Definitions

  • the invention relates to a tube furnace with a housing which contains a heat exchanger which has a wall which separates a first volume from a second volume, wherein the second volume is adapted to receive at least one educt and the first volume is adapted to receive a heat transfer fluid , Furthermore, the invention relates to a method for the chemical reaction of educts in a second volume, in which the process space by means of at least one heat transfer medium flowing through a heat transfer fluid heat or removed. Devices and methods of the type mentioned can be used for example for pyrolysis or for the heat treatment of solids.
  • a tube furnace which contains an Archimedes spiral as a heat exchanger. Heat is supplied to the reactants by hot ash is transported in countercurrent through the Archimedes spiral. As a result, the heat remaining in the ash after combustion can be used to heat the tube furnace.
  • the GB 1 440 525 A describes a drying device for flowing materials, this device having, inter alia, balls.
  • the invention is therefore an object of the invention to provide a tube furnace and a method for its application, in which the temperature is better controlled and reliable operation is possible.
  • the invention relates to a tube furnace with a housing containing a heat exchanger.
  • the heat exchanger has a wall which separates a first volume from a second volume.
  • a first, self-contained volume is formed by the boundary wall of the heat exchanger and a second, self-contained volume of the wall or the housing of the tube furnace on the one hand and the outer surface of the heat exchanger on the other hand is limited.
  • This allows a heat transfer between the first volume and the second volume, without the substances or the streams mix or contact each other.
  • heat can be supplied to a reactant located in the tube furnace when the heat transfer fluid is at a higher temperature than the educt. If, in other embodiments of the invention, the reactant reacts exothermically in the tube furnace and thus has a higher temperature than the heat transfer fluid, heat can be removed from the educt or from the process space.
  • the heat carrier fluid contains at least one spherical fluid.
  • a spherical fluid consists of a plurality of balls of predeterminable size and Nature.
  • all balls of the ball fluid may have an identical shape and / or size within the usual tolerances.
  • the balls may have a different size or a size distribution and / or consist of different materials. Since the balls are round in the usual tolerances, they have no sharp edges, so that the abrasive wear is reduced by the heat transfer fluid in the heat exchanger. Furthermore, due to their smooth surface, the balls do not tend to catch or form agglomerates.
  • the spherical fluid can flow through the heat exchanger like a liquid.
  • solid-state spherical fluid can provide heat at a higher temperature level without phase transition in the heat exchanger.
  • the spherical fluid may have a higher heat capacity than a liquid or gaseous heat transfer fluid, so that the mass flow may be reduced.
  • the heat exchanger can be made smaller, so that the tube furnace requires less overall space.
  • the ball fluid further has the advantage that it does not completely fill the heat exchanger or the flow channels.
  • the heat exchanger can optionally also be flowed through by a gaseous heat carrier in order to adapt the temperature of the ball fluid to predefinable setpoint values or to keep it within predefinable setpoint values.
  • the spherical fluid has spheres with a diameter of about 1 mm to about 50 mm. In other embodiments of the invention, the spherical fluid may have spheres having a diameter of about 5 mm to about 50 mm. In still other embodiments of the invention, the spherical fluid may have spheres having a diameter of about 15 mm to about 30 mm.
  • spheres in the stated size range can store enough heat to be able to handle technically manageable mass flows as a heat transfer fluid to be used.
  • spheres in this size range may be multilayered, for example containing a core of a first material and a cladding of a second material.
  • the first and second materials may each be metals or alloys. This allows, for example, to provide a core with high heat capacity and / or high melting temperature with a coating which is chemically inert and / or has catalytic properties.
  • the melting temperature of the cladding may be higher than the melting temperature of the core.
  • the core may be a phase change material or a latent heat storage, which can provide a comparatively large amount of heat at a constant temperature at its melting temperature.
  • the balls of the spherical fluid may comprise at least one chemical element having atomic numbers from 3 to 6 or atomic numbers from 11 to 14 or atomic numbers from 19 to 34 or ordinal numbers from 37 to 52 or atomic numbers from 55 to 84 or with atomic numbers from 87 to 116 included.
  • the balls of the spherical fluid may contain or consist of at least one chemical element of atomic number 13 or atomic numbers from 21 to 30 or from 39 to 48 or from 57 to 80 or from 89 to 112.
  • the balls of the spherical fluid may contain or consist of at least copper and / or iron and / or aluminum and / or a ceramic.
  • the spheres may contain or consist of a transition metal.
  • Such balls may be characterized by high thermal conductivity and / or high heat capacity, so that a correspondingly large amount of heat can be added to the educts located in the process chamber of the tube furnace or removed from them.
  • the spherical fluid through the wall of the Heat exchanger is separated from the educts, unwanted side reactions are avoided, which can occur upon contact of the balls with the starting materials.
  • the housing of the tube furnace may have a substantially cylindrical cross section and the heat exchanger may include a multi-flight screw conveyor.
  • the auger in this case contains a wall which separates an inner screw as the first volume of an outer screw as the second volume, wherein a screw for receiving the at least one educt is set up and the other screw for receiving the heat transfer fluid is set up.
  • the screw conveyor allows the simultaneous transport of the educt or the resulting product through the tube furnace as well as the transport of the heat transfer fluid.
  • the screw conveyor can also effect thorough mixing of the educts so that the reaction proceeds more uniformly.
  • the educts or the heat transfer fluid can be transported in co-current through the tube furnace, ie the material flow and the heat transfer fluid enter at one end and at the other end.
  • the transport can take place in countercurrent, ie, the inlet side of a material flow corresponds to the outlet side of the heat transfer fluid.
  • the auger may have an axis which carries the flights and about which the auger is rotatable during operation of the kiln. This avoids that the educts or products fall through the free middle part of the screw conveyor through and thereby be transported unevenly through the tube furnace.
  • drive means can be flanged particularly easily to the axis to set the screw conveyor in rotation.
  • the axis may be hollow to allow for recirculation of the spherical fluid.
  • the flow and the return of the heat transfer fluid can be done on one side of the tube furnace, so that the tube furnace is easier to operate.
  • the multi-flight auger may be a sequential auger having a plurality of different longitudinal sections.
  • a plurality of longitudinal sections may be interconnected by a single shaft.
  • different longitudinal sections can have different drive means, so that the rotational speed and / or the drive torque of different longitudinal sections can be controlled independently of one another.
  • different longitudinal sections of the screw conveyor may have a different pitch and / or a different cross section, so that the mass flow and / or the area available for heat transfer are different in different longitudinal sections.
  • the self-adjusting temperature and / or the amount of heat transferred to the respective application can be adjusted. This also makes it possible to produce an intermediate product and an end product in different longitudinal sections of the tube furnace or the screw conveyor, if this in a first longitudinal section produced product is converted as starting material in a second longitudinal section.
  • the tube furnace further includes a recuperator, in which the spherical fluid is brought into contact with a gaseous heat carrier.
  • the gaseous heat carrier allows the heating of the ball fluid before it enters the supply line of the heat exchanger or screw conveyor.
  • the ball fluid leaves the tube furnace via a return and is then returned to the recuperator to recover heat from a hot gas stream, such as a flue gas stream formed during combustion. If the balls are provided with a catalytically active coating, they can be used simultaneously for flue gas detoxification.
  • the recuperator can be used to transfer the heat from the spherical fluid to a gaseous heat carrier and thereby dissipate it into the environment.
  • the recuperator may also include a screw conveyor. This allows the simultaneous cooling or heating of the spherical fluid and its promotion by the recuperator or the promotion of the return of the heat exchanger to the flow of the heat exchanger of the tube furnace.
  • the tube furnace may further include a heater, with which a heat flow through the wall of the cylindrical housing can be generated.
  • a heat flow through the outer wall can be provided or a cooling, ie a heat transfer through the wall of the cylindrical housing, can be prevented or reduced. This allows on the one hand a more accurate temperature control inside the tube furnace or the supply of a higher amount of heat to bring a large mass flow of educts quickly to a predetermined target temperature or to bring the educts to a higher temperature level.
  • the heat exchanger of the tube furnace in addition to the ball fluid a further gaseous heat transfer medium can be supplied.
  • a further gaseous heat transfer medium can be supplied.
  • This allows, for example, a post-heating of the spherical fluid when it cools on initial contact with the still cold educt. Since the supply of a gaseous heat carrier can be quickly absorbed or interrupted, this can also serve to make the control of the temperature prevailing in the tube furnace or to reduce the temperature fluctuations occurring during the control.
  • a base heat flow is supplied by the spherical fluid and additional thermal energy is provided to control the temperature across the gaseous heat transfer medium. This possibility characterizes the tube furnace according to the invention, since liquid heat carriers or the ash particles known from the prior art can not be combined with an additional gas stream.
  • the tube furnace 1 comprises a housing 10 with a wall 101.
  • the housing 10 has at least one approximately circular inner cross section, so that the interior has the shape of a circular cylinder.

  • the housing 10 has a first end 11 and a second end 12. At the first end 11 is the flow of heat transfer fluid and the second end 12 is the return of the heat transfer fluid. Adjacent to the first end 11, the filling opening 15 is arranged for educts to be processed. These can be supplied to the interior of the housing 10 in particular as a solid, but alternatively also in gaseous or liquid form. Adjacent to the second end 12 is an outlet 16 for gaseous reaction products and an outlet 17 for solid or liquid reaction products. Both the heat transfer fluid and the reactants to be reacted are conveyed by a screw conveyor 2 from the first end 11 to the second end 12 of the tube furnace 1. Since the screw conveyor 2 is a multi-start screw conveyor, only heat transfer takes place, but no mass transfer between the heat transfer fluid and the reactants to be reacted.
  • FIG. 2 shows, it is in the screw conveyor 2 to a multi-start screw conveyor, in which a first volume 21 and a second volume 22 by a wall 23 are separated from each other.
  • the second volume 22 is directly accessible via the filling opening 15.

  • the screw conveyor 2 rotates, wherein the educts are transported in the second volume 22 and a heat transfer fluid in the first volume 21 is transported.
  • This allows a heat transfer via the wall 23, so that the educts in the second volume 22 are either heated or cooled, depending on whether the supplied via the opening 25 heat transfer fluid has a higher or lower temperature. Since the available surface of the wall 23 of the screw conveyor 2 is larger than the wall 101 of the housing 10, a significantly larger heat flow per unit time can be transmitted than would be possible with pure heating or cooling of the housing 10.
  • an axis 24 is further seen, which is hollow and has an opening 241 on its front side.
  • the interior of the hollow axle 24 may optionally be used to transport the heat transfer fluid, for example, to recirculate the fluid from the second end 12 to the first end 11.
  • a recuperator 3 which also has an approximately tubular housing 30 with a conveyor screw 35 disposed therein.
  • the second end 32 of the recuperator 3 is arranged lower than the second end 12 of the housing 10. Accordingly, the first end 31 of the recuperator 3 is arranged higher than the first end 11 of the housing 10.
  • the recuperator is not only the supply or discharge thermal energy in the heat transfer fluid, but also the transport of the heat transfer fluid from the return to the flow of the tube furnace first
  • FIG. 3 Exemplary is in FIG. 3 the transition region at the first end 11 of the housing 10 is shown. This has a reservoir or a template for the heat transfer fluid.
  • the the Recuperator 3 leaving the first end 1 balls of the spherical fluid fall from the first end 31 of the recuperator 3 down and are collected by the reservoir at the first end 11 of the housing 10.
  • the opening 25 is periodically immersed in the template and takes on a plurality of balls of the spherical fluid. These are subsequently conveyed through the first volume 21 of the screw conveyor 2 to the second end 12 of the tube furnace 1.
  • the balls of the spherical fluid leave the conveyor screw and are supplied in an analogous manner to the recuperator 3 via its second end 32. This allows a cyclic circulation of the ball fluid used as heat transfer fluid.
  • the spherical fluid can be heated or cooled, so that it passes with a predeterminable temperature in the flow at the first end 11 of the tube furnace 1.
  • the required amount of heat can be introduced specifically into the reactant educts.
  • the degree of filling of the first volume 21 can be matched to the degree of filling of the second volume 22.
  • Balls of at least one metal, a ceramic or a salt may also be solid at higher temperatures, for example 150 to 900 ° C or between about 250 and 700 ° C. As a result, heat can be provided at a higher temperature level than, for example, with water or oil as a heat transfer fluid.
  • FIG. 4 shows an alternative embodiment for supplying the heat transfer fluid. How FIG. 4 shows, this embodiment also uses within the tube furnace 1, a multi-speed screw conveyor, in which a first volume 21 and a second volume 22 by a wall 23 are separated from each other. The first volume 21 is above the hollow axis 24 accessible. In order to allow the heat transfer fluid access to the first volume 21, located at the end of the axis 24, which is hollow, an opening.
