Definitions
- the invention relates to a cleaning device for Separating particles from a gas stream, in particular for oil separation systems in internal combustion engines.
- crankcase ventilation compensate It is known to overpressure in internal combustion engines in a crankcase through a so-called crankcase ventilation compensate. Because the given Crankcase gases at very high concentrations Can not have hydrocarbons without more are released into the surrounding atmosphere, but are in the intake tract of the internal combustion engine directed to the combustion chamber from there to become. So as not to burn the negative to influence, however, it is necessary with this so-called blowby gas entrained oil an oil separator system.
- the blowby gas is created using a vacuum source sucked out of the crankcase and via a a cleaning device having a filter element guided.
- a vacuum source sucked out of the crankcase and via a a cleaning device having a filter element guided.
- Oil mist separated by the filter element becomes.
- the separated oil is over a Diverter a collecting area of the internal combustion engine fed. That cleaned of the oil Blowby gas is fed to the vacuum source, which usually from a suction of the Internal combustion engine is formed.
- From DE-C-43 13 52 is an oil separator for compressed gases known in the coaxially arranged screens are provided, which are successively by the Compressed gas can flow through.
- From FR-A is 2 375 448 a cleaning device for separating particles known from a guided gas stream, in which the gas flow through a filter element made of steel wool is led.
- the cleaning device according to the invention particularly has the advantage of a very effective and even Cleaning effect of the gas stream from unwanted Particles. Because the cleaning device to separate out particles a guided gas flow, especially for oil separation systems on internal combustion engines, with one Exposed to gas flow, the particles and filter element passing the cleaned gas flow and one assigned to the cleaning device Discharge device for the separated particles, wherein the cleaning device at least one Forced guidance element for the gas flow comprises an at least one change of direction of the gas flow when passing through the cleaning device causes, and the positive control element at the same time forms the filter element, the positive guide element in the direction of the gas flow at least two spaced and offset from each other has arranged baffle elements for the gas flow, the impact elements on at least two, in particular four cylindrical surfaces by one perpendicular to the Direction of entry of the gas flow into the positive guidance element arranged axis are arranged, and the baffle elements on a conical surface support a holding element, the conical surface Part of the discharge device for the deposited particles is such that the Particles over the surface of the
- the gas flow when passing the positive guidance element learns the particles, their density is greater than the density of the gas flow, tangential accelerated to change the direction of the gas flow and can be separated.
- the positive guidance element in the direction of the Gas flow at least two spaced and offset has impact elements arranged to each other the particles to be separated from the gas stream the impact elements on and are caught by these.
- the baffle elements serve at the same time Determination of the change in direction of the gas flow.
- the impact elements on a conical surface a holding element are supported, a cone tip preferably with the central axis the cleaning device coincides. hereby is achieved by the impact elements deposited particles on these, preferably after can slide down and onto the surface of the cone to meet. A lateral Leading the separated particles out of the Cleaning device done. So in particular in a continuous operation a safe one Particles can be separated from the gas flow.
- Invention provided that a feed opening for the Gas flow at an angle of preferably 90 ° to one Outflow opening arranged for the cleaned gas flow is. This will separate out particles effectively supported from the gas stream, in particular when the outflow opening is directed upwards is so that as a result of acting on the particles Gravity separating them from the Gas flow can be supported.
- the cleaning device in the oil separation system is used on internal combustion engines, is particularly advantageous that through that too long operating time almost constant cleaning effect the cleaning device according to the invention Combustion of the internal combustion engine from over one Blowby gas introduced oil fractions almost unaffected can stay.
- the constant Blowby gas parameters can be an existing one Engine management system more precise in terms of good Efficiency and low-emission combustion matched and can also meet the target values very precisely.
- the invention Cleaning device also has the advantage on, the exhaust gas values regarding undesirable Combustion products at a very low level too hold.
- FIG 1 is a cleaning device according to the invention 2 shown in a schematic sectional view, how they're used to separate particles a guided gas stream 8, in particular for oil separation systems in internal combustion engines, use place.
- the cleaning device 2 essentially consists from a positive guide element 4 for the Gas stream 8.
- This essentially comprises a cylindrical one Housing 3, which at its upper flat Front 22 an outflow opening 29 with a cylindrical Has nozzle 30, which leads to a vacuum source, for example one not shown here Intake pipe of an internal combustion engine, leads.
- 3 feed openings over the circumference of the housing 28 is provided, via which the gas flow 8 into the cleaning device 2 can occur.
- the gas stream 8 reaches the jacket surfaces 10 of the cleaning device 2, by a variety of parallel baffle elements 12 arranged to one another are formed become.
- These impact elements 12 are shown in FIG Embodiment essentially as round bars 18 trained and are circular cylindrical Surfaces 16 about a central axis 24 of the housing 3 arranged so that the gas flow 8 is a labyrinth guide must go through before it to the outflow opening 29 or to the nozzle 30 of the cleaning device 2 can reach.
- this labyrinth guide exemplary from four, each from a large number of Round rods 18 formed circular cylindrical surfaces 16.
- the gas flow 8 is deflected by 90 °, since the outflow opening 29 with the nozzle 30 in highest point of the housing 3, centrally in the upper End face 22 is provided. Due to the fixed installation position corresponding to the representation shown in Figure 1a it is ensured that the gas flow 8 of the Blowby gas the cleaning device 2 essentially happened from bottom to top respectively flows through. This can have a cleaning effect most effective way by supporting gravity down on the contained in the intake air Oil components acts, are ensured.
- FIG. 2 shows a variant of a cleaning device 2 with largely the same structure as the embodiment in Figure 1. Same parts as there are provided with the same reference numerals and not again explained.
- FIG. 2a shows the cleaning device 2 in one Sectional view.
- the baffle elements 12 have here Form of circular segments 20, which are also circular cylindrical Areas 16 with increasingly less Distance arranged around the central axis 24 of the housing 3 are.
- the illustrated embodiment are four, each a variety of perpendicular to Gap arranged circle segments 20, Surfaces 16 are provided axially around the central axis 24.
- the surfaces 16 thus each have a multiplicity of Breakthroughs 17 that are offset from one another in this way are arranged so that the gas flow 8 each time it passes a surface 16 is deflected. This will a labyrinth effect analogous to that described in Figure 1 Way achieved.
- the bottom edges of the circle segments 20 are flush with the surface of the cone 32 of the holding element 23 of the housing 3, so that separated oil 36 can flow off to the outside, from where it is in the oil sump of the crankcase can reach.
- Figure 2b shows a schematic plan view of the Cleaning device 2 according to Figure 2a.
- recognizable here are the coaxial in four areas 16 um the central axis 24 of the housing 3 arranged circle segments 20.
- a coaxial extension of the circle segments 20 decreases in the areas 16 after Inside.
- the openings 17 remain in all Areas 16 of equal size.
- the Gas stream 8 always hits a segment of a circle directly 20 of the next surface 16, so that on the as Impact element 12 acting circle segment 20 a good one Separation of the oil particles is possible.
