いる形式のものに関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a device for cleaning a fire-resistant filter for filtering exhaust gas from an internal combustion engine, and is operable regardless of the operating state of the internal combustion engine. The combustion chamber has a rotationally symmetrical design, the combustion chamber widening conically towards the opening and opening into the exhaust casing for receiving the filter; has a nozzle for fuel supply on the opposite end face and an inlet opening in the area of the conical jacket, through which combustion air is introduced under high pressure. Regarding formal matters.

ている。PRIOR ART In a cleaning device of the above-mentioned type, known from DE 175 1 024, a filter for collecting solid material components (soot or the like) from the exhaust gas is used in an internal combustion engine. They are arranged close together so that, at least during full-load operation of the internal combustion engine, the specific substance components are ignited by the temperature of the exhaust gas.

つてしまう。また過剰な全負荷運転はフイルタを
過度に熱負荷し、それによつて該フイルタの摩耗

なる。 However, a disadvantage of this known design is that its efficiency is sharply reduced if the internal combustion engine is operated only in the partial load range for a long time.
The contamination of the installed filter becomes such that sufficient cleaning cannot be achieved even during subsequent longer full-load operations. This makes it necessary to replace the filter early. Excessive full-load operation also places an excessive heat load on the filter, which causes it to wear more quickly and therefore has to be replaced sooner.

ことができる。 When the filter 3 becomes contaminated to the extent that it requires cleaning, the switch 25 is closed. The electromagnet for switch 24 closes this switch 24, thereby opening magnetic valve 16. Vane pump 17 starts and pumps air to mixing nozzle 9 and nozzle 1.
Send towards 0. The fuel is atomized in the mixing nozzle 9 and mixed with air. The additional air from the nozzle 10 is then passed on to the fuel-air mixture exiting the mixing nozzle 9 with swirling. This fuel/air mixture is then ignited by the igniter 11 and burned with a flame that uniformly heats the entire surface of the filter 3. Due to the excess air present in the cleaning device, the solid material components (mainly soot) collected in the filter 3 are combusted.
After the combustion of the solid material components collected on the filter has ended, the switch 25 is opened and the cleaning device is shut off again. By closing the magnetic valve 16, the fuel supply to the combustion chamber 6 is also interrupted. The filter 3 is again able to filter the exhaust gas stream (arrow 27) sufficiently in the exhaust device 2 without loss of efficiency.
