A few parameters of dust collector, the filter is the most crucial wind speed, the first to know the nature of dust laden gas and dust,

1, to know the bulk density of dust or bulk, that is, the unit volume of dust. In the meantime, the unit volume contains dust particle size, dust particle size, air volume, dust particle. It is important to clarify the bulk density of dust, which is very important to the ventilation and dust removal.

2, to know the chemical and physical properties, such as moisture content, temperature, chemical composition and properties. The judgment of these parameters has a direct direct contact with the dust removal and disposal method and the selection of filtering wind speed. If some dust containing gas rich in chloride and other chemical components, usually chloride is easy to absorb moisture, such as not to adopt additional measures to be able to cause dust bag bag".

3, to know the particle size distribution of dust. Particle size is the basic characteristic, it is the composition of particles with different particle size, simply using uniform particle size to characterize the aggregation is not good.

4, to know the dust viscosity. Is a kind of viscous characteristics between dust and dust or between surface molecules attract each other. For bag filter, the effect of viscosity is more outstanding, because of the dust removal power and filtration resistance to a large extent depend on the ability to remove dust from the filter material.

In the process of planning and the relevant parameters can not be ignored, it is necessary to know that all of the above four aspects of the collection of data, from China's current dust removal equipment planning practice, there is still a certain degree of difficulty.
