Description

Durchlässige Elektrode für elektrische Gasreinigung Bei durchlässigen Elektroden für eIektrische Gasreinigungsapparate zeigt sich bei höheren Gasgeschwindigkeiten der Übelstand, daß die an der Elektrode bereits abgeschiedenen Staubteilchen durch den. Gasstrom von den Flächen wieder losgerissen und mitgeführt werden. Letzteres ist besonders dann möglich, wenn die Schüttelvorrichtung der Abscheideelektroden in Tätigkeit gesetzt wird. Diese Gefahr wird -er$ndungsgemäß dadurch vermieden, daß an der Elektrode senkrechte oder nahezu senkrechte Prallflächen angebracht werden, die mit .Randleisten versehen sind. Die sich absetzenden Staubteilchen stoßen an diese Flächen an und werden durch die Randleisten vor dem Wegspülen durch .den Gasstrom geschützt. Die senkrecht angeordneten Prallflächen mit den Randleisten, die einen C förmigen Querschnitt haben können, bilden dann. gewissermaßen Kanäle, die bis zu dem Sammeltrichter heruntergefühxt sind. Ein waagerechter Querschnitt durch ein derartiges Filter ist als Ausführungsbeispiel in der Zeichnung dargestellt. i sind die Hochspannungselektroden, z netzförmige Abscheideelektroden und 3 die an letzteren angeordneten Pralllkörper. Durch Pfeile ist der Weg des Gasstromes angedeutet. Der größte Teil der Staubteilchen wird sich in den Prallkörpern absetzen und in ihnen hinab in den Sammeltrichter fallen.Permeable electrode for electrical gas purification With permeable electrodes for electrical gas purification apparatus, at higher gas velocities there is the disadvantage that the dust particles already deposited on the electrode are caused by the. Gas flow can be torn loose again from the surfaces and carried along. The latter is particularly possible when the shaking device for the separation electrodes is activated. According to the invention, this risk is avoided in that vertical or almost vertical impact surfaces are attached to the electrode and are provided with edge strips. The settling dust particles hit these surfaces and are protected by the edge strips from being washed away by the gas flow. The vertically arranged baffles with the edge strips, which can have a C- shaped cross-section, then form. as it were, channels that are felt down to the collecting funnel. A horizontal cross section through such a filter is shown as an exemplary embodiment in the drawing. i are the high-voltage electrodes, z reticulated separation electrodes and 3 are the baffles arranged on the latter. The path of the gas flow is indicated by arrows. Most of the dust particles will settle in the impact bodies and fall down into the collecting funnel.
