühelektrodenanordnung angeordnet sind, so daß die Feuchte aus der vorbeistreichenden Luft, die gereinigt werden soll, eine stetige Aktivierung des gewünschten denaturierenden Systems garantiert.Of course, the invention is not limited to that described in detail above and executed training forms limited, but there are numerous changes possible without deviating from the basic idea that hygroscopic substances in the denaturing surface or in the body of the precipitation electrode and / or also Spray electrode arrangement are arranged so that the moisture from passing by Air to be cleaned, a constant activation of the desired denaturing Systems guaranteed.
