摘要:
浓缩再沸器属于换热设备，是一个能够交换热量，同时有汽化空间的一种特殊热交换器。为使物料在热交换器内循环加热，通常在加热室中间开腔，形成中心开孔的管板，即环形管板，该管板无法通过常规计算确定其结构强度。以浓缩再沸器环形管板为研究对象，采用数值模拟技术，通过正交试验和响应面优化等方法，讨论了浓缩再沸器环形管板的结构应力强度及设计方法。利用ANSYS Workbench中的响应面分析模块，分析了各结构参数相互作用对管板最大应力的影响。研究结果表明，环形管板厚度与壳程筒体厚度组合敏感性显著。使用响应面优化设计模块对再沸器环形管板进行结构优化，优化后环形管板厚度减薄42.3%，筒体厚度减薄25%，环形管板的结构强度与刚度均符合标准要求。
Abstract:
The concentrated reboiler is a type of heat exchanger, which is a special category of heat exchanger capable of exchanging heat and containing an evaporation space. In order to facilitate the circulation of heating materials within the heat exchanger, a cavity is typically created in the center of the heating chamber, resulting in the formation of a central perforated tube sheet, commonly referred to as an annular tube sheet. The structural strength of this tube sheet can′t be determined by conventional calculations. Accordingly, the annular tube sheet of the concentration reboiler was selected as the subject of investigation, and numerical simulation technology was used to investigate the structural stress intensity and design methodology of the aforementioned tube sheet. This was achieved by utilizing orthogonal experiments and response surface optimization. The influence of the interaction between various structural parameters on the maximum stress of the tube sheet was analyzed using the response surface analysis module in ANSYS Workbench. The results show that the combination sensitivity of the annular tube sheet thickness and the shell side cylinder thickness is significant. The response surface optimization design module was used to optimize the structure of the annular tube sheet of the reboiler. After optimization, the thickness of the annular tube sheet was reduced by 42.3% and the thickness of the cylinder was reduced by 25%. The structural strength and stiffness of the annular tube plate were found to meet the standard requirements.
