摘　　要：作者研制的复合式排雾罩，在结构上结合了外部吸气罩和接受式排风罩两者的特点，并将排风机与排风罩合为一体。对复合式和普通式排风罩，在不同罩口高度和风机转速条件下，分别测定了液面控制速度、罩口吸气速度和排雾效率。结果表明，复合式排雾装置控制速度可达０．３３ｍ／ｓ，排雾效率达８０％，是印染车间散湿设备排雾的有效手段。The complex vapour hood developed by the authors is an incorporate air exhaust fan and hood with both capturing and receiving characteristics.The control velocity over liquid level, face velocity and vapour extraction efficiency have been measured respectively in condition of different hood heights and fan speeds for both the complex and ordinary vapour hoods. The results show that the complex vapour hood is an effective measure in vapour extraction inprinting and dyeing mills, for its control velocity can reach to 0. 33m / s andvapour extraction efficiency to 80%.
