Definitions

  • bulk material heat exchanger devices occur in the level control problems. These problems, which are due to numerous causes, mean that different bulk material temperatures can occur at the outlet of the bulk material heat exchanger. Furthermore, an interruption is necessary when carrying out cleaning work. Finally, in case of blockages or partial blockages of the bulk material heat exchanger considerable disturbances may occur.
  • EP 0 973 716 B1 discloses a bulk material heat exchanger which is designed to cool crystalline carboxylic acids.
  • the bulk material is fed to the heat exchanger in the lower region and fluidized there.
  • the coarser particles flow down from below.
  • the finer particles are transported in a fluidized bed through a cooling zone and discharged from the heat exchanger above the cooling zone.
  • the conveying air is drawn upwards and can be used for downstream transport to a silo.
  • the invention is therefore based on the object, a device of the general type in such a way that a trouble-free operation is possible.
  • the essence of the invention is that when exceeding a predetermined by the location of the inlet opening of the overflow pipe in the buffer section bulk material level in the buffer section, the bulk material flows through the overflow pipe and only after the bulk material heat exchanger again is merged with the bulk material flow, which adjusts a mixing temperature in the bulk material. In case of a temporary decommissioning by a malfunction, z. As a blockage, the bulk material heat exchanger, the entire flow of bulk material can flow through the overflow pipe. As a rule, the discharge sluice is operated in such a way that a considerable proportion, as a rule at least 80 percent of the normally occurring quantity of bulk material, is passed through the bulk material heat exchanger.
  • going quantities are then passed through the overflow pipe as it were in the bypass on the bulk material heat exchanger.
  • the overflow pipe has a large nominal diameter, which is usually larger than that of a upstream pneumatic conveying line, is supplied via the bulk material. With a large nominal size, the bulk material can flow through the overflow pipe without causing excessive pressure loss.
  • the bulk material heat exchanger is integrated with the overflow pipe in a pneumatic conveying line, wherein the supplied with an incoming feed line bulk material at least predominantly in the bulk material heat exchanger is heated and wherein the conveying air is passed through the overflow pipe at the bulk material heat exchanger and is merged behind this again with the bulk material flow.
  • the overflow pipe has a large nominal diameter.
  • the bulk material heat exchanger downstream as discharge organ rotary valve then there is no differential pressure at this. Such a differential pressure would namely lead to leakage air, which would flow counter to the bulk material in the bulk material heat exchanger and would lead to disturbances of the bulk material flow. Such a negative effect would occur especially in fine-grained or powdery bulk materials.
  • the tempered in the bulk material heat exchanger bulk material can also be introduced into a downstream delivery line, including the development according to claim 5 indicates a solution.
  • Claim 9 finally shows that a closed conveying gas circuit can also be provided, which may be expedient in particular when nitrogen is used as conveying gas instead of conveying air.
  • the bulk material heat exchanger can be designed in the usual way.
  • the product can by parallel arranged plates or transversely to the flow direction of the bulk material pipes of various different Cross-sectional shape in which the heat transfer fluid flows flows; but is particularly advantageous embodiment according to claim 10.
  • Claim 11 specifies a concretization of the cross-sectional conditions of the pneumatic delivery line and the overflow pipeline, wherein it is ensured by these cross-sectional relationships that a regulation of the bulk material level in the buffer section is not required.
  • the apparatus shown in FIG. 1 for controlling the temperature of bulk material has an upper buffer section 1, a middle heat exchange section 2 and a lower discharge section 3.
  • the sections 1, 2, 3 each have circular cross sections.
  • the housing-like, substantially enclosed buffer section 1 is provided with an upper inlet nozzle 4 for supplying a bulk material to be tempered.
  • the inlet nozzle 4 is preferably introduced tangentially into the buffer section 1 in order to effect a good separation of the bulk material along the inner wall of the buffer section 1.
  • This device is also referred to below as a bulk material heat exchanger.
  • the heat exchange section 2 has a housing 5, in whose interior space 6 heat exchanger tubes 7 are arranged parallel to each other at a distance from each other.
  • the interior 6 is therefore a heat exchange space.
  • Adjacent to the discharge section 3 opens into the interior 6 of the housing 5 of the heat exchange section 2, a supply nozzle 8 for heat transfer fluid.
  • Adjacent to the buffer section 1 opens a discharge nozzle 9 from the interior 6 of the housing 5.
  • deflecting plates 10 are each transversely to the longitudinal direction of the tubes 7 at a distance from each other mounted such that a supplied via the supply nozzle 8 heat transfer fluid according to the flow directional arrow 11 meandering through the interior 6 each transverse to the longitudinal direction of the tubes gradually upward to the discharge nozzle 9 flows.
  • the heat exchange section 2 is therefore for a cross-countercurrent designed the heat transfer fluid.
  • the interior 6 can be filled with a tube 7 enveloping bed 12 of glass beads, steel balls and plastic granules, which contributes to the improvement of the heat transfer between the heat transfer fluid and the tubes 7.
  • removable retaining sieves 13 are arranged in the socket 8, 9.
  • the size of the particles of the bed 12 should be such that they can be introduced into them after the heat exchange section 2 has been manufactured.
  • the particles of the bed 12 must therefore in any case be smaller than the pitch of the tubes 7.
  • the particles of the bed 12 are preferably spherical, lens or cylindrical shape.
  • the tubes 7 are connected at the top in an inlet tube plate 14 fixedly connected to the housing 5 and at the bottom with an outlet tube plate 15 in such a way that they are open towards the buffer section 1 and the discharge section 3. Between the buffer section 1 and the heat exchange section 2 on the one hand and the heat exchange section 2 and the discharge section 3 are flange connections 16 and 17. As the drawing is removed, the inlet tube plate 14 is configured in that each tube 7 has an inlet funnel 18 which widens toward the buffer section 1 and thus narrows towards the respective tube 7, with adjacent funnels 18 in turn being dimensioned so that they meet at the top in a relatively sharp edge 19.
  • the inlet funnels 18 have an opening angle ⁇ which is at least 30 ° and at most 120 °, but is preferably in the range from 40 ° to 100 °. This avoids that in the inlet tube plate 14 between adjacent tubes 7 dead spaces or dead surfaces arise on which bulk material 20 remains, which is not supplied to a pipe 7 by gravity, especially when emptying the heat exchange section 2 and therefore remains on the inlet tube sheet 14.
  • the discharge section 3 is in the form of a downwardly tapered cone-shaped funnel. Such a shape causes the bulk material 20 flows in the discharge section 3 at all points of an arbitrarily selected cross section with almost the same speed, in this consideration, the immediate wall area is not taken into account, since there is always a delay due to wall friction.
  • a cellular wheel lock 22 is provided, the housing 23 is connected via a downpipe 24 with the discharge section 3.
  • a cellular wheel 25 is arranged, which is rotatably driven by a motor 26.
  • cellular wheel locks are of course other discharge facilities into consideration, such. B. discharge screws, vibrating troughs or metering slides.
  • an overflow pipe 27 This overflow pipe 27 leads past the heat exchange section 2 and at the discharge section 3 and opens below the feeder lock 22 serving as a sluice in a discharge pipe 28.
  • the inlet opening 29 of the overflow pipe 27th is about
  • the bulk material level 30 in the buffer section 1 is approximately such that at a bulk material reaching or exceeding the inlet opening 29 of the overflow pipeline 27 Mirror 30 overflowing bulk material 20 flows through the overflow pipe 27. Due to the tangential feeding of the bulk material through the inlet nozzle 4 in the buffer section 1, a uniform, ie approximately level equal filling of the buffer section 1 is achieved. This ensures that not too much bulk material is entrained with the conveying air in the overflow pipe 27.
  • the outflow of bulk material 20 through the overflow pipeline 27 may be zero.
  • fluctuations in the bulk material supply via the inlet nozzle 4 can be compensated.
  • disturbances in the bulk material transport through the heat exchange section 2 and in the area of the cellular wheel lock 22 can be compensated.
  • Fig. 2 shows a bulk material heat exchanger on a silo 31.
  • the buffer section 4 is supplied via a pneumatic conveying line 32 in the conveying direction 33 bulk material 20, which enters through the inlet nozzle 4 in the buffer section 1.
  • the promotion of most of the bulk material 20 takes place through the heat exchange section 2 and the discharge lock 22 and the discharge pipe 28 in an inlet 34 of the silo 31.
  • the through the feed line 32 with the bulk material 20 in the buffer Section 1 funded conveying air is completely conveyed through the overflow pipe 27 into the silo 31 and exits there through an exhaust port 35.
  • a filter 36 is regularly arranged.
  • This configuration and arrangement is particularly suitable when using particularly large silos 31 with a large diameter, namely where the inlet 34 and the exhaust air nozzle 35 have the greatest possible distance, for example, 10 m from each other, so that a sufficient calming of the entering into the silo 31 conveying air takes place.
  • a bulk material heat exchanger is integrated in a pneumatic conveying line 37 and thus stands under overpressure or underpressure during operation, since in principle a suction or a pressure feed can take place in the pneumatic conveying line 37.
  • the delivery line 37 occurs - as already described in Fig. 2 - via the inlet nozzle 4 in the buffer section 1 a.
  • the overflow pipe 27 is thus part of the air conveyor system, wherein only in the region of the heat exchange section 2, the conveying air and the bulk material 20 are at least largely separated from each other. Behind the discharge lock 22 of the bulk material flow and the conveying air are brought together again.
  • a switch 39, 40 are provided in each case, which are connected to one another via a bypass line 41.
  • the bulk material 20 can then be conveyed past the device.
  • a radiator 27 a is integrated into the overflow pipe 27, so that the conveying air is cooled.
  • Such a cooler 27a may be, for example, a double-pipe or shell-and-tube heat exchanger.
  • the bulk material 20 is fed to the buffer section 1 by gravity.
  • it is in the bulk material 20 to plastic granules, which is supplied from an extruder 42 with subordinate underwater granulation 43 a dryer 44. From there, it passes through a classifying sieve 45 by gravity via the inlet nozzle 4 into the buffer section 1.
  • the discharge gate 22 is hereby followed by a so-called closed pre-container 46, into which the discharge pipe 28 discharges.
  • the overflow pipeline 27 also opens into this pre-container 46, from which a motor-driven cellular wheel lock 47 serving as a feed lock enters the bulk material 20 into a pneumatic delivery line 48.
  • the conveying air is generated by means of a blower 49.
  • the promotion takes place in the conveying direction 33.
  • the leaking from the cellular wheel lock 47 in the pre-tank 46 leakage air is discharged via the overflow pipe 27 into the buffer section 1, from which it exits through an exhaust port 50.
  • the delivery through the delivery line 48 takes place to silos 51, 52.
  • FIG. 5 differs from that of FIG. 4 only in that the supply of the bulk material 20 already takes place via a pneumatic conveying line 32, as is the case with the arrangement according to FIG. 2.
  • the entire conveying air is blown off from the pneumatic conveying line 32 via the exhaust air nozzle 50.
  • the arrangement of Figure 6 differs from that of Figure 5 in that a cycle of the conveying gas is provided; This is for example of interest if, instead of conveying air nitrogen is used as a conveying gas.
  • the first feed line 32 bulk material 20 is input via the inlet nozzle 4 in the buffer section 1.
  • the exhaust pipe 50 is connected via a connecting line 53 with a radiator 54 and a safety filter 55 to the blower 49.
  • the leakage air from the cellular wheel lock 47 and the upstream pre-tank 46 via the overflow pipe 27 into the buffer section 1 and fed from there via the exhaust port 35 and the connecting line 53 of the second delivery line 48.
