Problems solved by technology

[0002] At present, desalinated water equipment has been gradually approved, especially in the improvement of coastal saline-alkali land, reverse osmosis membranes are used to desalinate the brackish water in saline-alkali land, and the desalinated water is used in soil improvement. The existing desalinated water equipment is being carried out In seawater desalination or brackish water desalination, the pH test of the product is carried out regularly or irregularly, and the staff judges the desalination effect through the analysis of the test results. The workload is heavy, time-consuming and laborious, and someone needs to be on duty 24 hours a day

Abstract

The invention provides a pH detection control system of a brackish water desalination device. The system comprises an operational amplifier UA, an operational amplifier UB, an operational amplifier UC, an operational amplifier UD, a photoelectric coupler IC1, a photoelectric coupler IC2 and resistors and capacitors which are connected by wires; and the in-phase input end of the operational amplifier UA is connected with the resistor R2, the capacitor C2 and the resistor R1 in sequence, that is to say, one end of the resistor R2 is connected with the in-phase input end of the operational amplifier UA, the other end of the resistor R2 is connected with the capacitor C2, and the other end of the capacitor C2 is connected with one end of the resistor R1. The inventive system can perform real-time detection of water produced from desalination of the device, can effectively control normal operation of the water desalination device through adjust and control via circuits, save manpower and reduce labor intensity, and has no need of 24-hour artificial guarding; and the circuit is good in voltage and current stabilizing effect, can resist impulse voltage and current of + / -200%, the regulation accuracy is high, and the pH value accuracy can be adjusted to 0.01.
