[0002] The tail gas generated during the production of glass causes great pollution to the air and poses a great threat to people's life, health and safety. Therefore, it is particularly important to treat the tail gas.

[0003] According to the publication number CN220310117U, a tail gas desulfurization tower for glass furnaces is disclosed. The tail gas enters the dust removal box and is dusted by a dust removal net, and then evenly discharged into the absorption liquid through a coil pipe and air outlet holes. At the same time, a water pump pumps the absorption liquid in the treatment pool to the liquid distribution pipe, and fine water mist is formed through a spray head to uniformly contact the tail gas discharged from the treatment pool, improving the desulfurization effect. The moisture in the discharged tail gas is separated by a gas-liquid separation device and refluxed into the tower body, including a tower body, a bottom foot and an exhaust pipe. The bottom foot is fixedly arranged at the bottom of the tower body, and the exhaust pipe is arranged at the top of the tower body; it also includes a gas distribution mechanism, a spraying mechanism, a dust removal mechanism and an emission mechanism. A treatment pool is arranged at the lower end inside the tower body, and the treatment pool is filled with an absorption liquid. The gas distribution mechanism is arranged in the treatment pool, the spraying mechanism is arranged in the middle inside the tower body and above the treatment pool, the dust removal mechanism is arranged on the left side of the tower body, and the emission mechanism is arranged at the top of the exhaust pipe.

[0004] However, the above-mentioned tail gas desulfurization tower for glass furnaces has the following defects:

[0005] The treatment effect on harmful gas substances such as tail gas desulfurization is poor, and the lime slurry cannot be evenly and widely sprayed on the harmful gas. Since the lime slurry and other products will deposit at the bottom inside the desulfurization tower, the bottom deposits cannot be well cleaned, resulting in high labor costs and low purification efficiency.
