The nature of the dust has a great influence on the technology and design of the dust collector. For some special properties of the dust, effective measures must be taken according to the design experience.

(1) Adhesion and cohesion. Adhesive and cohesive dust enters the dust collector, and the dust particles will become larger after agglomeration. The dust accumulated on the surface of the filter element can continue to condense during the process of being shaken off. The dust removal efficiency and the dust passing through the filter material The amount is also related to the adhesion and cohesion of dust. Therefore, when designing dust with very significant adhesion and cohesion, or dust with almost no adhesion and cohesion, it must be different according to the type of dust and the purpose.

(2) Particle size. The main influence of particle size distribution on the dust collector is resistance loss and wear. Fine dust has a greater impact on pressure loss, and coarse dust has a decisive effect on wear, but only particles with high dust concentration and high hardness at the inlet have a greater impact.

(3) Particle shape. It is generally believed that needle-shaped crystal particles and flake-shaped particles are likely to block the pores of the filter material and reduce the dust removal efficiency. The fibrous particles that can agglomerate into flocs are difficult to fall off the surface of the filter material if the filter speed is high. Different filter wind speeds are selected according to the particle shape and characteristics.

(4) The density of particles. The bulk density of dust is related to particle size, cohesion, and adhesion, as well as the resistance loss and filter area of the filter element of the dust collector. The smaller the bulk density, the more difficult it is to clean the dust. The design should choose a lower filtration wind speed. In addition, the bulk density of dust is critical to the capacity of the selected dust collector.

(5) Hygroscopicity and deliquescent. Dust with strong hygroscopicity and deliquescence, during the operation of the dust collector, it is easy to absorb moisture and solidify on the surface of the filter material, or it will deliquesce and become a thick substance when it meets with water, causing difficulty in cleaning dust, increased equipment resistance, and even impact The dust collector is operating normally.

(6) Static electricity. Once the easily charged dust generates static electricity on the filter material, it is not easy to fall off. For the very easily charged dust, technical measures such as anti-static filter material must be adopted to avoid explosion caused by sparks caused by static electricity.

(7) Flammability. For combustible dust, although it does not necessarily cause an explosion, if sparks appear in the process before the dust collector and can enter the dust collector, explosion-proof measures should be adopted, such as the addition of spark traps and explosion-proof doors.
