Phosphoric acid production system, including a thermal process phosphoric acid production line, characterized in that: it also includes a DCS system;
Said DCS system is connected to the thermal process phosphoric acid production line to control phosphoric acid production process parameters. In order to solve the technical problems that the existing thermal process phosphoric acid production line has a large amount of control of process parameters, human control is prone to errors, and the product quality is not stable, a new type of thermal process phosphoric acid production system is disclosed.
The technical solution adopted by the present invention to solve the above technical problems is: a new type of phosphoric acid production system, including a pyrophosphoric acid production line, a DCS system; said DCS system is connected to the pyrophosphoric acid production line to control the phosphoric acid production process parameters.
The beneficial effect of the present invention is that it improves the detection precision and control precision of the process parameters, reduces labor intensity, overcomes the influence of human factors on product quality, reduces the incidence of accidents, and realizes the automatic control of the key processes in the production of pyrophosphoric acid. The technical solution of the present invention is mainly used for the transformation of the existing thermal process phosphoric acid production line.
