Abstract
The invention discloses a desulfurization and flue gas removing technology. The technological process comprises the following steps: an air blowing pump is connected with a desulfurization tower via a pipeline, and the desulfurization tower is used for desulfurizing; primary temperature reduction treatment: flue gas enters a heat exchanger for primary temperature reduction; primary dust removing and dehumidifying treatment: flue gas is guided into a dust removing dryer so that smoke and water mist are removed; impurity and harmful gas removing by chemical reaction: flue gas is guided into each reactor via a flue gas pipe, a temperature control device controls the temperature of each reactor, and the reaction time is controlled to be longer than 6 hours; deep temperature reduction treatment: flue gas is converged into a pressurization pump by a gas collecting pipe, and is pressurized on the pressurization pump to enter a deep refrigerator to be cooled; release: the flue gas is guided into a flue gas storage chamber in a chimney, and is exhausted under an appropriate climate condition. The desulfurization and flue gas removing technology provided by the invention has the advantages that the energy consumption is low, the tail gas treatment cost is reduced, and the treatment effect is improved.
