[ background of the invention ]
At present, the wet flue gas desulfurization process is mainly adopted in the industries of thermoelectricity, steel, metallurgy, cement and the like in China to remove sulfur dioxide in flue gas. The desulfurization tower is the most critical core equipment in a wet flue gas desulfurization process system, and can be divided into a spray tower, a bubble tower, a liquid column tower and the like according to different technical characteristics, wherein the spray tower is a mainstream tower type of the wet flue gas desulfurization process and is generally arranged in a mode of countercurrent contact of flue gas and slurry. After the spray layer nozzles close to the tower wall spray the absorption liquid to the inner wall of the desulfurization spray tower, the absorption liquid flows downwards along the tower wall. When the absorption liquid flows to the smoke inlet, the absorption liquid flows down in a waterfall shape.
The waterfall-shaped absorption liquid can block the flue gas entering the spray tower, so that the flue gas resistance is increased, and the energy consumption of the desulfurization fan is increased. The accumulation of solid matters in the flue at the inlet of the absorption tower is easy to cause, the flue and the tower body are corroded, and the operation energy consumption and the maintenance cost are increased. The slurry sprayed to the tower wall of the spray tower does not fully contact and react with the flue gas and flows downwards along the tower wall of the spray tower, so that the desulfurization and dust removal efficiency is reduced.
