Description

Technical Field

[0001] This utility model relates to the field of gas purification technology, specifically to a spiral separator. Background Technology

[0002] In gas engineering, separators are widely used. They can be used to separate and purify various gases such as natural gas, liquefied petroleum gas, and coal gas to ensure gas quality and stability. Separators can also be used in various equipment such as gas-fired power generation, gas-fired heating, and gas furnaces to ensure the normal operation and safety of the equipment.

[0003] Separators are crucial equipment in gas engineering, primarily functioning to separate liquid and solid impurities from a gas mixture, ensuring the purity and stability of the gas. During gas transmission, liquid and solid impurities can affect the flowability and calorific value of the gas, and may even damage equipment. Therefore, separators are indispensable in gas engineering.

[0004] The principle of a separator is based on centrifugal force and gravity separation. It utilizes the internal structure of the separator and the fluid's motion to separate liquid and solid impurities from a gas. Separators typically contain filters and partitions to enhance separation efficiency. Inside the separator, gas enters from one port, passes through the filters and separator, and the purified gas flows out from the other port, while impurities are collected in a collector inside the separator.

[0005] Most gas separators on the market currently use a method of directly redirecting the airflow channel for gas separation. This mainly involves welding elbows and bends inside the separator. At the bends, the gas changes direction sharply. During this process, because the inertia of gases and solids is greater than that of liquids, the liquid and solid impurities in the gas are separated. A relatively large airflow is generally required to achieve gas separation. Under high airflow conditions, the impact of the gas can easily cause uneven stress on the welded elbows or bends, and moisture can easily accumulate at the inside corners of the elbows. Over time, this can lead to breakage at the welded joints. However, since the gas flow channels inside the separator are welded together, if problems such as breakage, loosening, or abnormal noise occur at some welded points after welding, the entire device needs to be disassembled and opened to replace and maintain the gas flow. This disassembly is very difficult and increases maintenance costs.

[0006] In view of the above, this utility model is hereby proposed. Utility Model Content

[0047] Example 1

[0048] See Figures 1 to 4 As shown, this embodiment provides a spiral separator, including a cylinder 1 and a separator core assembly 2. The cylinder 1 has a cavity 11, a mounting port 12, and an air inlet 13, both of which communicate with the cavity 11. The separator core assembly 2 can be inserted into or removed from the cavity 11 through the mounting port 12. The separator core assembly 2 is detachably connected to the cylinder 1, and has a through exhaust channel 201. When the separator core assembly 2 is installed in the cylinder 1, it covers the mounting port 12, forming a separation channel between the separator core assembly 2 and the inner wall of the cylinder 1. The air inlet 13 communicates with the separation channel, and the exhaust channel 201 communicates with the cavity 11. Damage to spiral separators is often caused by long-term impact of airflow or corrosion from liquids on the separator core assembly 2. The spiral separator of this patent application has a detachable connection between the separator core assembly 2 and the cylinder body 1. If the separator core assembly is damaged, the separator core assembly 2 can be directly removed from the cylinder body 1, so that the separator core assembly 2 can be replaced, repaired or maintained. This makes the replacement, repair and maintenance of the separator core assembly 2 very convenient and greatly reduces the cost of spiral separator repair and maintenance.

[0049] During installation, the spiral separator of this patent application is inserted into the cavity 11 through the mounting port 12. The air inlet 13 of the exhaust channel 201 of the spiral separator 2 is located inside the cavity 11, and the air outlet of the exhaust channel 201 is located outside the cylinder body 1. The spiral separator 2 is detachably connected to the cylinder body 1. When the spiral separator is in use, gas enters the separation channel between the spiral separator 2 and the cylinder body 1 through the air inlet 13, separating liquid and solid impurities from the gas. The liquid and solid impurities flow along the side wall of the cylinder body 1 to the bottom of the cylinder body 1, while clean gas enters through the air inlet 13 of the exhaust channel 201 and is discharged outside the cylinder body 1 through the air outlet of the exhaust pipe.

[0050] In some possible implementations, the separator core assembly 2 includes a mounting portion 22, a separating portion 23, and an air collecting portion 21. The separating portion 23 is located between the mounting portion 22 and the air collecting portion 21, and the exhaust passage 201 passes through the mounting portion 22, the separating portion 23, and the air collecting portion 21. With the separator core assembly 2 installed on the cylinder body 1, the air collecting portion 21 and the separating portion 23 are located within the cavity 11. The mounting portion 22 is connected to the cylinder body 1 and covers the mounting port 12. The separating passage is formed between the separating portion 23 and the inner wall of the cylinder body 1. The air inlet 13 of the exhaust passage 201 is located on the air collecting portion 21, and the air outlet of the exhaust passage 201 is located on the mounting portion 22. When the spiral separator is in use, the gas enters the separation channel between the separation section 23 and the cylinder 1 through the air inlet 13. The separation section 23 separates the liquid and solid impurities in the gas. The liquid and solid impurities flow along the side wall of the cylinder 1 to the bottom of the cylinder 1. The clean gas enters the exhaust channel 201 through the gas collection section 21 and is discharged from the cylinder 1 through the exhaust port of the exhaust pipe via the exhaust channel 201.

[0051] In some possible implementations, the inner wall of the mounting port 12 of the cylinder body 1 is provided with internal threads, and the mounting part 22 has external threads 2211. When the separator core assembly 2 is installed on the cylinder body 1, the mounting part 22 is threadedly connected to the internal threads. The separator core assembly 2 and the cylinder body 1 are connected by threads, and the separator core assembly 2 can be disassembled and installed by screwing, making it convenient to remove and install the separator core assembly 2 from the cylinder body 1 without requiring professional technicians, further reducing the cost of maintenance and upkeep of the spiral separator.

[0052] In some possible implementations, the mounting portion 22 includes an inner body 221, an outer body 222, and a cap 223 located between the inner body 221 and the outer body 222, wherein the outer diameter of the cap 223 is larger than that of the inner body 221. The inner body 221 has the external thread 2211. When the separator core assembly 2 is installed on the cylinder 1, the inner body 221 is threadedly connected to the internal thread. The cap 223 is confined to the surface of the cylinder 1 and covers the mounting opening 12. The inner body 221 extends into the cavity 11 of the cylinder 1 and is threadedly connected to the cylinder 1. The cap 223 serves as a limit to prevent the mounting portion 22 from extending excessively into the cavity 11. The cap 223 can completely cover the mounting opening 12 to prevent foreign objects from entering between the internal thread and the external thread 2211, ensuring connection stability and preventing foreign objects from affecting the disassembly and assembly of the separator core assembly 2.

[0053] In some possible implementations, the outer diameter of the gas collecting section 21 is not greater than the outer diameter of the inner body 221. Thus, after the inner body 221 is separated from the cylinder 1 by screwing, the gas collecting section 21, along with the mounting section 22 and the separation section 23, can also be removed through the mounting port 12. This makes it easy to maintain the gas collecting section 21 when maintenance is needed, further reducing the cost of maintenance and upkeep of the spiral separator.

[0054] In some possible implementations, of the mounting part 22, the separating part 23, and the gas collecting part 21, at least the mounting part 22 and the separating part 23 are integrally formed. An integrally formed structure has high stability, is not easily damaged, and is less likely to produce abnormal noise during operation. Preferably, at least the mounting part 22 and the separating part 23 are forged from 45 steel, capable of withstanding high pressures of 10-50 MPa.

[0055] In some possible implementations, the cavity 11 includes a coarse-diameter cavity 111 and a fine-diameter cavity 112, which are connected. The mounting port 12 is connected to the fine-diameter cavity 112, and the air inlet 13 is also connected to the fine-diameter cavity 112. With the separator core assembly 2 installed in the cylinder 1, the gas collecting section 21 is located in the coarse-diameter cavity 111, and the separating section 23 is located in the fine-diameter cavity 112, forming a separation channel between the separating section 23 and the fine-diameter cavity 112. Setting the smaller diameter fine-diameter cavity 112 and placing the separation channel within it reduces the path width of the separation channel, increases the airflow velocity, and ensures effective separation. Setting the larger diameter coarse-diameter cavity 111 can accommodate the separated impurities (liquid and solid) and reduces the flow velocity of gas entering the gas collecting section 21, decreasing the probability of the cleaned gas re-entraining liquid.

[0056] In some possible implementations, the outer wall of the separation section 23 is provided with spiral ribs 231. The spiral ribs 231 form a spiral shape in the separation channel. After the gas is introduced from the air inlet 13, it enters the spiral separation channel and rotates at high speed to separate. The spiral separation channel can extend the length of the separation channel and is constantly changing its direction of operation. During the high-speed rotation of the gas, the centrifugal force causes liquid water and solid matter to peel off and accumulate on the surrounding walls, resulting in a good separation effect.

[0057] In some possible implementations, the gap between the spiral rib 231 and the inner wall of the narrow-diameter cavity 112 is less than 1 mm. Extensive experiments have shown that this size of gas channel provides the best gas separation performance.

[0058] In some possible implementations, the cylinder body 1 includes a top cylinder body 1011, a middle cylinder body 1021, and a bottom cylinder body 1031. The middle cylinder body 1021 has an upper opening and a lower opening. The bottom cylinder body 1031 is connected to the middle cylinder body 1021 and closes the lower opening. The top cylinder body 1011 is connected to the middle cylinder body 1021 and covers the upper opening. The top cylinder body 1011 has the mounting port 12 and the air inlet 13. The top cylinder body 1011 and the separator core assembly 2 are detachably connected. The coarse-diameter cavity is located within the middle cylinder body 1021, the fine-diameter cavity is located within the top cylinder body 1011, and the internal thread is located within the top cylinder body 1011. The top cylinder body 1011 and the bottom cylinder body 1031 are welded to the middle cylinder body 1021, facilitating the separate production of each component and reducing production costs.

[0059] The preferred embodiments disclosed above are merely illustrative of this application. These preferred embodiments do not exhaustively describe all details, nor do they limit the application to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this application, thereby enabling those skilled in the art to better understand and utilize this application. This application is limited only by the claims and their full scope and equivalents.
