Definitions
- the invention relates to devices for generating ozone and dielectrics for generating ozone.
- Insulated wall mostly a glass tube prevented.
- Partial breakthrough is a prerequisite for the formation of ozone. It can be shown as a short impulse in the circuit. The measurement of the amount of charge converted for the. Energy requirements in ozone production would be interesting, given the pulse duration - on the order of ns (nano seconds) - and the repetition of similar pulses
- this partition made of material with increased
- Permittivity tested i.e. the upstream capacity in front of the gas route is increased. As a result, the discharges in the gas section become more powerful.
- Ozone producing gas line is in series, probably greater electricity, but does not bring a greater ozone yield, then the reverse route is a suitable measure to improve the ozone yield without the power source with greater current
- the device according to the invention corresponds to this
- the tubes also serve as an oxygen supply or air supply when air is used as the starting material.
- the volume in which the discharge occurs is the gap between the oem tube and the grounded counter electrode. The oxygen flows through this gap very evenly, which is favorable for the desired effect. It is also favorable that the device in the sense of the insulating material
- Electrodes no further than the path through the material. The turning of the tubes cannot therefore be carried out in the direction of the lay.
- Field lines in the insulating material are larger by a factor ⁇ i than in the parallel gas section, which according to the invention is also referred to as the pure gas section.
- the electric field strength in the gap corresponds to that with the tube
- the voltage drop at the tube is small, so that almost all of the voltage at the gas gap is

- Fig. 3 a cross-sectional view of the columnar
- Fig. 4 a cross-sectional view of a substantially
- FIG. 5 a cross-sectional view of the plane
- Fig. 8 a supervision of one for implementation
- honeycomb body suitable for the invention.
- electrical stress in one direction is intended to indicate the direction of a substantial proportion of the field vectors of the electrical equilibrium or alternating field.
- Trobular encompass any cross-section of a hollow column.
- breakdown path denotes the shortest possible distance which is broken through when an electrical insulating material breaks down electrically. As far as distances inside and outside of materials with each other are compared, their length is the physical length and without correction factors.
- Embodiments designate the same reference numerals, the same or equivalent components.
- the metal tube 1 serves both as a high voltage electrode and as a feed tube for the oxygen or air to be ozonized and also as a holder for the
- the Isolierstoff-Rillerchen 2 are the dielectric, which is designed to be puncture-proof because the breakdown path through the pipe in the direction of stress is not shorter than the breakdown path through the air past the pipe.
- the gap 3 between the tube 2 and the counter electrode 4 is the volume in which the discharge converts the oxygen to ozone.
- the counter electrode 4 can
- the plastic wall 5 serves to hold the tube 2 and forms the end of the
- a possible water cooling of the counter electrode 4 is provided in the volume 7. It serves as a metal pipe
- the insulating tubes 2 are puncture-proof
- Dielectric and gas supply line to the gap 3 is formed.
- the reference symbol 3 denotes the gap between the tubes and the counterelectrode 4, in which the conversion of oxygen into ozone takes place.
- the counter electrode which can be cooled if necessary, is designated.
- the plastic wall 5 serves to hold the tube 2 and the completion of the
- Reference 7 denotes a possible cooling device. Detailed description of the first embodiment
- Figure 1a shows a number of insulating tubes 2, which are arranged in parallel. On the one hand, they are in one
- the I solierstof fes of the tubes 2 have no air gap. This can be achieved if a conductive coating is applied to the insulating material, which is galvanically connected to the metal of the pipe.
- the metallic tube 1 serves as a high voltage electrode.
- Tube 2 is a gap 3 with precisely adjustable width compared to the flat counterelectrode 4 - the most favorable results were achieved at 1.5 mm in the test system - in which the discharges take place which partially convert the oxygen to ozone. Further preferred gap widths between
- Dielectric and counter electrode 4 could be between 0.3 and 2 mm.
- the tubes 2 are held in a plastic skin 5, which at the same time
- the dielectric displacement flow is concentrated by solid insulating materials 2 to such an extent that the field strength in the gap 3 is sufficient to generate ozone, and outside the gap 3, i.e. outside of the immediately adjacent
- Counter electrode 4 can be cooled with water 7, which, according to the measurements available, is only necessary if a very large number of tubes are active on this electrode. In principle, the reverse flow of the gas is also possible.
- the electrodes 1, 4 can also be interchanged without impairing their function. However, water cooling is no longer without it
- Puncture resistance is ensured if the high-voltage parts are at a sufficient distance from the grounded parts so that no breakdown occurs in the pure gas section at the highest voltages required.
- Such dimensioning can in each case be determined by experts in this field for a certain embodiment using the teaching of the invention through practical tests.
- the dielectric for concentrating the electrical field lines can be in the form of columns or in the form of honeycomb bodies with breakthroughs through the insulating material, with electrical stress in the axial direction of the pillars or the breakthroughs.
- the oxygen then flows through the columnar tubes or openings and must end up through a narrow gap in which the discharges take place.
- Discharge lines namely pipes or openings, lie parallel with the connected discharge lines.
- insulating tube 8 can be used, which are provided with bores for receiving tubes 2 in a radial arrangement.
- the end faces 9 must be metallized on one side so that the high voltage can be applied here. The other side must have the gap 3 up to the counter electrode 4
- FIG. 3 shows a section through such an ozonizer, in which the ceramic tube 2 in one
- Insulating cylinder 8 are held. This insulating cylinder 8 is also the partition between the distribution space 12 of oxygen and the collecting space 6 for the gas mixture of oxygen and ozone.
- the discharge gap 3 is arranged between the open ceramic tubes 2 and the counter electrode 4. Here the high alternating voltage between the
- Gas mixture can be achieved.
- Embodiment is shown in FIGS. 4, 5 and 6. You can arrange the tube turning 2 in different ways. For example, in rows or double rows with the associated discharge of the gas mixture. A particularly compact arrangement is given if there are 2 more tubes around each tube with a minimal distance from their circumference
- Dielectric 14 depends.
- the counter electrode 4 is proposed according to the invention
- Application can be determined in a simple manner so that when it is minimized, a discharge outside the gap 3 is always avoided and the desired high ozone generation rates are still obtained.
- Gedenelektrode 4 arranged so that a maximum Quantity per unit area can be accommodated, with a constant between tube 2 and bores 13
- the ceramic tubes 2 are in this embodiment
- the discharge gap 3 is between the tube ends and the counter electrode 4
- Drain holes 13 in the counter electrode 4 have the same
- the partition 5 and the holder for the tubes 2 from insulating material which can be deformed by casting, for example from epoxy resin.
- the latter planar arrangement has the advantage, according to the invention, that in larger systems any number of floors can be attached one above the other and that both the distribution space 12 of the oxygen and the collection space 6 of the gas mixture can be combined from 2 floors if the floors alternate in Flow in the opposite direction.
- the voltage supply is also only required for two components, see Fig. 6.
- Fig. 6 shows the scheme of several superimposed planar devices according to the invention, in which the
- Power supply 17, the oxygen supply line 18 and also the collecting container 6 and the derivation of the gas mixture can be combined.
- the tubes 2 are each held in one plane by an insulating wall 5, which also serves as the partition between the two gas spaces 6, 12 forms.
- the discharge gaps 3 lie between the tubes 2 and the counterelectrode 4.
- the gas mixture flows through the bores (not shown) in the counterelectrode 4, which are to be arranged as shown in FIGS. 4 and 5, and from there into the system out.
- These collecting spaces 6 are cooled by the water pipes 7.
- Insulation housing 19 can be round or angular. Breakthroughs are for the oxygen supply line 18 and for
- High voltage supply 17 required. The voltage must be applied to the metallization 16 of the upper flat surfaces
- Ceramic tube 2 are instructed.
- the insulating containers 19 are each closed by a lid on the upper floor.
- honeycomb bodies 20 are also suitable for practical use.
- extrusion presses are used to shape ceramic mass. These extrusion presses or extruders produce "Hubel", which are cylindrical raw bodies from which insulators are formed by turning. Pipes can also be manufactured as raw bodies, e.g. the tubes here in one
- these honeycomb bodies are also a dielectric 14 with a
- the openings can be made round, square, rectangular, hexagonal or in another shape.
- honeycomb bodies 20 can also be made of ceramic masses with higher
- Honeycomb body 20 is expensive. Basically, the problem with larger honeycomb bodies 20 is easier to solve than those with very small holes 21. However, a casting made of insulating material in connection with a sealing layer with round holes over the square openings 21 of the honeycomb body 20 avoids these disadvantages.
- this is easier if only one half (e.g. black fields) of the openings 21 is flowed through, but holes 13 are made in the counterelectrode 4 under the other half (white fields) that are closed which the gas mixture can flow off when it has flowed under the webs.
- a honeycomb body 20 can then replace the tubes 2 shown in FIGS. 4, 5 and 6.
- This concept offers the same advantage when arranging many levels as when using tube 2 as
- a large number of tubes must be arranged in parallel. For this it can be cheaper in terms of price to pass the tubes through a shaped body, for example a cuboid with a
- the energy requirement has a favorable effect if the wall thickness between the holes is kept small.
- the flow through the gaps should be approximately uniform.
- Electrodes extremely small. The capacitive is corresponding
- the energy required per g of ozone is significantly lower than that of conventional systems and hardly any heating
- the discharges according to the invention are not external but internal discharges, since
- the invention further comprises a dielectric for
- the dielectric material can be glass and / or dense at low cost
- Ceramic materials preferably alkali-lime glass and / or borosilicate glass and / or ceramic materials, preferably KER 100 according to DIN 40 685 comprise.
- Dielectric constant ⁇ r reduces the voltage drop across the dielectric, so that even at a lower total voltage, the field strength in the gap is sufficient to generate ozone. This can reduce the effort required for the power supply.
- the effective capacity of the plant increases. The advantages for the respective application must be weighed against each other. The same applies to the length of the tubes and the thickness of the honeycomb body. Short tubes and low honeycomb bodies allow low voltages, but result in a larger system capacity.
