The invention relates to a collecting electrode for electrostatic dust collectors two opposing plastic layers and a conductive film arranged between them.

It is known that the collecting electrodes of the gas to be cleaned are such corrosive Are exposed to attacks that a great wear of the electrodes occurs. To extend the life of the To raise the collecting electrodes, the electrodes were coated with an electrically conductive varnish. Furthermore, electrodes have become known which are provided on both sides with a glass layer or a highly corrosion-resistant, electrically conductive layer of a certain specific sheet resistance are covered.

Further improvements should be achieved by making conductive, semiconducting material existing intermediate layers form trapping spaces for the separated material or the non-spraying electrode was clad with a massive semiconductor, ao Finally, corrugated sheet-like electrodes were also used Provided with perforated sheet metal plates on both sides to avoid gas flow losses Holes widen towards the electrode. According to another known embodiment are opposite the perforations of box-shaped collecting electrodes arranged spray tips.

According to the invention, the disadvantages of the aforementioned proposals are to be eliminated in that the plastic layers have a large number of offset conical perforations exhibit. It is particularly advantageous for the number of holes to be conical in the direction of the film and form depressions of the same size in the plastic layers.

A precipitation electrode according to the invention is shown, for example, in the drawings. It shows

F i g. 1 shows the plan view of a precipitation electrode, FIG. 2 shows a section along the line AB in FIG. 1.

The plastic plates 1, 2 cover the metal foil 3 in a form-fitting and material fit. The equally large electrostatic precipitation electrodes provided in the plastic plates 1, 2, conically extending in the direction of the film 3 and of the same size

Holes 4 forming wells are arranged offset from one another in such a way that in the Section (FIG. 2) results in a wave-like shape, so that a wave crest 5 lies opposite each wave valley 4. It is within the meaning of the invention that the collecting electrode is in the form of an endlessly circumferential belt-shaped Electrode can be formed.
