Description
【Technical field】
The utility model is related to heat energy technology field, more particularly to a kind of raising efficiency of combustion effectively reduces nitrogen oxides
The multi-functional environment-protection heating unit of discharge.
【Background technology】
Nitrogen oxides (nitrogen oxides) includes multiple compounds, such as nitrous oxide (N2O), nitric oxide
(NO), nitrogen dioxide (NO2), nitrogen trioxide (N2O3), dinitrogen tetroxide (N2O4) and dinitrogen pentoxide (N2O5) etc..Except dioxy
Change beyond nitrogen, other nitrogen oxides are extremely unstable, meet light, wet or thermal change into nitrogen dioxide and nitric oxide, nitric oxide is again
Become nitrogen dioxide.Nitrogen oxides all has different degrees of toxicity.
The NOx of human activity discharge, most of combustion process from fossil fuel, such as automobile, aircraft, internal combustion engine and work
The combustion process of industry kiln；Also from production, using the process of nitric acid, as nitrogen fertilizer plant, organic intermediate factory, coloured and black are golden
Belong to smeltery etc..The NOx that the whole world is discharged to air due to mankind's activity every year is more than 60,000,000 tons.Damages of the NOx to environment
Effect is very big, it is both to form one of main matter of acid rain and form the important substance of photochemical fog in air and disappear
Consume O3An important factor.
Nitrogen oxides can stimulate lung, make one the more difficult respiratory disease for resisting flu etc, and respiratory system is problematic
Personage such as asthmatics, can be easier to be influenced by nitrogen dioxide.For children, nitrogen oxides is likely to result in lung's development
It is impaired.Research points out that sucking nitrogen oxides for a long time may result in lung's structural change, but still not can determine causes this consequence
Amount of nitrogen oxides and sucking gas time.

Reached by the physics such as alkaline matter absorption and sorption, oxidation, neutralization, chemical process and dispel SO2Wait the mesh of acids (HF, HCl)
's.Its Processing tecchnics mode, industry are divided into dry method, wet method, semidry method.Although existing sulfur removal technology has his own strong points, effect is fair.
But no matter any method, have that investment is big, and flue gas flow is in 1.5 ten thousand m3The small-scale abatement equipment investment of/h is not low
In 3,000,000 yuan；The feature that floor space is wide, operating cost is high.The improvement enthusiasm of strong influence enterprise and operation continue
Property.
In addition for existing boiler also there are ignition temperature than relatively low, burning time is short, and fuel is difficult that burning is complete, efficiency of combustion
Low and nitrogen oxides in effluent content is high, and environment is caused seriously to pollute.
