Based on the digestion and absorption of SCR flue gas denitrification technology, the world's leading large-scale general-purpose computational fluid dynamics CFD software - FLUNT is used to simulate the SCR reactor, connecting flue and internal parts, and obtain the velocity field, temperature field, pressure field and concentration field of the SCR reactor under different connection methods between the flue and the reactor, the number and arrangement of the turning and guiding devices and the flue gas mixing devices, and the number and arrangement of the ammonia injection nozzles. The above arrangement method is optimized to achieve the most uniform flow rate, temperature and concentration of the flue gas and ammonia mixture entering the catalyst bed, thereby reducing the escape of ammonia and improving the denitrification efficiency.

★FAQ

Q. Why do we need to carry out desulfurization and denitrification?
A. Desulfurization and denitrification are carried out to remove sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) in flue gas, prevent the formation of acid rain and photochemical smog, and reduce the harm to the atmospheric environment and human health. This treatment can effectively control air pollution and meet national emission standards. It is an important measure for green production and sustainable development of industrial enterprises.

Q. How to perform routine maintenance on desulfurization equipment?
A. Daily maintenance of desulfurization equipment includes regular inspection of desulfurization towers, circulation pumps, spray systems and other components to ensure normal operation, cleaning nozzles and preventing blockage; monitoring slurry pH value, density and liquid level, and timely replenishment of absorbent; checking valves and pipelines for leaks; regular inspection of desulfurization circulation systems and demisters to ensure efficient and stable operation of the equipment and extend its service life.

Q. How to choose the right denitrification technology?
A. Choosing the right denitrification technology requires comprehensive consideration of factors such as flue gas composition, temperature, boiler type, denitrification efficiency requirements, and investment and operating costs. SCR is suitable for high-efficiency denitrification needs and is suitable for large and medium-sized boilers; SNCR is suitable for medium and low temperature segments, compact structures, and low-cost scenarios. Compare the technical maturity, site conditions, and environmental protection standards to select the best solution.
