Description
Technical field
The utility model relates to a kind of flue gas processing device, especially dust-removal and desulfurizing denitration oxidation tank.
Background technology
In current fume treatment, desulfurization mainly adopts gypsum desulfurization, operation principle is: added water by agstone and make slurries and pump into absorption tower as absorbent and fully contact mixing with flue gas, sulfur dioxide in flue gas and the calcium carbonate in slurries and the air blasted from tower bottom carry out oxidation reaction and generate calcium sulfate, after calcium sulfate reaches certain saturation degree, crystallization forms dihydrate gypsum.The gypsum slurries of discharging through absorption tower, through concentrated, dehydration, makes its water content be less than 10%, and then deliver to gypsum storehouse with conveyer and stack, the flue gas after desulfurization removes droplet through demister, then after heat exchanger heat temperature raising, enters air by chimney.This sulfur method absorbent utilization rate is very high, and calcium sulfur ratio is lower, and desulfuration efficiency can be greater than 95%.But equipment is huge, floor space is large, and complex process, energy consumption is high.
Denitration adopts selective catalytic reduction.Flue gas enters Benitration reactor, under the effect of catalyst, make NH
3react with NOx.SCR (SCR) technology applies at most at present and the most fruitful gas denitrifying technology.SCR technology is under metallic catalyst effect, using NH3 as reducing agent, NOx is reduced into N
2and H
2o.The O of the remnants in NH3 discord flue gas
2reaction, and if adopt H
2, CO, CH
4deng reducing agent, they are meeting and O while reducing NOx
2effect, therefore claims this method for " selective ".By adopting suitable catalyst, above-mentioned reaction effectively can be carried out in the temperature range of 290 DEG C ~ 410 DEG C, can obtain the NO up to 80% ~ 90%
xremoval efficiency.But the method cost of investment is too high, and catalyst is expensive, catalyst is needed within several years, just change a catalyst by flue gas corrosion, and system is run at high dirt environment in addition, often has the problems such as reactor plugs.
Utility model content
For solving the problem, the utility model provides a kind of energy-efficient, and invest little, take up an area little dust-removal and desulfurizing denitration oxidation tank, concrete technical scheme is:
Dust-removal and desulfurizing denitration oxidation tank, comprises oxidation tank, steel wire, denitration shower nozzle, desulfurization shower nozzle and feet;
Flue gas inlet pipe is arranged at the top of described oxidation tank, has treatment fluid in oxidation tank, has Sewage treatment pipe and blast pipe bottom oxidation tank; One end of described blast pipe is in the inside of oxidation tank and exceed the liquid level for the treatment of fluid; Described tarpaulin is fixed on the top of blast pipe; It is inner and above tarpaulin that described steel wire is arranged on oxidation tank; Described denitration shower nozzle and desulfurization shower nozzle are located at the top of oxidation tank; Described feet is fixed on the bottom of oxidation tank;
Oxidation tank also comprises air intake duct; Described air intake duct is positioned at above steel wire; Described air intake duct is connected with blower fan.
Described denitration shower nozzle and desulfurization shower nozzle are all no less than one.
Described steel wire is no less than two-layer.
Desulfurization sprinkler calcium hydroxide breast, calcium hydroxide breast droplet mixes with flue gas and contacts, and generate calcium sulfite with the sulfur dioxide generation chemical reaction in flue gas, the sulfur dioxide in flue gas is removed.Desulfurization process is comparatively simple, system reliability is high, and desulfurization degree can reach more than 85%.
Denitration sprinkler ammoniacal liquor.First the nitric oxide in flue gas is oxidized to water-soluble nitrogen dioxide by the fresh air blown in oxidation tank, ammoniacal liquor droplet mixes with the flue gas containing nitrogen dioxide, make nitrogen dioxide water-soluble and to react generation nitrate with the ammonia in water, removing the nitrogen oxide in flue gas.Ammoniacal liquor can react with the sulfur dioxide in flue gas simultaneously, and the intermediate material of generation also can denitration, finally generates ammonium sulfate.
The employing of steel wire adds the contact area of flue gas and calcium hydroxide breast and ammoniacal liquor, can play the effect of dedusting simultaneously.
Dedusting, desulphurization and denitration are included in same system and are processed by the dust-removal and desulfurizing denitration oxidation tank that the utility model provides, energy-efficient, and invest little, take up an area little, resistance is little, and operating cost is low, power saving, water-saving, and dedusting, desulphurization and denitration efficiency are high.
