How to choose a dust collector

How to choose a good dust collector? To choose a good dust collector, you must correctly understand and understand the relationship between the dust removal efficiency and the filtration air speed, dust removal performance and filtration resistance.

Among several technical parameters of the dust collector, the air speed of the filter is the key. First, we must know the nature of dusty gases and dust. So how do you know the nature of the dusty gas?

(1) Understand the bulk density or specific gravity of dust, that is, the weight of dust per unit volume. The unit volume includes the volume of the dust particles themselves, the pores of the dust particles themselves adsorbed on the surface of the dust particles, the amount of air, and the gap between the dust particles. To clarify the bulk density of dust is of great significance for ventilation and dust removal, because it is closely related to the dust removal performance of dust.

(2) Understand the chemical and physical properties of dust-containing gas, such as moisture content, temperature, chemical composition and properties. The determination of these parameters is directly and indirectly related to dust removal and other treatment measures for selecting filter air speed. If the dust-containing gas contains chemical components, such as chlorides, the chlorides are generally prone to "moisture absorption". If no other measures are taken, the dust bag may "dust".

(3) Understand the particle size distribution of dust. The particle size of dust is its basic characteristic. It is a composition composed of particles of various sizes. It is not sufficient to characterize the aggregate by the average particle size.

(4) Understand the viscosity of dust. The viscosity of dust is a characteristic of mutual attraction between dust or between dust and molecules on the surface of an object. For bag-type dust collectors, the effect of viscosity is more prominent, because the dust removal efficiency and filtration resistance mainly depend on the ability to remove dust from the filter material.

In the design process of the dust collector, other relevant technical parameters cannot be ignored. It is necessary to know that from the current design practice of dust removal equipment in China, it is still very difficult to collect data in the above four aspects comprehensively and accurately.
