High-efficiency and low-noise axial-flow ventilator of textile air conditioner

The utility model relates to high-efficiency and low-noise axial-flow ventilator of a textile air conditioner, which is mainly used for a humidification ventilating system in an air-conditioning chamber of a textile enterprise, and can also be used on ventilating occasions without corrosive gases. The axial-flow ventilator comprises a flow collector (1), an impeller (2), a machine shell (3) and an electric motor (4), and is characterized in that the impeller (2) is composed of an impeller hub (6) with a spherical surface and 3 to 6 forward leaning-bending airfoil blades (5) which are uniformly distributed on the hub. The axial-flow ventilator has the advantages of large flow, high wind pressure, high efficiency, low noise, wide working area, low producing as well as manufacturing costs and the like, and has good humidifying and ventilating effects for a textile air-conditioning system.
