Description

Technical Field

[0001] The utility model relates to the technical field of compressors, and in particular to a gas-liquid separator and compressor equipment. Background Art

[0002] The liquid separator, also known as the gas-liquid separator, separates the gas-liquid mixture from the evaporator. The separated gas enters the compressor through the separator's outlet, while the separated liquid refrigerant accumulates at the bottom of the separator. The separator's primary function is to prevent liquid refrigerant from directly entering the compressor, thereby preventing liquid hammer.

[0003] When the dryness at the separator inlet is high, the existing separator is sufficient to separate the gas and liquid.

[0048] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0050] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0051] The utility model provides a gas-liquid separator 100, please refer to Figures 1 to 12 The gas-liquid separator 100 includes a separation chamber 10, a first filter assembly 201, a second filter assembly 202, a first connector 30, and a second connector 40. The first filter assembly 201 and the second filter assembly 202 are vertically spaced apart within the separation chamber 10, thereby dividing the separation chamber 10 into a first cavity 11, a second cavity 12, and a third cavity 13, which are arranged vertically from top to bottom. The first cavity 11 is used to pass a gas-liquid mixture or a gaseous medium.

[0052] The first connecting member 30 has a first channel 31; the first end of the first channel 31 is connected to the first cavity 11, and the second end of the first channel 31 is connected to the third cavity 13; the second connecting member 40 has a second channel 41; the first end of the second channel 41 is connected to the second cavity 12, and the second end of the second channel 41 is used to communicate with the suction cavity of the compressor 200; the gas, or gas-liquid mixture, or gaseous medium in the second cavity 12 enters the second channel 41 through the first port of the second channel 41, and then enters the suction cavity of the compressor 200 through the second port of the second channel 41.

[0053] When a gas-liquid mixture is introduced into the first cavity 11, it can be divided into two paths: the first path of the gas-liquid mixture passes through the first filter assembly 201 and enters the second cavity 12. During this process, the separated liquid flows through the second filter assembly 202 under the action of gravity to the bottom of the third cavity 13; the second path of the gas-liquid mixture enters the third cavity 13 through the first channel 31. During this process, the separated liquid remains at the bottom of the third cavity 13 under the action of gravity, and the separated gas flows upward to pass through the second filter assembly 202 and enter the second cavity 12. In the above two flows of the gas-liquid mixture, due to changes in the flow velocity, droplet size, and distribution of the gas-liquid mixture flow field, the followability of the droplets is weakened, and the liquid and gas in the gas-liquid mixture are separated. Due to the arrangement of the first filter assembly 201 and the second filter assembly 202, the gas or gas-liquid mixture entering the second cavity 12 must be filtered by the first filter assembly 201 or the second filter assembly 202, thereby ensuring that the gas or gas-liquid mixture entering the second channel 41 and the compressor 200 must be filtered, thereby avoiding the occurrence of liquid hammer problems.

[0054] When a gas-liquid mixture is introduced into the first cavity 11, liquid will be separated from the gas-liquid mixture during the process from the entrance into the first cavity 11 to the first filter assembly 201. The separated liquid needs to pass through the first filter assembly 201 under the action of gravity. When a large amount of separated liquid is present, it will accumulate on the first filter assembly 201. If the filter mesh of the first filter assembly 201 is dense, a large amount of liquid will accumulate on the first filter assembly 201. By providing the first connecting member 30, when the liquid level of the liquid accumulated on the first filter assembly 201 reaches the first end of the first channel 31, a portion of the liquid accumulated on the first filter assembly 201 can flow directly into the third cavity 13 through the first channel 31, thereby avoiding excessive liquid accumulation on the first filter assembly 201, thereby avoiding affecting the gas-liquid separation effect of the gas-liquid separator due to excessive liquid accumulation on the first filter assembly 201.

[0055] When a gaseous medium is introduced into the first cavity 11, it will be divided into two paths; the first path of gaseous medium passes through the first filter component 201 and enters the second cavity 12; the second path of gaseous medium passes through the first channel 31 and enters the third cavity 13, and then passes through the second filter component 202 and enters the second cavity 12; therefore, the gaseous medium entering the second cavity 12 must be filtered by the first filter component 201 or the second filter component 202, thereby ensuring that the gaseous medium entering the second channel 41 and the compressor 200 must be filtered.

[0056] The gas-liquid separator 100 has an inlet communicating with the first cavity 11 , so that a gas-liquid mixture or a gaseous medium is introduced into the first cavity 11 through the inlet.

[0057] In addition, since the gas, or gas-liquid mixture, or gaseous medium entering the second cavity 12 must have been filtered by the first filter component 201 or the second filter component 202, impurities in the gas, or gas-liquid mixture, or gaseous medium can be filtered out, preventing the gas, or gas-liquid mixture, or gaseous medium from carrying impurities into the second channel 41 and the compressor 200; impurities entering the compressor 200 will cause abnormal wear of the compressor and even cause compressor failure.

[0058] It should be noted that the first end of the second channel 41 of the present application is connected to the second cavity 12, that is, the first end of the second channel 41 is connected to a place with a low content of liquid or liquid medium. This can prevent more liquid medium from entering the compressor, thereby avoiding liquid hammer caused by wet compression of the compressor.

[0059] Optionally, the gas-liquid mixture and medium mentioned in this application are both refrigerants.

[0110] By arranging the filter portion 221 relative to the through-hole group on the bracket 21 and arranging the guide holes relative to the filter portion 221, the filter portions 221 of all filter elements 22 can cover all through-hole groups and all guide holes to ensure the filtering effect and prevent impurities from entering the second channel 41 and the compressor 200.

[0111] In this embodiment, at least a portion of the filter portion 221 of the filter element 22 of the first filter assembly 201 protrudes toward the first cavity 11; the filter element 22 of the first filter assembly 201 is located on the side of the bracket 21 facing the first cavity 11. At least a portion of the filter portion 221 of the filter element 22 of the second filter assembly 202 protrudes toward the third cavity 13; the filter element 22 of the second filter assembly 202 is located on the side of the bracket 21 facing the third cavity 13.

[0112] The utility model also provides a compressor device, such as Figures 1 to 12 As shown, it includes a compressor 200 and the above-mentioned gas-liquid separator 100.

[0113] Specifically, the compressor 200 includes a terminal cover 210 , a rubber stopper 220 , an upper cover assembly 230 , a pump body assembly 240 , and a lower cover 250 ; a refrigeration oil pool 260 is provided at the bottom of the compressor 200 .

[0114] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0115] The gas-liquid separator 100 provided by the present invention includes a separation chamber 10, a first filter assembly 201, a second filter assembly 202, a first connector 30, and a second connector 40. The first filter assembly 201 and the second filter assembly 202 are vertically spaced apart within the separation chamber 10, thereby dividing the separation chamber 10 into a first cavity 11, a second cavity 12, and a third cavity 13, which are arranged vertically from top to bottom. The first cavity 11 is used to pass a gas-liquid mixture or a gaseous medium.

[0116] The first connecting member 30 has a first channel 31; the first end of the first channel 31 is connected to the first cavity 11, and the second end of the first channel 31 is connected to the third cavity 13; the second connecting member 40 has a second channel 41; the first end of the second channel 41 is connected to the second cavity 12, and the second end of the second channel 41 is used to communicate with the suction cavity of the compressor 200; the gas, or gas-liquid mixture, or gaseous medium in the second cavity 12 enters the second channel 41 through the first port of the second channel 41, and then enters the suction cavity of the compressor 200 through the second port of the second channel 41.

[0117] By setting the first connecting member 30, when the liquid level of the liquid accumulated on the first filter component 201 reaches the first end of the first channel 31, a part of the liquid accumulated on the first filter component 201 can flow into the third cavity 13 through the first channel 31 to avoid excessive liquid accumulation on the first filter component 201, thereby solving the problem of a large amount of liquid refrigerant easily accumulating on the filter component in the gas-liquid separator of the prior art.

[0118] If too much liquid accumulates on the first filter assembly 201, it is very likely that too much liquid will pass through the first filter assembly 201 at one time, which will lead to insufficient liquid separation, causing liquid to directly enter the second channel 41, and then cause the compressor to inhale liquid medium, resulting in wet compression, which will affect the reliability of the compressor. By providing the first connector 30, it is possible to prevent excessive liquid from accumulating on the first filter assembly 201, so that too much liquid will not pass through the through-hole group of the bracket 21 of the first filter assembly 201 at one time, thereby achieving more sufficient liquid separation, better liquid separation effect, better gas-liquid separation effect, reducing the risk of liquid being inhaled by the compressor, and thus ensuring the reliability of the compressor.

[0119] If too much liquid accumulates on the first filter assembly 201, it will also cause greater resistance in the section from the inlet pipe 60 to the first end of the fourth connecting pipe 42, resulting in a significant pressure loss within the gas-liquid separator. This will cause the pressure at the compressor suction inlet to be low, and in turn, the compressor suction specific volume to be low, which will affect the compressor's energy efficiency. By providing the first connecting member 30, it is possible to avoid excessive pressure loss within the gas-liquid separator.
