Description
Technical field
The present invention relates to produce with environmental energy environment protection indirect regeneration method and the anaerobic fermentation reactor of biogas.
Technical background
People's practice knowledge arrives, and with biogas bacterium (being microorganism) fermentative processing human and animal excreta, gets final product Pesticidal and sterilizing, can obtain again high-grade energy and fertilizer.According to surveying and determination, schistosome ovum is killed for 7-22 days under room temperature marsh gas fermentation condition; Hookworm ovum is 75% through 50 days mortality ratio, all dead through 93 days; Roundworm egg was through 90 days mortality ratio 75%; The Corynebacterium diphtheriae survival time is only 30 days; Shigella flexneri separated and is negative after 30 hours, and can live 17 days in general liquid manure.
Biogas fermentation device (anaerobic reactor) is of a great variety, and condition is applicable to, all can aerogenesis.Prior art is as main flow methane-generating pits such as upflow anaerobic sludge blanket reactor (UASB), internal-circulation anaerobic reactor (IC), upflow solids reactor (USR), anaerobic contact digestors, be subject to cost and technical limitation, monomer pond holds methane-generating pit and mostly only has 1000m
3left and right, Hydraulic retention time less than 20 days, and have raw material short circuit phenomenon, and all do not reach Pesticidal and sterilizing fermentation decomposition in 93 days and just ejected, to the bad adaptability of fermentation raw material, cost is high, and running cost is very high.Because the biogas residue liquid of discharging does not reach emission standard, can not realize and directly drain into natural water, large-sized biogas engineering is only applicable to periphery enough farmlands, fish pond, the biogas residue liquid that Aquatic-plant Pond can be dissolved after biogas fermentation completely.Pinghu, Zhejiang Province Bureau of Agriculture Economics (BAD) once reported a kind of annular tunnel type methane-generating pit: this pond shape bay wall has outer ring bay wall and inner ring bay wall, and twice bay wall surrounds Primary Fermentation pond.In a side of the charging mouth of pipe, between twice bay wall, be provided with a divider wall, this wall is separated the both sides at wall by the charging mouth of pipe and the discharging mouth of pipe.The top that feed-pipe one side is annular tunnel, the terminal that discharge port one side is annular tunnel, two bay wall tops are all provided with steel reinforced concrete top beam.It is located at the center of circle discharge room, only has the divider wall between one connection cylindrical interior wall and discharge nozzle, and other is the same with hydraulic type biomass pool.Design, is unfavorable for that the raw material newly entering is to approach alr mode and microorganism combined inoculation like this, and residence time is short, and output biogas pressure changes greatly, and building large methane tank lid span can be restricted.The methane-generating pit of prior art at least will, through the decomposition of thoroughly fermenting of 93 days Pesticidal and sterilizings, be difficult to accomplish as taken normal temperature fermentation raw material.The patent No. 201210216779.1 hydraulic pressure float cover type biogas generating pits, also because the technical reasons such as the large restriction of pond lid span consequently fail to apply.Obviously prior art can not meet the demand of biogas output and environmental protection.
The organic wastes such as the domestic refuse in human feces, fowl and animal excrement, stalk, weeds leaf, town and country, factory's organic sewage are fine biogas fermentation materials, except spending, by modes such as sewage work, landfills, process a part, also has the artificial arbitrarily discharge of many quilts, not only wasted resource, the environment for human survival of having gone back severe contamination.From economic angle, say a kind of processing mode of negative income.
Current biogas engineering, says that pursuing the energy is target, but people mostly are the environmental requirement of the own plant of solution, just invests construction methane-generating pit, and biogas is used as to co-production.These plants are all take grain as feed, and feeding cost is very high, only pursue the year of fowl poultry and deliver quantity economic benefit for sale, never pursue quality and the biogas output economic benefit of fowl poultry.Once feed valency liter, breeding stock reduces or withdraws, the fen " the cleverest housewife can't cook a meal without rice " of building, and many methane-generating pits fall into disuse therefrom.Producing in this way biogas output does not increase forever.From economic angle, say a kind of production biogas mode of low income.The patent No. 201310025678.0 relates to a kind of method of agricultural crop straw and the combined solid fermented production biogas of feces of livestock and poultry.
Biogas is a kind of energy cyclic regeneration clean energy.We are low using cost, output is large, stable yields, doublely control environmental pollution and pursue a goal as production, can not pursue merely Energy production, and the biogas of producing with this could petroleum replacing becomes the mankind's main energy sources source.

It should be that the active biogas residue liquid before decline appears in a large amount of microorganisms that return line takes out, and reply quantity of reflux is controlled, and at least the 10%-30% of raw material liquid measure is entered in Dagri, as raw material overrich is opened rare with the active biogas residue liquid refluxing.The active biogas residue liquid that retains a large amount of microorganisms and backflow in central opening round shape divider wall completes inoculation task jointly.
Feed reservoir liquid surface height controlling the Push And Release of discharge nozzle permanent magnet one-way cock, therefore feed reservoir will exceed opening point, the pressure that the stock liquid degree of depth is produced is greater than discharge nozzle permanent magnet one-way cock and opens the power of conducting, raw material pour enter in pond frequent, be that sweathouse stirs frequently, so one day the raw material that produces preferably send into several times sweathouse, so that feed reservoir is held is unsuitable excessive, pond holds that to be controlled at 3-10m3 just passable.
Just in case stop up by feed channel, constant pressure valve can lose pressure-keeping functions, the pressure between air storage exceedes discharge nozzle permanent magnet one-way cock and opens the power of conducting, the conducting that also can be opened of discharge nozzle permanent magnet one-way cock.
Feed-pipe will be inserted natural pond liquid in center circle tubular divider wall deeply, retains from 10cm-100cm at the bottom of pond.
Inner natural pond, U-shaped pipe pond liquid entrance will be connected to constant pressure valve under constant biogas between the air storage natural pond liquid level when the pressure value of a certain setting, and natural pond liquid entrance can be made unsteady entrance, allows scum silica frost have preferential right of ingress.
Discharge nozzle permanent magnet one-way cock consists of discharge nozzle, permanent magnet, dodge gate.The set positions of discharge nozzle permanent magnet one-way cock, to first set constant pressure valve constant biogas between the air storage pressure value in a certain setting, make it be less than permanent magnet one-way cock and open conducting power, permanent magnet the suction-combining force is greater than dodge gate self gravitation, so just permanent magnet one-way cock can be located on the pond capping of the discharging mouth of pipe, between making to import and export, produce the larger height of water.
The gravity valve that return line, the set one-way cock of feed-pipe are normally off, the dodge gate opening force of valve is less, as long as there is the liquid level difference pressure that is greater than dodge gate opening force just it can be opened.
Heating unit, can be the recirculated water of electric heating, generating oil engine or sun power, and accessible computer control, for the natural pond liquid in heating raw pond feed liquid or methane-generating pit, improves leavening temperature, can improve gas production rate, shortens the Pesticidal and sterilizing time that is less than 93 days.
This curve tunnel type methane-generating pit self air storage amount is very little, needs supporting gas-holder.
This curve tunnel type methane-generating pit, comprises divider wall, can build with Steel Concrete, also can build by mural tiles, and top adds collar tie beam, and Chi Gai builds with Steel Concrete.
