1. The working principle of cyclone bag filter:
When the dust is drawn into the cyclone dust collector by the centrifugal fan, it will rotate from top to bottom along the wall. Therefore, the dust particles are separated from the airflow by centrifugal force, and then fall into the ash hopper along the wall by gravity, and the gas will be discharged from the discharge pipe upwards along the discharge pipe. The cyclone dust collector is a dry filter dust collector.
2. The structure of the cyclone bag filter:
The cyclone bag filter is composed of intake pipe, exhaust pipe, cylinder, cone and 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 ordinary 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% was successfully developed. Among mechanical dust collectors, cyclone dust collectors are the most efficient. It is suitable for the removal of non-sticky and non-fibrous dust, and is 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. In terms 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).
