摘　　要：脱硫塔结构在矿山化工等多个行业中作为常见的脱硫装置,其稳定性至关重要。以某矿山脱硫塔结构为研究对象,开展了考虑流固耦合的脉动风作用下脱硫塔结构的抗风稳定性研究,探讨了开孔高度、开孔角度和开孔半径对脱硫塔结构抗风稳定性的影响规律。研究结果表明:不同开孔参数对脱硫塔结构抗风稳定性的影响非常显著,开孔角度对于结构抗风稳定性的影响最大;当开孔角度小于120°时,结构抗风极限承载力下降趋势较为明显,当开孔角度大于120°时,降幅趋于缓和;随着开孔高度的增大,结构抗风极限承载力先减小后增大;随着开孔半径的增大,结构抗风极限承载力逐渐减小,基本呈现线性关系。研究结果对脱硫塔结构开孔参数设计具有重要意义。The desulfurization tower structure is a common desulfurization device in many industries such as mining and chemical industry,and its stability is very important.Taking the structure of a mine desulfurization tower as the research object,the wind-resistant stability of the desulfurization tower structure under the action of pulsating wind considering fluid-solid coupling was studied.The influence of opening height,opening angle and opening radius on the wind-resistant stability of the desulfurization tower structure was discussed.The results show that the influence of different opening parameters on the wind-resistant stability of the desulfurization tower structure is very significant,and the opening angle has the greatest influence on the wind-resistant stability of the structure.When the opening angle is less than 120°,the wind-resistant ultimate bearing capacity of the structure decreases obviously.When the opening angle is greater than 120°,the decrease tends to be moderate.With the increase of the opening height,the wind-resistant ultimate bearing capacity of the structure decreases first and then increases.With the increase of the opening radius,the wind-resistant ultimate bearing capacity of the structure gradually decreases,basically showing a linear relationship.The research results are of great significance to the design of opening parameters of desulfurization tower structure.
