Description

Technical Field

[0001] The invention relates to the technical field of water content detection, and in particular to an online rapid detection device for the water content of crude oil. Background Art

[0002] The pre-treated crude oil can remove impurities. At the same time, in order to ensure that the crude oil has high fluidity, the crude oil needs to be heated to a high temperature so that the crude oil can flow quickly. During the transportation of liquid crude oil, an online rapid detection device for the water content of crude oil needs to be used to monitor the water content in the crude oil in real time, so as to obtain the water content data of the crude oil and facilitate the subsequent treatment of the crude oil liquid.

[0003] CN116008310A discloses a quick-install online crude oil water content detection device and its installation method. The detection device is equipped with a microwave detection antenna and a PCB board connected to the microwave detection antenna on the side of a liquid contact structure. A central hole is provided in the center of the liquid contact structure for the crude oil in the pipeline to flow through, and a groove is opened in the hole wall of the central hole to expose part of the microwave detection antenna to detect the water content of the crude oil. During installation, the sealing steel ring in the original clamp is replaced with the water content sensor of the device, and an external explosion-proof meter head is installed. Although the detection device greatly simplifies the installation of the water content detection device on the wellhead pipeline of the oil and gas well, it has the following problems: When the detection device detects the water content of crude oil liquid online, since the crude oil liquid flows in a vertical section at the pipeline position and has a large flow surface, and the water content sensor of the detection device is at a fixed position during detection, it is difficult to quickly detect the water content of a large area of ​​crude oil liquid at multiple precise points on the periphery, and it is difficult to quickly detect the water content of the crude oil liquid at multiple precise points on the inner periphery simultaneously. At the same time, it is difficult to know the position data of the specific detection points. The specific position of the water content needs to be analyzed later, resulting in a slow detection speed of the water content of the crude oil liquid at multiple points online, and thus a low detection efficiency of the water content of the crude oil liquid.

[0011] 2. A peripheral position linkage detection mechanism is adopted. When the guide rod moves down in a rightward arc, the guide rod will drive the connecting bar to move down in a rightward arc, and the first reading sensor moves down in a rightward arc along the inner wall of the groove ring, and the first reading sensor moves down in a rightward arc along the inner wall of the slide groove.

[0032] The working principle of the online rapid detection device for the water content of crude oil of the present invention is as follows: First, when the present invention is docked and installed, angle values ​​and specific height values ​​are read and written on multiple peripheral identification barcodes 25, respectively, and specific position information can be read and written on multiple peripheral identification barcodes 25. At the same time, specific horizontal values ​​are read and written on multiple inner peripheral identification barcodes 36. The docking plate 17 is docked to the crude oil liquid delivery pipeline by bolts, and the crude oil liquid will be pressurized and heated during the delivery process, so the crude oil liquid has a higher fluidity, and another docking plate 17 is docked to another crude oil liquid delivery pipeline, and the crude oil liquid delivery flow operation is formed through the detection channel 1.

[0033] Secondly, when the present invention performs peripheral multi-point detection, the reduction motor 5 is started through the wireless controller 15, the reduction motor 5 drives the screw 4 to rotate forward, the detection channel 1 supports the shell 2, and the detection channel 1 supports the support frame 3. The screw 4 drives the sleeve block 6 to move downward under the action of the thread transmission force, and the sleeve block 6 drives the linkage column 7 to move downward. The linkage column 7 slides down along the inner wall of the sealing shaft ring 20. At the same time, the sealing shaft ring 20 realizes a sealing operation on the outer wall of the linkage column 7, and the linkage column 7 drives the guide frame 8 to move downward.

[0034] At the same time, the guide frame 8 drives the two sliding shafts 9 to move downward, and the sliding shaft 9 moves rightward on the inner wall of the guide frame 8, and the other sliding shaft 9 moves leftward on the inner wall of the guide frame 8, so that the sliding shaft 9 drives the two limit rings 13 to slide rightward on the guide frame 8. The sliding shaft 9 drives the peripheral water content sensor 10 to slide rightward, and the other peripheral water content sensor 10 to slide leftward, and the sliding shaft 9 drives the guide rod 11 to move down in a rightward arc along the inner wall of the circular track 12. At the same time, the detection channel 1 supports the support plate 22, and the support plate 22 supports the support block 21. The support block 21 provides a stable supporting force for the circular track 12, and the other guide rod 11 moves down in a leftward arc along the inner wall of the circular track 12. The guide rod 11 drives the two slip rings 14 to move down in a rightward arc, and the sliding shaft 9 drives the peripheral water content sensor 10 to move down in a rightward arc, and the other peripheral water content sensor 10 moves down in a leftward arc. The two peripheral water content sensors 10 can detect the water content of crude oil liquid at multiple points inside and outside the detection channel 1 to achieve rapid mobile detection.

[0035] Then the induction block 18 will approach the vertical distance sensor 19. When the distance value sensed by the vertical distance sensor 19 is the displacement value set by the wireless controller 15, the reduction motor 5 is started through the wireless controller 15. The reduction motor 5 drives the screw 4 to reverse. The screw 4 drives the sleeve block 6 to move up under the action of the thread transmission force. The sleeve block 6 drives the linkage column 7 to move the guide frame 8 up. The guide frame 8 drives the sliding shaft 9 to move up. The sleeve block 6 drives the linkage column 7 to move the guide frame 8 up. The guide frame 8 drives the two sliding shafts 9 to move up in an arc. The sliding shaft 9 drives the right guide rod 11 to move up in an arc. The sliding shaft 9 drives the peripheral water content sensor 10 to move up in a right arc. Another peripheral water content sensor 10 can also move up in a left arc. The two peripheral water content sensors 10 can realize peripheral multi-point detection of crude oil liquid inside the detection channel 1.

[0036] At the same time, when the present invention performs peripheral position linkage detection, when the guide rod 11 moves down in a rightward arc, the guide rod 11 will drive the connecting bar 23 to move down in a rightward arc, and the connecting bar 23 will drive the first reading sensor 24 to move down in a rightward arc, and the first reading sensor 24 will move down in a rightward arc along the inner wall of the groove ring 26, and the first reading sensor 24 will move down in a rightward arc along the inner wall of the slide groove 28. At the same time, the detection channel 1 supports the reinforcement block 27, and the reinforcement block 27 supports the groove ring 26, and the groove ring 26 can provide support for multiple peripheral identification barcodes 25. At the same time, the first reading sensor 24 will move down in a rightward arc along multiple peripheral identification barcodes 25, and another first reading sensor 24 will move down in a leftward arc along other peripheral identification barcodes 25, and the first reading sensor 24 will read data from multiple peripheral identification barcodes 25. When the first reading sensor 24 moves to the position of the peripheral identification barcode 25, the height value and the angle value of the peripheral identification barcode 25 are read, so that the water content value sensed by the peripheral water content sensor 10 corresponding to the peripheral identification barcode 25 here is known. In this way, the petroleum liquid water content values ​​corresponding to the specific positions of multiple points in the periphery can be known, and the water content detection of multiple points in the periphery can be quickly and accurately realized.

[0037] At the same time, when the present invention performs synchronous detection of multiple points in the inner periphery, when the guide frame 8 moves downward, it will drive the connecting block 37 to move downward, the connecting block 37 will drive the transverse frame 34 to move downward, the transverse frame 34 will cause the guide column 33 to move downward, and the guide column 33 will drive the second reading sensor 35 to move downward. At the same time, the guide column 33 drives the sleeve rod 30 to move downward, and the sleeve rod 30 causes the two sliding limit rings 31 to move downward. The sliding limit ring 31 will slide up and down the S-shaped track 29, and at the same time, the sleeve rod 30 moves downward in an S-shaped path along the inner wall of the S-shaped track 29, and the sleeve rod 30 slides laterally along the outer wall of the guide column 33, and the sleeve rod 30 will drive the inner periphery moisture content sensor 32 to move downward along the S-shaped path. The sleeve rod 30 will also drive the second reading sensor 35 to move at the bottom of multiple inner periphery identification barcodes 36. When the second reading sensor 35 approaches the inner periphery identification barcode 36 at the specified position, it is recognized by the inner periphery identification barcode 36 to identify the lateral position at this time. At the same time, the vertical distance sensor 19 performs distance sensing on the sensing block 18, and the vertical height position of the inner periphery identification barcode 36 at this time can be known.

[0038] When the guide frame 8 drives the connecting block 37 to move upward, the connecting block 37 will drive the transverse frame 34 to move upward, and the transverse frame 34 causes the guide column 33 to move upward, and the guide column 33 drives the sleeve rod 30 to move upward along the S-shaped path, and the inner water content sensor 32 moves upward along the S-shaped path, and the sleeve rod 30 drives the second reading sensor 35 to continue to move the transverse position, so that the transverse position is continuously identified by the inner identification barcode 36, and the distance sensing of the sensing block 18 is performed by the vertical distance sensor 19, so that the inner water content sensor 32 can realize vertical reciprocating movement along the S-shaped path to detect the water content of the crude oil liquid, so that the water content detection of multiple points in the inner periphery can be quickly and accurately realized.

[0039] Finally, when the present invention performs online detection, the crude oil liquid water content values ​​detected by the inner water content sensor 32 and the two outer water content sensors 10 are displayed on the display screen 16 on the wireless controller 15. At the same time, the wireless controller 15 can remotely transmit the data online to the background monitoring computer, and the background monitoring personnel can know the water content values ​​of multiple precise locations online in real time.
