Description

Verfahren und-Vorrichtung zur Verhütung oder Verminderung des Mitreißens der von den Elektroden abgelösten Staubteile in elektrischen Entstaubungsanlagen. Bei elektrischen Entstaubungsanlagen, bei denen der an den Elektroden haftende Staub: durch Abreinigungsvorrichtungen entfernt wird, besteht der Mißstand, daß abgelöste Staubteilchen in den Luft- oder Gasstrom geraten und von diesem,'statt zu Boden zu fallen, mitgerissen werden.Method and apparatus for preventing or reducing entrainment of the dust particles detached from the electrodes in electrical dust extraction systems. In electrical dust extraction systems where the dust adhering to the electrodes: is removed by cleaning devices, there is a problem that detached Dust particles get into the air or gas stream and from it, instead of falling to the ground to fall, to be carried away.

Dieser Übelstand wird nach der Erfindung dadurch beseitigt oder verringert, daß die an den Elektroden haftenden Staubteile vor ihrer Loslösung einem Druck ausgesetzt werden, durch den ein Zusammendrücken von Teilchen, also eine Klümpchen- oder Plättchenbildung, erfolgt. Diese gröberen und dichteren Körperchen werden von dem Luft- oder Gasstrom nicht, oder doch weniger leicht, mitgenommen.According to the invention, this deficiency is eliminated or reduced by that the dust particles adhering to the electrodes are subjected to pressure before they are released due to the compression of particles, i.e. the formation of lumps or platelets, he follows. These coarser and denser particles are released by the air or gas flow not, or at least less easily, taken along.

Die Zeichnung stellt ein Beispiel einer hierfür dienenden Vorrichtung schematisch dar.The drawing shows an example of a device used for this purpose schematically.

Im Gehäuse i läuft die als Niederschlagelektrode dienende Trommel n um, während ihr eine Sprühelektrode l konzentrisch gegenüberliegt. Die Einströmung der Luft oder des Gases findet bei a, die Ausströmung bei b statt. Am tiefsten Punkte der Trommel n befindet sich eine Abreinigungsvorrichtung h beliebiger Art. Der abgelöste Staub verläßt das Filter bei c. Vor der Abreinigungsvorrichtung, im Sinne der Dreh. richtung der Trommel n verstanden, ist eine unter Federdruck stehende Walze g ange. bracht, die kräftig gegen die Trommel n drückt und so die auf dieser haftenden Staubteilchen zu Plättchen oder Klümpchen zusammenballt, bevor sie durch die- Abreinigungsvorrichtung h abgelöst werden.The drum serving as a precipitation electrode runs in the housing i n um, while a spray electrode l is concentrically opposite it. The inflow the air or gas takes place at a, the outflow at b. At the lowest point the drum n is a cleaning device h of any type. The detached Dust leaves the filter at c. In front of the cleaning device, in the sense of turning. Understood direction of the drum n, a spring-loaded roller g is ange. Bracht, which presses forcefully against the drum n and so the dust particles adhering to it agglomerates into platelets or lumps before passing through the cleaning device h to be replaced.

PATENTANSPRÜCHE: i Verfahren zur Verhütung oder Verminderung des MltrieißenS der von den Elektroden abgelösten Staubteile in elektrischen Entstaubungsanlagen, dadurch gekennzeichnet, daß die an einer Elektrode haftenden, von ihr mittels einer Abreinigungsvorrichtung loszulösenden Staubmassen vor ihrer Ablösung durch Druck zu größeren Körperchen verdichtet werden. z. Vorrichtung zur Ausübung des Verfahrens nach Anspruch i, dadurch gekennzeichnet, daß am Umfange einer als Niederschlagelektrode dienenden umlaufenden Trommel (n) vor der die angesetzten Staubmassen abnehmenden Abreinigungsvorrichtung (h) eine die Staubteilchen verdichtende federnde Druckwalze (g) angebracht ist. PATENT CLAIMS: i A method for preventing or reducing the flow of dust particles detached from the electrodes in electrical dust extraction systems, characterized in that the dust masses adhering to an electrode and to be detached from it by means of a cleaning device are compressed into larger bodies by pressure before they are detached. z. Device for carrying out the method according to claim i, characterized in that a resilient pressure roller (g) compressing the dust particles is attached to the circumference of a rotating drum (s) serving as a precipitation electrode in front of the cleaning device (h) which removes the deposited dust masses.
