Selection principle of cyclone dust collector

1. The amount of purge gas from the cyclone dust collector should be consistent with the amount of dust gas actually required for disposal. Select the diameter of the cyclone dust collector should be as small as possible, if the air volume required larger, can be used in several small diameter cyclone dust collector in parallel is appropriate. 2. Cyclone dust collector inlet velocity be maintained at 18 ~ 23 m/s, dust removal efficiency is too low when the speed is too low; if the speed is too high, resistance loss and power consumption will be increased, and the dust removal efficiency is not obvious. 3. Selecte the cyclone dust collector which has low resistance loss, less power consumption, simple structure and easy maintenance. 4. The minimum dust particle that can be trapped by the cyclone dust collector should be slightly smaller than the dust particle size in the gas to be treated. 5. When the temperature of dusty gas is high, should pay attention to heat preservation to avoid moisture condensation in the precipitator. If the dust does not absorb moisture, the dew point is 30 ~ 50 ?, the temperature of the precipitator should be at least 30 ? higher, if the dust absorbent is strong (such as cement, gypsum and alkali dust, etc.), the dew point is 20 ~ 50 ?, the temperature should be higher than dew point dew point temperature 40 ~ 50 ?. 6. Cyclone structure must have a good seal, to ensure no air leakage. In particular, negative pressure operation, should pay attention to the reliability of the discharge lock air device. 7. Flammable and explosive dust (such as coal) should be equipped with explosion-proof device. The usual practice of explosion-proof device is to add a safety explosion-proof valve on the inlet pipe. 8. When the viscosity of the dust is small, the maximum allowable dust concentration is related to the diameter of the cyclone cylinder, that is, the larger the diameter, the greater the dust concentration concentration is allowed.
