During the smelting process, high temperature steam is discharged with the flue gas, which contains large amounts of nitrogen oxides. If not treated, these nitrogen oxides can cause serious pollution to the environment.
The principle of denitrification process is to convert NOx into non-toxic and harmless nitrogen by adding denitrification agent. This denitrification agent can be reduced, such as ammonia, urea, ethanol and some organic substances. By using this technology, the emission of nitrogen oxides can be effectively reduced and the environment can be protected.
In order to achieve more efficient flue gas treatment, an integrated technical solution can also be adopted, that is, the integrated technology of desulfurization and denitrification. This technology performs both desulfurization and denitrification in one treatment process, and can remove SO2 and NOx from the flue gas at the same time. This can not only improve the processing efficiency, but also save costs. Therefore, denitrification of copper smelting furnace is not only of great significance to environmental protection, but also contributes to the sustainable development of enterprises.
Denitrification technology can effectively reduce nitrogen oxide (NOx) emissions. In copper smelting, high-temperature steam is discharged along with the flue gas, which contains a large amount of nitrogen oxides. If not treated, these nitrogen oxides can cause serious pollution to the environment.
Secondly, the efficient denitrification process can improve the efficiency of copper smelting. For example, the bottom-blown copper smelting technology can, with the joint efforts of managers and technicians, comprehensively exceed the design indicators in a short period of time, so that one furnace plays the role of two furnaces.
In addition, the transformation and construction of the denitrification process of the melting furnace is also the need of energy saving and emission reduction. SCR, SNCR and PNCR are the most popular denitrification processes in melting furnaces. Among them, SCR has high denitrification efficiency but high investment and operating cost, while SNCR has low denitrification efficiency but low investment and operating cost. Therefore, choosing the appropriate denitrification process is of great significance to reduce energy consumption and improve production efficiency.
