Description
Verfahren zur elektrischen Reinigung von heisse Dämpfe enthaltenden Gasen. Die vorliegenide Erfindung betrifft ein Verfahren zur Reinigung von heisse Dämpfe, zum Beispiel auch Metall@dämpfe, enthalten den Gasen, wobei die in Eden Gasen enthal tenen Teilehen durch ein Elektrofilter ab- geschieden werden sollen.
Die Abscheidung macht bei Jerartigen Gasen häufig Schwie rigkeiten, da die ausserordentlich trockenen Schwebeteilchen sich nur sehr schwer :ab scheiden lassen. Die Erfindung zeigt nun ein Verfahren, durch Idas man die Gase in einen Zustand ;bringen kann, in dem @die Absühei- dung der Schwebeteilchen erheblich leichter vor sich geht.
Erfindungsgemäss wenden den heisse Dämpfe enthaltenden -Gasen vor ihrem Ein tritt in das Reinigungsfilter kältere Gase, zum Beispiel Luft, beigemischt, so dass hier durch Teilnebel entstehen, welche die Ab- scheidung der in dien Gasen, enthaltenen Schwebeiteilchen erheblich @erleichtert. Die durch eine ,

Das Ver fahren besitzt ferner den Vorteil, dass durch Re,gelunfg der zumeführten @Gasmenge eine allzu grosse Befeuchtung der Niederschlags flächen vermieden werden kann.
Gegebenen falls können .auch Vorrichtungen vom an sich bekannter Art vorgesehen sein, die zum Bei spiel durch ein Thermometer aller Hygro meter gesteuert wenden und eine allzu starke Abkühlung bezw. Befeuchtung der Gase selbsttätig verhindern.
Ferner können die Regelun;gvvorrich- tungen für die -zugeführte Gasmenge auch durch die Stromänderungen des dürch das Elektrofilter hindturchgehenden .elektrischen Stromes besteuert werden, @da iIer Filterstrom in Abhängigkeit von Odem Feuchtigkeits- gehalt ider Gase steht.
Je trockener idie zu

Process for the electrical cleaning of gases containing hot vapors. The present invention relates to a method for cleaning hot vapors, for example also metal vapors, contained in the gases, whereby the parts contained in Eden gases are to be separated off by an electrostatic precipitator.
Separation is often difficult with Jer-like gases, since the extremely dry suspended particles are very difficult to separate. The invention now shows a method by which the gases can be brought into a state in which the separation of the suspended particles is considerably easier.
According to the invention, the gases containing hot vapors are mixed with colder gases, for example air, before they enter the cleaning filter, so that partial mist is created here which considerably facilitates the separation of the suspended particles contained in the gases. Which by one
The condensate particles produced in this way have the property that they strive to a large extent: to charge themselves electrically and then to change towards the surface of the precipitation and to settle there.
The method also has the advantage that overly great humidification of the precipitation areas can be avoided by controlling the amount of gas supplied.
If necessary, devices of the type known per se can be provided, which, for example, turn controlled by a thermometer of all hygro meters and too strong cooling respectively. Prevent humidification of the gases automatically.
Furthermore, the regulating devices for the amount of gas supplied can also be taxed by the changes in the electrical current passing through the electrostatic precipitator, since the filter current is dependent on the moisture content of the gases.
The drier it is too
EMI0001.0075
cleaning gases, the lower their conductivity and the lower the current that passes through the filter.
On the other hand, the more humid the gases are, the greater is the amount of electricity flowing through the filter. These. Current: fluctuations can be used, for example, to control relays or the like, which move adjustable valves for supplying beer-cold gases in the desired manner.
