Definitions

  • the invention relates to a plant for drying and processing free-flowing mineral goods, especially coal according to the generic term of claim 1.
  • Mineral material falls in the extraction and Processing mostly in the form of a mixture of lumpy or granular Good and fine-grained and dusty good.
  • predetermined fractions for example general cargo, coarse-grained, fine-grained and to be able to separate dusty material
  • the proportion above is first a predetermined grain diameter as a piece goods by sieving separated.
  • the Sieve passage to be dried first.
  • As an aggregate for drying mineral mixtures have proven their worth.
  • Rotary drums for drying moist mineral goods are in Direction of conveyance of the material to be dried inclined drums through which either in countercurrent or in cocurrent to the material to be dried hot flue gases are introduced from an incinerator.
  • Such systems are operated with direct current when it is fresh Released damp material with the freshly introduced hot flue gases Achieve rapid drying success should, while the countercurrent process is used, for example, if the already pre-dried material to drive out the last one Residual moisture with the hot flue gas in the state of the highest Drying capacity should be brought into contact.
  • the technical problem underlying the invention is one Plant for drying and processing free-flowing mineral goods develop in which the intensity of stabilization is high and good Environmental compatibility is given.
  • the system according to the invention has the advantage that the moist mixture which is added is brought into contact with the fresh, not yet cooled, hot flue gases immediately upon being placed in the rotary drum and is heated in a shock-like manner. As a result, the soft grains, which preferentially absorb water, decay through decrepitation.
  • the material to be dried is lifted into a position in the upper area of the rotating drum by the internals, in order then to fall down over the largest possible distance in the drum, with further stabilization occurring.
  • the flue gas stream sucked in the conveying direction forms a strong flow, which captures and carries the dusty and fine-grained components. The flow rate is increased by the Venturi installation.
  • the bypass for conveying air in the drum jacket ensures that additional conveying air is drawn in from the environment when the vacuum in the drum is greater, without this additional conveying air disrupting the air / fuel mixture in the incineration system and thus the optimal combustion, which also very significantly additional NO x formation is avoided.
  • the subclaims relate to advantageous refinements. Because of the engagement of a speed-controlled fan is influencing the suction and thus of the negative pressure in the drum advantageously possible. This can also Intensity of the stabilization can be influenced. Because of the venturi installation sucked gas streams are dust-laden, is only partially by the The formation of the guiding surfaces means that no materials are used in the Venturi installation accumulate or build up, which increases the flow resistance in the drum would increase.
  • the construction of the internals as alternating straight plates and alternating plates bent in the longitudinal direction to form a pocket causes a Mixing the material to be dried and lifting the material drying goods when rotating the drum up to the top of the drum volume.
  • the formation of the upward gas flow in the shaft leads to a wind sifting of the discharged goods in such a way that granular material falls down against the gas flow, while the fine grain and dusty material with the gas flow up to the transfer device in a dedusting system is operated.
  • the rotary drum 1 is a sectional side view shown. In the illustration, one is to the left of the rotary drum 1 Combustion device 2 is shown schematically.
  • the flue gas stream of the combustion device the is represented by a large arrow in the direction of flow and the Rotary drum 1 leaves the shaft 6 on the outlet side and there after is led above to the transfer device 22, which leads to a dedusting system leads.
  • a fan 7 is arranged behind the transfer device 22 and is suitable for a corresponding negative pressure and suction in the rotary drum 1 and in Shaft 6 provides. In co-current with the flue gas flow with the Entry device 23 the material to be dried into the rotary drum 1 given up.
  • the Drum shell designed as transport blades 3 internals in the Area arranged, which is shown hatched in the drawing.
  • the weird built-in transport blades 3 have a curvature that is strongly in Has direction of action acting component.
  • At the transport blades 3 are built-in blades, which in Rows are arranged one behind the other and alternately straight plates 4 and have plates 5 bent in the longitudinal direction to form pockets.
  • the straight ones Plates 4 effect the mixing of the material to be dried.
  • the bent plates 5 take in a position in the lower drum area the material to be dried and lift it when the rotary drum 1 rotates by practically 180 ° up to the top drum area, from where that to drying goods falling down over a great height.
  • the negative pressure generated with the help of the fan 7 creates a Gas flow in the rotating drum, which is essentially the flue gases of the Combustion device 2 comprises.
  • This gas flow is through the coaxial Venturi installation 8 performed, whereby the flow rate is increased.
  • Fine-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 goods are discharged into the shaft. Since in Shaft 6 is a vertical flow, it acts as a Air classifier and leads the fine-grained and dusty parts of the dried goods with themselves up to the transfer device 22, from where the Dust and fine grain loaded gas stream to a downstream Dedusting system is performed.
  • the rotary drum is inclined and has an angle ⁇ in the conveying direction two longitudinally spaced circumferential rings 18 on which the Rotary drive 19 attacks.
  • the rear circumferential ring 18 rolls in the conveying direction from a stop wheel 20, which is rotatably mounted, thereby preventing is that the rotary drum is moved axially in the conveying direction.
  • the Entry device 23 and the discharge device 21 can both as a belt as well as a snail, with a snail advantages in Has seal.
  • FIG. 2 the one shown in FIG. 1 by a dash-dotted line Section II shown on an enlarged scale showing the structure of the bypass 9 in the drum jacket shows.
  • an opening 10 is arranged in the drum shell, which from Circumferential box 16 is covered.
  • Several of the openings 10 can be distributed around the circumference, total of a gastight annular Circumferential box 16 are covered.
  • Is over a coaxial double jacket 24 the box 16 connected to a second peripheral box 17, the Double jacket 24 an annular gap 14 between the drum jacket and Double jacket 24 forms.
  • the second circumferential box 17 is also at least one opening 12 is arranged to the environment through a outside biased flap 13 is sealed inside.
  • the two Circumferential boxes 16 and 17 and the double jacket 24 have a Thermal insulation 15, which is hatched in the illustration Stripe is shown.
  • the mode of operation of the bypass is such that with a corresponding Vacuum in the rotary drum 1, which is at least equal to or greater than
  • the biasing force of the flap 13 is the opening 12 by suction of the flap 13 is released so that ambient air is sucked in and as a result of Heat radiation through the drum jacket preheated into the rotating drum be sucked in.
  • Fig. 3 the structure of the coaxial venturi 8 is shown schematically.
  • the guide surfaces are only partially formed, so that sufficient free flow cross-section between the formed guiding surfaces remains. This avoids that the trained guide surfaces attaches too much of the dust load of the gas flow and possibly builds up what otherwise lead to an undesirable increase in flow resistance could.
  • the proportion of guiding surfaces designed is sufficient to cover the gas flow center and the flow velocity in the manner of a Venturi nozzle increase.
