The dust removal mechanism of the cyclone is to make the dust-containing gas rotate in the dust collector. The particles in the gas are separated from the airflow by the centrifugal force and separated from the airflow. The dust-containing gas is purified by this way.
The structure of the cyclone dust collector is relatively simple, and is generally manufactured by iron plate welding. There are no moving parts in the equipment, and the production and processing are relatively easy, and the cost is relatively low. Cyclone dust collector is simple, convenient, high temperature resistant, and has good adaptability to high concentration dust. It is the main equipment for controlling small boiler dust pollution. It is commonly used for primary purification of high-concentration dust-containing gases, or as a discharger for powder pneumatic conveying equipment in production.
Since the cyclone dust collector is dust-removed by the gravity of the particles themselves, the dust removal efficiency of the dust particles having a particle diameter of less than 2.5 is extremely low. In fact, it is the dust particles with a particle size of less than 2.5 that are much more harmful to human health and atmospheric environment than large particle dust. These dusts hardly settle in the air by their own gravity, and can be suspended in the atmosphere for a long time, making the city seem to be covered with a gray cover. They are often adsorbed and other harmful gases, and the harm to the human respiratory system is further increased after being absorbed into the human body. When the atmospheric temperature drops, they become condensation nuclei of water vapor, which increases the dense fog in the city. With the development of environmental protection, it is obviously not enough to use only cyclone dust collectors to control soot pollution. However, the application of the mechanism of dust removal by centrifugal force is very wide. Nowadays, the mechanism of using this kind of mechanism together with the alkali-containing aqueous solution to form various types of desulfurization dust remover has become one of the main directions for improving the efficiency of desulfurization and dust removal in China’s environmental protection science and technology community.
