ならない。Prior art deep bed filter cartridges have fibrous filters. The exhaust gas to be purified flows through this deep-bed filter cartridge in a more or less radial direction 11 towards the pure gas draw-off pipe. The soot particles remain trapped within the fiber structure. Although such deep-bed filter cartridges provide good purification, they become clogged over time during purification and must be cleaned and regenerated from time to time.

ルギ消費な必要とする。In fact, chemical detergents are used for this purpose. Chemical detergents create a nuisance of environmental pollution. It has therefore been attempted to take advantage of the fact that the exhaust gases of internal combustion engines are sufficiently entrained with oxygen, to carry out the cleaning by combustion of the separated soot, and to heat the filter cartridge for this purpose by means of an integrated electric heating wire. It is being Even in this way, the cleaning is only performed very incompletely and also requires considerable energy consumption.

That is, the deep bed filter cartridge is surrounded by at least one soot combustion electrode, which soot combustion electrode is formed or arranged to pass gas, and the soot combustion electrode 5 is connected to a combustion voltage source. and a pure gas extraction tube is connected as a counter electrode.

使用する。In particular, many possibilities of forming and configuring the soot combustion electrode are within the scope of the invention. The soot combustion electrode can be constructed from an electrode wire that is wound around a deep bed filter cartridge in 20 single or multiple spirals. In this case, generally a corrosion-resistant wire, for example 187
A wire made of 8-chromium/nickel steel is used. However, the soot combustion electrode can also be configured as a grid. According to a further proposal of the invention, the soot combustion electrode is constructed as a perforated plate. Corrosion-resistant materials are also used in this respect.

態を前提とする。Utilizes the present invention & Chiaki. That is, if the pure gas draw-off tube is connected as a counterelectrode and is connected, for example, to earth, an arc or spark can ignite between the accumulated soot and the combustion electrode in the deep-bed filter cartridge, in which case the separated Soot particles can form bridges up to the pure gas withdrawal pipe. Surprisingly, the arc or 1' flower ignites the soot, which is combusted by the oxygen in the exhaust gas or the supplied air, with the arc or spark assisting the combustion after ignition and repeatedly ignite. In this way, a very complete regeneration takes place. The arrangement and connections can be as follows: i.e., when a predetermined amount of soot is collected in the deep bed filter cartridge, the soot combustion electrode will automatically ignite. It is assumed that the potential state changes due to accumulation.

る。However, the reproduction may also take place according to a temporal program. It is advantageous to carry out the regeneration already before a relatively small amount of soot has accumulated on the deep-bed filter cartridge. The combustion voltage is designed to provide ignition and combustion assistance with reliable function as described above. For example 50-100
Combustion voltage sources can be used which produce voltages of 0 V, in particular 80 to 160 1(). The oxygen required for soot combustion is extracted from the exhaust gas to be purified. Regeneration of the device according to the invention can therefore take place during normal operation of the device for separating soot from the exhaust gas stream of an internal combustion engine.
