Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas separation technology, and in particular to an energy-saving gas separation device. Background Technology
[0002] According to the Chinese Publication (Announcement) No. CN115069028A, a reliable centrifugal gas-liquid separator includes: an inner tube (2) and a spiral assembly (3). The inner tube (2) is a cylindrical body that extends vertically and has a separation chamber (22) inside. A first air inlet (21) is provided on its side wall. The spiral assembly (3) includes a top baffle (31), a riser pipe (32) and a spiral plate (33). The top baffle (31) is fixedly connected to the upper opening of the inner tube (2) and has a first air outlet (35). The riser pipe (32) is a slender tubular structure that extends along the separation chamber (22). It is fixedly connected to the top baffle (31) and passes through the first air outlet (35). The spiral plate (33) spirals downward around the riser pipe (32) and is connected to the inner wall of the inner tube (2) to form a guide channel (34) for the flow of the mixed fluid to be separated.
[0003] Existing centrifugal gas-liquid separators have certain limitations. Firstly, during long-term operation, internal components are susceptible to contamination, corrosion, and mechanical wear from impurities in the gas-liquid mixture. Secondly, the internal structure of many centrifugal gas-liquid separators is not conducive to quick and convenient disassembly and maintenance. Once components are damaged or their performance degrades, repairs are time-consuming, affecting production continuity and increasing downtime costs. Furthermore, the fixed spacing of the spiral blades in existing centrifugal gas-liquid separators makes it difficult to flexibly adjust according to actual operating conditions. When operating conditions change, the fixed-spacing spiral blades may fail to provide optimal centrifugal separation, leading to reduced separation efficiency, incomplete gas-liquid separation, and consequently affecting the stability of subsequent processes and product quality. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to quickly disassemble the internal structure of the liquid separator and the inability to change the spacing of the spiral blades, and to propose an energy-saving gas separation device.

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:
[0025] Reference Figure 1-6An energy-saving gas separation device includes a separator body 1, a top cover 2 on the top of the separator body 1, a liquid inlet 3 on the top surface of the separator body 1, an exhaust port 4 on the side of the separator body 1 away from the liquid inlet 3, a drain port 5 on the bottom surface of the separator body 1, an exhaust pipe 6 on the bottom surface of the top cover 2, an inner tube 7 on the top surface of the exhaust pipe 6, a return spring 10 on the outside of the inner tube 7, an outer tube 8 on the outside of the return spring 10, a moving tube 9 on the side of the return spring 10 away from the exhaust pipe 6, a connecting frame 11 on the bottom surface of the exhaust pipe 6, a liquid separating plate 14 at the bottom of the connecting frame 11, a connecting pipe 12 on the outside of the exhaust pipe 6, and spiral blades 13 on the outer surface of the connecting pipe 12. The exhaust port 4 is mirror-image of the separator body 1, and the liquid inlet 3, liquid outlet 5, and exhaust port 4 are all integrally formed with the separator body 1. The top cover 2 is integrally formed with the separator body 1, and the top cover 2 is integrally formed with the exhaust pipe 6. The inner pipe 7 and the outer pipe 8 are aligned with the horizontal central axis of the exhaust pipe 6, and the inner pipe 7 and the outer pipe 8 are integrally formed with the exhaust pipe 6. The moving pipe 9 is located in the middle of the inner pipe 7 and the outer pipe 8. The moving pipe 9 is sleeved with the inner pipe 7, and one end of the moving pipe 9 passes through the interior of the exhaust port 4. The spiral blade 13 is welded to the connecting pipe 12, and the connecting pipe 12 is threadedly connected to the exhaust pipe 6. The connecting frame 11 is welded to the exhaust pipe 6. The liquid distribution plate 14 is located inside the separator body 1, and the liquid distribution plate 14 is bolted to the connecting frame 11.
[0026] The separator body 1 serves as the basic container for gas-liquid separation, providing a containment space. Its inner wall mates with the spiral blades 13, guiding the gas-liquid mixture to form a spiral motion path, creating conditions for the separation process. The top cover 2 seals the top of the separator body 1 and is integrally formed with the exhaust pipe 6. During disassembly and installation, it facilitates the movement of the exhaust pipe 6 and related components, making maintenance and replacement of the internal structure easier. The liquid inlet 3 is the entrance for the gas-liquid mixture into the separator body 1, defining its entry position and direction, allowing it to smoothly enter the separation space. The exhaust port 4 is the channel for the separated gas to exit, mates with the moving pipe 9, allowing the gas to smoothly exit the separator body 1. The liquid outlet 5 is the outlet for the separated liquid. Under the action of gravity and centrifugal force, the separated liquid flows down the inner wall of the separator body 1 to the bottom of the separating plate 14 and exits through the liquid outlet 5. The exhaust pipe 6 guides the separated gas upwards and is the main channel for gas discharge. It is integrally formed with the top cover 2 and threadedly connected to the connecting pipe 12, facilitating overall disassembly and replacement of the connecting pipe 12 during maintenance. The inner tube 7 is located at the top of the exhaust pipe 6, serving two purposes: transporting gas and guiding the return spring 10 and the moving tube 9, ensuring the moving tube 9 maintains the correct position and orientation during extension and retraction. The outer tube 8 is integrally formed with the exhaust pipe 6, providing space for the moving tube 9 to extend and retract. During installation, it works with the moving tube 9 and the return spring 10 to connect with the exhaust port 4. The moving tube 9 is sleeved on the inner tube 7 and can move between the inner tube 7 and the outer tube 8. During installation, it is compressed into the outer tube 8 by the inner wall of the separator body 1; after installation, it extends and inserts into the exhaust port 4 under the action of the return spring 10, forming a channel for gas discharge. The return spring 10 is installed inside the outer tube 8, with one end connected to the inner tube 7 and the other end connected to the moving tube 9. It is compressed during installation and releases its elasticity after installation, pushing the moving tube 9 to align with the exhaust port 4, ensuring the continuity of the gas channel. The connecting bracket 11 is welded to the bottom of the exhaust pipe 6 to support and fix the liquid separator plate 14, keeping it in a suitable position within the separator body 1 to assist in the gas-liquid separation process. The connecting pipe 12 is threaded to the exhaust pipe 6, and its outer surface is welded with spiral blades 13. Depending on different operating conditions, the connecting pipe 12 with spiral blades 13 at different spacings can be replaced by rotating it to separate or connect to the exhaust pipe 6, thus adjusting the gas-liquid separation conditions. The spiral blades 13 are welded to the connecting pipe 12. After the gas-liquid mixture enters the separator body 1, it rotates downwards along the spiral channel formed by the pipe and the inner wall of the separator body 1. Centrifugal force, combined with gravity, causes the heavier liquid to move towards the inner wall of the spiral channel and accumulate, achieving initial gas-liquid separation. Spiral blades 13 with different spacings can adapt to different properties of gas-liquid mixtures and separation requirements. The separating plate 14 is connected to the connecting frame 11 by bolts and is located inside the separator body 1. When the gas-liquid mixture reaches this point, further gas-liquid separation occurs, causing the liquid to descend along the inner wall of the separator body 1 to the drain port 5 for discharge, while the gas continues to rise along the exhaust pipe 6. Specific Implementation Example 2:
[0028] Reference Figure 1-6 An energy-saving gas separation device is further based on the basic structure in Specific Embodiment 1. The specific workflow is as follows: the gas-liquid mixture enters the separator body 1 through the inlet 3 and rotates downwards along the spiral channel formed by the inner wall of the separator body 1 and the spiral blades 13. During rotation, due to the higher specific gravity of the liquid, under the combined action of gravity and centrifugal force, the liquid gradually moves towards the inner wall of the spiral channel and accumulates. When the gas-liquid mixture reaches the separating plate 14, the gas and liquid are further separated. The liquid flows down along the inner wall of the separator body 1 to the bottom of the separating plate 14 and is then discharged from the device through the drain port 5. The gas, on the other hand, rises along the exhaust pipe 6, first passing through the inner pipe 7, then entering the moving pipe 9, and then through the moving pipe 9 into the exhaust pipe 6, finally being discharged from the exhaust port 4. For equipment maintenance, the exhaust pipe 6 is integrally formed with the top cover 2, and the connecting pipe 12 is threadedly connected to the exhaust pipe 6. When the fixing bolts of the top cover 2 are removed and the top cover 2 is pulled upwards, the exhaust pipe 6 and the connecting pipe 12 will be pulled out together. Then rotate the connecting pipe 12 to separate it from the exhaust pipe 6. Replace the connecting pipe 12 with a spiral blade 13 of different spacing according to the actual working conditions. After replacement, reverse the operation to install. During the installation process, the moving pipe 9 is squeezed into the outer pipe 8 by the inner wall of the separator body 1. When the outer pipe 8 of the exhaust pipe 6 moves to the exhaust port 4, the return spring 10 pushes the moving pipe 9 into the exhaust port 4. Finally, fix the top cover 2 to realize the quick disassembly of the internal structure of the separator body 1 and the replacement of the spiral blade 13 spacing to meet the gas-liquid separation requirements under different working conditions.
[0029] In summary:
[0030] 1. The exhaust pipe 6 is welded to the top cover 2, and the connecting pipe 12 is threaded to the exhaust pipe 6. When the fixing bolts of the top cover 2 are removed and the top cover 2 is pulled upwards, the exhaust pipe 6 and the connecting pipe 12 will be pulled out together. After being pulled out, the exhaust pipe 6 and the connecting pipe 12 will be taken out of the separator body 1. After being taken out, the connecting pipe 12 is rotated to separate the connecting pipe 12 from the exhaust pipe 6. After separation, the connecting pipe 12 with different pitch spiral blades 13 can be replaced according to the required working conditions. After replacement, the connecting pipe 12 is rotated to connect the connecting pipe 12 to the exhaust pipe 6 through threads. After connection, the connecting pipe 12 and the exhaust pipe 6 are installed into the interior of the separator body 1, and the top cover 2 is installed on the separator body 1 with fixing bolts. This completes the quick disassembly of the internal structure of the separator body 1 and the replacement of different pitches of spiral blades 13, solving the shortcomings of the inability to quickly disassemble the internal structure of the separator body 1 and the inability to change the pitch of spiral blades 13.
