自20世纪50年代用于矿物加工的Denver槽首次工业应用以来,通过化学添加剂配方和浮选单元/多级浮选设计两方面的改进大大提高了浮选脱墨技术。如今,使用适合的浮选化学和先进的多级浮选可达到较高的油墨去除率/选择性,而且浮选脱墨一直被认为是一项成熟技术。然而,在整个脱墨过程中,浮选单元要承受最高的污泥产生量,并且其对原材料和工艺水质的波动非常敏感。尽管现代浮选脱墨生产线的效率较高,但造纸工业目前仍通过优化浮选单元/多级浮选竭力降低成本(如能源消耗、污泥产生量和污泥处理、过程运行性能),并在脱墨车间和造纸厂探寻浮选脱墨技术的新应用。
Since the first industrial application of the Denver tank for mineral processing in the 1950s, flotation deinking has been greatly enhanced by both chemical additive formulation and flotation cell / multi-stage flotation design. Today, higher ink removal rates / selectivities are achieved using suitable flotation chemistry and advanced multistage flotation, and flotation deinking has long been considered a proven technique. However, the entire deinking process, flotation units to withstand the highest sludge production, and its raw materials and process water quality is very sensitive to fluctuations. Despite the high efficiency of modern flotation deinking lines, the paper industry is still struggling to reduce costs (such as energy consumption, sludge production and sludge handling, process performance) by optimizing flotation unit / multi-stage flotation Explore new applications of flotation deinking technology in deinking workshops and paper mills.
