Cyclone affecting the performance of many factors, coupled with the complexity precipitator air flow pattern, therefore, the performance of multi-cyclone dust collector according to some form of dust in certain conditions, determined by experiments. Through theoretical analysis and studies have shown that the main factors affecting dust summarized as follows: 1) The diameter of the cyclone increases, that is, only for the dust collector for geometrically similar amplification equipment resistance willing to be decreased, but the precipitator efficiency is decreased, the cost increase; 2) when the air volume is constant, if the change in the area of ​​the air inlet on the efficiency and resistance to have a significant impact. Such as expanding air inlet area, reducing the flow rate of the gas inlet, the fluid resistance at this time and efficiency of the device has fallen; contrary, increase inlet gas flow rate, in favor dust separation, collection efficiency, but the device resistance is also increased. 3) and the appropriate increase in dust cone portion of the length of the cylinder, almost no change of the resistance of the device, to improve the removal efficiency is beneficial; 4) the diameter of the exhaust pipe and the core insertion depth changes, the precipitator a significant impact on performance. In a range appropriate to reduce the diameter of the exhaust core tube advantageous to improve the efficiency of dust, but also a corresponding increase in resistance of the device; increase the exhaust pipe insertion depth of the core, no significant effect on the collection efficiency, the device has brought increased resistance The negative factors; 5) inlet dust concentration increased, the removal efficiency generally increased; 6) the particle density and particle size increases, the removal efficiency will be significantly improved; 7) Jaw crusherthe flue gas temperature increases, viscosity increases, to improve the collection efficiency disadvantage; 8) Equipment tightness had a significant effect on the collection efficiency, especially cinder valve tightness should pay more attention. When the hopper discharging device dust into the air leakage reached 15%, the dust collection efficiency is almost close to zero. In summary, the performance of the cyclone dust collector structure, the relative size of each of the components and operating conditions. However, among them the dust precipitator performance are interrelated, mutual constraints, the size of the change, change only in a certain range, such as the corresponding increase or decrease beyond the scope of the performance have been advantageous to improve dust factor, as by other factors and transformed into a negative factor. Therefore, when designing or improving cyclone device must take account of the relationship between various factors, round consideration. Please indicate Henan YuFeng Heavy Machinery
