Abstract

The invention belongs to the field of flue gas treatment and discloses a preparation used for desulfurization, denitrification and dust removal of flue gas. Activated carbon, sepiolite, calcium fluoride, high-aluminum bauxite and a nano material are used in the preparation. The invention further provides a preparation method of the preparation. The preparation integrates the functions of desulfurization, denitrification and dust removal, the preparation method is simple, and efficiency is high.

Description

technical field [0001] The invention belongs to the field of flue gas treatment, and in particular relates to a preparation for flue gas desulfurization, denitrification and dust removal and a preparation method thereof. Background technique [0002] Smoke is a mixture of gas and smoke, and is one of the main causes of air pollution. The composition of the flue gas is very complex. The gas includes sulfides, carbon compounds, and nitrogen oxides. The smoke includes fuel ash, coal particles, oil droplets, and high-temperature cracking products. Therefore, the pollution of flue gas to the environment is the compound pollution of various poisons. The harmfulness of smoke to the human body is related to the size of the particles. The most harmful to the human body is the floating dust with a diameter of less than 10 microns, especially the 1-2.5 micron floating dust is the most harmful. Air pollution from smoke and dust is closely related to meteorological conditions, and wind...
