Abstract:
A method for thermal disposal of waste, comprising the steps of: receiving and amassing waste to be disposed of in a receiving and amassing section (2) of a disposal system (1); transferring said waste to be disposed of from said receiving and amassing section (2) into a burning section (3) for burning said waste; incinerating said waste in said burning section (3), said amassing including storing at least perishable waste at low temperature in container means (10) having means for controlling and lowering internal temperature.
Abstract:
Ein Brenner (40) zur Verbrennung von Müll in Müllverbrennungsanlagen besteht aus einem Brennertopf (46) aus hochtemperaturfestem Material und einem pilzförmigen Brennerkopf (41). Ein Müllförderkanal (36) trott von unten in den Brenner (40) ein und endet am pilzförmigen Brennerkopf (41), dessen obere Seite kegelförmig gestaltet ist. Der Brennertopf (46) bildet mit dem Brennerkopf (41) einen ringförmigen Raum für ein Schlackenbad (49).

Abstract:
Der Hausmüll (1) wird auf eine für den Prozeß geeignete Größe vorgeschreddert (2), in einer cryogenen Stufe (3) mit kaltem Stickstoff (4), der in einer Luftzerlegungsanlage (5) aus Luft (8) gewonnen wird, versprödet und vorzerkleinert (6). Anschließend erfolgt eine Abscheidung der magnetischen Metallanteile (7). In einer weiteren Stufe (9) wird der Hausmüll auf eine für den Verbrennungsprozeß geeigneten Korngröße aufgemahlen und für den Verbrennungsprozeß aufbereitet. Über ein geeignetes Dosiersystem wird der Brennstaub dem Brenner zugeführt und in einer Schmelzkammer (10) unter Zugabe von reinem Sauerstoff (11) aus der Luftzerlegungsanlage (5) oder einem Sauerstoff-/Luftgemisch verbrannt. Die Schmelzkammer (10) kann mit einer ungekühlten Ausmauerung, einer gekühlten Ausmauerung oder einer gasdicht verschweißten Rohrwand versehen werden. Die schmelzflüssige Schlacke (12) wird abgekühlt und aus dem System ausgeschleust. Die Abwärme der heißen Rauchgase wird in einem Abhitzesystem (13) zur Dampferzeugung (14) genutzt.
Abstract:
A method for processing waste containing a large amount of water and a method for processing leachate from industrial wastes. A waste processing method comprises maintaining reduced pressure in a dryer (1) equipped with a stirring means (3) feeding waste containing a large amount of water to the dryer, stirring the waste while blowing refrigerated air at - 20°C ± 5°C to the dryer, and drying the frozen moisture portion of the wastes by sublimation. Air heated at 80°C ± 10°C can be used instead of refrigerated air to dry water of the wastes by evaporation. A method for processing leachate comprises pooling leachate industrial wastes and burned ashes, and utilizing the leachate to absorb wet-type toxic gas, thereby confining the leachate within the waste treatment plant. This makes it possible to process waste containing a large amount of water, which has been a problem in incineration by conventional methods, by using the potential heat of the waste gas from the incinerator to refrigerate or heat the air for the dryer and to prevent environmental contamination because leachate is confined in the waste treatment plant.
