[0002] Sulfur and acid in flue gas refer to sulfur compounds and acidic gases produced during the combustion process. These substances are mainly released after the combustion of sulfur-containing fuels. During the combustion process, elemental sulfur combines with oxygen to form sulfur oxides. Sulfur dioxide is the most common sulfur compound. When sulfur dioxide comes into contact with water vapor and oxygen in the air, it will further oxidize to form sulfuric acid.

[0032] Specifically, the liquid required for desulfurization and deacidification is extracted from the water tank 4 by the water pump 5, and is transported to the booster 7 through the water supply pipe 6. The booster 7 receives the liquid from the water pump 5 and increases its pressure to ensure that the liquid can smoothly reach the five-way valve 8 and form fine droplets at the atomizing nozzle 9. These droplets contact the flue gas entering through the smoke inlet 10 in the adsorption tank 11 to carry out desulfurization and deacidification reactions. Since the atomized droplets are very fine, the contact area with the flue gas can be greatly increased, thereby improving the reaction efficiency.

When the water vapor containing sulfur and acid adsorbed enters the filter device, it will first pass through the high-layer filter 207, and then pass through the middle-layer filter 206 and the bottom-layer filter 205 in turn. Each filter layer will adsorb and filter the sulfur and acid in the water vapor according to its own filter material and design, thereby gradually reducing the content of harmful substances in the water vapor. At the same time, each filter layer is independently hung on the hanging platform. When the filter layer is saturated or needs to be replaced, it can be easily disassembled and replaced.

[0039] Working principle: The liquid required for desulfurization and deacidification is extracted from the water tank 4 by the water pump 5, and is transported to the supercharger 7 through the water supply pipe 6. The supercharger 7 receives the liquid from the water pump 5 and increases its pressure to ensure that the liquid can smoothly reach the five-way valve 8 and form fine droplets at the atomizing nozzle 9. These droplets contact the flue gas entering through the smoke inlet 10 in the adsorption tank 11 to carry out desulfurization and deacidification reactions. Since the atomized droplets are very fine, the contact area with the flue gas can be greatly increased to improve the reaction efficiency. The liquid treated by the adsorption tank 11 flows back to the water tank 4 through the return pipe 12 to realize the recycling of the liquid. The treated flue gas is discharged from the device through the smoke outlet 13, realizing efficient desulfurization and deacidification of the flue gas. Treatment has a positive significance for reducing air pollution and protecting the environment, and the core of the filtering device lies in its layered filtering design. The filter shell 201 serves as the outer shell of the entire device, and a multi-layer hanging platform is arranged inside. Each hanging platform is hung with a corresponding filter layer. When the water vapor containing sulfur and acid adsorbed enters the filtering device, it will first pass through the high-level filter 207, and then pass through the middle-level filter 206 and the bottom-level filter 205 in turn. Each filter layer will adsorb and filter the sulfur and acid in the water vapor according to its own filtering material and design, thereby gradually reducing the content of harmful substances in the water vapor. At the same time, each filter layer is independently hung on the hanging platform. When the filter layer is saturated or needs to be replaced, it can be easily disassembled and replaced.
