Description

technical field [0001] The invention relates to an analysis method for factors affecting desulfurization efficiency in a flue gas desulfurization system. Background technique [0002] Sulfur dioxide is one of the main pollutants in the atmosphere and an important symbol to measure whether the atmosphere is polluted. At present, thermal coal-fired power plants occupy the largest proportion in my country's power generation market, and coal-fired power plants will produce a large amount of sulfur dioxide. As an essential part of the power plant, the flue gas desulfurization system plays an important role in removing sulfur dioxide and improving the atmospheric environment. The load fluctuation will greatly affect the original flue gas flow rate, and then affect the content of sulfur dioxide discharged into the atmosphere. In the flue gas desulfurization system, the pH value of the absorbent, liquid-gas ratio, flue gas flow rate, etc. will all affect the progress of the desulf...

AI Technical Summary

Problems solved by technology

[0003] In the field of desulfurization efficiency analysis, because the flue gas desulfurization system is an actual large system, it is difficult to accurately reflect and simulate the flue gas desulfurization system through simulation technology, the establishment and verification of mathematical models is cumbersome and complicated, and the simulation results are often inconsistent with the actual situation There is a certain gap, and the analysis results are difficult to provide a basis for the actual operation

At present, most studies focus on the single-factor experiment method, that is, the analysis of the desulfurization effect in the flue gas desulfurization system under the condition of considering the single-factor change. This method can only analyze the influence of the single-factor desulfurization efficiency, which has certain limitations.
