German Patent Application Publication No. 102007027967A1 German Patent Application Publication No. 102004044586A1 German patent No. 4312941C1 German Patent No. 102006049437B3 European Patent Application No. 2159526A2

  The object of the present invention is to improve an apparatus for cooling or heating a bulk material of the type mentioned at the outset so that a high heat transfer coefficient to the bulk material in the heat exchanger module is provided. is there.

  This problem is solved according to the invention by a device with the configuration of claim 1.

  According to the present invention, as proposed in the above-mentioned Patent Document 1 and German Patent Application Publication No. 102004041375A1, it is possible to cause the temperature adjusting gas to flow through the heat exchanger module in a counterflow with respect to the bulk material. It is not the only possibility for efficient heat transfer to the bulk material in the heat exchanger module, but it is equally possible to let the temperature-adjusting gas flow through the heat exchanger module in parallel with the bulk material. I came to realize that the coefficient is guaranteed. The parallel flow transportation of the temperature adjusting gas can be realized with less structural cost than the normal flow transportation. Undesirable fluidization or vortexing of the bulk material conveyed to flow through the heat exchanger module by gravity can be avoided as compared to the countercurrent flow of the temperature regulating gas. The device is configured such that the bulk material is conveyed by gravity in the region of the bulk material heat exchanger module. This means that the bulk material can be conveyed by gravity so as to flow through the heat exchanger module. In other words, this condition is met when the bulk material fills the heat exchanger module by gravity. The temperature adjusting gas supply device may include a gas processing unit for heating, cooling, drying, or ionizing the temperature adjusting gas. Further, the temperature adjustment gas supply device may include a gas amount changing element, for example, a pulsator or a periodic valve (tact valve) for generating a temperature adjustment gas pulsation parallel flow by the bulk material heat exchanger module. You can do it. It is also possible to cause the temperature adjusting gas to flow alternately as a parallel flow and a counter flow with respect to the bulk material in the heat exchanger module by configuring the temperature adjusting gas supply device correspondingly. The temperature regulating gas can flow through the heat exchanger module at a high gas velocity in parallel flow. In general, given normal boundary conditions, the higher the gas velocity of the temperature control gas flowing through the bulk heat exchanger module, the better the heat transfer between the temperature control gas and the bulk material. Is done. Further, the larger the average particle diameter of the bulk material, the larger the gas velocity of the temperature adjusting gas can be selected if other conditions are unchanged. That is, if the bulk material particles are large, the apparatus can be operated with a good heat transfer coefficient. This is particularly advantageous because heat transfer to the core of normal particles becomes more difficult as the particle size increases. Therefore, the device can provide efficient heat transfer even when the particle size is large. In the case of the temperature control device, when the flow through the bulk material heat exchanger module is guided in parallel flow, the same bulk material heat exchanger module supply unit is used for the temperature control gas on the one hand and for the bulk material on the other side. A bulk material heat exchanger module discharge can be used. For example, if a bulk heat exchanger module has a large number of heat exchanger tubes extending between the supply and discharge sections, both the temperature control gas and the bulk material flow through the heat exchanger tubes in parallel flow. Guide you to. This ensures efficient heat exchange along the entire path of the temperature regulating gas and the bulk material between the bulk material heat exchanger module supply and the bulk material heat exchanger module discharge.

  The blower fan according to claim 2 causes overpressure in the bulk material carry-in module with respect to the bulk material carry-out module. At this time, the parallel flow induction of the temperature adjusting gas by the bulk material heat exchanger module is forcibly generated. Bulk material production and supply into the bulk material loading module can be performed via a rotary vane gate to ensure pressure separation of the bulk material loading module for product transport upstream. Temperature control gas supply due to overpressure in the bulk material loading module can also be performed by pneumatic production supply of bulk material into the bulk material loading module, in which case the carrier gas for pneumatic production transport is the next stage In the heat exchanger module, the bulk material and the carrier gas can be used in parallel flow.

  The chamber forming apparatus according to a third aspect may be formed by a guide plate in the carry-out module in which the bulk material cannot flow behind or is difficult to flow. The guide plate may be configured as a hopper having a flat taper angle compared to the side wall of the carry-out module. Alternatively, the guide plate may be configured as a discharge taper portion that is closed on the upper side and opened on the lower side. The chamber forming device may be configured as a bulk material carry-out module radial expansion portion that is expanded in the radial direction compared to the outlet of the bulk material carry-out module. The chamber forming device may be configured as a guide taper portion that expands downward in order to force a thin bulk fluidized bed onto the guide taper portion. When a thin bulk fluidized bed is forcibly generated on the induction taper portion, it becomes easy to separate the temperature control gas from the bulk material in the carry-out module. The chamber forming apparatus may be configured as a chamber profile plate that extends in the lateral direction inside the bulk material carry-out module and opens downward. A number of such chamber profile plates may cross each other in the bulk material delivery module.

  The sealing or throttling element according to claim 4 allows the temperature return gas to pass through the bulk heat exchanger module as an undesired tributary from the bulk input module to the bulk transport module by means of the product return pipe as much as possible. To avoid enough, it is used to decouple the pressure in the bulk material delivery module from the pressure in the bulk material delivery module. A rotary vane gate may be used as a sealing or throttling element.

  6. In the case of the temperature regulating gas return pipe according to claim 5, a temperature regulating gas source that is auxiliary connected as part of the temperature regulating gas supply device in order to compensate for leakage of the temperature regulating gas and / or variations in the total amount. May be provided. The temperature control gas supply device may have a particle filter as an auxiliary. It is also possible to automatically return the bulk material or its fines components that are partially entrained together via the temperature control gas return pipe. In that case, an adjustable control valve can be used in some cases. A separator may be arranged in the temperature control gas return pipe and in the product return pipe provided in some cases.

  The injector according to claim 6 serves to generate a negative pressure in the bulk material carry-out module with respect to the pressure in the bulk material carry-in module. This supports parallel flow conveyance of the temperature control gas and the bulk material by the heat exchanger module.

  The use of part of the temperature control gas supplied in counterflow as claimed in claim 7 can be used for pre-drying the bulk material in the carry-in module. The gas quantity distribution of the temperature control gas component induced in parallel flow by the heat exchanger module relative to the temperature control gas component induced by the carry-in module in the counter flow, in particular the product induction element upstream of the bulk material carry-in module Can be set according to the adjustable leak amount, or can be set in advance by a pressure holding valve or a control valve according to claim 8. The volume flow rate of the temperature adjusting gas induced in the counter flow with respect to the bulk material may be significantly smaller than the volume flow rate of the temperature adjusting gas induced in the parallel flow with respect to the bulk material. This volume flow ratio may be 0.5, 0.2, 0.1, or may be smaller.

  With the suction fan according to claim 9, the pressure in the bulk material carrying-in module is higher than that in the bulk material carrying-out module having a negative pressure at this time. In this case as well, a pressure difference occurs, and this pressure difference induces the temperature adjusting gas by the heat exchanger module in parallel flow with the bulk material. The bulk material can be supplied into the carry-in module through the opened transfer pipe, and as a result, the temperature adjusting gas can be sequentially guided through the pipe. The temperature regulating gas may be supplied to the carry-in module via a separate suction connection. If a bulk material return pipe is provided, a suction fan may be arranged in the return pipe, preferably located downstream of the separator.

  The structure is simplified by utilizing the supply pipe according to claim 10 for both bulk material and temperature control gas. The supply pipe may have a ring pipe that sucks the temperature adjustment gas into the supply pipe from the outside.

  The temperature control gas bypass pipe according to claim 11 bridges the charging point of the bulk material into the pneumatic conveyance pipe with respect to the case where the bulk material is further conveyed by air pressure by suction conveyance on the downstream side of the carry-out module. Only the temperature adjusting gas is sucked in via the bypass pipe without the undesirable function that the bulk material contributes to the transport.

  The blocking element according to claim 12 makes it possible in particular to add a pulsating temperature-adjusting gas.

  According to another blocking element of the thirteenth aspect, the induction of the temperature adjusting gas can be changed from the parallel flow induction to the counter flow induction. This can be used to blow off clogs in the heat exchanger module.

  The bulk material bypass pipe according to claim 14, comprising a throttle element in the bulk material bypass pipe, avoids an undesirably large tributary of temperature regulating gas that bypasses the heat exchanger module and passes through the bypass pipe.

  The discharge pipe according to claim 15 allows the temperature adjusting gas to pass through the product discharge section of the bulk material carry-out module. As an alternative or in addition, for cases where a rotary vane gate is used to further transport the bulk material downstream of the carry-out module in order to avoid undesirable pressure losses. The rotary vane gate may be configured with a maximum gap dimension.

FIG. 11 is a top view of one embodiment of a chamber forming device that can be placed in the bulk material unloading module of the bulk material cooling or heating device embodiment of FIGS.

  The apparatus 1 for cooling or heating a bulk material illustrated in FIG. 1 has an upper bulk material loading module 2 configured as a loading portion or a buffering portion. A bulk material heat exchanger module 4 in the form of a heat exchange part in the center of the apparatus 1 is arranged downstream of the bulk material carry-in module 2 in the direction of gravity flow of the bulk material 3. Similarly, in the direction of gravity flow of the bulk material 3, a bulk material carry-out module 5 in the form of a carry-out portion at the lower part of the apparatus 1 is arranged on the downstream side of the heat exchanger module 4.

  The substantially closed casing small carry-in module 2 has an upper supply connection 6 for supplying the bulk material to be cooled or heated. In the supply connection portion 6, a rotary blade type supply gate 7 for distributing the bulk material 3 to the carry-in module 2 is arranged. The rotary vane type supply gate 7 serves to separate the loading module 2 with respect to the upstream bulk material conveying element.

  The bulk material to be cooled or heated is in particular a granular or pellet-shaped bulk material. The particle size distribution of the bulk material may be substantially centered around the maximum value, i.e., it will be a uniform bulk material of substantially the same particle size as is usual for the case of granules. As an alternative, the particle size distribution may be non-uniform, i.e. particles that are significantly different in size, either in the form of a continuous particle size distribution or in the form of a particle size distribution with several maxima. It's okay. Such a non-uniform distribution is usually the case for granular bulk materials. In this case, plastic granules, urea pellets, chemical fertilizer prills, wood pellets or feed pellets. The bulk material may have the typical diameter of a sphere of the same volume, i.e. between 0.1 mm and 15 mm, between 0.5 mm and 8 mm, in particular between 1 mm and 5 mm. In this case, fine powder, dust, or fine particles are not considered. Very small diameter bulk materials such as individual granular bulk materials, powdered bulk materials can also be used. The volume of the upper carry-in module 2 may be so large that the bulk material has a residence time of 2 minutes or less. Basically, residence times longer than this of 30 minutes or less are possible.

  A supply connection portion 6 that is a bulk material supply pipe into the carry-in module 2 opens at the center of the carry-in module 2. Further, a sieving device may be arranged on the upstream side of the supply connection portion 6 in the bulk material conveyance path. The sieving device inhibits or separates coarse and / or fine components (the particle size of which is greater than or equal to the first predetermined limit value or less than the second predetermined limit value). Instead of or in addition to the sieving device 4a, a distributor or a separator may be arranged in front of the supply connection 6 in the bulk material supply path.

  The heat exchanger module 4 has a housing 8, and heat exchanger tubes 9 are arranged in the interior space at intervals and in parallel with each other. That is, the internal space is a heat exchange space. The length / diameter ratio of the heat exchanger tube 9 may be between 15 and 300, in particular between 30 and 250. The heat exchanger tube 9 may have a circular cross section, an elliptical cross section or a rectangular, in particular a square cross section. The heat exchanger tube may extend vertically or inclined inside the heat exchanger module.

  In the internal space of the housing 8 of the heat exchanger module 4, a supply connection portion 10 for heat exchange fluid is opened adjacent to the carry-out module 5. A discharge connection 11 for discharging the heat exchange fluid from the internal space of the housing 8 is opened adjacent to the carry-in module 2.

  The interior space of the housing 8 may be filled with a filler consisting of glass spheres, steel balls and / or plastic granules surrounding the tube 9. The filler contributes to improved heat transfer between the heat exchange fluid and the tube 9.

  The pipe 9 is coupled at its upper end to a supply pipe bottom portion 12 fixedly coupled to the housing 8 so as to open on the carry-in module 2 side and the carry-out module 5 side, and coupled at its lower end to a discharge pipe bottom portion 13. Yes. Between the carry-in module 2 and the heat exchanger module 4 and between the heat exchanger module 4 and the carry-out module 5, there are flange joints 14 or 15.

  The carry-out module 5 has a conical hopper shape that tapers downward. With such a shape, the bulk material in the carry-out module 5 flows at almost the same speed at all points of the arbitrarily selected cross section. In this case, the direct edge region is not considered. This is because a certain degree of deceleration always occurs in this region due to wall friction. As a carry-out device, there is provided a rotary vane type discharge gate 16 arranged at a discharge connection portion 17 of a discharge portion of the carry-out module 5. The rotary vane discharge gate 16 serves to decouple the pressure between the carry-out module 5 and the downstream product guide element.

  Although the rotary vane type discharge gate 16 can be used as a carry-out mechanism into the pneumatic transfer device, this point is not shown. Instead of the rotary vane discharge gate 16, other discharge mechanisms that are sufficiently sealed against the fluid may be used. This type of alternative unloading mechanism includes a double flap gate or screw conveyor that compresses the product for fluid sealing. If the bulk material in the drain pipe has a sufficient sealing action, a long drain pipe provided with a metering slider (or slide valve) may be used as the carry-out mechanism.

  The heat exchanger module 4 is configured such that the bulk material 3 is transported under the action of gravity by all heat exchanger tubes 9 in the region of the heat exchanger module 4.

  The apparatus 1 has a temperature adjustment gas supply device 18. The temperature adjustment gas supply device 18 is configured such that a temperature adjustment gas (for example, air) passes through the heat exchanger module 4 in parallel flow with the bulk material 3.

  The temperature adjusting gas supply device 18 has a fan 19. The fan 19 is coupled to the carry-in module 2 via a temperature adjustment gas supply passage provided with a supply connection portion for supplying the temperature adjustment gas in a blowing manner. A filter device 21 for filtering the temperature adjustment gas flowing in the supply passage is disposed upstream of the fan 19 in the temperature adjustment gas supply passage.

  As indicated by a directional arrow 22 in FIG. 1, the temperature adjustment gas flows from the supply connection portion 20 into the heat exchanger tube 9 and flows through the heat exchanger tube 9 in parallel with the bulk material 3. As indicated by the other direction arrow 23, the temperature adjustment gas flows from the heat exchanger tube 9 into the carry-out module 15.

  In the carry-out module 5, a chamber forming device 24 for forming a temperature adjusting gas chamber 25 in the carry-out module 15 is disposed. The chamber forming device 24 is configured as a hopper extending in a tapered shape, and the taper angle thereof is flatter than the taper angle of the carry-out module 5. The bulk material 3 transported to the discharge connection portion 17 through the hopper opening 26 of the discharge portion of the chamber forming device 24 enters the temperature adjusting gas chamber 25 extending in a ring shape around the chamber forming device 24. Does not invade. The temperature control gas chamber 25 is defined on the inside by a chamber forming device 24 and on the outside is defined by a housing wall 27 of the carry-out module 5. The housing wall 27 has a plurality of temperature adjusting gas communication connections 28 extending into the temperature adjusting gas chamber 25 in the radial direction with respect to the longitudinal axis of the apparatus 1. For example, four such connection connections 28 may be provided. The communication connection portion 28 allows the temperature adjusting gas chamber 25 to communicate with a ring pipe 29 surrounding the carry-out module 5. The ring pipe 29 is fluidly connected to the temperature adjusting gas circulation pipe 30. The temperature adjusting gas circulation pipe 30 communicates the ring pipe 29 with a separator 31 configured as a cyclone. The circulation pipe 30 opens in a tangential direction to the upper part of the separator 31 via a cyclone supply connection part 32. The lower carry-out portion 33 of the separator 31 is fluidly connected to the carry-in module 2 via the product return pipe 34 and the return connection portion 35. In the return pipe 34, a rotary vane type return gate 36 is disposed at the outlet of the carry-out portion 33. The rotary vane return gate 36 serves to disconnect the pressure between the separator 31 and the carry-in module 2.

  A rotary drive unit 37 for the rotary vanes of the rotary vane type discharge gate 16 has a filling level sensor 39 for filling level of the bulk material 3 in the carry-in module 2 via a signal line 38 shown by a broken line in FIG. And signal connection.

  The device 1 operates as follows.

  The bulk material to be cooled or heated is dispensed through the rotary vane type supply gate 7, depressurized and conveyed into the carry-in module 2. From there, the bulk material reaches the carry-out module 5 through the heat exchanger tube 9 of the heat exchanger module 4 due to the action of gravity, and after cooling or heating as appropriate, the pressure is reduced and distributed through the rotary vane type discharge gate 16. And further conveyed. The signal connection between the filling level sensor 39 and the rotary drive 37 ensures that there is always a predetermined bulk filling height in the carry-in module 2, ie in particular when the heat exchanger tube 9 is in operation of the device 1. It is guaranteed that it is filled with loose material 3.

  During operation of the apparatus 1, the temperature adjusting gas is conveyed by the heat exchanger tube 9 in parallel flow with the bulk material 3. This improves the heat transfer between the bulk material 3 and the heat carrier fluid in the heat exchanger module 4. In this case, an overpressure exists in the carry-in module 2 as compared with the carry-out module 5. This overpressure is typically 1 bar, but may be lower, for example 0.5 bar. In principle, overpressures higher than 1 bar are possible. In any case, a pressure of 1.5 bar or 2 bar may be present in the loading module 2.

  The chamber forming device 24 leaves the device 1 in a predetermined manner after the temperature adjusting gas has flowed through the heat exchanger module 4 via the communication connection 28, the ring pipe 29 and the circulation pipe 30 without undesirable blockage. Guarantee that you can. The temperature adjusting gas leaves the separator 31 via the discharge connection 40. The bulk material 3, in particular its fine particles, guided together in the circulation pipe 30 is separated from the temperature adjusting gas in the separator 31 and supplied again to the carry-in module 2 via the return pipe 34.

  The rotary vane gates 7, 16, and 36 are conveying elements for the bulk material 3, and at the same time are sealing elements or metering elements for decompression.

  Next, another embodiment of the apparatus 1 for cooling or heating the bulk material will be described with reference to FIG. Components corresponding to those already described in connection with FIG. 1 are given the same reference numerals and will not be described again in detail.

  In the case of the apparatus 1 of FIG. 2, the carry-in module 41 has an upper bulk material carry-in part 42 and a temperature adjustment gas carry-in part 43 arranged on the downstream side, that is, arranged below the upper part.

  The bulk material carrying part 42 has an upper region with a circular cross section and a lower region with a ring taper hopper 44. The lower region has a taper discharge part 45 extending around the longitudinal axis of the device 1, and the taper discharge part 45 allows the bulk material 3 to be transferred from the bulk material carry-in part 42 to the load module 41. It can reach into the temperature adjustment gas carrying-in part 43 by a gravity action.

  The temperature adjustment gas supply connection part 20 is open to the temperature adjustment gas carry-in portion 43 from the side.

  In the case of the embodiment of FIG. 2, a gas processing unit 46 as a part of the temperature adjustment gas supply device 18 is further arranged between the fan 19 and the supply connection unit 20. The gas processing unit 46 can also realize heating, cooling, drying, or ionization of the temperature adjusting gas.

  In the case of the apparatus of FIG. 2, the chamber forming device 47 is formed as a discharge cone 48 which is arranged in the carry-out module 5 and opens downward, the top of the cone being upward, ie in the direction of the heat exchanger module 4. It is suitable. In the case of the embodiment of FIG. 2, the temperature adjusting gas chamber 25 is formed inside the discharge cone portion 48. A temperature adjustment gas return pipe 49 of the temperature adjustment gas circulation pipe 50 is disposed in the temperature adjustment gas chamber 25. The return pipe 49 protrudes from the housing wall 27 of the carry-out module 5 via a connection member. A separator 51 is disposed in the circulation pipe 50. A filter 52 is disposed in the housing of the separator 51. The housing of the separator 51 has a product discharge portion 53 that is tapered in a taper shape below the filter 52, and the discharge portion of the product discharge portion 53 is fluidly connected to the rotary blade type separation gate 54. ing.

  A fine dust filter 55 such as the filter device 21 of FIG. 1 is disposed in the temperature adjusting gas circulation pipe 50 on the downstream side of the separator 51. A temperature adjusting gas source 56 is fluidly connected to the temperature adjusting gas circulation pipe 50 between the fine dust filter 55 and the fan 19. The temperature adjusting gas source 56 is, for example, a compressed gas network or a compressed air network.

  The apparatus of FIG. 2 operates as follows.

  The bulk material 3 is supplied to the apparatus 1 of FIG. 2 via the rotary blade type supply gate 7 and is guided to the heat exchanger module 4 through the bulk material loading portion 42 and the temperature adjusting gas loading portion 43 by gravity. 1, heat exchange is performed between the bulk material 3 and the heat-carrying fluid. Next, the bulk material 3 is allowed to flow through the carry-out module 5 and is conveyed to the product conveying element on the downstream side of the apparatus 1 through the rotary blade type discharge gate 16.

  The temperature adjustment gas for supporting heat transfer between the bulk material 3 and the heat carrier fluid enters the carry-in module 41 via the temperature adjustment gas carry-in portion 43. At this time, since the supply connection portion 20 is located at a position higher than the chamber discharge portion 45 of the ring taper hopper 44, an undesirable blockage of the supply connection portion 20 due to the bulk material 3 staying in the carry-in module 41 is avoided.

  Most of the temperature adjustment gas flows from the temperature adjustment gas carry-in portion 43 (see the direction arrow 57) through the heat exchange pipe 9 of the heat exchanger module 4 in parallel flow with the bulk material 3, and from there (direction arrow 58). And enters the temperature adjusting gas chamber 25 through the carry-out module 5, enters the return pipe 49 from there, and returns to the fan 19 again through the circulation pipe 50 including the separator 51 and the fine dust filter 55. . If desired, the gas processing unit 46 may perform processing such as heating, cooling, drying, or ionization before entering the temperature adjusting gas into the supply connection unit 20.

  The bulk material component taken into the circulation pipe 50 by the return pipe 49, in particular the fine dust component, is separated via the separator 41 and discharged by the rotary blade type separation gate 54.

  A relatively small amount of the temperature-adjusted gas introduced into the temperature-adjusted gas carrying-in part 43 through the supply connection 20 is transferred to the chamber discharge part 45 (see the directional arrow 59) as the opposite flow of the bulk material 3. It penetrates and the bulk material 3 is used for drying the bulk material 3 in the bulk material loading portion 42. The total amount of the drying / temperature-adjusting gas can be set through a predetermined leakage amount of the bulk material carrying-in portion 42, particularly through the gap interval of the rotary blade supply gate 7. The loss of the temperature adjustment gas in the circulation pipe 50 is compensated by controlling the supply amount of the temperature adjustment gas via the temperature adjustment gas source 56.

  FIG. 3 shows another embodiment of the device 1 for cooling or heating the bulk material, in which components corresponding to those already described in connection with FIGS. 1 and 2 are given the same reference numerals. And will not be described in detail again.

  In the apparatus 1 of FIG. 3, the carry-in module 41 has a pressure holding control valve 60 connected to the bulk material carry-in part 42. The pressure holding control valve 60 makes a predetermined overpressure in the bulk material carrying-in portion 42. When this overpressure is exceeded, the temperature adjusting gas is released through the control valve 60.

  In the case of the embodiment of FIG. 3, another pressure holding control valve 61 is disposed downstream of the temperature adjustment gas return pipe 49 in the temperature adjustment gas circulation pipe 50. The flow inlet 63 of the injector 62 is fluidly connected to the temperature adjusting gas source 56 via the gas processing unit 46. The circulation pipe 50 coming from the return pipe 49 is also opened at the flow inlet 63. Further, the flow outlet of the injector 62 is connected to the temperature adjusting gas carrying-in portion 43 via the supply connecting portion 20 via the circulation pipe 50.

  The device 1 of FIG. 3 operates as follows. In the following, items that have not been described in connection with FIGS. 1 and 2 will be described.

  The temperature adjustment gas that has exited the carry-out module 5 via the return pipe 49 returns to the supply connection unit 20 again via the circulation pipe 50 in the circulation system. The component of the bulk material 3 entrained via the circulation pipe 50 is automatically fed back. In this case, the injector 62 appears to have a sufficiently large pressure difference between the overpressure in the tube portion in the region of the supply connection 20 and the lower pressure in the tube portion in the region of the return tube 49. Therefore, a sufficiently large pressure difference is set between the temperature adjusting gas carrying-in portion 43 of the carry-in module 41 and the bulk material carrying-in portion 42 and the carry-out module 5. The pressure holding control valve 61 is used to adjust the amount of temperature adjusting gas to be sucked out.

  In the case of the apparatus 1 of FIGS. 1 and 3, the temperature adjustment gas is charged into the carry-in module 2 or 41 in a pressurized state, and the parallel flow of the temperature adjustment gas and the bulk material 3 is thus caused in the heat exchange tube 9. Flow through.

  FIG. 4 shows another embodiment of the device 1 for cooling or heating the bulk material, in which the temperature regulating gas is drawn from the carry-out module 5 by means of the heat exchange tube 9 of the heat exchanger module 4. Causes a parallel flow of bulk material. Components corresponding to those described in connection with FIGS. 1 to 3 are given the same reference numerals and will not be described again in detail. Note that the illustration in FIG. 4 is considerably more schematic than the illustration in FIG.

  In the embodiment of FIG. 4, the temperature adjustment gas is sucked through the suction fan 64. The suction fan 64 is fluidly connected to a suction connection portion (not shown) of the carry-out module 5 via a temperature adjusting gas suction conveyance pipe 65. The suction connection portion is implemented in the same manner as the return pipe 49 in FIGS. Between the suction connection portion and the suction fan 64, a separator 66 similar to the separator 51 of the embodiment of FIG. Fine components separated from the bulk material 3 by the separator 66 and entrained by the suction conveyance pipe 65 are returned into the carry-in module 2 through the rotary blade type separation gate 54 and the product return pipe 67.

  The temperature adjusting gas is sucked into the carry-in module 2 via a suction pipe 68 provided with a suction connection (not shown) arranged beside the supply connection 6 for the bulk material 3. A filter such as the filter device 21 is disposed in the suction pipe 98.

  In the variant embodiment relating to suction in FIG. 4, there may be an absolute pressure in the carry-out module 5, for example in the range between 0.3 bar and 0.4 bar, so that the carry-in module 2 and the carry-out module 5 There is a pressure difference in the range between 0.6 and 0.7 bar, for example.

  4a and 4b show a variant embodiment for supplying bulk material / temperature-adjusting gas into the carry-in module 2 through one common supply connection.

  The bulk material / temperature adjusting gas supply connection 69 in FIG. 4a has a tapered portion 70 extending in the bulk material transport direction and a tube portion 71 provided thereafter. The diameter of the tube portion 71 is smaller than the diameter of the tapered portion 70 at the height of the transition to the tube portion. Between the pipe part 71 and the tapered part 70 there is an open supply ring 72 in the region of the transition, through which the temperature regulating gas (see directional arrow 73) passes through the supply connection 69. Then, it can reach into the carry-in module 2 from the outside.

  In the embodiment of the bulk material / temperature regulating gas supply connection 69 of FIG. 4b, a coarse filter or dust trapping grid 74 is further arranged in the supply ring 72, the function of which corresponds to the function of the filter device 21 of the embodiment of FIG. It corresponds.

  Basically, instead of the embodiment of FIGS. 4 and 4b, an embodiment opposite to the temperature adjusting gas supply ring 72 in which the temperature adjusting gas flows from above is also possible.

  FIG. 5 shows a part of a plant for producing polymer granules as an example of the bulk material 3, in which case another embodiment of the device 1 for cooling or heating the bulk material 3 is used. Constituent elements corresponding to those described in relation to FIGS. 1 to 4 are given the same reference numerals and will not be described again in detail.

  In the embodiment of FIG. 5, a storage silo 75 for the bulk material 3 is arranged on the downstream side of the apparatus 1, for example, manufactured via an extruder equipped with a subsequent underwater pelletizer. The bulk material 3 is transported from the storage silo 75 to the loading module 2 of the device 1 by means of a pneumatic suction conveyor via a pneumatic transport pipe 76, as is known from the state of the art.

  In the plant of FIG. 5, the suction fan 64 is used on the one hand for sucking the temperature-adjusting gas induced by the heat exchanger tube of the heat exchanger module 4 together with the bulk material 3 in parallel flow, and on the other hand the air pressure. It is used to supply a carrier gas for suction conveyance in the type conveyance pipe 76.

  In the apparatus 1 of FIG. 5 as well, the bulk material 3 is conveyed by gravity by the heat exchanger module 4, and is not pneumatically conveyed.

  In the apparatus 1 of FIG. 5, the carry-out module 5 is an area connected to the heat exchanger module 4, that is, the taper portion of the carry-out module 5 that is tapered toward the discharge connection portion 17 has the maximum diameter. And has a larger diameter than the other housings 8. Due to this diameter expansion, a free temperature-adjusting gas chamber 25 is generated from the bulk material 3 in a region where the bulk material 3 enters the carry-out module 5. In the embodiment of FIG. 5, the temperature adjusting gas suction pipe 65 comes out of the temperature adjusting gas chamber. The suction pipe 65 branches off at a first branch point 77 on the downstream side of the carry-out module 5. The carrier air portion 78 communicates the branch point 77 with the charging point 79, and the unloading connection portion 17 coming from the unloading module 5 communicates with the suction pipe 65 at the charging point 79. The bypass portion 80 of the suction pipe 65 causes the branch point 77 to communicate with the opening point 81 of the suction pipe 65, and the opening point 81 is located downstream of the charging point 79 in the suction conveyance pipe 82 that continues to the suction pipe 65. Has been placed. The bulk material 3 heat-treated in the apparatus 1 is conveyed to an intermediate conveyance container 83 used as a separator via a suction conveyance pipe 82. In the intermediate conveyance container 83, a filter such as the filter 52 of the separator 51 of the embodiment of FIG.

  A control valve 84 is disposed in the bypass portion 80. The control valve 84 is connected to the filling level sensor 39 in the carry-in module 2 via a signal line 85.

  In the suction pipe 65, a fresh air supply pipe 87 is opened through an opening point 86 in a pipe path between the intermediate transfer container 83 and the suction fan 64. A fresh air control valve 88 is disposed in the fresh air supply pipe 87 upstream of the opening point 86. The fresh air control valve 88 is connected to a filling level sensor 90 via a signal line 89, and the filling level sensor 90 measures the filling level of the bulk material 3 in the housing of the intermediate transfer container 83. The bulk material discharge part of the intermediate transport container 83 is closed by a freely closing closure flap valve 91. The closing flap valve 91 may be pre-biased by, for example, a spring in the closed position shown in FIG.

  The plant of FIG. 5 operates as follows. By operating the suction fan 64, the bulk material 3 is pneumatically transferred from the storage silo 75 to the loading module 2 of the device 1 for cooling or heating the bulk material 3. The bulk material 3 is conveyed from the carry-in module 2 to the carry-out module 5 through the heat exchanger module 4 by gravity. From there, the heat-treated bulk material 3 is similarly transported to the intermediate transport container 83 by the suction transport pipe 82 by the pneumatic suction transport through the charging point 79. When the filling level sensor 90 indicates a certain level of filling level in the intermediate transport container 83, the fresh air control valve 88 is opened. As a result, the negative pressure in the intermediate transport container 83 is lowered and the closing flap valve 91 is opened. As a result, the bulk material 3 after the heat treatment can be supplied to a further processing section as indicated by a directional arrow 92 in FIG. At this time, the gravity of the bulk material 3 in the intermediate transport container 83 exceeds the pre-biasing force in the direction opposite to the closing spring of the closing flap valve 91.

  The suction conveyance from the apparatus 1 to the intermediate conveyance container 83 by the suction conveyance pipe 82 is performed only when the apparatus 1 is sufficiently filled. When the filling level sensor 39 detects that the filling level in the carry-in module 2 has fallen below a predetermined value, the control valve 84 opens, and as a result, the air passes through the charging point 79 and actually only bypasses the bypass pipe 80. It is sucked in through the air and the pneumatic transfer of the bulk material between the apparatus 1 and the intermediate transfer container 83 cannot be performed.

  Thus, in the embodiment of FIG. 5, the suction carrier air is also used as a temperature adjusting gas.

  FIG. 6 shows another embodiment of the device 1 for cooling or heating the bulk material. Components corresponding to those described in connection with FIGS. 1-5 are given the same reference numerals and will not be described again in detail.

  In the embodiment of FIG. 6, the temperature adjusting gas can be selectively guided in parallel flow or counterflow with the bulk material 3 through the heat exchanger tubes of the heat exchanger module 4. A first adjustable shut-off element in the form of a flap valve 93 is arranged in the temperature-adjusting gas path between the fan 19 and the carry-in module 2. The flap valve 93 is located between the first pipe branch point 94 and the second pipe branch point 95 of the temperature control gas pipe network 96. The first pipe branch point 94 is between the gas processing unit 46 and the flap valve 93. The second pipe branch point 95 is located between the flap valve 93 and the opening to the carry-in module 2 of the temperature regulating gas pipe network 96 of the embodiment of FIG.

  Another adjustable shut-off element in the form of a flap valve 97 is in the temperature regulating gas network 96 between the first tube branch point 94 and the third tube branch point 98. The third pipe branch point 98 is located in the temperature control gas pipe network 96 between the outlet from the pipe network to the carry-out module 5 and the separator 99. Between the third tube branch point 98 and the separator 99 is a fourth tube branch point 100. Between the third tube branch point 98 and the fourth tube branch point 100 are other adjustable blocking elements in the form of flap valves 101. Within the temperature regulating gas network 96, there are other adjustable blocking elements in the form of flap valves 102 between the second tube branch point 95 and the fourth tube branch point 100.

  When the temperature adjustment gas is guided through the heat exchanger module 4 in parallel flow with the bulk material, the flap valves 93 and 101 are opened, and the flap valves 97 and 102 are closed. At this time, the temperature adjusting gas flows from the fan 19 through the branch point 94 and the branch point 95 into the carry-in module 2 and from there through the heat exchanger module 4 into the carry-out module 5, from which a chamber not shown is formed. It returns to the temperature control gas pipe network 96 again through the temperature control chamber formed by the apparatus, and flows from there to the separator 99 through the branch point 98 and the flap valve 101. The entrained bulk material fine particles are separated by the filter 52 of the separator 99, and the fine particles are discharged through the rotary blade type separation gate 54. The temperature adjusting gas leaves the separator 99 via a discharge pipe (see arrow 103 in FIG. 6).

  When the temperature adjusting gas is guided to the bulk material 3 through the heat exchanger module 4 in a counter flow, the flap valves 97 and 102 are opened, and the flap valves 93 and 101 are closed. At this time, the temperature adjusting gas flows from the fan 19 through the third branch point 98 to the carry-out module 5, and then flows into the carry-in module 2 in a counterflow with respect to the bulk material 3 via the heat exchanger module 4. It flows to the separator 99 via the branch point 95 and the flap valve 102.

  In order to eliminate clogging in the heat exchanger pipe, the flap valves 93, 97, 101, and 102 are appropriately controlled to open and close, and the temperature adjustment gas is periodically (in a tact manner) in parallel through the heat exchanger pipe. It can be guided in flow and in counterflow. For this reason, the flap valves 93, 97, 101, 102 can be driven by a drive unit (not shown) to be displaced between the valve opening position and the valve closing position, and similarly via a control line (not shown). Connected to the central control unit.

  Next, another embodiment of the apparatus 1 for cooling or heating the bulk material will be described with reference to FIG. Components corresponding to those described in connection with FIGS. 1-6 are given the same reference numerals and will not be described again in detail.

  The apparatus 1 in FIG. 7 is different from the apparatus 1 in FIG. 6 in that the temperature adjustment gas is supplied to the first pipe branching point 94 of the temperature adjustment gas pipe network 96 at a negative pressure. For this purpose, the device 1 of FIG. 7 is connected to a compressed gas network or a compressed air network 104. A pressure reducing valve 105 is disposed in the temperature adjusting gas pipe network 96 on the downstream side of the compressed gas network 104. A gas processing unit 46 is disposed downstream of the pressure reducing valve. In the flow path of the temperature adjusting gas between the gas processing unit 46 and the first pipe branch point 94 on the downstream side, the temperature adjusting gas is adjusted to the branch point 94 and another temperature adjusting gas pipe network 96. A pulsation device 106 is provided for pulsating supply of gas. The pulsating device 106 is a periodic (tact) valve, that is, a valve that opens and closes periodically (in a tact manner). A tact armature can be used when supplying a relatively large amount of gas in a pulsating manner.

  When the pulsating device 106 is used, a pulsating parallel flow or a pulsating counterflow of the temperature adjusting gas is possible with respect to the flow of the bulk material 3 through the heat exchanger tube of the heat exchanger module 4. As an alternative or in addition, by controlling the flap valves 93, 97, 101, 102, the parallel flow through the heat exchanger tubes, as already explained in connection with FIG. Periodic (by tact method) alternation with the counter flow can be performed.

  Next, another embodiment of the apparatus 1 for cooling or heating the bulk material will be described with reference to FIG. Components corresponding to those described in connection with FIGS. 1-7 are given the same reference numerals and will not be described again in detail.

  In the apparatus of FIG. 8, a bulk material bypass pipe 108 is disposed between the carry-in module 2 and a discharge transport pipe 107 disposed on the downstream side of the rotary blade type discharge gate 16 in the bulk material transport path. . In the event that an undesired clogging of the device 1 occurs in the bulk material transfer path from the carry-in module 2 through the heat exchanger module 4, the carry-out module 5 and the rotary vane discharge gate 16, the bulk material 3 is basically Is known from the above-mentioned patent document 2 (German Patent Application Publication No. 2004044586A1) and bypasses the heat exchanger module 4 and the rotary vane type discharge gate 16 and is guided through the bulk material bypass pipe 108. can do.

  Arranged in the bulk material bypass pipe 108 is a throttle element 109 in the form of a cap-shaped throttle 109. Between the throttle element 109 and the opening point 110 of the bulk material bypass pipe 108 to the discharge conveyance pipe 107, a temperature adjusting gas take-out pipe 111 opens to the bulk material bypass pipe 108. The temperature adjustment gas take-out pipe 111 communicates the bulk material bypass pipe 108 with a temperature adjustment gas return pipe such as the temperature adjustment gas return pipe 49 of the embodiment of FIG. The tube cross section of the temperature control gas return tube 111 is several times smaller than the tube cross section of the bulk material bypass pipe 108.

  The temperature adjustment take-out pipe 111 increases the amount of gas for the parallel flow induction of the temperature adjustment gas and the bulk material 3 through the heat exchanger pipe 9. This is because the gas amount of the temperature adjusting gas does not need to flow through the rotary vane type discharge gate 16, and thus the pressure difference of the temperature adjusting gas becomes larger.

  The throttle element 109 ensures that the downstream side of the throttle element 109 in the bulk material bypass pipe 108 has a lower pressure than the upstream side of the throttle element 109. As a result, the temperature adjustment gas flows through the heat exchanger tube 9 in parallel flow with the bulk material 3 from the carry-in module 2 to the carry-out module 5 side by the communication with the temperature adjustment gas take-out pipe 111. Guaranteed.

  In the embodiment of FIG. 8, the supply of the temperature adjusting gas is performed corresponding to the embodiment of FIG.

  Next, another embodiment of the apparatus 1 for cooling or heating the bulk material will be described with reference to FIG. Components corresponding to those described in connection with FIGS. 1-8 are given the same reference numerals and will not be described again in detail.

  In the embodiment of the apparatus 1 of FIG. 9, the difference from the embodiment of FIG. 8 is that the temperature adjustment gas is not supplied to the carry-in module 2 via a fan independent of the supply of the bulk material. Corresponding to the conveyance pipe 76 in the case of the embodiment of FIG. 5, it is performed by a pneumatic conveyance pipe via pneumatic conveyance. The conveyance in this case is pressure feeding or suction conveyance as in the embodiment of FIG.

  In other respects, the embodiment of FIG. 9 corresponds to the embodiment of FIG.

  Next, another embodiment of the apparatus 1 for cooling or heating the bulk material will be described with reference to FIG. Components corresponding to those described in connection with FIGS. 1-9 are given the same reference numerals and will not be described again in detail. Note that FIG. 10 is considerably more schematic than FIGS. 8 and 9.

  In the embodiment of FIG. 10, a bypass control valve 112 is arranged as a throttle element in the bulk material bypass pipe 108. This bypass control valve 112 is connected to a differential pressure sensor 114 via a signal line 113. The differential pressure sensor 114 is connected to the bulk material bypass pipe 108 via measurement lines 115 and 116 on the upstream side and the downstream side of the bypass control valve 112, respectively. The opening width of the control valve 112 is set depending on the differential pressure measured by the differential pressure sensor 114. If the differential pressure is small, the flow rate through the control valve 112 is reduced, for example.

  In the case of the embodiment of FIG. 10, if the compensating tube 111 is not provided, the amount of gap between the rotary impeller and the rotary impeller housing of the rotary vane type discharge gate 16 is correspondingly increased. Undesirably large pressure losses at the discharge gate 16 can be avoided. This point is suggested graphically in FIG.

  Next, various other embodiments of the chamber forming apparatus for generating at least one temperature-controlled gas chamber in the unloading module 5 of the apparatus for cooling or heating the bulk material will be described with reference to FIGS. explain. Components corresponding to those described in connection with FIGS. 1-10 are given the same reference numerals and will not be described again in detail.

  The chamber forming apparatus 117 can be used in place of the chamber forming apparatus 24 of FIG. 1 or the chamber forming apparatus 47 of FIG. The chamber forming apparatus of the embodiment of FIG. 5 may be implemented as illustrated in FIG. 11, for example.

  In the case of the chamber forming device 117, the heat exchanger module opens to the inlet-side upper housing part 119 of the unloading module 5 through the inlet connection part 118 having the same diameter as the housing 8 and connected to the housing. The inlet connection 118 penetrates slightly into the housing part 119 so that the outlet of the inlet connection 118 for the bulk material 3 is deeper than the housing cover 120 of the unloading module 5 in FIG. The outer diameter of the tubular upper housing portion 119 is greater than the outer diameter of the inlet connection 118. The housing portion 119 is connected to the housing portion of the carry-out module 5 that is tapered toward the discharge connection portion 17. Therefore, around the inlet connection 118 protruding into the housing part 119, the ring-shaped temperature regulating gas chamber 25 remains in the housing part 119 of the unloading module 5. Therefore, after the temperature adjusting gas flowing together with the bulk material 3 through the heat exchanger tube 9 of the heat exchanger module 4 flows out from the inlet connection portion 118 into the housing portion 119 (see the directional arrow 121), first the temperature adjusting gas is used. It flows into the chamber 25 and then flows out from the carry-out module 5 through the temperature adjustment gas outlet connection part 122 mounted in the cover 120.

  The embodiment of the chamber forming apparatus of FIG. 11 is particularly suitable for granular bulk materials.

  In the embodiment of FIG. 12, instead of the tubular inlet connection 118 of FIG. 11, a tapered tapered inlet connection 123 is provided that also projects into the housing portion 119 of the unloading module 5. Yes. The outer diameter of the housing part 119 is significantly larger than that of the embodiment of FIG. 11 compared to the outer diameter of the housing 8 of the heat exchanger module 4 corresponding to the maximum diameter of the inlet connection 123. Accordingly, a temperature adjusting gas chamber 25 having a remarkably large volume is generated in the housing portion 119 of the unloading module 5 of FIG.

  In the case of the embodiment of FIG. 12, the outlet connection 122 has a cross-section in the outlet area of the carry-out module 5 compared to FIG. Has been implemented to be significantly larger. According to FIG. 12, this cross section is tapered in a taper shape in the extending direction of the temperature adjusting gas outlet connecting portion 122.

  The chamber forming device 124 of FIG. 12 is particularly suitable for the powdered bulk material 3.

  In the chamber forming apparatus 125 of FIG. 13, the inlet connection portion 126 that can be used instead of the inlet connection portion 123 in the embodiment of FIG. 12 is expanded in a taper shape in the flow direction of the bulk material 3 and the temperature adjusting gas. Yes. A discharge taper portion 127 is disposed in the housing portion 119 of the carry-out module 5 on the downstream side of the inlet connection portion 126 in the flow direction of the bulk material 3 and the temperature adjusting gas. The taper angle of the discharge taper portion 127 is flatter than the taper angle of the inlet connection portion 126. The tip of the discharge tapered portion 127 is on the inlet connection portion 126 side, that is, upward. The discharge taper 127 creates a ring-shaped conveyance path for the bulk material 3 and the temperature adjusting gas exiting from the inlet connection 126. As a result, a bulk material layer distributed over a wide range is forcibly generated on the discharge taper portion 127, thereby facilitating separation of the temperature control gas and the bulk material 3, and the temperature control gas in the housing portion 119. The temperature adjustment gas can be easily transferred into the chamber 25.

  In the temperature regulating gas chamber 25 within the housing portion 119 of the chamber forming device 125, dust particles or particulates 128 are also suggested that are entrained with the temperature regulating gas. The chamber forming device 125 can separate dust particles or fine particles by the temperature adjusting gas outlet connection part 122 in addition to the function of guaranteeing the temperature adjusting gas chamber so that the temperature adjusting gas escapes from the carry-out module 5. It also has the function of making the bulk material visible.

  FIG. 14 is an enlarged view of the chamber forming apparatus 47 of FIGS. 2, 3, 8, and 9.

  The chamber forming apparatus 129 of FIG. 15 has a profile plate 130 that extends through the carry-out module 5 in a direction transverse to the conveying direction of the bulk material 3. As can be seen from FIG. 16 showing the profile plate 130 of FIG. 15 in cross section, the profile plate 130 has a roof shape. This roof-like profile plate 130 ensures that the bulk material 3 is guided laterally along the profile plate 130 and also ensures that the temperature regulating gas chamber 25 is generated inside the cross-section of the profile plate 130. is doing. The temperature adjustment gas outlet connection portion 131 is disposed so as to open to a portion where the profile plate 130 is directly extended from the housing wall 27 of the carry-out module 5, that is, a temperature adjustment gas chamber formed inside the cross section of the profile plate 130. 25 is in fluid connection.

  FIG. 17 is a top view of a cross configuration of two profile plates 132 and 133 that penetrate each other and each have a roof-like cross section like the profile plate 130. In the region where the profile plates 132 and 133 are coupled to the housing wall 27 of the carry-out module 5, there are a total of four temperatures on the extension of the cross section of the profile plates 132 and 133 as in the outlet connection 131 of FIG. A regulating gas outlet connection 131 is arranged. These four outlet connection portions 131 connect the temperature adjusting gas chamber formed on the inner side of the cross section of the pre-plates 132 and 133 to the ring pipe 134. The other outlet connection 135 for the temperature adjusting gas is opened to carry the temperature adjusting gas out of the ring tube 134.

  The configuration of the chamber forming apparatus 136 in FIG. 17 is another modified embodiment of the chamber forming apparatus.
