Dry dust collector and wet dust collector compare which utilization rate is high, there are many types of separator, different types of suitable materials are also different, different models are also made according to the customer's requirements for material fineness.
The common separator are cyclone separator, three separation separator, centrifugal separator, special separator for coal mill, special separator for calcium powder, etc. Later, a lot of high-efficiency powder concentrators and high-efficiency three separation powder concentrators were developed. They are the new generation varieties that improved on the original basis and increased the yield.
A number of guide vanes with "concave" grooves are evenly arranged in the middle between the cage rotor and the outer shell. The dusty gas must enter the annular classification space composed of the guide vanes and the cage rotor along the tangential direction from a number of gaps about 15mm between the guide vanes. Due to the complete sidewall effect of the guide vanes, the content of fine ash in the coarse ash is greatly reduced and the separation efficiency is improved The efficiency of the first level is greatly improved.
The coarse ash falling into the coarse ash hopper is washed by the lower updraft, and the fine ash in the coarse ash is brought into the classification area again for classification. At the same time, the increase of the concentration also means that the dust thickness attached to the unit area of the filter bag will increase in unit time, and the pressure loss will also increase. In this case, the separator manufacturers often make the equipment work normally by increasing the frequency of ash cleaning, but this will increase the expansion frequency of the filter bag, intensify the friction between the filter bag and the bag cage, reduce the service life of the filter bag and make the filter material invalid. The failure of filter material will in turn lead to the increase of filter bag pressure loss and the increase of equipment operation resistance.
