Description
Technical Field
The invention belongs to the mechanical equipment industry, and particularly relates to a gas-liquid separator for separating gas and liquid (solid) media, so as to realize the functions of avoiding liquid impact, gas dust removal, oil-water separation and the like.
Background
The gas-liquid separator is used as an important refrigeration device and is arranged near the air suction port of the compressor and is mainly used for separating gas and liquid (a small amount of impurities) in an outlet medium of the evaporator, so that a refrigerant sucked by the compressor is in a gaseous state, and the phenomenon of liquid impact of the compressor is avoided, and further the compressor is damaged.
The main functional principle of the gas-liquid separator commonly used in the market at present is as follows: after the mixed medium enters the gas-liquid separator, the liquid directly falls into the bottom of the shell due to different specific gravity of the gas and the liquid, the gas escapes into the upper space in the shell, and due to the suction effect of the compressor, the transient pressure difference occurs at the inlet and the outlet of the gas-liquid separator, so that the gaseous refrigerant can be directly pressed into the outlet and enter the compressor, and the liquid refrigerant is accumulated at the bottom of the shell container.
The gas-liquid separators commonly found on the market have the following disadvantages:
1. the gas-liquid separator is impacted on the inner wall of the shell by means of a mixed medium, and the difference of specific gravity of gas and liquid is utilized, so that the separation of gas and liquid is realized; the method can cause larger kinetic energy loss, the larger the speed is, the more obvious the pressure loss is, and the gas-liquid separation efficiency is low; in a refrigeration system, the pressure loss of the low-pressure section can cause the evaporation pressure to be forced to rise, and the heat transfer temperature difference is reduced, so that the heat exchange capacity is reduced, and the evaporation pressure is avoided as much as possible in the design process of the refrigeration system.
2. In the separation process of the gas-liquid separator, a large number of droplets with small particle size are sputtered and then sucked into the gas-liquid separator along with gas, so that a overheat device is additionally arranged between the suction of the compressor and the outlet of the gas-liquid separator, and the equipment cost and complexity are improved.
3. When the gas-liquid separator adopts a standard U-shaped pipeline, the size of the U-shape is larger due to the process reason, so that the volume of the gas-liquid separator is relatively larger, resource waste is caused, the interval between the U-shaped pipeline and the inner wall of the shell is too small, and when a refrigeration system runs at high frequency, the U-shaped pipe frequently collides with the inner wall of the shell, so that noise is increased, and phenomena such as cracking of the welding part of the U-shaped pipe and the like are likely to occur, so that air leakage is caused.

Detailed Description
The gas-liquid separator of the present invention will be described in further detail with reference to the accompanying drawings. It should be understood that the following examples are illustrative of the present invention and are not intended to limit the scope of the present invention.
Example 1
As shown in fig. 1 to 3, the gas-liquid separator of the present invention comprises a housing 2 having an upper cover 1 and a U-shaped tube 3 provided in the housing 2, wherein an outlet 11 communicating with an exhaust port 32 of the U-shaped tube 3 is provided at the top of the upper cover 1, and a medium inlet 12 is provided at the side surface thereof, wherein:
a cylinder 4 is provided inside the upper cover 1, a medium passage 40 is formed between the outer wall of the cylinder 4 and the inner wall of the upper cover 1, and the center line of the medium inlet 12 is offset from the center line of the cylinder 4.
The U-shaped tube 3 is a non-standard U-shaped tube, the bending degree of the crown portion 30 is large, and specifically, the included angle α between the center lines of the two straight tubes of the U-shaped tube 3 is preferably >0 ° and <90 °.
The angle β between the centre line of the medium inlet 12 of the upper cover 1 and the centre line of the cylinder 4 is preferably >0 ° and <90 °.
In this embodiment, the air inlet 31 of the U-shaped tube 3 is located in the cylinder 4, and preferably, the air inlet 31 is trumpet-shaped.
Preferably, the crown portion 30 of the U-shaped tube 3 is further provided with an oil return hole 33, and a portion of the U-shaped tube 3 near the air outlet end face is further provided with an overflow hole 34.
In addition, screw holes 13 (fig. 4) are provided on the upper cover 1 for connection with other pipelines.
Since the inlet medium of the upper cover 1 will first make a rotational movement around the outer wall of the cylinder 4 and then make a rotational movement along the inner wall of the housing 2, the diameter R of the housing 2 2 Outer diameter R of cylinder 4 3 Diameter phiD of the media inlet 12 1 And the distance between the centre line of the medium inlet 12 and the centre level of the cylinder 4L 1 Preferably, the following are satisfied:
(R 2 -R 3 )≥ΦD 1 2, and R 3 ≤(L 1 +ΦD 1 /2)≤R 2 ，
Through experimental detection, the pressure loss of fluid passing through the inlet and outlet of the gas-liquid separator can be reduced to a greater extent by meeting the above relation, and higher gas-liquid separation efficiency can be brought.
To reduce the pressure resistance and improve the separation efficiency, the diameter phi D of the U-shaped tube 3 2 Diameter R of housing 2 2 The method meets the following conditions:
in order to ensure that inlet medium and large droplets do not directly enter the trumpet shaped medium inlet 12, the distance L between the centre line of the medium inlet 12 of the upper cover 1 and the end surface of the cylinder 4 2 ≥ΦD 1 2, the distance L between the end face of the trumpet-shaped air inlet 31 of the U-shaped pipe 3 and the end face of the cylinder 4 3 ≥ΦD 2 /2。
The diameter of the oil return hole 33 on the U-shaped pipe 3 is 1-2 mm, and the height phi D of the central line of the oil return hole 33 from the bottom of the shell 2 2 Distance L from the center line of the medium inlet 12 of the upper cover 1 to the end face of the cylinder 4 2 The method meets the following conditions:
ΦD 2 ＜L 2 ≤20mm。
according to the design, the phenomenon that the storage flow in the gas-liquid separator is too small under the maximum flow can be avoided, and lubricating oil cannot return to the compressor along with the refrigerant.
In this embodiment, as shown in fig. 5, a filter screen 5 may be further installed in the casing 2 to improve the gas-liquid separation efficiency, and at the same time, impurities may be filtered to avoid blocking the oil return hole. Preferably, a drying agent (not shown) may be further added to the underside of the filter screen 5 to absorb moisture therein.
As shown in fig. 3 and 4, the mixed medium flows from the medium inlet 12 into the medium passage 40 of the upper cover 1, is sprayed on the outer wall of the cylinder 4, and is rotated around the outer wall; due to the self-weight and viscous force of the fluid, a waterfall surface is formed on the outer wall, the area of the liquid leaking in the gas-liquid separator is increased, so that the gas is better separated, then the gas is impacted to the inner wall of the shell in a parabolic shape, the fluid bounces, one part of the fluid is sputtered into the shell 2, and the other part of the fluid is attached to the inner wall of the shell 2 due to the viscous force and the self-weight and falls to the bottom of the shell 2 along the wall surface; during the impact, the liquid is broken up, further allowing the gas to escape from the liquid, and the sputtered small particle liquid absorbs the heat of the superheated gas to become gaseous.
When the flow speed is higher, the fluid rotating path around the outer wall of the cylinder 4 is longer, the area of the fluid surface of the waterfall is further enlarged, the angle of the fluid surface impacting the inner wall of the shell 2 is more approximate to 0 degrees, namely the fluid surface of the fluid is closer to the tangential direction of the inner wall and impacts the inner wall surface, the separation effect is enhanced along with the secondary rotation separation of the inner wall surface of the shell 2, compared with the effect of impacting the inner wall surface with the inner wall surface of 90 degrees, the pressure loss is reduced, because the fluid only loses a little kinetic energy along with the rotation of the wall surface, under the action of centrifugal force, after the gas is separated, the fluid enters the U-shaped pipe 3 under the action of pressure difference, and the 90-degree angle impacts the inner wall surface, in essence, the fluid is scattered to the greatest extent as possible, the area of the fluid exposed in the gas-liquid separator is increased, the gas can be better separated out, the kinetic energy of a great part is lost, and meanwhile, the impact noise with larger decibel is accompanied.
Due to the action of dead weight and viscosity force, a liquid medium (comprising lubricating oil and impurities) can fall down to the bottom of the shell 2 along the inner wall surface of the shell 2 or directly, the crown part 30 of the U-shaped pipe 3 is greatly bent, and is immersed into the liquid medium in a large area, on one hand, the gaseous refrigerant in the aluminum pipe exchanges heat with the liquid refrigerant to gasify part of the liquid refrigerant, on the other hand, due to the siphoning action, the lubricating oil can be sucked into the compressor along with the refrigerant, and under the condition of stable system, the height of the sucked refrigerant containing the lubricating oil in the U-shaped pipe 3 is a dynamic balance process, namely, the sucked liquid refrigerant and the quantity discharged from an outlet are kept to be constant; when the system suddenly changes and the amount of the sucked liquid refrigerant greatly increases, the refrigerant exceeding the overflow hole 34 flows out, and after the system is stabilized, the sucked refrigerant reaches new dynamic balance again, so that the phenomenon of liquid impact caused by that a large amount of liquid refrigerant directly rushes into the compression cavity of the compressor is avoided, and the phenomenon of liquid impact caused by the sudden change of flow can be relieved or even eliminated to a certain extent due to the existence of the overflow hole 34.
In order to facilitate normal oil return of the compressor, the height of the compressor is lower than that of the evaporator, and the heights of the gas-liquid separator and the air inlet of the compressor are basically the same, and the distance is relatively short, so that the outlet of the evaporator can be connected with the inlet of the gas-liquid separator in an inclined straight line, on one hand, the pressure loss of a pipeline section is reduced, on the other hand, lubricating oil in the evaporator is facilitated to return to the compressor along with a refrigerant from the pipeline, and the lubricating oil cannot be gathered at an elbow, and the inlet is arranged at the side edge and the outlet is arranged at the top, so that the lubricating oil is particularly suitable for being used in a heat pump system for a compact vehicle.
Example 2
As shown in fig. 5, in this embodiment, a filling port 6 is further provided in the upper cover 1 of the gas-liquid separator, as compared with embodiment 1.
The filling opening 6 is additionally arranged on the upper cover 1 of the gas-liquid separator, which is favorable for filling the system, the filling opening of the traditional refrigerating system is positioned between the air inlet of the compressor and the outlet of the evaporator, and after a large amount of two-phase refrigerant is filled, the compressor is easily damaged due to the fact that a large amount of liquid refrigerant is accumulated in the compressor when the compressor is started for the first time.
In this embodiment, the filling port 6 is disposed on the housing 2 of the gas-liquid separator, so that the liquid refrigerant is buffered inside the housing 2, and the sucked refrigerant is still a gaseous refrigerant when the compressor is started. The filter screen is additionally arranged in the shell 2, so that bubbles are generated by flowing liquid refrigerants, gas is better separated, a filtering effect is achieved, impurities in a refrigerating system are separated, oil return holes are prevented from being blocked, oil return is abnormal, and the compressor is burnt out.
While the gas-liquid separator of the present invention has been described in detail with reference to specific embodiments thereof, it will be understood that equivalents are possible in light of the disclosure of the invention and are intended to fall within the scope of the invention.
