Description

Technical Field

[0001] This invention relates to the field of oil and gas separation technology, specifically to a novel oil and gas separation structure and method. Background Technology

[0002] Because transformers inevitably produce gases, moisture, and impurities during operation, which can affect their service life and efficiency, it is necessary to degas the transformer oil to solve the problem of gaseous impurities generated during transformer operation.

[0003] In this process, transformer oil vacuum degassing technology is generally used. This technology involves heating the transformer oil to a certain temperature and then removing gases, moisture, and impurities from the oil through vaporization and evaporation under a vacuum environment. This achieves the purpose of purifying the transformer oil and improving the service life and efficiency of the transformer.

[0004] In transformer oil vacuum degassing technology, the equipment used consists of an air pump, heater, oil tank, oil pump, oil pipeline, air pipeline and filter, etc. The working process of the equipment is divided into several stages such as heating pretreatment, vacuum evaporation and oil purification cooling.

[0005] First, the transformer oil needs to be heated to a certain temperature before degassing, generally 70℃-90℃. Then, the air pump is started to reduce the pressure in the oil tank to a certain vacuum level (below 10Pa) so that the gas, moisture and impurities in the oil can be discharged by the vaporization and evaporation of the oil. Finally, in the clean oil cooling stage, after the clean oil is cooled to the ambient temperature, the oil pump sends the clean oil back into the transformer.

[0006] However, the above process is inefficient, requiring a long heating and vacuuming process, followed by cooling before the transformer oil can be reused. This low efficiency causes inconvenience to users. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a novel oil-gas separation structure and method, aiming to solve the aforementioned problems.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A novel oil-gas separation structure includes a storage tank and further includes:

[0010] The oil pipeline is connected at one end to the bottom of the storage tank;

[0011] The gas pipeline is connected at one end to the top of the storage tank;

[0012] A shared pipeline is used, with one end connected to the bottom of the storage tank;

[0013] A three-way pipe has three connecting ends that are respectively connected to the other end of the oil pipeline, the gas pipeline, and the common pipeline;

[0014] The oil pump is located at the common pipeline.

[0015] Preferably, a first valve is provided at the oil pipeline.

[0016] Preferably, the gas pipeline is branched with a discharge pipe, a second valve is installed at the discharge pipe, and a third valve and a flow meter are installed on the side of the gas pipeline near the tee pipe.

[0017] The second valve is a check valve.

[0018] A novel oil-gas separation method, comprising the following separation steps:

[0019] Step 1: Open the first valve and the third valve, and start the oil pump at the same time to generate suction;

[0020] Step 2: Through the influence of suction, the oil is made to return to the storage tank through the oil pipeline and the common pipeline, forming an oil circulation.

[0021] At the same time, the gas will return to the interior of the storage tank through the gas pipeline and the shared pipeline, forming a gas circulation;

[0022] Step 3: Oil circulation drives gas circulation, causing oil and gas to mix at the three-way pipe, resulting in an incomplete mixture.

[0023] Step 4: The incomplete mixture moves upward through a shared pipeline and oil pump, generating bubbles to form bubbling degassing;

[0024] During the bubbling degassing process, small gas particles contained in the oil are drawn out by the bubbles, thus completing the oil-gas separation operation.

[0025] Step 5: Once the oil-gas separation reaches the expected standard, shut off the oil pump, the first valve, and the third valve.

[0026] Preferably, during the upward movement of the incomplete mixture, the oil will settle to a certain extent due to gravity, while the gas will rise relatively, thereby generating bubbles and achieving the effect of bubbling degassing.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention provides a novel oil-gas separation structure and method that not only eliminates the need for an air pump, thus increasing its service life, but also rapidly removes gas from the oil using a bubbling degassing method, facilitating quick oil-gas separation operations, increasing degassing efficiency and convenience, and making it easier for users to operate.

One end of the oil pipeline 20 is connected to the bottom of the storage tank 10, one end of the gas pipeline 30 is connected to the top of the storage tank 10, one end of the common pipeline 40 is connected to the bottom of the storage tank 10, and the three connecting ends of the tee pipe 50 are respectively connected to the other ends of the oil pipeline 20, the gas pipeline 30, and the common pipeline 40. The oil pump 60 is located at the common pipeline 40.

[0033] Meanwhile, a first valve 21 is installed at the oil pipeline 20, and a discharge pipe 31 is connected to the gas pipeline 30. The discharge pipe 31 is equipped with a second valve 32, which is a one-way valve. A third valve 33 and a flow meter 34 are installed on the side of the gas pipeline 30 near the three-way pipe 50.

[0034] The first valve 21 and the second valve 32 are electric valves, and the flow meter 34 is an ammeter. They are connected and controlled in the existing manner during use.

[0036] Step 1: Open the first valve 21 and the third valve 33, and start the oil pump 60 at the same time to generate suction.

[0037] Step 2: Through the influence of suction, the oil returns to the storage tank 10 after passing through the oil pipeline 20 and the common pipeline 40, forming an oil circulation.

[0038] At the same time, the gas will return to the interior of the storage tank 10 after passing through the gas pipeline 30 and the common pipeline 40, forming a gas circulation;

[0039] Step 3: Oil circulation drives gas circulation, causing oil and gas to mix at point 50 of the three-way pipe, resulting in an incomplete mixture.

[0040] Step 4: The incomplete mixture moves upward through the common pipe 40 and oil pump 60, generating bubbles to form bubbling degassing;

[0041] During the bubbling degassing process, small gas particles contained in the oil are drawn out by the bubbles, thus completing the oil-gas separation operation.

[0042] Step 5: Once the oil-gas separation reaches the expected standard, shut off oil pump 60, first valve 21, and third valve 33.

[0043] Preferably, during the upward movement of the incomplete mixture, the oil will settle to a certain extent due to gravity, while the gas will rise relatively, thereby generating bubbles and achieving the effect of bubbling degassing.

[0044] In summary, the novel oil-gas separation structure and method provided by this invention not only eliminates the need for an air pump, increasing its service life, but also rapidly removes gas from the oil using a bubbling degassing method, facilitating rapid oil-gas separation operations, increasing degassing efficiency and convenience, and making it easier for users to operate.
