Description

Technical Field

[0001] This utility model relates to the field of oil-gas separation technology, specifically to an oil-gas separation device for oil chromatography analysis. Background Technology

[0002] With the rapid development of my country's power industry, the level of power equipment has been continuously improved, and the power capacity and voltage level have steadily increased, greatly enhancing the safety of power use and protecting people's lives and property. However, due to the advancement of power levels, power detection methods also need continuous improvement to meet the requirements of modern power detection. Online chromatographic analysis is an important means of analyzing oil and gas in power transformers, which involves analyzing transformer fault gases such as H2, CO, CO2, CH4, C2H6, and C2Hz. In online transformer oil fault gas analysis, oil-gas separation is a crucial separation step.

[0003] According to application number 201721694683.0, an oil-gas separation device for oil chromatography analysis includes an oil cylinder with an exhaust port at the top and an oil inlet on the side wall. It also includes a piston rod, an electric push rod, and a displacement gauge. A connecting plate is provided on the electric push rod, with one end connected to the piston rod and the other end connected to a scale rod. The scale rod and the displacement gauge are arranged vertically side-by-side, and the displacement gauge has a liquid level scale. The piston rod includes a first plug and a first rod body. The first plug is vertically connected to the end of the first rod body, and the first rod body passes through an opening at the bottom of the oil cylinder and is connected to the connecting plate. The first plug is located inside the oil cylinder, and its outer periphery is in a sealing sliding fit with the inner wall of the oil cylinder.

[0004] By repeatedly extending and retracting the electric actuator, the transformer oil in the cylinder is compressed, separating the air from the transformer oil. This solves the problem that the transformer oil will crack into gases such as C2H2O during the stirring process, causing errors in subsequent detection. If the device cannot filter the separated oil, impurities in the oil will affect the analysis of the oil using oil chromatography. Utility Model Content

[0015] Compared with the prior art, this utility model provides an oil-gas separation device for oil chromatography analysis, which has the following beneficial effects:

[0016] This oil-gas separation device for oil chromatography uses a filtration mechanism. Separated oil enters the housing through the first discharge pipe, where filter plates filter the oil, blocking impurities. The filtered oil is then discharged through the second discharge pipe. To replace the filter plates, first pull the pull plate to move the second connecting plate forward. The second connecting plate then moves the fixing block away from the front of the filter plate. Next, rotate the first connecting plate so that the fixing block is no longer in front of the filter plate. Then, pull the old filter plate out of the groove and slide the new filter plate into the groove. Then, rotate the second connecting plate in the opposite direction so that the fixing block is in front of the filter plate. Finally, release the pull plate; the fixing block, through the spring force, adheres tightly to the front of the filter plate, thus securing it.

[0017] This oil-gas separation device for oil chromatography uses a separation mechanism. The first discharge pipe is blocked by a valve, and the oil-gas mixture is then injected into the tank through the inlet pipe. After injection, the inlet pipe is blocked again. The motor is then started, causing the screw to rotate back and forth, which in turn causes the screw block to move up and down. The screw block drives the disc and sealing ring to move up and down, changing the pressure difference within the tank, thus separating the oil-gas mixture. Once complete separation, the motor is stopped, the inlet pipe valve is opened, and a vacuum pump extracts the gas from the tank. After extraction, the first discharge pipe valve is opened, and the oil flows into the tank through the first discharge pipe. Attached Figure Description

[0032] A valve is fixedly installed on the surface of the first discharge pipe 6, and the bottom end of the first discharge pipe 6 is fixedly connected to the top of the box 712.

[0033] The replacement component 72 includes a connecting rod 721, which is fixedly connected to the front of the housing 712. A first connecting plate 722 is rotatably connected to the front end of the connecting rod 721. A connecting frame 723 is fixedly connected to the front of the first connecting plate 722. A first guide rod 724 is provided on the front of the connecting frame 723. A pull plate 729 is fixedly connected to the front end of the first guide rod 724.

[0034] The front of the connecting frame 723 has a groove corresponding to the first guide rod 724, and the surface of the first guide rod 724 is slidably connected to the groove. The front end of the spring 726 is fixedly connected to the back of the connecting frame 723.

[0035] Please see Figure 5-6 Furthermore, based on Example 1, a separation mechanism 8 was obtained.

[0036] The separation mechanism 8 includes a motor 81, which is fixedly connected to the top of the fixed frame 2. A screw 82 is fixedly connected to the output end of the motor 81. A screw block 83 is threadedly connected to the surface of the screw 82. Fixed rods 84 are fixedly connected to the bottom of the screw block 83 symmetrically. A disc 85 is fixedly connected to the bottom of the fixed rod 84. A sealing ring 86 is fixedly connected to the surface of the disc 85. A feed pipe 87 is fixedly connected to the top of the disc 85. Limiting rods 88 are fixedly connected to the top of the screw block 83 symmetrically.

[0037] The diameter of disc 85 is smaller than the inner diameter of tank 5, and the diameter of sealing ring 86 is equal to the inner diameter of tank 5.

[0038] The top of the fixed frame 2 has a groove corresponding to the limiting rod 88, and the surface of the limiting rod 88 is slidably connected to the groove. The limiting rod 88 limits the screw block 83 so that the screw block 83 can only move up and down.

[0039] In actual operation, when this device is in use, the separated oil enters the housing 712 through the first discharge pipe 6. The filter plate 715 in the housing 712 filters the oil and blocks impurities in the oil. The filtered oil is discharged through the second discharge pipe 713. When replacing the filter plate 715, first pull the pull plate 729 to move the second connecting plate 725 forward. The second connecting plate 725 will drive the fixing block 728 away from the front of the filter plate 715. Then rotate the first connecting plate 722 so that the fixing block 728 is not in front of the filter plate 715. Then pull the old filter plate 715 out of the slide groove 714 and slide the new filter plate 715 into the slide groove 714. Then rotate the second connecting plate 725 in the opposite direction so that the fixing block 728 is in front of the filter plate 715. Then release the pull plate 729. The fixing block 728 is pressed tightly against the front of the filter plate 715 by the elastic force of the spring 726 to fix the filter plate 715.

[0040] The first discharge pipe 6 is blocked by a valve. Then, the oil-gas mixture is injected into the tank 5 through the inlet pipe 87. After injection, the inlet pipe 87 is blocked by a valve. Then, the motor 81 is started. The operation of the motor 81 causes the screw 82 to rotate back and forth, which in turn causes the screw block 83 to move up and down. The screw block 83 drives the disc 85 and the sealing ring 86 to move up and down, changing the pressure difference in the tank 5, thereby separating the oil-gas mixture in the tank 5. When the oil-gas is completely separated, the operation of the motor 81 is stopped, the valve of the inlet pipe 87 is opened, and the gas in the tank 5 is extracted by a vacuum pump. After extraction, the valve of the first discharge pipe 6 is opened, and the oil flows into the box 712 through the first discharge pipe 6.
