Six protective seats 2 are arranged around the outer wall of the desulfurization tower 1, distributed sequentially around its perimeter.

A spraying device 6 is installed on one side of the connecting pipe 5, and a nozzle 7 is installed below the spraying device 6. A mounting base 601 is installed at the lower end of the spraying device 6, and the nozzle 7 corresponds to the mounting base 601. The nozzle 7 and mounting base 601 are connected by threads. A support base 8 is installed below the spraying device 6, and a drain outlet 801 is installed inside the support base 8. A drain pipe 11 is installed below the support base 8 for drainage. Four pipes 11 are provided. The drain pipes 11 are connected to the drain outlets 801. A swirling device 9 is provided at the upper end of the support base 8. A swirling plate 10 is installed inside the swirling device 9 and welded to it. The protective seat 2 enhances the protection of the desulfurization tower 1. The support base 3 supports the desulfurization tower 1. The drain seat 302 facilitates wastewater discharge. The spraying device sprays liquid, thus facilitating flue gas desulfurization. The swirling device 9 enables… When the flue gas passes through the swirl plate 10, it generates a strong centrifugal rotation motion, which fully contacts the liquid in the tower, thereby improving the gas-liquid two-phase mass transfer efficiency and thus improving the desulfurization effect of the flue gas. The drain port 801 and drain pipe 11 allow the liquid to flow easily, and the liquid passing through the drain pipe 11 can react with the lower layer of flue gas to achieve desulfurization. It should be noted that, in order to save space and highlight the innovative elements of this patent, such as the working principle and process of how the liquid reacts with the flue gas, this patent will not elaborate on them.

The drainage seat 302 can facilitate the discharge of desulfurized wastewater, thereby facilitating wastewater treatment.

Liquid is introduced through the water inlet seat 4 and then enters the interior of the connecting pipe 5. It is then sprayed out through the nozzle 7, allowing the liquid to react with the waste gas, thereby desulfurizing the waste gas. The wastewater after the reaction is discharged through the drain seat 302 to avoid pollution to the surrounding environment. The installed swirl device 9 causes the flue gas to generate a strong centrifugal rotation when passing through the swirl plate 10, which fully contacts the liquid in the tower, thereby improving the gas-liquid two-phase mass transfer efficiency and thus improving the desulfurization effect of the flue gas. The set drain port 801 and drain pipe 11 allow the liquid to flow easily, and the liquid passing through the drain pipe 11 can react with the waste gas in the lower layer, thereby facilitating desulfurization and effectively improving the desulfurization efficiency.
