Abstract

The wet-type dust suppressor comprisesd, on the secondary air side, a contact zone in which is mounted a Zn and/or Sn grid for binding the Hg into a amalgam. this solves the problem in various chemical smelting and metal melting processes, in which large quantities of vapours enriched with Hg are released, causing pollution of the environment. Normally, the Hg-contg. vapours cannot readily be scrubbed with water and pptd. so that they have to be added to the scrubbing liq. with relatively high energy consumption in order to obtain sufficient scrubbing.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

'Naßentstauber zur Reinigung von Quecksilberdämpfen' Bei den verschiedensten chemischen Verhüttungs- und Metall-Schmelzprozessen werden vielfach Dämpfe, die mit Quecksilber angereichert sind, freigesetzt. Diese für Mensch und Umwelt schädlichen Dämpfe müssen entsorgt werden.'Wet dust extractors for cleaning mercury vapors' for a wide variety of chemical smelting and metal smelting processes are often vapors that enriched with mercury are released. These are harmful to humans and the environment Vapors must be disposed of.

Da aber diese quecksilberhaltigen Dämpfe nicht gut mit Wasser auszuwaschen und abzuscheiden sind, müssen sie mit relativ hohem Energiebedarf an die Waschflüssigkeit angelagert werden, um einen genügend hohen Wascheffekt zu erzielen.But since these mercury-containing vapors cannot be washed off well with water and are to be separated, they have to be fed to the washing liquid with a relatively high energy requirement be deposited in order to achieve a sufficiently high washing effect.

Um den Auswascheffekt zu verbessern wird erfindungsgemäß vorgeschlagen, den Naßentstauber so zu gestalten, daß eine metallische Bindung des Quecksilbers zum Amalgan geschaffen wird.In order to improve the washout effect, it is proposed according to the invention that to design the wet dust extractor so that a metallic bond of the mercury is created into the amalgan.

Dieses wird erfindungsgemäß dadurch erzielt, indem man auf der Sekundärluftseite des Naßwäschers ein Zinn- und /oder Zinkgitter einsetzt.According to the invention, this is achieved by on the secondary air side of the wet scrubber uses a tin and / or zinc grid.
