在脱硫领域，脱硫塔又叫吸收塔，顾名思义就是污染物被吸收的塔器。广义上讲，在其内部发生SO2吸收等反应的塔，都可以叫脱硫塔。狭义上，脱硫塔是指湿法脱硫的核心装置。

In the field of desulfurization, desulfurization tower is called absorption tower, just as its name implies, the absorber is absorbed by the tower. In a broad sense, the tower in which the absorption of SO2 and other reactions can be called desulfurization tower. In the narrow sense, the desulfurization tower is the core device of wet desulfurization.

对于它的应用领域，可以认为所有能产生SO2尾气的生产线都可应用。比如火电厂，钢铁厂、烧重油的玻璃厂等等，这些在生产中因燃烧产生大量SO2的领域。

For its application field, it can be considered that all production lines that can produce SO2 exhaust gas can be applied. Such as thermal power plants, steel plants, heavy oil burning glass factories, and so on, these production in the production of large amounts of SO2 field.
