Production method and flue gas dry desulfurizing method.
Background technology
With the fast development of basic industries, China's economy makes great progress；The ring caused by industrial pollution simultaneously
Border pollution is also increasingly severe.Using coal-fired and fuel oil as the oxysulfide SO included in the waste gas that power source dischargesx, nitrogen
Oxide NOx, the pollutant such as dust and heavy metal exacerbate the generation of haze weather.In China's energy system, coal accounts for
The 75% of whole energy system, much larger than oil, natural gas and waterpower.National SO2The 90% of discharge capacity carrys out spontaneous combustion coal.Therefore,
Reduce SO2Discharge capacity turn into the task of top priority.
Current sulfur method is roughly divided into three classes：(1) wet method, washed using liquid-absorbant (such as water or aqueous slkali)
Wash；(2) semidry method, the moisture in lime slurry, while lime and SO are evaporated using obvious heat of smoke2Reaction generation dry powder-shaped sulfurous
Sour calcium, the characteristics of having wet method and dry method concurrently；(3) dry method, with powdery or granular absorbent, adsorbent or catalyst to remove SO2。

Flue gas after sulphur does not cool, it is not necessary to heats, you can meets the requirement of discharge diffusion.In addition, desulfurization by dry method also has nothing
The advantages that fouling, condensation, blocking, reliability height, secondary pollution are lacked.
Existing frequently-used dry-desulphurizer is based on activated carbon or activated coke.It is a kind of cost-effective with active carbon desulfurization
Sulfur method.Simple to operate because active carbon desulfurization temperature is low, caused sulfuric acid is also used as byproduct recycling, because
This is a kind of very promising sulfur method with active carbon desulfurization.Application No. 99104245.X Chinese patent application discloses
A kind of method that desulfurizing agent is prepared by the use of activated carbon or NACF as carrier loaded cupric oxide, but because carbon material is strong
Low, abrasion height is spent, the number of recycling is few, and production cost is high.
For the activated coke of commercial sizeization application at present there is also desulfurization capacity is relatively low, regeneration is frequent, and usage amount is big etc. asks
Topic.Therefore, the dry-desulphurizer of developing low-cost, high activity is highly desirable, to improve desulfurization performance, reduces usage amount, drop
Low investment and operating cost.
