Definitions
- the invention relates to a centrifugal oil separator according to the preamble of claim 1.
- centrifugal oil separator which is used to separate oil in the ventilation gases of a crankcase of an internal combustion engine.
- the centrifugal oil separator has a rotatably mounted and drivable plate separator in a separator housing, which consists of a plurality of stacked and approximately conical plates which are kept at a distance from one another, as a result of which flow channels are formed between adjacent plates of the plate separator. Linear or punctiform webs can be applied between the plates to guide the flow and to stabilize the plate stack on the top or bottom of the plates.
- the plate separator is flowed through radially from the outside inward by the venting gas, the oil droplets in the venting gas sedimenting on the underside of the plates and, due to the centrifugal forces arising due to the rotating movement of the plate separator and the sloping plate walls, are again thrown radially outwards and via a outlet opening arranged in the bottom of the separator housing can be derived.
- the invention is based on the problem of minimizing the pressure loss in a centrifugal oil separator.
- a rotary element in addition to the plate separator, a rotary element is provided in the housing, which is designed as a compressor wheel and is arranged in the region of an axial end face of the plate separator.
- the gas to be cleaned is fed to the compressor wheel via an inflow opening in the housing, which gas is compressed to an increased pressure by the compressor wheel, the pressure side of the compressor wheel - the downstream side of the compressor wheel - m t being connected to the inflow space of the plate separator or, if appropriate, identical.
- the compressor wheel represents a pressure generator integrated in the centrifugal oil separator, which helps to reduce the pressure loss between the inlet and outlet sides of the oil separator.
- the compressor wheel comprises rotary blades which are connected to one of the front plates of the Plate separators are connected.
- the plate separator is expediently rotatably mounted in the housing and is driven by a drive motor assigned to it, with the rotation of the plate separator also automatically driving the compressor wheel and conveying the supplied gas from the compressor wheel into the inflow space and compressing it to an increased pressure.
- a separate drive for the compressor wheel can be omitted.
- the plate separator can also be arranged in a rotationally fixed manner in the housing of the oil separator; however, a rotatable mounting of the plate separator in the housing, which is independent of the compressor wheel, may also be considered.
- Fig. 2 is a perspective view of a centrifugal oil separator with a compressor wheel designed as a centrifugal pump.
- the centrifugal oil separator 1 shown in FIG. 1 comprises a plate separator 3, which is rotatably mounted in a housing 2 and can be driven by a motor M.
- the plate separator 3 has a plurality of stacked, approximately conical plates 4 which are arranged at a distance from one another and between which flow paths 6 are formed.
- the plate separator 3 is radially surrounded by an inflow space 7, which is formed between a cylindrical inner wall of the housing 2 and the radial outside of the plate separator.
- the plate separator 3 becomes radial via the inflow space 7.
- the gas to be vented flows radially inward through the flow paths 6 between the adjacent plates 4 and is discharged axially as a cleaned gas via an inner, axially extending outflow channel and is discharged from the housing 2. Due to the conical shape of the plates 4, the flow paths 6 between adjacent plates also have an axial component in addition to the radial one. To guide the flow and to stabilize the stack of plates, linear or punctiform webs can be applied between the plates on the top or bottom of the plates.
- a compressor wheel 5 rotatably ⁇ which suitably secured to the front end plate 4' is connected together with the disk separator 3 Umlauft.
- the compressor wheel 5, like the plate separator 3, is also radially surrounded by the inflow space 7.
- Compressor wheel 5 requests exhaust gas supplied via an axial flow opening 9, which flows into a radially inner flow chamber 10, radially from the inside out into flow chamber 7.
- Via the compressor wheel 5, the inflowing vent gas is compressed to a higher pressure, under which the vent gas flows radially inward from the inflow space 7 via the flow paths 6 between the plates 4.
- Oil droplets can sediment in the venting gas on the walls of the plates 4 and flow radially outward into the inflow space 7 due to the inclination of the plates and due to the centrifugal forces generated by the rotation of the plate separator 3.
- the oil droplets which collect and collect at the bottom of the inflow space 7 are discharged from the housing 2 with pressure via the outflow opening 11 due to the relative overpressure prevailing in the inflow space.
- FIG. 2 shows the blades of the compressor wheel 5, which is rotatably mounted in the housing 2 of the oil separator 1.
- the compressor wheel 5 can also be designed and driven independently of the plate separator.
- the plate separator 3 is only hinted at in FIG. 2 and is located in the area axially adjoining the compressor wheel 5.
- centrifugal oil separator is used in particular to separate 01 in ventilation gases from a Kurbeigehause of an internal combustion engine.
- applications from other areas of technology are also possible in which droplet separation from gas flows is to be carried out.
