Description

technical field [0001] The invention belongs to the technical field of air pollution control, and in particular relates to an integrated device for desulfurization and denitrification of waste gas from tar processing. Background technique [0002] Petrochemical enterprises will produce a large amount of waste gas in the process of tar processing and production. This waste gas will contain complex pollutants such as large molecular weight organic matter (heavy tar), fine particles, NOX and SO2, among which 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 endanger the environment, but also have a great impact on human daily life. [0003] The Chinese invention patent with the publication number CN104606994B discloses an integrated device for dust removal, denitrification and desulfurization. From the bottom of the device upwards, there are electric dust removal area,...

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
