Under the conditions of carry out, or the NOx in flue gas is optionally reduced into nitrogen under 1000 DEG C of temperature conditionss without using catalyst.
Selective catalytic reduction is due to needing to use the catalyst containing transition metal, and catalyst can be ground by dust in flue gas
Damage and need often to change, while there is the problems such as NH_3 leakage and temperature conditionss are harsh, it is using being subject to certain restrictions, selectivity
Non-catalytic reduction rule denitration effect can not meet strict NOx emission standard, thus its use it is also restrained.And oxidizing process
Then use ozone and H2O2The NO (account for NOx in flue gas more than 90%) in NOx is oxidized to what is easily eluted Deng oxidant
NO2Or N2O5(NO2Account for more than 90%), and with the SO in flue gas2Removed together in wet scrubber tower.Oxidizing process denitration is due to work
Skill is simple, and without using catalyst, Applicable temperature scope is wide, therefore has some superiority in use cost and applicability.Existing
Some SO2In NOx abjection devices, the device that desulfurization and denitration can be carried out simultaneously is seldom, even there is this function
Device, its eliminating efficiency is also very low, as environmental problem is increasingly serious, and more efficient desulfurization and the device of denitration are current rings
The primary study direction that border is administered.
