| 摘要:针对制浆造纸工艺中能耗与碳排放的问题，本课题提出了一种基于热能循环利用的余热水驱动吸收式热泵低温制冷技术。通过对某公司冰水系统集成改造实际工程运行数据的深入分析，得出了余热水驱动低温制冷技术与装备的运行特性和技术经济性。经评估可知，每年可节省蒸汽18.5万t，年收益约2 072万元，减少CO2排放2.3万t，减排效益明显。 |
| Abstract:To address the high energy consumption and carbon emissions in the papermaking process， this study proposed a low-temperature refrigeration technology based on heat recovery using waste heat water-driven absorption heat pumps. Through in-depth analysis of actual engineering operation data from an ice water system retrofitted in a papermaking plant， the operational characteristics and techno-economic viability of the waste heat water-driven low-temperature refrigeration technology and its equipment were presented. According to the evaluation， it was estimated that 185 000 tons of steam could be saved annually， generating an annual revenue of approximately 20.71 million yuan. Additionally， CO₂ emissions would be reduced by 23 000 tons， demonstrating significant emission reduction benefits. |
