In the present invention：
The technological principle of dry desulfurization is in boiler or kiln：Lime stone powder material (mainly CaCO3Powder) and cigarette
SO in gas2And part SO3, the sour gas such as HCl, HF, in CaCO3The surface of particle reacts, and reacts as follows：
CaCO3+2HCl→CaCl2+2H2O
CaCO3+2HF→CaF2+2H2O
CaCO3+SO2→CaSO3+H2O
CaCO3+SO3→CaSO4+H2O
CaCO3+SO2+1/2O2→CaSO4+H2O
CaCO3Powder is sufficiently mixed in boiler or kiln upper furnace with high-temperature flue gas, so that HCl, HF, SO2、SO3Deng
Sour gas can fully be absorbed, and realize desulfurization；
The technological principle of Dry denitration is in boiler or kiln：In 850~1000 DEG C of this narrow temperature ranges of burner hearth
It is interior, under without catalyst action, NH3Or the amino reductive such as urea optionally reduces the NO in flue gasX, NH3Or urea is also
Former NOXKey reaction be：
NH3For reducing agent：4NH3+4NO+O2→4N2+6H2O
Urea method is reducing agent：NO+CO(NH2)2+1/2O2→2N2+CO2+H2O
When temperature is higher than 1100 DEG C, NH3It can then be oxidized to：4NH3+5O2→4NO+6H2O
The raw materials used CaCO of the present invention3Storage can be mixed in desulphurization denitration powder material warehouse with urea powder, then simultaneously
Spray into burner hearth and carry out desulphurization denitration；
The technological principle of wet desulphurization is in absorption tower：In using sodium carbonate or sodium hydroxide solution as the first Alkali absorption flue gas
SO2, sodium sulfite and solution of sodium bisulfite are generated, soda is added into sulfur removing pregnant solution, is allowed to be converted into alkaline sulfurous acid
Sodium absorbing liquid sends absorption tower recycling back to, due to using soda lye as absorbing liquid, in the absence of fouling and slurry blockage problem,
And sodium salt absorption rate is faster than calcium salt speed, required liquid-gas ratio is much lower, can save power consumption.Therefore, it is of the invention
Using sodium hydroxide alkaline process sulfur removal technology, desulfurizing agent is outsourcing alkali piece, and NaOH solution absorbs the SO in flue gas2, generate HSO3 2-、
SO3 2-With SO4 2-, reaction equation is as follows：
First, sweetening process
Startup stage NaOH solution absorbs SO2And regenerated liquid pH value it is higher when (be higher than 8 when), doctor solution absorbs SO2Master
React and be：
Main reaction during doctor solution pH value relatively low (5~8) is：
2nd, oxidizing process (side reaction)
The technological principle of wet denitration is in absorption tower：Using the strong oxidizing property of ozone, by insoluble lower valency nitrogen oxygen
Compound is oxidized to solvable high-valence state nitrogen oxides, and nox adsorption then is reached into the purpose of removing in scrubbing tower；
Inventor is studied NO oxidation mechanism during ozone simultaneous SO_2 and NO removal, to ozone in flue
Dispensing, gas distribution mode, gas phase hybrid mode, temperature control influence, dust influence etc. done comprehensive simulated experiment, summarize cigarette
Construct O3The detailed chemical reaction mechanism between NOX, the mechanism is more complicated., can be according to low temperature bar in actual tests
Ozone and NO key reaction are studied under part, under cryogenic conditions, O3Key reaction between NO is as follows：
NO+O3→NO2+O2
NO2+O3→NO3+O2
NO3+NO2→N2O5
2NO+O2=2NO2
4NO2+O2+2H2O=4HNO3
2NO+O2=2NO2
4NO2+O2+2H2O=4HNO3
2HNO3+ NaOH=Na (NO3)2+2H2O
Compared to other chemical substances such as CO, SOx in gas phase etc., NOx can be soon by ozone oxidation, and this is allowed for
NOx ozone oxidation has very high selectivity.Because the NOx in gas phase is converted to be dissolved in the ionic compound of the aqueous solution,
It is more complete that this allows for oxidation reaction, so that NOx is irreversibly stripped of, without producing secondary pollution.Through peroxidization,
The ozone of addition is consumed by reaction, and excessive ozone can be decomposed in spray column.In addition to NO, some heavy metals, such as
Mercury and other heavy metal contaminants are also aoxidized by ozone simultaneously.The dust or solid particulate matter of flue gas middle and high concentration are not interfered with
To NOx removal efficiency.
Oxidizing and denitrating ozone can be applied to：Using coal, coke, lignite as fuel public work boiler or kiln；With combustion gas,
Coal, heavy oil are the Industrial Boiler or kiln of fuel；Lead, iron ore, zinc/copper, glass, cement processing, the various stoves of production；For
Handle the combustion furnace of biological waste, tire and other industrial wastes；Come from the acid gas stream of pickling and chemical process；Catalysis is split
Change treating tail gas；The industry such as various municipal administrations and industrial refuse incinerator smoke treating.
The present invention completes the purpose of further desulphurization denitration simultaneously in a unified tower, so as to reach minimum discharge mark
It is accurate.The application of the present invention, will replace original traditional SCR technology, greatlys save investment and operating cost, be boiler or kiln kiln
Stove realizes that minimum discharge target lays the foundation.
It should be understood that example as described herein and embodiment are not intended to limit the invention, this area only for explanation
Technical staff can make various modifications or change according to it, within the spirit and principles of the invention, any modification for being made,
Equivalent substitution, improvement etc., should be included in the scope of the protection.
