FCC stripper is one of very important device in the production of chemical equipment. Mainly used in oil refining industry. This paper is the structure design of the stripper is calculated, the structure was established, and a series of problems in the analysis, obtained the result. The utility model were design and check of the skirt, cylinder and so on, and take over the reinforcement design. The cylinder body segment, in order to calculate the mass loading. Then each segment of the lumped mass in each center, calculate the seismic loads, and seismic moment. The calculation of wind load and then the whole tower section, in order to obtain the wind moment. Combined with the seismic moment and the wind moment, to get the maximum bending moment. And check the stability of the skirt cylinder, and the strength and stability of hydraulic condition check. The design and calculation of the foundation ring and anchor bolt. Structure design part, choose the appropriate column, and the tray, downer plate, a liquid disk and overflow weir structure size design. Finally, check and calculation of the flange and gasket.Keywords: Catalytic cracking；Stripper；Structure design 目 錄1引言12設(shè)計(jì)內(nèi)容22222344566 裙座驗(yàn)算部分7789 裙座與塔殼連接焊縫驗(yàn)算910183
