Stress Analysis and Structural Optimization of Large-sized Tangential Nozzle of Viscosity Control Tower
For purpose of ensuring efficiency of air-liquid separation and designing tower strength reason-ably,ANSYS software was used to establish geometric model of the cylinder and tangential nozzle of the device,and the stress distribution of common rectangular section and the optimized structure(oblong sec-tion,rounded rectangular section)was obtained and influence of the nozzle shape and the ribbed plate set-ting on the stress was analyzed.The results show that,under the condition of better satisfying separation requirements,the stress concentration between the cylinder and the pipe with the rounded rectangular sec-tion can be largely reduced and the stress distribution at the tangential opening becomes more uniform.Meanwhile,assessing stress strength of the rounded rectangular section according to the analysis and design standard indicates that the results meet the requirements specified in the standard.
