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

Abstract

The invention relates to a global optimization method of an ultra-low emission multi-pollutant cooperative removal system, which obtains an accurate description of a multi-pollutant generation, migration, conversion and removal process in a multi-device through an accurate modeling of a multi-device multi-pollutant cooperative removal process in an ultra-low emission system. The multi-pollutant emission reduction cost under different load, coal quality, pollutant concentration and operation parameters is evaluated accurately by the global operation cost evaluation method in ultra-low emissionsystem. Minute-level planning and optimization of emission reduction of global pollution reduction devices under different emission targets are realized by global operation optimization method of multi-pollutant multi-objective and multi-operating conditions. Reliable emission reduction and side-by-side control of pollutants are ensured through advanced control methods with low emission and multi-pollutant emission meeting the standards reliably. The invention innovates the modeling, optimization and control method of the ultra-low emission system from the aspects of model, architecture and algorithm, improves the controllability and adjustability of the system, and guides the efficient, reliable and economic 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...
