Description

Technical Field

[0001] This invention relates to the field of pipeline descaling technology, specifically to a distributed ultrasonic long pipeline descaling system and method. Background Technology

[0002] Pipeline scaling is a common problem in industrial production and civil facilities. Traditional descaling methods, such as chemical cleaning and mechanical scraping, are inefficient, costly, and cause environmental pollution. Ultrasonic descaling technology, due to its non-invasive and environmentally friendly advantages, is widely used in pipeline maintenance.

[0003] Ultrasonic descaling technology relies on piezoelectric ceramic units, which are fixed to the pipeline to generate ultrasonic waves for descaling. However, for descaling long pipelines, multiple piezoelectric ceramic units are required. It is difficult to adjust the operating parameters of the piezoelectric ceramic units according to the descaling effect. Furthermore, when a standing wave is generated at a certain point in the pipeline, the piezoelectric ceramic units need to be disassembled and moved to adjust their positions, resulting in low descaling efficiency for long pipelines.

[0072] Example 1

[0073] This embodiment provides a distributed ultrasonic descaling method for long pipelines, such as... Figure 1 As shown, it includes the following steps:

[0074] S1, A ring-shaped piezoelectric ceramic array is set on the pipe;

[0075] S2, An amplitude sensor is placed between the ring-shaped piezoelectric ceramic array;

[0076] S3, set the piezoelectric ceramic strength, piezoelectric ceramic frequency and piezoelectric ceramic phase, and start the ring piezoelectric ceramic array;

[0077] S4, calculates the pipeline vibration intensity in real time based on the amplitude sensor;

[0078] S5. Based on the pipeline vibration intensity, the piezoelectric ceramic phase is optimized using an optimization algorithm to obtain the optimal piezoelectric ceramic phase.

[0079] S6, update the piezoelectric ceramic phase according to the optimal piezoelectric ceramic phase to descale the pipeline.

[0080] It should be noted that the annular piezoelectric ceramic array module consists of multiple piezoelectric ceramic units, which are fitted onto the outer wall of the pipe to achieve full circumferential coverage. The number, deployment location, and deployment distance of the annular piezoelectric ceramic arrays are not limited and can be randomly set or determined based on experience. The amplitude sensor is a triaxial amplitude sensor, which is clamped between two adjacent annular piezoelectric ceramic arrays. The piezoelectric ceramic intensity, piezoelectric ceramic frequency, and piezoelectric ceramic phase are used to control the output amplitude and frequency of the ultrasonic waves generated by the annular piezoelectric ceramic array. The annular piezoelectric ceramic array is activated, and the vibration intensity of the pipe is obtained through the amplitude sensor. The pipe vibration intensity reflects the intensity of pipe descaling; therefore, the piezoelectric ceramic phase is optimized based on the pipe vibration intensity to improve pipe descaling efficiency.

[0081] In this embodiment, by setting an annular piezoelectric ceramic array on the pipeline and placing amplitude sensors between the annular piezoelectric ceramic arrays, the pipeline vibration intensity is acquired in real time. The phase of the annular piezoelectric ceramic array is optimized and adjusted according to the pipeline vibration intensity to ensure that descaling is performed in the best working state. At the same time, it avoids the disassembly and movement of multiple piezoelectric ceramic units, thus improving the descaling efficiency of long pipelines.

[0082] In some embodiments, step S4 involves calculating the pipe vibration intensity in real time based on the amplitude sensor, such as... Figure 2 As shown, it includes the following steps:

[0083] S41, set the amplitude sampling frequency according to the piezoelectric ceramic frequency;

[0084] S42, obtain the triaxial amplitude of the pipeline based on the amplitude sensor and amplitude sampling frequency;

[0085] S43, Calculate the vibration energy of the pipeline based on the triaxial amplitude of the pipeline;

[0086] S44, calculate the pipeline vibration intensity based on the pipeline vibration energy and the number of amplitude sensors.

[0087] In some embodiments, the formula for calculating pipeline vibration energy is as follows;

[0088] ,

[0089] in, For pipeline vibration energy, The amplitude sampling frequency, The x-axis amplitude of the pipeline. The amplitude of the pipe's y-axis is... The amplitude of the pipe's z-axis.

[0090] The formula for calculating pipeline vibration intensity is as follows:

[0091] ,

[0092] in, For pipeline vibration intensity, For the number of amplitude sensors, For the first The weighting coefficients of each amplitude sensor, According to the first The vibration energy of the pipeline is calculated by an amplitude sensor.

[0093] It should be noted that the amplitude sampling frequency is used to control the sampling interval of the amplitude sensor. According to existing technology, the amplitude sampling frequency is set to twice the piezoelectric ceramic frequency. By setting the sampling frequency, the triaxial amplitude of the pipeline is obtained, that is, the vibration amplitude of the pipeline in three mutually perpendicular directions, usually denoted as x-axis amplitude, y-axis amplitude, and z-axis amplitude, and the pipeline vibration energy is calculated accordingly. The pipeline vibration intensity is obtained by weighted summation of the pipeline vibration energy calculated by each amplitude sensor, and the weighting coefficient of each amplitude sensor is initialized to 1.

[0094] In this embodiment, the triaxial amplitude of the pipeline is obtained by an amplitude sensor, the vibration energy of the pipeline is calculated, and the vibration energy of the pipeline is weighted and summed to obtain the vibration intensity of the pipeline. This provides a data basis for the optimization of the piezoelectric ceramic phase and improves the descaling efficiency of long pipelines.

[0095] In some embodiments, step S5 involves optimizing the piezoelectric ceramic phase using an optimization algorithm based on the pipeline vibration intensity to obtain the optimal piezoelectric ceramic phase, such as... Figure 3 As shown, it includes the following steps:

[0096] S51, construct the fitness function based on the pipeline vibration intensity;

[0097] S52 uses the piezoelectric ceramic phase as the particle position;

[0098] S53 updates the piezoelectric ceramic phase based on the particle position and calculates the fitness value in real time;

[0099] S54, based on the fitness value, update the optimal fitness value and the optimal particle position;

[0100] S55, update particle velocity and particle position based on the optimal fitness value;

[0101] S56, repeatedly update particle velocity and particle position until the maximum number of iterations is reached;

[0102] S57 outputs the optimal particle position, thus obtaining the optimal piezoelectric ceramic phase.

[0103] The formula for calculating fitness value is as follows:

[0104] ,

[0105] in, For fitness value, For pipeline vibration intensity, For the number of amplitude sensors, For the first The weighting coefficients of each amplitude sensor, According to the first The vibration energy of the pipeline is calculated by an amplitude sensor.

[0106] It should be noted that the optimization of the piezoelectric ceramic phase combines particle swarm optimization (PSO) with real-time data acquisition. Specifically, to improve the descaling effect on pipelines, the goal is to maximize pipeline vibration intensity; therefore, the logarithm of the pipeline vibration intensity is used as the fitness function. The initial value of the piezoelectric ceramic phase is 0. The piezoelectric ceramic phase is used as the particle position in the particle swarm. By updating the piezoelectric ceramic phase, the phase of the ring piezoelectric ceramic array is adjusted in real time, and the pipeline vibration energy is acquired to calculate the pipeline vibration intensity. This process of updating the piezoelectric ceramic phase and calculating the pipeline vibration intensity is repeated, updating the optimal fitness value and the optimal particle position until the maximum number of iterations is reached. The iterative update process is essentially the same as that of the PSO algorithm and will not be elaborated here. Finally, after the iteration is complete, the optimal fitness value output is the maximum pipeline vibration intensity, and the optimal particle position is the optimal phase of the ring piezoelectric ceramic array.

[0107] In this embodiment, by combining particle swarm optimization algorithm with real-time data acquisition, the phase of the piezoelectric ceramic is iteratively updated, the working phase of the annular piezoelectric ceramic array is adjusted in real time, and the vibration energy of the pipeline is calculated, thereby obtaining the optimal piezoelectric ceramic phase and improving the descaling efficiency of long pipelines.

[0108] In some embodiments, after step S6, which involves updating the piezoelectric ceramic phase according to the optimal piezoelectric ceramic phase to descale the pipeline, the following steps are also included:

[0109] S7, obtain the inlet velocity and outlet velocity of the pipe;

[0110] S8, Calculate the pipe velocity ratio based on the pipe inlet velocity and the pipe outlet velocity;

[0111] S9 controls the operating state of the annular piezoelectric ceramic array based on the flow rate ratio in the pipeline.

[0112] It should be noted that after obtaining the optimal piezoelectric ceramic phase, the phase is adjusted to the optimal piezoelectric phase, and descaling of the pipeline is performed under this optimal phase and a preset working time. However, the cleaning difficulty of scale varies at different locations in a long pipeline. While optimizing the piezoelectric ceramic phase considers the overall optimal descaling effect, after the descaling time has elapsed, some areas of the pipeline may exhibit lower cleaning efficiency. Furthermore, the optimization of the piezoelectric ceramic phase only uses a single particle update iteration, which, due to limitations in population size and iteration count, will result in certain limitations in the optimization results. Therefore, flow velocity sensors are connected in series at both ends of the pipeline to obtain the inlet and outlet flow velocities, calculate the pipeline flow velocity ratio, and adjust the operating parameters of the annular piezoelectric ceramic array accordingly.

[0113] In this embodiment, by obtaining the inlet and outlet flow velocities of the pipeline, the pipeline flow velocity ratio is calculated, and the working state of the annular piezoelectric ceramic array is optimized a second time based on the pipeline flow velocity ratio, thereby improving the descaling efficiency of long pipelines.

[0114] In some embodiments, step S9 involves controlling the operating state of the annular piezoelectric ceramic array according to the pipe flow rate ratio, such as... Figure 4 As shown, it includes the following steps:

[0115] S91, Set the descaling threshold and compare the pipeline flow rate ratio with the descaling threshold;

[0116] S92, when the pipeline flow rate ratio is greater than or equal to the descaling threshold, the real-time data is uploaded to the cloud for storage and the ring piezoelectric ceramic array is stopped;

[0117] S93, when the pipeline flow rate ratio is less than the descaling threshold, the piezoelectric ceramic phase is repeatedly optimized.

[0118] The formula for calculating the flow velocity ratio in a pipe is as follows:

[0119] ,

[0120] in, The flow velocity ratio in the pipeline. The inlet velocity of the pipe is... The outlet velocity of the pipeline.

[0121] It should be noted that the descaling threshold is used to evaluate the descaling status of the pipeline. In some preferred embodiments, the descaling threshold is set to 0.9. When the pipeline flow rate ratio is greater than or equal to the descaling threshold, it indicates that the descaling effect meets expectations. The real-time collected data and optimization process data are uploaded to the cloud platform for storage as historical descaling records or for generating descaling reports. When the pipeline flow rate ratio is less than the descaling threshold, it indicates that the descaling effect does not meet expectations, and secondary optimization of the piezoelectric ceramic phase is required to continue pipeline descaling.

[0122] In some embodiments, in step S93, when the pipeline flow rate ratio is less than the descaling threshold, the piezoelectric ceramic phase is repeatedly optimized, such as... Figure 5 As shown, it includes the following steps:

[0123] S931, based on the optimal piezoelectric ceramic phase, obtain the optimal triaxial amplitude of the pipeline;

[0124] S932, calculate the optimal pipeline vibration energy based on the optimal triaxial amplitude of the pipeline;

[0125] S933 optimizes the weighting coefficients of the amplitude sensor based on the optimal pipeline vibration energy;

[0126] S934 initializes the piezoelectric ceramic phase and optimizes the piezoelectric ceramic phase;

[0127] The optimized formula for the weighting coefficients of the amplitude sensor is expressed as follows:

[0128] ,

[0129] in, For the first The weighting coefficients of each amplitude sensor, According to the first The optimal pipeline vibration energy is calculated by an amplitude sensor.

[0130] It should be noted that, considering the varying cleaning difficulty of scale buildup at different locations within long pipelines, the optimization of the piezoelectric ceramic phase aims for optimal overall descaling performance. However, after a period of operation, some pipeline areas may exhibit lower descaling efficiency. Therefore, the weighting coefficients of the amplitude sensor are optimized by calculating the pipeline vibration energy under the optimal piezoelectric ceramic phase. After optimizing the weighting coefficients of the amplitude sensor, steps S51 to S57 are repeated to further optimize the piezoelectric ceramic phase.

Figure 6 As shown, it includes: a ring piezoelectric ceramic array module, an amplitude sensor module, an edge computing module, and a phase synchronization module;

[0133] A ring-shaped piezoelectric ceramic array module is used to install on pipes, setting the piezoelectric ceramic strength, frequency, and phase to descale the pipes;

[0134] An amplitude sensor module is used to be placed between the ring piezoelectric ceramic array modules to calculate the vibration intensity of the pipeline in real time.

[0135] The edge computing module is used to optimize the piezoelectric ceramic phase based on the pipeline vibration intensity using an optimization algorithm to obtain the optimal piezoelectric ceramic phase.

[0136] The phase synchronization module is used to update the piezoelectric ceramic phase according to the optimal piezoelectric ceramic phase to descale the pipeline.

[0137] In this embodiment, by setting an annular piezoelectric ceramic array on the pipeline and placing amplitude sensors between the annular piezoelectric ceramic arrays, the pipeline vibration intensity is acquired in real time. The phase of the annular piezoelectric ceramic array is optimized and adjusted according to the pipeline vibration intensity to ensure that descaling is performed in the best working state.
