摘　　要：为优化空气压缩机除油雾系统,用除油雾空气引射器代替传统的除油雾风扇以达到节能的目的。给出了适用于除油雾空气引射器的结构尺寸计算关系式。运用MATLAB计算程序,在给定的初始条件下(如被引射气体的质量流量、压力、温度,主流气体的压力、温度和出口背压)计算除油雾空气引射器的主要结构尺寸。根据计算结果设计的除油雾空气引射器完全能够满足除去油箱油雾的使用要求。In order to optimize the oil demisting system of air compressors,making use of the oil-demisting air ejector to replace the traditional demisting fan to save energy was implemented,including to present the calculating relation to make them suitable for the structure dimension calculation of oil-demisting air ejector.At the given conditions(the mass flow rate,pressure and temperature of ejected oil-mist gas,the pressure and temperature of high-pressure instrument air(primary flow gas),and the back pressure of export),the main structure dimension of the oil-demisting air ejector can be calculated by the MATLAB program.The results showed that,the ejector designed according to the calculating result can meet the requirement of oil-demist in the oil tank.
