Denitrification towers usually use chemical methods for denitrification treatment. In the denitrification tower, the exhaust gas contacts the denitrification agent (such as ammonia, urea, etc.). Through a chemical reaction with the denitrification agent, the nitrogen oxides are converted into nitrogen or other harmless substances, thereby removing the nitrogen oxides in the exhaust gas.

The denitrification tower has reasonable design and stable operation, and can maintain good denitrification effect under different working conditions.

Through denitrification tower treatment, the content of nitrogen oxides in the exhaust gas can be reduced, reducing pollution to the atmosphere and environment, and meeting environmental protection requirements. At the same time, the denitrification tower can also recover part of the denitrification agent, realize resource recycling, and save energy and costs.
