Definitions

  • the invention relates to a pyrolysis plant according to the preamble of claim 1.
  • Thermal processes are known for waste disposal, at where the waste is burned in waste incineration plants or in Pyrolysis plants pyrolyzed, i.e. in the absence of air Temperature from about 400 ° C to 700 ° C is subjected. at Both methods make sense after the combustion or to separate the residue remaining after pyrolysis, to either recycle it or dispose of it in a suitable manner. The aim is to residual material to be disposed of in a landfill as low as possible to keep.
  • the pyrolysis residue also has non-combustible parts.
  • the non-combustible parts essentially consists of an inert fraction, such as glass, Stones or ceramics, as well as composed of a metal fraction.
  • the recyclable materials are sorted out and recycled fed. There are procedures for sorting out and components necessary that are reliable and continuous Ensure operation.
  • the problem with screening devices is often that clog the sieve surfaces. Then the screening device fails, or it must at least be a complex and labor-intensive one Undergo cleaning.
  • the problem of constipation the screening device occurs particularly in the case of a strongly inhomogeneous Composition of the solid to be separated. So for example, wires get caught in screen surfaces Perforated sheets, so that the individual holes first be narrowed and clog up over time.
  • the residue obtained during pyrolysis is typical such a strongly inhomogeneous solid, which with regard to its material composition, its size and geometry its solid parts shows great differences.
  • the residue is next to stones, broken glass and larger metal parts also elongated bars as well as in twisted wires (wire bulges).
  • a discharge device for pyrolysis residues known from a smoldering drum includes a conveyor that has a sawtooth profiled partition with an attached Rod screen has.
  • the partition will vibrate offset so that the fine of the separate coarse parts. The fine parts fall through subsequent rod sieve through, while the coarse fractions slide on the bar screen. Wirewalls can however, hang on the poles and cause constipation to lead.
  • EP 0 086 488 A2 also includes a pyrolysis plant for waste known a screening device for solid, the screening device is rotatable about its longitudinal axis.
  • FR 27 45 204 A1 also discloses the use a rod wound along a helix at one Screening device.
  • the present invention has for its object a Pyrolysis plant for waste with a sieve for solid Specify residual material in the case of continuous operation with simple means is guaranteed without constipation occur.
  • the rod member is substantially parallel to that formed by the spiral outer surface or parallel to the formed by the multi-course screen and acts as a wiping element as follows: a wire bulge gets caught on the pole, this wire bulge is due to the Rotary movement of the sieve against the fixed rod element out and is guided by this along the helix of stripped the rod. To achieve this is the sense of rotation the rod to the direction of rotation of the screening device switched off.
  • the rod is a spiral with several turns, in particular with about four to ten Turns, formed.
  • a screening device which is also called a "spiral screen”
  • the solid to be sieved into the interior formed by the three-dimensional spiral brought in Fine solid with smaller dimensions as the distance between two turns of the spiral falls through the spiral while coarse solid in the interior is further promoted.
  • Spacing between turns can be the maximum size of the sieved finer solids content can be adjusted.
  • a major advantage of the spiral is that any waste parts stuck between two turns be lifted up by the rotary movement and in particular fall at the upper turning point due to their own weight.
  • the simple and robust design of the screening device as a spiral therefore, avoids permanent constipation and enables continuous operation.
  • a number of rods are in a practical embodiment provided, the rod beginnings arranged rotatably are. Each bar runs along a helix. Such a sieve with several rods is also called multi-pass sieve.
  • the angle of rotation of the rods is less than 360 °. In particular is the angle of rotation is less than or approximately equal to 180 °.
  • the rod element is for the most efficient stripping preferably also wound along a helix, and in particular counter to the rod, so that it with the rod, for example, an angle of preferred 90 ° includes.
  • the spiral screen the spiral is attached to only one of its two ends, so that the spiral axis due to its own weight towards its gravity towards its unpaved end is curved below.
  • the spiral is preferred only at the beginning of the spiral held while the spiral end located in the conveying direction is designed to hang freely.
  • the main advantage of curvature is that that the distances of the turns at the bottom of the spiral are smaller than the distances at the top of the spiral.
  • Solid matter introduced into the spiral can in principle only between turns on the lower side of the spiral jam because as soon as it is lifted due to its Dead weight falls down. In other words: through the Spiral movement becomes a jammed solid part with the Spiral raised up. At the same time, the distance is widening of the turns so that the solid part between the turns cannot remain clamped and due to its own weight inevitably falls down.
  • the screening device with curved spiral is therefore highly self-cleaning.
  • a such a spiral is extremely robust and is particularly suitable also for rough separation of heavy and large solids.
  • the spiral is made of plastic, for example.
  • an alignment device is provided in the screening device, which is arranged in the conveying direction in front of the rod, and the flows into the interior.
  • the alignment of the elongated solid parts ensures that this is essentially parallel to the longitudinal axis in the interior can be introduced. Elongated solid parts are therefore also automatically as coarse solid parts treated and promoted. You can't be vertical fall through the spiral to the longitudinal axis. Consequently is guaranteed that by the off the shelf or by the The sieve formed from rods only falls through solid particles, whose largest dimension is smaller than the distance two turns of the spiral or as the distance between two Rods.
  • the alignment device is as one configured drum rotatable about its longitudinal axis. by virtue of the solid parts are aligned with the rotary movement of the drum automatically in the direction of the drum axis.
  • the helix is particularly immediately on arranged on the inlet side of the drum and has a relative high flank.
  • the helix is in particular designed such that it - in a plan view seen in the direction of the longitudinal axis of the drum - forms a closed circle. This means that that solids on the drum bottom straight from the drum entrance slide through to the drum exit without any obstacles can. In order not to obstruct the flow of solids unnecessarily, becomes a multi-turn helix with an angle of rotation smaller 360 ° preferred. In this case, the desired overlap the flank reaches and at the same time becomes a relatively flat one Incline of the helix allows for a faster solids transport inside the drum.
  • the alignment device as a profiled oscillating floor with longitudinal grooves designed in which the longitudinal grooves in the conveying direction run and in which the elongated solid parts due the vibrations of the vibrating floor in these longitudinal grooves be aligned.
  • the rod is advantageously on the in the conveying direction end face of the drum attached to this and there especially welded.
  • the rod is preferably attached in such a way that the drum exit in the formed by the rod Interior opens.
  • the rod is out of the drum on the outer wall of the drum or at least attached flush with the drum.

  • the spiral 10 is for example with a suitable welding, screwing or Clamp connection attached to the drum 2.
  • the spiral 10 aligns approximately with the drum 2, so that the diameter the drum 2 and that of the spiral 10 are approximately the same.
  • the drum 2 is rotatably supported. You can't over one drive shown in detail can be set in rotation. Together the drum 2 also rotates the drum 2 attached spiral 10. This has five turns according to Figure 1 on. The distance between two adjacent turns depends on the type of solid R. It is present preferably about 180 mm.
  • the spiral wound Rod 8 is made of a robust material and is special metallic. For example, it is a round bar or a steel pipe.
  • the spiral 10 is only one-sided, namely on the drum 2 attached. Your spiral end facing away from drum 2 is free of fasteners and is not supported. The spiral 10 will therefore become unpaved Bend downward due to gravity. hereupon is discussed in more detail below in FIG. 2.
  • the solid R is the feed device 6 in the Drum 2 is given and is due to the inclination of the drum 2nd and the rotational movement in the conveying direction 14 towards the spiral 10 transported. Fine solid F is separated off in the spiral 10, while coarse solid G is transported further by the spiral 10 becomes.
  • a major advantage of the screening device 1 with the spiral 10 can be seen in the fact that even more fluent Solid R through the rotary movement in a simple manner in the conveying direction 14 is transported.
  • Figure 2 shows a schematic section through a curved Spiral 10. This is the main principle of operation of the curved spiral 10 explained.
  • the spiral axis 12 (and with it the entire spiral 10) points according to Figure 2 shows a curvature. Because of the curvature is the top one Distance o between two successive turns larger than the lower distance u between two turns.
  • On Solid part R can only be in the lower part of the spiral 10 clamp where the distance u between two turns is small.
  • a clamped solid part P is through the Rotational movement of the spiral 10 promoted upward, and at the same time the distance between the turns becomes larger, so that the Solid part P loosens and falls.
  • the smoldering drum 26 of a pyrolysis plant via a feed shaft 27 and a feed device 28 loaded with waste A.
  • the waste A is in the smoldering drum 26 at around 450 ° C. This creates a Smoldering gas S and a solid or pyrolysis residue R.
