ークＩＩ第１６巻、１９７０年、１１９頁参照）。The scrubbing tower is upright within the framework of the invention due to the vertically arranged flow channels as JE, in which the purification of the gas stream takes place by scrubbing. A plurality of individual spray nozzles or a plurality of aggregations of a plurality of spray nozzles can be arranged in parallel below the washing tower axis -L. Wet cleaning refers to the cleaning process in the area of the spray nozzle and the subsequent removal of dust by 6+1! It represents middle separation. It is clear that the cleaning water can also absorb gaseous components. The washing tower may be equipped with a ring gap washer.

は４角形断面を持った比較的細い線材が使われる。According to principle, electrical filters are cylindrical or plate capacitors. Between the field electrodes, a DC voltage of approximately 20,000 to 70,000 V and above, as far as possible below the breakdown limit, is applied, which is usually generated from an AC or three-phase AC power supply network by means of a high-voltage transformer and a rectifier. be done. The negative side of the rectifier output terminal is connected to corona electrodes with the smallest possible radius of curvature, from which the electrodes emerge. In most cases -
Corona electrodes are made of relatively thin wires, often with barbs and sometimes with a rectangular cross section.

れている。The positive pole of a DC power supply is generally grounded, and the collecting electrode is also grounded. However, in principle, the polarity may be reversed. Within the framework of the invention, as usual, the corona electrode is connected to the negative side of the rectifier output terminal, and the electrodes around one are grounded. However, within the scope of the invention it is also possible to operate with reverse polarity. The process in an electric filter is the same as that of a self-sustaining discharge, passing current from a corona electrode to an electrode of opposite polarity. The raw gas travels between the electrodes. The entrained dust particles or dust-fine liquid droplets are mostly negatively charged and move toward the collection electrode in a typical corona electrode assembly. These particles release their charge here and are ejected. In devices such as those mentioned at the beginning, which are well known from experience, the corona electrode assembly is part of an electrical filter, in which a collecting electrode surrounds the corona electrode. The assembly as a whole has sufficient length to also allow evacuation at the collecting electrode after charging of the lump. This is followed by a wet cleaner. In this respect, two dust removal devices are being integrated into a unit.
