Description
Technical field
The utility model relates to sintering device flue gas processing equipments, are a kind of comprehensive denitrification apparatus of sintering device flue gas.
Background technique
Currently, sintering machine denitration mostly uses SCR denitration, and although this method denitration effect is pretty good, SCR denitration
It is required that flue gas is at 300 DEG C or more, sintered compound flue-gas temperature is low, about only 120-150 DEG C or so, so some is added using coal gas
The mode of heating of exchanging heat again after heat heats up.Equipment needed for this heating means is all very huge, and investment is big, takes up a large area, and transports
Row maintenance cost is high.Chinese patent ZL201720170462.7 in 2017 discloses a kind of " sintering machine SCR denitration system ", takes
High temperature section flue gas carries out SCR denitration, although this technique is fine, only high temperature section denitration is selected to be difficult to realize in full flue gas
The minimum discharge of NOx, in addition, there is a valve on its every smoke pipe, flue-gas temperature is high, and valve is easy to damage, and not easy to repair
And replacement.
Summary of the invention
The purpose of the utility model is to provide a kind of comprehensive denitrification apparatus of sintering device flue gas, are set with solving existing heating means
It is standby all very huge, it takes up a large area, investment is big, and operating cost is high；Sintering machine SCR denitration system, it is difficult to realize NOx in full flue gas
Minimum discharge, have a valve on every smoke pipe, flue-gas temperature is high, and valve is easy to damage, and not easy to repair and replacement
Problem.
Purpose of the utility model is realized as follows: the sintering device flue gas integrates denitrification apparatus, comprising: sintering owner's cigarette
Road, inner flue, side smoke tube, ammonia system processed, SCR reactor, exhaust fan, ozone blowing area, ozone hybrid reaction area, ozone processed are set
Standby, desulfurizing tower and ash-discharging device, its main feature is that: inner flue is equipped in flue collector, inner flue front end is equipped with preceding fixing closing plate,
Rear end is equipped with rear fixing closing plate, between have an inner flue bracket, the side smoke tube point left and right sides, every side has 23, and 1-3 is section of igniting,
4-15 is high temperature section, and 16-23 is cooling section, the flue collector side between side smoke tube 4 to 15, is equipped with 1-5 high-temperature flue mouth,
Blinds baffle plate is equipped on high-temperature flue mouth, high-temperature flue mouth, which collects, is connected to high-temperature flue, and high-temperature flue is supported by bracket,
It is connected with SCR reactor head, SCR reactor bottom tube is connected with flue collector, and flue collector is connected with desulfurizing tower, in flue collector
It is equipped with exhaust fan, ozone blowing area and ozone hybrid reaction area.
Working principle；High-temperature flue gas removes bulky grain dust, is mixed into along high-temperature flue and ammonia through blinds baffle plate
SCR reactor, after denitration with ignite section and cooling section flue gas mixes, enter ozone blowing area and smelly along flue collector through exhaust fan
Oxygen hybrid reaction area, the lower valency NOx in flue gas is oxidized to high-valence state NOx soluble easily in water, into desulfurizing tower and hydroxide
Calcium reacts, and after the NOx in flue gas absorbs removal in desulfurizing tower, is discharged through desulfurizing tower chimney.
The blinds and vertical axis angle of blinds baffle plate are 45 ° -60 °.
The utility model has the advantage that (1) high temperature section flue gas is directly led out compared with prior art, anti-into SCR
Device denitration is answered, heated by gas is not had to, compared with heating means simple process, saves heating equipment, occupied area is small, small investment, energy consumption
It is low, operating cost is low；(2) compared with sintering machine SCR denitration system, eliminate valve, it is easy to damage to solve valve, and it is not easy to repair more
It changes, it is difficult to realize the minimum discharge problem of NOx in full flue gas.
