Den Gegenstand vorliegender Erfindung bildet eine Vorrichtung zum kontinuierlichen Verkohlen von Holzabfällen, Torf und dergl. in Rohren unter gleichzeitiger Gewinnung der beim Verkohlen entstehenden Destillationsprodukte. Das wesentlichste Merkmal der vorliegenden Erfindung besteht darin, daß die über den eigentlichen Verkohlungszylindern angebrachten Füllzylinder abwechselnd mit einem Lufterhitzungsrohr und dem Schornstein oder mit den Verkohlungszylindern in Verbindung gebracht werden.The subject of the present invention is a device for continuous charring of wood waste, peat and the like. In pipes with simultaneous extraction of the distillation products formed during charring. The most essential feature of the present Invention is that the attached over the actual charring cylinders Filling cylinders alternating with an air heating pipe and the chimney or with the charring cylinders in connection to be brought.

Die Verkohlungsvorrichtung besteht im wesentlichen aus einer Anzahl, z. B. vier in einem Heizraum α eingeschlossener senkrecht stehender Rohre b, an deren oberen offenen Enden sich eine gleiche Anzahl von Füllrohren c zur Be-Schickung des Ofens anschließen, während die unteren Enden der Rohre abnehmbare Auffangbehälter d tragen und durch Schieber abgeschlossen ' werden können. Die Heizgase treten bei f in den Heizraum ein (Fig. 1 und 2) und umspülen die Rohre b sowie ein zwischen den letzteren angeordnetes Heizrohr g, in welches durch das Rohr h Luft eingesaugt wird (Fig. ι und 3). An seinem oberen Ende ist das Heizrohr g durch die Rohre i mit den Füllrphren c verbunden, während die letzteren mit dem vom Heizraum α aufsteigenden Schornstein k durch die Rohre I in Verbindung stehen.The charring device consists essentially of a number, e.g. B. four vertical tubes b enclosed in a boiler room α , at the upper open ends of which an equal number of filling tubes c connect to loading the furnace, while the lower ends of the tubes carry removable receptacles d and can be closed by slides . The heating gases enter the boiler room at f (FIGS. 1 and 2) and wash around the tubes b and a heating tube g arranged between the latter, into which air is sucked through the tube h (FIGS. 1 and 3). At its upper end, the heating pipe g is connected through the pipes i to the filling pipes c , while the latter are in connection with the chimney k rising from the heating room α through the pipes I.

Damit die Füllrohre c je nach Erfordernis mit dem Heizrohr g oder den Verkohlungs-Zylindern b in Verbindung gebracht werden können, sind sie drehbar um den in der Mitte des Ofens befindlichen Schornstein k angeordnet, indem sie mit ihren unteren Enden in senkrechten Kanälen η eines Drehschiebers m befestigt sind. Diese Kanäle sind, wie Fig. 5 zeigt, dem Querschnitt der Rohre entsprechend kreisförmig, besitzen jedoch nach dem Schornstein zu eine Erweiterung, so daß sie bei entsprechender Einstellung des Schiebers über die Kanäle i greifen. Die Kanäle i und die Verkohlungszylinder b sind durch die feststehende Platte ρ hindurchgeführt (Fig. 4 und 6). Wird der Schieber m mit den Füllrohren c so gedreht, daß diese mit den Verkohlungszylindern b kommunizieren, so werden die letzteren mit dem Verkohlungsgut beschickt. Während dieses Vorganges kann erhitzte Luft aus dem Heizrohr g in die Rohre c nicht eintreten, da die Öffnungen der an der unter dem Schieber liegenden Platte ρ befestigten und versetzt zu den Kanälen η liegenden Rohre i von der unteren Fläche des Schiebers verdeckt sind. Wird dagegen der Schieber m so gedreht, daß eine Verbindung zwischen b und c nicht mehr vorhanden ist, so gelangen die Kanäle η im Schieber m über die Öffnungen der Rohre i, so daß nunmehr heiße Luft von g nach den Rohren c übertreten und so das in letzteren befindliche Verkohlungsgut vorgetrocknet werden kann. An dem oberen Ende sind die Rohre c durch eine z. B. am Schornstein k befestigteSo that the filling pipes c can be brought into connection with the heating pipe g or the charring cylinders b , as required, they are rotatably arranged around the chimney k located in the middle of the furnace by placing their lower ends in vertical channels η of a rotary valve m are attached. As shown in FIG. 5, these channels are circular in accordance with the cross-section of the pipes, but have an enlargement after the chimney so that they reach over the channels i when the slide is adjusted accordingly. The channels i and the charring cylinder b are passed through the fixed plate ρ (Fig. 4 and 6). If the slide m with the filling tubes c is rotated so that these communicate with the charring cylinders b , the latter are charged with the charred material. During this process, heated air from the heating tube g cannot enter the tubes c because the openings of the tubes i attached to the plate ρ below the slide and offset from the channels η are covered by the lower surface of the slide. If, on the other hand, the slide m is turned so that there is no longer any connection between b and c , the channels η in the slide m pass through the openings of the tubes i, so that hot air now passes from g to the tubes c and so that charred material located in the latter can be predried. At the upper end, the tubes c are through a z. B. attached to the chimney k

Claims

Plate q covered, in which the openings for the pipes / are provided in a corresponding manner. The operation of the device is as follows: After the filling tubes c have been charged with the charred material through the side openings which can be closed by means of flap or slide r, air heated by the heating tube g is passed through them so that the material is predried accordingly. After pre-drying has taken place, the filling pipes c are brought over the charring pipes b by turning the rotary valve, so that the charring material falls into the charring pipes b and is charred there. As soon as the filling pipes are emptied, they are turned so far that their lower openings are covered by the full surface of the underlying plate ρ, while the pipes i communicate with the filling pipes and the chimney through the channels η and the pipes /. The filling tubes are now being loaded again and the process begins again. The product, which has been fully carbonized in the tubes b, is drained into the collecting container d after the slide e is opened and the slide is then closed again, while the distillation products are diverted through the tubes 0 connected to the tubes b and collected at a suitable point. Instead of rotating the filling tubes c with the rotary slide valve, they can also be stationary and only the slide m alone can be rotatably mounted. In this case, as Fig. 6 shows in side view, the lower ends of the filling tubes in a special plate s, which is similar to the plate ρ, fixed and provided in the side walls of the channels η of the slide m openings t through which the hot Air can get into the filling tubes c after entering the channels.
