Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 6, the gas-liquid separator of the present embodiment includes:
the shell 1 is approximately cylindrical in outer outline, and can form a cylindrical space with the inside, so that the gas-liquid separation unit 2 can be accommodated, and a working space is provided for the gas-liquid separation unit 2. The housing 1 may include a base 11 and an upper shell 12 capable of forming a sealing area with the base 11, the upper shell 12 and the base 11 together forming a working area of a gas-liquid separator for providing a space for separating gas from liquid. An annular space may be formed between the upper shell 12 and the gas-liquid separation unit 2. Thereby providing space for the downward flow of liquid and the axial movement of gas around the gas-liquid separation unit 2. Of course, in other alternative embodiments, the shape of the housing 1 may be adjusted according to actual needs. The housing may include an inlet that may be used to access a gas-liquid mixture discharged from an automotive engine.
The gas-liquid separation unit 2, the gas-liquid separation unit 2 may be disposed in the casing 1, and the gas-liquid separation unit 2 may include a rotating shaft 24 disposed along a first direction and a plurality of centrifugal discs disposed on the rotating shaft 24, and by rotating the rotating shaft 24 and the centrifugal discs, gas and liquid in a gas-liquid mixture entering from an upper portion of the gas-liquid separation unit 2 are separated from each other, thereby achieving a gas-liquid separation effect. Of course, in other alternative embodiments, other mechanisms capable of achieving the gas-liquid separation effect may be used as the gas-liquid separation unit 2. In this embodiment, the first direction is a longitudinal direction of the paper in fig. 2 and is from top to bottom.
An air outlet pipe 3, one end of the air outlet pipe 3 in the housing 1 may have an air inlet 31 for collecting the separated air, and one end of the air outlet pipe 3 in the housing 1 may be located between the housing 1 and the air-liquid separation unit 2, thereby collecting the air between the housing 1 and the air-liquid separation unit 2. The opening direction of the gas inlet 31 may be directed toward the gas-liquid separation unit 2 so that the gas inlet 31 can collect the gas flowing around the gas-liquid separation unit 2. The gas outlet pipe 3 may be separately provided with respect to the housing 1 and may be moved with respect to the gas-liquid separation unit 2 and the housing 1, so that separate replacement and maintenance may be performed with respect to the gas outlet pipe 3, thereby improving the economy of the gas-liquid separator.
In this embodiment, the gas-liquid mixture enters the gaps between the centrifugal discs from the passages in the center of the centrifugal discs and the gas and liquid are separated by the centrifugal discs rotating at high speed. Wherein, the liquid is thrown to the inner wall of the shell 1 and flows downwards along the inner wall of the shell 1 under the action of gravity; the gas flows inside the casing 1 after being separated in the direction in which the centrifugal disk rotates, and when the centrifugal disk rotates in the clockwise direction as shown in fig. 1, the gas flows in the casing 1 in the clockwise direction. The gas flows around the gas-liquid separation unit 2 and is collected by the gas inlet 31 provided toward the gas-liquid separation unit 2, so that the gas in the casing 1 is discharged through the gas outlet pipe 3.
Borrow by above-mentioned structure, the opening of income gas port 31 is towards gas-liquid separation unit 2 to can make income gas port 31 deviate from the casing 1 inner wall, prevent that the oil mist on the casing 1 inner wall from directly getting into in the income gas port 31, lead to outlet duct 3 can play isolated effect to the liquid that lies in on the casing 1 inner wall, thereby promote vapour and liquid separator's separation effect.
Specifically, as shown in fig. 1 and 2, the gas-liquid separation unit 2 may include a gas-liquid separation module 21 and a blocking module 22, and the blocking module 22 may be disposed adjacent to the gas inlet 31 of the gas outlet pipe 3 with respect to the gas-liquid separation module 21. Thereby making it easier for gas around the barrier module 22 to be collected by the gas inlet 31. The sectional area of the barrier module 22 can be reduced from the gas-liquid separation module 21 to the outlet pipe 3, so that a protective space can be provided for the outlet pipe 3 disposed adjacent to the barrier module 22, and the liquid is prevented from dropping into the gas inlet 31. The blocking module 22 can block the liquid in the gas-liquid separation module 21 from directly entering the gas inlet, so that the liquid in the blocking module 22 and the gas inlet 31 are kept relatively independent. In addition, the barrier module 22 may collect the gas-liquid mixture that is not completely separated in the gas-liquid separation module 21, and separate the gas-liquid mixture therein again by the centrifugal force during the rotation of the barrier module 22.
Specifically, as shown in fig. 2, the baffle plate 23 is sleeved outside the blocking module 22, the baffle plate 23 may extend from one end of the baffle plate adjacent to the gas-liquid separation module 21 to a direction away from the gas-liquid separation module 21, so as to prevent liquid on the baffle plate 23 from flowing onto the blocking module 22, and also enable the baffle plate 23 to be consistent with a direction of gas flowing around the gas-liquid separation module 21, so that gas flow can be kept smooth in a flow passing process.
In this embodiment, the baffle 23 extends along the vertical direction, so that the baffle 23 can guide the liquid in the downward flowing process, and part of the liquid on the gas-liquid separation module 21 can flow downward along the baffle 23 under the action of gravity. Since the baffle 23 extends in a direction away from the gas-liquid separation module 21, the liquid on the baffle 23 can flow downward along the baffle 23 under the action of gravity, and thus the liquid can be prevented from flowing onto the barrier module 22.
Specifically, the projection of the air inlet 31 in the direction extending along the baffle 23 may be located inside the baffle 23. That is, when the baffle 23 extends in the vertical direction, the gas inlet 31 can be covered on the lower end of the baffle 23, and the liquid can be prevented from entering the gas outlet pipe 3 through the gas inlet 31, thereby improving the separation effect of the whole liquid separator.
Specifically, as shown in fig. 2, a first distance is maintained between the gas inlet 31 and the barrier module 22, so that a gas flow space exists between the gas inlet 31 and the barrier module 22, so that gas can be discharged from the inside of the housing 1 through the gas inlet 31. Prevent the air inlet 31 from being unable to intake air due to the close contact between the air inlet 31 and the baffle module 22.
In a preferred embodiment, too large a first distance results in the gas inlet 31 being far from the barrier module 22 and liquid entering the gas outlet 3, and too small a first distance results in the gas inlet 31 being too close to the barrier module 22 and thus preventing the gas inlet 31 from collecting gas. Thus, the first pitch may be between 2-20mm, preferably 6mm as tested repeatedly by the inventors.
Specifically, as shown in fig. 3, the gas-liquid separation module 21 is a centrifugal disk arranged in the axial direction and penetrating the same rotating shaft 24, and an eccentricity exists between the gas inlet 31 and the central axis of the rotating shaft 24. The corresponding area between the gas inlet 31 and the gas-liquid separation unit 2 is increased, so that the gas outlet pipe 3 can obtain a larger opening area and face the flowing direction of the gas flow, and the loss of local gas dynamic pressure is reduced.
In a preferred embodiment, the eccentricity is too small, which results in insufficient extension length of the outlet pipe 3, and the angle between the opening and the incoming gas flow direction is too large to facilitate gas collection, and the eccentricity is too close to the inner wall of the casing 1, which easily brings out oil drops. Thus, the eccentricity may be between 10% and 40% of the centrifugal disc diameter. The eccentricity is preferably 23% after repeated tests by the inventor.
Specifically, as shown in fig. 2, 5 and 6, the shape of the gas inlet 31 is disposed corresponding to the barrier module 22, so that the opening of the gas inlet 31 may correspond to the flow direction of the gas flowing around the gas-liquid separation unit 2, thereby increasing the gas collection amount. Further, the opening area of the air inlet 31 may be made large.
Specifically, as shown in fig. 5 and 6, the outlet pipe 3 may be located at a lower side of the gas-liquid separation unit 2, and the inlet port 31 may have an arc portion 311 extending upward. Since the gas in the casing 1 has both the axial velocity and the tangential velocity along the rotating shaft 24, the design of the upwardly extending arc portion 311 enables the gas inlet 31 to follow the incoming flow direction of the gas flow in both the horizontal direction and the vertical direction, so that the gas pressure loss of the gas inlet 31 can be reduced.
Specifically, as shown in fig. 2, 5 and 6, a sealing ring 4 may be disposed between the outlet pipe 3 and the housing 1, so as to seal the gas-liquid separator and prevent the internal gas or liquid from flowing out. The material of the seal ring 4 may be rubber. Of course, in other alternative embodiments, the material of the sealing ring 4 may be adjusted according to actual needs. The inner side or the outer side of the sealing ring 4 can be provided with an annular positioning block 5, and because the shell 1 internally contains liquid and gas which move along different directions under the working state that the gas-liquid separation unit separates the gas-liquid mixture, the gas outlet pipe 3 is stressed more and unevenly. The positioning block 5 can fix the air outlet pipe 3 in the direction around the axis of the air outlet pipe, so that the stability of the gas-liquid separator is high.
Specifically, the blocking module 22 may be in a circular truncated cone shape, and an opening of the air inlet 31 of the air outlet pipe 3 may be parallel to a side surface of the circular truncated cone shape, so that the opening of the air inlet 31 is in a vertical arc shape with the same distance as the circular truncated cone-shaped blocking module 22, and the air inlet 31 can be ensured to obtain the maximum opening area at the same distance from the blocking module 22.
The principle and the implementation mode of the invention are explained by applying specific embodiments in the invention, and the description of the embodiments is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
