The heat utilization rate has been significantly improved, but the first three items still account for 84.65%, and the heat of the flue gas and the heat taken away by the finished product are higher than those of the small kiln with a diameter of φ1600 in the 1980s. This is mainly due to the high tail temperature of the current operating process (380 ~ 400℃), due to the large output

Description
technical field [0001] The invention relates to a treatment device for by-products in the preparation of titanium dioxide, in particular to a device for producing granular ferrous sulfate. Background technique [0002] Titanium dioxide (English name: titanium dioxide), the main component is titanium dioxide (TiO 2 ) of white pigment. Scientific name: titanium dioxide (titanium dioxide), molecular formula is TiO 2 , is a polycrystalline compound whose particles are arranged regularly and has a lattice structure. Titanium dioxide is a white pigment widely used in coatings, chemical fibers, rubber, enamel, ceramics, plastics, papermaking, printing inks, electronic ceramics, glass, welding rods, cosmetics and other industries. [0003] Ferrous sulfate is a by-product of sulfuric acid production of titanium dioxide, and the by-product of titanium dioxide production, ferrous sulfate heptahydrate, has become a heavy burden on the sulfuric acid titanium dioxide industry. The by-...
