Description

technical field [0001] The present invention relates to an intelligent calculation module and an intelligent calculation method in an intelligent design system for a structure of a denitrification reactor. Intelligent calculation of the denitrification reactor structure in the power environmental protection industry. Background technique [0002] SCR (Selective Catalytic Reduction) method is the most widely used and most mature flue gas denitrification technology in the world. In this technology, the reactor is the core component of the SCR device, which provides NOx and NH in the flue gas 3 Generate N on the catalyst surface 2 and H 2 The O place, its main function is to carry the catalyst, provide space for the denitrification reaction, and at the same time ensure the smooth flow of the flue gas and the uniform distribution of the airflow, creating conditions for the smooth progress of the denitrification reaction. [0003] The development time of the denitrification p...

AI Technical Summary

Problems solved by technology

[0007] 1. There is no proprietary finite element structure design software for denitrification reactor;

[0008] 2. There is no clear design basis for the design of the denitrification reactor structure;

[0009] 3. The material mechanical performance index of the denitrification reactor structure under the action of high temperature cannot be automatically calculated according to the temperature and steel information, and needs to be manually calculated and then manually input;

[0010] 4. There is a lack of research on the relationship between allowable stress method calculation and limit state method calculation for denitrification reactors;

[0011] 5. The large-scale finite element structure calculation can only be based on one structural model. The denitrification reactor structure often requires the designer to manually adjust the model in order to carry out the next structural calculation. The process is relatively complicated.

Structural calculation and structural model adjustment cannot be linked automatically in the background of the computer;

[0012] 6. In each structural calculation, the user needs to set the relevant design parameters of the calculation, such as component connection information, grid division, load combination and other pre-processing information for the calculation, which need to be set by the designer himself. These settings are cumbersome and easy to set Unreasonable so as to affect the final calculation results

[0013] The above-mentioned problems are common problems when finite element calculations are used for the structure of conventional denitrification reactors. Because these problems are calculated by large-scale finite element software, users need to do a lot of pre-processing work during structural calculations. These pre-processing tasks are open. , can be set according to the experience and understanding of the designer, which facilitates manual intervention, but it also increases the workload of the designer, and at the same time brings security and economic risks to the structural calculation
