中文摘要:
      目的 研究凹版印刷机热风干燥系统热能流向与品质,为烘干系统的设计与优化提供理论依据,提高干燥热效率,促进国内凹印机能量审计进一步发展。方法 对凹印机烘干系统进行热力学分析,进行能耗计量。结果 经计算,凹印机烘干系统的热效率只有9.21%,而62.29%高热量气体被直接排出系统,没有得到有效的利用。干燥介质在经过烘箱时,产生的不可逆损失为86.96%,而加热纸张的不可逆损失占到整个烘箱不可逆损失的24.21%。结论 回收利用系统废气热量是提高凹印机烘干系统热效率最有效的途径;此外,降低热风与纸张的换热过程产生的不可逆能量损失也会直接提高凹印机烘干系统热能的品质。
英文摘要:
      The work aims to study the thermal energy flow direction and quality of the hot air drying system in gravure press to provide theoretical basis for the design and optimization on the drying system, improve the heat efficiency of drier, and promote the further development of press energy audit on domestic gravure. The thermodynamic analysis method was used to measure energy consumption on the drying system of gravure press. It was calculated that the thermal efficiency of the hot air drying system in gravure press was only 9.21%, and 62.29% high heat gas was directly discharged out of the drying system, which was not effectively utilized. The result also showed that the irreversible loss in the drying oven was 86.96%, while the irreversible loss to heat the paper accounted for 24.21% of the total irreversible loss in the drying oven when the drying medium passed through the drying oven. Recycling the waste heat of the drying system is the most effective way to improve the thermal efficiency of the drying system in the gravure press. In addition, reducing the irreversible energy loss in heat transfer process between hot air and paper will directly improve the quality of heat energy.
