| titleOfInvention | Phosphoric acid fertilizer manufacturing method using incineration ash and its manufacturing apparatus |
| abstract | Provided are a method and apparatus for producing a stable phosphate fertilizer at low cost by adjusting a change in the content of the phosphorus component. n Sludge sludge ash is used as a main raw material, and secondary raw materials such as magnesium, calcium, and potassium are added and heated in a melting furnace to separate molten metal and molten slag, and then the molten slag is discharged and quenched to produce phosphate fertilizer. The calculation device obtained by analyzing the total phosphoric acid concentration of the sludge incineration ash, which is the main raw material, to calculate the fluctuation, and after determining the total phosphoric acid concentration in the incineration ash, calculating the addition ratio of the high phosphorus-containing waste in the secondary raw material; It is equipped with the addition apparatus which adds sub raw materials, such as high phosphorus containing waste, with respect to a main raw material according to the phosphoric acid concentration previously determined by the output of an arithmetic unit. n n Sludge, incineration ash, melting furnace, slag, exhibit, phosphoric acid concentration, waste, phosphorus containing, fertilizer |
