Desulfurization and denitration environment-friendly treatment method

Abstract

The invention relates to a desulfurization and denitration environment-friendly treatment method. Flue gas enters the pipeline I from the gas inlet I; then the flue gas enters the desulfurization solvent in the desulfurization tank body from an exhaust hole formed in the bottom of an exhaust pipe I fixedly mounted on the right side of the pipeline I; the stirring motor drives the stirring shaft, and the stirring shaft drives the stirring blades to stir the desulfurization solvent so that the reaction is accelerated to perform desulfurization, and in the denitration tank body, the reaction is also accelerated to perform denitration, the reaction time of desulfurization and denitration is saved, and the desulfurization and denitration efficiency is improved. On the basis of the prior art, the preparation process of the desulfurization and denitration catalyst is optimized, the atmospheric pressure low-temperature plasma treatment process is added, and the desulfurization and denitrationefficiency of the desulfurization and denitration catalyst is improved to the maximum extent.

Description

technical field [0001] The invention relates to an environmental protection treatment method for desulfurization and denitrification. Background technique [0002] In the working process of thermal power plants, a large amount of coal needs to be burned. Since the coal contains more sulfides and nitrates after mining, the sulfides and nitrates flow with the flue gas during the coal combustion process. The existing The technology often uses chimneys at high positions to discharge the above substances directly into the air, which increases the efficiency of pollutant diffusion to a large extent, and affects the living environment of people around them, making people's living conditions worse. Therefore, there is a need for a device that can desulfurize and denitrify these flue gases to avoid environmental pollution by the flue gases. [0003] The current desulfurization and denitrification environmental protection treatment methods in daily life consume too long time in the p...

[0002] In the working process of thermal power plants, a large amount of coal needs to be burned. Since the coal contains more sulfides and nitrates after mining, the sulfides and nitrates flow with the flue gas during the coal combustion process. The existing The technology often uses chimneys at high positions to discharge the above substances directly into the air, which increases the efficiency of pollutant diffusion to a large extent, and affects the living environment of people around them, making people's living conditions worse. Therefore, there is a need for a device that can desulfurize and denitrify these flue gases to avoid environmental pollution by flue gases

[0003] The current desulfurization and denitrification environmental protection treatment methods in daily life consume too long time in the process of flue gas desulfurization and denitrification, which reduces the efficiency of desulfurization and denitrification. Most of the desulfurization and denitrification together are used to mix the desulfurization and denitrification solutions. After the desulfurization and denitrification is completed, these mixed solutions are difficult to handle
