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, with those mentioned in the preamble of claim 1 Characteristics.
- crankcase ventilation balance It is known to overpressure in internal combustion engines in a crankcase through a so-called crankcase ventilation balance. 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.
- the blowby gas is generated by means of the filter element cleaned, being carried in the blowby gas Oil mist is separated through the filter element.
- the separated oil is discharged fed to a collecting area of the internal combustion engine.
- the blowby gas cleaned of the oil becomes the Vacuum source supplied, which is usually from a Intake of the internal combustion engine is formed.
- the cleaning device according to the invention particularly has the advantage of a very effective and even Cleaning effect of the gas flow from unwanted Particles.
- the fact that the cleaning device at least one positive guidance element for comprises the gas stream, the one at least once Change of direction of the gas flow when passing through causes the cleaning device, and the positive guide element at the same time forms the filter element, is advantageously possible effective deposition of particles from gas flows in a simple manner to reach.
- By changing the direction of the gas flow experiences when passing the positive guidance element become the particles whose density is greater than the density of the gas flow tangent to the change in direction accelerates the gas flow and can so be separated.
- two spaced and staggered Has baffle elements meet from the Gas flow particles to be separated on the impact elements and are caught by them.
- the Impact elements also serve to determine the Change of direction of the gas flow.
- the impact elements are preferably arranged so that the Gas flow a multiple change of direction when passing experienced by the cleaning device. So becomes a particularly effective separation of the particles possible from the gas stream. It is particularly advantageous if on any coaxial plane around the axis an equal number of impact elements arranged are, so that with reduced diameter the plane the distance of the baffle elements in one Level decreased. This will make the free passage area for the gas flow in the direction of the longitudinal axis the cleaning device less so that this accelerated with constant volume flow becomes. This enables a particularly good separation reach the particles from the gas stream.
- the baffle elements on a conical surface are supported by a holding element, a cone tip preferably with the central axis the cleaning device coincides.
- a cone tip preferably with the central axis the cleaning device coincides.
- 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 faces upwards is so that as a result of acting on the particles Gravity separating them from the gas stream can be supported.
- the cleaning effect remains with the invention Device almost over the entire operating time constant because the labyrinthine flow paths for the gas flow through the drain and drip option downward a reliable self-cleaning effect exhibit.
- the cleaning device in the oil separation system is used on internal combustion engines, is particularly advantageous that also through the 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. Due to the constant over a long period of operation good separation effect has the invention Cleaning device also has the advantage on, the exhaust gas values with regard to undesired combustion products to keep at a very low level.
- FIG 1 is a cleaning device according to the invention 2 shown in a schematic sectional view, how to separate out particles a guided gas stream 8, in particular for oil separation systems in internal combustion engines, use finds.
- the cleaning device 2 consists essentially 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.
- the so-called blowby gas is through two strongly drawn arrows, which in the drawn representation in a horizontal direction and thus perpendicular to the cylindrical outer contour the cleaning device 2 hit.
- 3 feed openings 28 over the circumference of the housing 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 are formed and are on coaxial planes 16 arranged about a central axis 24 of the housing 3, so that the gas stream 8 pass through a labyrinth guide must before it to the outlet 29 or get to the nozzle 30 of the cleaning device 2 can.
- this labyrinth tour exemplarily from four, each 18 levels formed from a plurality of round bars 16.
- each level Number of equally thick round bars 18 arranged are twisted that a round rod 18 one Gap between two round bars 18 of an adjacent one Level 16 faces.
- the round bars 18 in more than four coaxial planes 16 to group can continue to be thinner than that of the outer layers be carried out and stand closer together, so that the radial flow through the positive guide element increasingly finer oil droplets towards the inside can be filtered out of the gas stream 8.
- the optimal variant with regard to effective cleaning effect and maximum service life can be expediently determine by experiment and is dependent on the number, size and / or type of those to be deposited Particle.
- the gas flow 8 is deflected by 90 °, since the outflow opening 29 with the nozzle 30 in the 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 stream 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.
- the oil fractions are collected and one Oil sump of a crankcase of the internal combustion engine returned.
- they rely Baffle elements 12 on a conical surface 32 of a the lower end face of the housing 3 forming retaining element 23, with one facing upwards Tip 25 of this conical surface 32 on the central axis 24 of the housing 3 is so that on the conical surface 32 running oil 36 to the edges can run down from where one not shown here Return line the oil 36 to the oil sump, for example the crankcase of the internal combustion engine, can supply.
- the round rods 18 can either be flush complete with the conical surface 32 or also passed through suitable holes be like this in the illustrated embodiment the case is.
- Figure 1b shows a schematic plan view of the Cleaning device 2 according to Figure 1a.
- Recognizable here are the multitude of coaxial in four levels 16 arranged around the central axis 24 of the housing 3 Round rods 18, which inwards, that is to the central axis 24 towards, are always closer and so too contribute to a good cleaning effect.
- the cutting plane A-A corresponds to the illustration in Figure 1a.
- Of the Top view can be seen how the round bars 18 on Gap are arranged.
- the round bars 18 every second Level 16 are on a common radial to the central axis 24 arranged.
- the diameter of the planes 16 reduces the distance the round rods 18 in a plane 16. This is what makes one special effective separation of the oil components in the Blowby gas possible.
- 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 coaxial Levels 16 with an increasingly smaller distance around Central axis 24 of the housing 3 are arranged. in the illustrated embodiment are four, each a variety of vertically arranged on gap Circular segments 20, planes 16 axially around the Center axis 24 is provided.
- the levels 16 thus point each have a plurality of openings 17 on the are staggered such that the Gas stream 8 deflected each time it passes through a level 16 becomes. This makes a labyrinth effect analog achieved in the manner described for Figure 1.
- the Bottom edges of the circular segments 20 are flush with the conical lateral surface 32 of the holding element 23 of the Housing 3 from, so that separated oil 36 to the outside can drain from where it is in the oil sump of the crankcase can reach.
- FIG. 2b shows a schematic plan view of the Cleaning device 2 according to Figure 2a.
- Recognizable here are the coaxial in four levels 16 um the central axis 24 of the housing 3 arranged circle segments 20.
- a coaxial extension of the circle segments 20 decreases in levels 16 inwards.
- the openings 17 remain in all levels 16 same size.
- the circle segments 20 in the levels 16 becomes one strong diversion of the gas stream 8 causes.
- the gas flow 8 always meets a circle segment 20 the next level 16, so that as a baffle 12 acting circle segment 20 good separation the oil particle is possible.
- FIG 3 shows a further variant of a cleaning device 2 in a schematic sectional view. Same parts as in the previous figures are provided with the same reference numerals and not explained again.
- this embodiment can of the crankcase ventilation of the Internal combustion engine coming gas stream 8 from below through several openings 28 into the lower end face of the substantially cylindrical housing 26 flow holding element 23 flow.
- the housing 26 however, unlike the previous ones Figures a closed outer surface 27, since the gas stream 8 flows in exclusively from below.
- the housing 26 is through on its top End face 22 with outflow opening located therein 29 and led out connector 30 limited.
- the cleaning effect that is the separation of Oil fractions in the gas stream 8 in this embodiment by a wire mesh 40 respectively a wire screen 41 achieved that the gas stream 8 pass must exit before it exits the orifice 29 and directed to the intake pipe of the internal combustion engine can be.
- the wire mesh 40 respectively Wire screen 41 has a cylindrical contour, and lies on the cone tip 25 of the holding element 23 and thus almost completely fills the inside of the housing 26 out. Between the straight end of the wire mesh 40 or sieve 41 and the after outside sloping conical surface 32 of the holding element 23, however, there is a space. Thereby runs in wire mesh 40 or sieve 41 retained oil 36 either on the inner cylindrical Wall of the housing 26 or over the cone tip 25 of the conical surface 32 downwards.
- Outlet openings 37 are provided. That way the separated oil 36 runs off unhindered, without the incoming gas stream 8 this always sweeps away.
- the one for making the wire mesh 40 or the wire screen 41 used Wire has a smooth surface, so that Oil particles separated from the gas stream 8 are not stick and - as explained - expire.
- a Locking the wire mesh 40 or of the wire screen 41 can for example by snapping of the holding element 23 into the housing 26.
- the structure of the wire mesh 40 used with regard the mesh spacing can be conveniently determine by experiment. Are also possible Combinations of different and preferably after the mesh spacing becomes finer at the top. Advantageous it can still be a wire mesh 40 with to combine differently fine wire screens 41.
