Definitions

  • thermal conversion of solid fuels is often carried out under elevated pressure and temperature with the aim of a synthesis raw gas with high energy content and / or to produce a composition favorable for further chemical syntheses.
  • Possible thermal conversion processes may be, for example, the pressure combustion or the pressure gasification by the fluidized bed or entrained flow process.
  • Gas supply elements are introduced in the conical part of a pressure pot in order to achieve a fluidization of the solid bed, with the aim of accomplishing a pneumatic delivery out of the pressure pot out.
  • These pipe elements are mounted on the inner sides of the cone, which are equipped with holes for gas supply.
  • a lock container which provides inside the conical container part gas supply elements over which the container is brought to target pressure.
  • the elements are provided with porous elements through which the gas is supplied.
  • the US 2006/013660 A1 describes in detail a fluidizing cone including the required connecting flanges attached to a container.
  • the conical inner walls are according to the description of porous material.
  • the CH 209 788 describes a storage container for dusty goods with opening into a downpipe funnel, in which a thin layer of air on the funnel wall migrates towards the downpipe without approaching the funnel center, while through the center of the funnel upwardly rising air the dust out to the Funnel wall urges and thereby prevents the formation of bridges.
  • the DE 20 2008 00 4 988 U1 discloses a silo for bulk goods.
  • silo is out of the FR 758 608 known.
  • the gaps are formed by laterally overlapping cone sectors. In further embodiments, it is provided that the gaps run in an oblique direction and the gas outlet side is aligned in a spiral manner in both the tangential and in the direction of the outlet opening, and therefore also has a radial-vertical component. It can further be provided that the gaps are formed by overlapping portions in the form of oblique conic sections.
  • the gaps are closed by cover plates which have round or slot-shaped openings.
  • the openings may also be formed in a nozzle shape.
  • the thickness of the cover sheets may be selected to be 3 times larger than the bore diameter to impart a direction to the gas jet.
  • the openings can be provided at smaller intervals in the upper area of the column than in the lower area of the column.
  • the holes in the upper region may also have larger cross sections than in the lower region, so that a gas flow which is related to the cone cross-sectional area and adapted to the respective height can be supplied.
  • outlet pipes or the outlet nozzles can also be used in further advantageous embodiments, wherein the spatial angles at which the gas jet enters the discharge cone can be selected.
  • Ideal are Hereby, depending on the material to be removed, angle to the horizontal of 30 degrees directed upward or downward, and directed by up to 45 degrees in the horizontal plane, measured from the circular tangent, which abuts the gas outlet point, inwards towards the central axis of the discharge cone.
  • Fig. 1 shows a storage container 1 with a discharge cone 5 according to the invention
  • Fig. 2 and 3 show a discharge cone with columns that run in the vertical direction
  • Fig. 4 shows a variant with modified inlet openings
  • Fig. 5 shows a Austragskonus with columns having an oblique angle to the central axis.
  • Fig. 1 shows a storage container 1 with a discharge cone 5 according to the invention, in which the finely ground fuel 2 is conveyed pneumatically or gravimetrically.
  • the gas 3 leaves the storage container 1 via the gas filter 4, while the finely ground fuel reaches the storage container 1, where it sinks into the discharge cone 5.
  • the gas 3 is in the case of a pneumatic filling of the storage container 1 from the conveying gas and from the gas, which is displaced by the introduced solid in the container.
  • the gas 3 consists essentially of displaced gas.
  • the discharge cone 5 encloses a pressure jacket 6, which is acted upon by compressed gas 7.
  • the deduction 9 of the finely ground fuel takes place through the lock 8.
  • Fig. 2 and 3 each show a discharge cone 5 with columns 10 which extend in the vertical direction, and from which the gas 3 flows in the tangential direction.
  • Fig. 2 also shows half the opening angle ⁇ of the discharge cone.
  • the gaps are closed with sheets 11, in which bores 12 are introduced, can be introduced through the compressed gas 7 from the pressure jacket 6 in the discharge cone 5.
  • Fig. 3 Columns 10, which are hidden from the center line and have a shoulder 13, are those in FIG Fig. 2 shown columns 10 open.
  • the variant shown has the advantage that no bulk cone can build up before the holes 12 and a backflow of finely ground Fuel 2 through the holes 12 in the pressure jacket 6 is also omitted if just no gas pressure is applied there, such as intermittent operation.
  • the variant is in Fig. 3 to build something more elaborate.
  • Fig. 4 shows the in Fig. 3 illustrated variant with modified inlet openings to reduce the high stress of the cone wall by the tangential outflow of the gas jet from the opening in the gap 10.
  • the inlet openings are here modified so that the beam direction of the exiting gas jet can be spatially aligned.
  • This can be achieved by constructing the sheets 11 (in Fig. 4 not shown) in the columns 10 performs very solid and correspondingly fine holes 12 provides that are embedded in defined angles in the sheets 11, or by thin sheets 11 provides where thin outlet pipes or outlet nozzles 14 are mounted, for example by simple Bending can be aligned in the right direction.
  • such outlet tubes or outlet nozzles 14 are mounted flush on the inner side of the cone and thereby projecting on the side facing the outer space, so that it is possible to align the jet direction with simple means on the projecting side.
  • the following angles are advantageously established. This is based on a Cartesian coordinate system having its point of origin in the puncture point, one vertical yz plane of which runs parallel to the cone central axis and whose other vertical xy plane intersects the cone central axis and whose third xz plane is the horizontal plane. Be considered in Fig. 4 the angles of the axis of the outlet tubes and the outlet nozzles 14 on the outside of the discharge cone, where they can be easily measured in the assembled state. The same applies analogously to the corresponding gas outlet angles into the discharge cone.
  • the angle ⁇ between the projection 15 of the beam axis, which corresponds to the axis of the outlet tubes or the outlet nozzles 14, on the horizontal xz plane, and the tangent 16, which rests on a horizontal section of the cone and passes through the origin point of the coordinate system between 0 and 45 degrees.
  • the angle ⁇ between the beam axis corresponding to the axis of the exhaust pipes or the exhaust nozzles 14 and the horizontal xz plane is in the range of 30 degrees upward to 30 degrees downward.
  • Fig. 5 shows a further discharge cone with downward columns 10, which extend in a spiral direction.
  • the columns 10 are also closed with sheets 11, in which holes 12 are recessed, can be introduced through the compressed gas 7 from the pressure jacket 6 in the discharge cone 5. Due to the spiral arrangement, a discharge behavior of the finely ground fuel can be achieved as in a liquid nozzle.
