Sustainable Mining and Metallurgy

In the process of domestic waste incineration, a large number of off-gas containing pollutants is produced. Aiming at the requirements of ultra-low emission of waste incineration off-gas pollutants in the future, this paper combined the deep desulfurization technology and the deep denitrification technology, introduced process, principles, advantages and disadvantages of the whole process of SCR denitrification combined with wet deacidification and eliminating white mist, the whole process of efficient SNCR denitrification combined with wet deacidification with acoustic temperature measurement system and the whole process of PNCR denitrification combined with wet deacidification. By comparing the above off-gas cleaning process solutions, three recommended technical routes of the whole process were given.
