Flue gas desulfurization with pyrolusite
Gas diffusion resistance within the solid particles to accelerate the reaction rate,[link widoczny dla zalogowanych], with high desulfurization rate of the small particle size, but will only increase the power consumption of crushed ore,[link widoczny dla zalogowanych], so in the practical application of a suitable size to operate optional. 1h when the solid ratio: 61; gas superficial velocity: 3.0m/wan; room temperature; speed; 500r/raim imports so, concentration: 30O0 / Wai, 5 ore particle size on desulfurization rate. 5 Yo no rainbow of cushions pan chu _ rd Xiu rate2.5 paid the size of flue gas flow flue gas flow rate of sulfur removal also affected, adjust the gas flow tests were 1.18m3 /,[link widoczny dla zalogowanych], m2 ・ mlni ~ 3 .0 m3 / (m2 ・ rain), 4.37m3 / (I112 ・ rain), 583rn3, ~ 2 ・ rain), study its effect on the desulfurization rate, test results shown in Figure 6 can be seen from the figure, with the smoke gas flow rate increases, the gas jet in the jet pipe faster, even though the unit of time increases the amount of gas into the liquid, but because of the gas in the liquid phase residence time shortened, it is not full and pulp exposure, while the initial the rapid consumption of a large number of so2 slurry, so that the reaction process in the later seems more So2 excessive, resulting in desulfurization rate decreased from 1 hour of sampling and analysis results can be clearly demonstrated that the high gas flow may also cause similar packed column or plate tower operation of the \But the gas flow can not be too small, otherwise it will result in absorption equipment is too large, increase investment costs, so in practice the two effects should be considered, to select a suitable value. Liquid to solid ratio: 6:】; import s02 concentration: 3O00Ill 【: room temperature; speed; 500r/min: ore particle size: 2 (30 mesh 6 Kids in flue gas flow on the desulfurization rate of ng-6Effec ~ offlowI defect of pan the former times I Ⅱ t Xiu Ying rate No. 5 Xiao-Fan Zhu, et al: 26 pyrolusite FGD system level 2.6.1 manganese sulfate manganese leaching rate considering the impact of desulfurization rate and other factors, determine a more appropriate operation conditions and run under these conditions some time after the release of absorbed liquid (soil was yellow), the leaching rate of manganese, the results in Table 2. Table 2, the leaching rate of absorption solution Yue before absorption of manganese absorption rate of threat out of sleep /% the amount of child Plastic 4: Nang equivalent worm worthy:. 0.900. a 5833o. ∞ o7785.6 ore sample number was added the amount of powder / kl1 Club # 063 0.62 Social o62.6.2 refined absorption solution to absorb several groups Liquid merger process in Figure 7, the crude was refined manganese solution. Wataru old plastic solid value _ Health refining process of absorption solution 7, №, 7R songs ag mantis 2.6.3 d song crucian carp through the absorption solution of manganese sulfate product The process of processing the refined, the resulting product -0 (pink), the analysis results with the national standard (GB1622-86) compared in Table 3. Product Analysis showed that the absorption liquid obtained after desulfurization refining through processing, its product quality can meet the national standard. Table 3 Product h6od ・ 0 results 1.3C0nI that bear 0f cricket. * Mary O coffee d3 Conclusion 1) flue gas desulfurization with pyrolusite obvious, can effectively remove smoke S02 () 90%) while absorbing liquid can be resources,[link widoczny dla zalogowanych], manganese sulfate can be used as chemical products, and no secondary pollution to the environment; 2) as the absorption by JBR reactor equipment. Mass effect, pressure drop, equipment, blames bristles, desulfurization efficiency; 3), pyrolusite desulfurization efficiency and liquid to solid ratio,[link widoczny dla zalogowanych], import gas concentration, gas flow and the slag particle size and other factors, by testing and analysis can determine an optimum process operating parameters; 4) obtained after desulfurization absorption solution, processed, refined, you can meet the national product standards.
