摘　　要：为了解决目前飞机喷漆机库通风系统存在的通风量大、送风射流到达喷漆工作区时速度衰减大、通风能耗高等问题,实地测试了喷漆现场的风速和污染物浓度,建立并验证了喷漆机库及其通风系统的数学物理模型。基于相关规范要求、实测数据及工艺运行情况,提出了喷漆通风系统安全运行的分区和约束条件。通过对改进工况的模拟,得到了送风管高度下降6 m时送风量可降低至60%的匹配关系。相比标准工况,改进工况的通风系统可实现降低能耗37.4%,降低碳排放量160 kg/h。In order to solve the problems in the ventilation system of the painting hangar,such as large ventilation volume,large speed attenuation when the jet reaches the painting working area,and high ventilation energy consumption,the wind speed and pollutant concentration at the painting site are tested,and the mathematical and physical models of the painting hangar and its ventilation system are established and verified.Based on the requirements of relevant specifications,measured data and the actual situation of process operation,the partition and constraint conditions for the safe operation of painting ventilation system are given.Through the simulation of improved working conditions,the matching relationship that the air supply volume can be reduced by 60%when the height of the air supply pipe is reduced by 6 m is obtained.Compared with standard working conditions,the ventilation system with improved working conditions can reduce energy consumption by 37.4%and reduce carbon emissions by 160 kg/h.
