Abstract

The invention relates to a method for optimizing an industrial circulating water system, comprising the following steps: 1, establishing a water consumption optimization model for each equipment circulating water subsystem with a minimum circulating water consumption as a target according to water consumption characteristics of each equipment circulating water subsystem, and determining a water consumption optimization scheme for each equipment circulating water subsystem; 2, establishing a complete process model of the circulating water system based upon the water consumption optimization to each equipment circulating water subsystem and according to pressure characteristics of each equipment circulating water subsystem, calculating pressures of all equipment and pipe networks in the circulating water system and determining a pressure optimization scheme of the circulating water system according to a calculation result; 3, determining an electricity saving optimization scheme of the circulating water system based upon the water consumption optimization and the pressure optimization and according to operating requirements of the circulating water system. The method is more suitable for the practical circulating water system of enterprises, so the water-saving and energy-saving effects are more obvious.

Description

technical field [0001] The invention relates to an industrial public engineering system, in particular to a circulating water system applied in the fields of metallurgy, petroleum, chemical industry and the like. Background technique [0002] The circulating water system is an important public project in the electric power, metallurgy, petrochemical and other industries. The operation quality of the circulating water system directly affects the production capacity of the enterprise, and is related to the operation safety of production devices and equipment, as well as the yield and quality of products. According to industry statistics, the circulating water consumption of the circulating water system accounts for about 80% of the industrial water consumption, and it is the system with the largest water consumption in industrial manufacturing, especially in the petrochemical field. The proportion will also increase. At the same time, during the operation of the circulating ...
