Problems solved by technology

However, with the prolongation of operation time and the decline of equipment performance, the desulfurization efficiency will inevitably decrease. At the same time, due to the gradual increase of sulfur content in coal combustion, many wet desulfurization devices have been unable to meet environmental protection requirements.
[0003] Although the technical transformation of the original desulfurization device can improve the performance of the device, its cost often reaches more than 50% of the original device cost

Abstract

The invention relates to the field of chemistry and discloses a devulcanizing additive as well as a preparation method thereof. The devulcanizing additive is prepared from the following components in parts by weight: 30-40% of adipic acid, 15-25% of sodium benzoate, 15-25% of sodium glycollate, 15-25% of sodium acetate and 10-15% of sodium chloride. Under the premise that the existing device is not randomly changed, the desulphurization efficiency can be greatly improved, the energy consumption can be reduced to a certain degree, and the quality of gypsum as a byproduct is improved, so that a new choice is provided for a power plant.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a flue gas desulfurization additive. Background technique [0002] Limestone wet desulfurization technology is currently the most widely used desulfurization process in China, with the highest desulfurization efficiency and the most stable operation, accounting for more than 90% of the desulfurization devices currently built in China. However, with the extension of operation time and the decline of equipment performance, the desulfurization efficiency will inevitably decrease. At the same time, due to the gradual increase of sulfur content in coal combustion, many wet desulfurization devices have been unable to meet environmental protection requirements. [0003] Although the technical transformation of the original desulfurization device can improve the performance of the device, its cost often reaches more than 50% of the original device cost. Therefore, how to improve the des...
