Definitions

  • the invention relates to a system for drying and processing of Free-flowing mineral material, in particular coal.
  • Mineral good falls in the extraction and Processing mostly in the form of a mixture of particulate or granular Good and fine grained and dusty good.
  • To get this mixture in specified fractions for example general cargo, coarse-grained, fine-grained and to be able to separate dusty material, the proportion above a given Kom bemessers as piece goods by sieving separated.
  • To from the sieve passage the coarse fraction of To be able to further separate fine-grained and dust-like fraction, must Screen passage are first dried.
  • As an aggregate for drying Mineral mixtures have proven themselves rotary drums.
  • Rotary drums for drying moist mineral material are in Direction of conveyance of the goods to be dried inclined drums, through the either in countercurrent or in cocurrent to the material to be dried hot flue gases are introduced from an incinerator.
  • in the DC plants are operated when fresh abandoned moist good with the freshly introduced hot flue gases to Achieve a rapid drying success in contact while the countercurrent process is used, for example, if the already pre-dried good to expel the last Moisture residues with the hot flue gas in the state of the highest Drying capacity to be brought into contact.
  • a co-current operated rotary kiln of the type mentioned is from US Pat. No. 4,318,620.
  • the technical problem underlying the invention is a Plant for drying and processing of free-flowing mineral material develop in which the intensity of stabilization is high and good Environmental compatibility is given.
  • the plant according to the invention has the advantage that the discontinuous moist mixture is brought into contact immediately with the task in the rotary drum with the fresh, not yet cooled hot flue gases and is heated in shock. As a result, the soft grains, which preferentially absorb water, decompose by decrepitation. Upon further passage through the rotary drum, the material to be dried is lifted by the internals in a position in the upper region of the rotary drum to then fall over as long as possible in the drum down, with a further stabilization occurs. The sucked in the conveying direction flue gas flow forms a strong flow, which detects the dusty and fine-grained constituents and contributes. The flow rate is increased by the venturi installation.
  • the subclaims relate to advantageous embodiments. Because of the engagement A variable speed fan is influencing the suction and thus the negative pressure in the drum advantageously possible. This can also be the Intensity of stabilization can be influenced. Because of the venturi installation aspirated gas streams are dust laden, by only partially Formation of the fins causes no materials in Venturi installation build up or build up, which increases the flow resistance in the drum would increase.
  • the suction is not Preheated fresh air avoided. Due to the fact that the bypass opening in the Drum jacket is arranged only at a distance behind the inlet end is causes the suctioned directly at the inlet end of the ambient air Flow through the annular gap between the drum shell and double jacket is preheated, so that the heating to support the drying used and the drying is not by preheating not preheated, cooler Ambient air is adversely affected. Due to the thermal insulation of the Double mantle and the peripheral boxes will cause the out of the drum radiated heat to preheat the bypass gas is effective and not lost by radiation to the environment.
  • the formation of internals as alternating straight plates and alternating in the longitudinal direction pocket-forming bent plates causes a Mixing of the goods to be dried and lifting the to drying material when rotating the drum to the top areas of the drum volume.
  • the arrangement of a fixed rotatably mounted Impact wheel such that at least one peripheral ring rolls against it, prevented in an advantageous manner that the rotary drum in the tilt direction is moved.
  • the formation of the upward gas flow in the shaft leads to an air classification of the discharged good in such a way that the Grainy good falls down against the gas stream, while the finest grained and dust-like material with the gas flow up to the transfer device in a dedusting system is performed.
  • Fig. 1 the rotary drum 1 in a side view in a cut form shown.
  • left of the rotary drum 1 is a Combustion device 2 shown schematically.
  • the transfer device 22 In the entrance side of the Rotary drum flows the flue gas stream of the combustion device, the represented by a large arrow in the flow direction and the Rotary drum 1 leaves on the exit side in the shaft 6 and there after is guided above to the transfer device 22, which leads to a dedusting system leads.
  • Behind the transfer device 22, a fan 7 is arranged for a corresponding negative pressure and suction in the rotary drum 1 and in Shaft 6 provides.
  • the Entry device 23 the material to be dried in the rotary drum. 1 given up.
  • Gas flow in the rotary drum which is essentially the flue gases of Incinerator 2 includes. This gas flow is through the coaxial Venturieinbau 8 out, whereby the flow rate is increased. From the gas flow finest-grained and dust-like particles are detected and discharged into the shaft 6. At the discharge end of the rotary drum 1 is also the lumpy and granular dry material discharged into the shaft. As in the Shaft 6 is formed a vertical flow, it acts like a Wind sifter and leads the fine-grained and dust-like parts of the dried goods with it up to the gateway 22, from where the Dust and Feinstkorn loaded gas stream to a downstream Dedusting system is performed.
  • the rotary drum is inclined ⁇ in the conveying direction by an angle and has two longitudinally spaced peripheral rings 18, on which the Rotary drive 19 attacks.
  • the rear in the conveying direction peripheral ring 18 rolls a stop wheel 20 from which is rotatably mounted stationary, thereby preventing is that the rotary drum is moved axially in the conveying direction.
  • the Injector 23 and the discharge device 21 can both as a band be designed as a worm, with a worm advantages in the Has sealing.
  • FIG. 2 the indicated in Fig. 1 by a dot-dash line Section II shown on an enlarged scale, showing the structure of the bypass 9 in the drum shell shows.
  • an opening 10 is arranged in the drum shell, the Peripheral box 16 is covered. Of the openings 10 can over several the circumference be distributed, the total of a gas-tight annular Peripheral box 16 are covered.
  • About a coaxial double jacket 24 is the box 16 connected to a second peripheral box 17, wherein the Double jacket 24 an annular gap 14 between the drum shell and Double jacket 24 forms.
  • the second peripheral box 17 is also at least one opening 12 is arranged to the environment, by an after externally biased flap 13 is sealed inside sealing.
  • the two Peripheral boxes 16 and 17 and the double jacket 24 have a Heat insulation 15 on, which in the representation by a hatched Strip is shown.
  • the operation of the bypass is such that at a corresponding Negative pressure in the rotary drum 1, at least equal to or greater than the Biasing force of the flap 13 is, by sucking the flap 13, the opening 12th is released so that sucked in ambient air and due to the Heat radiation through the drum shell preheated in the rotary drum be sucked in.
  • Fig. 3 the structure of the coaxial venturi 8 is shown schematically.
  • the baffles are only partially formed, so that between the trained baffles enough free flow area remains. This avoids that at the trained fins attaches too much of the dust load of the gas stream and possibly builds up what otherwise lead to an undesirable increase in flow resistance could.
  • the proportion of trained guide surfaces is sufficient to the gas flow to center and in the manner of a Venturi nozzle the flow velocity too increase.
