Sulfur dioxide is a gaseous pollutant which has a large influence on atmospheric pollutants and has great harm to human bodies, the environment and ecological systems. With the stricter environmental requirements, the problem of S02 emission is receiving more and more attention. The sulfur dioxide is mainly derived from the combustion process of fossil fuels such as coal, petroleum and the like, and the flue gas emission in the roasting and smelting processes of ores. The smoke discharged by various combustion boilers, particularly boilers in thermal power plants, has the characteristics of low concentration, large smoke quantity, much floating dust and the like, and is difficult to treat. The technology for purifying sulfur dioxide in the discharged flue gas is generally to carry out desulfurization through a spray tower.

At present, a spray tower usually comprises a cylindrical tower body, a slurry pool is arranged at the bottom of the tower body, an air inlet is arranged on the upper portion of the tower body corresponding to the slurry pool, an air outlet is arranged at the top of the tower body, spray pipes are arranged in the middle of the tower body corresponding to the air inlet and the air outlet, spray heads are arranged on the spray pipes, and a guide pipe for connecting the slurry pool and the spray pipes is further arranged on the outer side of the tower body.

When the device is used, polluted flue gas enters the tower body from the air inlet, alkaline solution is filled in the slurry pool, the alkaline solution flows back to the spray pipe through the guide pipe and is sprayed out by the spray head, and the sprayed alkaline solution and sulfur dioxide in the rising polluted flue gas are subjected to neutralization reaction so as to achieve the purpose of purifying and polluting the flue gas.

The existing spray tower mainly has the following problems: 1. the water mist generated in the spraying process is large; 2. the whole structure is made of metal materials, and the volume is heavy; 3. the structural design of the desulfurization tower is defective, so that the desulfurization effect is poor.
