Analysis of bag filter general air is acid free
Analysis of bag filter general air is acid free. When the moisture content is constant, the relative humidity varies greatly in different humidity; when the air temperature is constant, the humidity increases, the relative humidity also increases.
Under normal temperature, when the dry powder is crushed, screened, processed and transported by water spray, the relative humidity of the air is very low. Even if the moisture content of the powder is large, the moisture content in the dust will evaporate and move into the air in vain, reducing the humidity on the dust surface, thus avoiding the possibility of adhesion and filtration. Because the dust is suspended in the air, or attached to the surface of the filter bag, surrounded by the flowing air, the contact area of the air is very large, so the process of water natural evaporation moving into the air is very rapid. It can be seen that the moisture content of the object does not exceed the allowable range, that is, there is no obvious degree of bonding of the wetted material, so the bag filter can be used. Generally speaking, if the moisture content of the dust has reached the moisture content of the adhesive filter bag, it will not dust, and there is no need to dust. The moisture content of materials is not fugitive dust in the range of 3-30% due to different types and sizes of materials. The moisture content is closely related to meteorological conditions and environmental temperature, because the dust gas is empty: the content is small in sunny days and winter; the moisture content is large in rainy days and summer.
