废旧电路板非金属材料粉的能量利用实验与分析

Experimental Study and Analysis on Use of Energy From Non-metallic Materials of Waste Printed Circuit Boards

为了实现废旧电路板非金属材料粉的资源化再利用,通过对废旧印刷电路板非金属材料的焚烧过程和机理进行研究与分析,采用流化床焚烧装置处理已经被破碎的废旧印刷电路板非金属材料粉,在提取其中的玻璃纤维的同时,使非金属粉中的树脂尽量充分焚烧,并且测量排气温度,从而确定废旧印刷电路板中树脂焚烧之后能量利用的可行性。结果表明:在600℃的床温下,废旧电路板非金属粉已经充分燃烧并能提取出高纯度的玻璃纤维,同时焚烧烟气中存在大量可利用的热能,且二英排放符合环保要求。

By the analysis and comparison of the incineration process and mechanism of the non-metals from the waste printed circuit boards, in order to actualize the reuse of the non-metallic materials from the waste printed circuit boards, the fluidized bed was used as an incineration plant to treat the broken non-metallic materials from the waste printed circuit boards in this study. While extracting the glass fibre and resin was burnt as fully as possible and the temperature of the exhaust gas was measured in order to determine the feasibility of the use of the energy from the burning of the resin. The results showed that at the fiuidized bed temperature of 600℃ the resin had fully burnt, and the glass fibres were extracted, at the same time the amount of heat energy from the exhaust gas could be used and the dioxins were undetected.
