Hypersonic hair dryer wholesaler.Determination of wind speed in dust removal pipelines

　　Ventilation pipeline adopts φ one hundred and sixty-eight × 8 steel pipes are led from the underground storage tank to the settlement tank on site. The settlement tank on site is a cement tank with a height of 10m and a diameter of 4m. In order to prevent the dust generated at the inlet of the underground storage tank from spreading around, and to ensure that the dust around the inlet flows to the storage tank with the surrounding air under negative pressure, the control wind speed at the inlet is set to 0.5m/s. According to this control wind speed, the wind speed inside the dust removal pipeline is 22.6m/s. The relationship between the resistance along the path of a steel pipe with an inner diameter of 150mm and the wind speed inside the pipe has been experimentally determined. It can be observed that when the wind speed is 22.6m/s, the frictional resistance of the pipeline is 45pa/m. Based on the resistance along the path and the wind speed in the pipeline, according to the above formula, the pressure loss of the system, that is, the wind pressure required for the hair dryer, is 5331pa, and the air volume is 1656m3/h. Under the conditions of meeting wind pressure and air volume, choose 9-26-5A electric hair dryer with a speed of 2900r/min and a power of 12.9KW, and choose MC60-II pulse bag filter.
