Embodiment Construction

[0025] The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] Such as figure 1 As shown, the flue gas desulfurization system in the coal-fired power plant involved in the present invention mainly includes a flue gas heat exchange system, a sulfur dioxide absorption system, a slurry preparation system and a gypsum dehydration system. The flue gas heat exchange system realizes the cooling treatment of the raw flue gas 6 and the heating treatment of the clean flue gas 2 through the heat exchanger 3. The cooled raw flue gas 6 is pressurized by the booster fan 7 and then enters the sulfur dioxide absorption system. The flue gas 2 is discharged into the atmosphere through the chimney 1. The role of the absorbent preparation system is to generate and store the absorbent 8, which is produced by mixing and stirring the industrial water 14 and the limestone mixture 15. The sulfur dioxide absorption syste...

Abstract

The present invention discloses an analytical method of desulfurization efficiency influence factors in a flue gas desulphurization system. The analytical method is based on an analytical method of a response surface, only by several groups of experiment data. Single factor analysis and multifactor interaction analysis can be performed, thereby shortening the analytical time, increasing the analytical efficiency, and providing a fine-quality combination of desulfurization efficiency influence factors under a condition of achieving an emission standard reasonably and effectively. The analytical method is convenient and rapid. The analytical method provided by the present invention is applicable to a series of problems of desulfurization efficiency influence factors analysis in a flue gas desulphurization system, has a very good practice guide value and significance on regulating desulfurization efficiency for an actual desulfurization system.

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...
