  • nozzles which water droplets at a rate and a droplet size that ensure complete evaporation over a short path length. For this it is possible to adjust the position of the nozzles so that those emerging from the nozzles Water droplets have essentially the same speed after a short distance like the process gas flow.
  • the process gas flow for example at the gas inlet has a speed of 15 to 45 m / s, preferably a diffuser angle of 10 ° to 40 °, in particular 25 ° to 35 °, preferably 30 °.
  • a process gas velocity should be in the boiler of 2-10 m / s to minimize the length of the equipment.
  • the one out Water spray emerging from the nozzles should have a droplet size ⁇ 250 ⁇ m, in particular ⁇ 100 ⁇ m.
  • the atomizing nozzles or two-substance nozzles are preferably arranged in such a way that that their spray areas essentially do not overlap to form again to prevent larger droplets and make optimal use of the device cross-section without droplets touching the wall of the apparatus.

  • the cross section of the device can with the Cross section of the tobacco dryer be identical or different from that.
  • Possible Cross sections of the device or tobacco dryer with which the device is used are rectangular, in particular square, circular, or all shapes in between such as oval, elliptical or in the form of an elongated hole.
  • the device has four to twelve, in particular six to ten and preferably eight nozzles, which are essentially annular between the Middle section and the end section of the diffuser at the same angular distance from each other are arranged, the nozzles preferably having a spray jacket angle of 15 ° to 30 °, in particular 20 ° to 25 ° and preferably 22 °.
  • the water throughput of the nozzles can 150 to 500 kg / h, preferably 200 to 300 kg / h.
  • the invention further relates to an evaporation unit for introducing water into the Process gas flow from a tobacco dryer, with a boiler through which there is a flow Atomizing nozzles introduced water completely evaporates in contact with the process gas becomes.
  • a boiler through which there is a flow Atomizing nozzles introduced water completely evaporates in contact with the process gas becomes.
  • Parameters also specifically in the case of the evaporation unit according to the invention will be realized. This applies in particular to the shape of the boiler or the flow through Evaporation unit and the arrangement and flow of the nozzles.
  • this evaporation unit or, more generally, the boiler through which it flows and in particular the steam generating chamber is constructed in modular longitudinal sections can be, which can preferably be connected to one another via flanges.
  • the length of the evaporation unit is adjusted so that it is always ensured that the droplets in the hot process gas evaporate before they leave the evaporation unit.
  • this can also be done by setting the overall length for the evaporation unit can be achieved, but preferably over corresponding to be installed with flanges Intermediate pieces, so that also an adaptation to a possibly desired one Nozzle change is possible.
  • FIG. 1 and 2 is a schematic cross section and a longitudinal section Evaporation unit according to the invention shown.
  • hot process gas for example from a heat exchanger system comes.
  • a flue gas heat exchanger which is supplied with hot gas from a burner, indirectly heats the process gas.
  • a process gas stream 24 occurs after being heated in the heat exchanger system Gas inlet 2 of the evaporation unit according to the invention.
  • Gas inlet 2 of the evaporation unit Connects to gas inlet 2 a diffuser 4, on the circumference of which two-substance nozzles 6 are arranged, with which water can be injected into the evaporation unit 1.
  • the distribution of the Nozzles 6 can be seen in FIG. 1, there are eight nozzles, each with an angular distance of 45 ° intended.
  • FIG. 1 there is also the spray projection surface with the reference number 7 drawn in each nozzle, and you can see here that these projection surfaces do not overlap.
  • the steam generating chamber 8 connects to the diffuser 4 with the nozzles 6, which is so here is referred to because the water injected from the nozzles 6 in this area Converts steam, which then forms part of the process gas.
  • the chamber 8 is modular constructed, and the longitudinal sections 8a and 8b are shown in Figure 2, which over the flanges 12 and 14 are integrated. With this modular construction, the chamber 8 can be made as desired lengthen or shorten if this is - possibly when using others Nozzles - should be required.
  • the chamber 8 is followed by the confuser 16, which is then followed by the gas outlet 18.
  • the process gas heated in the heat exchanger system flows through the evaporation unit 1 and is enriched with evaporating water via the nozzles 6, so that it is present at the outlet 18 as a homogeneous flow without droplets into which the cut tobacco can be introduced without the risk of clumping due to water accumulation consists.
  • the process gas temperature can be regulated and thus also the final tobacco moisture can be set, and very quickly and immediately.
  • a so-called "dummy load" can be a Load for the dryer can be set by adding water or steam to the process gas, which prevents the dryer from overheating even if there are interruptions in production temporarily no tobacco entry.
  • the surface created is until ultimately crucial to achieve the thermodynamic equilibrium Significance for a fast evaporation process. That is why generation a fine spray is an important prerequisite for successful evaporation.
  • the so-called two-component nozzle is therefore particularly useful for solving this task Question because this type of nebulization unlike the simpler single-component nozzles average diameters of less than 100 ⁇ m.
  • Two-substance nozzles basically have one limited throughput at approximately 500 kg / h with the required droplet sizes of ⁇ 100 microns. Therefore, several nozzles are advantageous for larger water flow rates.
  • the evaporation time is a quadratic function of the Droplet diameter.
  • Another size that affects the necessary evaporation time has the so-called relative speed of drying gas / droplets. With small ones Particle diameters, the relative speed after a short particle flight becomes negligible; so that no influence of this size can be observed.
  • the particle trajectories (trajectories) of the droplets are determined by the size, the spray angle as well as determined by the initial speed.
  • 3 and 4 are the tracks approximated for particles with 50 ⁇ m and 100 ⁇ m.
  • the end of the particle track means complete evaporation. It is easy to see that smaller particles do after short flight times (container lengths) completely in the gaseous state switch.
  • the drying gas flow acts as a kind of burning glass.
  • reducing the space spread of the spray jacket can result in large particle space concentrations, those for the incomplete utilization of the energy content of the drying gas stream to lead. For this reason too, it is advantageous to use several nozzles for uniformity to use the room concentration across the cross-section. With accordingly adapted construction and design, however, a single nozzle could also suffice to Example of a circumferential annular gap nozzle.
  • the optimal evaporation of water depends on many factors. in the In particular, these are the water droplet size, the gas temperature and depending on it the residence time of the droplets in the hot gas stream.
  • the gas temperature is here Case "current dryer” in principle set, since it depends on the tobacco drying process is. Under the boundary condition of the fixed gas temperature, the task to produce droplets as small as possible by means of suitable nozzles and then to produce these droplets give enough time to evaporate.
  • the main criterion for the Residence time in the evaporator 1 is the flight speed of the drops.
  • the drop speed and accordingly the gas velocity (approximately the same velocity for very small droplets like the gas ⁇ low slip) be low.
  • the gas velocities in hot gas pipes are usually between 20 to 40 m / s (in the present case between 20 to 30 m / s)
  • the gas velocity in the range should be between approx. 2 to 10 m / s, in terms of evaporation and size to achieve the optimal design of the container.
  • the cylindrical length of chamber 8 could be between 0.8 and 2 m in the experimental setup can be varied so as to influence the residence time of the droplets in the hot gas stream investigate.
  • the assessment of the complete evaporation of the drops was carried out using a Apparatus and metrological relatively simple structure carried out. So was in the direction of flow a baffle plate package directly after chamber 8 in gas outlet 18 (diameter 700 mm) (not shown) installed in which the non-evaporated water drops through the the sharp centrifugal forces occurring are separated.
  • the baffle plate packs were designed in such a way that the separated water in the direction of a sump runs and is enriched there. There were small spots in this tub in several places Temperature sensors (PT 100) installed.
  • the temperatures determine if there is water in the tub. So in the event that the temperature sensors are covered by water, the measured temperature by the cooling effect of the water (evaporative cooling) approximately the so-called cooling surface limit temperature of the phase mixture water / hot air. This temperature is in the cases examined here (Normal pressure and water vapor / air mixture) always below 100 ° C and differs accordingly clearly from the hot gas temperatures in the area of the baffle plate package between approx. 120 ° C to 200 ° C. In the event that no water accumulates in the tub the temperature measured there corresponds to the hot gas temperature. The tub is in the test set-up so that at the start of a test this is done using a Swivel device can be easily emptied.
  • Each of the eight nozzles 6 has a water throughput of 250 kg / h.
  • the propellant for the nozzles 6 is saturated steam: the use of compressed air is in principle also possible.
  • the mass flow is uniformly applied to the nozzles.
  • the drop spectrum consists of particles with a diameter of less than 100 ⁇ m.
  • the measured gas and separator sump temperature is in the range of the complete Evaporation.
  • the chamber length and the angle of the nozzle positioning can have an important impact to have complete evaporation.
