| titleOfInvention | Method for mass production of phosphoric acid with rotary kiln |
| abstract | A method for mass production of phosphoric acid with a rotary kiln, comprising the following steps: pretreating raw materials a carbonaceous reductant; preparing the pre-treated carbonaceous reductant powder; then evenly mixing the carbonaceous reductant powder and the silica powder to obtain a cladding material; mixing the cores and the cladding material for cladding treatment, drying and solidifying same to obtain composite pellets; sending the composite pellets into a rotary kiln for a reduction reaction; sending the high-temperature slag balls exiting the rotary kiln to a cooling device for comprehensive utilisation; introducing the fume containing P 2 O 5 and fluorine exiting the kiln into a hydration tower for absorbing phosphorus by hydration, then passing same through a phosphoric acid mist capturing tower and a mist removing and separating tower successively, and the fluorine-containing fume discharged from the mist removing and separating tower entering a subsequent fluorine recovery procedure. |
