Abstract
The invention discloses a technological process for producing acid with sulfur-containing gases, wherein the sulfur-containing gases contain coke oven gas with hydrogen sulfide and industrial waste gas with hydrogen sulfide. The technological process comprises the following steps: directly injecting the sulfur-containing foam prepared through the desulfurization treatment of the sulfur-containing gases, in an incinerator to incinerate, purifying the prepared sulphur dioxide gas, and catalyzing sulphur dioxide gas to absorb and prepare sulfuric acid. The technological process of the invention is simple, is convenient to operate and has good treatment effect and small investment and occupied land; the technological process of refining and decomposing sulfide wastes in the prior art can be simplified; and the pollutions of sulfides to the air and the production environment can be reduced, or the pollutions and damages to the soil caused by burying sulfide wastes can be eliminated fundamentally. Therefore, the industrial waste can be fully utilized, waste can be changed into valuable, the cost can be reduced, the environmental pollution is easy to eliminate, the economic benefit can be increased, a large amount of environmental protection investment and operation cost can be saved and benifits can be brought for social development and human existence.
Description
Technical field
The present invention relates to desulfurization processing and acid-making process method, especially relate to a kind of sulfurous gas processing and both can prevent the pollution of the environment, can produce the processing method of acid again.
Background technology
All can produce a large amount of sulfurous gass in industries such as chemical industry, metallurgy, coking, power plant and aluminium manufacturers: as contain H
2The coke-oven gas of S and contain H
2S, SO
2Industrial gaseous waste.For sulfurous gas,, adopt wet desulphurization (as the desulfurization of HPF method etc.), to reach the effect that purifies coal gas mostly coke-oven gas is removed S-contained substance as coke-oven gas.HPF method sulfur method is: first usefulness doctor solution absorbs the hydrogen sulfide in the coke-oven gas in regenerator column, make hydrogen sulfide form the sulfur-bearing foam, in sulfur melting kettle, separate doctor solution again, drain and make the sulfur-bearing foam become sulphur mud or sulphur cream waste material, because the waste material amount of these sulfur-bearings is big, pile up like a mountain, be difficult to handle, caused environmental pollution for the second time, also contain hydrogenation cyanogen violent in toxicity in sulphur mud or the sulphur cream simultaneously, easily human body is damaged health risk.Sulphur is buried or refined to prior art to sulphur mud or most employing of sulphur cream waste material, handles sulphur mud or sulphur cream waste material but adopt to bury, and not only floor space is big, and can cause serious environmental to pollute, and change and destruction soil form public hazards, cause permanent environmental pollution; Employing is refined into sulphur complex process and contaminate environment once more with sulfide; At present, good multiple enterprises adopts vacuum salt of wormwood method and supporting Top rope method or absorption process (double conversion double absorption, one changes one inhales) handle hydrogen sulfide and prussic acid gas in the coke-oven gas, treatment effect is relatively good, and wherein Top's rope method more can reach environmental protection standard, but there are complex treatment process in absorption process and Top's rope method, construction investment is big, running cost height, the problem that involves great expense, thereby the use of these two kinds of treatment process methods is restricted, and is unfavorable for popularizing and development.
Summary of the invention
Handle the problem that exists at sulfurous gas in the above-mentioned prior art, it is simple, easy to operate to the present invention proposes a kind of not only treatment process, and the vitriolic processing method is handled and produced in good, the economical and practical sulfurous gas desulfurization of treatment effect.
Sulfurous gas of the present invention comprises hydrogen sulfide containing coke-oven gas and other hydrogen sulfide containing industrial gaseous waste that emits.
The processing method of a kind of sulfurous gas relieving haperacidity of the present invention is: the sulfur-bearing foam that is produced in earlier the sulfurous gas desulfurization being handled directly sprays into and burns in the incinerator, the sulfur dioxide gas that burns generation absorbs sulfur dioxide gas catalysis and makes sulfuric acid through after purifying, purifying.
For further improving sulfurous gas desulfurization treatment effect, the sulfur-bearing foam that the present invention is produced in earlier the sulfurous gas desulfurization being handled sprays in the drying oven drying and makes sulfur-bearing dry powder, again sulfur-bearing dry powder is sprayed in the incinerator and burn, the sulfur dioxide gas that burns generation absorbs sulfur dioxide gas catalysis and makes sulfuric acid through after purifying, purifying.
To a large amount of sulphur mud or the sulphur cream that has produced by the prior art processes desulfurization, the present invention makes sulfur-containing liquid with sulphur cream or the dilution of sulphur mud earlier, again sulfur-containing liquid sprayed into and make sulfur-bearing dry powder in the drying tower, sulfur-bearing dry powder sprayed in the incinerator to burn or directly sulfur-containing liquid to be sprayed in the incinerator and burn again, the sulfur dioxide gas that burns generation absorbs sulfur dioxide gas catalysis and makes sulfuric acid through after purifying, purifying.
Sulfurous gas acid-making process method of the present invention is handled and is made the sulfuric acid except that being suitable for hydrogen sulfide containing coke-oven gas filtration, purification, also is suitable for hydrogen sulfide containing industrial gaseous waste processing and system sulfuric acid that other industry emits.
Above-mentioned by comprising elemental sulfur, sulfide, salt and residual benzene, naphthalene and other foreign material in the dried sulfur-bearing dry powder, these S-contained substances have combustion-supporting effect when burning, thereby not only can reduce the burning cost, eliminated the pollution once more to environment of severe toxicity and carcinogenic substance simultaneously, burning back gas includes materials such as SO2, N2 and CO2.
The present invention proposes the sulfurous gas desulfurization is handled and to produce the vitriolic processing method simple, treatment effect is good, operation is also convenient, investment and land occupation area are little, economical and practical, not only simplified the technical process of refining and decomposing the sulfide industrial waste in the prior art, and alleviated sulfide in the production process to the pollution of air and production environment and to the extent of corrosion of mechanical means, or fundamentally eliminate and bury pollution and the destruction of sulfide waste material soil, both made full use of industrial waste, turn waste into wealth, reduced cost, no waste water and dregs discharging, help eliminating environmental pollution again, improved economic benefit, can be enterprise and save a large amount of environmental protection investments and running cost, brought glad tidings to Community health's development and environment for human survival.
