Description

Technical Field

[0001] This utility model relates to the technical field of natural gas blending and gathering equipment, specifically to a high-efficiency blending processor for natural gas gathering and transportation. Background Technology

[0002] Natural gas, as a clean energy source, is widely used in daily production and life, and plays a crucial role in the national economy. In recent years, the increasing demand for natural gas has led to a prominent supply-demand imbalance. The natural gas used in the gas fields and reservoirs explored and developed in recent years has contained hydrogen sulfide, and the hydrogen sulfide content varies significantly depending on the strata of the developed gas fields and reservoirs. Due to insufficient sulfur resistance in the initially designed pipelines transporting sulfur-containing natural gas, and a severe shortage of downstream natural gas purification plants capable of processing high-sulfur-content natural gas, while purification plants processing low-sulfur-content natural gas have significant overcapacity, maximizing the efficiency and effectiveness of existing equipment and facilities through scientific and technological innovation to ensure supply has become a critical issue concerning national welfare, people's livelihood, and social harmony and stability.

[0003] To address these issues, the current approach involves process modification and flow reversal, blending high-sulfur feedstock gas with low-sulfur natural gas or with purified product-grade natural gas to reduce the sulfur content of the feedstock gas, meeting the design requirements for low-sulfur natural gas pipeline transportation. The gas is then transported to a low-sulfur natural gas purification plant for desulfurization. Specifically, existing methods of blending high-sulfur natural gas with low-sulfur natural gas or purified product-grade natural gas at specific ratios using gas manifolds result in uneven hydrogen sulfide content in the mixed gas. This leads to variations in hydrogen sulfide concentration, causing columnar and laminar flow phenomena, which in turn increase the frequency of operational failures at the low-sulfur natural gas purification plant. Utility Model Content

[0004] In view of the above-mentioned defects in the prior art, the purpose of this utility model is to provide a high-efficiency mixing processor for natural gas gathering and transportation, so that the mixed natural gas after mixing high-sulfur natural gas and low-sulfur natural gas no longer exhibits column flow or laminar flow phenomena with varying hydrogen sulfide content, thus ensuring the stable operation of the low-sulfur natural gas purification plant.

Detailed Implementation

[0054] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0055] Example 1:

[0056] like Figures 1 to 5 As shown, the high-efficiency hybrid processor for natural gas gathering and transportation includes:

[0057] Mixed outer tube, top closed;

[0058] The mixing inner tube has openings at both the top and bottom ends and is installed inside the mixing outer tube. The lower end is seamlessly connected to the inner wall of the mixing outer tube, dividing the mixing outer tube into an upper cavity 18 and a lower cavity 19.

[0059] The first intake pipe 3 is connected to the upper cavity 18 of the mixing outer pipe;

[0060] The second air intake pipe 4 is connected to the upper cavity 18 of the mixing outer pipe;

[0061] The first flow stabilizer is installed in the upper cavity 18 of the mixing outer tube, and is wrapped around the outer wall of the mixing inner tube. It is located above the connection between the first air inlet pipe 3 and the mixing outer tube and the connection between the second air inlet pipe 4 and the mixing outer tube.

[0062] The second flow stabilizer is installed in the lower cavity 19 of the mixing outer tube;

[0063] The exhaust pipe 7 is connected to the lower cavity 19 of the mixing outer pipe.

[0064] In this embodiment, the first intake pipe 3 is provided with a first spiral blade 31, and the outer end face of the first spiral blade 31 is seamlessly connected to the inner wall of the first intake pipe 3.

[0065] The second intake pipe 4 is provided with a second spiral blade 41. The outer end face of the second spiral blade 41 is seamlessly connected to the inner wall of the second intake pipe 4. The second spiral blade 41 rotates in the opposite direction to the first spiral blade 31.

[0066] In this embodiment, the axes of the first intake pipe 3 and the second intake pipe 4 are collinear; the first intake pipe 3 and the second intake pipe 4 are offset on the axis of the mixing outer pipe.

[0067] The staggered arrangement can prevent the gases discharged from the first intake pipe 3 and the second intake pipe 4 from impacting each other head-on, thus increasing the discharge resistance of the first intake pipe 3 and the second intake pipe 4.

[0068] In this embodiment, the first current stabilizer includes:

[0069] Several first concentric circular tubes 51 of equal height are coaxially arranged around the axis of the mixed inner tube; the upper and lower end faces of the first concentric circular tubes 51 are rounded with two side faces.

[0070] A plurality of first connecting plates 52 connect a plurality of first concentric circular tubes 51 together; the surface of the first connecting plate 52 is parallel to the axis of the mixing inner tube; the length of the first connecting plate 52 is the same as the height of the first concentric circular tube 51; the end face of the first connecting plate 52 is flush with the end face of the first concentric circular tube 51; the upper and lower end faces of the first connecting plate 52 are both rounded with the two side faces.

[0071] In this example, the second current stabilizer includes:

[0072] Several second concentric circular tubes 61 of equal height are coaxially arranged around the axis of the mixing inner tube; the upper and lower end faces of the second concentric circular tubes 61 are rounded with two side faces.

[0073] A plurality of second connecting plates 62 connect a plurality of second concentric circular tubes 61 together; the surface of the second connecting plate 62 is parallel to the axis of the mixing outer tube; the length of the second connecting plate 62 is the same as the height of the second concentric circular tube 61; the end face of the second connecting plate 62 is flush with the end face of the second concentric circular tube 61; the side of the outermost second connecting plate 62 is fixed to the inner wall of the mixing outer tube, and the upper and lower end faces of the second connecting plate 62 are both rounded at the two side faces.

[0074] In this embodiment, the mixing inner tube includes:

[0076] The expansion section 22 is in the shape of an inverted funnel. Its upper opening is seamlessly connected to the lower end of the straight pipe section 21, and its lower end is seamlessly connected to the inner wall of the mixing outer pipe. The connection between the lower end and the inner wall of the mixing outer pipe divides the mixing outer pipe into an upper cavity 18 and a lower cavity 19. The upper end of the second flow stabilizer is in contact with the lower end of the expansion section 22.

[0077] The expansion section 22 reduces the airflow pressure, allowing the gas to be mixed again during the pressure release process.

[0078] In this embodiment, guide protrusions 8 are provided at the connection between the inner wall of the mixing outer pipe and the first air inlet pipe 3 and at the connection between the inner wall of the mixing outer pipe and the second air inlet pipe 4.

[0079] The upper end face and the outer surface of the mixing inner tube are rounded, and an annular drainage protrusion is provided at the junction of the upper end face and the inner wall of the mixing inner tube.

[0080] The top and inner wall of the mixing outer tube are rounded.

[0081] By rounding the corners of the guide protrusion 8, the drainage protrusion, and all components in contact with the airflow, the decibel level of the whistling sound generated when the airflow passes through the above areas can be reduced, thus lowering the noise level and reducing the flow resistance of the airflow.

[0082] In this embodiment, the hybrid outer tube includes:

[0083] The pipe body 11 is internally provided with a mixing inner pipe, a first flow stabilizer, and a second flow stabilizer. The first air inlet pipe 3 and the second air inlet pipe 4 are connected to the inside of the pipe body 11.

[0084] The pipe cover 12 is fastened to the upper end of the pipe body 11 via a flange, thereby sealing the upper end of the pipe body 11.

[0085] The arc bend 13 is bent at 90 degrees, with the same inner diameter as the inner diameter of the pipe body 11, and one end is seamlessly connected to the lower flange of the pipe body 11.

[0086] The straight pipe 14 has the same inner diameter as the pipe body 11, and one end is seamlessly connected to the other end of the arc bend pipe 13.

[0087] The necked tube 15 has the same inner diameter as the straight tube 14 at the larger opening end, and the larger opening end is seamlessly connected to the other end of the straight tube 14.

[0088] The end tube 16 has the same inner diameter as the smaller opening end of the constricted tube 15. One end is seamlessly connected to the smaller opening end of the constricted tube 15, and the other end is seamlessly connected to the vent tube 7.

[0089] The third flow stabilizer is installed in the straight pipe 14, the necked pipe 15 and the end pipe 16 to guide the stable flow of the mixer to the outlet pipe 7.

[0090] The two ends of the pipe body 11 are connected to the pipe cover 12 and the arc bend 13 via flanges, facilitating disassembly and maintenance. The mixed gas is pressurized and stably delivered to the outlet pipe 7 through the necked pipe 15 and the third flow stabilizer.

[0091] In this embodiment, the third current stabilizer includes:

[0092] The guide pipe 171 is disposed inside the straight pipe 14, the necked pipe 15 and the end pipe 16, and is coaxially arranged with the straight pipe 14; the guide pipe 171 includes an air inlet, a necked section and a horizontal flow section in sequence along the flow direction of the mixed airflow; the air inlet and horizontal flow sections are both circular tubes, and the necked section is funnel-shaped;

[0093] Several fixing plates 172 are disposed on the outer surface of the guide tube 171 and are fixedly connected to the inner walls of the straight tube 14, the necked tube 15 and the end tube 16.

[0094] In this embodiment, the high-efficiency hybrid processor for natural gas gathering and transportation works as follows: the first intake pipe 3 is connected to high-sulfur natural gas, and the second intake pipe 4 is connected to low-sulfur natural gas.

[0095] After being guided by the first helical blade 31, the high-sulfur natural gas enters the mixing outer pipe in a clockwise spiral airflow; after being guided by the second helical blade 41, the low-sulfur natural gas enters the mixing outer pipe in a counterclockwise spiral airflow. The two streams of natural gas come into contact and, due to their different rotation directions, begin to mix.

[0096] The initially mixed natural gas flows upward, passing through the first flow stabilizer. After being guided by the first concentric circular pipe 51 and the first connecting plate 52, it flows steadily upward. Subsequently, the initially mixed natural gas turns downward and enters the mixing inner pipe. During this process, the gas is mixed again. Finally, guided by the third spiral blade 23, the gas flows downward in a clockwise direction into the expansion section 22. The gas flow is disturbed again and finally enters the second flow stabilizer. After being guided by the second concentric circular pipe 61 and the second connecting plate 62, it sequentially enters the arc bend 13, the straight pipe 14, the necking pipe 15, and the end pipe 16, finally entering the outlet pipe 7. During this process, the gas flow is compressed and pressurized by the necking pipe 15. At the same time, after the gas flow is disturbed at the arc bend 13, it is guided by the guide pipe 171 and the fixed plate 172 in the third turbulence device, and flows steadily into the outlet pipe 7. Finally, it is transported to the downstream gathering station or natural gas purification plant for processing.

[0097] Example 2:

[0098] like Figure 6 , Figure 7 As shown, the only difference between this embodiment and Embodiment 1 is that the axes of the first intake pipe 3 and the second intake pipe 4 are coplanar; the angle between the first intake pipe 3 and the second intake pipe 4 on the axis of the mixing outer pipe is 60 degrees.

[0099] The high-sulfur natural gas and low-sulfur natural gas discharged from the first intake pipe 3 and the second intake pipe 4 collide at a small angle, achieving mixing without excessively increasing the discharge resistance of the first intake pipe 3 and the second intake pipe 4. At the same time, when the first intake pipe 3 and the second intake pipe 4 are at the same horizontal height, the height of the pipe body 11 can be reduced, making the overall volume of this utility model smaller.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
