Description
Technical field
The utility model relates to a kind of equipment that reclaims oxysulfide, relates in particular to the equipment that reclaims oxysulfide from boiler smoke.
Background technology
With coal or oil is that a large amount of flue gases are discharged in the boiler or the thermal power plant of fuel.These flue gases contain harmful substances such as SOx, NOx, HCl and HF, and wherein SOx is the main matter that forms acid rain.With the difference of burning coal, SO
2Content is usually at 300-5000ppmv (1000-15000mg/Nm
3) between.But exhaust gas volumn is very huge, and the opinion with coal-burning boiler, steam scale are from 35T/h to 2500T/h, and generating set capacity 6MW is to 1000MW, and exhaust gas volumn is by 50,000 Nm
3/ h to 250 ten thousand Nm
3, SO
21000 tons/year to 100,000 tons/year of discharge capacitys.Because SO
2Be sour gas, adopt alkaline aqueous solution except that the SOx in the smoking gas, i.e. flue gas sulphur removal (FGD) is an effective method, is with a wide range of applications.
Synthetic ammonia is alkaline matter, as sulfur elimination, can produce the ammonium sulfate fertilizer of high fertilizer efficiency.This method is called the ammonia process sulfur removal technology.
Three steps of ammonia process sulfur removal technology correspondence are as follows:
(1) SO
2Absorb, show as the acid-base reaction in the aqueous solution, at first generate ammonium sulfite, react as follows:
SO
2+ H
2O+2NH
3=(NH
4)
2SO
3(ammonium sulfite)
(2) sulfite oxidation is an ammonium sulfate, and chemical reaction also takes place in the aqueous solution, reacts as follows:
(NH
4)
2SO
3+ 1/2O
2=(NH
4)
2SO
4(ammonium sulfate)
(3) ammonium sulfate crystallization after the ammonium sulfate concentrations in the aqueous solution surpasses solubility, can crystallization be separated out the solid ammonium sulfate particle.Crystallization also is looked at as a chemical reaction usually, that is:
(NH
4)
2SO
4(L, fluid sulphuric acid ammonium)=(NH
4)
2SO
4(S, solid ammonium sulfate).
Because the recovery of oxysulfide, be to finish with contacting of upstream flue gas by the absorption liquid under the spray, therefore, the distribution situation of absorption liquid, to directly influence absorption efficiency, present recovery oxysulfide equipment, or do not have the absorption liquid distributor, or simply being provided with ingress pipe, its distribution efficiency is very low.Therefore, designing a kind of absorption liquid distributor of optimization, is a crucial key that improves the efficient that reclaims oxysulfide equipment.
