The dust collector of an organic fertilizer production line is mainly used to collect dust to reduce dust emissions. In organic fertilizer production, it is generally set in the drying link after granulation of the organic fertilizer production line. The dust collector is a dust removal device that separates the dust generated in industrial production from the flue gas. So how to choose a dust collector?

1. Understand the bulk density or bulk density of the dust, that is, the amount of dust per unit volume. The unit volume between them includes the volume of the dust particles themselves, the micropores of the dust particles adsorbed on the outside of the dust particles, the air volume, and the gaps between the dust particles.

2. The performance of the dust collector is expressed in terms of the amount of gas that can be processed, the resistance loss of the gas passing through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance cost, service life, and operation and management difficulty of the dust collector are also important factors to consider its performance.

3. To understand the particle size distribution of the dust. The particle size of the dust is a characteristic of its root and bottom, and is composed of particles of different particle sizes. It is impossible to simply characterize this aggregate with a uniform particle size.

4. Understand the viscosity of the dust. Viscosity is the property of mutual attraction between dust or dust and external molecules of an object. The effect of viscosity on bag dust collectors is more prominent, because the dust removal capacity and filtration resistance depend largely on the dust removal capacity in the filter medium.

5. Understand the chemical and physical properties of dust-laden gas, such as water content, temperature, chemical composition and properties. The determination of these parameters is directly related to the additional treatment of dust removal and the selection of filtration wind speed. If some dusty gases are rich in chlorides and other chemical components, then chlorides are usually easy to "absorb moisture". If other methods are not adopted, it will cause the dust bag to become a "sticky bag".
