摘要

PPROBLEM TO BE SOLVED: To drastically save electricity consumption by recovering harmful mercury from a waste phosphor powder contained in a waste fluorescent tube at a low temperature in a short time. PSOLUTION: Mercury is recovered by promoting evaporation of mercury by stirring a phosphor powder in a rotary kiln or stirring the powder with a stirring apparatus and evaporating mercury at a temperature from 250C to 300C for 2 to 6 hours or evaporating mercury at a temperature from 550C to 650C for 1 to 2 hours and cooling the evaporated gas.

要解决的问题：通过在短时间内在低温下从废荧光灯管中包含的废荧光粉粉末中回收有害汞，来大大节省电耗。

解决方案：通过在回转窑中搅拌磷光体粉末或在搅拌装置中搅拌粉末，然后在250°C至300°C的温度下蒸发汞2至6小时，或在250°C的温度下蒸发汞，可促进汞的蒸发，从而回收汞。在550℃至650℃的温度下保持1-2小时，并冷却蒸发的气体。
