Abstract

The invention discloses an automatic circulating water control system and method based on an intelligent instrument. The automatic circulating water control system comprises an online instrument testing device, a data analysis and control system, a sulfuric acid (or hydrochloric acid) dosing system, a scale inhibitor dosing system, a corrosion inhibitor dosing system and the like. An outlet pipeline of the circulating water pump is connected with a sampling pipe, main monitoring indexes such as pH, alkalinity, calcium ions, hardness, chloride ions and sulfate ions of circulating water are monitored through an online instrument testing device, tested data are subjected to data analysis through a data analysis and control system, and the deviation condition of the main indexes and normal control numerical values is judged. Dosing amounts of the sulfuric acid (or hydrochloric acid) dosing system, the scale inhibitor dosing system and the corrosion inhibitor dosing system are adjusted through the data analysis and control system.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and relates to a circulating water automatic control system and method based on an intelligent instrument. Background technique [0002] At present, the circulating water system of thermal power plants mainly prevents scaling and corrosion of the condenser system and piping system through the regulation of water quality. The routine operation is to add acid to the circulating water to adjust the alkalinity and pH value, add scale inhibitors to inhibit scale, and add corrosion inhibitors to prevent system corrosion. Usually adding acid, adding scale inhibitors and corrosion inhibitors are all added quantitatively, the response to the water quality change of circulating water make-up water is slow, and the dosage cannot be adjusted in time, which will lead to scaling and corrosion problems in the system. [0003] The water quality of the existing circulating water is manually tested in the...
