Four ultrasonic transducers and a trapezoidal module with an inclined angle are combined, and the trapezoidal module and the pipeline are combined in a curvature mode.

The trapezoidal module can provide a certain inclination angle, so that ultrasonic body waves emitted by the ultrasonic transducer are converted into ultrasonic guided waves, and the pipeline cleaning length of the ultrasonic descaling device is increased.

Description

Technical Field

[0001] The invention belongs to the field of ultrasonic transducer and pipeline combination structure, and specifically relates to an ultrasonic descaling device. Background Art

[0002] Oil is one of the most important energy sources in the world and is widely used in various fields of industry, transportation and life. In order to meet people's demand for oil, oil needs to be transported from the production site to various processing plants through pipelines to further serve people's lives. Therefore, the safety, efficiency and economy of oil pipeline transportation are crucial to ensuring energy supply and maintaining economic development.

[0003] In pipeline transportation, pipeline dirt will deteriorate the oil transportation conditions, and it is easy to be adsorbed and accumulated on the bends and pipeline walls. The scale samples collected from the pipeline include various inorganic substances and organic substances mainly composed of petroleum and asphalt. Among them, inorganic scale is the most typical, collectively referred to as oilfield scale. The oilfield scale that appears in large quantities in the pipeline can be roughly divided into salt scale, corrosion scale, sediment and other sediment scales in terms of composition. Scale is easy to accumulate inside the pipeline during long-term use, resulting in a reduction in the effective cross-sectional area of ​​the pipeline, hindering pipeline oil transportation, polluting the transported liquid, corroding the pipeline wall, and even threatening people's lives. Therefore, the solution for oil pipeline descaling and anti-scaling is particularly important.

[0004] As a new type of environmentally friendly acoustic application that meets the needs of domestic and international industrial development, ultrasonic pipeline scale removal and prevention technology can not only actively respond to the country's policies on sustainable and green development and the construction of a modern oil and gas pipeline network, but also minimize energy loss through the characteristics of the propagation of pulse elastic ultrasound in metals, making scale removal and prevention efficient, making an important contribution to pipeline scale removal and prevention.

[0005] However, in the process of using ultrasonic pipeline descaling and anti-scaling technology, there are problems with the combination structure of the ultrasonic descaling device and the pipeline. Traditional ultrasonic descaling only uses an ultrasonic transducer to directly combine with the pipeline by welding. During the operation, there will be problems such as the ultrasonic transducer falling off due to long-term work, inconvenient equipment replacement and maintenance, and low work efficiency. These problems need to be solved urgently. Therefore, it is necessary to design a new combination structure to optimize the ultrasonic pipeline descaling and anti-scaling technology. Summary of the invention

[0006] In view of this, the ultrasonic descaling system and pipeline combination structure based on ultrasonic descaling technology provide a solution to the above-mentioned shortcomings of traditional ultrasonic descaling methods.

[0007] To achieve the above object, the technical solution of the present invention is as follows.

[0008] The present invention mainly provides a new ultrasonic transducer array design and a combination structure with a pipeline. It is composed of four ultrasonic transducers and a trapezoidal module with an inclination angle, and the trapezoidal module and the pipeline are combined with curvature. The trapezoidal module and the ultrasonic transducer are linked by spiral bite, which can avoid the loss of the transducer caused by the welding of the ultrasonic transducer and the pipeline, as well as the problem of falling off after long-term work and is easy to replace. The trapezoidal module can provide a certain inclination angle to convert ultrasonic body waves into ultrasonic guided waves, thereby increasing the length of the pipeline cleaned by the ultrasonic descaling device.

[0009] Furthermore, the upper base of the trapezoidal module cross section is 100 mm, and the lower base conforms to the curvature of the pipeline so that it is tightly integrated with the pipeline; its height is 100 mm, thickness is 200 mm, and the angle between the hypotenuse and the bottom edge is 45°.

[0010] Furthermore, the maximum ultrasonic output power of the ultrasonic transducer is 100 kW, the ultrasonic duty cycle is 50%, and the frequency is 28 kHz.

[0011] Furthermore, the structure is composed of four ultrasonic transducers and a trapezoidal module with an inclined angle, which are respectively located at the top, bottom, left and right of the pipeline. The ultrasonic descaling device and the pipeline are combined in such a way that the trapezoidal module is welded to the pipeline; the ultrasonic transducer and the trapezoidal module are screwed together; the four devices are combined together through a chain structure and each unit has the same structure and is fixed with a bolt pin; the entire module is made of titanium alloy.

[0012] Compared with the existing traditional technology, the novel ultrasonic descaling device combined with the pipeline structure described in the present invention has the following advantages.

[0013] Compared with the direct welding of the ultrasonic transducer to the pipeline, the present invention innovatively establishes a trapezoidal module to be combined with the pipeline and the ultrasonic transducer and the trapezoidal module are linked by spiral engagement, which solves the problem of the ultrasonic transducer falling off the pipeline during operation and converts the ultrasonic body waves generated by the ultrasonic transducer into ultrasonic guided waves through the trapezoidal module, further increasing the length of the pipeline where the equipment acts and enhancing its descaling length and effect.

[0014] Compared with the ultrasonic transducer acting on the pipeline alone, the present invention proposes a method of arranging four ultrasonic transducers in a surrounding array design, which further improves the efficiency and intensity of ultrasonic transducer descaling, and ultimately significantly enhances the effect of ultrasonic descaling.
