| 摘 要： | 4浮选设备及其发展趋势
浮选是脱墨的关键环节，也是脱除胶粘物的重要环节。在脱墨方面，有人认为：油墨粒子小于10μm时，可用洗涤法分离，5-100μm时可用浮选法分离，100-400μm时可用离心除渣分离，200μm以上的油墨粒子可用筛浆机分离。其实，有实验证明，300-500μm的油墨粒子在气泡直径为0.5mm时也有较好的浮选脱墨速率常数，见图17，图18，图19。

| Abstract: | The present condition and development trend of the principal equipment for repulping, screening, cleaning, flotation and hot disper-sion in wastepaper deinking system are introduced in this paper. For the pulping equipment, the rotor drum continuous pulper is a direction ofdevelopment; for the screening equipment, the structure of the screen frame, the precision of the screen slot and the combination of the stages ofscreens are paid more attention; for the floatation tank, Ecocell type floatation tank is the most common, but the new flotation column will bedeveloped in the future; for the heat dispersion equipment, the more perfect disc type heat dispersion system is among the development trend.In a word, low energy consumption, high efficiency, automation, continuousness, large specification and high yield are the trend of development. |
