Description

Technical Field

[0001] The present invention relates to the technical field of high - speed mixed - bed water distribution plate detection, and particularly to a method and system for detecting and grading the damage of a high - speed mixed - bed water distribution plate. Background Art

[0002] A high - speed mixed bed is a desalination device in the condensate polishing system of a power plant. Among them, the water distribution plate is an important component of the high - speed mixed bed, which plays a role in evenly distributing water and improving water production efficiency. However, since the water flow velocity in the high - speed mixed bed during operation can reach 100 - 130 m / h, with the passage of time and the influence of other factors, the water distribution plate may be damaged, affecting its performance and working efficiency. In the condensate polishing system of a power plant, due to the rapid fluctuation of the unit load, the instantaneous changes in the flow rate and pressure of the high - speed mixed bed impact the perforated plate, causing the perforated plate to deform due to excessive stress. And the power plant does not conduct scientific evaluation and treatment on the deformed water distribution plate. After the perforated plate is deformed, the vertical downward water flow velocity at the splicing gap increases, and the huge impact force causes the resin layer to skew, resulting in uneven flow and serious uneven water distribution, leading to problems such as a reduction in the periodic water production volume and unstable effluent water quality of the high - speed mixed bed. Moreover, the deformation of the water distribution plate will cause the gap between the perforated plates to increase, and the resin is more likely to return to the upper part of the perforated plate and enter the water cap through the gap between the perforated plates, blocking the water cap, resulting in an increase in the operating pressure difference and forming a vicious cycle, which will further exacerbate the deformation or even collapse of the water distribution plate. Currently, there is a lack of an effective and systematic damage grading evaluation method, making it difficult to accurately evaluate and timely handle the condition of the water distribution plate.

[0045] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0046] Embodiment 1

[0047] Refer to Figure 1 - Figure 2 , which is the first embodiment of the present invention. This embodiment provides a method and system for detecting and grading the damage of the water distribution plate of a high-speed mixed bed, including:

[0048] This application can effectively solve the above-mentioned problems. Next, multiple embodiments will be combined to elaborate in detail how to implement the method for detecting and grading the damage of the water distribution plate of a high-speed mixed bed;

[0049] Figure 1 Figure 1 shows a flowchart of a method for detecting and grading the damage of the water distribution plate of a high-speed mixed bed, including:

[0050] S1. Use a 3D scanner to perform grid measurement on the water distribution plate to measure the degree of deformation;

[0051] In the embodiment of this application, performing grid measurement on the degree of deformation is to use a 3D scanner to perform 1:1 modeling on the water distribution plate of the high-speed mixed bed to obtain appearance feature information.

[0052] In the embodiment of this application, obtaining appearance feature information includes obvious physical damage signs such as cracks, breakages, and deformations.

[0053] In an alternative embodiment, performing grid measurement on the degree of deformation is to use structured light measurement technology. Structured light measurement technology projects light with a known pattern onto the water distribution plate. When these lights encounter the surface of the water distribution plate, they will deform due to the unevenness of the surface. The camera captures the deformed light pattern and calculates the three-dimensional shape of the water distribution plate surface through an algorithm. Select a suitable structured light projection device to ensure that it can project a pattern with sufficient density; place the water distribution plate on a stable platform to ensure that it does not move during the scanning process; turn on the structured light projection device and project the pattern onto the water distribution plate; use a high-resolution camera to capture the pattern on the water distribution plate surface from multiple angles; transmit the captured images to a computer and use specialized 3D reconstruction software to process the images and calculate the three-dimensional coordinates of the water distribution plate surface; compare the original model and the scanned model through the software to identify physical damage signs such as cracks, breakages, and deformations; generate a three-dimensional model of the water distribution plate and a deformation analysis report for subsequent maintenance or replacement decisions.

[0054] In an alternative embodiment, the grid measurement of the deformation degree uses laser scanning technology. The laser scanning technology determines the exact position of the water distribution plate surface by emitting a laser beam onto the water distribution plate surface and measuring the time or phase change of the reflected laser beam. By scanning the entire surface, a three-dimensional model of the water distribution plate can be constructed. Select a laser scanner suitable for the size and accuracy requirements of the water distribution plate; ensure that the surface of the water distribution plate is clean, without reflection or obstruction, so that the laser can be effectively reflected; start the laser scanner and perform point-by-point scanning of the water distribution plate according to the preset scanning path; the laser scanner records the three-dimensional coordinate information of each point; import the collected data into three-dimensional modeling software to reconstruct the three-dimensional model of the water distribution plate; use software tools to compare the standard model and the scanned model to analyze the deformation degree and damage condition.

[0055] S2. Simulate the water distribution uniformity index of the water distribution plate during operation;

[0056] In the embodiment of the present application, simulating the water distribution uniformity index of the water distribution plate during operation includes calculating the water distribution uniformity data of the water distribution plate using the CFD simulation method.

[0057]

[0058] Among them, γa is the water distribution uniformity index; φi represents the vertical component velocity of the i-th unit surface, m / s; represents the average value of the vertical component velocities of each unit surface on the entire cross-section, m / s; A i —— The area of the i-th unit surface, m2.

[0059] In an alternative embodiment, the water distribution uniformity index of the water distribution plate during operation can also be tested using a physical model. The physical model test is used to verify the rationality of the water distribution plate design. By constructing a scaled-down model and simulating the actual operating conditions under laboratory conditions, the hydraulic performance of the water distribution plate can be initially evaluated. In the model test, by installing flow meters and velocimeters at different outlets of the water distribution plate, the water flow rate and velocity of each outlet can be measured, and thus the water distribution uniformity index, such as the uniformity coefficient (UC), can be calculated. According to the results of the physical model test, the design of the water distribution plate can be optimized. By adjusting the structural parameters of the model, such as the aperture size, distribution, and angle, a better water distribution effect can be achieved. The physical model test provides pre-test data for the application of the actual water distribution plate, reducing the risk and cost of directly testing on actual equipment.

[0060] In an alternative embodiment, the water distribution uniformity index of the simulated water distribution plate during operation can also use Particle Image Velocimetry (PIV) technology. PIV technology provides visualization of the internal flow field of the water distribution plate. By capturing the movement of tracer particles in the fluid with a high-speed camera, the water flow distribution can be visually observed. PIV technology can collect flow field data at high resolution, including information such as velocity vectors and eddy current distributions. These data are crucial for understanding the hydraulic characteristics of the water distribution plate. By processing and analyzing the data collected by PIV, the water distribution uniformity index, such as the standard deviation of the velocity distribution, can be accurately calculated, thereby more accurately evaluating the performance of the water distribution plate. PIV technology allows for dynamic monitoring of the water distribution performance of the water distribution plate under different operating conditions, which helps to identify performance changes of the water distribution plate under different operating states.

[0061] S3, based on the deformation angle and the water distribution uniformity index simulated by CFD, conduct a primary assessment of the damage degree of the water distribution plate;

[0062] In the embodiment of the present application, the primary assessment includes obtaining the deformation angle by 1:1 modeling of the water distribution plate through a 3D scanner and calculating the water distribution uniformity data by CFD simulation. This requires clarifying the object target, modeling, selecting the mesh type and solver, etc. Then, compare the deformation angle and the uniformity index with the preset threshold, and the threshold is determined based on experimental data and experience. By comparing, judge the damage degree of the water distribution plate, providing a basis for the secondary rating and subsequent maintenance and repair, so as to achieve an effective preliminary assessment of the damage condition of the water distribution plate of the high-speed mixed bed.

[0063] S4, conduct a secondary damage degree rating according to the assessment result.

[0064] In the embodiment of the present application, the secondary damage degree rating includes conducting a secondary damage degree rating according to the primary assessment result.

[0065] The damage levels at least include mild damage, moderate damage, and severe damage.

[0066] Mild damage: The deformation angle α of the water distribution plate ≤ 10°; there is no obvious damage on the appearance; the water distribution uniformity index 0.76 ≤ γa < 0.8.

[0067] Moderate damage: The deformation angle of the water distribution plate 10° < α ≤ 20°; there are slight cracks or deformations; the water distribution uniformity index 0.53 ≤ γa < 0.76.

[0068] Severe damage: The deformation angle α of the water distribution plate > 20°; there are serious cracks and damages; when the deformation of the water distribution plate is more than 20°, due to the generation of a recirculation zone, the water distribution uniformity index does not decrease but increases; therefore, the damage degree is not evaluated by the water distribution uniformity index.

[0069] Minor damage is characterized by slight damage to the appearance and a small deviation in the uniformity of water distribution; moderate damage is characterized by a certain degree of appearance damage and a significant deviation in the uniformity of water distribution; severe damage is characterized by severe damage to the appearance and a serious non-uniformity of water distribution.

[0070] In summary, the present invention discloses a method and system for detecting and grading the damage of the water distribution plate of a high-speed mixed bed, including: using the computational fluid dynamics (hereinafter referred to as CFD) simulation method to calculate the water distribution uniformity data of the water distribution plate, and obtaining the first fitting function of the target under the CFD simulation conditions; obtaining the first fitting function of the target under the CFD simulation conditions; according to the first fitting function, comparing the deformation angle of the water distribution plate and the water distribution uniformity index with the preset threshold values to evaluate the degree of damage. The advantages of the method for detecting and grading the damage of the water distribution plate of a high-speed mixed bed in this application compared with the prior art are that the existing water distribution research relies on physical experiments, which takes a long time to prepare and implement and requires a large amount of resource investment. However, the present invention uses CFD to simulate the water distribution uniformity index, eliminating the need for actual experimental setups, saving a large amount of time and cost, and accelerating the R & D process. In terms of design optimization, traditional methods are limited by experimental conditions and it is difficult to explore multiple parameters in a short time. Our method can quickly simulate and adjust parameters multiple times, improving the design quality and performance and better adapting to the working conditions. In terms of maintenance and operation, the original technology has no clear grading for judging the damage of the water distribution plate, resulting in blind maintenance, waste of manpower and material resources, and difficulty in ensuring the operation of the unit. Our invention has a clear grading standard, can accurately judge and carry out targeted maintenance, improve efficiency, reduce labor costs, and achieve a major breakthrough in equipment maintenance management, far exceeding the efficiency of the existing technology.

[0071] This embodiment also provides a system for detecting and grading the damage of the water distribution plate of a high-speed mixed bed, including:

[0074] A primary evaluation module that primarily evaluates the degree of damage of the water distribution plate according to the deformation angle and the water distribution uniformity index simulated by CFD;

[0075] A secondary damage rating module that performs a secondary damage degree rating according to the evaluation result.

[0076] The above-mentioned unit modules can be embedded in the processor of the computer device in the form of hardware or be independent of it, or can be stored in the memory of the computer device in the form of software, so that the processor can call and execute the operations corresponding to the above-mentioned modules.

[0077] This embodiment provides a detection and grading evaluation system for the damage of the water distribution plate of a high-speed mixed bed, which consists of a measurement module, a calculation module, a primary evaluation module, and a secondary evaluation module. The modules are connected through a data transmission channel. The measurement module uses a 3D scanner to obtain data on the deformation degree of the water distribution plate; the calculation module calculates the water distribution uniformity index by the CFD method; the primary evaluation module compares it with a threshold based on this and outputs the preliminary evaluation result to the secondary evaluation module. The secondary evaluation module conducts a more refined secondary grading evaluation based on the preliminary evaluation, comprehensively considering material characteristics, service life, working environment, etc., using an advanced algorithm, providing a basis for the maintenance and repair strategy, and is completed by the processor executing a program. Its input device is a data interface connected to the monitoring device to receive raw data, and the output device is a display terminal to display the evaluation result. Each module operates in coordination to achieve accurate evaluation.

[0078] This embodiment also provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the following steps are implemented:

[0079] Use a 3D scanner to perform grid measurement on the water distribution plate for the deformation degree;

[0080] Simulate the water distribution uniformity index of the water distribution plate during operation;

[0081] Conduct a primary evaluation on the damage degree of the water distribution plate according to the deformation angle and the water distribution uniformity index simulated by CFD;

[0082] Conduct a secondary damage degree rating according to the evaluation result.

In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through experiments.

[0085] The following further describes the present invention in detail with reference to the accompanying drawings:

[0086] The actual deformation of the water distribution plate is as Figure 3 shown. The model replaces it with a partial spherical surface, and the angle correspondence is as Figure 4 shown. The influence of the gaps in the water distribution plate and the blockage of the water caps is not considered.

[0087] As Figure 4 shown, it presents the actual deformation angle α condition of the water distribution plate of the high-speed mixed bed in an embodiment of the present invention.

[0088] As Figure 5 shown, it shows the definition of the deformation angle of the water distribution plate of the high-speed mixed bed in the simulation model in an embodiment of the present invention.

[0089] As Figure 6As shown, it depicts the specific characteristics of the water distribution plate of the high-speed mixed bed in a slightly damaged state. In the slightly damaged state, there may be some subtle structural changes or surface damages to the water distribution plate, such as local small deformations, slight wear marks, or loosening of a small number of connecting parts, etc.

[0090] As Figure 7 shown, it shows the situation of the medium damage degree of the water distribution plate of the high-speed mixed bed. Compared with the slight damage, the structural and performance changes of the water distribution plate are more obvious in the medium damage, which may be manifested as larger area deformations, damage or failure of some components, and more serious wear.

[0091] As Figure 8 shown, it presents the condition of the water distribution plate of the high-speed mixed bed in a severely damaged state. Severe damage means that the structural integrity of the water distribution plate is severely damaged, and there may be large-area fractures, severe deformations that cannot be repaired, and complete damage of key components, etc.

[0096] Set boundary conditions and initial conditions: Define boundary conditions such as inlets, outlets, and walls, such as flow velocity, pressure, etc. Set the initial conditions to provide initial values for the initial state of the fluid flow.

[0097] Select a solver and physical model: Select a suitable CFD solver according to the characteristics of the problem. Determine the applicable physical model. In this simulation, the Realizable model is selected to calculate the fluid flow.

[0098] Solve the calculation: Run the solver to perform the calculation, solve the fluid mechanics control equations, monitor the calculation process, and ensure the calculation converges stably.

[0100] Figure 9 This is the CFD simulation data record, which details the flow field distribution and the y - velocity distribution on the resin surface when the deformation angles are 0°, 5°, 10°, and 15°, and gives the corresponding water distribution uniformity index γa, which are 0.803, 0.757, 0.756, and 0.640 respectively.

[0101] The flow field distribution is presented in the form of an image through different numerical ranges of the velocity magnitude (VelocityMagnitude), and the y - velocity distribution is shown as an image of the velocity value (YVelocity) distribution on the resin surface.

[0102] In the embodiments of the present application, the relationship between the water distribution uniformity index γa and the deformation angle α of the water distribution plate is as Figure 3 shown, and the binomial fitting result is as shown in Equation (1):

[0103] γ α = 0.795 + 0.0007α - 0.0007α 2
