Coal slime fluidized bed boiler desulfurization collaborative optimization operation method

Abstract

The invention relates to the field of SO<2> pollutant treatment of coal-fired power plants. The invention aims to solve the problem of high SO<2> emission after desulfurization in the prior art. The invention discloses a coal slime fluidized bed boiler desulfurization collaborative optimization operation method. A desulfurization collaborative optimization operation system comprises the followingmodules: a DCS data acquisition module, an A/D and D/A conversion module, a central processing system module, a prediction control module, a man-machine interaction module and an optimization calculation module. The invention provides the coal slime fluidized bed boiler desulfurization collaborative optimization operation method. According to the method, modeling and optimization calculation are carried out on the process of the whole desulfurization system, and the SO<2> concentration value after optimization calculation is subjected to predictive control, so that the operation cost of the whole desulfurization system is minimized, and the result after optimization solution is subjected to predictive control to obtain the lowest operation cost, thereby realizing the economic and stable operation of SO<2> removal and improving the economic benefits of enterprises.

Description

technical field [0001] The present invention relates to coal-fired power plant SO 2 In the field of pollutant treatment, it particularly relates to a desulfurization collaborative optimization operation method of a coal slime fluidized bed boiler. Background technique [0002] my country is one of the countries with the most serious air pollution. According to statistics, in my country's air pollution sources, combustion emissions of SO 2 Accounting for more than 85% of total emissions. SO 2 A large amount is discharged into the air, resulting in frequent acid rain, which has caused immeasurable losses to the social and economic development of our country. In order to control pollution and protect the environment, relevant departments such as the Ministry of Environmental Protection have formulated a series of laws, regulations and standards. In December 2015, the National Development and Reform Commission, the Ministry of Environmental Protection, and the National Ener...
