Description

Technical Field

[0001] This utility model relates to the field of environmental protection and pollution control technology, and more specifically to a low-temperature flue gas denitrification tower. Background Technology

[0002] Low-temperature denitrification towers are devices used to remove nitrogen oxides from flue gas. They are mainly used in industrial flue gas treatment and environmental protection. Their working principle is usually to convert nitrogen oxides into harmless nitrogen and water at a low temperature through processes such as selective catalytic reduction or selective non-catalytic reduction. After the flue gas enters the low-temperature denitrification tower, a reducing agent (such as ammonia or urea) is first injected. Under the action of a catalyst, the nitrogen oxides react with the reducing agent to be converted into nitrogen and water vapor. Finally, the qualified flue gas is discharged through the chimney.

[0003] When existing flue gas low-temperature denitrification towers are in operation, the flue gas entering the tower usually contains moisture and dust particles, which can easily affect the working effect of low-temperature denitrification. In addition, flue gas is usually sent into the flue gas low-temperature denitrification tower through pipelines. If the pipelines are damaged due to use over time and need to be replaced, it is quite troublesome. Therefore, this utility model provides a flue gas low-temperature denitrification tower.
