Cyclone dust collector is a type of dust removal device. The dust removal mechanism is to make the dusty airflow rotate, use centrifugal force to separate and capture dust particles from the airflow, and then use gravity to make the dust particles fall into the ash hopper. Each component of a cyclone dust collector has a certain size ratio, and any change in the ratio relationship can affect the efficiency and pressure loss of the cyclone dust collector. Among them, the diameter of the dust collector, the size of the inlet, and the diameter of the exhaust pipe are the main influencing factors. When using, it should be noted that when a certain limit is exceeded, favorable factors can also be transformed into unfavorable factors. In addition, some factors are beneficial for improving dust removal efficiency, but they can increase pressure loss, so adjustments to each factor must be taken into account.
