Production method of biochar ceramsite particle filler
The invention discloses a production method of a biochar ceramsite particle filler. The production method comprises the steps of heating and stirring, mechanical dehydration, pressure forming and granulation, particle preheating, aerobic pyrolysis, combustion, wet maintenance and the like. The technical characteristic that heat is released in the low-temperature aerobic pyrolysis process is utilized, and the heat conduction bottleneck problem of a traditional anaerobic or anoxic pyrolysis technology is solved; the output of combustible gas is effectively controlled to be lower than the explosion limit concentration, and the safety of the system is improved; liquid products are reduced and liquid phase products are removed by utilizing an instantaneous combustion technology, so that the product quality is guaranteed. A spatial porous biochar ceramsite structure is formed, the porosity and the specific surface area are increased, spatial communication of internal holes and external holes is achieved, and the environmental decontamination capacity of the product is greatly improved. The initial mechanical strength of the wet-based particles is formed by using a pressure forming technology; the mechanical strength of dry-basis particles is formed through the melting effect of the waste plastic residues in low-temperature pyrolysis; and the permanent mechanical strength is formed by utilizing industrial waste volcanic ash activity and a wet curing technology.
本发明公开了一种生物炭陶粒颗粒填料生产方法，包括加热搅拌、机械脱水、压力成型造粒、颗粒预热、有氧热解、燃烧、湿养护等步骤。本发明利用低温有氧热解过程放热的技术特点，解决了传统无氧或缺氧热解技术热传导瓶颈问题；有效控制可燃气体产生量低于爆炸极限浓度提高系统的安全性；减少液体产物并利用瞬时燃烧技术去除液相产物，保障了产品质量。本发明形成空间多孔生物炭陶粒结构，不仅提高孔隙率和比表面积，还实现内部孔和外部孔的空间连通，大幅提升产品的环境除污能力。本发明利用压力成型技术形成湿基颗粒初始机械强度；废塑料残渣在低温热解中熔融作用形成干基颗粒的机械强度；利用工业废弃物火山灰活性及湿养护技术形成永久机械强度。
