Efficient and environmentally friendly large-scale desulfurization and denitration tower ammonia - ammonium sulfate FGD + Wet Wet ammonia catalytic denitrification desulfurization process is relatively mature, the desulfurization process has been industrialized, washing ammonia absorber flue gas containing sulfur dioxide, a by-product can be used ammonium * agricultural fertilizer, can better meet the needs of the development of flue gas desulfurization, high desulfurization efficiency of this process, it is easy to reach more than 95%. FGD after only low concentrations of sulfur dioxide, smoke and dust content is also greatly reduced. Ammonia is a byproduct of flue gas desulfurization * ammonium, it is China's vast arable land needed for sulfur-nitrogen fertilizer. It can be used alone, or you can do together with other nutrients compound fertilizer, has broad market demand. Not as a by-product of calcium-based desulfurization gypsum or calcium Asia *, or because of market saturation, or because it can not be used after the abandon also occupy valuable land resources, a "stone move" phenomenon. One ton of ammonia can produce more than four tons of ammonium fertilizer * 96%, according to the current price of our research, three t * ammonium fertilizer value can offset the cost of a ton of ammonia, also left a ton of ammonium * become surplus. * If further with ammonium chloride reacted with potassium and ammonium chloride *, value-added products will have improved significantly. Ammonia FGD perfectly suited to national conditions of China's energy, agricultural development and environmental integrated governance. Efficient and environmentally friendly large-scale desulfurization and denitration tower - With China's increasing emphasis on environmental protection, flue gas denitrification system applications has gradually expanded, the current power plant flue gas denitrification system is mainly used in the selective catalytic reduction) flue gas denitrification process, because this process system complex, high investment, high operating costs, so the application subject to certain restrictions, especially small and medium enterprises, but also the inability of SCR equipment, for this situation, my company and brand-name institutions to develop a wet denitration purification equipment, which can effectively control nitrogen oxides, and has invested a small footprint, easy operation and management, and low operating costs. Efficient and environmentally friendly large-scale desulfurization and denitration tower - Principle of magnesium oxide: magnesium oxide and magnesium oxide powder desulfurization first formulated into hot water Mg (OH) 2 slurry was added to the absorption tower, along with the washing cycle absorbed by circulating pump slurry into the tower sprinkler pipe network from the flue gas cleaning of the boiler. Boiler flue gas SO2 reacts with MgO by the oxidation reaction of MgSO3 become MgSO4 solution. Specific reaction is as follows: slurry preparation: MgO + H2O = 2Mg (OH) 2 absorption reaction: Mg (OH) 2 + SO2 → MgSO3 + H2O MgSO3 + SO2 + H2O → Mg (HSO3) 2 Mg (HSO3) 2 + Mg (OH ) 2 → 2MgSO3 + 2H2O oxidation reaction: MgSO3 + 1 / 2O2 → MgSO4 adverse Recycling: MgSO4 + 7 H2O = MgSO4.7 H2O Product Source: www.huaqiang0318.com/huaqiang518-Products-10162868/ desulfurization and denitration Tower Other Products Consulting: www.huaqiang0318.com/huaqiang518-Products-9905165/ tunnel kiln flue gas desulfurization tower
