The invention relates to a desulfurization dust-removal pipeline with a mixing shower nozzle. The desulfurization dust-removal pipeline comprises a conveying pipeline used for conveying smoke, a mixing shower nozzle, a medicine liquid pool, a medicine conveying pipeline and a blow-off pipeline, wherein the mixing shower nozzle is arranged in the conveying pipeline for spraying mixed bubbles; the medicine storage pool is arranged out of the conveying pipeline for storing medicine liquid; the medicine conveying pipeline is arranged between the medicine liquid pool and the mixing shower nozzle for conveying medicine liquid in the medicine liquid pool to the mixing shower nozzle; the blow-off pipeline is arranged on the bottom of the conveying pipeline for discharging sewage. According to thedesulfurization dust-removal pipeline, the mixing shower nozzle is arranged in the pipeline, so that the medicine liquid in the shower nozzle and smoke in the pipeline are in contact to be mixed so asto be conveyed in a form of mixed bubbles, the contact area of the medicine liquid and the smoke is increased, the smoke and the mixed bubbles are in full contact so as to improve the reaction speedof the medicine liquid and sulphur in the smoke and dust absorption speed, and the desulfurization dust-removal efficiency of the pipeline for the smoke is improved.
Description
technical field [0001] The invention relates to the technical field of gas desulfurization and denitrification, in particular to a desulfurization and dust removal pipeline provided with a mixing nozzle. Background technique [0002] Industrial waste gas contains a large amount of sulfur dioxide and nitrogen oxides. Desulfurization is to remove sulfur dioxide in the flue gas, and denitrification is mainly to remove nitrogen oxides in the flue gas. These two substances will form acid rain when they enter the atmosphere. The harm of acid rain to human beings Very large, coal-fueled flue gas contains these substances, especially in thermal power plants. Now when building power plants, desulfurization and denitrification equipment must be built at the same time. Most of the desulfurization equipment using wet smoke method only makes industrial flue gas and water fully in the desulfurization tower. Exclude after mixing, let the lime or limestone emulsion absorb sulfur dioxide in ...
