The influence of air dust filter bag and filter wind speed

Influencing factors of filter wind speed of bag filter:.


1. It is necessary to clarify the particle size distribution of the dust in the processing conditions. The particle size of the dust is its basic characteristic. It is an aggregate composed of particles of various sizes. The average particle size is simply used to express this aggregate. Body is far from enough.


2. It is necessary to clarify the viscosity of the dust in the processing conditions. The viscosity is a characteristic of mutual attraction between dust or between dust and the surface molecules of the object. It is important to influence the bag filter and the dust bag property of the dust sticky dust collector. Because the dust removal efficiency and filter resistance depend to a large extent on the ability of dust from the filter material.


3. It is necessary to clarify the bulk density or accumulation specific gravity of the dust handled by the bag filter, that is, the weight of the dust per unit volume. The unit volume includes the volume of the dust particle itself, the volume of air adsorbed on the surface of the dust particle, the micropores of the dust particle itself, and the dust particle. The gap between the dust and clarifying the bulk density of the dust is of great significance for ventilation and dust removal, because it is closely related to the dust removal performance of the dust.


4. It is necessary to clarify the physical and chemical properties of the dust-containing gas of the bag filter under the processing conditions, such as temperature, moisture content, chemical composition and properties. The determination of these parameters is directly and indirectly related to the additional treatment measures for dust removal and the selection of filter wind speed. relationship.
