There are many factors that affect the performance of the cyclone dust collector, in general, one for the structural factors, the other factors for the operating conditions.
Structural factors are generally divided into four areas:
1. The entrance with the top: 1) the entrance of the form; generally divided into two direct entrance and eddy current entrance. 2) The top of the dust collector is usually flat, but also has a raised and spiral.
2. Exhaust pipe ordinary cyclone dust collector tube and a number of cylindrical and concentric concentrator with the dust collector. The shorter the insertion depth of the exhaust pipe, the lower the pressure loss.
3. The length and diameter of the dust collector in general length and diameter greater than 2, known as efficient cyclone dust collector; less than 2, the low cyclone dust collector. The former because of the dust in which the residence time is long, so the efficiency is higher.
4. The roughness of the inner wall of the cyclone dust collector wall more likely to cause eddy current, which will increase the fluid resistance and reduce the dust collection efficiency. Therefore, in the manufacture should pay attention to the weld to be smooth, cylindrical and cone this head to strive to smooth.
Factors of operating conditions:
The operating conditions of the dust collector include the gas flow rate, temperature, dust particle size, density and other factors.
1. Gas performance
1) Gas flow The efficiency and resistance of the cyclone dust collector are related to the flow rate of the gas into the dust collector.
2) Gas temperature The gas temperature directly affects the viscosity coefficient of the gas. The viscosity coefficient increases with increasing temperature, while the dust collection efficiency decreases with increasing temperature.
2. The nature of dust
1) Dust particle size The efficiency of the cyclone dust collector is very sensitive to the particle size of the dust. Generally less than 5 umm of particles, its efficiency is low, and greater than 20 ųm particle dust collection efficiency of 90% or more.
2) The density of dust collection dust density higher, the higher the efficiency; when the density reaches a certain value when the smaller particles, the greater the impact of density. But the effect of the actual dust collection range is relatively small.
3) Dust concentration Dust concentration has an effect on the efficiency and resistance of the dust collector. The effect of dust concentration on the performance of the dust collector is due to the increase of the friction loss between the dust particles, the decrease of the rotational speed of the air flow, and the decrease of the centrifugal force, so that the resistance and efficiency are reduced. Increased concentration of dust will produce dust, so that the dust collection efficiency.
So only enough to understand the impact of cyclone dust collector performance factors, in order to better avoid the loss of performance, so that the cyclone dust collector dust collection efficiency to the highest.
