Description
Technical field
The invention belongs to offal treatment and development of clean energy field, be specifically related to a kind of system of carbon dioxide zero discharge type organic waste recovery energy.
Technical background
It has been undisputable fact that the transition development and utilization of fossil fuel causes global warming, acid rain and environmental destruction and degeneration, and fossil fuel also is faced with the situation of exhaustion, therefore consider based on the environment and the energy that the mankind press for a kind of regenerative resource that does not have pollution.Hydrogen Energy is the renewable alternative fuel of a kind of desirable cleaning, only generates water after its burning, does not have other greenhouse gases, can directly be converted into electric energy efficiently by fuel cell.Consider that from the angle of environment utilizing various organic wastes to carry out anaerobic fermentation hydrogen manufacturing is in recent years a big research focus, and is considered to most possibly take the lead in realizing the commercial applications bio-hydrogen production technology.
The organic substance that the Biochemical Mechanism of anaerobic fermentation hydrogen manufacturing has determined to carry out hydrogen production through anaerobic fermentation mainly is carbohydrate raw material such as carbohydrate, starch and cellulose family, and protein and lipid difficulty are carried out hydrogen production through anaerobic fermentation; And, follow the formation of accessory substances such as various small molecular organic acids and alcohols in the time of the carbohydrate fermentation and hydrogen production, can not be converted into hydrogen fully.More than two reasons cause the energy recovery efficient of organic waste anaerobic fermentation hydrogen manufacturing and organic utilization rate lower.For this reason, usually adopt the technology of anaerobic fermentation co-producing hydrogen and methane to improve energy recovery efficient, at first utilize organic waste to carry out hydrogen production through anaerobic fermentation, utilize product hydrogen residue (to comprise protein, each seed amino acid, lipid again, and the product hydrogen accessory substance of carbohydrate such as organic acid, alcohol) carries out anaerobic fermentation methane, promptly traditional biogas fermentation.
When the biogas conduct finally utilized form (as direct burning), on the stricti jurise, it was not a clean energy resource, even because the biogas (methane) after purifying still can be to the airborne release carbon dioxide after burning utilizes.Therefore, the mode of utilizing that cleans most is that biogas is converted into electric energy utilization.Yet, no matter be anaerobic fermentation hydrogen manufacturing, still biogas fermentation+marsh gas power generation, all follow the generation of carbon dioxide, recovery energy process from whole organic waste, have only carbon dioxide absorption, fixing, utilization again, be only carbon dioxide zero discharge type organic waste recovery energy system truly.
Except hydrogen and biogas, the product of organic waste anaerobic fermentation also has natural pond slag and natural pond liquid.Slag common as fertilizer sources in natural pond utilizes, and when being applied to food plant (cereal crops, orchard, vegetables etc.), need carry out deep processing to remove the noxious material (especially heavy metal) in the slag of natural pond, and this moment, the processing cost of natural pond slag was higher.If during as the fertilizer of non-edible plant (as energy grass), need not to carry out deep processing can directly use, and still, does not also have the correlative study report of natural pond slag as energy grass planting fertilizer at present with the natural pond slag.Natural pond liquid is usually as liquid fertilizer or agricultural irrigation water, but contain materials such as abundant nitrogen, phosphorus, metallic element in the liquid of natural pond, and the unit are soil is limited to the admittance ability of these materials, when not having enough soils to admit natural pond liquid, excessive natural pond liquid discharging can be polluted local environment on the contrary.On the other hand, little algae is when utilizing carbon dioxide to carry out photosynthetic growth as carbon source, need nutriments such as nitrogen, phosphorus, potassium, trace element, vitamin, and these materials Main Ingredients and Appearance of natural pond liquid just, therefore, the processing of natural pond liquid and little algae stabilizing carbon dioxide can be combined, still, also not have the correlative study report that natural pond liquid is handled and little algae stabilizing carbon dioxide (coming from the organic waste anaerobic fermentation) is coupled at present.
At present, has only independent organic waste anaerobic fermentation hydrogen manufacturing research, independent organic waste biogas fermentation+biogas power generation technology, independent carbon dioxide absorption, fixing, utilization research (carbon dioxide in little algae fixed air or the thermal power plant's flue gas) more both at home and abroad.The carbon dioxide zero discharge type organic waste recovery energy system that multinomial technology such as anaerobic fermentation hydrogen manufacturing, biogas fermentation, carbon dioxide absorption, little algae stabilizing carbon dioxide, the processing of natural pond liquid, energy grass planting are gathered, and this system can obtain hydrogen and two kinds of clean energy resourcies of electricity simultaneously, and such system has not yet to see report.
Summary of the invention
