Cyclone dust collector is a type of dust removal device. The dust removal mechanism is to make the dust-laden air flow rotate, and the dust particles are separated from the air flow by centrifugal force and collected on the wall of the device, and then the dust particles fall into the ash hopper by gravity. Each component of the cyclone dust collector has a certain size ratio. The change of each proportional 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 air inlet, and the diameter of the exhaust pipe are the main influencing factors. . Workers should pay attention when using it. When a certain limit is exceeded, favorable factors can also be transformed into unfavorable factors. In addition, some factors are beneficial to improving the dust removal efficiency, but they will increase the pressure loss, so the adjustment of various factors must be taken into account.
