The cyclone dust collector is composed of an intake pipe, an exhaust pipe, a cylinder, a cone and an ash hopper. The cyclone dust collector is simple in structure, easy to manufacture, install, maintain and manage, and has low equipment investment and operating costs. It has been widely used to separate solid and liquid particles from airflow or to separate solid particles from liquid. Under normal operating conditions, the centrifugal force acting on the particles is 5 to 2500 times that of gravity, so the efficiency of the cyclone dust collector is significantly higher than that of the gravity sedimentation chamber. Based on this principle, a cyclone dust removal device with a dust removal efficiency of more than 90% has been successfully developed. Among mechanical dust collectors, cyclone dust collector is the most efficient one. It is suitable for the removal of non-sticky and non-fibrous dusts, mostly used to remove particles above 5μm. The parallel multi-tube cyclone dust collector device also has a dust removal efficiency of 80-85% for 3μm particles.
The cyclone dust collector constructed of special metal or ceramic materials that is resistant to high temperature, abrasion and corrosion can be operated at a temperature of up to 1000°C and a pressure of up to 500×105Pa. Considering from the aspects of technology and economy, the pressure loss control range of cyclone dust collector is generally 500～2000Pa. Therefore, it belongs to the medium-efficiency dust collector and can be used for the purification of high-temperature flue gas. It is a widely used dust collector and is mostly used in boiler flue gas dust removal, multi-stage dust removal and pre-dust removal. Its main disadvantage is the low removal efficiency of fine dust particles (<5μm).
The cyclone dust collector is one of the most economical dust removal methods. The principle is to use rotating centrifugal force to separate dust and gas. Its filtration efficiency is about 60%-80%. The cyclone dust collector has the advantages of small wind loss, low investment cost, and convenient manufacturing and installation. Generally, it is the first-stage treatment when two-stage dust removal is required when the dust is large.
