摘要

针对胶合板生产过程中单板干燥后二次蒸汽难以回收利用的问题，基于文丘里原理，设计了一种单板干燥蒸汽回收系统。通过对工作流体流量、引射蒸汽流量、喷嘴直径及混合室直径之间的关系等关键技术的研究，同时借助数字化设计技术，设计出回收系统中的关键部件—引射器，实现了在低背压状况下将冷凝水畅通地引回到冷凝水回收罐，再回送到锅炉，完成二次蒸汽的回收再利用。应用结果显示，该回收系统具有操作简单、运行稳定的特点，可达到节能降耗、减排增效的目的。

Abstract

In order to recover the secondary steam after veneer drying, based on the Venturi principle, a veneer drying steam recycling system was developed. Through research on the working fluid flow, the ejector steam flow rate, the nozzle diameter, and the relationship between the diameter of mixing chamber, by applying the digital design technology, a key component–the ejector of the steam recycling system was designed and constructed. The system successfully completes the secondary steam recycling by condensing steam, returning the condensed water to the recycling tank, and then back to the boiler at a low back pressure condition. The pilot operation demonstrated that the recycling system is easy and stable to conduct, while it efficiently achieves the targets of energy saving and emission reduction.
