Spray axial flow fan with side wall spray pipes

Abstract

The invention discloses a spray axial flow fan with side wall spray pipes. The spray axial flow fan comprises a current collector, a fan air duct, a motor, a hub, a movable vane, and drain booms. The movable vane is provided with radial water retaining devices. The spray axial flow fan is characterized in that the side wall spray pipes are arranged between the motor and the hub, the side wall spray pipes input water flow through annular water ducts out of the fan air duct, and the spray pipe head water outlet of the side wall spray pipe, extending in the fan air duct, faces the movable vane blades, and sprays water along the movable vane blades which axially rotate. Since the side wall spray pipes and the radial water retaining devices are arranged, compared with an existing spray axial flow fan, the spray axial flow fan can obviously improve efficiency of the fan and reduce power consumption of the motor.

Description

technical field [0001] The invention relates to a fluid mechanical device, in particular to a spray axial fan. Background technique [0002] Axial flow spray fans are used in many industries. In the textile industry, in order to maintain the temperature and humidity of the textile workshop and ensure the quality of textile products, an air conditioning device must be installed. The widely used textile air-conditioning system now takes the traditional spray fan as the core, through the large amount of fine water droplets generated by the spray fan, the water mist droplets and the air are directly exchanged for heat and mass, thereby adjusting the humidity and temperature of the air to achieve the purpose of air conditioning . The traditional spray fan integrates the air supply function of the general fan and the function of generating spray. It is an axial flow fan formed by installing a spray device on the basis of the ordinary axial flow fan. The basic structure of the t...

Problems solved by technology

The spray axial flow fan effectively improves the figure 1 The energy consumption of the fan increases and the efficiency decreases under the condition of a large water-air ratio of the spray fan. However, the setting of the water spray ring at the inlet of the spray axial flow fan greatly increases the resistance of the fan flow channel, disturbs the airflow at the inlet of the impeller, and causes the fan to fail. The flow rate and efficiency are significantly reduced, and the ring water spray pipe is easy to vibrate and loosen under the impact of high-speed airflow, so further improvement is needed

[0006] Although the appearance of the spray axial flow fan has greatly reduced the power consumption of the old textile air conditioning system, the spray fan, as the key equipment of the new textile air conditioning system, has its own narrow range of working conditions for the water-air ratio of the traditional spray fan. The improved pipe resistance of the spray fan has many problems such as a large drop in efficiency
