对空分设备中金属孔板波纹规整填料片几何结构进行分析,构建填料片冲制侧面与理想平面间的折边垂距参数模型,通过四面体体积变换法与Taylor级数展开法,得出折边垂距及其误差计算公式,并得到冲制折边几何偏差随着填料直径增大呈幂级增长的结论.改进填料片的生产工艺,减小整个填料长度上折边垂距的误差波动,从而改进气液分离中压降与操作气速的关系.
The piece geometry of structured packing of corrugated metal plate with hole was analyzed,and the parameter model for the ruffled offset between the coining side of packing sheet and the ideal plane was built. The coining ruffled offset and its error calculation formula were derived by using of the method of tetrahedral volume transformation and Taylor series expansion,and in conclusion that the geometrical deviation of the coining ruffled was increasing exponentially with the increase of packing diameter. By means of improving the production technology of the packing piece and reducing the error fluctuation of the coining ruffled offset along the whole packing length,thus the relationship between drop of pressure and operating gas velocity in gas-liquid separation was improved.
