Definitions
- the invention relates to a central discharge pipe for an inner-tube smoldering drum for waste which can be rotated about its longitudinal axis. It also relates to a pyrolysis device with a carbonization drum for waste which can be rotated about its longitudinal axis, in the interior of which a larger number of heating tubes are arranged, and with a discharge tube for discharging pyrolysis residue and carbonization gas from a central outlet opening of the carbonization drum.
- the so-called smoldering process has become known in the field of waste disposal.
- the method and a plant for thermal waste disposal operating according to it are described, for example, in EP-A-0 302 310 and in DE-A-38 30 153.
- the essential components of the plant for thermal waste disposal using the smoldering-firing process include a smoldering chamber (pyrolysis reactor) and a high-temperature combustion chamber.
- the smoldering chamber converts the waste that is fed in via a waste transport device into smoldering gas and pyrolysis residues.
- the carbonization gas and the pyrolysis residue are fed to the burner of the high-temperature combustion chamber after suitable processing.
- High-temperature combustion chamber creates molten slag, which is removed via a fume hood and which, after cooling, is in a glass-like form.
- the resulting flue gas is fed to a chimney as an outlet via a flue gas line.
- a heat recovery steam generator as cooling device, a dust filter system and a flue gas cleaning system are installed in this flue gas line.
- a smoldering chamber pyrolysis reactor
- a rotating, relatively long smoldering drum is generally used, which has a large number of parallel heating pipes on the inside, on which the waste is largely heated in the absence of air.
- the smoldering drum rotates about its longitudinal axis.
- the second object is achieved according to the invention by a pyrolysis device with a smoldering drum for waste which can be rotated about its longitudinal axis and in the interior of which a larger number of heating tubes are arranged, the heating tubes each having one end on a first end plate and the other Are attached to a second end plate, the first end plate having a central inlet opening for waste, and with a discharge pipe for discharging pyrolysis residue and carbonization gas from a central outlet opening of the carbonization drum, the discharge pipe being attached to the second end plate and around it Longitudinal axis is rotatable, and a lifting blade for conveying the pyrolysis residue is provided at the entrance of the discharge tube in the direction of the central exit opening.
- FIG. 3 shows a section through the region of the end plate on the outlet side in the plane III-III of FIG. 2;
- the lifting vane 33 can comprise a channel 45 extending parallel to the end plate 30 of the carbonizing drum 8 and a deflector 47 arranged thereon in the region of the entrance 17z and arranged at an angle to the end plate 30.
- the deflector 47 is designed in such a way that it conveys the solid material f fed from the channel 45 in the direction of the entrance 17z.

Abstract
Un tambour de carbonisation (8) pour déchets (A), qui tourne autour de son axe longitudinal (10), contient une pluralité de tubes chauffants (12) disposés dans son espace intérieur (13). Ces tubes chauffants (12) sont fixés par une de leurs extrémités à une première plaque de fond (28) et par l'autre extrémité à une seconde plaque de fond (30). Les résidus de pyrolyse (f) et les gaz de carbonisation produits par les déchets (A) lors du chauffage par les tubes chauffants (12) sont évacués par l'intermédiaire d'un tuyau d'évacuation (17) qui tourne conjointement avec le tambour de carbonisation (8). Afin que les produits solides (f) soient acheminés sans générer d'obstructions et afin d'éviter la chute répétée de gros morceaux pesants provenant des produits solides (f) dans la zone de sortie, il est prévu selon l'invention de fixer une pelle collectrice (33) à l'entrée (17z) du tuyau d'évacuation (17). Pendant la rotation du tambour (8), la pelle collectrice (33) entraîne les résidus de pyrolyse (f) et les achemine dans l'entrée (17z) du tuyau d'évacuation (17).
