摘　　要：在普通喷嘴蒸汽喷射式热泵的基础上介绍了新型双喷嘴蒸汽喷射式热泵,通过分析和比较发现,在相同的操作条件下,双喷嘴结构能有效地提高喷射器的喷射系数和改善由于工作流体压力降低而造成的设备操作性能恶化,提高蒸汽喷射器运行的稳定性和纸机干燥部的干燥能力,降低能耗。n new style of double nozzles steam-jet ejector is introduced on the basis of single nozzle steam-jet ejector. Through analysis and research, we find that the double nozzles in prove the performance of steam ejector effectively compared with a single nozzle on the same operation, and it has favorable effect in improving the ability and stability of steam ejector, and improving the dry level and reducing the energy consumption, especially, for lower primary steam pressure. So it has intensive values of application and promotion.
