Abstract:
In the production process of industrial water treatment chemicals, According to the production process characteristics and the requirements, SIMATIC S7-300 PLC (programmable logic controller) and some other control elements are used in the mixture controlling of proportioning tank, controlling of pump running or shut down and material liquid transfer. And then the reacting process of feeding, polymerization, keeping temperature, distillation, cooling, neutralization in the polymerization reactor are sequentially controlled. A useful PLC control scheme for the safety measure in case of emergency is given out, The system is save with, high efficiency and low consumption.
