Study on desulphurization technology of ballast crushing technology, from the beginning of the century it has been 90 years of history. These techniques are summed up can be divided into three categories: pre combustion ballast crushing, combustion ballast crushing (sulfur) and after combustion ballast crushing (FGD). Pre combustion ballast crushing technology is coal preparation technology, divided into physical method, chemical method and biological method.
The physical coal cleaning technology is applied in the world before combustion ballast crushing technologies most widely, the method can be clay, shale and pyrite sulfur removal from raw coal. The physical method has the advantages of simple process, low investment, low operation cost, but the organic sulfur removal from coal ballast crushing can not, of pyrite sulfur rate of only about 50%.Most of the chemical ballast crushing of organic sulfur in coal, the main use of different chemical reactions, including bio chemical reaction of sulfur in coal, will change because of the separation into different forms of sulfur.
Red mud processing production line requirements more strict, in fact, red mud treatment process is relatively complex. Microbial ballast crushing technology is the coal powder suspended in the air bubble liquid containing bacteria, the bacteria produce enzymes that promote oxidation sulfur into sulfate, to achieve the purpose of ballast crushing. This kind of technology has its advantages, but now in the laboratory stage, there are still some distance away from the industrial application. birder2525 mary / Mining & Crushing Equipment |
