[0022] Figure 1A shows a perspective view of a gas-liquid separator 100 according to a first embodiment of this application. Figure 1B shows a vertical sectional view of the gas-liquid separator 100 shown in Figure 1A. Figure 1C shows a transverse sectional view of the gas-liquid separator 100 shown in Figure 1A. Figure 1D shows an axial sectional view of the gas-liquid separator 100 shown in Figure 1A. As shown in Figures 1A-1D, the gas-liquid separator 100 includes a housing 101. The housing 101 includes a cylindrical housing sidewall 111 and a first end plate 112 and a second end plate 113 located at opposite ends of the housing sidewall 111. The cylindrical housing sidewall 111 has a transverse axis X. The first end plate 112, the second end plate 113, and the housing 101 define a housing cavity 121. The housing 101 also includes a housing inlet 102 and a housing upper outlet 103. The housing inlet 102 is disposed on the first end plate 112. The housing upper outlet 103 is disposed on the upper part of the housing sidewall 111. The gas-liquid separator 100 also includes an inlet pipe 141 and an outlet pipe 142. The inlet pipe 141 is connected to the housing inlet 102 and is used to introduce the gas-liquid mixture into the gas-liquid separator 100. The outlet pipe 142 is connected to the housing outlet 103 and is used to lead the separated gas out of the gas-liquid separator 100.

[0023] The gas-liquid separator 100 also includes a liquid storage device 104. The liquid storage device 104 is located below the side wall 111 of the housing and near the second end plate 113. The liquid storage device 104 includes a liquid storage cavity 151 and a liquid storage outlet 152. The liquid storage cavity 151 communicates with the housing cavity 121. The liquid storage outlet 152 is located at the lower part of the liquid storage device 104 and is used to lead the separated liquid out of the gas-liquid separator 100.

[0024] The gas-liquid separator 100 also includes a separator cylinder assembly 120 disposed in the housing cavity 121. The separator cylinder assembly 120 is disposed near the first end plate 112 such that it is a certain distance away from the liquid storage device 104. The separator cylinder assembly 120 includes an outer cylinder 122 and an inner cylinder 124. The outer cylinder 122 and the inner cylinder 124 have the same axis Y. The axis Y is arranged in the vertical direction. In other words, the axis Y of the separator cylinder assembly 120 is transverse to the axis X of the housing sidewall 111. The outer cylinder 122 is supported on the bottom of the housing sidewall 111. The inner cylinder 124 is disposed in the outer cylinder 122, and the upper edge of the inner cylinder 124 is flush with the upper edge of the outer cylinder 122. The lower edge of the inner cylinder 124 is located in the middle of the outer cylinder 122, thereby allowing the outer cylinder 122 to define a lower space 128 located at the lower part of the separator cylinder assembly 120. There is a certain distance between the outer cylinder 122 and the inner cylinder 124 to form an annular separation space 126 located on the upper part of the separation cylinder assembly 120.

[0025] The separator assembly 120 also includes a top plate 172 and an anti-vortex plate 171. The top plate 172 is annular and covers the upper edges of the outer cylinder 122 and the inner cylinder 124, thereby sealing the top of the separation space 126 and preventing it from communicating with the housing cavity 121 through the top. Simultaneously, since the top plate 172 does not cover the hollow portion of the inner cylinder 124, the hollow portion of the inner cylinder 124 forms an upper outlet 129. The lower space 128 located at the bottom of the separator assembly 120 can communicate with the housing cavity 121 through the upper outlet 129. The anti-vortex plate 171 is horizontally positioned in the lower space 128, and its front and rear portions are connected to the outer cylinder 122 to form channels 173 with the outer cylinder 122 on both the left and right sides.

[0026] The separator assembly 120 also includes an upper inlet 127 and a lower outlet 130. The upper inlet 127 is located at the upper part of the outer cylinder 122 and is positioned close to the outer cylinder 122 so that when the gas-liquid mixture flows into the annular separation space 126 at the upper part of the separator assembly 120, it can be close to the outer cylinder 122. In the embodiments of this application, the inlet pipe 141 extends from the outside of the gas-liquid separator 100 into the gas-liquid separator 100 and communicates with the housing inlet 102 and the upper inlet 127 of the separator assembly 120, thereby allowing the gas-liquid mixture to directly enter the separation space 126 of the separator assembly 120. The lower outlet 130 is located at the lower edge of the outer cylinder 122 and is located on the side opposite to the liquid storage device 104, so that the lower space 128 communicates with the housing cavity 121 through the lower outlet 130. In this application, the lower outlet 130 is located on the side of the outer cylinder 122 away from the liquid storage device 104, so that the lower outlet 130 can be as far away from the liquid storage device 104 as possible.

[0027] The gas-liquid separator 100 also includes a baffle plate 131. The baffle plate 131 is located approximately in the middle of the housing cavity 121. In other words, in the direction of the axis X of the cylindrical housing sidewall 111, the baffle plate 131 is located between the upper outlet 129 of the separator cylinder assembly 120 and the upper outlet 103 of the housing. The baffle plate 131 approximately divides the housing cavity 121 into a left and a right portion. The baffle plate 131 extends downward from the top of the housing sidewall 111 beyond the upper outlet 129 of the separator cylinder assembly 120, and the lower end of the baffle plate 131 is at a certain distance from the bottom of the housing cavity 121, thereby forming a baffle plate communication port 176, allowing the gas-liquid mixture to flow from the left portion of the housing cavity 121 to the right portion of the housing cavity 121.

[0028] The gas-liquid separator 100 also includes a baffle box 132. The baffle box 132 includes a front plate and a rear plate, a left plate and a right plate, all positioned opposite each other, and a bottom plate located below the front, rear, left, and right plates. The front, left, rear, and right plates are connected sequentially and to the bottom plate, thus forming a baffle box 132 with an upper opening. The upper part of the baffle box 132 surrounds the upper outlet 103 of the housing and is connected to the side wall 111 of the housing. The front and rear plates of the baffle box 132 have several connecting holes 133, allowing the housing cavity 121 to communicate with the upper outlet 103 of the housing through these holes. The bottom plate of the baffle box 132 has a hole 175. When the liquid in the gas-liquid mixture is separated in the baffle box 132, it accumulates at the bottom of the baffle box 132. Through the hole 175, the liquid can drain from the baffle box 132 and fall to the bottom of the housing cavity 121.

[0029] The following describes in detail the trajectory of the gas-liquid mixture after it enters the gas-liquid separator 100 and its separation process:

[0030] Referring to Figure 1D, a gas-liquid mixture with a certain velocity can enter the gas-liquid separator 100 through the inlet pipe 141 and the upper inlet 127 of the separator assembly 120. Entering the annular separation space 126, the gas-liquid mixture moves along the annular path. During this movement, the gas-liquid mixture collides with the outer cylinder 122 and the inner cylinder 124. Because liquids have a greater centrifugal force than gases, after colliding with the outer cylinder 122 and the inner cylinder 124, a portion of the liquid in the gas-liquid mixture (e.g., a larger mass liquid) flows downwards along the outer cylinder 122 and the inner cylinder 124 due to gravity, passing through the channel 173 and falling to the bottom of the separator assembly 120. The liquid falling to the bottom of the separator assembly 120 can flow out of the separator assembly 120 from the lower outlet 130 and into the bottom of the housing cavity 121, and finally into the liquid storage device 104. On the other hand, after the gas-liquid mixture impacts the outer cylinder 122 and the inner cylinder 124, the gas-liquid mixture separated from a portion of the liquid flows downward to the lower space 128 of the separator assembly 120. Since the lower space 128 is equipped with an anti-vortex plate 171, the downward-flowing gas-liquid mixture does not impact the liquid in the lower space 128, thus preventing the gas-liquid mixture from carrying away the separated liquid. The gas-liquid mixture flowing into the lower space 128 changes its direction of movement and flows upward to exit the separator assembly 120 from the upper outlet 129. The direction of movement of the gas-liquid mixture exiting the separator assembly 120 changes again, flowing downward through the baffle plate connection port 176 into the right side of the housing cavity 121. The direction of movement of the gas-liquid mixture entering the right side of the housing cavity 121 continues to change upward, flowing into the baffle box 132 through several connecting holes 133 on the front and rear plates of the baffle box 132, and finally exiting the gas-liquid separator 100 from the upper outlet 103 of the housing.

[0031] The gas-liquid separator 100 of this application has at least the following advantages: First, the gas-liquid separator 100 of this application can achieve high separation efficiency. Specifically, the gas-liquid separator 100 of this application can perform two separations with a high separation rate for the liquid in the gas-liquid mixture. The first separation occurs in the separation cylinder assembly 120. The liquid in the gas-liquid mixture flowing through the annular separation space 126 is separated due to centrifugal force. The second separation occurs after the gas-liquid mixture flows out of the annular separation space 126, where it undergoes multiple changes in direction of movement within the housing cavity 121. Specifically, the flow space defined by the separation space 126 is relatively small, while the space of the housing cavity 121 after flowing out of the annular separation space 126 is relatively large. The gas-liquid mixture flowing out of the annular separation space 126 enters the larger space from the smaller space, and its flow rate slows down. For the gas-liquid mixture with a slower flow rate, due to the difference in mass between the gas and liquid, the liquid is more easily separated from the gas when the direction of movement of the gas-liquid mixture changes. Therefore, after the gas-liquid mixture flows out of the annular separation space 126, each change in the direction of movement will separate a portion of the liquid from the gas-liquid mixture, which will fall to the bottom of the shell cavity 121 due to gravity. Second, the liquid in the gas-liquid separator 100 of this application can form a liquid seal, thereby preventing gas in the housing cavity 121 from flowing out of the gas-liquid separator 100 through the liquid storage outlet 152. Specifically, the gas-liquid separator 100 of this application is provided with a liquid storage device 104. The liquid storage cavity 151 has a large volume, which can store a certain amount of liquid and maintain the liquid at a certain height, thereby forming a liquid seal at the liquid storage outlet 152 of the gas-liquid separator 100 to prevent gas in the housing cavity 121 from flowing out of the gas-liquid separator 100 through the liquid storage outlet 152. Third, the gas-liquid separator 100 of this application has low noise. Specifically, during the flow of the gas-liquid mixture in the gas-liquid separator 100, the flow velocity of the gas-liquid mixture is highest when it first enters the gas-liquid separator 100. Therefore, the noise generated by the gas-liquid mixture impacting the gas-liquid separator 100 upon entering the gas-liquid separator 100 is also the highest. In the gas-liquid separator 100 of this application, the gas-liquid mixture first enters the separation cylinder assembly 120 from the upper inlet 127, and the separation cylinder assembly 120 is disposed in the housing cavity 121. That is to say, when the gas-liquid mixture impacts the separation cylinder assembly 120, the noise can be effectively blocked by the housing 101, thereby effectively reducing the noise generated by the gas-liquid separator 100. Fourth, the gas-liquid separator 100 of this application has a compact structure and small size. For vertical gas-liquid separators with the same gas-liquid separation efficiency, the height of the gas-liquid separator 100 of this application is only about one-third of its height. For horizontal gas-liquid separators with the same gas-liquid separation efficiency, the volume of the gas-liquid separator 100 of this application is only about half its volume. The smaller size of the gas-liquid separator 100 makes it suitable for applications with low building heights and can also be used in integrated refrigeration units.

[0032] Figure 2 shows an axial cross-sectional view of a gas-liquid separator 200 according to a second embodiment of this application. The gas-liquid separator 200 shown in Figure 2 is substantially the same as the gas-liquid separator 100 shown in Figures 1A-1D. The difference between the gas-liquid separator 200 shown in Figure 2 and the gas-liquid separator 100 shown in Figures 1A-1D is that the lower edge of the outer cylinder 122 of the gas-liquid separator 100 shown in Figures 1A-1D has a lower outlet 130, allowing the lower space 128 to communicate with the liquid storage device 104 through the housing cavity 121. In contrast, the bottom of the outer cylinder 122 of the gas-liquid separator 200 shown in Figure 2 is closed by the housing sidewall 111, and a lower outlet 230 is provided at the housing sidewall 111 that closes the bottom of the outer cylinder 122. The lower outlet 230 is connected to the liquid storage device 104 via a connecting pipe 202. Specifically, the gas-liquid separator 200 also includes a connecting pipe 202. The connecting pipe 202 is located approximately below the housing 101. One end of it is connected to the lower outlet 230, and the other end is connected to the side wall of the liquid storage device 104, so that the liquid accumulated in the lower space 128 can flow into the liquid storage device 104 through the connecting pipe 202.

[0033] The movement path of the gas-liquid mixture in the gas-liquid separator 200 and the gas-liquid separation effect achievable by the gas-liquid separator 200 are roughly the same as those shown in the embodiments of the gas-liquid separator 100 in Figures 1A-1D, and will not be repeated here. The gas-liquid separator 200 is superior to the gas-liquid separator 100 in that the liquid accumulated in the lower space 128 flows into the liquid storage device 104 through the connecting pipe 202, instead of through the housing cavity 121. This arrangement has the advantage that the liquid is less likely to form a liquid surface at the bottom of the housing cavity 121, and it can reduce the disturbance of the liquid by the gas in the housing cavity 121.

[0034] Figure 3 shows an axial cross-sectional view of a gas-liquid separator 300 according to a third embodiment of this application. The gas-liquid separator 300 shown in Figure 3 is substantially the same as the gas-liquid separator 200 shown in Figure 2. The difference between the gas-liquid separator 300 shown in Figure 3 and the gas-liquid separator 200 shown in Figure 2 is that the gas-liquid separator 200 shown in Figure 2 includes a baffle plate 131 and a baffle box 132 to form a flow path that can change the flow path of the fluid flowing from the upper outlet 129 of the separator assembly 120 to the upper outlet 103 of the housing, while the gas-liquid separator 300 shown in Figure 3 includes a baffle pipe 310, a transverse baffle plate 312, and a vertical baffle plate 314 to form a flow path that can change the flow path of the fluid flowing from the upper outlet 129 of the separator assembly 120 to the upper outlet 103 of the housing.

[0035] Specifically, the gas-liquid separator 300 includes a blocking pipe 310, a transverse blocking plate 312, and a vertical blocking plate 314. The blocking pipe 310 extends downward from the top of the housing sidewall 111 around the upper outlet 103 of the housing, forming a blocking opening 301 at its bottom. In this embodiment, the blocking pipe 310 is connected to the outlet pipe 142. The transverse blocking plate 312 is disposed below the blocking pipe 310 and at a certain distance from the blocking opening 301. The vertical blocking plate 314 extends upward from the upper surface of the transverse blocking plate 312. The vertical blocking plate 314 is disposed to the left of the blocking pipe 310 and at a certain distance from it. In other words, in the direction of the axis X of the cylindrical housing sidewall 111, the vertical blocking plate 314 is located between the upper outlet 129 of the separator assembly 120 and the blocking pipe 310. Thus, the blocking tube 310, the horizontal blocking plate 312, and the vertical blocking plate 314 define the passage from the housing cavity 121 to the blocking tube opening 301, so that the gas-liquid mixture can change its direction of movement multiple times, thereby improving the gas-liquid separation rate.

[0036] It should be noted that although the gas-liquid separators 200 and 300 of this application use baffles 131 and baffle boxes 132, as well as baffle pipes 310, horizontal baffles 312 and vertical baffles 314 to form a flow path for the fluid flowing from the upper outlet 129 of the separator assembly 120 to the upper outlet 103 of the housing, those skilled in the art will understand that any baffle disposed in the housing cavity 121 and capable of forming a flow path for the fluid flowing from the upper outlet 129 of the separator assembly 120 to the upper outlet 103 of the housing is within the protection scope of this application.

[0037] Although only some features of this application have been illustrated and described herein, many improvements and variations can be made by those skilled in the art. Therefore, it should be understood that the appended claims are intended to cover all such improvements and variations that fall within the essential spirit of this application.
