Specific embodiment
In conjunction with referring to shown in Fig. 1 to Fig. 6, according to an embodiment of the invention, providing a kind of gas-liquid separator, including separator
Shell 1, the shell separator 1 have air inlet pipe 11 and exhaust pipe 12, also have the first filtration members 2, the second filtration members 3, cold
Matchmaker successively enters in the exhaust pipe 12 after first filtration members 2, the separation of the second filtration members 3.In the technical solution, by
In being provided with first filtration members 2, the second filtration members 3 in the shell separator 1, to make to enter via air inlet pipe 11
Gas-liquid two-phase refrigerant can be entered back into after two-stage gas-liquid separation in the exhaust pipe 12, and then enter compressor, pass through
Liquid phase ratio in the refrigerant of two-stage gas-liquid separation will be can be greatly reduced, this is significantly facilitated, and to prevent compressor air suction band liquid existing
The generation of elephant, and then prevent the generation of liquid hit phenomenon.
The setting position of first filtration members 2, the second filtration members 3 in the shell separator 1 can be multiplicity,
For example, first filtration members 2 are arranged for the air inlet of the air inlet pipe 11, so as to carry out the gas of first time to refrigerant
Liquid separation, first filtration members 2 can be using the filter assemblies that gas-liquid separator has in the prior art, it is preferable that described
First filtration members 2 include the central area of discshaped body 21, the discshaped body 21 with protrusion 22, the discshaped body 21
Multiple filter hole 23 are also configured with around the protrusion 22, the protrusion 22 is preferably the semi-round ball towards the air inlet
Body can carry out drainage appropriate to air inlet refrigerant, and the filter hole 23 is then the first time gas-liquid separation to the refrigerant
Direct position.
Preferably, the exhaust pipe 12 has straight pipe 121, bend loss 122 in the shell separator 1, institute
It states welding between straight pipe 121 and bend loss 122 and forms one, second filtration members 3 are arranged around the straight pipe 121,
The internal cavity of the shell separator 1 is divided into the first area 13 being arranged inside and outside, second area 14, second mistake
Filtering has the first filter house 31 on part 3, first filter house 31 penetrates through the first area 13 and second area 14, best
, second filtration members 3 are at tubular structure, the setting concentric with the straight pipe 121 of the second filtration members 3 of tubular, so
The space in the shell separator 1 can be made more rationally compact.
Further, the upper end of second filtration members 3 is connect with first filtration members 2, second filtration members 3
Lower end is connect with the shell separator 1, so that the first area 13 and the second area 14 only pass through first mistake
Filter portion 31 penetrates through, in the technical solution, it is to be understood that second filtration members 3 are empty by the inside of the shell separator 1
Between be divided into the inside and outside two relatively independent regions only linked up by first filter house 31, first area can be made in this way
13 are relatively isolated with the refrigerant gaseous state in second area 14, are conducive to the promotion of gas-liquid separation effect.First filter house 31
Including strainer, the strainer mesh number is 60 mesh~100 mesh, i.e., every 100mm2Area strainer has 60~100 sieve pores, prevents in this way
Mesh number is excessive to cause refrigerant flow resistance to increase, too small to cause gas-liquid separation effect bad.
Further, first filter house 31 is L, the straight tube along the length of 121 length direction of straight pipe
Section 121 straight tube spout diameter be D, D < L≤1.5D, experiment proves that, it is such setting be more advantageous to reduce refrigerant flowing resistance
Power.
The too low liquid phase refrigerant that will lead to of the height of first filter house 31 is by the first area 13 inflow second area
14, it is excessively high, cause stroke of the refrigerant in the shell separator 1 insufficient (this is unfavorable for separation process), it is preferable that described
The height of second filtration members 3 is H, and the lower edge height of first filter house 31 is h, H/4-L/2≤h≤H-L/2.
Certainly, in order to further enhance the gas-liquid separation effect of the gas-liquid separator, it is preferable that the gas-liquid separator
It further include third filtration members 4, the third filtration members 4 are arranged concentrically with second filtration members 3 and around the straight pipe
121.Preferably, the lower edge height of specific second filter house 41 in the third filtration members 4, second filter house 41 is lower than institute
State the lower edge height of the first filter house 31, the upper upper edge for being lower than first filter house 31 along height of second filter house 41
Highly, that is, the filter window of first filter house 31 is integrally higher than the filter window of second filter house 41, in this way
The liquid phase refrigerant in the first area 13 can be effectively prevent to enter when gathering more amount by first filter house 31
Close to the region of the straight pipe 121, prevents separated refrigerant from carrying liquid phase refrigerant again and enter in the exhaust pipe 12.
According to an embodiment of the invention, also providing a kind of compressor, including above-mentioned gas-liquid separator, can further mention
The gas-liquid separation effect of its high refrigerant effectively prevent compressor air suction with liquid and then prevents the generation of liquid hit phenomenon.
Those skilled in the art will readily recognize that above-mentioned each advantageous manner can be free under the premise of not conflicting
Ground combination, superposition.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within principle.Above only
It is the preferred embodiment of the present invention, it is noted that for those skilled in the art, do not departing from this hair
Under the premise of bright technical principle, several improvements and modifications can also be made, these improvements and modifications also should be regarded as guarantor of the invention
Protect range.
