Abstract
This invention relates to a plasma tails treatment. Hot tails that contains steam and tar vapor from cokery is directly fed into a plasma gasifier to produce synthetic gas, reduced gas and fuel gas. Its procedure is short and easy to operate, has high heat efficiency and little pollution, and needs no catalyst, so as to eliminate toxic operation caused by catalyst decomposition.
Description
Technical field
The method of plasma gasification coal oven dithio-gas of the present invention relates to a kind of coking raw gas and makes with H under plasma is auxiliary
2, CO is the method for main synthetic gas, reducing gas, combustion gas, belongs to Coal Chemical Industry and plasma chemical industry category.
Technical background
The ordinary method of handling coal oven dithio-gas is: 650 ℃～850 ℃ raw gas is cooled to 80 ℃～85 ℃ at bridge tube, effuser spray ammoniacal liquor, be cooled to 25 ℃～35 ℃ again in gas primary cool workshop section, a large amount of sensible heat and wherein a large amount of water vapors, the latent heat of tar steam of raw gas is wasted therebetween, also need to consume a large amount of water coolants and ammonia simultaneously, coal gas after just cold also will pass through electrically trapped tar oil, except that ammonia, take off naphthalene, wash benzene, operation such as desulfurization, the purification coal gas that obtains could be as the raw material production synthetic gas.All there is coking chemical waste water to produce in each workshop section, also has coke tar refuse, acid tar and regenerating wash oil residue to generate in addition.When big energy is wasted, cause very overall situation pollution.
China's coke output in this year will be near 200,000,000 tons, and raw gas output will be above 1,000 hundred million m
3Only Shanxi Province's coking last year is 8,000 ten thousand tons, produce about 304 billion cubic meters of coke-oven gas, it is national West-East National Gas Transmission Project year 2.53 times of displacement, enough Shanxi urban and rural residents used 8 years, but the reasonable utilization ratio of coke-oven gas only is 8.86%, remaining directly discharges a large amount of wastes, is equivalent to the about 2,000 ten thousand tons of coals of annual loss, causes the financial loss over ten billion Yuan.Along with " progress of West-east Gas engineering, coke(oven)gas will be very rewind down go out the gas field, will cause the excessive of coke(oven)gas; how rationally, effectively utilize a large amount of coke(oven)gas; be to solve the wasting of resources, environmental pollution is with the closely-related big problem of socio-economic development.
At present, for coming synthetic ammonia, methyl alcohol, dme, the raw material production synthetic gas is considered to a good outlet with the coke-oven gas.The route of being produced synthetic gas by coke-oven gas roughly has three, and the one, partial oxidation technology, the 2nd, steam reformation, the 3rd, CO 2 reformation, three operational paths all need catalysis system.No matter which bar circuit all needs raw gas is purified, make to purify in the coal gas of back sulfide, halogen compounds, tar etc. and reduce to and equate low level.Analyse carbon, sulphur, halogen, arseniasis to prevent catalyzer.Clean coke-oven gas synthetic gas synthesizing methanol f=(H
2-CO)/(CO+CO
2) ideal conditions that is higher than synthesizing methanol is f=2.10, coal-tar middle oil steam of raw gas and lower carbon number hydrocarbons can be converted into CO under plasma effect can obtain rational f value.In addition, no matter the sort of technology all exists technical process long, and facility investment is big, process cost height, the shortcoming that energy utilization efficiency is low.
The method of plasma gasification coal oven dithio-gas of the present invention, not only can utilize the sensible heat of the raw gas that directly utilizes 650 ℃～850 ℃ and steam latent heat wherein, and be rich in a large amount of high-octane active particles (molecule of ion, electronics, atom, excited state etc.) and participate in chemical reaction, can obtain the higher temperature of chemical combustion, heating rate and gasification rate, generate CO/H
2Than suitable synthetic gas.Therefore the present invention has concentration of energy, gasification rate is fast, gasification intensity is high, flow process is short, facility compact, be easy to realize increasingly automated and pollute little, do not have the Liquid wastes generation, do not need characteristics such as catalyzer, atmospheric operation.
Summary of the invention
The purpose of the method for plasma gasification coal oven dithio-gas of the present invention is to overcome the deficiencies in the prior art, improves the energy utilization efficiency of coke-oven gas, solves problems such as existing producing synthesis gas from coal Technology Need high pressure, catalyzer and the easy carbon distribution of catalyzer, poisoning.Disclose a kind of utilize plasma body raw gas is efficient, clean, be converted into the method for synthetic gas easily.
Mainly forming (mass percent) by pit kiln coking chamber furnace roof space through the raw gas that upcast comes out is: tar steam 9%～14%, water vapor 30%～36%, crude benzol 2.5%～4.3%, ammonia 0.7%～1.1%, H
24%～10%, CH
417%～31%, CO7%～12%, N
21%～10%, CO
22%～7%.
Therefrom contain a large amount of water vapors in the raw gas as can be seen, from thermodynamic (al) angle analysis, the water vapor in 650～850 ℃ of raw gas and methane, lower carbon number hydrocarbons, tar steam have the ability that generates the higher concentration synthetic gas; Driven angle of mechanics says that speed of reaction is very slow.Water vapor and methane, lower carbon number hydrocarbons, tar steam are being rich under the action of plasma of active particle and the activation energy of oxygenousization agent reaction such as water vapour reduces significantly, and gasification reaction carries out with the speed that is exceedingly fast, and generates the H of high density
2, CO.
Based on above thinking, raw gas enters plasma gasification reactor through upcast, bridge tube, effuser.Plasma generator adopts gas such as air, oxygen, nitrogen, water vapor or their mixed gas as working gas, also can be with raw gas directly as working gas, at first infeed water coolant, working gas, vaporized chemical (water vapor, oxygen-containing gas) and raw gas in plasma generator and plasma gasification reactor during work, the working gas of plasma generator is H
