Definitions
- the invention relates to a device for removing particles from a flowing gaseous medium containing the particles.
- DE 10 2004 010 583 A1 discloses an oil separator for separating oil from a flowing medium with a labyrinth-type flow guide formed essentially by baffles. At least one of the baffles is deformable rubber-like at least in a partial region. Furthermore, said oil separator is formed as an integral part of a cylinder head cover of an internal combustion engine.
- a device for removing particles from a flowing gaseous medium containing the particles comprises the following features:
- a channel for guiding the medium, - in a first region of the channel boundary is a to a pole of a
- High-voltage DC source connectable corona charging electrode arranged, and in a second region of the channel boundary opposite the first region, a counter electrode is arranged.
- the invention is based on the finding that the device described above according to claim 1 in an unexpected manner, a nearly 100% removal of the particles while only consuming an electrical power of about 10 watts allows.
- the removal of the particles takes place without appreciable pressure losses of the flowing gaseous medium, which is particularly advantageous when used for oil separation from biofwaste gases of an internal combustion engine.
- the like can not be achieved with hitherto known, purpose-built devices comprising cyclones, gravimetric separators, filters, other electrostatic solutions, etc.
- the high degree of removal is essentially achieved in that said corona charging electrode is used, wherein in the electric field from the counterelectrode to the corona charging electrode in the sense of a hard corona charging a plasma channel is formed, with which charge, namely electrons are transported from the particles to the corona charging electrode.
- the thus-influenced particles are attracted to the counterelectrode by a short path and, where the particles are liquid particles, adhere adhesively, forming a film of liquid.
- the counter electrode and / or at least parts of the channel are, for example, by an inclined position such that the liquid precipitating on the counterelectrode during operation of the device is conducted away from the counterelectrode into a predefinable target region.
- the corona charging electrode comprises projections formed as tips, for example, which are arranged in such a way that they do not project directly into the flowing medium and that their paraboloid-shaped zones of influence cover as completely as possible the channel cross-section through which the flowing medium flows. There must therefore be no free space between the zones of influence of the individual extensions or tips. So that the tips do not protrude directly into the flowing medium, the corona charging electrode, comprising the tips, is arranged, for example, in a bulge of the cavity.
- the electrode region of the device is preceded by a pre-separator, through which the flowing medium is passed, wherein the pre-separator typically comprises at least one baffle plate or a gap with drip edge.
- the device is designed as an integral part of a crankshaft cover or a cylinder head cover of an internal combustion engine.
- the fact that the device is formed comparatively compact and small volume, housing in the cylinder head cover is easily possible, which in turn particularly free spaces for other components, for example in the engine compartment of a motor vehicle, creates.
- the device according to the invention is not limited to use as an oil separator for blow-by gases, but can be used for any form of gas purification.
- the device according to the invention can also be used universally as non-contact seal and / or also be used for gas purification with clean room claims.
- the figure shows as an embodiment of the invention in the form of a schematic diagram of a device for separating oil particles from a flowing gaseous medium 2, comprising a blow-by gas of an internal combustion engine.
- the device comprises a pre-separator 8, through which the flowing medium 2 is first passed.
- the pre-separator 8 is typically designed as a baffle plate or gap with drip edge.
- the flowing medium 2 is introduced into a relative to the horizontal inclined channel 10, which has approximately a rectangular cross-section.
- the flowing medium 2 with the oil particles not deposited by the preseparator 8 passes through an electrode region arranged within the channel 10.
- Said electrode region in this case comprises a corona charging electrode 12, which extends perpendicular to the plane of the drawing substantially over the entire width of the channel 10.
- the corona charging electrode 12 in this case comprises a plurality of tips 14, which are arranged in said direction perpendicular to the plane of the drawing next to or behind each other.
- the tips 14 are furthermore arranged in such a way that their zones of influence, paraboloidal with respect to the oil particles, cover as completely as possible the channel cross-section through which the medium 2 flows.
- the tips 14 are arranged so that they are not directly in the Projecting medium current, including the corona charging electrode 12 is arranged with their tips 14 in a bulge of the channel 10.
- the corona charging electrode 12 is connected to a positive pole 18 of a high voltage DC source.
- the high voltage is preferably selected in a range between about 3 to 12 kV.
- the corona charging electrode 12 opposite a arranged for example as a metal plate counter electrode 16 is arranged, which is grounded accordingly. Similar to the corona charging electrode 12, the counterelectrode 16 extend perpendicular to the plane of the drawing substantially over the entire width of the channel 10 and may be formed in the flow direction over an extension of the corona charging electrode 12.
- the oil particles still contained in the medium flow are thereby influenzated, so that they can be contacted at short intervals
- the device is integrated in particular in a crankshaft cover or a cylinder head cover of a diesel internal combustion engine of a truck.
