[0001] This application relates to the field of sampling equipment technology, and in particular to a sampling device with oil heating function. Background Technology
[0002] The purpose of oil sampling is to analyze the extracted sample oil to estimate and infer relevant characteristic parameters of the oil. However, conventional oil sampling equipment is mostly designed based on the flow characteristics of ordinary oils, and does not adequately consider the special requirements of high-viscosity oils, such as heavy crude oil, certain lubricating oil base oils, and industrial high-viscosity oils. These oils have complex molecular structures and strong intermolecular interactions. High-viscosity oils have low flow rates and poor flow in pipelines, and are prone to frequent clogging and other malfunctions in high-viscosity oil applications, which cannot meet the needs of modern industry for efficient sampling.
[0003] Therefore, this application proposes a sampling device with oil heating function, which is suitable for reducing the viscosity of oil, increasing the flow rate of oil, and improving sampling efficiency. Summary of the Invention
[0004] In view of this, this application proposes a sampling device with oil heating function.
[0005] According to one aspect of this application, a sampling device with oil heating function is provided, characterized in that it includes: an oil heater, an oil inlet pipe, an oil outlet pipe, and a sampler;
[0006] The oil inlet of the oil heater is suitable for introducing oil, and the oil outlet of the oil heater is connected to the inlet of the oil inlet pipe to heat the oil and send it into the oil inlet pipe.
[0007] The outlet of the oil inlet pipe is connected to the inlet of the sampler, and the outlet of the sampler is connected to the inlet of the oil outlet pipe. The oil outlet pipe is suitable for conveying the sampled oil.
[0008] The oil inlet pipe is equipped with a filter, a pressure gauge, and a pump; the filter and pump are arranged sequentially along the flow direction of the oil in the oil inlet pipe.
[0009] The oil outlet pipe is equipped with a flow meter and a pressure transmitter; the flow meter and pressure transmitter are arranged sequentially along the flow direction of the oil in the oil outlet pipe.
[0010] In one possible implementation, a first shut-off valve is provided on the oil inlet pipe, and the first shut-off valve and the filter are arranged sequentially along the flow direction of the oil in the oil inlet pipe.

[0012] In one possible implementation, a differential pressure gauge is installed on the pressure bypass pipe.
[0013] In one possible implementation, the oil inlet pipe is equipped with a manual sampling pipe, which is connected to the oil inlet pipe.
[0014] In one possible implementation, a second shut-off valve is provided on the manual sampling pipeline.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.
[0031] like Figure 1 , Figure 2 As shown, a sampling device with oil heating function includes: an oil heater 800, an oil inlet pipe 100, an oil outlet pipe 200, and a sampler 500. The oil inlet of the oil heater 800 is used to introduce oil, and the oil outlet of the oil heater 800 is connected to the inlet of the oil inlet pipe 100 to heat the oil and send it into the oil inlet pipe 100. The outlet of the oil inlet pipe 100 is connected to the inlet of the sampler 500, and the outlet of the sampler 500 is connected to the oil outlet pipe 200. The inlet connection of 200 and the outlet pipe 200 are suitable for conveying the sampled oil. The inlet pipe 100 is equipped with a filter 400, a pressure gauge 120 and a pump 600. The filter 400, pressure gauge 120 and pump 600 are arranged in sequence along the flow direction of the oil in the inlet pipe 100. The outlet pipe 200 is equipped with a flow meter 210 and a pressure transmitter 240. The flow meter 210 and pressure transmitter 240 are arranged in sequence along the flow direction of the oil in the outlet pipe 200.
[0032] It should be noted that the oil heater 800 is used to heat the introduced oil, reduce its viscosity, and increase the flow rate of the oil in the inlet pipe 100 and outlet pipe 200. The inlet pipe 100 transports the oil to the sampler 500, and the outlet pipe 200 is used to send the oil out of the equipment. During this process, the sampler 500 samples the oil for subsequent analysis, detection, or testing. The filter 400 on the inlet pipe 100 is used to filter impurities inside the oil, ensuring that impurities do not enter the sampler 500 and affect its normal operation, thus ensuring its service life. The pump 600 is used to pressurize the oil, thereby providing power for the flow of the oil in the inlet pipe 100. This application integrates the oil heater 800 at the front end of the sampling structure, which reduces the viscosity of high-viscosity oil, increases the flow rate of oil, reduces the occurrence of wall adhesion, and ensures that the oil will not interfere with the normal sampling operation of the sampler 500. This significantly improves sampling efficiency and ensures that the sampled samples have good representativeness and accuracy.
[0033] In one possible implementation, a first shut-off valve 110 is provided on the oil inlet pipe, and the first shut-off valve 110 and the filter 400 are arranged sequentially along the flow direction of the oil in the oil inlet pipe 100. It should be noted that when sampling is not required, the first shut-off valve 110 must be closed to ensure that the oil does not flow in the oil inlet pipe 100.
[0034] In one possible implementation, it further includes a pressure-measuring bypass pipe 420, with both ends of the bypass pipe 420 connected to the front and rear ends of the filter 400, respectively. Furthermore, a differential pressure gauge 410 is installed on the pressure-measuring bypass pipe 420, with the probe of the differential pressure gauge 410 located inside the pressure-measuring bypass pipe 420. Figure 2 As shown, a connecting pipe is provided on the pipes at both ends of the filter 400, and a fifth shut-off valve 430 is provided on the connecting pipe. The two connecting pipes are respectively connected to the two ends of the pressure measuring bypass pipe 420. The differential pressure gauge 410 on the pressure measuring bypass pipe 420 is suitable for measuring the pressure difference of the oil before and after filtration.
[0035] Filter 400 uses a basket filter.
[0036] In one possible implementation, a pressure gauge 120 is provided on the inlet pipe 100 to detect the liquid pressure inside the inlet pipe 100 before sampling.
[0037] In one possible implementation, a check valve 610 is provided on the oil inlet pipe 100 to prevent backflow of oil at the downstream end; furthermore, the inlet and outlet ends of the check valve 610 are connected to the oil inlet pipe 100 by means of flange connection.
[0038] Furthermore, such as Figure 2 As shown, the first shut-off valve 110, filter 400, pressure gauge 120, pump 600, and check valve 610 are arranged in sequence along the flow direction of the oil in the oil inlet pipe 100.
[0039] In one possible implementation, such as Figure 2 As shown, the oil inlet pipe 100 is equipped with a manual sampling pipe 900, which is connected to the oil inlet pipe 100. Furthermore, the manual sampling pipe 900 is equipped with a second shut-off valve 910. The second shut-off valve 910 can control the opening and closing of the manual sampling pipe 900 at any time. By opening the second shut-off valve 910, oil flows out from the manual sampling pipe 900, enabling manual sampling. Manual sampling is used as a backup sampling method. When the sampler 500 is being maintained or cleaned, or when other special sampling requirements exist, the second shut-off valve 910 can be directly operated to perform manual sampling.
[0040] like Figure 2 As shown, the manual sampling pipe 900 is connected to the oil inlet pipe 100 via a tee 920, and the manual sampling pipe 900 and the oil inlet pipe 100 are interconnected by the tee. When manual sampling is required, the sample can be obtained from the manual sampling pipe 900 by opening the second shut-off valve 910 on the manual sampling pipe 900.
[0041] Furthermore, the sampler 500 adopts existing technology equipment, model number: ES11 Cell Sampler-0GM. A programmable logic controller (PLC) can be used to control the sampler 500. The PLC controls the drive mechanism of the sampler 500 according to the set parameters to realize the automatic sampling process.
[0042] In one possible implementation, the oil outlet pipe 200 is equipped with a densitometer 700, and the flow meter 210 and the densitometer 700 are arranged sequentially along the flow direction of the oil in the oil outlet pipe 200; preferably, the densitometer 700 is a double-tube vibrating densitometer.
[0043] In one possible implementation, the oil outlet pipe 200 is provided with a pressure relief pipe 230, which is connected to the oil outlet pipe 200, and a third shut-off valve 231 is provided on the pressure relief pipe 230. When the oil outlet pipe 200 is overpressurized, the pressure is released by opening the third shut-off valve 231.
[0044] In one possible implementation, the oil outlet pipe 200 is equipped with an exhaust pipe 220, which is located at the top of the oil outlet pipe 200 and connected to it. A sixth shut-off valve 221 is installed on the exhaust pipe 220, which is used to control the opening and closing of the exhaust pipe 220. Furthermore, the exhaust pipe 220 is connected to the oil outlet pipe 200 via a tee. It should be noted that when oil is first pumped or after pumping has stopped, residual gas may remain in the oil outlet pipe 200. Excessive gas can cause cavitation in the pump 600, easily damaging it. Therefore, the sixth shut-off valve 221 needs to be opened to allow the gas to be discharged from the oil outlet pipe 200 before restarting the pump.
[0045] In one possible implementation, the oil outlet pipe 200 is equipped with a pressure transmitter 240, and the flow meter 210, density meter 700, and pressure transmitter 240 are arranged in sequence along the flow direction of the oil in the oil outlet pipe 200; the pressure transmitter 240 is suitable for detecting the liquid pressure of the oil in the oil outlet pipe 200 after sampling.
[0046] In one possible implementation, the oil outlet pipe 200 is equipped with a seventh shut-off valve 250. The flow meter 210, density meter 700, pressure transmitter 240 and the seventh shut-off valve 250 are arranged sequentially along the flow direction of the oil in the oil outlet pipe 200.
[0047] In one possible implementation, it further includes: a drain pipe 300, one end of which is connected to the drain port of the filter 400, and the other end of which is adapted to discharge sludge and oil. Figure 1 The main body of the sewage pipe 300 is a U-shaped tubular structure.
[0048] Furthermore, the sewage pipe 300 is equipped with an eighth shut-off valve 310, which is suitable for controlling the opening and closing of the sewage pipe.
[0049] In one possible implementation, the oil outlet pipe 200 is equipped with a discharge pipe 320. One end of the discharge pipe 320 is connected to the oil outlet pipe 200, and the other end is connected to the sewage pipe 300. A fourth shut-off valve 321 is provided on the discharge pipe 320 to control its opening and closing at any time. When the equipment stops working, the residual oil in the oil outlet pipe 200 needs to flow to the outside through the discharge pipe 320. Furthermore, the pressure relief pipe 230 and the discharge pipe 320 are connected to the oil outlet pipe 200 via a four-way pipe fitting 232.
[0050] In one possible implementation, a sample storage container 510 is also included, with the sample outlet of the sampler 500 connected to the inlet of the sample storage container 510 via a pipe. The sample storage container 510 is suitable for storing samples.
[0051] The oil heater 800 is suitable for reducing the viscosity of oil to the range where the sampler 500 can operate normally (typically 5-50 cst).
[0052] In one possible implementation, the oil heater 800 may be a pipe heater.
[0053] In another possible implementation, the oil heater 800 can also be an electric heater; when the oil heater 800 is an electric heater, the formula for calculating the electric heater power required to heat the oil to the target viscosity is as follows:
[0054]
[0055] Where: P is the power of the electric heater (kW), Q is the heat required to heat the oil (kJ), t is the heating time (s), m is the oil mass flow rate (kg / s), and c p ΔT is the specific heat capacity of the oil (kJ / (kg·℃)), ΔT is the temperature change of the oil (℃), and η is the efficiency of the electric heater (generally taken as 0.85-0.95).
[0056] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
