摘　　要：传统复混肥料造粒、干燥、冷却过程产生大量含杂质废气,影响企业环保排放达标,需要创新技术加以解决。在简要介绍传统造粒技术的基础上对新的造粒技术和采用新热风炉改进干燥技术进行了重点阐述,并总结实施新的尾气处理技术。经过生产实践验证,采用新技术,复合肥生产尾气排放可以达到或低于国家环保排放限值的要求。The granulation, drying, cooling process of traditional compound fertilizer produce a large number of impurities in waste gas, affecting the emission compliance of environmental protection of enterprise, need to be solved by innovative technology. The traditional granulation technology of compound fertilizer is briefly introduced, the new granulation technology and the new hot blast stove improves drying technology are key introduced. The new exhaust gas treatment technology is summarized and carried out, through the production practice verification, using the new techology, the exhaust gas can reach the discharge limits at or below the national environmental protection requirements.
