Abstract

The invention discloses a data operation optimization method based on power plant desulfurization system, and the method comprises the steps: obtaining the actual operation data of a power plant actual operation system in a certain time period, and carrying out the preprocessing and regression analysis of the actual operation data; dividing different working conditions according to the operation load, and performing numerical simulation to obtain overall flow field, temperature and SO2 component distribution conditions of the desulfurization system under different working conditions; carrying out big data analysis on the actual operation data of the desulfurization system of the coal-fired power plant to obtain an optimal interval of the operation data under the determined working condition; and practicing the big data optimization result in the simulation result to check the accuracy of the optimization result. According to the method, the working conditions are firstly distinguished before the neural network prediction model is established, so that the data size is reduced, the relationship among the energy consumption, the sulfur removal rate output parameters and the influence factors is relatively clear and simple, and the precision can be ensured.

Description

technical field [0001] The invention relates to the technical field of air pollution control of coal-fired boilers, in particular to a data operation optimization method based on a desulfurization system of a power plant. Background technique [0002] At present, environmental pollution has become one of the main roadblocks hindering the healthy, high-quality and sustainable development of the country's economy, and coal-fired power stations are the key targets of environmental problems, and the country continues to improve pollutant discharge standards. In order to meet pollutant discharge standards, coal-fired power stations often adopt countermeasures of fully using materials for decontamination, which leads to a waste of resources to a certain extent. [0003] At the same time, the desulfurization system involves heat and mass transfer, acid-base neutralization, water evaporation, droplet coalescence and fragmentation, etc., and the actual operation is complicated. Altho...
