Description

Technical Field

[0001] The utility model relates to the technical field of shale gas development, in particular to a gas-liquid separation device based on shale gas development. Background Art

[0002] Shale gas-liquid separation is an important link in the shale gas extraction and production process. It aims to effectively separate the gas and liquid in shale gas to improve the purity and utilization efficiency of shale gas. During the shale gas extraction process, due to the influence of various factors such as geological conditions and extraction technology, the produced shale gas often contains a certain amount of water and other impurities. If these liquid components directly enter the pipeline or equipment with the gas, it will not only reduce the calorific value and quality of the shale gas, but also cause corrosion and blockage to the pipeline and equipment, increasing maintenance costs and safety risks.

[0003] For example, the patent application number disclosed on the China Patent Network is: 201822277342.4, and the patent name is: A gas-liquid separation device based on shale gas development, comprising a vertical separator, a pipeline assembly and a buffer connected in sequence, the vertical separator comprising a gas-liquid inlet assembly arranged on the side wall, an exhaust port arranged on the top and a liquid discharge port arranged on the bottom, wherein the liquid discharge port is connected to the pipeline assembly; a first outlet and a second outlet are provided at the end of the pipeline assembly, and both the first outlet and the second outlet are connected to the buffer; a liquid collecting port and a gas collecting port are provided on the buffer. In this application, the first separation is first performed by a vertical separator, and the gas-liquid mixture that has not been completely separated enters the pipeline assembly again for separation, and finally enters the buffer for separation again.

[0029] refer to Figure 4 The cleaning structure 9 includes a connecting block 10 fixedly connected to the bottom of the supporting plate 3. The interior of the connecting block 10 is movably connected to a shaft 11 through a bearing. The front end of the shaft 11 passes through the box body 1 and extends to the back of the box body 1. The surface of the shaft 11 is fixedly connected to a pressure plate 12. The side of the pressure plate 12 away from the shaft 11 passes through the supporting plate 3 and contacts the surface of the absorption block 4. The shaft 11 can drive the pressure plate 12 to swing and press out the separation liquid inside the absorption block 4 when squeezing the absorption block 4.

[0030] As a technical optimization solution of the present invention, the introduction of the cleaning structure 9 solves the problem that the absorption block 4 is full of water and easy to be blocked after long-term use. The pressure plate 12 is driven to swing by the shaft 11. The pressure plate 12 can press out the separation liquid accumulated inside the absorption block 4 when squeezing it, and discharge it through the drain pipe 8, thereby realizing the self-cleaning and regeneration of the absorption block 4, extending the service life of the absorption block 4, and also ensuring the continuous and efficient separation ability of the device.

[0031] refer to Figure 4 The shaft 11 extends through one end of the box body 1 and is fixedly connected to a rocker arm 13 . A sleeve plate 14 is provided on the front of the box body 1 . Both sides of the sleeve plate 14 can contact the end of the rocker arm 13 away from the shaft 11 .

[0032] As a technical optimization solution of the present invention, the design of the rocker arm 13 and the sleeve plate 14 enables external power to indirectly act on the shaft 11, thereby driving the pressure plate 12 to swing and clean, simplifying the transmission structure, reducing maintenance costs, and improving the stability and reliability of the system.

[0033] refer to Figure 3 The front of the box body 1 is fixedly connected to a bracket 15, and the front of the bracket 15 is fixedly connected to a transmission motor 16.

This linkage utilizes the spatial layout of the device itself and realizes multiple utilization of power.

[0035] refer to Figure 4 The front of the box body 1 is fixedly connected with a guide rod 20 , and the sleeve plate 14 is sleeved on the surface of the guide rod 20 and is slidably connected with the guide rod 20 .

[0036] As a technical optimization solution of the present invention, the guide rod 20 provides stable support and guidance for the movement of the sleeve 14, avoiding the sleeve 14 from offsetting or shaking during the movement, which helps to improve the accuracy and reliability of the cleaning structure 9, and also protects other related components from unnecessary wear and damage.

[0037] refer to Figure 4One end of the rocker arm 13 away from the shaft 11 is fixedly connected to a roller 21 , and the outer surface of the roller 21 can contact the surface of the sleeve plate 14 .

[0038] As a technical optimization solution of the present invention, the design of the roller 21 reduces direct friction between the rocker 13 and the sleeve 14, reduces movement resistance and wear, and extends the service life of related components.

[0039] The working principle and use process of the utility model are as follows: the transmission motor 16 drives the guide fan 7 to operate and pressurize the shale gas. The shale gas is introduced into the device through the air pipes 6 connected to the two sides of the box body 1. These air pipes 6 are closely connected to the box body 1 to ensure that the air flow can enter smoothly. After entering the box body 1, the air flow first encounters the absorption blocks 4 arranged on both sides of the top of the supporting plate 3. These absorption blocks 4 are elastic and guide the air flow through the microporous interface. At the same time, they can absorb moisture in the air flow. This step realizes the preliminary filtration of the air flow and the removal of moisture. The air flow processed by the absorption block 4 passes through the two absorption blocks 4. The absorption block 4 is discharged through the air pipe 6 on the other side. During the operation of the transmission motor 16, the transmission motor 16 can drive the pulley 17 connected to its output end to rotate. Through the transmission of the belt 18 and the other pulley 17, the slide bar 19 on the front pulley 17 of the box body 1 slides in the sleeve 14, thereby driving the sleeve 14 to move left and right. The movement of the sleeve 14 drives the rocker arms 13 on both sides to swing intermittently, and the rocker arms 13 drive the pressure plate 12 to swing under the supporting plate 3 through the shaft 11. The pressure plate 12 squeezes the absorption block 4 during the swinging process, squeezes out the water absorbed inside the absorption block 4, and discharges it from the box body 1 through the drain pipe 8.

[0040] To sum up: the gas-liquid separation device developed based on shale gas, by setting up an internal filtering structure 2, including a supporting plate 3, an absorption block 4 and a diversion plate 5, can effectively separate shale gas from liquid. The absorption block 4 uses its elasticity and microporous interface design to not only guide the airflow, but also absorb moisture in the airflow, thereby improving the separation efficiency. At the same time, the bottom of the supporting plate 3 extends into the separation liquid to avoid gas overflow, making the separation process more thorough.
