“…e relevant study on an electrostatic precipitator is mainly focused on the dusting principle or filtration characteristics [9,10], the collection efficiency or dusting method [11][12][13], the collected dust or the particulate matter [14,15], the analysis of the operating [16,17], and the electrode system or recovery system [18][19][20] but ignored the study of its bearing structure [21,22]. e main frame structure is often designed and transformed by companies with analogy method and empirical design instead of precise and scientific calculation.…”

e geometric modeling and finite element modeling of the whole structure of an electrostatic precipitator and its main components consisting of top beam, column, bottom beam, and bracket were finished. e strength calculation was completed. As a result, the design of the whole structure of the electrostatic precipitator and the main components were reasonable, the structure was in a balance state, its working condition was safe and reliable, its stress variation was even, and the stress distribution was regular. e maximum von Mises stress of the whole structure is 20.14 MPa. e safety factor was large, resulting in a waste of material. An optimization mathematical model is established. Using the ANSYS first-order method, the dimension parameters of the main frame structure of the electrostatic precipitator were optimized. After optimization, more reasonable structural design parameters were obtained. e model weight is 72,344.11 kg, the optimal weight is 49,239.35 kg, and the revised weight is 53,645.68 kg. Compared with the model weight, the optimal weight decreased by 23,104.76 kg and the objective function decreased by 31.94%, while the revised weight decreased by 18,698.43 kg and the objective function decreased by 25.84%.

Purpose The purpose of this paper is to improve the hydraulic efficiency without changing the overall dimension. The blade profile optimization design of the aero-centrifugal pump based on the biharmonic equation surrogate model has been studied. Design/methodology/approach First of all, Bezier curves and linear function are used to control the annular angle distribution and the stacking angle of blade profile under the MATLAB platform. Grid independence analysis has been studied to find the finest mesh scheme. After the precision comparison of test data and computation fluid dynamics 15 sets of design parameters are carried out as the boundary condition of the biharmonic equation. The efficiency surrogate model of the biharmonic equation is constructed via iteratively solving of a discrete difference equation. The other two surrogate models of response surface model (RSM) and radial basis function neural network surrogate model (RBFNNSM) are compared with the biharmonic equation surrogate model by the standard of modified complex correlation coefficient R2 and root mean square deviation (RSME). Finally, the artificial fish swarm algorithm has been used to find the global optimal design parameters with the objective function of highest efficiency. Findings The results show that the design parameters code conversion method can reduce the number of optimization parameters from five to three, makes the design space become a cube, and compared with RSM and RBFNNSM, the biharmonic equation surrogate model has higher precision with R2 is 0.8958, RSME is 0.1382. The final optimum result of AFSA is at the point of [1 −1 −1]. The internal flow field analysis shows that after optimization the outlet relative velocity becomes more uniform and the wake effect has been significantly decreased. The hydraulic efficiency of the optimized pump is about 59.45 per cent increasing 5.4 per cent compared with a prototype pump. Originality/value This study developed a new method to optimize the design parameters of aero-centrifugal pump impeller based on biharmonic equation surrogate model, which had a good agreement with experimental values within just 15 sets of the original design. The optimization results shows that the method can improve the hydraulic efficiency significantly.

The objective of this work is to test the strength reserve, the working stability, the vibration performance and the dynamic response under stochastic load on the optimized main body frame structure of a type of electrical dust precipitator. The test program is established which is a test process, as well as a feedback process. The strength prototype test is carried out to study the strength reserve of the structure. Based on the mechanical model, the modal analysis, the buckling analysis, and the seismic analysis is carried out using ANSYS to study the working stability and the vibration performance of the structure. The test results show that the strength reserve of the structure is sufficient, the main body structure will not be instability in working, the structure's landscape orientation rigidity is feasible, the two-dimensional rigidity is even, and its torsional rigidity is better. The Maximum lateral displacement and stress meet the standard requirements. Obviously, the main body structure is optimized perfectly and the method is feasible that to do the performance tests after structure optimization design.
