Problems solved by technology
[0003] When the old brine (natural brine) used in the salt industry is extracted from the ground, in addition to sodium chloride, sodium sulfate and other sodium salts used for salt production, it also contains impurities such as calcium sulfate and magnesium sulfate. If these impurities are not removed , it will be brought into the product during production, which will affect the product quality, so it must be treated; in addition, calcium sulfate and magnesium sulfate will scale in the evaporation tank, reduce production capacity, and even make production impossible, so they must be processed. Refined old brine

The invention discloses a desulphurization technology for utilizing a sodium salt in salt making old bittern as a desulfurizer, wherein the desulfurizer in a flue gas desulphurization process uses sodium sulfate / sodium bisulfate in the bittern as a raw material, simultaneously magnesium ion / calcium ion in the old bittern is deposed and separated, and unit nitre output is raised. The technology has advantages of simple operation, high desulphurization efficiency, and high recovery rate of the sodium sulfate product, and can complete a refining process of the old bittern in a whole desulphurization process.
Description
technical field [0001] The invention belongs to the field of wet desulfurization technology, and specifically refers to a desulfurization technology using sodium salt in salt-making old brine as a desulfurization agent. Background technique [0002] my country is a country with a coal-based energy structure, and its coal output ranks first in the world. Coal accounts for 75% of total primary energy consumption. At present, the flue gas of coal-fired boilers is one of the most important sources of air pollution and has become the primary goal of environmental governance. In 2005, my country's sulfur dioxide emissions reached 25.5 million tons, and the total emissions have surpassed that of Europe and the United States, ranking first in the world. Excessive flue gas emissions make the originally valuable sulfur resource a huge pollution source that endangers the environment. [0003] When the old brine (natural brine) used in the salt industry is extracted from the ground, ...
