Definitions

  • the present invention relates to oil mist separator of an internal combustion engine, which are designed as a centrifugal separator with a rotor arranged in a housing in the form of a stack of plates and with a radially outwardly surrounding the rotor, extending in the axial direction of the rotor gas guide ring.
  • Such a Tellerstapelseparator is from the patent DE 103 38 770 B4 known, wherein a plurality of axially arranged plates form a rotor and rotate together and thus pressed due to the resulting centrifugal forces, for example, oil droplets to the outside. There they meet a substantially cylindrical gas guide ring, which surrounds the rotor radially on the outside. This basket is rotatably connected to the rotor, so that the basket rotates with the plates.
  • the object of the present invention is to provide oil mist separators of the type mentioned in the introduction, which have a simple structural design with improved separation efficiency.
  • a first solution of the problem succeeds according to the invention by ⁇ lnebelabscheider of the aforementioned type, which is characterized in that the gas guide ring is not formed co-rotating relative to the rotor.
  • Such a gas guide ring can be produced in a simple manner so that the desired functionalities are fulfilled.
  • the gas guide ring may be formed fixed, for example, by being firmly connected to the surrounding housing of the centrifugal separator, or it may also be designed to be movable relative to this housing, but it does not rotate with the rotor.
  • the advantage of the invention is that the ⁇ lnebelabscheider for internal combustion engines has a simple structure and is better deposited by the relative to the rotating rotor not co-rotating gas guide ring oil from the crankcase ventilation gas.
  • the gas guide ring is movable in the axial direction of the rotor relative to the rotor and the housing, wherein the cross section of a clean gas passage between the rotor and the gas guide ring is variable by this movement.
  • a size-variable gap is formed between the gas guide ring and the rotor.
  • the cross section of the clean gas passage is changeable in the sense that the movement of the gas guide ring a smaller clean gas volume flow, the cross section of the clean gas passage is smaller and with a larger clean gas volume flow, the cross section of the clean gas passage is greater.
  • the axial movement of the gas guide ring can be generated solely by a flow of the clean gas. If a slight overpressure prevails in the rotor, then the gas guide ring can be slightly raised in the axial direction by a gas flow flowing axially on the outside in order to increase the gap until a pressure equalization has been established. With decreasing volume flow, the gas guide ring automatically drops again and the gap size is reduced.
  • an upper edge is designed to be bent radially inwardly on this expediently.
  • this can at its upper edge, for example. Bent in an L-shape so as to redirect and direct the gas flow.
  • this upper edge can also be formed cranked, that is, e.g. two 90 - have deflections.
  • this is preferably acted upon by a biasing force which acts in the direction of a reduction of the cross section of the clean gas passage.
  • the force acting on the Gasleitring biasing force can be generated by gravity or by spring force.
  • At least one oil drain trough is preferably formed on the inner peripheral side on or in the gas guide ring. Due to this oil drainage channel, the oil impinging on the gas guide ring due to the centrifugal forces is discharged downwards and can no longer be removed from the clean gas flow at the top.
  • the at least one ⁇ labelitrinne runs along at least one helical line, which points in the direction of rotation of the rotor facing down.
  • the swirl of the gas flow thus supports the oil removal.
  • oil drain trough can support oil separation through impingement and flow deflection.
  • the at least one ⁇ labelitrinne is formed by a cross-sectionally L-shaped or U-shaped profile, with an open side of ⁇ labelitrinne facing down.
  • the oil drain trough is stable and contributes to the stability of the gas guide ring.
  • a favorable injection molding production in this design is possible. Inside this ⁇ labelitrinne the oil is largely protected against entrainment by the rotating gas flow.
  • the gas guide ring can form a closed, perforation-free surface.
  • the gas guide ring may then be e.g. be formed by a one-piece hollow cylinder made of plastic or metal.
  • the gas guide ring may form a perforated or porous surface to receive oil therein.
  • the gas guide ring may be formed by a hollow-cylindrical lattice or sieve or filter material body.
  • the at least one ⁇ labelitrinne is advantageously molded onto the gas guide ring.
  • At least one support ring preferably two axially spaced apart and circumferentially circumferential support rings, is molded onto the gas guide ring except the at least one ⁇ labelitrinne /.
  • a plurality of oil drainage channels be provided on the gas guide ring over its inner circumference and that an upper edge of the gas guide ring has oil scuttle sections radially inward which are open axially downwards and between two adjacent ⁇ lableitrinnen run into this or one of these passing.
  • the lattice or screen or filter material body forming the gas guide ring consists of a non-self-supporting element made of woven or knitted fabric or knitted or knitted fabric, preferably of textile material, or of open-cell foam, each with an integrated support body, or a self-supporting element of a woven or knitted fabric or scrim or knit, preferably of metallic material, or of sintered material.
  • the grid or sieve or filter body forming the gas guide ring has a mesh or pore size between 10 and 300 ⁇ m.
  • an oil discharge annulus be kept free between an outer circumferential surface of the gas guide ring and an inner circumferential surface of the housing.
  • a deflection ring is attached or formed, which points against a present gas flow direction in the interior of the housing. Due to the deflection ring, the gas flow is forced to a sharp deflection, which can not follow the oil particles. The oil particles catch rather radially outside of the deflection ring and can be discharged from there down.
  • two separate annular spaces are formed in the housing between the inner peripheral surface of the housing and the rotor.
  • this is a first annular space between the rotor and the gas guide ring, through which essentially the clean gas is discharged, which does not or hardly passes through the gas guide ring to the outside.
  • a second annulus is formed between the gas guide ring and the surrounding inner peripheral surface of the housing, through which the oil is discharged.
  • a labyrinth seal can be formed between a housing wall of the separator and the gas guide ring, which substantially inhibits the passage of a gas flow, so that this second, outer annular space is kept free of turbulence.
  • a second solution of the object is achieved according to the invention with an oil mist separator of the type mentioned, which is characterized in that the gas guide ring is formed with the rotor co-rotating and forms a perforated or porous surface.
  • the gas guide ring is arranged around the rotor such that the gas guide ring forms a second annular space between its inner circumferential surface and the outer periphery of the plate stack and a second annular space between its outer peripheral surface and an inner peripheral surface of the housing.
  • the gas guide ring is e.g. formed by a hollow cylindrical grid or screen body.
  • the gas guide ring may be formed by a hollow cylindrical body or with lamellae.
  • the slats can act like a fan.
  • the slats may be made of metal and / or plastic, for example, and are preferably designed exchangeable to damaged slats to replace.
  • several lamellae could each be clipped together on the end, in order to obtain a simple production.
  • the lamellae may extend substantially parallel to the axial direction of the rotor.
  • the lamellae are arranged slightly inclined inwards towards the top.
  • the slats are preferably inclined obliquely outwards.
  • the hollow cylindrical body forming the gas guide ring has a first, radially inner body part with lamellae arranged in a first orientation and a second, radially outer body part with lamellae arranged in a second orientation. As a result, the separation effect can be further increased.
  • a labyrinth seal is arranged between the housing and the upper edge region of the co-rotating with the rotor gas guide ring.

  • entrained oil particles are deposited on the plates 20 as a result of centrifugal force action.
  • the separated oil flows radially outwards on the underside of the plate and is thrown off radially outwards.
