| titleOfInvention | Comprehensive utilization method for solid wastes and waste acid in production process of titanium dioxide |
| abstract | The invention discloses a comprehensive utilization method for solid wastes and waste acid in the production process of titanium dioxide. The comprehensive utilization method comprises the following steps of: firstly, respectively treating acidolysis waste slag, ferrous sulfate and calcium sulfate dehydrate which are generated in the production process of the titanium dioxide by adopting a sulfuric acid method through drying, crushing and other methods for later use; secondly, uniformly mixing 70-80 parts by weight of iron pyrite, 1-10 parts by weight of acidolysis waste slag, 1-5 parts by weight of ferrous sulfate and 1-10 parts by weight of calcium sulfate dehydrate to obtain raw ore for producing sulfuric acid, calcining the raw ore in a fluidized bed furnace to obtain furnace gas meeting the production requirement of the sulfuric acid, carrying out purification procedures such as cooling, dust removal and dehydration on the furnace gas obtained in the second step and then converting and absorbing the treated furnace gas by adopting a catalyst to obtain the sulfuric acid. According to the comprehensive utilization method disclosed by the invention, wastes generated in the production process of titanium dioxide are reasonably utilized and the recycling of resources is realized. |
