Sustainable automated discharge gas-liquid separator for high-pressure gas-liquid product separation

Abstract

This invention discloses a sustainable automatic discharge gas-liquid separator for high-pressure gas-liquid product separation, relating to the field of gas-liquid separator technology. It includes a separation tube with a cavity formed in its inner wall, a liquid level sensor installed at the upper end of the separation tube along its axial direction, and a probe of the liquid level sensor extending into the cavity. An air inlet pipe is fixedly connected to one side of the separation tube. This invention separates the high-pressure gas-liquid products by introducing them into the cavity of the separation tube through the air inlet pipe. Because the gas velocity is lower than the droplet settling velocity, larger droplets quickly fall to the bottom of the cavity under gravity, while smaller droplets rise with the airflow, are intercepted and aggregated upon encountering the separation mesh, forming larger droplets that then settle to the bottom. The gas flows out of the separation tube through the air outlet pipe, thus achieving gas-liquid separation. This structure utilizes gravity separation and separation mesh filtration to improve the separation efficiency of the equipment.

Description

Technical Field

[0001] This invention relates to the field of gas-liquid separator technology, and more specifically to a sustainable automatic discharge gas-liquid separator for high-pressure gas-liquid product separation. Background Technology

[0002] High-pressure gas-liquid products refer to mixtures composed of gaseous and liquid substances under high pressure (usually above 10 MPa, with specific values ​​varying depending on the application). These products are widely found in petrochemical, natural gas extraction, coal chemical, and new energy fields. When separating high-pressure gas-liquid products, gas-liquid separators are typically used to efficiently separate the mixed gas and liquid under high pressure through physical means to meet the safety, economic, and environmental requirements of subsequent processes.

[0003] Chinese invention patent with authorization announcement number "CN116212779A" is specifically entitled "A separation device for a micro-reaction equipment", which includes: a first separation component, including a body, in which a coil is installed, the coil being used to guide the reactants; the first separation component also includes a heat exchanger, which is fixedly connected to the body and is used to exchange heat with the reactants in the coil when there is reactants flowing in the coil; a second separation component, including a heat exchanger and a detection body, the heat exchanger being used to exchange heat with the reactants, the heat exchanger having a through-hole cavity, a first gap being formed between the detection body and the cavity; the second separation component also includes a guide tube, the first end of which is connected to the outlet of the coil, and the second end extending into the first gap in a direction deviating from the axial direction of the heat exchanger, and the guide tube being used to guide the reactants into the first gap.

[0004] The aforementioned patent uses a cyclone-like separation method to achieve gas-liquid separation. When the equipment separates the gas-liquid mixture, the flow rate of the gas-liquid mixture is usually very small, making it difficult to reach the basic speed of cyclone separation. As a result, the separation effect of the device is poor and the separation efficiency is low in actual use, making it inconvenient to use. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a sustainable automatic discharge gas-liquid separator for high-pressure gas-liquid product separation, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sustainable automatic discharge gas-liquid separator for high-pressure gas-liquid product separation, comprising: a separation tube, a cavity formed in the inner wall of the separation tube, a liquid level sensor installed at the upper end of the separation tube, the liquid level sensor being installed axially along the separation tube, the probe of the liquid level sensor extending into the cavity, an air inlet pipe fixedly connected to one side of the separation tube, an air outlet pipe fixedly connected to the other side of the separation tube, a separation mesh installed on one side of the inner wall of the separation tube, the separation mesh being located on one side of the input end of the air outlet pipe, a base installed at the lower end of the separation tube, and a cooling sleeve fitted onto the outer surface of the separation tube.

[0007] As a further preferred embodiment of this technical solution, a liquid outlet is provided through one side of the cooling sleeve, and a liquid inlet is provided through the other side of the cooling sleeve.

[0008] As a further preferred embodiment of this technical solution, the upper end of the base is provided with a drain outlet, which is funnel-shaped.

[0009] As a further preferred embodiment of this technical solution, a wire mesh is installed on the other side of the inner wall of the separation tube, and the wire mesh is located between the probe of the liquid level sensor and the base.

[0010] As a further preferred embodiment of this technical solution, sealing grooves are provided at both the upper and lower ends of the separation tube, and sealing rings are fixedly connected to one side of the base and the liquid level sensor, with the two sealing rings respectively engaging in the two sealing grooves.

[0011] As a further preferred embodiment of this technical solution, a pressure regulating valve is installed at the lower end of the base, and a regulating valve is installed at the lower end of the pressure regulating valve.

[0012] The technical solution provided by this invention has the following advantages compared with the known prior art: This invention separates high-pressure gas-liquid products into the cavity of a separator through an inlet pipe. Because the gas velocity is lower than the droplet settling velocity, larger droplets quickly fall to the bottom of the separator cavity under the influence of gravity, while smaller droplets rise with the airflow. Upon encountering the separation mesh, they are intercepted and aggregated, forming larger droplets that then settle to the bottom. The gas flows out of the separator through an outlet pipe, thus achieving gas-liquid separation. This structure uses gravity separation and separation mesh filtration to improve the separation efficiency of the equipment. Furthermore, this structure is simple, compact, and easy to operate, enhancing the convenience of using the equipment. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] The present invention will be further described below with reference to embodiments.

[0018] This invention provides a technical solution: such as Figure 1 - Figure 5As shown, in this embodiment, a sustainable automatic discharge gas-liquid separator for high-pressure gas-liquid product separation includes: a separation tube 1, a cavity formed in the inner wall of the separation tube 1, a liquid level sensor 16 installed at the upper end of the separation tube 1, the liquid level sensor 16 being installed axially along the separation tube 1, the probe of the liquid level sensor 16 extending into the cavity, an air inlet pipe 12 fixedly connected to one side of the separation tube 1, an air outlet pipe 11 fixedly connected to the other side of the separation tube 1, a separation mesh 17 installed on one side of the inner wall of the separation tube 1, and the separation mesh 17 being located on one side of the input end of the air outlet pipe 11, a base 13 installed at the lower end of the separation tube 1, and a cooling sleeve 2 sleeved on the outer surface of the separation tube 1.

[0019] By introducing the high-pressure gas-liquid products into the cavity of the separation tube 1 through the inlet pipe 12, the larger droplets quickly fall to the bottom of the cavity of the separation tube 1 due to the lower gas velocity than the droplet settling velocity under the action of gravity, while a small number of tiny droplets rise with the airflow and are intercepted and gathered after encountering the separation mesh 17, forming large droplets that then settle to the bottom. The gas then flows out of the separation tube 1 through the outlet pipe 11, thus achieving gas-liquid separation. This structure allows the separation equipment to use gravity separation and filtration by the separation mesh 17, improving the separation efficiency of the equipment. Moreover, this structure is simple, small in size, and easy to operate, improving the convenience of using the equipment.

[0020] like Figure 1 - Figure 3 As shown, a liquid outlet 21 is provided through one side of the cooling sleeve 2, and a liquid inlet 22 is provided through the other side of the cooling sleeve 2; the liquid outlet 21 and the liquid inlet 22 work together to allow cooling water to circulate inside the cooling sleeve 2, ensuring that the high-pressure gas-liquid products enter the cavity of the separation tube 1 and are condensed and liquefied.

[0021] like Figure 3 and Figure 5 As shown, a drain port 5 is provided through the upper end of the base 13. The drain port 5 is funnel-shaped. The structural design of the drain port 5 makes the contact surface between the base 13 and the liquid funnel-shaped, which facilitates the drainage of accumulated liquid.

[0022] like Figure 2 , Figure 3 and Figure 5 As shown, a wire mesh 3 is installed on the other side of the inner wall of the separation tube 1. The wire mesh 3 is located between the probe of the liquid level sensor 16 and the base 13. The wire mesh 3 is used to prevent the reaction products from clogging the downstream pipeline of the separation tube 1.

[0023] like Figure 3 and Figure 4As shown, sealing grooves 41 are provided at both the upper and lower ends of the separation tube 1. Sealing rings 4 are fixedly connected to one side of the base 13 and the liquid level sensor 16. The two sealing rings 4 are respectively snapped into the two sealing grooves 41. The structural design of the sealing rings 4 and the sealing grooves 41 ensures that the gap between the separation tube 1 and the liquid level sensor 16 and the base 13 is sealed, ensuring that the equipment can separate high-pressure gas and liquid and prevent leakage.

[0024] like Figure 1 As shown, a pressure regulating valve 14 is installed at the lower end of the base 13, and a regulating valve 15 is installed at the lower end of the pressure regulating valve 14. The pressure regulating valve 14 can adjust the high-pressure liquid to normal pressure before releasing it. When the inlet liquid is at normal pressure, the pressure regulating valve 14 can continue to be used or can be canceled. The regulating valve 15 works in conjunction with the liquid level sensor 16. The liquid level signal fed back by the liquid level sensor 16 adjusts the opening of the valve 15 in real time to keep the liquid level in a stable state, so that the inlet flow rate and the outlet flow rate of the system are consistent, thereby realizing high-pressure continuous liquid discharge.

[0025] It is important to note that when the equipment is started, the regulating valve 15 is in the closed state; as the reaction proceeds, the droplets at the bottom accumulate, and the liquid level sensor 16 will feed back the detected liquid level signal to the regulating valve 15 at the bottom.

[0026] This invention provides a sustainable automatic discharge gas-liquid separator for high-pressure gas-liquid product separation, the specific working principle of which is as follows: When separating high-pressure gas-liquid products, the high-pressure gas-liquid products first enter the cavity of the separator tube 1 through the inlet pipe 12. At the same time, the coolant enters the cooling sleeve 2 from the inlet 22 and exits from the outlet 21. The coolant enters the cooling sleeve 2 to exchange heat with the separator tube 1. Since the gas flow rate is lower than the droplet settling velocity, under the action of gravity, the larger droplets quickly fall to the bottom of the cavity of the separator tube 1, while a small number of tiny droplets rise with the airflow. After encountering the separation wire mesh 17, they are intercepted and gathered, forming large droplets that then settle to the bottom. The gas flows out of the separator tube 1 through the outlet pipe 11, thus achieving gas-liquid separation. The pressure regulating valve 14 adjusts the high-pressure or normal-pressure liquid to normal-pressure liquid flow, and then the regulating valve 15 controls the stable liquid discharge.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
