Intelligent on-line medicament adding system

Abstract

The invention belongs to medicament adding technical field, and concretely relates to an intelligent on-line medicament adding system. The system comprises a medicament storage device, a medicament adding pipeline and a control system. The system is characterized in that the medicament adding pipeline includes a medicament conveying pipeline, and the medicament conveying pipeline is provided with a metering pump for adjusting the medicament conveying amount, a PH meter for monitoring PH values and a plurality of valves for controlling the pipeline to be on and off; and the control system includes a PLC core controller, a PID digital-analog controller, a GPRS module, a switch and a DCS controller. On-line acquired analog quantities such as a PH value, a liquid level, flow and temperature are taken as feedback values, a PID mathematic model is established, a fuzzy adaptive control algorithm is optimized, a diagnosis system is established, the medicament adding amount is calculated, then control data is input to the metering pump, and thus the adding amount of medicaments is controlled accurately.

Description

technical field [0001] The invention belongs to the technical field of dosing, and in particular relates to a complete device capable of intelligently controlling the addition of medicinal liquid on-line, and an intelligent on-line dosing system. Background technique [0002] The dosing equipment is designed according to different processes, precisely configures the solutions of various chemicals, and then accurately doses them with metering pumps to meet various design requirements, such as descaling, oxygen removal, coagulation, acid addition, alkali addition, etc. At present, the automatic dosing devices used in industries such as power plants, pharmaceutical factories, chemical plants, and sewage treatment plants generally have problems such as single parameters, inability to monitor and maintain in real time, and so on. Technology, providing water treatment system solutions with high standards as the product design idea, designed an intelligent online dosing system with...
