| titleOfInvention | Continuous clean system of phosphoric acid |
| abstract | The invention belongs to the field of phosphoric acid preparation, and particularly relates to a continuous phosphoric acid purification system.A phosphoric acid inlet is formed in the upper end of an acidolysis tank, the lower end of the acidolysis tank is connected with a section of neutralization tank through a pipeline, and a calcium carbonate feeding port is formed in the upper end of the section of neutralization tank; the lower end of the first section of neutralization tank is connected with the first section of separator through a pipeline; the lower extreme of one section separator is (fertilizer level) calcium hydrogen phosphate thick liquid export, and one section separator upper portion is provided with upper clear liquid pipe, puts into two-stage process and pond through upper clear liquid pipe with the clear liquid, and two-stage process and pond upper end are provided with the lime breast charge door, and there is two-stage process separator two-stage process and pond tail end through pipe connection, and the thick liquid of two-stage process separator passes through the pipe-line transportation to the acidolysis pond in, and the upper clear liquid of two-stage process separator is phosphoric acid after purifying. The utility model discloses can realize energy saving 20%, the yield improves more than 5%. Meanwhile, the thick slurry in the second section is returned to be dissolved, so that the whole purification yield is improved, and no waste is discharged. |
