The main types of fugitive emission dust in the cement industry are as follows:
Raw material dust
It mainly comes from calcareous raw materials (limestone), silicon-aluminum raw materials (sandstone, clay, fly ash, etc.) and iron raw materials (iron powder, sulfuric acid slag, etc.) into the factory, crushing and pre-homogenization, and the fugitive emissions of such dust account for about 50% of the unorganized emissions of cement enterprises.
Raw meal dust
It mainly refers to the fugitive emission generated in the process of raw material batching, grinding, homogenization and transportation, and the fugitive emission of this kind of dust is becoming less and less with the technological progress of the cement industry.
Fuel dust
It mainly refers to the fugitive emissions generated in the process of coal entering the plant, storage, reversing, crushing, grinding, and transportation, especially the coal dust emissions generated in the process of loading, unloading and reversing.
Clinker dust
Fugitive emissions mainly come from the process of clinker transportation, blanking, and secondary reloading, especially the dust generated by secondary reloading.
Cement dust
Fugitive emissions mainly come from cement packaging, bulk and transportation, especially in the shipping sector.
Due to the complexity of emission sources in the cement industry, if you want to do a good job in the treatment of unorganized emission dust, it is not only a simple treatment of dust, in addition to treatment, but also from the source to suppress and prevent problems in the future, which requires the establishment of a set of real-time dust** In addition, in order to achieve the best treatment effect, enterprises should establish an unorganized emission dust control platform, real-time monitoring, and control and control the dust from the source to reduce pollutant emissions.
According to the characteristics of unorganized dust emissions in industrial and mining enterprises, the integrated platform for fugitive emission control and governance is equipped with intelligent fog cannons, dry fog (cloud) dust suppression systems, various source dust control equipment and intelligent monitoring equipment for fugitive emissions, so as to realize real-time monitoring of fugitive emissions, effectively grasp and scientifically analyze the data such as distribution, concentration, and change law of unorganized emissions, and make treatment measures according to local conditions according to the analysis results. Scientific governance to improve the overall governance efficiency of industrial and mining enterprises and reduce the difficulty of governance control.
