With the rapid development of industrialization today, air pollution is becoming increasingly serious, among which nitrogen oxides (NOx) emitted by industrial sources is one of the main pollutants. In order to effectively reduce NOx emissions, many industrial enterprises have adopted denitrification technologies such as selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR), but in the operation process, ammonia escape may occur, which will not only cause resource waste, but also may produce secondary pollution. Therefore, it is particularly important to strengthen the prevention and control of denitrification and ammonia escape from flue gas of industrial source.
In order to strengthen the prevention and control of denitrification and ammonia escape of flue gas from industrial sources, the following points need to be done:
1. Ensure that the actual working conditions of industrial enterprises match the design of the denitration system. Including the selection of catalyst, ammonia injection system configuration, reactor design and so on. These can improve the denitration efficiency and reduce ammonia escape.
2. Establish a regular monitoring mechanism to test the performance of the denitration system, find problems in time and carry out maintenance to effectively ensure the stable operation of the system.
3, through the installation of advanced control systems and sensors, to achieve accurate control of the amount of ammonia spray, to avoid excessive ammonia spray resulting in ammonia escape problems, but also to optimize its location and quantity, to ensure the uniform distribution of ammonia in the flue gas.
4. Enhance the skills of the operators, improve their understanding of the operating principle and operating points of the denitration system, minimize the ammonia escape caused by improper operation, and improve their ability to adjust the operating parameters in the actual situation.
5. Encourage research and development of new technologies, promote cooperation between scientific research institutions and enterprises, and reduce the risk of ammonia escape with efficient and environmentally friendly denitrification technologies and materials.
6, by strengthening the formulation of regulations and standards, strictly control emission standards and regulatory measures, punish enterprises with excessive emissions, and take effective measures to reduce ammonia escape.
Strengthening the prevention and control of flue gas denitrification and ammonia escape from industrial sources can not only improve the effective utilization of resources and reduce the operating costs of enterprises, but also help to improve air quality and protect the environment. Comprehensive operation technology, optimization technology, monitoring and maintenance, personnel training, policy guidance and other measures to reduce nitrogen oxide emissions through effective measures to achieve environmental and economic development.
