大多数工业粉尘控制系统使用离心风机来推动和控制空气运动。对于净化后空气压力大于大气压力的那些系统,如高密度气力输送系统,则是例外情况。虽然风机本身并不能代表投资总额的大部分,但所需的直接能源费用却肯定取决于风机的运行情况。这里并没有考虑在寒冷的冬季 Most industrial dust control systems use centrifugal fans to propel and control air movement. For those systems where air pressure after purification is greater than atmospheric pressure, such as high density pneumatic conveying systems, this is an exception. Although the wind turbine itself does not represent a large part of the total investment, the direct energy costs required certainly depend on the operation of the wind turbine. There is no consideration here in the cold winter
