Description

Technical area

The present invention describes a stirrer as part of a stirring and conveying device for storage in a Karbonisierungsbehälter, which is drivable from outside the Karbonisierungsbehälters, and the use of a stirrer as part of a stirring and conveying device for storage in a Karbonisierungsbehälter, which of is drivable outside the Karbonisierungsbehälters.

State of the art

Under hydrothermal carbonization (HTC) or wet charring is understood to mean the refining of wet or moist biomass in aqueous mostly acidic environment at elevated temperatures by 200 ° C and elevated pressures of more than 10 bar in a pressure-tight Karbonisierungsbehälter. In order to start the hydrothermal carbonization, the biomass, water and catalytically active substances must first be heated to the elevated temperature at the beginning. Subsequently, the reactants react to intermediates and ultimately to Karbonisierungsprodukten, which are in the form of a biochar or brown coal suspension, which contains not only coal but also process water and residual substances. By hydrothermal carbonation, the natural process of coal formation is technically reproduced within a few hours and above all the high carbon efficiency distinguishes the HTC.

In the present application is understood as a fermentable biomass and thus as part of the starting materials, which can be processed by the hydrothermal carbonization to coal, preferably a mixture of sewage sludge and green waste. In the described reactor, however, other biogenic residues, in particular renewable raw materials, such as wood chips, green cuttings from landscape care, plants, straw, silage, and organic residues from agriculture and forestry and the food industry and waste management, as well as peat, lignite, Paper sludge, to be refined into masses with a high proportion of coal.

Since the described reaction of a highly viscous and / or solid-laden process medium of a biomass added liquid and thus a solid-liquid mixture in reaction times of a few hours under high pressure and elevated temperatures, specially adapted reactors and stirring and conveying devices are required ,

In order to achieve a thorough mixing of the solid-liquid mixture and to convey the process medium controlled by the Karbonisierungsbehälter, in the Karbonisierungsbehälter a suitable agitator may be arranged, which is part of the stirring and conveying device.

EP 1 970 431 discloses a horizontal carbonization container, in the interior of which a screw conveyor is arranged, by means of which the contents are conveyed from an inlet side to an outlet side of the carbonation container. By operating the screw conveyor from outside the carbonation container, the pressure in the interior of the Karbonisierungsbehälters can be maintained throughout the process. Intermediate and end products that accumulate on the carbonation vessel wall can be transported away and the contents are constantly mixed, which optimizes the reaction. The contents can be distributed in the interior of the Karbonisierungsbehälters and thus in the space within the screw conveyor, whereby a mixture of reactants and products takes place to a certain extent.

The screw conveyor may have continuous turns, which educts and products mix as little as possible. By designing the conveying direction along a cylinder axis in the cylindrical Karbonisierungsbehälter from an inlet to an outlet mixing of fresh biomass with different levels of carbonized biomass is largely prevented. Since in the course of the passage of the biomass through the Karbonisierungsbehälter different reaction stages are passed through with different degrees of heat generation, an inhomogeneous heating of the interior of the Karbonisierungsbehälters and the screw conveyor is given. This inhomogeneous and local heating is problematic for the material of the screw conveyor and its function and can lead to increased wear.

In order to reduce the thermal and mechanical stress on the conveyor, a conveyor in the form of a screw conveyor with a plurality of screw flights is used in DE10 2009 007 302, wherein at least one screw spiral is additionally provided with openings. This allows mixing of the starting materials and products take place, and thus local heating can be mitigated. Mixing of the starting materials and products, however, represents a disadvantageous solution since the carbonation process is disturbed. Due to the design of a conveyor with at least one double helix, the space in the interior of the process medium is limited. The process medium is highly compressed in the interior of the carbonation container, wherein the active surface for a heat exchange of heat from the process medium to the wall of the Karbonisierungsbehälters is reduced. Since the conveyor fulfills no or only a small thermally conductive function, the heat-conducting properties of such conveyors and thus the heat exchange of the process medium are deteriorated.

Presentation of the invention

The present invention has for its object to provide a stirrer as part of a stirring and conveying device for a process medium in a Karbonisierungsbehälter, which achieves improved promotion with low direct mixing of educts and products and an optimized heat exchange of the process medium with the Carbonation and different reaction stages of the process medium allowed.

This object is achieved with a stirring and conveying device comprising a hollow cylindrical tubular agitator. The agitator is wave-free formed by dispensing with a central shaft and configured with a plurality of conveyor blades, which allow a promotion of the process medium in different directions at different distances to the Karbonisierungsbehältermantel.

In order to increase the delivery even further, a deflection device for deflecting the process medium in the carbonation can be arranged as an addition of the stirring and conveying device.

description

The present application describes a hydrothermal Karbonisierungsanlage, comprising a multi-part reactor 1 in which the hydrothermal carbonization of a highly viscous and / or solids-laden process medium is efficient and continuous feasible. The highly viscous and / or solid-laden process medium comprises filling material which consists of raw biomass of various composition and consistency, process water and additives, e.g. Catalysts exists. Due to its composition, the process medium is present as a suspension or as sludge, with liquid fractions being mixed with solids. The content of the contents of the process medium is also considered to be a starting material, since it forms a solid-liquid mixture which, in the course of the hydrothermal carbonization, is converted into carbonization products comprising charred biomass. The carbonation products form a charred portion of the process medium, which has a similar solid-liquid consistency to the starting materials, with the solid components being at best fully converted to brown coal.

The starting materials are introduced into the reactor 1 of the Karbonisierungsanlage, under high pressure and elevated temperature, as known from the basics of hydrothermal carbonization, charred after the process as Karbonisierungsprodukte discharged from the reactor 1. The introduction and removal or the supply and discharge of educts and Karbonisierungsprodukte can take place in portions during operation of the Karbonisierungsverfahrens, the Karbonisierungsprozess is not significantly disturbed and is not interrupted and thus can proceed quasi-continuously.

The reactor 1 comprises an outer container 10, which is rigid and serves as a pressure vessel. The outer container 10 is rotatably mounted on a reactor storage device 2 about the outer container longitudinal axis La. On two racks 20 pivot bearings 21 are arranged so that the outer container 10 is controlled by at least one rotary drive 22 rotatable. As a rotary drive 22, for example, suitably dimensioned electric motors. This rotatable storage of the reactor 1 is used to support the Karbonisierungsprozesses, but is not mandatory.

In the embodiment shown here, the outer container 10 has an outer container shell 100 with a cylindrical centerpiece 1003, which is closed off by a base base 1001 by a base flange 1002 releasably lockable and liquid-tight and pressure-tight. From the base bottom 1001 side, the process medium is supplied and discharged. On the base bottom 1001 opposite side of the outer container shell 100, the cylindrical centerpiece 1003 is closed by a curved lid bottom 1005 executed by means of Deckelbodenflansch 1004 releasably liquid and pressure-tight. The outer container 10 is stored lying, wherein the outer container longitudinal axis La extends approximately horizontally to the level of the ground at the site. The outer container 10 is detachably closable and thus completed the process of hydrothermal carbonization through the outer container 10 in the reactor 1 from the environment.

The outer container 10 is rigid for stability reasons and preferably made of steel, wherein the wall thicknesses are chosen so that even fluid pressures of several bar can be safely formed within the outer container 10, which the outer container 10 can withstand. Depending on the planned plant size and the amount of educts to be converted, the size of the outer container interior 103 is selected.

In the base bottom 1001 a filling passage 104 and an output passage 105 is arranged completely crossing, whereby access to the outer container 10 from the outside with otherwise closed outer container 10 is made possible. In Fig. 1b, a stirrer drive means 132 is shown, which will be explained in connection with a stirring and conveying device.

Fig. 2 shows a reactor 1 with a possible embodiment of a connected feed and discharge device 4. On the reactor storage device 2 has been omitted in this perspective view. Shown here, the embodiment of the supply and discharge device 4, a feed cylinder 40 and a removal cylinder 41, which are releasably operatively connected respectively to the filling passage 104 and the output passage 105.

For maintenance purposes, the supply and discharge device 4 can be completely separated from the reactor 1 and be connected in the operating state according to liquid and pressure-tight with the reactor 1. The supply and discharge device 4 is releasably secured by flange on the reactor 1. A device bearing 42 is designed such that the supply and discharge device 4 is mounted relative to the reactor 1 aligned. Since the reactor 1 explained here is preferably rotated around the outer container longitudinal axis La during the course of the carbonization process, the device bearing 42 is designed such that the supply and discharge device 4 can be rotated during rotation of the reactor 1 about the outer container longitudinal axis La with the feed and discharge device 4 connected , To facilitate rotation, the device bearing 42 is height adjustable. A force regulator can optimally adjust the height of the device bearing 42 for rotation to be achievable.

So that the process medium in the form of educts can be fed and discharged in the form of the carbonization products, drive means 43 are provided on the supply and discharge device 4. The process medium can thereby be transferred in a controlled manner with a control, not shown.

As shown in the horizontal section through the reactor 1 according to FIG. 4, within the outer container 10, the mentioned Karbonisierungsbehälter 11 is stored completely embedded, wherein the Karbonisierungsbehälterlängsachse Lp coincides with the outer container longitudinal axis La together. This Karbonisierungsbehälter 11 is connected to the filling channel 1141 and the output channel 1142 fixed to the base bottom 1001 of the outer container 10 and thus immovably stored in the outer container shell 100 relative to the outer container 10.

The Karbonisierungsbehälter 11 has a Karbonisierungsbehältermantel 111 which is completely surrounded or lapped in the operating state of a fluid 3. In the interior of the Karbonisierungsbehälters 11 is in the operating state, the process medium 5 in the different states. The carbonizing container 11 includes a central shell portion which is disposed between a lid part 1101 and a bottom part 1105. The central shell portion is configured cylindrically shaped and the cover part 1101 by means of cover flange 1102 and the bottom part 1105 releasably secured by means of bottom flange 1106 on the central shell portion. The entire Karbonisierungsbehälter 11 is pressurized in the operating state with the process medium 5 under pressure and is carried out corresponding liquid and pressure-tight.

Subsequently, an output channel 1142 is connected to the bottom part 1105, which leads out of the interior of the Karbonisierungsbehälters 11. After installing the carbonation container 11 in the outer container 10, the discharge channel 1142 is arranged so as to be guided by the discharge passage 105 of the base tray 1001.

As shown in Fig. 5a, a filling channel 1141 is connected to the bottom part 1105, which is correspondingly feasible through the filling passage 104 in the base bottom 1001 of the outer container 10. The dispensing channel 1142 and the filling channel 1141 can be fastened by the base base 1001 so as to be unsolvable by means of a cohesive welded connection or detachable by means of flange connections to the base plate 1001. By fastening flanges 115 integrally formed on the filling channel 1141 and the outlet channel 1142, the channels 1141, 1142 can be connected to the supply and discharge device 4, which has been omitted in FIGS. 5a and 5b for the sake of clarity.

In the operating state, the process medium 5 is filled through the filling channel 1141 in the interior of the Karbonisierungsbehälters 11 and discharged after a dwell or reaction time through the output channel 1142 from the Karbonisierungsbehälter 11. Accordingly, filling and dispensing channel 1141, 1142 are opened only temporarily controlled during operation in order to influence the exothermic reaction of the hydrothermal carbonization only briefly. Thus, the internal pressure and the temperature in the carbonation container 10 is only briefly disturbed.

While in the carbonation 11, the hydrothermal carbonization proceeds under elevated temperature and elevated pressure, the fluid surrounds 3, which is in particular a thermal oil, the Karbonisierungsbehälter 11 within the closed outer container shell 100th

The thermal oil 3 is used in the hydrothermal carbonization here, inter alia, as a heat transfer fluid. A supply nozzle 106 arranged on the outer container 10 is used for filling and pressurizing the outer container interior 103 with the fluid 3. At the supply nozzle 106, spidery-like tubes 109 are provided in the outer container interior 103 for the flow guidance of the thermal oil 3. By means of vent pipe 108, the air can be discharged from the outer container interior 103 during filling. Thus externally heated thermal oil 3 can be supplied from a thermal oil tank, whereby the Karbonisierungsbehälter 11 can be brought to a temperature necessary for carbonization. Due to the temperature increase of the thermal oil 3, the exothermic reaction is started and maintained, since this takes place only from a minimum temperature. By measuring the temperature and the possibility of exchanging the fluid 3, the temperature in the carbonation container 11 can be controlled.

The thermal oil in the outer container 10 and the Karbonisierungsbehälter 11 form a heat exchanger. The high-viscosity solids-laden educts 5 and products 5 in the interior of the carbonation container 11 release their heat partly through the Karbonisierungsbehältermantel 110 during the hydrothermal carbonization to the surrounding thermal oil 3 from. The thermal oil 3 flows around the Karbonisierungsbehälter 11 and can absorb and release heat. If the Karbonisierungsbehälter 11 are cooled, according to excess heat energy can be used externally by means of thermal oil 3.

In order to ensure the passage of the process medium 5 through the interior of the Karbonisierungsbehälters 11 is a stirring and conveying device comprising an agitator 13, the interior at least partially arranged transversely. In operation, by means of agitator 13, a continuous mixing of the process medium 5, the educts and Karbonisierungsprodukte controlled from the outside take place. The agitator 13 also serves as a conveying device of the process medium 5. The agitator 13 can be designed in different ways. Agitator drive means 132 are provided to operate the agitator 13 from the outside in operation. By a drive bushing 107 in the outer container 10 and a transverse drive device 119 which leads to the agitator 13 in the Karbonisierungsbehälter 11, the agitator 13 is driven driven. Since the Karbonisierungsbehälter 11 is formed of several parts, the agitator 13 can be easily inserted into the Karbonisierungsbehälter 11, rotatably mounted there by means of agitator bearing 133 and actuated controlled from outside the reactor 1. The agitator 13 is here equipped with a friction wheel, which is shown in Fig. 5beingekreist. At the agitator 13 leaves are arranged as baffles and / or to support the axial promotion.

The Karbonisierungsbehälter 11 and the agitator 13 therein are designed so that the process medium 5, which comprises biomass in the form of sewage sludge and green waste, during the Karbonisierungsprozesses can be conveyed. The biomass is comminuted externally before being fed into the reactor, but solids with a maximum piece size of 2.5 cm × 2.5 cm × 2.5 cm remain as part of the process medium 5. By this solid loading 13 special requirements are placed on the Karbonisierungsbehälter 11 and the agitator.

Characterized in that the outer container 10 and the Karbonisierungsbehälter 11 are each formed in several parts, a simple assembly of the reactor 1 and thus the entire system at the site is possible. Above all, maintenance work can be carried out without great effort, since no manhole must be provided in order to have access to the containers 10, 11.

All walls and components that come into direct contact with the process medium 5 are made of acid-resistant material. Here these parts are made of stainless steel.

The stirring and conveying device is formed by the agitator 13. The agitator 13 is designed with a Rührwerkwand tubular as a hollow cylindrical body, which is rotatable about a conveyor longitudinal axis LF within the Karbonisierungsbehälters 11 can be arranged. The agitator wall forms a completely closed cylindrical surface. For the sake of clarity, the carbonation container in FIG. 6 has been omitted. In contrast to agitators of the prior art, the agitator 13 is formed without a centric shaft and forms a stable hollow cylindrical body whose size is adapted to the interior of the Karbonisierungsbehälters 11, so that the agitator wall is at least approximately parallel to the Karbonisierungsbehältermantel 110.

When installed, a base portion 136 of the bottom part 1105 and a deflection 137 faces the cover part 1101 of the Karbonisierungsbehälters 11. The base portion 136 has a base portion edge 1360 and the deflection portion 137 a Umlenkabschnittskante 1370. In the region of these edges 1360, 1370, the below-described mounting of the agitator 13 is configured.

The hollow cylindrical body of the agitator 13 has an inner surface 131 on which a plurality of inner leaves 1311 is arranged. The inner blades 1311 are arranged distributed on the inner surface 131 along the inner periphery of the agitator wall and oriented such that process medium 5 in the direction of the deflection portion 137 in a first conveying direction Y is conveyed. The inner leaves 1311 are arranged protruding at least approximately radially to the longitudinal axis LF.

The space in which the inner leaves 1311 are arranged projecting from the agitator wall to the center is referred to as inner delivery chamber 134. This inner delivery chamber 134 is designed concentrically with respect to the delivery longitudinal axis LF, and through the inner leaves 1311, a drive in the direction of the deflection section 137 and thorough mixing of the solid-liquid mixture during the rotation of the agitator 13 can be achieved. The process medium 5 is conveyed along the inner surface 131 in the first conveying direction Y as indicated by the arrows in the direction of the deflection section 137.

On an outer surface 130 of the agitator 13, a plurality of outer leaves 1301 along the circumference of the outer surface 130 is uniformly distributed and arranged radially projecting. These outer leaves 1301 are aligned so that they allow a promotion of the process medium 5 in the direction of the base portion 136 parallel to the longitudinal axis LF and thus promoting axially. This second conveying direction is indicated by the arrow X. When the agitator 13 is in the carbonation vessel 11, a concentric outer delivery chamber 135 is formed between the outer surface 130 of the agitator wall and the inner surface of the carbonation vessel shell 110, which can be seen in FIG. By means of this outer delivery chamber 135, the process medium 5 can be conveyed concentrically in the direction of the base section 136 and delivery channel 1142 in the bottom flange 1106. The process medium 5 is conveyed on the outer surface 130 with contact to the inner surface of the Karbonisierungsbehältermantels 110 and the outer surface 130 in the X direction. The outer leaves 1301 perform a propulsion function and stir and mix the solid-liquid mixture during the rotation of the agitator 13th

By means disposed in the Karbonisierungsbehälter 11 agitator 13, the process medium 5 is moved by inlet through the filling passage 104 through the inner delivery chamber 134 concentrically in the direction of deflection 137 in the first conveying direction Y. The process medium 5, as it passes through the internal delivery chamber 134, is heated to suitable temperatures of 200 ° C and more, thereby starting and maintaining the exothermic charring reaction. The heat transfer takes place through the agitator wall.

After a single crossing of the Karbonisierungsbehälterlänge with mixing in the inner delivery chamber 134, the process medium in the region of the deflection 137 is deflected by 180 °. At this position, the process medium 5 is particularly strongly heated because the hydrothermal carbonization is already advanced. On the way between the base section 136 and the deflecting section 137, the process medium 5 reacts exothermically, wherein heat is continuously released depending on the reaction step. Since the temperature of the process medium 5 varies depending on the reaction stage, a temperature gradient is formed in the inner delivery chamber 134.

After the deflection, the process medium 5 is moved concentrically through the outer delivery chamber 135 in the direction of the base section 136 in the second conveying direction X. This deflection takes place because the orientations of the inner sheets 1311 and outer sheets 1301 are different and the process medium 5 in the cover part 1101 of the Karbonisierungsbehälters 11 is forced to Karbonisierungsbehältermantel 110. The particularly hot process medium 5 is moved along the outer surface 130 of the agitator 13 in contact with the Karbonisierungsbehältermantel 110 in the concentric outer delivery chamber 135, whereby the heat of reaction can be removed facilitated by a large surface. The process medium 5 also emits heat energy through the agitator wall to the process medium 5 in the inner delivery chamber 134. Since the agitator wall is made liquid-tight, only the heat and no process medium 5 is transferred from the outer to the inner delivery chamber 134.

The process medium 5 is finally moved back to the output passage 105 and can be removed later.

To additionally support the deflection, an additional deflecting device 117 is provided. In the figures, this deflection device 117 is shown as an inclined bottom plate 117 arranged on the cover part 1101. This inclined bottom plate 117 may be formed in the interior of the Karbonisierungsbehälters 11 or releasably secured. However, a deflection device 117 can also be designed differently either at the deflection section 137 of the agitator 13 or in the region of the cover part 1101 of the carbonization container 11. For example, a collar attached to the deflection section 137 or molded could be formed. The stirring and conveying device is then composed accordingly deflection device 117 and agitator 13.

The agitator 13 is rotatably mounted within the Karbonisierungsbehälters 11 about a conveyor longitudinal axis LF on a plurality of agitator bearings 133. In Fig. 8a, the Umlenkabschnittskante 1370 is mounted at a distance from the inner surface of the Karbonisierungsbehältermantels 110. In each case, a wheel pretensioned against the force of a spring 1331 is provided, which keeps the agitator 13 in the region of the deflection section 137 at a fixed distance from the carbonization container shell 110. There are six agitator bearings 133 along the circumference of the Umlenkabschnittskante 1370 is provided. Due to the spring-mounted bearing compensation of the agitator 13 during rotation to some extent achievable.

By means of agitator drive means 132, the agitator 13 from outside the Karbonisierungsbehälters 11 can be actuated. The agitator 13 is driven here by means of friction wheel drive, the details of which are enlarged in Fig. 8bdargestellt. From the agitator drive means 132, which may be configured as an electric motor and is arranged outside the carbonation container 11, a drive shaft 1320 leads into the carbonation container 11. On a compensating element 1321 a Reibradrolle 1322 is arranged, which is arranged rotatably on the outer surface 130 of the agitator 13. The friction wheel roller 1322 is held by a roller bearing 1323. The base portion edge 1360 of the agitator 13 rotatably supports in a base bearing 133, so that the hollow cylindrical body is rotatably supported by friction wheel drive about the axis LF. From the outside of the friction wheel is controlled without difficulty.

It would also be possible to use a gear drive for rotating the agitator 13.

By this design of the Karbonisierungsbehälters 11 with a deflection of the process medium 5 enabling stirring and conveying the length of the Karbonisierungsbehälters 11 can be kept low and the reactor 1 are kept correspondingly compact. The design of the stirring and conveying device comprising an agitator 13 with a thermally conductive agitator wall, heat within the Karbonisierungsbehälters 11 can be optimally transferred to the process medium 5 and discharged from this, so that the stirring and conveying additionally performs the task of a heat exchanger.

Is the Karbonisierungsbehälter 11 movable and configured variable in shape, wherein at least a portion of the Karbonisierungsbehältermantels 110 is configured in several parts, the parts are pressure and liquid-tightly separated from each other and defined reproducible relative to each other are movably mounted, so targeted the Karbonisierungsbehältercup volume is changeable and the internal pressure on the process medium 5 in the Karbonisierungsbehälter 11 is independent of the process temperature adjustable, then the stirrer 13 is carried out according to several parts and variable length. This is already shown in FIG. 6. The agitator wall of the hollow cylindrical agitator 13 is configured of two separable hollow cylindrical agitator walls, which are mutually displaceable.
