DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] The present application provides a kind of slug flow trap's gas-liquid separation mechanism, as shown in Figures 1-4 Figure 1, including trap body 1, the outside of one side of trap body 1 is provided with gas-liquid separation tank 2, one side of gas-liquid separation tank 2 is connected with feed pipe 3, the upper part of the other side of gas-liquid separation tank 2 is connected with gas outlet pipe 4, the outer end of gas outlet pipe 4 is connected with the upper part of trap body 1, the lower part of the other side of gas-liquid separation tank 2 is connected with liquid outlet pipe 5, the outer end of liquid outlet pipe 5 is connected with the lower part of trap body 1. Through the structure layout of careful design, efficient and orderly gas-liquid separation process is realized. Specifically, the ingenious combination of trap body 1 and gas-liquid separation tank 2 enables mixed gas and liquid to smoothly enter the separation system through feed pipe 3. Inside gas-liquid separation tank 2, gas and liquid are effectively separated under specific flow paths: the gas part is guided to the upper part of trap body 1 through gas outlet pipe 4, while the liquid part flows out to the lower part of trap body 1 through liquid outlet pipe 5.

[0024] Such design not only ensures the complete separation of gas-liquid two-phase, avoids the problem of liquid carrying gas or gas mixed with liquid commonly seen in traditional equipment, but also significantly improves the separation efficiency. At the same time, the structure of the mechanism is compact and reasonable, easy to install and maintain, providing an efficient and reliable solution for the gas-liquid separation needs of petroleum, natural gas and chemical industries.

[0025] In this embodiment, a center pipe 24 is installed in the middle of the interior of the gas-liquid separation tank 2, the outer wall of the center pipe 24 is installed with spiral vanes 242, and the bottom end of the center pipe 24 is provided with an air inlet 243. The center pipe 24 installed in the middle of the interior of the gas-liquid separation tank 2 and the spiral vanes 242 on the outer wall thereof together constitute a high-efficiency gas-liquid preliminary separation structure. The design of the spiral vanes 242 causes the mixed fluid entering the gas-liquid separation tank 2 to generate rotational flow when flowing through the center pipe 24, which helps to increase the gas-liquid contact area and promote the separation of gas from the liquid, and the gas enters the interior of the center pipe through the air inlet 243 at the bottom end of the center pipe, which provides convenience for subsequent gas collection and discharge.

[0026] Specifically, a baffle 241 is installed on the top outside of the center pipe 24. This effectively prevents the gas escaping from the top of the center pipe from directly impacting the top wall of the gas-liquid separation tank 2, reduces the turbulence and backflow of the gas, ensures that the gas can rise smoothly and be discharged through the gas outlet 22, and further improves the separation efficiency and purity of the gas.

[0027] Further, the gas-liquid separation tank 2 is provided with a feed inlet 21 on the side close to the feed pipe 3, the feed inlet 21 is connected with the feed pipe 3, the gas-liquid separation tank 2 is provided with a gas outlet 22 on the side close to the gas outlet pipe 4, the gas outlet 22 is connected with the gas outlet pipe 4, and the gas-liquid separation tank 2 is provided with a liquid outlet 23 close to the liquid outlet pipe 5, the liquid outlet 23 is connected with the liquid outlet pipe 5. The above-mentioned arrangement forms a clear and orderly fluid channel. This design not only facilitates the entry of mixed fluid and the separate discharge of gas-liquid two-phase after separation, but also reduces the residence and mixing of fluid in the tank, thereby improving the separation efficiency.

[0028] Further, the top end of the center pipe 24 is connected with a flow regulator 25, and the top end of the flow regulator 25 is connected with the gas outlet 22.

[0029] Further, a blocking mechanism 26 is installed at the bottom of the gas-liquid separation tank 2 close to the liquid outlet 23, the blocking mechanism 26 includes a support column 261, and the top of the support column 261 is installed with a blocking plate 262. This effectively prevents the backflow and vortex of the liquid, ensures that the liquid can flow out smoothly and stably from the liquid outlet 23, reduces the carried gas and impurities of the liquid, and improves the purity of the liquid.

[0030] Further, the two ends of the blocking plate 262 are inclined downward. This facilitates the downward sliding of the liquid.

[0031] Further, a bottom of the gas-liquid separation tank 2 is provided with a foreign matter removal bin 6 near the liquid outlet pipe 5, an inner portion of the foreign matter removal bin 6 is provided with an inclinedly arranged filter screen 61, a top end of the foreign matter removal bin 6 is connected with the liquid outlet 23, one side of the foreign matter removal bin 6 is connected with the liquid outlet pipe 5, and the other side of the foreign matter removal bin 6 is provided with a cleaning opening 62, and a detachable sealing cover is arranged outside the cleaning opening 62. The foreign matter removal bin 6 facilitates the last removal of foreign matters and filtration of the liquid flowing out of the liquid outlet 23. The filter screen 61 can effectively remove the tiny impurities and bubbles in the liquid, thereby improving the purity of the liquid. Meanwhile, the cleaning opening 62 arranged on one side of the foreign matter removal bin 6 and the detachable sealing cover facilitate the cleaning and replacement of the filter screen 61, thereby ensuring the continuous and efficient operation of the device.

[0032] The gas-liquid separation mechanism of the plug flow trap in the utility model is used, first, the mixed gas and liquid enter the gas-liquid separation tank 2 through the feed pipe 3. The feed pipe 3 is connected with the feed inlet 21 on the gas-liquid separation tank 2, which ensures that the mixed fluid can smoothly enter the separation system.

[0033] The mixed fluid entering the gas-liquid separation tank 2 generates rotary flow under the guidance of the spiral flow guide vane 242 when flowing through the center pipe 24. The rotary flow increases the gas-liquid contact area and promotes the separation of gas from the liquid. The separated gas enters the inside of the center pipe through the gas inlet 243 at the bottom end of the center pipe 24, while the liquid continues to flow in the outside space of the gas-liquid separation tank 2.

[0034] The gas entering the center pipe 24 is blocked by the baffle 241 during the rising process, which reduces the turbulence and backflow phenomenon of the gas. The gas then passes through the flow regulator 25 for flow regulation and stabilization, ensuring that it is discharged from the gas outlet 22 in a smooth state, enters the gas outlet pipe 4, and is finally guided to the upper part of the trap body 1.

[0035] At the bottom of the gas-liquid separation tank 2, the separated liquid flows out through the liquid outlet 23. In this process, the blocking mechanism 26 (including the support column 261 and the blocking plate 262) effectively prevents the backflow and vortex phenomenon of the liquid, ensuring the stable and smooth flow of the liquid. The liquid then enters the foreign matter removal bin 6 and is subjected to the last removal of foreign matters and filtration through the inclinedly arranged filter screen 61, thereby removing tiny impurities and bubbles. The filtered pure liquid flows out through the liquid outlet pipe 5 to the lower part of the trap body 1.

[0036] The cleaning opening 62 arranged on one side of the foreign matter removal bin 6 and the detachable sealing cover facilitate the regular cleaning and replacement of the filter screen 61. This design ensures the continuous and efficient operation of the device and the purity of the liquid.

[0037] Finally, it needs to be explained that the trap body 1 in the embodiment, etc., the electronic components in the above components are all general standard components or components known to those skilled in the art, the structure and principle are known to those skilled in the art through technical manual or through conventional experimental method, all the above electric appliances are connected through the wire respectively in the idle place of the device, the specific connection means should be referred to the working order between the electric appliances in the above working principle to complete the electrical connection, which are all the known technology in the art.
