Lies in choosing the right equipment rotary kiln dust emission characteristics

Currently, the widespread use of lime rotary kiln production industry technology, and contains a lot of dust kiln exhaust gas, will cause serious impact on the surrounding environment. Therefore, an effective dust filter kiln exhaust gas, the protection of the environment is significant. From the practical point of view the current pulse bag filter equipment for its cleaning ability, dust, high efficiency, low emission concentration, stable operation and other characteristics in a rotary kiln system has been widely used. Temperature of the gas to be filtered, Sand-making Line      which contain characteristics of dust, water vapor content and so will the use of bag filters have a greater impact, according to the characteristics of the airflow to a reasonable selection and adjustment, in order to better play the role of baghouse. Rotary kiln exhaust gas is characterized by:. 1, the gas temperature is high Rotary kiln is thermal equipment, to ensure product quality, dust control device inlet airflow temperature is usually around at 1800C 2, dust concentration, corrosion resistance Rotary kiln exhaust gas concentration is usually greater.. than 100mg/m3. Dust particles main ingredient is CaO, MgO particles, soot particles, silicates and iron and aluminum acid particles, which particles of CaO, MgO particles have a strong corrosive. 3, the water vapor content. As the raw material there is in the early stone washing process, large amounts of water attached to the surface of the original stone, so the water vapor content of the gas stream larger.
