Description
Technical field
The utility model belongs to fermentation technical field, and in particular to a kind of methane/hydrogen coproduction organic fertilizer integration fermentation
Device, for low-order coal such as lignite, peat fermentation and hydrogen production gas/biological methane and fermentation production high humic acid organic fertilizer.
Background technology
Lignite（Also known as bavin coal, Lignite；Brown coal）, it is that degree of coalification is minimum rich in organic matter and humic acid
There is coal distribution to concentrate, and bury shallow, the features such as easy exploitation.By taking China as an example：Existing explored lignite resource reserves 130,300,000,000
Ton, accounts for nearly the 13% of national coal resources gross reserves, is mainly distributed on east Inner Mongolia, Yunnan and 3 provinces of Northeast China.Wherein, only Inner Mongol
The lignite reserves of ancient east just account for national lignite gross reserves more than 70%, Zhalainuoer coalfield, Ping Zhuanyuan such as east Inner Mongolia
Golconda coalfield, huolinhe coalfield, black nit coalfield, Yi Min rivers coalfield, wild goose coalfield, exhale with Nore coalfield and Shengli Coalfield,
Lignite reserves are more than 1,000,000,000 tons, suitable for strip mining transformation, so as to significantly reduce the security risk of Lignite Mine and cost.
Lignite moisture is up to 30-50%, and calorific value is low, easy-weathering and spontaneous combustion, combustion power generation are that the main of present lignite utilizes hand
Section since lignite usually contains higher moisture, is not easy to long distance transportation, and lignite is mainly used for electric power stations near coal-mines power generation.It is but brown
The thermal efficiency is lowly larger to power plant's device loss when the non-upgrading dehydration of coal is directly burnt, and also has seriously polluted the environment, and lignite
High water cut causes the transformation dryness dehydration link before burning（Moisture is reduced to less than 10%）Add cost of electricity-generating.If lignite is made
For raw material trans-utilization, and it is subject to High water cut, high limitation containing ash.Therefore, the country of petroleum resources abundance, seldom scale exploitation
Utilize lignite.So the method for the more clean on-fuel application lignite of development is efficiently to utilize the effective of the low orders coal resources such as lignite
Approach.
Microorganism conversion may be the best method of the low-order coals trans-utilization such as lignite, lignite, the peat of High water cut
Etc. low-order coals need not be dehydrated or dry, biological methane is converted into the help of microorganism（Also known as biogas, biology are natural
Gas, CH4）, hydrogen, high humic acid organic fertilizer etc..At present it is known that higher plant coalification is peat, lignite, bituminous coal and nothing
The different times of bituminous coal all constantly have coal bed gas（Gas, main CH containing methane4）It generates.Existing research report shows that lignite passes through
After microbial degradation, fulvic acid content increases, and humic acid chemism is enhanced, and can improve soil, promotes farming
Object is grown, meanwhile, it may additionally facilitate absorption of the plant to nutrients such as nitrogen, phosphorus, potassium, be rare plant growth regulator.
The microorganism conversion of lignite is the same as using compared with traditional commercial conversion, having, low energy consumption, conversion condition is mild, transformation efficiency
The advantages that high, economic benefit of converted product and application value are high, equipment requirement is simple is to realize that the energy is benign, sustainable development
The new way of exhibition.
Microorganism conversion, either hydrogen producing or biological methane, high humic acid organic fertilizer be required for suitable temperature, pH,
Suitable carbon-nitrogen ratio, microorganism species.Microbial growth, metabolism, conversion reaction process in, in certain temperature range,
Reaction rate during low temperature is low, and reaction rate is high during high temperature, can not outside the colder unfavorable fermentation of northern weather or even winter room
Ferment, this be the fermentation of the outdoor progress such as biological methane/hydrogen and organic fertilizer fermentation put into practice industrialization promotion the Inner Mongol,
Heilungkiang Deng Han areas urgent problem to be solved.Therefore, bioreactor of the exploitation with efficient heat transfer heat-insulating property is used to keep
Fermentation temperature, shortening fermentation period, extension fermenting and producing time limit are just particularly important.
Humic acid plays the role of more, improvement soil physical and chemical property, culture fertility in production.Make punching when humic acid fertilizer to apply
Or soil, when applying, it can also improve soil, improve fertilizer efficiency.Because humic acid organic colloid in humic acid fertilizer and the calcium in soil from
Son combines to form cotton-shaped gel, and this colloid is good binding material, soil particle cementation can be got up, make water stability in soil
Crumb structure increases, so as to improve the water of soil, fertilizer, oxygen, hot situation.Humic acid can provide nutrient for crop simultaneously.It should
Fertilizer can absorb the fertilizer point such as ammonium ion, potassium ion, calcium ion, magnesium ion, zinc ion, moreover it is possible to the free iron in acid soil
Ion, aluminium ion form iron, aluminium complex, reduce phosphorus fixation, improve utilization rate of fertilizer.And humic acid can promote microorganism
Breeding with activity.Humic acid has stimulation to microorganism, improves the mobilities such as fungi, bacterium and nitrogen-fixing bacteria, promotees
It is decomposed into organic matter, accelerates farm manure decomposed, promote the release of quick-acting nutrient.Existing solid containing humic acid water-soluble fertilizer
Humic acid content is 3.0% or so in product, and humic acid content also has further increase in solid product containing humic acid water-soluble fertilizer
Add space, the raising of humic acid content has more important meaning for production activity.
In existing installation for fermenting, all there are certain shortcomings.Patent（200810246603.4）Disclose one
The device of kind fiber wastes two-stage fermentation co-producing hydrogen and methane, for producing hydrogen and methane, which needs production hydrogen anti-
