AI Technical Summary
The flue gas moves quickly inside the reaction tower, resulting in a short reaction time and limited contact area with the limestone spray liquid, which makes it impossible to effectively treat sulfur dioxide.
The reaction chamber employs a W-shaped baffle and sponge strip structure to increase the reaction time and contact area between flue gas and limestone spray liquid through multiple sprays and contacts, and the spraying effect is enhanced by atomizing nozzles.
This ensures that sulfur dioxide in the flue gas is fully treated, achieving a highly efficient desulfurization effect and improving the cleanliness of the flue gas treatment.

Abstract
Description

[0002] A large amount of sulfur dioxide or other dust particles and other harmful substances are generated in the process of aluminum electrolysis, which are mostly discharged in the form of flue gas, and these wastes are not treated, which will cause serious damage to the environment. In industry, sulfur dioxide flue gas generated by aluminum electrolysis is basically treated by wet desulfurization. The flue gas is heated and then introduced into the reaction tower. Before this, the limestone liquid at the bottom of the reaction tower is pumped upward to the top of the flue gas pipeline by a hydraulic pump and is sprayed downward by spraying. The flue gas entering the reaction tower through the flue gas pipeline first contacts the limestone spray liquid, and the sulfur dioxide in the flue gas reacts with the limestone liquid, thereby separating from the flue gas, and the remaining flue gas is discharged upward.
[0003] The above-mentioned desulfurization and dust removal method has the following technical problems: the moving speed of flue gas inside the reaction tower is fast, which leads to a short reaction time of flue gas with limestone spray liquid, and the contact area of flue gas with limestone spray liquid is limited, which leads to incomplete treatment of sulfur dioxide in flue gas.
