Description

Technical field [0001] The invention belongs to the technical field of air pollution control, and specifically relates to an integrated device for desulfurization and denitration of tar processing waste gas. Background technique [0002] Petrochemical companies will produce a large amount of waste gas during the tar processing and production process. This waste gas will contain large molecular weight organics (heavy tar), fine particles, NOX and SO2 and other complex pollutants. Among them, SO2 and NOx are the main air pollutants. , Is the main cause of acid rain. If it is not treated and discharged directly, it will not only cause air pollution and harm the environment, but also have a great impact on human daily life. [0003] The Chinese invention patent with publication number CN104606994B discloses an integrated device for dust removal, denitration and desulfurization. From the bottom of the device upwards, there are electric dust removal zone, denitrification zone, desulfuriz...

Problems solved by technology

However, the electrostatic precipitator of this device is not only high in equipment cost and energy consumption, but also difficult to clean and low in safety. Its denitrification uses the traditional spraying denitrification liquid to contact the rising exhaust gas to achieve the purpose of denitrification, resulting in a low contact rate between the denitrification liquid and exhaust gas. Unable to remove the residual dust in the exhaust gas that has not been removed, resulting in unsatisfactory effects of dust removal, denitrification and subsequent desulfurization
