WHAT IS CENTRIFUGAL DUST COLLECTOR?

The Centrifugal Dust Collector is an apparatus precipitating and collecting the dust separating the particles from gases with centrifugal force providing rotating movement to those thick particles with high gravity.

As for the dusts with large particles, the dust collector is a sort of cyclone independently used demonstrating solid performance, and utilized as a pre-treatment facility for high efficiency dust collector for removing fine particles.

The pressure loss, primary element influencing on performance, having the dimension ratio, inlet condition and treatment speed work as variables.

The design of Centrifugal Dust Collector should consider the state of dust particles, displacement, inflow velocity, selection of blower and etc., which substantially influences the performance of dust collector.

TYPE OF COLLECTOR

1. Tangential Entry Type Cyclone

The Tangential Entry Type Cyclone induces the dirty gases flowing inside of external enclosure, as sorted by the overhead type, spiral winding type and etc. The velocity of in-flowing gas is in general 7~15m/sec., which shows relatively low interference on dust removing rate having the diameter of internal enclosure work as major element determining the performance.

The press loss, when the velocity of inlet gas reaches about 12m/sec, is around 100mmH2O with the overhead type, and about 20% lower pressure loss with the spiral winding type.

2. Axial Inlet Type Multi-cyclone

The Axial Inlet Type Multi-cyclone is used for the application where the amount of gas to be treated in massive requiring high dust collecting efficiency. The cyclone is composed of multiple, small diameter cyclones arranged in parallel aligning the treatment gas inlet in parallel with the centrifugal dust collector shaft. The gas to be treated flows in from the top section of dust collector generating and discharges outside of outlet with reversed rotation after flowing inside to the lower section, while activating the circulation of flow alongside the spiral guide kit installed at the inlet.

The Axial Type is capable of treating more gases approximately three times in comparison with other types of cyclones, and further, easy to distribute the dirty gases evenly to each of unit cyclones.

The velocity of inlet gas is about 12m/sec. with the pressure loss of around 70~80mmH2O.
