Circulating Water Treatment Automatic Dosing Device Monitoring Technology Research

Now, lack of resources and environmental degradation problems have become increasingly prominent, water conservation has become a grim task that every country will be faced.Circulating cooling water for the blood of industrial enterprises, accounting for industrial water consumption of 70%. But its repeat cycle of a low utilization rate, emissions created by the waste and pollution is widespread.In comparison with foreign countries, China's Circulating Water treatment technology is relatively backward, especially those of the mature, Pharmacy prescription excellent programs and automatic control technology combining the research and application is still in the infancy stage.Based on SCM,PLC,the computer automatically drugging and monitoring system in the country has begun to use, but they belong to indirect control, with a certain algorithm is derived by adding various pharmaceutical amount,not real,Online aware of the pharmaceutical circulating water content, increase the accuracy of drug and uniformity can not be guaranteed. excessive or deficient amount Drugging was difficult to avoid.Using fluorescence measurement technology, Experimental methods to the choice of fluorescent tracer type water treatment agent and evaluate their applicability to the detection signal, proved to direct fluorescence measurement technology to accurately detect circulating water content of the idea of Pharmacy, clear water concentration of direct control object to the development of the automatic drug devices technical routes.This article focus on the research and development Circulating Water of drug treatment automatic control device tasks, describes the microcontroller core for signal processing modules, and the choice of single chip microcontroller control system design process. Circuit design including hardware and software design; exposition of the system control method of choice, identified in line with the requirements of the production process, the appropriate control, and to improve the quality of regulation in the paper; on the allocation of appropriate implementation of a reasonable device to meet the needs of production management. This article has made a Circulating Water of drug treatment automatic device, the production in the practical application of the test. By comparing and analyzing the device in DaqingHongwei power plant grand system of circulating water system used before and after the vote shows that, this device is sensitive and reliable, and could be applied broadly.
