Definitions
- the invention relates to an ionization device for air treatment plants with two electrodes, which are connectable to a high voltage source generating an alternating voltage and between which a dielectrically impeded discharge for generating a plasma can be brought about.
- electrostatic filters which are preferably used for the separation of dust and other suspended particles.
- a potential difference or a static electric field is generated between two electrodes.
- Suspended particles entrained in an air flow are ionized or electrically charged in the electric field and subsequently attracted or deposited by the precipitation electrodes of opposite electrical potential.
- the predetermined potential difference must be sufficient to the suspended particles during the flow through the charging device and then deposited.
- electrostatic precipitators are often used as electric dust collector.
- ionization devices are known, for example, for air filter systems and the like, which have two electrodes which are usually spaced apart, between which a plasma can be generated.
- the regularly designed as a plate capacitor electrodes are connected to a high voltage source, so that a
- Potential difference of several KV between the electrodes can be generated.
- particles and larger molecules located between the two electrodes can be at least partially excited or ionized.
- a suitable excitation of the plasma complex molecular compounds which are perceived as odor nuisance can be broken down into individual components which are odorless.
- suitable electrodes are known for example from DE 20 2006 014 800.0.
- the respective dimensions of the electrodes must be sufficiently large depending on the desired filtering or cleaning action to be able to operate on the one hand with an economically appropriate low AC voltage in the range of, for example 1 KV - 10 KV and on the other hand, a sufficient ionization in the To ensure plasma particles flowing through the air.
- the known electrodes are therefore often large-scale and bulky, so that they, for example, in Extractor hoods or industrial filtration systems can be used and used, but not suitable for use in air filter systems in motor vehicles with a very limited space.
- An object of the present invention is therefore considered to design electrodes of the type mentioned so that a comparably effective generation of a dielectrically impeded discharge or a plasma with the least possible space required is possible.
- each electrode has a deformable structure with an electrical conductor, which is coated with a dielectric material and that the two deformable
- Structures are at least partially touching or a sufficiently small distance from each other having fixed to be able to bring about the dielectrically impeded discharge can.
- Investigations by the Applicant have surprisingly revealed that the previously used plate or lattice-shaped rigid conductors, which were regarded as a necessary prerequisite for generating a plasma, are not absolutely necessary and can be formed with deformable structures electrodes, between which a suitable dielectrically impeded discharge can be brought about in order to produce a suitable plasma for the treatment of air.
- Such electrodes which consist essentially of a deformable structure, which is electrically conductively connected to a high voltage source, can be deformed in a simple manner and thereby to different Shaping be adapted.
- the two deformable electrodes which are fixed relative to one another can also be curved, wound or compressed in an irregular or random manner or deformed almost arbitrarily in order, for example, to make better use of a given volume of space through which the air to be treated flows.
- the two deformable structures each have a band or thread-like shape.
- Such structures are simple and inexpensive to produce and allow for a suitable choice of material and depending on the dimensions selected in each case a virtually arbitrary deformation, without causing damage to the deformable structure or a
- Impairment of the function of the electrode must be feared.
- each electrode has a sheathed wire which is plastically deformable.
- Such wires sheathed with a suitable dielectric material are commercially available inexpensively.
- the coated wires can be connected to each other or, for example, intersecting or umwickelnd set and thereby without much effort and without additional design measures have sufficient dimensional stability to permanently in the intended operating conditions and in the given shape, the generation of the desired or to ensure necessary plasma.
- the two deformable structures are interwoven with each other.
- the preferably thread-like deformable structures can be woven together with the known weaving techniques and form a knitted fabric or a fabric with approximately textile mechanical properties.
- the interwoven electrodes have a large number of intersection points arranged at a distance from one another, against which the two deformable structures can touch.
- a suitable alternating voltage By applying a suitable alternating voltage, a potential difference is generated between the two electrodes, so that preferably at the crossing points and in their immediate vicinity a plasma is generated which ionizes particles of the air flow flowing through these areas and larger molecules, particles or liquid droplets into smaller or odorless components Components decomposed.
- the interwoven electrodes expediently form a woven fabric or a textile fabric which, if appropriate, can be multilayered, complexly curved or angled or folded over at the edges and adapted to almost any spatial body shape.
- the deformable structures have a diameter of less than 2 mm. In such dimensions, depending on the material used also significantly less than 1 mm or more than 2 mm, it can be ensured at the same time that at crossings or areas of greatest approximation between the deformable structures sufficient for the respective air treatment plasma can be generated.
- adjacent intersection points of the two deformable structures have a distance of more than 5 mm, preferably of more than 10 mm.
- the dielectric material is a low-carbon material.
- the individual carbon atoms would be released from the composite material so that the dielectric material would be damaged and possibly completely destroyed. This danger does not exist, for example, when using a mineral-ceramic material or when using a silicone resin to the same extent.
- an embodiment of the inventive concept will be explained in more detail, which is shown in the drawing. It shows:
- Fig. 1 is a schematic plan view of a
- An electrode assembly for generating a dielectric barrier discharge or a plasma with two filiform deformable structures, which are each connected to a high voltage source generating an alternating voltage and
- Fig. 2 is a sectional view of the electrode assembly shown in Fig. 1 along the line II-II in Fig. 1st
- the ionization apparatus 1 shown in the figures for air treatment plants has two filiform deformable structures 2, 3, which are each connected to an output 4, 5 of a high voltage source, an alternating voltage with an output voltage within a range of for example 1 to 10 KV with a predetermined Frequency in a range between a few hertz and a few kilohertz or more.
- the two deformable structures 2, 3 each consist of an electrically conductive metal wire 6, which is sheathed with a low-carbon dielectric material 7 or completely insulatively surrounded.
- the diameter of the metal wire 6 is 1-2 mm.
- the thickness of the cladding with the dielectric material 7 is less than 1 mm.
- the two thread-like deformable structures, 2, 3, each forming an electrode are interwoven and form a fabric or fabric with approximately textile properties.
- a plasma is generated upon application of a suitable AC voltage, the entrained in the air flow entrained particles, liquid droplets or larger molecules into individual components and components that are odorless and harmless can be discharged into the environment.
- Investigations have shown that such an electrode arrangement is also advantageously suitable for breaking down volatile organic compounds (VOCs) into individual constituents which are harmless to the environment.
- VOCs volatile organic compounds
- the ionization can expediently in Having flow direction multi-layered fabric, so that by the multiple passage of the air flow through spaced apart fabric layers a total sufficient filtering or cleaning effect can be achieved. Further advantages in the embodiment of the electrodes according to the invention is the possibility of being able to safely operate these electrodes during operation, for example, or to bring them into contact with liquids.
