This type of equipment plays a vital role in industrial production, aiming to reduce air pollution and protect the ecological environment and human health.

[0003] However, in existing technologies, desulfurizing agents are typically poured into the exhaust gas treatment device, and the exhaust gas enters the desulfurization chamber for desulfurization treatment. However, the sulfur dioxide in the exhaust gas is difficult to mix and react well with the desulfurizing agent, which affects the desulfurization effect. Utility Model Content

Therefore, this invention proposes a high-efficiency desulfurization and dust removal device for furnace exhaust gas.
