摘　　要：针对哈尔滨市某猪舍改造新增冬季通风热回收装置的问题,设计了一种套管式复合换热风管装置。通过计算得到装置的传热系数为6.69W/(m^2·K),换热面积为141m^2,通风量是4032m^3/h,热回收量是25.9kW,造价为12192元。每年减少二氧化碳排放量达59.7t,减少二氧化硫排放193.8kg,减少氮氧化物排放168.7kg。Reconstruction project of a poultry housing in Haerbin city required a new-built ventilation waste heat recovery equipment. Double-pip eair duct heat exchanger was designed to realize this purpose. Many parameters were confirmed by calculation. That is, heat transfer coefficient 6.69 W/(m2·K), heat transfer area 141 m2, ventilation volume 4 032 m3/h, total heat recover 25.9 kW, equipment cost 12 192 yuan. Results showed reducing CO2 emission 59.7 t, SO2 emission193.8 kg, NOx emission168.7 kg every year.
