Thermal power plant water supply and drainage network management method and system based on three-dimensional display

Abstract

The invention relates to a thermal power plant water supply and drainage management method and system based on three-dimensional display, wherein the system comprises a production water tank, a rainwater recycling unit, a domestic water unit, a chemical water treatment unit, an auxiliary machine cooling unit, a main machine cooling unit, a comprehensive utilization unit, a unit, a domestic sewagepool, an industrial wastewater treatment unit, a service water tank, a desulfurization unit and a desulfurization wastewater zero discharge element. The management method comprises the following stepsof (1) establishing a three-dimensional display model of a power plant water supply and drainage network system; (2) acquiring relevant information points, and extracting all relevant data of the instantaneous optimal value; (3) running the three-dimensional display model, and displaying a network three-dimensional diagram and a water balance test block diagram; (4) carrying out online monitoringon the water balance state of the water supply and drainage network system; (5) analyzing over-standard data, performing automatic running and adjusting, and giving out an early warning when the system is abnormal; and (6) solving the problems based on an expert consultation and diagnosis technology. According to the method, visual grading management is carried out on the water resources of the thermal power plant, zero emission of the wastewater is realized, the production cost is lowered, and the natural environment is protected.

Description

Technical field [0001] The invention belongs to the technical field of factory water supply and drainage management, and relates to a method and system for water supply and drainage network management of thermal power plants based on three-dimensional display. Background technique [0002] Water resources are basic natural resources and strategic economic resources, and an important foundation for sustainable social and economic development, maintaining ecological balance and a harmonious environment. Of the total installed power generation capacity in the country, the water consumption of thermal power generation accounts for 40% of the total industrial water consumption. Thermal power plants consume a lot of water, and the water problem has become a restrictive factor in the construction and development of the electric power industry in the north. Therefore, it is necessary to do a good job in efficient management of water resources in thermal power plants and build a water sup...

Problems solved by technology

[0004] Due to the limitations of the program design itself, the traditional DCS system and PLC controller are inconvenient for advanced and complex performance calculation and analysis, and at most realize simple PID deviation adjustment. The traditional DCS system can no longer meet the management needs of today's information technology development.

[0005] At present, thermal power enterprises with good water management can preliminarily realize the hierarchical management of water resources in the whole plant and the automatic generation of reports related to water management, but cannot realize the comprehensive balance and online testing of water quality and water quantity in the water system of the whole plant, and cannot realize the water quality of the whole plant. Balance and unbalance rate online test, not to mention the automatic monitoring and intelligent adjustment of water equipment
