Semi-physical Simulation Of Bag Filters With Integrated Data Processing And Visualization Research

Bag filter was taken as a large-scale dust removal equipment, which commonly usedin coal, metallurgy, steel, electric power and other fields. With the increasingly seriousenvironmental situation and the relevant regulatory gradually strengthen, bag filters marketand the product user customization requirements increased. Problems of low level productdesign, long cycle, difficult to conduct experiments and difficult to guarantee theperformance are very obvious, Therefore, there is urgent need to explore a fast, lean,innovative research and development method to develop new products of large dustremoval equipment. The semi-physical simulation method with integrated data processingand visualization technique was adopted to the bag filter digital prototype design process oflarge-scale environmental protection equipment. The method accessing the part ofhardware testing to the machine simulation model was adopted to obtain prototypeperformance analysis test data more quickly and accurately. Besides, the integrated andvisual data processing tool was developed to solve the evaluation and optimization ofdigital prototype design performance, and in order to provide a new technical support forthe bag filter product innovation research and rapid lean development. The paper relatedresearch subject of “comprehensive test and validation platform for digital bag filterprototype” was funded of Sinoma group. The creative contributions and conclusions maybe summarized as follows.First of all, studying the product digital prototype integrated simulation technology, adigital prototype integrated semi-physical simulation method was proposed. And the keytechnology of the digital prototype integrated semi-physical simulation for new productimplementation was analyzed.Secondly, based on the analysis of bag filter structure and working mechanisms, thescheme accessing filter part to the bag filter digital prototype integrated semi-physicalsimulation was researched. The design of simulation model and the hardware access systemwas completed.Then, analyzing the performance evaluation requirements and main influencingfactors of bag filter, the main performance for flow field of intelligence, integration,visualization technology was researched. Then based on CFD numerical simulation, themulti-objective parameter optimization method combining with the BP neural network andgenetic algorithm, was used to realize the comprehensive optimization of design parameters.On the basis, the bag filter digital prototype semi-physical simulation system whichintegrated data processing and visualization application was developed. The function modelof digital prototype semi-physical simulation and the integrated and visual test dataprocessing was finished, which was faced new product. The digital prototype integratedsemi-physical simulation and design optimization of192series new product was initiallyachieved.Research and application shows that on the basis of the existing experimentalconditions, the digital prototype integrated semi-physical simulation technology, can takegreater advantages of digital model and high fidelity simulation technology, and achievethe combination of fast, lean and customized requirements for the new product innovationand research and development. It is a new ideas for large industrial product development.
