Intelligent digital management system and method for circulating cooling water

Abstract

The invention provides an intelligent digital management system and a method for circulating cooling water. The intelligent digital management system comprises a circulating water pretreatment device, a non-phosphorus scale inhibitor dosing device, a non-oxidation dosing device, a chlorine dioxide generation dosing device, a sulfuric acid dosing device, a bypass flow filtering device and an intelligent data center. The intelligent data center analyzes monitoring data of all the devices and dynamically adjusts the medicine adding amount, intelligent medicine adding and automatic pollution discharging are achieved, the operation cost is saved, when a fault occurs, firstly, the intelligent data center conducts mutual calibration of all instruments and gives an alarm for an abnormal instrument, and if the water quality of supplementary water is abnormal, the intelligent data center gives an alarm for the abnormal instrument. And the intelligent data center gives an alarm according to a matched instrument, and feeds back, calculates and adjusts other dosing amounts and valves to realize dynamic balance.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an intelligent digital management system and method for circulating cooling water. Background technique [0002] In recent years, thermal power plants, as large water consumers, have experienced a sharp increase in water resource constraints and discharge restrictions. Among them, the amount of water used and discharged by the circulating water system accounts for 80% to 90% of the total water consumption and total discharge of circulating cooling thermal power plants. focus. At present, most circulating cooling power plants have increased the concentration ratio by strengthening raw water pretreatment, optimizing water stabilizers, and upgrading condenser pipes; circulating water and sewage are reused as water for desulfurization, coal transportation, and slag removal, but there are still a large number of The remaining circulating water sewage needs to be discharged o...

AI Technical Summary

Problems solved by technology

[0005] The present invention is to solve the problem that the circulating cooling tower cannot accurately add medicine and control the water quality, and provides a circulating cooling water intelligent digital management system and method. The intelligent data center dynamically adjusts the dosing amount by analyzing the monitoring data of each instrument. Realize intelligent dosing and automatic sewage discharge, save operating costs, and when a failure occurs, the intelligent data center will first calibrate each instrument and give an alarm to the abnormal instrument. Alarm, and at the same time feed back calculations to adjust other dosing volumes and valves to achieve dynamic balance
