Description

Technical Field

[0002] In the process of natural gas extraction and transportation, the efficient separation of solid impurities such as sand particles is a key link to ensure the safe operation of pipeline equipment.

[0003] Although existing natural gas cyclone sand separators can achieve gas-solid separation through centrifugal force, they still have obvious shortcomings in practical applications: on the one hand, traditional sand collection tanks require frequent shutdowns for cleaning, resulting in high maintenance costs and affecting the continuous operation of the equipment; on the other hand, cleaning the deposited sand particles mostly relies on manual operation or complex mechanical structures, with low automation and limited sand cleaning efficiency. In addition, the wear-resistant lining inside the shell is mostly an integral design, which is difficult and costly to replace after wear.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] Please refer to the following: Figure 1-9 ,in, Figure 1 This is a three-dimensional structural diagram of a high-efficiency cyclone sand separator for natural gas proposed in this utility model; Figure 2 for Figure 1 A schematic diagram of the cross-sectional structure; Figure 3 for Figure 2 A structural diagram from a frontal viewpoint; Figure 4 This is a partial three-dimensional structural schematic diagram of the present invention; Figure 5 for Figure 2 Enlarged view of section A; Figure 6 This is a schematic diagram of the structure of the shell, the second locking block, and the air intake pipe proposed in this utility model; Figure 7 This is a structural schematic diagram of a portion of the top cover, lifting lug, annular groove, sealing ring, and locking block proposed in this utility model. Figure 8 This is an exploded view of the wear-resistant liner proposed in this utility model; Figure 9 This is a schematic diagram of the sand removal component proposed in this utility model. A high-efficiency natural gas cyclone sand separator includes: a shell 1, a top cover 11, an air inlet pipe 101, an overflow pipe 111, a wear-resistant liner 2, a sand collection tank 3, and a support frame;

[0032] The support frame is fixedly installed on the housing 1. The air intake pipe 101 is fixedly installed on the housing 1 and extends into the housing 1 along the tangent direction of the housing 1. The wear-resistant liner 2 is snapped into the housing 1, and the wear-resistant liner 2 has through holes adapted to the air intake pipe 101. The top cover 11 is detachably and sealed on the top of the housing 1. Multiple U-shaped locking blocks 12 are fixedly installed on the top cover 11. Multiple locking blocks 2 13 are fixedly installed on the outer top of the housing 1. The multiple locking blocks 12 are respectively snapped into the corresponding locking blocks 2 13, which facilitates quick connection and fixation of the top cover 11 and the housing 1, and also facilitates the disassembly of the top cover 11.

[0033] The overflow pipe 111 is fixedly installed on the top cover 11 at the center position. The sand collection tank 3 is fixedly installed on the bottom of the shell 1 and kept in a connected state. The bottom of the sand collection tank 3 is fixedly installed with a storage tank 31. The bottom of the storage tank 31 is fixedly installed with a discharge pipe equipped with a control valve at the center position. Multiple connecting pipes 32 are fixedly installed on the sand collection tank 3. All multiple connecting pipes 32 are connected to the storage tank 31, which can transfer the sand particles in the sand collection tank 3 to the storage tank for storage, reducing the frequency of maintenance.

[0034] A support strip 401 is installed inside the inlet of the sand collection tank 3. A rotating shaft 4 is rotatably installed on the support strip 401. The bottom end of the rotating shaft 4 extends into the sand collection tank 3 and is fixedly installed with multiple baffles 42. When the rotating shaft 4 rotates, the multiple baffles 42 can be controlled to blow sand particles toward the position of the connecting pipe 32. The top end of the rotating shaft 4 extends into the housing 1 and is fixedly installed with multiple inclined baffles 41. Under the influence of the airflow movement in the housing 1, the rotating shaft 4 can be driven by the airflow movement.

[0035] In this method, in order to ensure the stable rotation of the shaft 4 and to enable the quick disassembly of the shaft 4 after removing the wear-resistant liner 2, a support ring is fixedly installed inside the inlet of the sand collection tank 3. The support ring has two slots, and the support strip 401 is snapped into the two slots, with the top side of the support strip 401 abutting against the bottom side of the wear-resistant liner 2.

[0036] In this method, in order to facilitate the disassembly and assembly of the top cover 11 using hoisting equipment, multiple lifting lugs are fixedly installed on the top cover 11.

[0037] In this method, in order to ensure the sealing of the connection between the top cover 11 and the housing 1, annular grooves are provided on the sides of the top cover 11 and the housing 1 that are close to each other, and sealing rings are fixedly installed on the sides of the top cover 11 and the housing 1 that are close to each other. The two sealing rings are respectively movably sealed in the corresponding annular grooves.

[0038] In this method, in order to facilitate individual replacement and prevent sand particles from entering the connection of the wear-resistant liner 2, the wear-resistant liner 2 is set in a split manner and maintains a snap-fit ​​connection, and the connection near the axis of the shell 1 is set downward.

[0039] In this method, in order to reduce the accumulation of sand particles and facilitate the transfer of sand particles, the bottom inner wall of the sand collection tank 3 is set in a state where the middle is high and the surrounding area is low, and the bottom inner wall of the storage tank 31 is set in a state where the surrounding area is high and the middle is low.

[0040] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0041] The working principle of the high-efficiency cyclone sand separator for natural gas provided by this utility model is as follows:

[0042] After natural gas enters the casing 1 through the inlet pipe 101, it forms a high-speed swirling flow under the guidance of the tangential direction. During the swirling motion, due to the centrifugal force, sand particles are thrown towards the inner wall of the casing 1 and settle into the sand collection tank 3 under the action of gravity. The wear-resistant liner 2 effectively reduces the wear of sand particles on the inner wall of the casing 1 and extends the service life of the equipment. When the airflow generated in the casing 1 of the natural gas machine causes multiple baffles 41 to drive the rotating shaft 4 to rotate, which in turn drives multiple baffles 42 to push the sand particles gathered in the sand collection tank 3 towards the connecting pipe 32. Under the action of multiple connecting pipes 32, the sand particles are guided to the storage tank 31. When the sand particles in the storage tank 31 accumulate to a certain extent, the discharge pipe can be opened by the control valve to discharge them, thereby achieving the effect of cleaning without frequent shutdowns.

[0043] The sealing design between the top cover 11 and the housing 1 ensures that no gas leakage will occur during equipment operation. The interlocking connection of multiple locking blocks 12 and multiple locking blocks 13 makes the disassembly and installation of the top cover 11 more convenient, facilitating the maintenance or replacement of internal components. In addition, the design of the split wear-resistant inner liner 2 allows for the replacement of only the parts that need to be replaced according to actual needs, without the need to replace the entire unit, effectively reducing replacement costs and further improving the overall performance and reliability of the equipment.
