[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0034] Below with reference to Figure 1 Describe the gas-liquid separator 100 according to an embodiment of the present invention. The gas-liquid separator 100 is suitable for measuring the liquid level in a container 10 with solid substances (such as dust or metal precipitates).

[0035] As Figure 1 shown, the gas-liquid separator 100 according to an embodiment of the present invention includes: a container 10, a gas-phase pressure tapping hole 111 is formed on the top wall 11 of the container 10, a liquid-phase pressure tapping hole 121 is formed on the bottom wall 12 of the container 10; a liquid level detector 20, the liquid level detector 20 has a first interface 21 and a second interface 22, the first interface 21 is adapted to communicate with the gas-phase pressure tapping hole 111, a connection port 71 is formed on the side wall of the liquid-phase pressure tapping hole 121, the connection port 71 is adapted to communicate the second interface 22 and the liquid-phase pressure tapping hole 121, and the liquid level detector 20 is used to detect the liquid level height in the container 10; a substance collector 40, the substance collector 40 is connected to the end of the liquid-phase pressure tapping hole 121 away from the container 10 so that solid substances in the container 10 flow into the substance collector 40.

[0036] Among them, the container 10 can define a receiving cavity 13 for receiving a gas-liquid mixture. The gas-liquid separation of the gas-liquid mixture is carried out inside the container 10. The gas in the receiving cavity 13 moves upward in the container 10, and the liquid in the receiving cavity 13 is located at the lower part inside the container 10. The top wall 11 of the container 10 is the top wall 11 of the receiving cavity 13. A gas-phase pressure tapping hole 111 is formed on the top wall 11 of the container 10. The gas-phase pressure tapping hole 111 communicates with the receiving cavity 13, and the gas in the receiving cavity 13 can move to the gas-phase pressure tapping hole 111. The bottom wall 12 of the container 10 is the bottom wall 12 of the receiving cavity 13. A liquid-phase pressure tapping hole 121 is formed on the bottom wall 12 of the container 10. The liquid-phase pressure tapping hole 121 communicates with the receiving cavity 13. The liquid in the receiving cavity 13 can flow to the liquid-phase pressure tapping hole 121. The liquid level detector 20 is used to detect the liquid level height inside the container 10. The liquid level detector 20 can be a liquid level gauge, a differential pressure transmitter, etc. The type of the liquid level detector 20 is not specifically limited as long as the liquid level detector 20 can detect the liquid level height inside the container 10. The liquid level detector 20 has a first interface 21 and a second interface 22. The first interface 21 is a low-pressure side interface, and the second interface 22 is a high-pressure side interface. The pressure connected to the first interface 21 is less than the pressure connected to the second interface 22. The first interface 21 is adapted to communicate with the gas-phase pressure tapping hole 111, and the first interface 21 selectively communicates with the gas-phase pressure tapping hole 111. The first interface 21 can communicate with the gas-phase pressure tapping hole 111 through a first pipeline 80, so that the first interface 21 is indirectly connected to the gas-phase pressure tapping hole 111. The first interface 21 can also be directly connected to the gas-phase pressure tapping hole 111. A connection port 71 is formed on the side wall of the liquid-phase pressure tapping hole 121. The connection port 71 is adapted to connect the second interface 22 and the liquid-phase pressure tapping hole 121. The connection port 71 communicates with the liquid-phase pressure tapping hole 121, and the connection port 71 can selectively communicate with the second interface 22. The second interface 22 can also communicate with the connection port 71 through a second pipeline 90, so that the second interface 22 is indirectly connected to the connection port 71. The second interface 22 can also be directly connected to the connection port 71.

[0037] The capacity of the substance collector 40 can be reasonably selected according to the estimated amount of solid substances, and as much margin as possible should be left. The substance collector 40 is connected to the end of the liquid-phase pressure tapping hole 121 away from the container 10. The substance collector 40 selectively communicates with the liquid-phase pressure tapping hole 121. That is to say, the substance collector 40 can communicate with the liquid-phase pressure tapping hole 121, and the substance collector 40 can also be not connected to the liquid-phase pressure tapping hole 121. When the substance collector 40 communicates with the liquid-phase pressure tapping hole 121, the liquid in the receiving cavity 13 flows into the substance collector 40. When there are solid substances mixed in the liquid in the receiving cavity 13, the solid substances can flow into the substance collector 40. The solid substances can be impurities such as dust and metal powder.

[0038] When the liquid level detector 20 detects the liquid level height in the container 10, the gas in the container 10 flows to the first interface 21 through the gas phase pressure taking hole 111, and the liquid level detector 20 obtains the gas pressure value in the container 10 through the gas phase pressure taking hole 111. The liquid in the container 10 flows to the second interface 22 through the liquid phase pressure taking hole 121, and the liquid level detector 20 obtains the liquid pressure value in the container 10 through the liquid phase pressure taking hole 121. The liquid level detector 20 calculates the liquid level height in the container 10 through the difference between the liquid pressure value and the gas pressure value.

[0039] Furthermore, if there is solid matter inside the container 10, it will be concentrated at the bottom of the container 10. Since the side wall of the liquid phase pressure taking hole 121 forms the connection port 71, and the material collector 40 is connected to the end of the liquid phase pressure taking hole 121 away from the container 10, when the solid matter flows to the liquid phase pressure taking hole 121 along with the liquid, the solid matter flows into the material collector 40 along the liquid phase pressure taking hole 121 under the action of gravity, and the solid matter is stored in the material collector 40. Compared with the prior art, the risk of solid matter flowing to the second interface 22 is reduced, thereby reducing the risk of blockage of the second interface 22 and the second pipeline 90, thereby improving the accuracy of liquid level measurement.

[0040] Therefore, by setting up the material collector 40, when the liquid level detector 20 measures the liquid level height in the container 10, the solid matter flowing out of the liquid phase pressure taking hole 121 can flow into the material collector 40, reducing the risk of the solid matter flowing into the second interface 22, thereby improving the accuracy of the liquid level measurement.

[0041] In some examples of the present invention, Figure 1 As shown, the bottom wall 12 of the container 10 may include: a vertical tube 70 , which is annular to define a liquid phase pressure taking hole 121 , and the vertical tube 70 forms a connecting port 71 , and the material collector 40 is connected to the lower end of the vertical tube 70 .

[0042] Among them, the vertical pipe 70 can be located outside the accommodation chamber 13. The vertical pipe 70 is configured as an annular pipe, and the vertical pipe 70 extends along the height direction of the container 10, or the vertical pipe 70 extends substantially along the height direction of the container 10. The vertical pipe 70 defines a liquid-phase pressure tapping hole 121. The upper end of the vertical pipe 70 is connected to the bottom wall 12 of the container 10. The vertical pipe 70 forms a connection port 71. The connection port 71 is located between the upper end and the lower end of the vertical pipe 70. The material collector 40 is connected to the lower end of the vertical pipe 70. The material collector 40 can be directly connected to the lower end of the vertical pipe 70, or the material collector 40 can also be indirectly connected to the lower end of the vertical pipe 70 through other components, so that the material collector 40 can communicate with the liquid-phase pressure tapping hole 121. By providing the vertical pipe 70, connecting the material collector 40 to the lower end of the vertical pipe 70, and having the connection port 71 located between the upper end and the lower end of the vertical pipe 70, when the solid material flows with the liquid to the liquid-phase pressure tapping hole 121, it is more conducive to the solid material flowing into the material collector 40 along the liquid-phase pressure tapping hole 121 under the action of gravity, further reducing the risk of the solid material flowing to the second interface 22, thereby further reducing the risk of blockage of the second interface 22 and the second pipeline 90, and further improving the accuracy of liquid level measurement.

[0043] In some examples of the present invention, such as Figure 1 As shown, the gas-liquid separator 100 may further include: a control valve 50, and the control valve 50 is connected between the material collector 40 and the liquid-phase pressure tapping hole 121 to selectively communicate the material collector 40 with the liquid-phase pressure tapping hole 121.

[0044] Among them, the control valve 50 can be configured as a ball valve, a cut-off valve, etc. In this application, the control valve 50 is configured as a ball valve as an example for illustration. The control valve 50 is connected between the collector inlet 41 of the material collector 40 and the liquid-phase pressure tapping hole 121. The control valve 50 can control whether the collector inlet 41 and the liquid-phase pressure tapping hole 121 are communicated. By adjusting the control valve 50, the material collector 40 can be selectively communicated with the liquid-phase pressure tapping hole 121. The control valve 50 can be configured as a manual regulating valve, or the control valve 50 can also be configured as an electric regulating valve. When the liquid level detector 20 detects the liquid level height in the container 10, the control valve 50 is in an open state all the time. At this time, the collector inlet 41 and the liquid-phase pressure tapping hole 121 are communicated. When the solid material flows with the liquid to the liquid-phase pressure tapping hole 121, the solid material can flow into the material collector 40 along the liquid-phase pressure tapping hole 121 and the control valve 50 under the action of gravity.

[0045] In some examples of the present invention, such as Figure 1 As shown, the material collector 40 is formed with a collector inlet 41, and the collector inlet 41 is adapted to communicate with the liquid-phase pressure tapping hole 121.

[0046] Among them, the collector inlet 41 can be formed at the top of the material collector 40. As an example, the collector inlet 41 can be directly communicated with the liquid-phase pressure tapping hole 121. As another example, the control valve 50 can be connected between the collector inlet 41 and the liquid-phase pressure tapping hole 121. The control valve 50 can control the communication or non-communication between the collector inlet 41 and the liquid-phase pressure tapping hole 121. In this solution, the collector inlet 41 is indirectly communicated with the liquid-phase pressure tapping hole 121 through the control valve 50. With the collector inlet 41 formed in the material collector 40, when the solid material flows towards the liquid-phase pressure tapping hole 121 along with the liquid, the solid material can flow into the material collector 40.

[0047] In some examples of the present utility model, as Figure 1 shown, the material collector 40 may include: a collector body 42 and a cover body 43. The collector body 42 defines a material storage space 421. The collector body 42 is formed with a collector inlet 41 and a material discharge port 422. Both the collector inlet 41 and the material discharge port 422 are communicated with the material storage space 421. The cover body 43 is detachably mounted on the collector body 42 to open or close the material discharge port 422.

[0048] Among them, the material collector 40 may include a collector body 42 and a cover body 43. The collector body 42 may be annular to define a material storage space 421. The collector body 42 is formed with a collector inlet 41 and a material discharge port 422. Both the collector inlet 41 and the material discharge port 422 are communicated with the material storage space 421. The cover body 43 can be snap-connected to the collector body 42. The cover body 43 can also be adhesively bonded to the collector body 42. The cover body 43 can also be assembled to the collector body 42 by screw fit. For example: the material discharge port 422 is formed with an internal thread, and the side wall of the cover body 43 is formed with an external thread. The cover body 43 is assembled at the material discharge port 422, and the external thread of the cover body 43 and the internal thread of the material discharge port 422 are threadedly connected, so that the cover body 43 is detachably mounted on the collector body 42. When the cover body 43 is mounted on the collector body 42, the cover body 43 closes the material discharge port 422. When the cover body 43 is removed from the collector body 42, the cover body 43 opens the material discharge port 422.

[0049] This application will be described by taking the control valve 50 connected between the material collector 40 and the liquid-phase pressure tapping hole 121 as an example. When it is necessary to clean the solid materials in the material storage space 421 of the material collector 40, the control valve 50 is closed to disconnect the material collector 40 from the liquid-phase pressure tapping hole 121. At this time, the liquid level detector 20 can normally detect the liquid level height in the container 10. Then, the cover body 43 is removed to open the material discharge port 422, and the solid materials in the material storage space 421 of the material collector 40 are cleaned through the material discharge port 422. After the cleaning is completed, the cover body 43 is installed on the collector body 42 to close the material discharge port 422. Then, the control valve 50 is slowly opened to allow the liquid at the liquid-phase pressure tapping hole 121 to slowly flow into the material collector 40, reducing the impact on the entire system caused by the liquid level fluctuation in the container 10 and further improving the liquid level measurement accuracy.

[0050] In some examples of the present utility model, as Figure 1 shown, the collector inlet 41 and the material discharge port 422 are arranged along the height direction of the material collector 40, and the collector inlet 41 is located above the material discharge port 422.

[0051] Among them, the height direction of the material collector 40 is Figure 1 the Z direction in

[0052] In some examples of the present utility model, as Figure 1 shown, the surface of the cover body 43 facing the material storage space 421 may be provided with a buffer layer. Among them, the buffer layer may be made of buffer materials such as foam and rubber, and the buffer layer has a buffering effect. By arranging the buffer layer on the surface of the cover body 43 facing the material storage space 421, when the solid materials flow into the material collector 40 from the collector inlet 41 and fall on the buffer layer, the buffer layer can play a buffering role, which can reduce the force on the cover body 43 and reduce the risk of the cover body 43 loosening due to long-term force.

[0053] In some examples of the present utility model, such as Figure 1 shown, the collector body 42 is formed with an observation window 423. Among them, a part of the collector body 42 is formed with the observation window 423, and the observation window 423 can be arranged around the collector body 42 along the circumferential direction of the collector body 42. By providing the observation window 423, the staff can observe the accumulation situation of solid substances in the material storage space 421 through the observation window 423, and the staff can make an intuitive judgment on the accumulation situation of solid substances in the material storage space 421.

[0054] In some examples of the present utility model, there are multiple observation windows 423, and the multiple observation windows 423 are distributed at different positions of the collector body 42. Among them, the multiple observation windows 423 can be arranged at different heights of the collector body 42, and the multiple observation windows 423 can also be arranged in sequence along the circumferential direction of the collector body 42. However, the present utility model is not limited thereto, and the specific positions of the multiple observation windows 423 can be reasonably selected and arranged according to actual situations. By providing the multiple observation windows 423, the staff can observe the accumulation situation of solid substances in the material storage space 421 through the observation windows 423 at different positions, so that the staff can better understand the accumulation situation of solid substances in the material storage space 421.

[0055] In some examples of the present utility model, the cover body 43 and the collector body 42 are assembled by screw-thread fitting. As an example, an internal thread is formed at the material discharge port 422, an external thread is formed on the side wall of the cover body 43, the cover body 43 is assembled at the material discharge port 422, and the external thread of the cover body 43 and the internal thread of the material discharge port 422 are threadedly connected, so that the cover body 43 can be detachably installed on the collector body 42, and the cover body 43 can be disassembled and assembled by rotating the cover body 43. As another example, an external thread is formed on the outer peripheral wall of the collector body 42, an installation wall is formed at the edge of the cover body 43, the installation wall is annular and arranged along the edge of the cover body 43, and an internal thread is formed on the inner side wall of the installation wall. When the cover body 43 is assembled with the collector body 42, the installation wall is sleeved on the collector body 42, and the external thread of the collector body 42 and the internal thread of the installation wall are assembled by screw-thread, so that the cover body 43 can be fixedly assembled with the collector body 42. When it is necessary to remove the cover body 43, the cover body 43 is twisted, and the cover body 43 can be removed. Thus, by the screw-thread fitting of the cover body 43 and the collector body 42, the disassembly and assembly of the cover body 43 are facilitated, and thus it is more convenient to clean the solid substances in the material storage space 421. It should be noted that the cleaning of the solid substances in the material storage space 421 can be carried out online, and the equipment does not need to stop running.

[0056] In some examples of the present utility model, the installation height of the second interface 22 is equal to that of the connection port 71. Wherein, along the height direction of the container 10, the installation height of the second interface 22 is equal to that of the connection port 71, which can also be understood as that the installation height of the second interface 22 is basically equal to that of the connection port 71. By setting the installation height of the second interface 22 to be equal to that of the connection port 71, it is beneficial to improve the liquid level measurement accuracy of the liquid level detector 20.

[0057] It should be noted that when the installation height of the second interface 22 is equal to the installation height of the bottom wall 12 of the container 10, the liquid level measurement of the liquid level detector 20 is the most accurate. In the embodiments of the present application, since the connection port 71 is located below the bottom wall 12 of the container 10 and there is a certain height difference between the connection port 71 and the bottom wall 12 of the container 10, when using the liquid level detector 20 to measure the liquid level height, calibration is pre - carried out on the liquid level detector 20 to perform zero - point migration to compensate for the influence of the height difference between the connection port 71 and the bottom wall 12 of the container 10 on the measurement result, thereby being beneficial to improving the liquid level measurement accuracy of the liquid level detector 20.

[0058] In some examples of the present utility model, as Figure 1 shown, the gas - liquid separator 100 may further include: a mounting bracket 60, and the liquid level detector 20 is fixedly arranged on the mounting bracket 60. Wherein, the liquid level detector 20 can be installed on the mounting bracket 60 by bolts, and the liquid level detector 20 can also be clamped on the mounting bracket 60. By fixedly arranging the liquid level detector 20 on the mounting bracket 60, the position of the liquid level detector 20 can be made stable, reducing the influence of the shaking of the liquid level detector 20 on the liquid level measurement result, and further improving the liquid level measurement accuracy of the liquid level detector 20.

[0059] In some examples of the present utility model, as Figure 1 shown, the gas - liquid separator 100 may further include: a first valve 91, the first valve 91 is connected between the connection port 71 and the second interface 22, and the first valve 91 can be a cut - off valve, a ball valve, etc. Further, a second pipeline 90 is connected between the first valve 91 and the second interface 22, and the first valve 91 is connected between the second pipeline 90 and the connection port 71. By adjusting the opening or closing of the first valve 91, the connection port 71 can be selectively communicated with the second interface 22. It should be noted that when the liquid level detector 20 detects the liquid level height in the container 10, the first valve 91 is in an open state all the time.

[0060] In some examples of the present utility model, as Figure 1As shown, the gas-liquid separator 100 may further include: a second valve 92, which is connected between the gas-phase pressure tapping hole 111 and the first interface 21. The second valve 92 may be a shut-off valve, a ball valve, etc. Further, the first pipeline 80 is connected between the second valve 92 and the first interface 21, and the second valve 92 is connected between the first pipeline 80 and the gas-phase pressure tapping hole 111. By adjusting the opening or closing of the second valve 92, the gas-phase pressure tapping hole 111 can be selectively communicated with the first interface 21. It should be noted that when the liquid level detector 20 detects the liquid level height in the container 10, the second valve 92 is in an open state all the time.

[0061] Next, according to Figure 1 a detailed description will be given of an embodiment of the gas-liquid separator 100 of the present application.

[0062] The gas-liquid separator 100 includes a container 10, a liquid level detector 20, a substance collector 40, a first valve 91, a second valve 92, a mounting bracket 60, a first pipeline 80, a second pipeline 90, a vertical pipe 70, and a control valve 50. A gas-phase pressure tapping hole 111 is formed on the top wall 11 of the container 10. The first pipeline 80 is connected between the second valve 92 and the first interface 21, and the second valve 92 is connected between the first pipeline 80 and the gas-phase pressure tapping hole 111.
