Simple analysis of the classification efficiency of industrial dust collectors
Dust removal efficiency as the performance limitation of industrial dust collectors is very large, and it is greatly affected by the size of dust particles Generally speaking, in the same device and under the same operating conditions, due to the difference in dust particle dispersion, its performance is also significantly different. Classified dust removal efficiency can better reflect the performance of industrial dust collectors.
Classified dust removal efficiency and refers to the dust removal efficiency for a certain particle size range, which reflects the average particle size at the outlet and the amount of dust within a certain particle size range, and a certain particle size range. The amount of dust trapped inside.
The classification efficiency of different dust collectors is different. The particle size and density of dust affect the classification efficiency of industrial dust collectors. At the same time, the classification efficiency is also related to the cohesion and adsorption of dust. It has a great relationship with physical properties such as electrification, so it is impossible to simply divide the order of merits and demerits of each type of precipitator according to the grading and dedusting efficiency of each type.
Generally speaking, cyclone dust collectors and scrubber dust collectors have the most obvious performance on particle size classification and dust removal efficiency, followed by other types of industrial dust collectors.
Accurately grasping the dust particle size and the classification efficiency of various dust collectors is the basis for selecting the type of dust collector. The corresponding relationship between the dust particle size of various dust collectors and their classification and dust removal efficiency is different. When the particle size is above a few microns, a centrifugal dust collector should be selected. When the dust particles below a few microns account for most of the dust, a scrubber should be selected. , electrostatic precipitator or filter-type industrial dust collector, etc.
