Description

Technical Field

[0001] The invention relates to the technical field of desulfurization equipment, in particular to a composite desulfurization tower. Background Art

[0002] At present, various industrial boilers or industrial furnaces work by burning fuel. During use, smoke is discharged. However, since the smoke contains a large amount of harmful gases such as sulfur dioxide, it will cause environmental pollution if it is directly discharged into the air. Therefore, desulfurization equipment is generally used to desulfurize the smoke discharged by industrial boilers or industrial furnaces before it is discharged into the air.

[0003] Since the waste gas contains particulate impurities, before passing the waste gas into the desulfurization tower, the waste gas is generally filtered to reduce the particulate impurities in the waste gas. When filtering the waste gas, the impurities in the waste gas are easily deposited on the surface of the filter screen, causing the filter screen to be blocked, affecting the discharge of the waste gas into the desulfurization tower. Therefore, a composite desulfurization tower is proposed. Summary of the invention
