The conventional operation is to add acid into the circulating water to adjust the alkalinity and the pH value, add scale inhibitor to inhibit scale and add corrosion inhibitor to prevent the corrosion of the system. Usually, acid, scale inhibitor and corrosion inhibitor are added in a fixed amount, the reaction on the change of the water quality of circulating water make-up water is slow, and the dosage cannot be adjusted in time, so that the problems of scaling and corrosion of a system are caused.
The water quality of the existing circulating water is manually tested in a laboratory, and the control mode of the circulating water is adjusted according to the test result. The manual test cannot timely reflect the water quality change of the circulating water make-up water, so that the control of the circulating water is delayed. Once the condition of water quality mutation of circulating water make-up water occurs, the supervision means cannot react in time, and the test result of a laboratory needs to be fed back to an operator to adjust and change the dosage.
Therefore, a real-time automatic control system for circulating water needs to be developed, which can timely adjust the dosing amount of the circulating water and ensure the stable operation of a circulating water system.
