Stress Analysis of Key Equipment in Carbon-Based Catalytic Multi-Pollutant Control Technology

The desulfurization and denitrification tower is the core equipment of the carbon-based catalytic multi-pollutant synergistic control technology. Its design strength ensures the system’s pollutant removal efficiency and stable operation. This study utilized ANSYS finite element analysis software to establish a three-dimensional model of the tower and divide high-precision grids. Combined with the load analysis, calculation and work condition analysis under actual conditions, the deformation and stress distribution of the tower body, as well as the film stress and bending stress of each component, were calculated, and strength verification and stress assessment were conducted. When ignoring the calculation error, the overall design strength of the tower body meets the requirements, but the local reinforced beam stress exceeds the limit, so it is recommended to replace the steel with a material with a higher allowable stress value.
