Problems solved by technology
[0003] During desulfurization, air for oxidation needs to be injected into the desulfurization tower, and the oxidation air is passed into the bottom of the reaction slurry tank of the absorption tower, and then the bubbles rise to the surface of the slurry tank by buoyancy, and are mixed with the slurry during the rising process, and the oxidation reaction is carried out. And form impurity precipitation, however, when injecting air for oxidation reaction, the air rises by its own buoyancy and mixes with the liquid. Mixing with air, the mixing time required for full reaction is longer, which affects the working efficiency of the desulfurization tower

The present invention relates to the technical field of flue gas purification and desulfurization, in particular to a flue gas purification and desulfurization tower, comprising: a tower body, the outside of which is connected with an air intake pipe for air intake of an air intake pump; There is a baffle, and a rotating area is formed between the baffle and the housing; the fan blade is installed in the rotating area of the housing through the rotating shaft, and the rotating area communicates with the intake pump through the intake pipe, so that the airflow in the intake pipe can push the fan blade and the rotating shaft rotates; the rotating plate is installed on the top of the casing, and forms a passage for air flow between the partition and the partition, and the passage and the rotating area communicate with each other through the passage holes provided on the partition. The invention uses the airflow as the driving force to link the rotation of the exhaust pipe so that the slurry is in motion and the air bubbles are in motion at the same time, the slurry and the air bubbles are fully mixed, the time for full reaction is shortened, and the working efficiency of the desulfurization tower is improved.
Description
technical field [0001] The invention relates to the technical field of flue gas purification and desulfurization, in particular to a flue gas purification and desulfurization tower. Background technique [0002] The desulfurization tower is a tower-type equipment for desulfurization treatment of industrial waste gas. The flue gas enters the desulfurization tower from the air inlet at the bottom of the tower, and rotates up due to the guiding effect of the tray blades, and sprays the slurry flowing down one by one on the tray. The fine mist droplets of 10 microns increase the contact area between gas and liquid sharply, and the gas and liquid droplets fully contact, and the SO2 in the gas is easily absorbed by the alkaline liquid to achieve the effect of desulfurization. [0003] During desulfurization, air for oxidation needs to be injected into the desulfurization tower, and the oxidation air is passed into the bottom of the reaction slurry tank of the absorption tower, and...
