Magnesium oxide for desulfurization, magnesium oxide for mould shell and magnesium oxide for firecrackers?
Yingkou Hexiang has been engaged in fire-resistant industry for more than 30 years. The product quality is superior, and the products are sold all over the country.
The principle of magnesium oxide desulfurization in power plants is introduced: the basic principle of magnesium oxide desulfurization in power plants is to absorb SO2 with MgO slurry to produce hydrated magnesium sulfite and its magnesium bisulfite. Magnesium sulfite is the main metabolite of desulfurizer in this process, and reacts with sulfur dioxide to produce magnesium bisulfite. Magnesium bisulfite reacts with newly added magnesium oxide to form hydrated sulfite. Magnesium, therefore, is recycled as the intermediate product in the whole reaction process. Magnesium sulfite is the main metabolite of the reaction. Magnesium sulfite and magnesium bisulfite are the main metabolites. Some oxidation products contain magnesium sulfate. The so-called crystallization is a metabolite precipitated in the desulfurization reaction process when the desulfurization circulating liquid reaches saturation or supersaturation. Any desulfurizer will produce desulfurization products. No crystallization process is not a complete operation of desulfurization technology. However, how to make the desulfurization products not crystallize or delay crystallization in the process of circulating liquid? First, desulfurization should follow the PH value not more than 6.8. Generally, the PH value is between 5.5 and 6.2. According to the sulfur content of raw coal, sometimes it will be reduced. That is, desulfurization of circulating liquid under acidic conditions, it is difficult to form polycrystallization of alkaline sulfate substances under acidic conditions, even in excessive conditions. There are crystalline substances in saturated state, and most of them will precipitate together with the removed dust, which will be salvaged with the dust in the sedimentation tank. Turbine super-strong turbulence technology is used. Not only is there no crystallization blockage in the reformed desulfurization tower, but it can almost avoid the phenomenon of crystallization blockage. There is no nozzle in the turbulence tower, and the circulating liquid flows directly from the straight pipe, such as the inner part of the tower. Therefore, the "nozzle problem" which is most easily blocked in the desulfurization process is solved thoroughly.
