Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separation devices, specifically a gas-liquid mixture recovery device. Background Technology

[0002] Gas-liquid separation devices effectively separate gas and liquid in gas-liquid mixtures through physical principles such as gravity settling, inertial separation, wire mesh or filtration separation, achieving resource recovery, environmental protection and equipment protection. They are widely used in oil and gas, refrigeration, chemical, food processing and environmental protection fields. The design of the device needs to consider the characteristics of the medium, operating conditions and separation efficiency requirements. Common structures include vertical and horizontal structures.

[0003] Traditional gas-liquid separation devices used for gas-liquid mixture recovery can effectively separate the gas-liquid mixture, enabling the gas or liquid to be reused. However, in actual operation, some solid impurity particles will be mixed in the gas-liquid mixture. Traditional gas-liquid separation devices have difficulty effectively separating these solid particles. Therefore, the inventors urgently need to design a gas-liquid separation device with solid particle separation capabilities to ensure that the separated gas and liquid have the value of secondary utilization. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a gas-liquid mixture recovery device to solve the technical problem that traditional gas-liquid separation devices mainly rely on the density difference, inertia or particle size difference between the gas and liquid phases to achieve separation. Their original design was for gas-liquid mixtures. However, when the mixture contains solid impurity particles, these devices have obvious shortcomings.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas-liquid mixture recovery device, comprising a separation device, the separation device comprising a separation tank body, an inlet pipe provided on one side of the interior of the separation tank body, an overflow cylinder fixedly provided at the lower axis of the interior of the separation tank body, a cavity formed between the outer side of the overflow cylinder and the interior of the separation tank body, the outlet end of the inlet pipe extending into the interior of the overflow cylinder, a liquid outlet and a drain outlet welded to the lower part of the separation tank body, the liquid outlet communicating with the cavity for discharging liquid substances, and the drain outlet communicating with the overflow cylinder for discharging solid substances.

[0006] By adopting the above technical solution, efficient separation of gas, liquid and solid phases is achieved. The feed pipe extends directly into the overflow cylinder, allowing the mixture to undergo initial settling in the confined space. The gas rises naturally due to the density difference and is discharged through the top gas outlet, while the liquid overflows evenly into the cavity through the overflow teeth. The solid particles gradually settle to the bottom of the overflow cylinder due to their higher density, preventing the particles from escaping with the liquid.

[0007] Furthermore, the overflow cylinder is fixedly connected to the inner wall of the separator body by several reinforcing rods, and a support leg is welded to the bottom of the separator body.

[0008] By adopting the above technical solution, the reinforcing rod firmly connects the overflow cylinder to the inner wall of the separator, which greatly enhances the structural stability of the overflow cylinder, prevents it from vibrating or shifting under high-speed fluid impact or pressure fluctuations, and ensures the safety and reliability of the separation process.

[0009] Furthermore, the lower inner side of the overflow cylinder is sloped, and a plurality of overflow teeth are formed in a ring array above the overflow cylinder.

[0010] By adopting the above technical solution, the inclined surface design on the lower inner side of the overflow cylinder greatly promotes the collection and guidance of solid particles. The settled particles can slide down the inclined surface to the center area of ​​the bottom of the cylinder, effectively preventing particles from accumulating in the corners and ensuring that they can be smoothly discharged through the drain outlet, reducing the frequency of cleaning and maintenance.

[0011] Furthermore, the feed end of the feed pipe is located above or on one side of the main body of the separator, and an outlet is welded to the top of the main body of the separator for discharging gaseous substances.

[0012] By adopting the above technical solution, the feed end of the feed pipe is set above or to one side of the main body of the separator, providing a flexible equipment interface design scheme. The inlet direction can be flexibly selected according to the actual process flow and site layout, which facilitates connection with upstream pipelines and reduces installation complexity and cost.

[0013] Furthermore, a first inspection port and a second inspection port are welded to one side of the main body of the separation tank.

[0014] By adopting the above technical solution, the first and second inspection ports greatly facilitate the internal inspection, cleaning and maintenance of the equipment. Operators can directly access the cavity and the external area of ​​the overflow cylinder through the inspection ports to complete maintenance work without disassembling the entire tank, which significantly reduces the difficulty, time and cost of equipment maintenance.

[0015] Furthermore, two sets of connecting pipes are welded to one side of the main body of the separation tank. The connecting pipes are connected to the cavity, and a flap level gauge is installed at the outer end of the connecting pipes.

[0016] By adopting the above technical solution, the flap level gauge enables real-time and intuitive monitoring of the liquid level in the cavity. Operators can accurately grasp the liquid level height during the separation process, thereby adjusting the feeding or discharging operation in a timely manner. This prevents gas from entering the liquid path due to excessively high liquid level or gas from escaping from the drain port due to excessively low liquid level, ensuring the stability and efficiency of the separation process.

[0017] Furthermore, the discharge end of the feed pipe is provided with a buffer mechanism, which includes an umbrella-shaped buffer plate for buffering the mixture. The buffer plate is fixedly connected to the feed pipe through several connecting rods.

[0018] By adopting the above technical solution, the umbrella-shaped buffer plate in the buffer mechanism can effectively intercept the high-speed inflow of the mixture, greatly reduce the fluid kinetic energy by diffusing the impact area, avoid the direct impact of the incoming flow on the liquid surface causing violent disturbance or resuspension of settled particles, and create a stable environment for subsequent static settling.

[0019] In summary, the present invention has the following main advantages: This invention achieves efficient three-phase separation of gas, liquid, and solid through a cavity structure formed by the overflow cylinder and the main body of the separator. The feed pipe leads directly into the overflow cylinder. After the mixture is slowed down by the buffer mechanism, the gas naturally floats up and is discharged from the top outlet. The liquid overflows evenly into the cavity through the overflow teeth, and the solid particles settle under gravity. At the same time, an independent drain outlet is directly connected to the bottom of the overflow cylinder to discharge the deposited solid impurities, completely solving the clogging problem caused by solid accumulation in traditional devices and significantly improving the separation purity and equipment operation stability.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In this embodiment: A gas-liquid mixture recovery device, such as Figure 1-4 As shown, the device includes a separation unit 1, which comprises a separation tank body 101. A feed pipe 102 is provided on one side of the interior of the separation tank body 101. An overflow cylinder 103 is fixedly installed at the lower axis of the interior of the separation tank body 101. A cavity 104 is formed between the outer side of the overflow cylinder 103 and the interior of the separation tank body 101. The discharge end of the feed pipe 102 extends into the interior of the overflow cylinder 103. A liquid outlet 107 and a drain outlet 108 are welded to the lower part of the separation tank body 101. The liquid outlet 107 is connected to the cavity 104 and is used to discharge liquid substances. The drain outlet 108 is connected to the overflow cylinder 103 and is used to discharge solid substances, thus achieving efficient separation of gas, liquid, and solid phases. The feed pipe 102 extends directly into the overflow cylinder, allowing the mixture to undergo initial settling within the confined space. Gas rises naturally due to density difference and is discharged through the top air outlet 109, while liquid overflows evenly into the cavity 104 through the overflow teeth 106. Solid particles, due to their higher density, gradually settle to the bottom of the overflow cylinder 103, preventing them from escaping with the liquid. Meanwhile, the liquid outlet 107 is connected to the cavity to ensure that only pure liquid is discharged. The drain outlet 108 is directly connected to the bottom of the overflow cylinder and is specifically used to collect and discharge settled solid impurities. This fundamentally solves the clogging problem caused by solid accumulation in traditional separation devices, significantly improving separation purity and the long-term stability of the equipment.

[0024] See Figure 1 , Figure 2 , Figure 3 The overflow cylinder 103 is fixedly connected to the inner wall of the separation tank body 101 by several reinforcing rods 105. A support leg 3 is welded to the bottom of the separation tank body 101. The reinforcing rods 105 firmly connect the overflow cylinder 103 to the inner wall of the separation tank body 101, which greatly enhances the structural stability of the overflow cylinder and prevents it from vibrating or shifting under high-speed fluid impact or pressure fluctuations, ensuring the safety and reliability of the separation process. At the same time, the support leg 3 not only provides a stable foundation support for the entire device and adapts to the needs of different installation environments, but also provides sufficient operating and maintenance space for the bottom drain port 108 and liquid outlet 107 by raising the height of the tank, which facilitates the connection of pipelines and the installation of discharge valves.

[0025] See Figure 1 , Figure 2 , Figure 3The inner lower part of the overflow cylinder 103 is set with an incline, and several overflow teeth 106 are formed in a ring array above the overflow cylinder 103. The incline design of the inner lower part of the overflow cylinder 103 greatly promotes the collection and guidance of solid particles. The settled particles can slide down the incline to the center area of ​​the bottom of the cylinder, effectively preventing particles from accumulating in corners and ensuring that they can be smoothly discharged through the drain port 108, reducing the frequency of cleaning and maintenance. At the same time, the overflow teeth 106 in the ring array above the cylinder allow the liquid to overflow into the cavity 104 evenly and smoothly, which not only improves the solid-liquid separation efficiency, but also reduces the secondary entrainment of fine particles and ensures the relative purity of the overflow liquid.

[0026] See Figure 1 , Figure 2 , Figure 3 The feed end of the feed pipe 102 is located above or to one side of the separator body 101. An outlet 109 is welded to the top of the separator body 101 for discharging gaseous substances. Setting the feed end of the feed pipe 102 above or to one side of the separator body 101 provides a flexible equipment interface design scheme. The inlet direction can be flexibly selected according to the actual process flow and site layout, which facilitates connection with upstream pipelines and reduces installation complexity and cost. At the same time, welding the outlet 109 at the top of the separator body 101 conforms to the physical law of natural gas rise, providing the shortest and smoothest discharge channel for the separated gas, effectively reducing the residence time and pressure loss of gas in the tank, ensuring the efficiency and purity of gas recovery, and the overall layout is scientific and reasonable.

[0027] See Figure 1 , Figure 2 , Figure 3 The separation tank body 101 is welded with a first inspection port 202 and a second inspection port 203 on one side. The first inspection port 202 and the second inspection port 203 greatly facilitate the internal inspection, cleaning and maintenance of the equipment. Operators can directly access the external areas of the cavity 104 and the overflow cylinder 103 through the inspection ports to complete the maintenance work without disassembling the entire tank. This significantly reduces the difficulty, time and cost of equipment maintenance. At the same time, the setting of the dual inspection ports allows for separate inspection of different areas of the equipment, which improves the pertinence and efficiency of maintenance work, ensures the long-term stable operation of the equipment and extends its service life.

[0028] See Figure 1 , Figure 2 , Figure 3Two sets of connecting pipes 201 are welded to one side of the main body 101 of the separator. The connecting pipes 201 are connected to the cavity 104. The outer end of the connecting pipes 201 is connected to a flap level gauge. The flap level gauge enables real-time and intuitive monitoring of the liquid level in the cavity. The operator can accurately grasp the liquid level during the separation process, so as to adjust the feeding or discharging operation in time, and prevent the liquid level from being too high, causing gas to enter the liquid path, or the liquid level from being too low, causing gas to escape from the drain port. This ensures the stability and efficiency of the separation process. At the same time, this setting provides a foundation for future automated control, and improves the intelligence level and ease of operation of the equipment.

[0029] See Figure 2 , Figure 3 , Figure 4 The feed pipe 102 is equipped with a buffer mechanism 4 at its outlet end. The buffer mechanism 4 includes an umbrella-shaped buffer plate 401 for buffering the mixture. The buffer plate 401 is fixedly connected to the feed pipe 102 by several connecting rods 402. The umbrella-shaped buffer plate 401 in the buffer mechanism 4 can effectively intercept the high-speed inflow of the mixture. By diffusing the impact area, it greatly reduces the fluid kinetic energy and avoids the incoming flow from directly impacting the liquid surface, causing violent disturbance or resuspension of settled particles. This creates a stable environment for subsequent static settling. At the same time, the buffer mechanism is fixed by the connecting rods 402. The structure is simple and reliable. It not only protects the internal components of the tank from erosion and wear, but also promotes the pre-separation of the gas, liquid and solid phases by reducing the initial momentum, further improving the overall separation efficiency and purity of the entire device.

[0030] The implementation principle of this embodiment is as follows: The gas-liquid-solid mixture enters the overflow cylinder 103 of the separation device 1 through the feed pipe 102. It first impacts the umbrella-shaped buffer plate 401 of the buffer mechanism 4 to decelerate and initially disperse the mixture. The mixture remains still or rises slowly in the overflow cylinder 103. The gas, being less dense, naturally floats up and is discharged through the top air outlet 109. After the liquid level rises to the overflow teeth 106 on the upper edge of the overflow cylinder 103, it overflows into the cavity 104 formed by the overflow cylinder 103 and the inner wall of the separation tank body 101. In the wide space of the cavity 104, the liquid flow rate is significantly reduced. The solid impurities entrained therein completely settle to the bottom of the overflow cylinder 103 under the action of gravity. Finally, the pure liquid is discharged and recovered from the liquid outlet 107 connected to the cavity 104, while the solid particles deposited at the bottom are periodically discharged through the drain outlet 108 connected to the bottom of the overflow cylinder 103, thereby achieving efficient separation and recovery of the gas, liquid and solid three phases.
