Definitions
- the invention relates to a device for separating aerosols or particles from gases according to the preamble of independent claim 1.
- a device for an internal combustion engine is known from EP 0 685 635, with which oil or oil mist is separated from the crankcase gases.
- This so-called crankcase ventilation has a flow-through ventilation line, in the course of which at least one oil separator is arranged, from which a return line for separated oil is led to the crankcase.
- the oil separator is an electrostatic precipitator and is designed as a tubular electrostatic precipitator.
- the electrostatic filter consists of a discharge electrode which is arranged in the interior of the tube through which the flow passes, an electrical DC field being generated between the tube wall and the discharge electrode for charging the oil droplets flowing through. These separate on the inside of the flowed tube and form an oil film there. This oil film flows towards the oil pan.
- a disadvantage of this device can be seen in the fact that the corona electrode is in the aerosol flow and there is therefore a risk of contamination of the electrode. This contamination changes the electrostatic conditions and thus the separation effect. Cleaning the electrode is not possible due to the installation conditions.
- An oil separator device in particular for internal combustion engines of motor vehicles, is also known from DE 196 42 218.
- This consists of an oil separator arranged in a housing.
- the oil separating element has a first and a second electrode, each connected to a high-voltage source, both being arranged in the flow path of the oil gas mixture and having different polarities. With this arrangement there is also the risk that dirt particles will accumulate on the electrodes and thus significantly impair the effectiveness of the separator.
- the invention has for its object to provide a device for separating aerosols or particles from gases, which has a high functionality and contamination of the charge generator is avoided. This object is achieved in accordance with the characterizing features of independent claim 1.
- the main advantage of the invention is that the corona electrode is essentially outside the gas flow and thus no particles or liquids can accumulate on the corona electrode.
- the charge generated by the corona electrode is transported via an air or gas volume flow into the area of the gases to be cleaned.
- an inactive, inert gas such as nitrogen.
- Another advantage of the device is that the charge generation is not subject to the constant need to adapt the electric field to varying distances due to the contamination or, if appropriate, burn-up. In the previously known systems, it is necessary to change the electrical field according to the degree of contamination in order to maintain the separation effect. This can be avoided by the structure described.
- the corona electrode is surrounded by an outer electrode.
- the electric field forms between these two electrodes.
- the electrical charge carriers are discharged via an air volume flow between the corona electrode and the outer electrode.
- the separator is a so-called cylinder capacitor.
- This consists of at least two hollow cylinders arranged concentrically to one another.
- the flow housing itself as a capacitor surface.
- a plurality of hollow cylinders arranged one inside the other or also separator plates arranged parallel to one another can be provided.
- a plate capacitor can also be used.
- the design of the separator is arbitrary and can be adapted to the available space.
- Another embodiment of the invention provides for the flow housing to be designed as part of the crankcase of an internal combustion engine. As a result, the aerosol separating device can be integrated into an internal combustion engine and is suitable for separating oil mists from the crankcase gases.
- a further development of the invention also lies in the cleaning of the air volume flow by an upstream filter. This filter ensures that the air flow does not carry any particles that accumulate on the corona electrode.
- a further embodiment of the invention provides that an additional oil separator in the form of a centrifugal force, impact or fiber separator is connected upstream of the electrical separator. This can also serve to increase the efficiency.
- Figure 1 is a schematic representation of a device for separating aerosols or particles from gases.
- the internal combustion engine 10 shown schematically in FIG. 1 is provided with a crankcase 11.
- This housing encloses the cylinder block 19, at least in the upper region, in which the schematically represented cylinders with the corresponding corresponding piston 20 are located.
- the so-called blow-by gas which arises during the work of the internal combustion engine, flows into the cavity 21 between the cylinder block and the crankcase 11 and arrives at a separator 18 according to the arrows 12 and 17.
- the blow-by gas is an aerosol flow, ie an air flow contaminated with liquid.
- the function of the separator 18 is to separate the air flow from the liquid or from the liquid constituents.
- the separator 18 is structurally similar to a cylinder capacitor.
- this separator is connected to a direct voltage source, so that an electric field is formed between the two cylinders.
- a so-called charging unit is provided upstream of the separator. This consists of an ion source or a corona electrode 14 and an outer electrode 13. An electrical voltage between the outer electrode and the corona electrode causes a discharge at the tip 22, i. H. generation of charge carriers. Other designs of the charging unit are conceivable.
- an air volume flow is conducted between the outer electrode and the corona electrode.
- This air volume flow emerges at the tip 22 of the ion source.
- the ions (charge carriers) generated due to the voltage accumulate on the droplets or particles in the immediate vicinity.
- the droplets thus electrically charged are separated in the separator 18 in the electric field.
- the air volume flow shown according to arrow 15 can be cleaned by an appropriate filter system before entering the ion source.
- the filter system is a commercially available particle filter.
- the air volume flow flows in via a slight overpressure. The extraction of the cleaned blow-by gas.
- a suitable vacuum system is used, which is generally known and is not explained in more detail here. Of course, a pump can also be used to generate negative pressure.
- the injection of the charge carriers or the charge carrier stream 16 can vary in accordance with the amount of blow-by gas that is produced. The variation is determined by the degree of separation required.
