摘要:銦主要是從鉛鋅冶煉的副產(chǎn)品中提取。60年代，人們就用溶劑萃取法分離和提純銦。生產(chǎn)采用浸出-萃取回收工序，但總回收率不高。因此，要提高銦總回收率，除對浸出工藝進行改進外，從萃取工藝上尋找更好的箱式水平萃取條件，提高銦的萃取率，是提高總回收率的途徑之一。 在設計中，老師給定了條件，選擇對萃取相的改進，作了物料平衡，水系平衡，萃取箱的設計與計算，以及設備的選擇根據(jù)實際需要及可能性，對車間做了布置，取其優(yōu)點。盡量采用先進設備、結構、材料及新工藝。做到技術上先進，經(jīng)濟上合理，又減少環(huán)境污染。 關鍵詞：銦；車間；設計
ABSTRACT:Indium byproduct of mainly from zinc smelting extract. In the 1960s, people PNP solvent extraction separation and purification of indium. Production adopts leaching - extraction recovery work, but total recovery is not high. Therefore, to improve indium total recovery, in addition to leaching process improvement from the outside, seeking better extract craft level extraction conditions, enhances crate indium is to increase extraction ratio of total recovery of one of the path. In the design, the teacher given conditions of extraction phase, choose the material balance, improve water balance, extraction box design and calculation, and the equipment choice according to the actual need and possibility, as far as possible, with advanced equipment. Structure. Materials and new technology. Be technologically advanced and economically rational, reduce the pollution of the environment. Keywords: Indium ; Workshop ;Design |
