中文摘要:
      热镀锌生产过程产出大量的热镀锌渣,如何有效的回收利用热镀锌渣已成为热镀锌厂节能减排和发展循环经济的重要方向之一。本文综述了从热镀锌渣中回收锌的工艺流程、原理及应用状况,介绍了动态蒸发-高效冷凝新工艺,提出应针对热镀锌渣资源特点和企业优势选择相应的工艺技术,以获得更好的技术经济指标和社会效益。
英文摘要:
      Large amounts of hot-dip galvanizing (HDG) residues were produced during the production of HDG. Therefore, effectively utilization of the HDG residue has become one of the most important directions for a HDG factory to saving energy and reduction emission. Several kinds of technologies, the principles and the application for recovery zinc from HDG residue are summarized in the present paper. It is pointed out that the feasible process for zinc recovery should be selected according to the characteristic of the HDG residue and the factory’s advantage, aims to obtain better technical economic index and social benefits.
