| 中文摘要: |
| 针对化工和食品加工行业废碱液回收排放要求,设计了一套新型双效逆流升膜蒸发机械压缩式热泵废碱液回收系统,并给出了系统流程图.该系统以板式换热器作为蒸发器,在保证充分换热的前提下,通过对一、二效蒸发冷凝器进行热平衡计算以及对系统能效进行经济性分析,分析、比较了多效蒸发和热泵蒸发过程,从而得到系统性能指标的变化规律.结果表明:机械压缩式热泵蒸发技术的制热性能系数较高,可更好地提升节能效果,实现经济效益最大化,并对保护环境起到了至关重要的作用. |

| According to the demands of the waste lye recycling emissions from chemical industry and food processing,a new kind of double-effect adverse countercurrent rising film evaporator mechanical compression heat pump used in the waste lye recycling system is established.The plate heat exchanger was used as evaporator in the system,in this study,the system process is drawn.In the context of full heat,through the first and second effect evaporative condenser heat balance calculation and system economics analysis of energy efficiency,more fully to compare multi-effect evaporation with heat pump evaporation,then we know the relationships of the variation of system performance.It turned out that,the mechanical compression type heat pump has a higher thermal performance coefficient.Better to realize the energy saving effect and economic benefit maximization.For the protection of the environment have played a vital role. |
