Description

Technical Field

[0001] The invention relates to a spray tower system, in particular to a spray tower system with increased reaction area and a waste gas treatment method. Background Art

[0002] A spray tower is a device used to treat waste gas. It allows the waste gas to fully contact with a liquid, and utilizes the solubility of waste gas components in water or chemical reactions to reduce the concentration of harmful substances in the waste gas, thereby ensuring that the discharged gas meets national environmental protection standards. The filler in the spray tower increases the surface area in contact with the gas in the tower, promotes mass transfer, and thus improves the elution effect of harmful components in the gas. Since the filler is fixed, the airflow path tends to be stable, resulting in full contact between the bottom and outer surface of the filler and the gas. However, due to the poor fluidity of the gas inside, the filler's effect is uneven, and the filler's surface is easily clogged due to long-term reaction with the viscous waste gas. The contact area between the gas and the filler is small, and the tower height required is higher to achieve the treatment purpose. Therefore, it is necessary to design a spray tower system structure that solves the above problems.
