摘　　要：针对目前国内锂电池负极材料产能急剧扩张带来的环保问题展开分析,着重分析了现阶段负极预炭化烟气净化系统执行的排放标准和为应对今后日趋严格的环保排放适宜选用的净化工艺。分析预炭化烟气蓄热式焚烧净化工艺存在的难点问题的同时,提出一种烟气直燃式焚烧结合高温烟气预热产品的新工艺,并结合理论计算和工程实践,论证了直燃式焚烧工艺的可行性和经济性。This article introduces the current environmental protection problems caused by the rapid expansion of the carbon anode material production capacity for lithium-ion battery, and analyzes the appropriate means to purify the flue gas produced during the precarbonization process to meet the increasingly strict requirements of the emission standards. Combined with analyzing the difficulties existing in the flue gas purification, this paper puts forward a new process for gas purification of direct combustion incineration combining with preheating products with high-temperature flue gas for energy conservation, demonstrates the feasibility and economy of the process.
