Efficient full-automatic tracing dosing process

Abstract

The invention belongs to the field of circulating cooling water treatment, particularly relates to a high-efficiency full-automatic tracing dosing process, and provides the following scheme aiming at the problems that the dosing amount is difficult to control and water pollution is easily caused in the prior art. The system comprises a circulating water pump, a cooling tower, a circulating metering pump, a water quality monitoring system, a tracing dosing system, a PLC intelligent control system, an electric blow-down valve, an on-line calcium hardness meter, an on-line total dissolved solid meter, an on-line total alkalinity meter, an on-line thermometer, an on-line pH meter, a corrosion inhibitor metering pump, a scale inhibition dispersant metering pump, an on-line medicament concentration tracing probe and an operation screen. In order to achieve the purpose of operation maintenance and add a corrosion inhibitor and a scale inhibition dispersant more scientifically and economically, the invention develops an efficient tracing dosing system which judges the corrosivity and the scaling property of the water quality of the system according to the real-time RSI stability index of the water quality of the system and then accurately and scientifically adds the corrosion inhibitor and the scale inhibition dispersant respectively according to the range of the RSI stability index.

Description

technical field [0001] The invention relates to the technical field of circulating cooling water treatment, in particular to a high-efficiency full-automatic tracer dosing process. Background technique [0002] The patent with the application number of CN201611126810.7 discloses an integrated intelligent dosing process for scaling and anti-scaling. The circulating cooling water system has problems such as corrosion, scaling and microbial growth during operation. Scale and corrosion inhibitors and fungicides to solve. However, in the actual operation process, there are inaccurate or unreasonable chemical dosing concentrations, too high or too low, which fail to achieve the purpose of operation and maintenance, increase maintenance costs or cause water pollution. [0003] The most common method of dosing and concentration multiplier control in the market is to calculate the daily sewage discharge through parameters such as the real-time circulation volume of the cooling water...
