The specific control process is as follows:
first, the original parameters of the controller 3 are set, and the original parameters generally include: concentration multiple range, conductivity range, dosing pump, chloride ion concentration range, dosage per hour and the like;
then the controller 3 controls the opening of the adjusting valve 6 according to the concentration multiple or the data of the conductivity probe 4 to control the sewage discharge speed, and controls the dosing mechanism 2 to start and stop the dosing pump according to the concentration multiple. The dosing mode is set according to different cooling water agents. For example, the dosage of the slow-release scale inhibitor needs to be controlled according to the system sewage discharge amount, and the dosage of the bactericide needs to be controlled according to the system circulation amount. The automatic chemical feeding device does not need manual start-stop operation, automatically feeds chemicals according to different chemicals, and has more reasonable chemical feeding amount and stable water quality index.
Conductivity control, which controls the regulating valve 6 mainly by comparing the conductivity value with the user set value. When the conductivity value in the water treatment tank 1 is lower than the lower limit value set by a user, the regulating valve 6 is automatically opened to carry out sewage discharge operation, and when the conductivity value reaches the upper limit value set by the user, the controller 3 controls the regulating valve 6 to automatically close to stop the sewage discharge operation.

And the chloride ion control is mainly used for controlling the regulating valve 6 by comparing the difference between the chloride ion value and a user set value. When the chloride ion value in the water treatment pool 1 is lower than the lower limit value set by a user, the controller 3 controls the regulating valve 6 to be automatically opened for sewage disposal operation, and when the chloride ion ratio reaches the upper limit value set by the user, the controller 3 controls the regulating valve 6 to be automatically closed to stop the sewage disposal operation.

The concentration factor is controlled (concentration factor = make-up water/sewage), the make-up water amount is monitored by the first flowmeter 8, and the sewage discharge amount is monitored by the second flowmeter 5. The control of the regulating valve 6 is mainly carried out by comparing the real-time value of the concentration times with the set value. When the concentration multiple ratio is lower than the lower limit value set by the user, the controller 3 controls the regulating valve 6 to be automatically opened for sewage disposal operation, and when the concentration multiple ratio reaches the upper limit value set by the user, the controller 3 controls the regulating valve 6 to be automatically closed to stop the sewage disposal operation. The valve opening amount or flow value can be set in detail through a touch screen or an upper computer (computer).
