Method for capturing CO2 in electrolytic manganese chemical combination workshop and mineralizing electrolytic manganese residues
The invention discloses a method for capturing CO2 in an electrolytic manganese chemical combination workshop and mineralizing electrolytic manganese residues. The method comprises the following steps: conveying the electrolytic manganese residues to a No.1 slurrying reaction kettle, adding water in a set proportion, reacting to obtain filter residues No.1 and filtrate No.1, adding ammonia water, organic amine and an additive in a set proportion into the filtrate No.1, simultaneously introducing CO2 mixed gas, reacting to obtain a product 1 and filtrate 3 #, conveying the filtrate 3 # to a No.2 slurrying reaction kettle, simultaneously adding the filter residues No.1, and reacting to obtain a product 2 #; then adding set ammonia water, organic amine, an additive and an electric field into a No.2 slurrying reaction kettle, then introducing CO2, and reacting under the conditions of set reaction temperature and time to obtain a filter residue 2 # and a filtrate 2 #; and finally, recycling the filter residue 2 #, adding the filtrate 2 # into a MnSO4 solution, reacting to obtain a product 2 and a (NH4) 2SO4 solution, and treating the (NH4) 2SO4 solution with an MVR (mechanical vapor recompression) technology to obtain a filtrate 4 #, and recycling the filtrate 4 # in an electrolytic manganese workshop. The filter residue 2 # water washing liquid can be recycled to the 2 # slurrying reaction kettle, and the MVR evaporation liquid can be recycled to the 1 # slurrying reaction kettle.
本发明公开了一种捕集电解锰化合车间CO2及矿化电解锰渣的方法。步骤如下：将电解锰渣输送到1#号浆化反应釜，加入设定比例的水，反应后得到滤渣1#和滤液1#，向滤液1#中加入设定比例的氨水、有机胺，添加剂同时通入CO2混合气体，反应后可得到产品1和滤液3#，将滤液3#输送到2#号浆化反应釜，同时加入滤渣1#，随后在2#号浆化反应釜加入设定的氨水、有机胺、添加剂和电场后，再通入CO2，在设定的反应温度和时间条件下反应后得到滤渣2#和滤液2#。最后，滤渣2#可资源化利用，滤液2#加入MnSO4溶液反应后可得到产品2和(NH4)2SO4溶液，(NH4)2SO4溶液通过MVR技术后可得到滤液4#循环利用到电解锰车间；滤渣2#水洗液可回用至2#号浆化反应釜，MVR蒸发液可回用至1#号浆化反应釜。
