What is the dedusting mechanism of cyclone? What are the advantages and disadvantages?
February 17th, 2022
Cyclone dust collector is a kind of dust removal device. The dust removal mechanism is to make the dusty air flow rotate, separate the dust particles from the air flow and trap them on the wall with the help of centrifugal force, and then make the dust particles fall into the ash hopper with the help of gravity. Each component of the cyclone dust collector has a certain size proportion. The change of each proportion relationship can affect the efficiency and pressure loss of the cyclone dust collector. Among them, the diameter of the dust collector, the size of the air inlet and the diameter of the exhaust pipe are the main influencing factors.
Cyclone dust collector is composed of air inlet pipe, exhaust pipe, cylinder, cone and ash hopper. Cyclone dust collector has the advantages of simple structure, easy manufacture, installation, maintenance and management, low equipment investment and operation cost. It has been widely used to separate solid and liquid particles from gas flow or solid particles from liquid. Among the mechanical dust collectors, cyclone dust collector is the most efficient one. It is suitable for the removal of non viscous and non fibrous dust, mostly used to remove 5 μ Particles above M, parallel multi tube cyclone device pair 3 μ M particles also have a dust removal efficiency of 80 ~ 85%. The cyclone dust collector constructed of special metal or ceramic materials resistant to high temperature, abrasion and corrosion can be used at temperatures up to 1000 ℃ and pressures up to 500 ℃ × Operate at 105Pa. In terms of technology and economy, the pressure loss control range of cyclone dust collector is generally 500 ~ 2000Pa. Therefore, it is a medium efficiency dust collector and can be used for the purification of high-temperature flue gas. It is a widely used dust collector. The main disadvantage is that it can remove small dust particles (< 5%) μ m) The removal efficiency of is low.
