Definitions
- the invention relates to a drying device with at least one receiving space for receiving textiles and desiccant and a corresponding method.
- DE 26 26 887 A1 shows a tumble dryer, is conducted in the heated air via a blower and a heater to a laundry and subsequently removes moisture from the laundry.
- a desiccant container is interposed, so that air laden with moisture gets into the container and the
- Desiccant adsorbs the moisture of the process air.
- the drying agents used are preferably bead-type adsorptive drying agents based on zeolite. Due to the possibility of heat recovery, a favorable efficiency should be achieved.
- From DE 43 38 366 A1 discloses a laundry treatment machine is known, in which the laundry can fall around in an at least approximately horizontally rotatably mounted laundry drum drum movements, which is brought to dry the laundry, this only indirectly via special water-permeable fabric parts with hygroscopic material in touch.
- the hygroscopic material has polyacrylic resin granules which, however, must not touch the damp textile directly to avoid gel-like softening.
- the drying device has at least one receiving space for receiving textiles and drying agent, as well as a vacuum pump for generating a negative pressure in the at least one receiving space. Due to the negative pressure, water evaporates from the textiles, spreads out in the receiving space and is absorbed by the desiccant. Thus, you need to apply no energy for air heating to dry the textiles. In addition, the negative pressure can be maintained even without high expenditure on equipment substantially lossless over a longer period. Also, the textiles do not need to be moved because the negative pressure acts evenly. In addition, the evaporation takes place at a comparatively low temperature. The drying rate depends inter alia on the level of negative pressure.
- the heat of evaporation of the textiles evaporates relatively quickly until a residual quantity freezes.
- the adsorption process is initially stopped, a drying is not possible in this state. If the waiting time is long enough, the thermal equilibrium causes the frozen water to be readjusted to the temperature of its environment and liquefied, but such a process can take a long time to dry completely.
- the drying device further comprises a warm-up device for warming the textiles, preferably a heat radiator, in particular infrared radiator and / or a microwave radiator.
- the microwave radiator is suitably tuned to the desiccant.
- the textiles can still be warmed up to a comparatively low and also easily adjustable energy input so that a freezing of water is avoided, as a result of which the complete drying process can proceed much more quickly.
- the warm-up device can also be switched on time-controlled, z. B. only a predetermined period of time after the beginning of a drying process.
- the drying agent can be removed from the drying agent in a separate operation by heating the water again.
- a fan is also provided for air cooling the desiccant. Since the desiccant and the textiles are interconnected by air, the heat of adsorption dissipated by the fan will also reach the textiles and heat them. Depending on the structure of the dryer and the amount of drying agent and textile then even the heating device can be omitted or need only be switched on at the beginning of drying. This results in a further reduced energy consumption of the dryer.
- At least two interconnected receiving spaces are provided, namely at least a first receiving space for receiving the textiles and a second receiving space for receiving the desiccant. These can preferably be filled separately.
- zeolite as a drying agent, since it is easy to handle, has a high adsorption effect and is easily regenerable.
- FIG. 1 shows a sketch of a drying device in a cross-sectional view.
- the dryer 1 has a first, upper receiving space 2 for receiving textiles 3, and a second, lower receiving space 4 for receiving desiccant 5, in this example zeolite-based.
- the two receiving spaces 2, 4 are connected to each other via a connecting channel 6, which is secured at the upper receiving space 2 with a grate 7.
- the receiving spaces 2, 4 are designed such.
- the upper receiving space 2 has attached to its ceiling an infrared heater 9 for heating the textiles 3.
- the infrared radiator 9 is controlled by a controller not shown), z. B. in the context of a predetermined program sequence.
- the mass of the desiccant 5 here: zeolite
- zeolite to vote on the maximum of the textiles 3 to be adsorbed water. Assuming maximum water loading, for example of 20% zeolite, 2.5 kg of zeolite are necessary for 500 g of water. This amount of water can be extracted from 1 kg of textiles with 50% initial residual moisture.
- the textiles 3 to be dried are brought into the upper receiving space 2.
- the zeolite 5 In the lower receiving space 4, the zeolite 5 must be present, be it that it is already stored there or is being introduced with the textiles 3.
- the two-part receiving space 2,4 is then acted upon by the pump 8 with a negative pressure.
- the zeolite 5 starts to adsorb the water from the laundry 3.
- 9 energy is supplied by means of the infrared radiator. Drying temperature and drying speed can be determined via the power input of the infrared radiator. For example, with a connected load of 1500 W, the described 1 kg of textiles dry in about 15-20 minutes. After completion of the drying of the upper receiving space 2 is opened to remove the textiles 3 again.
- the zeolite container 5 can be removed, for example, from the lower receiving space 4 and brought into the upper receiving space 2. There he can then be heated with the door open 10 to the optimum temperature for desorption, whereby the water held in the zeolite 5 evaporated and discharged through the door 10 into the external environment. For advantageous for a new drying subsequent cooling phase of the zeolite 5 can be brought back into the lower receiving space 4 and there, supported by a blower 11, cooled.
- blower 1 1 can also be used to cool the zeolite under reduced pressure during the textile drying process, whereby the drying of the textile is further accelerated and can possibly be partially or completely drawn onto the infrared radiator 9. Until the next drying of the receiving space 2,4, should be completed airtight as possible, so that the zeolite 5 adsorbs no humidity, z. B. by airtight door seals.
