Description

Technical Field

[0001] This utility model relates to the field of oil and water, and in particular to an online analysis, identification, acquisition, and data processing device for oil-water interfaces. Background Technology

[0002] Oil-water interface measurement is used in almost every aspect of production and daily life. For example, ships need to monitor and control cargo oil, sewage, ballast water, and fuel oil through tank level measurement; oil refineries and chemical plants need to obtain information about the oil-water interface in storage tanks through level measurement systems in order to implement further integrated control and management. Therefore, the rapid and accurate determination of the location of the oil-water interface has significant application value.

[0003] Currently, commonly used metrology technologies and instrument types on the market include buoyancy-based, capacitive, pressure-based, ultrasonic, and radar-based interface detection. Float-based oil-water interface detection is simple and easy to implement, and has a certain level of accuracy. However, it is relatively difficult to maintain for large oil tanks. Capacitive oil-water interface detection methods have high sensitivity, good dynamic response characteristics, and good anti-interference performance of the capacitance test conversion circuit. However, the measurement accuracy is affected by humidity and pressure, and the price is relatively high among domestic instruments. Differential pressure oil-water interface detectors are installed entirely outside the tank, making maintenance relatively easy, but this method is prone to clogging pipelines, requiring regular drainage, and the measurement accuracy is affected by liquid density. Radar / ultrasonic oil-water interface detectors are suitable for various liquids (such as high-viscosity liquids, where the surface or interface only needs to be horizontal), channels, and open / closed containers, and are less prone to adhesion, cleaning, and leakage problems. However, the measurement accuracy of this detection method is easily affected by the pressure, humidity, and temperature inside the container, and the container is not easy to carry, and the installation of components presents certain difficulties.

[0004] For example, in the patented device and method for detecting the oil-water interface (CN103344300A), the device includes a signal acquisition card, a signal differential amplifier, a microprocessor, a micro motor, a detection electrode, an electrode protective cover, an operating switch, a display, an alarm, a portable handle, and a protective shell. The detection electrode is placed inside the electrode protective cover and is connected to the micro motor via a flexible wire, with the micro motor controlling the descent speed of the detection electrode. The detection electrode is connected to the signal acquisition card via a flexible data cable, bypassing the micro motor. The signal acquisition card is connected to the signal differential amplifier and then to the input port of the microprocessor, which has built-in signal acquisition, filtering, time recording, and data processing programs. This invention is based on the principle of electrostatic induction, and its measurement accuracy is not affected by factors such as viscosity, density, and pressure. It exhibits good detection and measurement stability, and has high detection sensitivity and accuracy.

[0005] The aforementioned patent utilizes the principle of electrostatic induction to achieve good stability in detection and measurement, exhibiting high detection sensitivity and accuracy. However, in daily use, because the device relies on the resistance change of electrodes in oil and water to detect the water depth on the oil surface within the device, other data contained in the oil and water cannot be monitored, thus narrowing the device's applicability. Therefore, it is necessary to invent an online oil-water interface analysis, identification, acquisition, and data processing device to solve the above problems. Utility Model Content

The activated carbon layer can filter impurities in the gas guide pipe, thereby avoiding damage to the monitoring equipment by impurities. The overflow valve connected to the liquid inlet and liquid outlet can release the gas when the gas pressure in the device is too high, thereby improving the safety of the device and improving its practicality.
