Description

Technical Field

[0001] This utility model belongs to the technical field of oil-gas separators, specifically relating to a multi-stage induction heating anti-condensation device for a high-pressure oil-gas separator. Background Technology

[0002] In the extraction and processing of oil and natural gas, high-pressure oil-gas separators are one of the key pieces of equipment. Their main function is to separate oil and gas mixtures into gas and liquid phases for subsequent storage, transportation, and processing. However, during high-pressure oil-gas separation, due to pressure changes and heat exchange, some components in the oil-gas mixture are prone to condensation due to temperature drops, forming droplets or solid deposits that adhere to the inner wall of the separator. This not only reduces separation efficiency but may also lead to problems such as equipment blockage and corrosion, affecting the normal operation and service life of the equipment.

[0003] A prior art patent, CN221195160U, describes a compound oil-gas separator. This patent includes an oil-gas separator body, an inlet pipe connected to one side of the body, a filter element connected inside the body, a fixing plate installed inside the body above the filter element, an oil drip pipe connected to the bottom of the body, and a motor connected to the top of the support plate. Through this series of structures, it can remove odors from the separated oil-gas before discharging it to the outside, reducing pollution to the ambient air. While the oil-gas separator is effective, it still has the following shortcomings in practical use: In reality, when the ambient temperature is low, the water vapor in these mixed gases will condense into water droplets and adhere to the cavity wall of the oil-gas separator. Under the action of gravity, these water droplets will flow to the lower part of the cavity of the oil-gas separator joint, resulting in a large amount of water accumulating in the oil-gas separator and affecting the use of the equipment. Moreover, when the water droplets and oil droplets pass through the output pipe, the low temperature will cause these condensates to adhere to the inner wall of the pipe, gradually reducing the flow cross-sectional area and even forming a complete blockage, which seriously affects the continuity of production.

[0004] Therefore, a multi-stage induction heating anti-condensation device for high-pressure oil-gas separators is needed to solve the problems existing in the prior art, such as water vapor condensing into water droplets and adhering to the cavity wall of the oil-gas separator, and water droplets and oil droplets adhering to the inner wall of the pipe when the temperature is too low as they pass through the output pipe.

[0009] Furthermore, it should be noted that the electromagnetic induction coil is made of hollow copper tube, with water inlet and outlet pipes connected to both ends of the hollow copper tube to form a cooling water circuit.

[0010] In a preferred embodiment, the oil conveying mechanism consists of an oil conveying pipe, a second heat insulation layer, a water inlet, and a water outlet. The top end of the oil conveying pipe is threaded to the bottom of the oil outlet pipe.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-3 This utility model provides a multi-stage induction heating anti-condensation device for a high-pressure oil-gas separator, including an outer shell 1, an air inlet pipe 2, an oil outlet pipe 3, an air outlet pipe 4, an oil-gas separation mechanism 5, a heating component 6, and an oil delivery mechanism. The air inlet pipe 2 is fixedly connected to the left side of the outer shell 1, the oil outlet pipe 3 is fixedly connected to the lower part of the outer shell 1, and the air outlet pipe 4 is fixedly connected to the upper part of the outer shell 1. The oil-gas separation mechanism 5 is disposed inside the outer shell 1, the heating component 6 is disposed outside the outer shell 1, and the oil delivery mechanism 7 is disposed below the oil outlet pipe 3.

[0023] Further as Figure 1 , Figure 2and Figure 3 As shown, it is worth noting that the heating component 6 consists of an electromagnetic induction coil 601, a heat insulation layer 602, and a temperature sensor 604. The electromagnetic induction coil 601 is wound and connected to the outside of the outer shell 1, the heat insulation layer 602 is fixedly connected to the outside of the outer shell 1, an oil outlet pipe 3 is provided between the heat insulation layer 602 and the outer shell 1, and the electromagnetic induction coil 601 is installed inside the structural cavity 603.

[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the temperature sensor 604 is fixedly connected to the inside of the housing 1 to monitor the temperature inside the housing 1 in real time. The inner wall of the housing 1 is provided with a temperature sensing coating, which works in conjunction with the temperature sensor 604.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the electromagnetic induction coil 601 is made of a hollow copper tube, and the two ends of the hollow copper tube are respectively connected to an inlet water pipe and an outlet water pipe to form a cooling water circuit.

[0026] The electromagnetic induction coil 601 is made of hollow copper tube. When energized, it generates an induced magnetic field, which heats up the outer casing 1 and the internal oil-gas mixture. At the same time, the cooling water circuit carries away the excess heat generated by the coil through the hollow copper tube, preventing the coil from overheating and being damaged, and extending its service life.

[0027] As can be seen from the above working process, the electromagnetic induction coil 601 heats the outer shell 1, and in conjunction with the hot water heating in the flow chamber 702 of the oil conveying mechanism 7, a multi-stage heating system is formed, which can effectively prevent condensation during the oil-gas separation process and the oil conveying process, and ensure the smoothness of separation and conveying.

[0028] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the oil conveying mechanism 7 consists of an oil conveying pipe 701, a second heat insulation layer 703, a water inlet 704, and a water outlet 705. The top end of the oil conveying pipe 701 is threaded to the bottom of the oil outlet pipe 3. A flow cavity 702 is provided inside the oil conveying pipe 701, and the second heat insulation layer 703 is provided on the outside of the oil conveying pipe 701.

[0029] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the inlet pipe 704 is fixedly connected to the upper right side of the flow chamber 702, and the outlet pipe 705 is fixedly connected to the lower right side of the flow chamber 702. The inlet pipe 704 is connected to an external hot water pipe.

[0030] Hot water introduced through the inlet 704 flows in the flow chamber 702, heating and keeping the oil in the oil pipeline 701 warm, preventing the oil from condensing due to temperature drop during transportation.

[0031] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the heat insulation layer 602 and the heat insulation layer 703, from the inside out, include a high-temperature resistant insulation layer, a heat insulation cotton layer and a metal protective shell, with the high-temperature resistant insulation layer wrapped around the outside of the electromagnetic induction coil 601.

[0032] The multi-layer structure of the heat insulation layer 602 and the heat insulation layer 703 effectively reduces heat loss, improves heating and insulation effects, and reduces energy consumption.

[0033] A controller 8 is fixedly connected to the outside of the thermal insulation layer 602. The controller 8 has a power adjustment module inside. The controller 8 is electrically connected to the temperature sensor 604, and the power adjustment module is electrically connected to the electromagnetic induction coil 601.

[0034] The oil-gas separation mechanism 5 has been described in detail in the utility model with patent publication number CN221195160U. It is used to separate oil and gas in the exhaust gas entering through the air inlet pipe 2, and will not be described in detail here.

[0035] This solution has the following working process: During use, a high-pressure oil-gas mixture enters the interior of the outer casing 1 through the air inlet pipe 2. Under the action of the oil-gas separation mechanism 5, the oil and gas begin to separate. The separated oil droplets collect downwards, while the gas moves upwards. The temperature sensor 604 monitors the temperature inside the outer casing 1 in real time and transmits the data to the controller 8. When the internal temperature is lower than the preset value and there is a risk of condensation, the controller 8 activates the electromagnetic induction coil 601 through the power adjustment module. The heat insulation layer 602 on the outside of the outer casing 1 plays a role in reducing heat loss from the outer casing 1, maintaining a stable internal temperature, and improving heating efficiency.

[0036] The separated oil enters the oil conveying pipe 701 of the oil conveying mechanism 7 through the oil outlet pipe 3. At this time, the hot water introduced through the water inlet 704 flows in the flow chamber 702 to heat and keep the oil in the oil conveying pipe 701 warm, preventing the oil from condensing due to temperature drop during transportation; the heat insulation layer 703 on the outside of the oil conveying pipe 701 further reduces heat loss and ensures smooth oil transportation; the separated gas is discharged from the outer shell 1 through the gas outlet pipe 4.

[0037] Throughout the operation, the controller 8 dynamically adjusts the power of the electromagnetic induction coil 601 through the power regulation module based on the real-time temperature feedback from the temperature sensor 604, so that the internal temperature of the outer casing 1 is always maintained within a reasonable range. When the device stops running, the oil and gas input is first shut off. After the internal oil and gas separation is completed and the temperature drops to a safe range, the controller 8 is shut off, and the power supply to the electromagnetic induction coil 601 and the water supply to each circuit are cut off.

[0038] In summary: The electromagnetic induction coil 601 heats the outer casing 1, which, in conjunction with the hot water heating in the flow chamber 702 of the oil conveying mechanism 7, forms a multi-stage heating system. This effectively prevents condensation during oil-gas separation and oil transportation, ensuring smooth separation and transportation. The temperature sensor 604, in conjunction with the controller 8 and the temperature-sensing coating on the inner wall of the outer casing, can monitor and precisely control the internal temperature of the outer casing 1 in real time, preventing excessively high or low temperatures. This ensures both anti-condensation and energy conservation. Simultaneously, the first thermal insulation layer 602 and the second thermal insulation layer 703 effectively reduce heat loss, further lowering energy consumption.
