    The invention relates to a tubular reactor for the thermal treatment of biomass with a rotating reactor space.
    Such reactors are also known as heated drum reactors. In the thermal treatment of biomass, e.g. Torrefication, in addition to the control and control of the process temperature for a uniform treatment and a control of the residence time in the tubular reactor is required. The residence time distribution should be as narrow as possible to achieve a product that is as uniform as possible. In known drum reactors, however, the residence time spectrum is very wide depending on the length and speed.
    The aim of the invention is therefore to provide a drum or tubular reactor which produces as uniform a product as possible.
    This is done according to the invention in that the reactor space is divided into zones by annular plates. Through these zones, the particles are retained in a certain area and mixed there, i. there is a homogenization of the treated particles. Only when the inside diameter of the sheet has reached can material (particles) be discharged into the next chamber or at the end.
    An advantageous development of the invention is characterized in that a delivery tool is attached to at least one plate, wherein the delivery tool can be mechanically adjustable. As a result, the material is uniformly promoted as a function of the reactor speed in the next chamber and thus evened out the residence time of all particles in the chamber.
    If at least on a sheet conveying tools for different directions of rotation provided so promote this material or they do not promote material, depending on the direction of rotation. Thus, after a change of direction accelerated emptying of the reactor is possible. It thus caking and / or overheating of the particles are avoided when stopping the reactor.
    A favorable development of the invention is characterized in that a delivery spiral is provided on the reactor inner drum shell. By such a conveyor spiral, preferably with a low height, a complete emptying of the reactor is possible. When rotating in the opposite 1
    2599 AT
    Direction of rotation during normal operation, this spiral acts for additional mixing within a zone.
    A favorable embodiment of the invention is characterized in that in the reactor space in the longitudinal (axis) direction extending heating tubes are provided, wherein the heating tubes can be arranged in a plurality of ring rows, preferably two rows of rings on the reactor inner drum shell. Through these tubes, through which a heating medium, e.g. Flue gas is passed, on the one hand, a uniform heating and on the other hand, a good mixing of ;; Particles reached. * *
    If the rotating reactor space is surrounded by a reactor outer drum and an annular gap is provided between the rotating reactor space and the reactor outer drum, the reactor outer drum can rotate with the reactor space, thus allowing even better heating of the particles with a large transfer area.
    The invention will now be described by way of example with reference to the drawings, in which Fig. 1 is a 3-D view of a tubular reactor according to the invention,
    Fig. 2 is a schematic representation of a tubular reactor according to the invention and
    Fig. 3 shows a section along the line III-III in Fig. 2 represents.
    In Fig. 1, an inventive tube reactor is shown. This is designed as an indirectly heated drum reactor 1, The biomass to be treated, for. Wood chips, is fed via a Eingußflansch 2 a heated feed screw 3 and from this in the rotating reactor space (not visible here). The heating medium, in this case flue gas, is introduced at a temperature of about 360-450 ° C. via the connection 4 into the reactor space and between the reactor space and the reactor outer drum 6. To seal against atmosphere are used before and after the reactor or cooling screw Zellrad sluice. 2
    2599 AT
    The cooled heating medium, in this case flue gas, then exits the drum reactor 1 at a temperature of about 280-300 ° C. via the connection 7. The gas generated by the thermal treatment exits at the nozzle 8. If the reactor is used for torrefaction, the torrefaction gas emerges here.
    Fig. 2 shows schematically the construction of the tubular reactor according to the invention by means of which the mode of operation is to be described. The reactor chamber 9 of the drum reactor 1 is divided by annular zone plates 10 into several zones .... in order to keep the axial mixing low. In the reactor chamber 9 is ;;; The input material is supplied with heat via the reactor internal drum * ··· ··· 11 heated by flue gas and the heating tubes heated by flue gas. The process temperature is approx. 280 - 300 ° C. The individual zone plates ····· 10 are equipped with at least one conveying tool 13 per zone plate 10. The·..·. Delivery tools 13 promote depending on the reactor speed and the *
    Execution more or less of material on the zone plates 10 in the direction of reactor outlet 15. The speed is about 8 to 20 U / min.
    The conveying tools 13 are designed in a special way to promote depending on the direction of rotation material or to promote any material. For this purpose, in addition, preferably several conveying tools 13 'are mounted, which promote material only in the opposite direction of rotation. This accelerated emptying of the reactor is possible after a change of direction and it can lead to no caking and no material overheating. This also prevents a fire from developing.
    In addition to the conveying tools 13, 13 ', a conveyor spiral 14 with a small height, which allows the complete emptying of the reactor in one direction of rotation, is attached to the reactor inner drum shell 11. When rotated in the opposite direction of rotation, this spiral causes additional mixing within a zone. Within a zone, a certain degree of filling arises in accordance with the delivery rate of the conveying tools 13. The residence time of the material in the tubular reactor 1 is about 20 to 40 min.
    At the reactor outlet 15, a conical pipe section 16 is attached by which material is conveyed in the direction of cooling screw 17 regardless of the speed. 3
    2599 AT
    In the cooling screw 17 is sprayed through a nozzle system 18 which is composed of a plurality of nozzles, very dusty water on the hot product. The amount of water is controlled by switching on and off of individual nozzles. The reference variable used is a temperature measurement on the 5 screw jacket. The resulting water vapor is over the
    Terminal 8 deducted together with the Torrefikationsgas or via an additional terminal 19. •
    Fig. 3 shows a section through Fig. 2 along the line III-III in the direction of the reactor inlet. It can be seen the zone plate 10 with the heating tubes 12, the '' 10 are arranged here for example in two rows, but also one or more
    Rows can be. Between the reactor inner drum shell 11 and the; Reactor outer drum 6 is an annular space 20 through which the flue gas is performed by way of example here. This heats the reactor inner drum shell 11, thus increasing the heat transfer area. Furthermore, one can see the conveying tool 13, which conveys the material in the operating direction of rotation 21 in the direction of the reactor outlet 15. However, it is also possible to provide a plurality of such delivery tools. For rapid emptying the direction of rotation is reversed and the conveying tools 13 '(shown here three) promote the material quickly and completely out of the respective zone 20. It can also be provided here more delivery tools, but the number of delivery tools 13 'for emptying always (substantially) must be greater than the delivery tools 13 for residence time control in normal operation. 4
