Description
Technical field
The utility model relates to a kind of equipment of producing the sulphur ammonium, is specifically related to the oxidizing and crystallizing section of equipment.
Background technology
With coal or oil is that a large amount of flue gases are discharged in the boiler or the fuel-burning power plant of fuel.These flue gases contain objectionable impuritiess such as SOx, NOx, HCl and HF, and wherein SOx is the essential substance 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 firing 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 quantity dischargeds.Because SO
2Be sour gas, the employing alkaline aqueous solution takes off the SOx in the smoking gas, i.e. flue gas desulfurization (FGD) is effective means, is with a wide range of applications.
Synthetic ammonia is alkaline matter, as sweetening agent, can produce the ammonium sulfate fertilizer of high fertilizer efficiency.This method is called ammonia-process desulfurization technique.
China is a population, grain and chemical fertilizer big country, and the output of chemical fertilizer is converted into synthetic ammonia, is equivalent to 3,500 ten thousand tons/year.Can solve 2,000 ten thousand tons of SO with the FGD technology
2/ year calculating need provide 1,000 ten thousand tons/year of synthetic ammonia, accounts for national synthetic ammonia aggregate demand less than 30%, can produce 4,000 ten thousand tons of ammonium sulfate, nearly 30,000,000,000 yuan of the output value simultaneously.In addition, carbon ammonium or urea only contain nitrogen nutrition, and nitrogenous and sulphur nutrition simultaneously in the sulphur ammonium.Therefore, the sulphur ammonium is than carbon ammonium and the better chemical fertilizer of urea, has huge market outlook in China.But, China, so in the world wide, the output of ammonium sulfate is all very low, all is byproduct basically, does not almost have the factory that produces ammonium sulfate fertilizer specially.Therefore, development is based on the thiamine fertilizer industry of flue gas desulfurization, for promoting that China's Agricultural Development is significant.
Three steps of ammonia-process desulfurization technique correspondence are as follows:
(1) SO
2Absorb, show as the acid-base reaction in the aqueous solution, at first generate ammonium sulphite, react as follows:
SO
2+ H
2O+2NH
3=(NH
4)
2SO
3(ammonium sulphite)
(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 solubleness, 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 ammonia is soluble in water, its first step is easy to realize that assimilated efficiency is very high, can reach more than 99%.But because the more distinctive character of ammonium salt system, the sulfite oxidation in second step is an ammonium sulfate, showed a lot of singularity with the ammonium sulfate crystallization in the 3rd step, caused present industrialization technology very complicated, equipment is huge, the energy consumption height, very uneconomical, be difficult to effectively be promoted.
Sulfite oxidation is compared obvious difference with other sulphite, be, continuous accumulation along with ammonium sulfate concentrations in the solution, ammonium sulfate produces powerful damping action to the oxidation of ammonium sulphite, promptly along with the increase of sulphur ammonium concentration, the oxidation rate of ammonium sulphite sharply reduces, and prior art can significantly hinder O from ammonium sulfate
2This angle of dissolving in the aqueous solution has been set forth this peculiar property.When salt concn during less than 0.5mol/L (about 5% (wt)), the ammonium sulfurous rate of oxidation increases with its concentration, and when surpassing this ultimate value, rate of oxidation increases with concentration and reduces.
Though the oxidation of ammonium sulphite outwardly with SO
2Absorption it doesn't matter, still,, will suppress SO conversely if sulfite oxidation is insufficient
2Absorption.Therefore, with other sulfur methods, such as the calcium method that with the Wingdale is raw material different with the magnesium method that with magnesium oxide is raw material be the oxidising process of ammonia process and SO
2Absorption process is of equal importance.In calcium method and magnesium method, SO
2Assimilated efficiency almost irrelevant with the oxidising process of sulphite (calcium sulfite and magnesium sulfite).Why will emphasize oxidation in these two kinds of methods, especially limestone-gypsum methods, be because will prevent the thionizer fouling stops up, and after wishing to be translated into gypsum, desulfuration byproduct can obtain utilizing.This yet early stage just calcium method does not have the reason of oxidized portion.
For this reason, both at home and abroad industry member developed a kind of multi-functional be the flue gas desulfurization (FGD) unit of raw material with ammonia, ammonium sulfurous oxidation and sulphur crystalline ammonium are separately carried out, guaranteed that the ammonium sulfate concentrations of oxidation panel (in the bottom, absorption tower) is controlled at lower level, improve oxidation rate.Between oxidation panel (being positioned at the bottom) and absorber portion, be provided with enriching section dexterously.Although this technology has been utilized the characteristics of sulfite oxidation preferably, thionizer is slightly existing complicated, and cost is higher, and in addition, flow process is also longer.
Its major cause is, the realization of prior art is based on the intrinsic reaction kinetics of sulfite oxidation process.Obviously, the oxidation effectiveness of sulphite be improved, the rate of mass transfer of oxygen must be strengthened and improve.
