Description

Technical Field

[0001] This invention relates to the field of natural gas component mixing technology, specifically to an auxiliary device for testing the mixing and transportation of natural gas components from multiple gas sources. Background Technology

[0002] Synthetic natural gas (SMU) is a technology that converts carbon-containing resources into methane using appropriate equipment based on the methanation reaction principle. my country's energy resources are characterized by low oil and gas reserves and abundant coal. Coal resources are relatively plentiful, and fully utilizing inexpensive coal resources to produce natural gas offers high energy efficiency and low water consumption per unit of calorific value, making it an important way to solve my country's natural gas supply and demand imbalance. Furthermore, utilizing CO2 and biomass resources to produce natural gas not only broadens the utilization of CO2 and biomass but also significantly reduces greenhouse gas emissions. Synthetic natural gas technologies mainly include direct coal-to-natural gas synthesis, coal-to-natural-gas synthesis, bio-based natural gas synthesis, CO2 methanation-to-natural-gas synthesis, and coke oven gas-to-natural-gas synthesis. Chinese patent "CN202011364384.7" discloses an experimental measuring device for the mixing effect of hydrogen in urban natural gas, which proposes that by giving the volume fraction ratio of two sets of gases, the effect of mixing different proportions of hydrogen and natural gas can be measured in real time.

[0003] As can be seen from the above-described apparatus, although the above preparation method provides a way to obtain different mixing effects with different mixing ratios, the applicant believes that the following drawbacks still exist:

[0004] Existing auxiliary devices for testing and transporting mixed natural gas components inject multiple gases into a single container for mixing without liquefying them before mixing. This results in excessive pressure inside the container and incomplete mixing. Furthermore, the internal pressure can only be assessed using pressure gauges on the external surface, and valves cannot be automatically closed based on internal space and pressure, leading to incomplete mixing and potential hazards. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an auxiliary device for testing and transporting multi-source natural gas components. This device, through the cooperation of a cooling component and a compressor, allows natural gas from multiple sources to be compressed in a specific ratio before entering a liquefaction chamber. The liquefaction is then cooled and liquefied by the cooling component before mixing. In liquefaction mixing, compared to gas mixing, the molecules in the liquid are closer together, allowing for more frequent collisions and interactions. This liquefaction mixing achieves uniform mixing of substances, enabling contact and exchange between components for better mixing results. This invention solves the problems of existing multi-source natural gas component mixing and transporting auxiliary devices, which, when mixing natural gas components, simply inject multiple gases into a single container without liquefying them, leading to excessive pressure and incomplete mixing. Furthermore, the internal pressure can only be assessed using pressure gauges on the external surface, without the ability to automatically close valves based on internal space and pressure, resulting in incomplete mixing and potential hazards.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides an auxiliary device for testing the mixing and transportation of multi-source natural gas components, which has the following advantages:

[0019] 1. This multi-source natural gas component mixing and transportation test auxiliary device, through the cooperation between the cooling component and the compressor, achieves the function of compressing natural gas from multiple gas sources into the compressor in proportion, then entering the liquefaction chamber, where it is cooled and liquefied by the cooling component, and then mixed. In liquefaction mixing, compared with gas phase mixing, the molecular distance of liquid is closer, and the molecules can collide and interact more frequently. Liquefaction mixing can achieve uniform mixing between substances, allowing each component to come into contact and exchange with each other, achieving a better mixing effect.

[0020] 2. This multi-source natural gas component mixing and transportation testing auxiliary device, through the cooperation of a buoyancy automatic valve closing mechanism and a liquid pressure relief and gas release mechanism, achieves the following: gas provides buoyancy to the float through liquefied liquid. The float drives the cover plate to move upward within a long slide rail. When the liquid reaches a set threshold, the magnetic block on the upper surface of the cover plate attracts the electromagnet, sealing the two valves. After sealing, the compressor is powered off and closes the valves of the three gas tanks. When the float rises to a specific value, the push rod drives the small slider to move upward within a short slide rail. The small slider drives the isolation plate to rise synchronously, allowing the liquefied gas to enter the vaporization chamber through the isolation hole. Due to the different gas pressures in the two chambers, the liquid turns back into gas after entering the vaporization chamber and then enters the testing device through the detection tube for detection. Compared with existing devices that can only judge the mixing and internal conditions through pressure gauges and detection ports, this device achieves the function of automatically opening and closing valves for mixing and testing.

[0044] The complete usage steps and working principles of the above embodiments one to four are as follows:

[0045] Before mixing the multi-source natural gas components, the workers first open the valves of natural gas tank 2, biogas tank 24, and syngas tank 25 in sequence. Natural gas tank 2 is opened first, with natural gas accounting for more than 70% of the volume. The remaining part will be occupied by biogas and syngas. The three gases are introduced into compressor 23 in proportion through gas pipe 22 to compress the gas. Part of the gas compressed by compressor 23 will be liquefied. The liquefied volume and the unliquefied gas after compression enter the liquefaction chamber 110 of liquefaction storage tank 1 through drain pipe 28. The temperature is controlled below -160℃ by the cooling component 3 installed inside liquefaction storage tank 1 to further liquefy the compressed gas. The liquefied gas will be mixed in liquefaction chamber 110. The unliquefied gas, being lighter than air, enters compressor 23 again through inlet pipe 27 for compression. After secondary compression, it enters liquefaction storage tank 1 for cooling and liquefaction.

[0046] Furthermore, as the liquefied liquid slowly mixes and rises within the liquefaction chamber 110, the liquid drives the floats 47 to rise as well. The two floats 47, with their significant buoyancy, drive the first connecting rod 43 to rise. Through the large sliders 42 fixedly connected to both ends of the first connecting rod 43, the two large sliders 42 drive the first connecting rod 43 to move within the inner surface of the long slide rail 41. As the water level slowly rises, the floats 47 drive the first connecting rod 43 to rise together. When the water level reaches the threshold, the first connecting rod 43 drives the cover plate 49 to move to the lower surface of the water vapor separator 12 and the water inlet 13. When the compressor 23 starts working, the electromagnets 6 on the lower surface of the water vapor separator 12 and the water inlet 13 are energized and magnetized. When the cover plate 49 moves nearby, the magnetic block 410 attracts the electromagnet 6, sealing the water vapor separator 12 and the water inlet 13 through the first sealing ring 411. At this time, the compressor 23 is de-energized.

[0047] Furthermore, as the float 47 drives the large slider 42 to rise, the large slider 42, installed on the outer surface of the partition 112 on the right, drives the long rod 51 to move upward simultaneously. When the long rod 51 moves to below the section slide rail 55, the top rod 52 enters the top groove 53 set on the lower surface of the small slider 54, driving the small slider 54 to move upward on the inner surface of the short slide rail 55. The small slider 54 drives the isolation plate 58 to move together through the third connecting rod 57. The isolation plate 58 moves upward on the inner surface of the wheel axle 510 through the pulley 511. When the isolation plate 58 moves upward, the two isolation holes 113 set on the outer surface of the partition 112 gradually leak out. The natural gas mixed in the liquefaction chamber 110 enters the gasification chamber 110. After the liquid enters the gasification chamber 110, it turns into gas due to the pressure difference. The gas is discharged through the detection tube 16 and enters the testing device for detection.
