摘　　要：利用鸡舍换气余热干燥鸡粪是近年来发展起来的新型鸡粪处理方法,其利用鸡舍通风换气时所排废气的余热对鸡粪进行干燥,不仅能对鸡舍通风排出的废气进行再利用,还能对鸡粪进行有效的脱水处理。文章介绍了鸡舍换气余热干燥鸡粪技术的工作原理、特点及近几年来国内外该技术的研究与应用进展,总结了目前鸡舍换气余热干燥鸡粪技术在国内应用时遇到的干燥速率低和氨排放高等问题,分析了国内外在应对夏季鸡舍排风湿度高、梅雨季节、连续阴雨天和冬季气温较低情况下利用辅助热源提高干燥速率的方法和存在的不足之处,并基于节约能源和减少空气污染的原则,对鸡舍换气余热干燥鸡粪设备的优化提出了相关建议。Drying chicken manure with exhaust air from chicken house is a new manure management method developed in recent years,which refers to the thermal drying method of removing water in poultry manure by using waste heat of exhaust air from chicken house,and the method can not only reuse the waste heat from poultry house but also can reduce the moisture of the manure.This paper introduced the working principle and characteristics of the technology of drying chicken manure with exhaust air from chicken house,and described the research and application of the technology in the domestic and overseas,summarized the problems of low drying rate and high ammonia emission from the domestic application case,and analyzed the methods of us-ing auxiliary heat source to increase drying rate under the conditions of high humidity of exhaust air from chicken house,plum rains season,continuous rainy days and low temperature in winter and its shortcomings,put forward suggestions for optimizing the equipment and method of drying chicken manure with waste heat of exhaust air from chicken house based on the principle of sav-ing energy and reducing air pollution.
