Method for preparing porous ceramic by sintering waste incineration fly ash and lead-containing waste
The invention discloses a method for preparing porous ceramic by sintering waste incineration fly ash and lead-containing waste. Domestic garbage incineration fly ash and lead-containing waste (waste cathode ray tube) are used as main materials, borax, bentonite, silicon nitride, tricalcium phosphate and other auxiliary materials are added at the same time, the materials are fully mixed to serve as sintering raw materials, and high-temperature sintering is carried out. According to the method, elements such as calcium, silicon and aluminum in the fly ash and the waste are fully utilized to prepare the porous product, so that the solid waste can be recycled, partial natural resources such as clay and the like can be replaced, and the method has better economic benefits and environmental benefits. Through the chlorination volatilization reaction in the collaborative sintering process of the chlorine-containing household garbage incineration fly ash and the lead-containing waste, collaborative recovery of chlorine and lead in the secondary fly ash can be achieved.
本发明公开了一种垃圾焚烧飞灰协同含铅废料烧结制备多孔陶瓷的方法。以生活垃圾焚烧飞灰和含铅废料(废弃阴极射线管)为主料，同时加入硼砂、膨润土、氮化硅、磷酸三钙等辅料，经过充分混合作为烧结原料，进行高温烧结。本发明充分利用飞灰与废料中的钙、硅、铝等元素，制备多孔性产品，不仅可以实现固废的再生利用，而且可以替代部分黏土等自然资源，具有较好的经济效益和环境效益。含氯的生活垃圾焚烧飞灰与含铅废料协同烧结过程的氯化挥发反应，能够实现二次飞灰中氯和铅的协同回收。
