Abstract (en)

An electrostatic filter, comprising an inlet ionizer with flexible electrodes (7, 8) and an outlet collector (5) with an earthed filter mat (16), is new. An electrostatic filter has a filter cell with an inlet-side ionizer and an outlet-side collector, the ionizer being fitted in a frame and having electrodes extending across the flow cross-section. The electrodes (7, 8) are fixed at one end in the frame (6) and can flex at the other end and the collector (5) comprises an earthed filter mat (16) of wire wool or the like covering the flow cross-section.

Abstract (de)

Ein Elektrofilter, insbesondere zur Abluftreinigung für Straßentunnel, Tiefgaragen od. dgl., besteht aus wenigstens einer einen Durchströmkanal (3) bildenden Filterzelle (1) mit einer einströmseitigen lonisiereinrichtung (4) und einem ausströmseitigen Kollektor (5), wobei die lonisiereinrichtung (4) in einem Rahmen (6) eingesetzte, sich über den Strömungsquerschnitt erstreckende Elektroden (7, 8) aufweist. Um einen auch hohen Temperaturen standhaltenden Elektrofilter mit hoher Abscheideleistung und guter Reinigungsmöglichkeit zu schaffen, sind die Elektroden (7, 8) einerends fest und andernends federnd nachgiebig im Rahmen (6) eingespannt und ist als Kollektor (5) eine geerdete, den Strömungsquerschnitt überdeckende Filtermatte (16) aus Drahtwolle od. dgl. vorgesehen. <IMAGE>
