Description

Technical Field

[0001] This utility model relates to the field of petroleum engineering technology, and in particular to a multi-stage concentration and purification device for fracturing tracers. Background Technology

[0002] In oil and gas field fracturing, tracers are used to help monitor the flow path of fracturing fluid and the propagation of fractures. By adding tracers to the fracturing fluid, the distribution of the fracturing fluid can be tracked in real time, the fracturing effect can be judged, and operating parameters can be optimized. A multi-stage concentration and purification device for fracturing tracers can concentrate and purify the tracers in multiple stages, ensuring the high efficiency and accuracy of the tracers, thereby enabling them to play a better role in oil and gas field fracturing.

[0003] The structure of a multi-stage concentration and purification device for fracturing tracers includes a filter plate one, a rotating plate, a filter plate two, etc. The multi-stage concentration and purification device for fracturing tracers gradually increases the concentration and purity of the tracer through multiple steps. Large particulate impurities are removed through pretreatment, and then concentration and purification are achieved through technologies such as evaporation, membrane separation, adsorption, and crystallization.

[0004] In existing technologies, some multi-stage concentration and purification devices for fracturing tracers use fixed filter plates for single-stage filtration. This often results in filtration efficiency and precision that cannot meet the requirements of multiple high-efficiency filtrations. A single filtration process cannot completely remove all fine impurities. In particular, when the liquid contains extremely fine particles, the pores of the filter plate are easily clogged, thereby reducing the filtration effect. To address these issues, a multi-stage concentration and purification device for fracturing tracers is proposed. Utility Model Content

[0034] A connecting rod 12 is fixedly connected inside the rotating plate 11. A filter plate 13 is fixedly connected to the inner side of the connecting rod 12. The filter plate 13 is slidably connected inside the filter box 2. The filter plate 13 is the actual filtration part.

The elastic assembly includes multiple connecting blocks 14 and multiple elastic plates 15. The multiple connecting blocks 14 are externally fixedly connected inside the filter box 2.

[0036] Working principle: The liquid enters the feed pipe 6 through the feeding funnel 5 in the support frame 4 and is evenly introduced into the filter box 2 for preliminary treatment. The filter mechanism 3 in the filter box 2 is responsible for fine filtration of the raw materials. The motor 7 is driven by the output shaft 8, which drives the rotating circular plate 9 to rotate, thereby driving the rotation of the connecting shaft 10 and the rotating plate 11 connected to the front. The connecting shaft 10 is connected to the side of the rotating circular plate 9 to achieve the eccentric rotation effect. The movement of the rotating plate 11 causes the filter plate 13 connected to the connecting rod 12 to vibrate. The elastic plate 15 connected to the connecting block 14 provides elastic support and keeps the filter plate 13 stable during vibration. The vibration of the filter plate 13 enhances the filtration process of the material, ensures that the filter medium is not easily blocked, and improves the filtration efficiency. During the filtration process, the filter plate 16 completes secondary filtration. The impurities that cannot be filtered settle at the bottom of the filter box 2. After two stages of filtration, the liquid in the filter box 2 flows out through the output pipe 17 and enters the concentration and purification tank 19.

[0037] In the concentration and purification tank 19 of the steam utilization mechanism 18, the water in the liquid is evaporated, and the steam is guided into the tank through the conical guide top cover 21. The thermal efficiency is improved by heating. During the concentration process, the excess steam is introduced into the water tank 23 for recovery through the steam inflow pipe 22. The concentrated material is discharged through the discharge pipe 20 of the concentration and purification tank 19 and enters the next processing step.
