Simulation And Analysis Of Earthquake Stress By ZLX-1600 Ion Exchange Unit

With the development of uranium industry, the application of uranium ion exchange column is increasingly widespread .And its scale and number are also growing. In recent years, the recovery of the international uranium industry not only has made states increase their uranium production, but also has put forward higher requirements on the uranium extraction equipment. China is a multi-national earthquake. Uranium mines distribute widely, many of which are in the seismic activity zone .However, China has entered a new peak of the earthquake. In order to make sure uranium this highly radioactive and long-term contamination element absolutely safe ,we must analyze dynamic response of the earthquake and evaluate seismic performance of the uranium extraction equipment to take the necessary measures to reduce the direct and secondary disasters. In the seismic analysis of the uranium extraction equipment, we use a simplified analysis method at present .At first ,we put actual three-dimensional structure into a simplified one-dimensional problem,and then establish analytical method to calculate based on certain assumptions. FET analysis has also been a certain amount of application, but it can't be applied universally in the engineering design because of the definition of self computational procedures and the accuracy or size. Therefore, this paper use the existing large-scale FET software uranium to calculate and analyze the seismic properties of the ion exchange column .This article first do a simplified theory analysis of earthquake dynamic response for uranium ion exchange column, on this basis, use large-scale FET analysis software ANSYS to calculate response of static and earthquake dynamic of uranium ion exchange column. It does specific FET numerical calculation on spontaneous vibration characteristics and seismic response when uranium ion exchange column is in cans and reservoir fluid state respectively .After comparing and analyzing , it shows that the numerical results by ANSYS is different from by theoretical analysis. Numerical analysis can reproduce the phenomenon of "Support foot distorted" and "Drum-shaped deformation" of. It could occur "depression" deformation between uranium ion exchange column and pillars. This is ageometric nonlinear problems. zone is round. In the analysis, the "depression" deformation is multi-mode vibration pattern, which can be divided into no-twisting and twisting vibration pattern. Because of the fluency of the additional weight of liquid of uranium ion exchange column in vibration, the spontaneous characteristics of the uranium ion exchange column are very different when it is with liquid and without liquid. The difference between considering substrate (with factory) contact characteristics and no considering is so big that it impacts the earthquake Dynamic Response of storage tanks. Generally, the natural cycle is shorter when the uranium ion exchange column is full, while the uranium ion exchange column is empty. The calculation and analysis results of this article provide important reference for static design and seismic design of the uranium ion exchange column.
