Definitions

  • Such tempering may be by heating or cooling of a bulk material. When there is a heat input to the bulk material, then - if this is still a carrier of moisture - at the same time a drying take place. The moisture is then supplied by means of a Gases discharged.
  • bulk materials within the meaning of this invention are understood free-flowing bulk materials, such. Fertilizers, Plastic granules, plastic powder or food but also such. B. granulated sugar.
  • the invention is therefore an object of the invention to provide a device for controlling the temperature of bulk material, which allows a high heat transfer and easy cleaning with a simple structure.
  • This object is achieved by the features of claim 1.
  • the heat exchanger tubes have a large area, based on their cross-section, and high temperature gradients from the middle of the tube to the tube wall, so that a correspondingly intensive heat exchange can take place.
  • suitable liquids such as in particular water, but also gases or steam can be used.
  • the design effort for the supply of the heat transfer fluid is low, since no inlet manifold or outlet collector for the heat transfer fluid is needed. Also, the cleaning on the side of the heat transfer fluid is easy to carry out.
  • the bulk material is guided by gravity through the heat exchanger tubes. These are therefore usually arranged vertically, but can also be slightly inclined relative to the vertical, as long as it is ensured that the bulk material is passed by gravity through the heat exchanger tubes. So that the bulk material flows through the heat exchanger tubes without interference, the inner diameter of the heat exchanger tubes should be at least four to five times the particle size of the bulk material. As a result, a thorough emptying of the pipes is ensured.
  • a plurality of such sections may be provided in succession, so that in each case between two sections, a rearrangement of the bulk material takes place, whereby the temperature profile, which is adjusted from the pipe wall to the core of the bulk material, is made uniform. As a result, the temperature gradient is increased at the pipe wall in the subsequent heat exchange section and improves the temperature of the bulk material.
  • the heat exchange section ie the actual tube bundle heat exchanger, can according to claim 2 in a simple manner a buffer section upstream of the bulk material and according to claim 3, a discharge section be subordinated.
  • a discharge section be subordinated.
  • the measures according to claim 9 lead to an improvement of the heat transfer on the side of the heat transfer fluid, so on the outside the heat exchanger tubes. This effect occurs especially at low Flow rates of the heat transfer fluid, since its Flow rate is increased.
  • the embodiment according to claim 18 provides an advantageous alternative to Embodiment according to claim 4.
  • the claims 19 to 21 give measures again, by an optimal Arrangement of the heat exchanger tubes and in particular a particular thin design of the inlet tube bottom is achieved without the risk of a non-optimal bulk flow or even not optimal emptying of the buffer section would be given.
  • the device shown in Figure 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. Sections 1, 2, 3 each have circular cross sections.
  • the boxy, essentially enclosed buffer section 1 is with an upper inlet spigot 4 provided for supplying a bulk material to be tempered.
  • the heat exchange section 2 has a housing 5 in the interior thereof 6 parallel to each other heat exchanger tubes 7 each with distance are arranged 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 one.
  • Adjacent to the buffer section 1 opens a discharge nozzle 9 from the interior 6 of the housing 5 from.
  • In the interior 6 are deflecting plates 10 each transverse to the longitudinal direction of the tubes 7 in Distance from each other mounted such that a via the supply nozzle. 8 supplied heat transfer fluid according to the flow direction arrow 11 meandering through the interior 6 each transverse to the longitudinal direction 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 with a the Tubes 7 enveloping bed 12 of glass balls, steel balls and Plastic granules filled, which improve the heat transfer between the heat transfer fluid and the tubes 7 contributes.
  • 9 removable Retaining sieves 13 arranged.
  • the size of the particles of the bed 12 should be such that after the preparation of the heat exchange section 2 can be incorporated in these.
  • the particles of the bed In any case, 12 must be smaller than the pitch of the Tubes 7.
  • the particles of the bed 12 preferably have spherical, lens or cylindrical shape.
  • the tubes 7 are at the top in a fixed to the housing 5 connected inlet tube bottom 14 and at the bottom connected to a spout tube plate 15, that they go to the buffer section 1 and to the discharge section 3 are open. 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 consist of flange 16 or 17. Like the Drawing is removed, the inlet tube plate 14 is designed so that each tube 7 a to the buffer section 1 towards expanding, for has respective narrowing tube 7 so narrowing inlet funnel 18, wherein adjacent funnels 18 are again dimensioned to be at the top meet in a relatively sharp edge 19.
  • the inlet funnel 18 have an opening angle ⁇ , the at least 30 ° and a maximum of 120 ° is, but preferably in the range of 40 ° to 100 °. This will avoided that in the inlet tube plate 14 between adjacent tubes 7 dead spaces or dead surfaces arise on which bulk 20 lie remains, especially when emptying the heat exchange section 2 is not fed to a pipe 7 by gravity and therefore remains lying on the inlet tube plate 14.
  • the discharge section 3 is in the form of a downwardly tapering cone-shaped funnel formed. Such a shape causes that Bulk 20 in the discharge section 3 at all points of any selected Cross section flows at almost the same speed, in this consideration, the immediate wall area is not taken into account is because there is always a delay due to wall friction.
  • a rotary valve 22 is provided, the Housing 23 via a downpipe 24 connected to the discharge section 3 is.
  • a cellular wheel 25 is arranged, which is a motor 26 is rotary drivable.
  • the motor 26 is from a level detector 27th controlled, in turn, the level of the bulk material 20 in the buffer section detected.
  • shut-off 30 In the funnel-shaped discharge section 3 opens a feed line 28 for a gas.
  • a small pressure vessel 29th connected to the upstream in line 28 a shut-off 30 and a shut-off device 31 is arranged downstream.
  • closed shut-off device 31 of the pressure vessel 29 With Compressed gas to be filled.
  • closed obturator 30 can by Opening the obturator 31 with appropriate emptying of the pressure vessel 29 a compressed gas stream in the funnel-shaped discharge section 3 are given.
  • the compressed gas rises and causes a rearrangement of the bulk material in the heat exchanger tubes 7 and thus improving the heat transfer. At the same time this causes Gas a drying of the bulk material 20, if possible.
  • Both shut-off organs 30 and 31 can also be open to a continuous one Gas supply to allow. So that the gas supplied from the Device can also exit again is at the top of the buffer section 1 an exhaust pipe 36 is provided.
  • a guide surface 33 is formed, which the bulk material 20 from the discharge section 3 to the revolving side of the in the direction of rotation 34th rotatably driven cellular wheel 25 passes.
  • the heat exchanger tubes 7 in the longitudinal direction have continuous inner ribs 37, so that in each tube 7 itself again several channels 38 are formed, in the middle of the tube connected to each other.
  • inner ribs 37 ' also meet in the middle of the tube, so that a simple split Pipe 7 at two opposite inner ribs 37 'or a Stemrohr at three or more inner ribs 37 'is formed.
  • the channels 38 ' are completely separated from each other.
  • the pipe 7 also inner ribs 37 ', which meet in the middle of the tube, and other inner ribs 37, which protrude only in the bulk material 20, have.
  • the number of inner ribs 37, 37 ' is 2 to 12 and especially 3 to 8.
  • the inner ribs 37, 37 ' are at equal angular intervals on the circumference of the tube 7 distributed.
  • the inner ribs 37 or 37 ' can straight or twisted, d. H. helically.
  • Such tubes 7 with inner ribs 37, 37 'are usually made Aluminum and are produced by extrusion. Aluminum, but also Bundmetall, such. As copper, have compared to stainless steel Advantage of a 3 to 4 times higher thermal conductivity.
  • Internal ribs 37, 37 'are also opposite the heat transfer surfaces a simple cylindrical tube 7 greatly enlarged while the Heat conduction routes for the supply or removal of heat from the pipe 7 in the bulk material 20 greatly shortened.
  • the embodiment according to FIG. 4 differs from that according to FIG. 1 in that that the device can be operated with negative pressure.
  • the entire device is therefore connected to a suction fan 39, the the buffer section 1, the interior of the heat exchanger tubes 7 and applied to the discharge section 3 with partial vacuum. So this can be maintained, the supply of the bulk material 20 to the inlet nozzle 4 by means of a substantially vacuum-tight feeding device in the form of a cellular wheel lock 40.
  • This lock 40 and the cellular wheel lock 22 close the entire device pressure-tight from.
  • a gas supply and an exhaust pipe are naturally here unnecessary.
  • the inlet tube bottom 14 simplified, namely, trained; So he does not show the feed funnels 18 on.
