Definitions
- the invention relates to a device for the separation of liquids from gases, in particular for the separation of oil particles from blow-by gases of the crankcase ventilation of internal combustion engines.
- crankcase ventilation gases e.g. Cyclone separators of different types, known as single or multi cyclones.
- the accumulated in the crankcase, loaded with oil droplets gas is introduced tangentially into the cyclone. Due to the centrifugal forces acting in the cyclone, the oil contained in the gas stream is deposited on the inner wall of the cyclone and fed via a arranged in the lower part of the cyclone outlet the crankcase or oil sump of the engine.
- the gas flow is deflected in the cyclone, flows through a arranged at the top of the cyclone dip tube as clean gas and enters the intake tract of the engine.
- a single cyclone separator has only a limited working range, which leads to insufficient separation in the case of excessively low volume flows and to high pressure loss in the case of excessively high volume flows.
- the working area of multicyclones connected in parallel can also be extended by connecting and shutting off individual cyclones by means of a valve.
- Such multicyclones are e.g. designed as an independent module and claim a relatively large amount of space, since a spatial separation of the components raw gas, separated oil and clean gas is required.
- oil separators are integrated in the cylinder head cover of the internal combustion engine, as disclosed, for example, in DE 10 2004 019 154 A1.
- the integration of cyclone separators in a cylinder head cover inevitably increases their complexity and requires a relatively large installation space.
- Rotary tube separators which are predominantly flowed axially, are also known.
- the rotational movement is generated by vanes, which are arranged at the gas inlet.
- DE 10 2004 037 157 A1 discloses such a liquid separation device for separating liquid or liquid mist from a gas, in which, instead of guide vanes, helical guide segments which extend over virtually the entire length of the tubes are provided.
- This multi-tube separator consists of at least one plate-shaped base support on which at least one diesstechniksab- separating element is arranged.
- This consists of a flow tube with a gas inlet and a gas outlet. Between these, a helical segment is arranged in the flow tube whose helical surfaces form a helical flow path with the inner wall of the tube.
- the helical segment has a length of less than half a turn.
- a plurality of base support can be arranged with a plurality of separation elements, wherein the direction of rotation in a flow path can run the same or in opposite directions.
- the separation device can be arranged in a cavity of the cylinder head cover behind a labyrinth-like coarse separator.
- the blow-by gas entering axially into the flow tubes is set in rotating motion by the helical segments, whereby the oil is expelled from the gas, deposited on the inner wall of the flow tubes, transported to the outlet of the flow tubes by the gas flow and into a siphon expires. Due to the arranged in the tube separators or flow tubes helical segments, a rotational flow is generated in the
- the invention has for its object to provide a device for the separation of liquids from gases, in particular for the separation of oil particles from blow-by gases of the crankcase ventilation of internal combustion engines, which is characterized by a simple, inexpensive and space-saving design and with the a good separation efficiency can be achieved.
- the flow tubes arranged in the plate-shaped basic carrier have at least one tangentially arranged gas inlet opening at their end pointing in the gas inlet direction. At the adjacent to this end face the flow tubes are closed. Since each flow tube forms a separating element or a tube separator, there is a parallel connection. Since the gas stream dividing onto the individual flow tubes is introduced into the latter only tangentially, a flow pattern is produced which leads to an improvement in the separation efficiency in comparison with the known, axially flowed tube separators.
- the tangential flow creates a combined rotational and axial flow with a swirl component in the flow tubes, with the rotational flow in the flow tubes rotating several times through 360 °. The number of rotations is
- the gas flow reaches higher rotational frequencies and larger centrifugal forces arise. This leads to a significantly improved separation efficiency.
- the deposited on the inner wall of the flow tubes liquid particles are entrained in the flow direction and drip due to gravity at the gas outlet opening of the flow tubes, collect at the bottom of the installation space and are discharged from this via a discharge opening.
- the device can be designed as a very small effective unit that requires only a small installation space.
- the tangential gas inlet openings of the passage tubes may be slit-shaped or slit-shaped.
- the individual flow tubes may also have a plurality of gas inlet openings, which are preferably arranged radially offset from one another.
- the gas inlet openings may also have different sized cross-sectional areas.
- the individual flow tubes preferably have an inner diameter of 2 to 20 mm and a length which is at least 2 times the inner diameter of the flow tubes.
- more than 100 flow tubes preferably 30 to 50, can be arranged in a base support.
- the flow tubes can project beyond the plate-shaped base support in one direction, thus terminate flush with the frame of the base support, or project beyond the base support on both sides.
- the base support can also be designed as a wall section of a housing or installation space.
- the outer shape of the base support may be various, e.g. rectangular, circular or oval, and adapted to the respective installation conditions.
- the flow tubes should be flush with each other at the gas inlet side.
- the frontal openings on the gas inlet side can be closed by means of a cover plate.
- the individual flow tubes can already be made in the production so that they have no frontal opening on the gas inlet side.
- the spring valves each have a sealing surface, which close at least one or more flow tubes on the gas outlet side.
- the spring valves close the gas outlet side under the action of a bias.
- the bias voltage can be used to set the differential pressure at which the valve opens.
- the use of several spring valves with different bias voltages also allows a staggered connection of further tube separators, whereby the control of the separator can be adapted even more precisely to the respective operating conditions.
- the plate-shaped base support can be equipped with flow tubes, except for a peripheral edge section.
- the acting in the basic principle as a parallel circuit separator can also be extended as a combined series circuit by a plurality of plate-shaped base support with flow tubes spaced from each other are arranged.
- the distance between the individual base supports must be at least so large that the drops emerging from the flow tubes can fall in the direction of gravity and are not entrained by the gas flow into the gas inlet openings of the flow tubes of the following base support.
- the distance between the base supports is 10 to 20 mm.
- a base support which is to be used for the deposition of larger particles or drops (coarse separator) is advantageously equipped with flow tubes, which have an enlarged tangential inlet cross-section and a larger inner diameter.
- Coarse separators have a higher absorption capacity for larger particles, but do not divorce the smaller particles due to the lower centrifugal forces. These are then deposited in the downstream basic carrier for fine separation, whose flow tubes have smaller diameters and smaller inlet cross-sections. Pre-separation can prevent overcharging of the fine separator.
- each base support or separator is assigned a separate liquid flow.
- the flow tubes can be designed inclined in the direction of the liquid collecting point. As a result, a better drainage of the separated liquid particles is achieved.
- the plate-shaped base support in the installation space can also be arranged in an inclined position. As a result, the flow tubes assume an obliquely downward position, so that the liquid deposited in the flow tubes can drain well in the direction of the liquid collection point.
- a single or a plurality of plate-shaped base support are arranged in a housing or installation space.
- the housing or the installation space have a raw gas inlet, a clean gas outlet and a liquid outlet and thus forms a separation unit.
- a space provided in the cylinder head cover space is used as an installation space in a separation of oil from blow-by gases of internal combustion engines.
- Cylinder head covers are preferably as
- the proposed separation device is particularly well suited for this purpose, both as a fine separator or as a combined coarse and fine separator due to their space-saving design and their low weight.
- the plate-shaped base support with the flow tubes are also made of plastic and can injection molding in a molding process in combination with a component of the cylinder head cover are designed as a one-piece, integral component.
- connection for supplying the blow-by gas, the clean gas outlet and the oil outlet are in this case also an integral part of the cylinder head cover.
- a plurality of separation units can also form a functional unit, wherein the individual separation units are connected in parallel.
- Under a separation unit is a housing or installation space with gas inlet, at least one base support with flow tubes, clean gas outlet and liquid outlet to understand.
- the respective gas inlets of the individual separation units can be connected separately via corresponding valves, which are integrated into the distribution lines for the supplied gas volume flow.
