[0002] The contents of environmental protection projects mainly include air pollution prevention and control projects, water pollution prevention and control projects, solid waste treatment and utilization projects, and noise control projects. Flue gas is a mixture of gas and smoke, which is the main cause of air pollution in residential areas. It mainly comes from the emission of flue gas during industrial production. Sulfur dioxide has a strong pungent odor and will endanger people's lives. Flue gas desulfurization and purification treatment is required when the flue gas is discharged.

[0003] The purification device in the prior art sprays alkaline liquid through a nozzle to mix with the flue gas to achieve desulfurization and purification of the flue gas. The alkaline liquid can better react with the sulfur dioxide in the flue gas in the spraying state. The liquid spraying flow speed is fast, and too much alkaline liquid is required for continuous spraying. If the outflowing liquid cannot be well collected for secondary spraying, it will cause waste of alkaline liquid and increase the desulfurization cost. The method of collecting it through a separate structure for reuse will easily affect the use effect of the alkaline liquid and is not conducive to use.
