Detailed Product Description: | Preparation of manganese slag calcined manganese sulfate FGD / manganese pilot reports a pilot background, manganese slag waste can be used as cement-coagulation agent resource utilization 2, electrolytic manganese dioxide in the flue gas produced by the calcination residue to be treated. 3. Verify that the National Engineering Research Center of FGD's "+ carbon catalytic desulfurization of manganese deep desulfurization," "deep dip manganese" desulfurization manganese leaching test target a new process, to carry out the oxidation of manganese FGD experiments, the flue gas through sulfur dioxide concentration after desulfurization absorber 1000ppm 2, using the anolyte with slurry, slurry discharged desulfurization absorber manganese leaching rate of 85%, after the second dip, manganese leaching rate of 93% 3, desulfurization leaching solution after purification electrolysis meet requirements leaching solution EMM EMM can meet quality requirements of the country in a pilot job content, manganese oxide slurry flue gas desulfurization (1) to carry out the different concentrations of sulfur dioxide in the flue gas desulfurization manganese leaching test. Different concentrations of sulfur dioxide by leaching manganese desulfurization test, to establish the correspondence between the different desulfurization and leaching manganese dioxide concentrations, in order to determine the amount of absorption tower foundation. (2) to simulate liquid flow direction and manganese leaching effect of different desulfurization absorber to verify the feasibility of the process. (3) on an experimental basis in the verification process, continuous feed slurry desulfurization grade test, inspect the system in case of a continuous feed desulfurization relationship with leaching manganese. Second, the depth of the dip and even manganese and manganese sulfate to eliminate two desulfurization slurry after the test to adjust the acidity and temperature, depth manganese leaching test, while the second study of manganese sulfate even eliminated. Third, the leaching solution purification and electrolysis test (1) according to the existing manganese plant purification steps and requirements for desulfurization slurry purification, purified leachate reached the indicators of electrolytic manganese plant leachate requirements. (2) by electrolytic manganese plant in the existing process for desulfurization leachate electrolysis investigated desulfurization leachate EMM situation. Desulfurization Pilot Summary 1, anolyte slurry was made of manganese and South Africa desulfurization, desulfurization by five successive absorption tower, it is possible to achieve desulfurization tower exit gas sulfur dioxide concentration is below 1000ppm of claim 2 through 5 desulfurization, leachate the concentration of manganese ion concentration can meet the requirements of manganese and manganese leaching rate of desulfurization process can reach 93% of the three, even two manganese sulfate leach solution even eliminate trial of two concentrations of manganese sulfate 1.92g / L, lower than even disulfated Manganese manganese content in 5g / L following requirements such as temperature and pH conditions in the industrial process operations, and even two concentrations of manganese sulfate will be lower. Conclusion 1, anolyte and South Africa manganese ore slurry made of desulfurization, by absorbing five desulfurization tower, manganese absorption liquid purification system is feasible overall process: 2, slurry with anolyte and made South Africa manganese desulfurization, by absorbing five desulfurization tower desulfurization tower to achieve the requirements of the export of sulfur dioxide concentrations below 1000ppm, and through the subsequent catalytic desulfurization tower charcoal, sulfur dioxide concentration in the flue gas outlet can reach 100mg / m3 requirements. 3, by the depth of immersion, manganese ion concentration of 50g / L, total Mn slag leachate extraction rate up to 93%. The residue of acid leaching into the plant system to meet the slag manganese content of less than 3%. 4, the slurry after the desulfurization dithionic acid manganese content in 2g / L or less, lower than the control standard 5g / L of manganese electrolyte. 5, desulfurization leachate through improved purification methods, electrolysis neutral liquid purified well electrolytic manganese metal out, manganese quality can meet the national standards |
