The air velocity of the dust removal equipment is calculated as follows:
除尘设备气流速度计算应该合理地计算。 1: The air velocity calculation of the dust removal equipment should be reasonably calculated. The speed calculation is too small, and the dust in the air flow is easy to be full, which seriously damages the normal operation of the dust removal equipment system. The calculation of the air velocity is too high, and the resistance of the duct will be greatly increased, which is too wasteful, friction will also accelerate the wear of the pipe body, and reduce the life of the pipe.
除尘设备直管里面内的气流速度计算，一般大过粉尘吸风口的气流。 2: The calculation of the air velocity in the straight pipe of the dust removal equipment is generally larger than that of the dust suction port. The airflow of horizontal and inclined pipes should be greater than the speed of dust floating, and higher than the speed of airflow in straight pipes. 4 倍。 Therefore, the calculation of the airflow speed of the general dust removal equipment is actually 4 times faster than the theoretical calculation .
通常对除尘设备气流速度计算时，为了不让粉尘掉落，除尘设备风管里面要保持运输粉尘必需保持最低风速。 3: Generally, when calculating the airflow speed of the dust removal equipment, in order to prevent the dust from falling, the minimum wind speed must be maintained in the dust pipe of the dust removal equipment to keep the transportation dust.
6-12m ／ s 。 There is generally no dust falling problem in the exhaust duct behind the dust collector, and the gas flow rate is designed to be 6-12m / s .
6-12m ／ s ， The gas velocity in the pipes of large-scale industrial dust removal equipment systems is often designed at 6-12m / s .
带有粉尘的气体在风管里面的流速也可以采取下面方法计算得出。 4: The velocity of dust-laden gas in the duct can also be calculated by the following method.
1 ． In a straight pipe, the gas flow rate is greater than the suspension speed of the dust particles in the air duct. The polishing and dust removal equipment should take into account that the uneven speed of the inner surface of the air duct can take away the dust particles on the pipe wall. Particle suspension speed ． 3-1 . 倍，比较难和风管厚度比较大的取 1.3 倍，反之取 1.7 倍。 7 times, which is more difficult and the thickness of the duct is 1.3 times, and 1.7 times.
What are the properties of dust in general ducts?
The general dust properties are divided into three types:
：较细的粉尘 1 : finer dust
较粗的颗粒粉尘 2: coarser particle dust
：可能带有大块的混全性粉尘 3 : May contain large mixed dust
