A global optimization method for an ultra-low emission multi-pollutant collaborative removal system

Abstract

The invention relates to a global optimization method for an ultra-low emission multi-pollutant coordinated removal system. Through accurate modeling of the multi-device multi-pollutant coordinated removal process of the ultra-low emission system, the generation, migration, Accurate description of conversion and removal processes; accurate assessment of multi-pollutant abatement costs under different loads, coal quality, pollutant concentrations and operating parameters through cost evaluation methods for global operation in ultra-low emission systems; multi-pollutant and multi-target The global operation optimization method of multiple working conditions realizes minute-level planning and optimization of the emission reduction of the global pollution reduction device under different emission targets; the advanced control method that reliably meets the emission standards of low-emission and multi-pollutants ensures reliable emission reduction and calorific reduction of pollutants. edge control. The invention innovates the modeling, optimization and control methods of the ultra-low emission system from the model, architecture and algorithm levels, improves the controllability and adjustment capability of the system, and guides the efficient, reliable and economical operation of the ultra-low emission system.

Description

technical field [0001] The invention belongs to the technical field of control of energy and environmental engineering pollution reduction devices, and in particular relates to a global optimization method for an ultra-low emission multi-pollutant collaborative removal system. Background technique [0002] my country is rich in coal resources, which can stably meet the demand for electricity for development, which determines the pattern of my country's power generation energy dominated by coal. This energy structure and traditional coal utilization methods produce a large amount of air pollutants. With the continuous development of my country's economy, the requirements for environmental protection are gradually increasing. It is the general trend for coal-fired units to implement clean production. Emissions are a developing trend. [0003] In order to meet environmental protection requirements, coal-fired power plants in my country have installed dust removal devices, and S...
