Detailed Product Description: | FH-101 composite cryogenic liquid phase desulfurization and denitration Wuhan Germany has developed a world environmental flue gas desulfurization and denitration agent, a desulfurization unit can be completed at a low temperature ionic liquid phase oxidation of the wet conditions. Denitration, namely catalytic oxidation NO , NO2, ion exchange N2 adsorption SO2. Improve equipment utilization and cost saving investment, a desulfurization unit and also the removal of NOX, reach for the removal of nitrogen oxides to achieve desulfurization and denitration of dual purpose, to smoke emission standard completely. Research Motivation: Based on the status denitration technology, research sulfur, nitrogen oxides, and the law has developed a way to at low temperatures, the formation of a liquid state catalytic oxidation desulfurization and denitrification technology, using ion catalyzed oxidation / reduction and adsorption and desorption constitute liquid desulfurization and denitrification. Nitric oxide does not dissolve in the liquid, must be approved by Jue oxidation can be transformed. Nitrogen dioxide is dissolved in liquid, only partially dissolved, subject to re-redox catalysis. The study found that the catalytic oxidation by (NO) 2 laminated reactive, the reaction rate is slow, slow down the overall reaction time. To this end, the development of a certain proportion of more complex transition metal catalyst at 600 ℃ ~ 800 ℃ conditions, chemically processed physically prepared, to form an ion catalyst solution. Then by adding chemical processing, synthesis of desulfurization and denitration original liquid products. Recycling technology: desulfurization and denitration reaction liquid reaches the end of the ion catalyst deactivation, preclude separation after settling with bottom discharge replacement and regeneration * approach. Catalyst cycle of re-use. Achieve continuous removal of sulfur and nitrogen oxides purposes. Its core technology is processing a variety of metal ions through the complex by chemical synthesis and regeneration of the chemical reaction it restored. Ion in solution to form a continuous desulfurization and denitrification reaction reacts with SO2, NOx, generate sub * salt and N2. Catalyst settlement aggregation. First Asian * replacement, to form gypsum and water, as a supplement to water recycling. Ion solution regenerated catalyst aggregation after repeated use. Thus, the recycling of resources. Change Limestone - gypsum wet desulphurization fouling, blocking and other technology. Reduction (SCR) DeNOx catalyst solid blockage, leakage of ammonia and environmental secondary pollution. FH-101 technical advantages: liquid desulfurization and denitrification process route of new technology; (1) ion desulfurization and denitration liquid SO2, NOx catalytic oxidation / reduction reaction method. (Always is a liquid, the density change) (2) for the column discharge saturated liquid rich catalytic oxidation / regeneration reaction method. (Always liquid, regeneration *) wide (3) temperature range, and SO2, NOx low reaction temperature between 25 ℃ ~ 250 ℃. (4) No need for FGD desulphurization clogging, scaling worry, they do not escape for SCR DeNOx ammonia, smoke blockage and subsequent equipment corrosion bill. SO2, NOx reaction: SO2 in the flue gas is first dissolved in liquid, then dissociate into H + and HSO3-: liquid SO2 dissolved when required under liquid conditions for SO2 ionization reaction in the liquid phase, ionic absorption, Asia * salt compounds generated. NOx oxides collectively have N2O, NO, NO2, N2O3, N2O4, N2O5, and the average percentage by volume concentration of 3 × 10-9. Produced by high-temperature combustion boiler combustion air and coal-fired generating NO in N2 at high temperature and oxygen compounds, low NOx content in flue gas and oxygen content than parts per million, so 90% of the flue gas to form NO. NO can not be acid or base to form a salt, must be ion catalyst Jue oxidation promoting NOx to N2. Reaction: NO + xO2 → NO2 (x patented ingredient) NO2 + H2O → HNO3 + NO NO2 + H2O → HNO2 NO2 + HNO2 → xHNO3 + N2 ↑ 4NO + xO2 + 2H2O = 2NO + 2NO2 + 2H2O = 4xHNO2 2NO + xO2 + 4SO2 = 2NO2 + 4SO2 = 4xSO3 + N2 ↑ denitrification technology due to chemical reaction conditions are relatively complex, requiring catalytic oxidizer within a certain temperature range denitration. Proven, liquid denitration agent between 25 ℃ -250 ℃ apply. The higher the concentration, the higher its relative NOx removal rate. NOX associated temperature and pressure, so the device is designed with certain requirements. Therefore, we have adopted a dual catalytic oxidation technology, according to the chemical reaction conditions of sulfur oxides and nitrogen oxides, sulfides to reduce the competitive effects of nitrogen oxides, lower against the effect of enhancing additive, developed a variety of transition metal ions Jue oxidant balance competing reactions of sulfur and nitrogen, the maximum range of the nitrogen oxides react preferentially improve efficiency double off. Desulfurization and denitration tower combination of design, features such as built-filler, with a smaller amount for ensuring liquid-gas SO2 conversion rate 95% ~ 98%, NO conversion rate of 75% to 85%.
