Definitions

  • the present invention relates to a device for processing a material mixture consisting of substitute fuel and impurities, which is sifted, crushed and dried in the device.
  • the substitute fuel also known as secondary fuel, includes in particular solid waste, which can be used together with conventional fuels, especially in cement, lime, lignite or industrial power plants as well as in waste incineration plants or as the sole fuel in substitute fuel power plants.
  • Solid waste for example, consisting of commercial waste and/or household waste, usually still contains impurities such as glass or metals after coarse shredding. It is therefore known to carry out separation after coarse shredding and, if necessary, to further shred the substitute fuel.
  • EN 10 2015 005 604 A1 A device according to the preamble of claim 1 is known.
  • the object of the present invention is therefore to provide a device with which it is possible both to separate the contaminants from the substitute fuel and to produce the substitute fuel with a different average size of the substitute fuel particles, whereby a higher degree of comminution and better drying of the material mixture can be achieved with the same height of the rotor mill.
  • a device for processing a material mixture consisting of substitute fuel and impurities comprising a vertically aligned central feed, a separating device arranged below the central feed, a rotor mill, wherein the rotor mill is arranged above the separating device and surrounds the central feed, and a flow device for generating an upwardly directed gas flow, wherein the material mixture can be introduced into the feed and, after being introduced into the feed, sinks to the separating device, wherein the impurities are at least partially separated from the material mixture in the separating device as an impurity fraction and the material mixture separated from the separated impurities rises with the gas flow to the rotor mill, wherein the rising material mixture is crushed in the rotor mill.
  • the rotor mill has several tools arranged vertically and offset from one another in the circumferential direction.
  • the material mixture can be introduced into the feeder via a funnel or another feeding device, for example, whereby the feeder is aligned vertically so that the material mixture introduced into the feeder sinks into the feeder.
  • the feeder is therefore hollow on the inside so that the material mixture can sink undisturbed.
  • the feeder can be formed by a pipe (hollow cylinder).
  • a separating device is arranged below the central feed, which comprises, for example, a rotatably driven spreading plate.
  • the separating device is designed in particular so that at least a large proportion of the Impurities can be separated (sifted) from the material mixture, whereby the separated impurities can be removed from the device in a suitable manner.
  • a flow device For separation/sifting, a flow device is provided by means of which an upwardly rising gas flow can be generated at least in the area of the separation device, in particular in the area of the spreading plate of the separation device, and the rotor mill.
  • the flow device has in particular at least one gas inlet, preferably arranged in the lower area of the device, and at least one outlet in the upper area of the rotor mill. Heated air can be used as the gas, for example.
  • the material mixture fed through the central feed is thrown from the spreading plate into a space surrounding the spreading plate, in which the gas flow rises, whereby the rising gas flow takes only the substitute fuel with it, and a large part of the impurities sink into the space surrounding the spreading plate.
  • the substitute fuel that is carried along is then dried with the gas flow.
  • the substitute fuel carried along by the gas flow (and any impurities that have not been separated) is fed with the gas flow to the rotor mill, which is arranged above the separating device (spreading plate).
  • the substitute fuel is crushed in the rotor mill by impact, shear and impact forces.
  • the rotor mill preferably has at least one rotationally driven tool that promotes the crushing of the substitute fuel.
  • the separating device (and in particular its spreading plate) and the tools of the rotor mill can be driven together to rotate (rotationally) about a vertically aligned axis.
  • the feed can also be driven to rotate at the same time.
  • the spreading plate can be connected in a rotationally fixed manner to the element limiting the feed (for example a pipe), with the at least one tool of the rotor mill preferably being attached to an outside of the element forming the central feed in its interior.
  • the drive is arranged in particular in the lower region of the device and can, for example, generate a rotational movement with 500 to 1000, preferably with 700 to 900 revolutions/min.
  • the invention also provides that the rotor mill (and in particular each stage of the rotor mill) has several, in particular more than 10, preferably more than 20 tools arranged vertically and offset from one another in the circumferential direction.
  • This arrangement of the tools, offset both in the circumferential direction and in the vertical direction, results in a longer residence time of the material mixture and thus more effective comminution of the material mixture, so that a higher degree of comminution can be achieved or the rotor mill can be realized with a lower height.
  • the longer residence time also results in better drying of the material mixture.
  • the rotor mill has a centrally arranged and rotationally driven hollow cylinder (which preferably also forms the central feed), on the outside of which the tools are attached, wherein the tools extend individually radially outwards from the outside of the hollow cylinder.
  • the tools are therefore in particular elongated elements that extend from the Hollow cylinders extend outwards.
  • the entire area between the outside of the hollow cylinder and a radially spaced boundary of the rotor mill can be flowed through by the rising material mixture, whereby an interaction with the tools can take place in the entire area.
  • a group of tools and/or most of the tools comprise flat wing elements that extend radially outwards.
  • the wing elements are attached directly or indirectly to the outside of the hollow cylinder and are significantly longer (at least three times, preferably at least five times) in the radial direction than their width.
  • the wing elements have a height that is less than their width, with the wing elements being at least twice, preferably four times as wide as they are high. It has been found that such wing-like elements enable particularly efficient comminution of the material mixture.
  • a further improvement in comminution is achieved according to the invention in that the wing elements are set at an angle to a horizontal plane.
  • the angle of attack is preferably 3° to 45°, particularly preferably 5° to 20° to the horizontal plane.
  • At least one tool or a plurality of tools comprises a plate-shaped impact element which is arranged at a radial end of the tool, wherein the plate-shaped impact element is in particular aligned vertically.
  • the plate-shaped impact element With such a plate-shaped impact element, the comminution efficiency can be further increased.
  • At least one tool comprises a scraper element that is arranged radially on the outside of the tool and is in contact with a wall of the rotor mill or the stage of the rotor mill that delimits the grinding chamber on the outside, wherein the wall can be formed, for example, by a grid arrangement that separates the grinding chamber from an annular space.
  • the scraper element can therefore prevent or solve the accumulation of particles of the material mixture on the inside of the wall.
  • the plate-shaped impact element or the scraping element can, for example, be attached to a radial end of the previously described wing element of the tool.
  • At least one tool is made of a wire which is attached to the outside of the hollow cylinder.
  • a wire is understood to be an element which extends longitudinally outwards from the hollow cylinder and whose width and height are approximately the same.
  • the wire preferably has a circular cross-sectional design.
  • a plurality (in particular more than 8, preferably more than 16) of tools are arranged in a lower region of the rotor mill or in a lower region of a stage of the rotor mill, while a plurality of tools comprising a wire are arranged in an upper region of the rotor mill or in an upper region of a stage of the rotor mill.
  • a group (more than 4) of tools can be arranged helically (i.e. on a screw line) offset from each other, whereby several groups of tools can be arranged one behind the other in the circumferential direction.
  • the rotor mill is designed in several stages, i.e. at least and preferably exactly two or three stages, optionally four stages, with at least one separating device (for example a sieve) being arranged between the stages of the rotor mill, with material mixture not retained by the separating device being further crushed in the following stage, with particles of the material mixture containing mainly substitute fuel with a particle size larger than that specified by the separating device being retained in the previous stage, while particles of the material mixture with a smaller size can reach the following stage.
  • the material mixture is then further crushed in the following stage of the rotor mill.
  • the multi-stage nature of the rotor mill means that substitute fuel with different average particle sizes can be provided with one device.
  • the fraction of the material mixture withdrawn from the first stage can, for example, have an average particle size of between 60 and 200 mm, while the fraction of the material mixture withdrawn from the second stage can have an average particle size of, for example, 10 to 60 mm.
  • each stage of the rotor mill is assigned at least one outlet through which the correspondingly comminuted material mixture, which mainly or at best exclusively contains substitute fuel, can be withdrawn.
  • each further stage of the rotor mill are arranged in particular vertically above the first or preceding stage, wherein the tools of each stage are preferably driven by a single common drive.
  • the separation device comprises at least one sieve between each stage of the rotor mill. Such a sieve provides a simple separation device.
  • an annular space is formed which surrounds the first stage of the rotor mill, wherein in particular a grid arrangement functioning as a sieve is arranged between the outer annular space and the tools of the first stage of the rotor mill.
  • the material mixture comminuted in the first stage of the rotor mill can thus pass through the grid arrangement into the annular space, from which the comminuted material mixture can be withdrawn through the at least one first outlet. If a plurality of (more than two) stages are formed, each stage following the first stage up to the last stage can also be assigned its own annular space which is separated from the tools of the corresponding stage by a grid arrangement.
  • stripping elements which can also be referred to as scraping elements, are formed on a radially outer end of some tools of the (first stages of the) rotor mill, with which particles of the material mixture retained on the grid arrangement or a radial wall of the rotor mill can be released from the grid arrangement so that they can be fed to further comminution in the first or the corresponding stage.
  • a cleaning device is assigned to the separating device between the stages of the rotor mill, with which the material mixture retained by the separating device can be released from the separating device.
  • the released material mixture can thus be fed to further comminution in the previous stage, for which purpose, for example, a pulsation of the gas flow is also possible.
  • the cleaning device can also be driven in rotation together with the tools of the previous stage, so that a continuous release of the retained material mixture from the separating device is possible.
  • the device shown in the figures for processing a material mixture consisting of substitute fuel and impurities has a vertically aligned central feed 1 which is radially delimited by a hollow cylinder 12. Above the feed 1, a funnel is formed through which the material mixture is fed into the feed 1.
  • a separating device 2 which comprises a spreading plate 14.
  • the spreading plate 14 is connected to the hollow cylinder 12 in a rotationally fixed manner, so that the spreading plate 14 and the hollow cylinder 12 can be driven in rotation together.
  • tools in the form of wing elements 8a and wires 8b are arranged so that they can be driven to rotate together with the hollow cylinder 12 about the hollow cylinder's longitudinal axis.
  • the tools 8a, 8b form a rotor mill 3 arranged above the separating device 2.
  • the device also comprises a flow device 4 with an inlet 15, a first outlet 7.1 and a second outlet 7.2.
  • the flow device 4 can be operated by blowing in a gaseous operating medium at the inlet 15 or by sucking off the gaseous operating medium at the outlets 7.1 and 7.2.
  • the device is designed in its interior in such a way that the operating medium entering through the inlet 15 flows upwards past the radially outer edge of the spreading plate 14 into the rotor mill 3.
  • the rotor mill 3 has a first stage 5.1, to which the first outlet 7.1 is assigned.
  • the rotor mill 3 also has a second stage 5.2, to which the second outlet 7.2 is assigned.
  • the tools 8a and 8b of the first stage 5.1 are radially surrounded by a grid arrangement 10, which separates the tools from an annular space 9.
  • a separating device 6 in the form of a sieve is also formed.
  • the first stage 5.1 and the second stage 5.2 of the rotor mill 3 each comprise a plurality of wing elements 8a arranged in groups in a helical manner on the outside of the hollow cylinder 12, which extend from the outside of the hollow cylinder extend radially outwards.
  • the wing elements 8a are aligned at an angle to a horizontal plane.
  • Plate-shaped impact elements 13 are attached to the outer ends of the wing elements 8a.
  • scraper elements 11 are attached to some wing elements 8a, with which components of the material mixture held back by the grid arrangement 10 can be released from the grid arrangement 10.
  • scraper elements can also be attached indirectly to the hollow cylinder 12 as a cleaning device, with which material held back by the separating device 6 can be released.
  • the first stage 5.1 and the second stage 5.2 each have wires 8b as tools, which are attached to the outside of the hollow cylinder 12.
  • a material mixture consisting of substitute fuel and impurities is introduced into the vertically aligned central feed 1, in which the material mixture sinks downwards to the separating device 2 comprising the spreading plate 14. Due to the joint rotational movement of the spreading plate 14 and the hollow cylinder 12 delimiting the feed 1, the material mixture is accelerated radially outwards at the latest when it reaches the spreading plate 14. The material mixture passing over the outer radial edge of the spreading plate 14 is sifted due to the rising gas flow, so that mainly impurities sink downwards in the space surrounding the spreading plate 14, while the remaining material mixture, which mainly contains substitute fuel, enters the first stage 5.1 of the rotor mill 3 with the gas flow.
  • the material mixture is crushed by interaction with the tools 8a and 8b and with each other. Due to the vertical and circumferentially offset arrangement of the tools 8a, 8b, effective crushing can take place, whereby crushed Material can pass through the grid arrangement 10 into the annular space 9, whereby this part of the material mixture is withdrawn from the first outlet 7.1.
  • the material mixture passing through the separating device 6 is further crushed in the second stage 5.2, so that the material mixture exiting from the second outlet 7.2 has a smaller average particle size than the material mixture exiting from the first outlet 7.1.
  • the device not only enables particularly efficient comminution, but can also produce material mixtures with different particle sizes.
