[0046] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0047] It should be noted that in related technologies, the design of denitrification SCR systems typically employs CFD methods for flow field prediction and analysis. During this analysis, due to limitations such as computer memory, the model is simplified to improve computational efficiency. Steel structures are not included in the model, and components like the rectifier grid and catalyst are replaced with porous media models. These simplified models are usually two-dimensional. Understandably, two-dimensional models offer faster computation speeds, and in actual production with tight deadlines, faster numerical simulations improve efficiency and better guide actual production. However, using only two-dimensional models can lead to inaccurate analysis results for some structures.
[0048] To address the aforementioned issues, this application proposes a method and apparatus for three-dimensional analysis of two-dimensional numerical simulation results of a denitrification SCR system. This method enables the simulation of the operation of the denitrification SCR reactor based on a first two-dimensional geometric model to obtain first two-dimensional numerical simulation results; the simulation of the operation of the denitrification SCR reactor based on a second two-dimensional geometric model to obtain second two-dimensional numerical simulation results; the determination of multiple target monitoring points on the target monitoring surface based on target monitoring surface; the determination of first weight values of first physical quantities for each of the multiple target monitoring points in the first two-dimensional geometric model based on first simulated physical quantity data; the determination of second weight values of second physical quantities for each of the multiple target monitoring points in the second two-dimensional geometric model based on second simulated physical quantity data; and the determination of three-dimensional physical parameters for each of the multiple target monitoring points based on the first weight values, second weight values, first simulated physical quantity data, and second simulated physical quantity data. Thus, while ensuring improved computational efficiency of the numerical analysis of the denitrification SCR reactor model, the accuracy of the structural analysis results in the denitrification SCR system is improved through three-dimensional analysis of the two-dimensional numerical simulation results.
[0049] Figure 1 This is a flowchart illustrating a method for three-dimensional analysis of two-dimensional numerical simulation results of a denitrification SCR system, as described in an embodiment of this application.
[0050] like Figure 1 As shown, the method for three-dimensional analysis of the two-dimensional numerical simulation results of the denitrification SCR system includes:
[0051] Step 101: Simulate the operation process of the denitrification SCR reactor based on the first two-dimensional geometric model to obtain the first two-dimensional numerical simulation results.
[0052] In this embodiment of the application, the first two-dimensional numerical simulation result includes the first simulated physical quantity data of the target detection surface in the first two-dimensional geometric model.
[0053] In this embodiment of the application, the first two-dimensional geometric model is a two-dimensional geometric model of the denitrification SCR reactor established on the plane formed by the first direction and the second direction.
[0054] As a possible implementation example, a two-dimensional denitrification system model is established based on the denitrification SCR reactor. This model corresponds to the first and second directions of the denitrification system model, which can be defined as the X and Y directions. A first two-dimensional geometric model of the denitrification SCR reactor is established on the plane formed by the first and second directions. The operation process of the denitrification SCR reactor is simulated based on the first two-dimensional geometric model, and the first two-dimensional numerical simulation results are obtained.
[0055] Step 102: Simulate the operation process of the denitrification SCR reactor based on the second two-dimensional geometric model to obtain the second two-dimensional numerical simulation results.
[0056] In this embodiment of the application, the second two-dimensional numerical simulation result includes the second simulated physical quantity data of the target detection surface in the second two-dimensional geometric model.
[0057] In this embodiment of the application, the second two-dimensional geometric model is a two-dimensional geometric model of the denitrification SCR reactor established on the plane formed by the second direction and the third direction.
[0058] In this embodiment of the application, the third direction is perpendicular to the first direction and the second direction, respectively.
[0059] It is understandable that, based on the first and second directions, a third direction perpendicular to the first and second directions can be determined, thereby forming a three-dimensional space.
[0060] As a possible implementation example, a two-dimensional denitrification system model is established based on the second and third directions of the denitrification SCR reactor. These two directions can be defined as the Y direction and the Z direction. A second two-dimensional geometric model of the denitrification SCR reactor is established on the plane formed by the second and third directions. The operation process of the denitrification SCR reactor is simulated based on the second two-dimensional geometric model, and the second two-dimensional numerical simulation results are obtained.
[0061] As a possible example, the above-mentioned first two-dimensional geometric model can be established by the following method:
[0062] Step d1: CFD numerical simulation establishes a two-dimensional denitrification system model based on the two-dimensional plane formed by the denitrification SCR reactor system in the X and Y directions at a 1:1 scale.
[0063] Step d2 involves meshing the aforementioned two-dimensional geometric model to discretize it, meaning that the actual spatial continuous entity is described using a finite number of mesh nodes. The mesh near the rectifier grille support beam requires local refinement. During mesh generation, quadrilateral meshes are primarily used, with triangular meshes employed for transitional sections requiring local refinement.
[0064] Step d3: Import the above grid data into the fluid calculation software.
[0065] Step d4: In the fluid dynamics calculation software, establish a turbulence model, using the standard Ke two-equation model to simulate the flue gas flow inside the SCR denitrification reactor. Establish a discrete phase model to simulate the ash particle flow inside the SCR denitrification reactor.
[0066] Step d5: Based on the flue gas flow rate, dust flow rate, and inlet cross-sectional dimensions, calculate the inlet boundary conditions and discrete phase injection port boundary conditions.
[0067] Step d6: Use fluid analysis software to perform iterative calculations until the flue gas flow tends to stabilize.
[0068] Optionally, during iterative calculations, the flue gas phase flow field can be calculated first, and the solid phase can be coupled after the gas phase flow calculation has stabilized. Stability here means that the calculation equations for momentum, energy, etc., have reached equilibrium.
[0069] Step d7 involves focusing on statistically analyzing the simulation results of various parameters in the X and Y directions at the target detection surface.
[0070] It is understandable that the second two-dimensional geometric model can also be constructed using the methods proposed in steps d1-d7 above.
[0071] Step 103: Based on the target monitoring surface, determine multiple target monitoring points on the target monitoring surface.
[0072] Optionally, the aforementioned multiple target monitoring points can be randomly selected from multiple target monitoring points, or they can be selected according to preset rules.
[0073] Step 104: Based on the first simulated physical quantity data, determine the first weight value of the first physical quantity of each of the multiple target monitoring points in the first two-dimensional geometric model; based on the second simulated physical quantity data, determine the second weight value of the second physical quantity of each of the multiple target monitoring points in the second two-dimensional geometric model.
[0074] In some embodiments of this application, step 104 includes:
[0075] Step a1: Based on the first simulated physical quantity data, determine the first physical quantity of each of the multiple target monitoring points in the first two-dimensional geometric model.
[0076] It is understandable that the first simulated physical quantity data includes physical quantity data at different locations in the first two-dimensional geometric model. The first physical quantity of each target monitoring point in the first simulated physical quantity data can be found within the first simulated physical quantity data. Each target monitoring point can have one or more first physical quantities.
[0077] Step a2: Determine the average value of the first physical quantities based on multiple first physical quantities.
[0078] As a possible implementation example, the same first physical quantity of the above multiple target monitoring points can be added together, and the result of the addition can be divided by the number of target monitoring points to obtain the average value of the first physical quantity.
[0079] Step a3: Based on the first physical quantity and the average value of the first physical quantity of each of the multiple target monitoring points, determine the first weight value of each target monitoring point.
[0080] In this embodiment of the application, step a3 specifically includes: for each target monitoring point, dividing the first physical quantity of the target monitoring point by the average value of the first physical quantity to obtain the first weight value of the target monitoring point.
[0081] For example, in the first two-dimensional geometric model obtained in the X and Y directions, the simulation results of the first physical quantity of 5 to 10 target detection points are selected, the mean value Da of the first physical quantity of these 5 to 10 target detection points is calculated, and the first weight value σi = Di / Da is calculated for each target detection point.
[0082] Step a4: Based on the second simulated physical quantity data, determine the second physical quantity of each of the multiple target monitoring points in the second two-dimensional geometric model.
[0083] Step a5: Determine the average value of the second physical quantities based on multiple second physical quantities.
[0084] Step a6: Based on the second physical quantity and the average value of the second physical quantity of each of the multiple target monitoring points, determine the second weight value of each target monitoring point.
[0085] In this embodiment of the application, step a6 specifically includes: for each target monitoring point, dividing the second physical quantity of the target monitoring point by the average value of the first physical quantity to obtain the second weight value of the target monitoring point.
[0086] It is understandable that the method for determining the second weight value is the same as that for determining the first weight value, and will not be elaborated here.
[0087] It should be noted that there is no distinction between the order in which steps a1-a3 and steps a4-a6 are executed.
[0088] Step 105: Based on the first weight value, the second weight value, the first simulated physical quantity data, and the second simulated physical quantity data, determine the three-dimensional physical parameters of each of the multiple target monitoring points.
[0089] In some embodiments of this application, both the first analog data and the second analog data include scalar physical quantities, and step 105 includes:
[0090] Step b1: In response to the fact that the first and second physical quantities of the target monitoring point are scalar physical quantities, the first weight value and the second weight value are multiplied together to obtain the three-dimensional weight value of the target monitoring point.
[0091] For example, a scalar physical quantity can be gray concentration D. Gray concentration D has no direction, so the physical quantity parameter value of the target detection point can be obtained.
[0092] Step b2: Average the average value of the first physical quantity and the average value of the second physical quantity to obtain the average value of the three-dimensional physical quantity.
[0093] Step b3: Multiply the average value of the three-dimensional physical quantity by the three-dimensional weight value of the target monitoring point to obtain the three-dimensional physical quantity of the target monitoring point.
[0094] As an example of possible implementation, in the second two-dimensional geometric model obtained in the Y and Z directions, the average value of the second physical quantity Db and the second weight value σ of each target detection point are determined. j Then, the three-dimensional weight value σ of each target detection point is calculated. ij :
[0095] σ ij =σ i ×σ j
[0096] Calculate the three-dimensional physical quantity D of the target monitoring point:
[0097]
[0098] In some embodiments of this application, both the first analog data and the second analog data further include vector physical quantities; the first physical quantity includes a first physical quantity in a first direction, a first physical quantity in a second direction, and a first physical quantity in a third direction; the second physical quantity includes a second physical quantity in a first direction, a second physical quantity in a second direction, and a second physical quantity in a third direction; the first weight value includes a first weight value in a first direction, a first weight value in a second direction, and a first weight value in a third direction; the second weight value includes a second weight value in a first direction, a second weight value in a second direction, and a second weight value in a third direction; step 105 further includes:
[0099] Step c1: In response to the fact that the first and second physical quantities of the target monitoring point are vector physical quantities, for each of the first, second and third directions, the first weight value and the second weight value are multiplied to obtain the three-dimensional weight value of the target monitoring point.
[0100] For example, a vector physical quantity can be the gas phase velocity V of the flue gas, which can be decomposed into the velocity Vx in the x-direction and the velocity Vy in the y-direction.
[0101] Step c2: Average the average value of the first physical quantity and the average value of the second physical quantity to obtain the average value of the three-dimensional physical quantity.
[0102] Step c3: Multiply the average value of the three-dimensional physical quantity by the three-dimensional weight value of the target monitoring point to obtain the three-dimensional physical quantity of the target monitoring point in that direction.
[0103] In the first two-dimensional geometric model obtained in the X and Y directions, an average of 5 to 10 target detection points are selected. The two components Vx and Vy of the physical quantity V for each target detection point are determined, and the first physical quantity of Vx and Vy is determined. In the second two-dimensional geometric model obtained in the Y and Z directions, the two components Vz and Vy of the physical quantity V for each target detection point are determined, and the second physical quantity of Vz and Vy is determined.
[0104] Taking Vy as an example, using the weight value determination method proposed in any embodiment of this application, the first physical quantity average value Vya, the second physical quantity average value Vyb, and the proportion weights τi and τj of the physical quantity Vy at each point in the Y direction are determined. Then, τi and τj are multiplied to obtain the three-dimensional weight value τij. Using τij and the three-dimensional physical quantity average value, the three-dimensional physical quantity Vy of the target monitoring point in the Y direction can be calculated.
[0105]
[0106] It is understandable that Vx and Vz are calculated using the above method, and will not be elaborated upon here.
[0107] In some embodiments of this application, both the first two-dimensional geometric model and the second two-dimensional geometric model include a rectifier grid sub-model, a rectifier grid support beam model, and a catalyst layer sub-model.
[0108] According to the three-dimensional analysis method of two-dimensional numerical simulation results of a denitrification SCR system according to embodiments of this application, the operation process of the denitrification SCR reactor is simulated based on a first two-dimensional geometric model to obtain a first two-dimensional numerical simulation result; the operation process of the denitrification SCR reactor is simulated based on a second two-dimensional geometric model to obtain a second two-dimensional numerical simulation result; multiple target monitoring points on the target monitoring surface are determined based on the target monitoring surface; a first weight value of a first physical quantity for each of the multiple target monitoring points in the first two-dimensional geometric model is determined based on the first simulated physical quantity data; a second weight value of a second physical quantity for each of the multiple target monitoring points in the second two-dimensional geometric model is determined based on the second simulated physical quantity data; and three-dimensional physical parameters for each of the multiple target monitoring points are determined based on the first weight value, the second weight value, the first simulated physical quantity data, and the second simulated physical quantity data. Thus, while ensuring improved numerical analysis and calculation efficiency of the denitrification SCR reactor model, the accuracy of the structural analysis and calculation results in the denitrification SCR system is improved through three-dimensional analysis of the two-dimensional numerical simulation results.
