Description

Fermenting tank for treating garbage

(1) technical field:

The present invention relates to the methane-generating pit of the thicker organic matter fermentation of particle in a kind of marsh gas fermentation pool, particularly domestic waste.

(2) background technology:

Sharp increase along with urban population, becoming increasingly abundant of material life, also produced a large amount of domestic refuses in the city, the application biogas technology is handled the sanitary sewage in the city at present, obtained suitable technological contribution, can use state-of-the-art internal recycle (IC) anaerobic reactor, but in handling domestic waste, because the organic particle in the rubbish is thick, and include a large amount of inorganics compositions, but can not use (IC) anaerobic reactor handles, be applied to the biogas technology in the treatment of urban garbage at present, still there is not great technological breakthrough, how it improves the thick organic fermentation rate of particle if having, shorten the dwelling period that the thick organism of particle ferments in the pond, and a large amount of inorganicss problem of go-no-go how, owing to failing these problems of adequate solution technically at present, cause in the processing of domestic waste, often adopt the method for landfill and burning, cause polluting the second time of soil and air, and in the application of biogas technology, still rest on the application on these two kinds of base pool types of hydraulic type and cover-floating type methane-generating pit, or on these two kinds of base pool types, carried out some improvement, its basic condition is as follows:

1, hydraulic type and cover-floating type methane-generating pit: be two kinds in the unified three kinds of base pool types stipulating of Chinese Government, the production of hydraulic type biomass pool collection biogas, deposit, be used on the pond body structure, have antagonism recoil many defectives that pressure produced of storing up in the biogas with feed liquid, the cover-floating type methane-generating pit is on hydrostatic basis, it is improved with the antagonism recoil defective that pressure caused of feed liquid to overcome the interior storage of biogas, significant advantage is to increase useful volume, increase fermentation rate with the increase of unit volume, but these two kinds of pond types are spontaneous fermentation, the spontaneous fermentation organism decomposes in the natural pond and to produce the whole process dwelling period of biogas longer, the thick more dwelling period that then ferments in the natural pond of particle is long more, so in handling domestic waste, because the rubbish day output of every day is especially big, and the organic particle in the rubbish is thick, methane-generating pit is as the garbage treatment quantity by a day, it need measure 40 times of minimum increases by this, it is too high to have caused cost to drop into, and benefit is too low, and must finish the go-no-go work of institute's organic/inorganic substance in the rubbish earlier, and this part needs great amount of manpower and be specifically designed to the mechanical facility of go-no-go.

2, improved pond type on hydraulic type and cover-floating type methane-generating pit basis: for example notification number is 2343170, name is called automatic stirring cover-floating type methane-generating pit, notification number is 2322971, name is called the methane-generating pit agitator air, notification number is 2358081, name is called the solar biogas producer, and notification number is 2269394, and name is called a kind of solar-energy methane pit.These four kinds of improved pond types all are improved on the basis of hydraulic type and cover-floating type methane-generating pit, the typical technology that is shown is for stirring feed liquid and heating feed liquid, on with respect to original basis, fermentation rate improves, but these two kinds of The Application of Technology, separated on a pond body often, if the special processing that is directed to domestic waste, these two kinds of The Application of Technology still are short of to some extent.Only use stirring technique, for the thick organism of particle in the rubbish, fermenting speed can change to some extent, but effect can be very not big.Adopted the fermentation rate effect of heating technology to be higher than stirring technique, but we are when the utilization heating technology, often adopt natural resources, heat as sun power, be subjected to the restriction of natural condition, under the situation that has natural condition to exist, we just can take heating technology, and in case after night or wet weather, snow sky lose the natural condition that the sun heats owing to do not take heat preservation technology, equally can be very fast turn back to spontaneous fermentation under the normal temperature.Again owing to not taking heat preservation technology, even the condition of heating is not very big but heat effect under the situation of heat radiation relatively.Moreover improved pond type, in the processing of domestic waste, be directed to the thick organism of particle, the technology that it is not crushed to desirable fineness is used, be directed to than volumetrical and be limited, do not heated the application that combines with heat preservation technology, be directed to and include a large amount of inorganicss in the rubbish, less than on the body structure of the pond of methane-generating pit, the technology application that precipitates and suspend and unify go-no-go.Therefore how effectively handle on the domestic waste, both having made is the pond type that improves to some extent, and can not be applied to completely in the processing of rubbish, and these improved pond present great majority of type can only be to be applied on the rural energy construction.

(3) summary of the invention:

The invention discloses and be directed to the thick organic fermentation vat of particle in the domestic waste specially, according to improving the needed full terms of organic matter fermentation rate, according to the various inorganicss that include a large amount of compositions in the domestic waste the go-no-go requirement that must carry out, on the body structure of the pond of a fermentation vat, designed pulverizing, stirred, heated fermentation, the technology of heat-preservation fermentation, go-no-go inorganics used.

The charging pond that the present invention adopts is circuitous shape design, and the water level in charging pond is higher than fermentation vat feed liquid water level, the drainage end opening

shape, a special pulverizer of pulverizing organism and suspended substance is installed, in crushing process, sense of rotation by Disintegrating knife, driving feed liquid moves in circuitous shape charging pond by same direction, the suspended substance of organism and inorganics is constantly pulverized by blade, until reaching the trickle degree of ideal, and in continuous crushing process, the motion of current can accumulate in the various throw outs of inorganics the place, the bottom of a pan of draining bottom suitable for reading, put a drainage sediment dish on the bottom of a pan, be used for the unified inorganics throw out of collecting, collect and approach to drain when suitable for reading, the taking-up of sediment dish is cleaned out the inorganics throw out, replace again and collect the inorganics throw out, through organism or the inorganics after the quilt pulverizing, open and drain piston bush suitable for reading, have and be equivalent to the feed liquid of useful volume more than 1/10th, wherein also include the inorganics suspended substance, because the height of water forms downward along the ballistic surging force of right cylinder pond body periphery, impact feed liquid in the fermentation vat, drive whole pond feed liquid under impact force action, formation rotatablely moves along the vartex of pond body circumferential edge, produce and stir feed liquid automatically, for continuity stirs, when heating, can from material-output tank, draw water again and enter the stirring feed liquid that discharges water in the charging pond every one hour; The fermentation vat that adopts is inside and outside pair of courage design, inner bag Chi Kou is open-air Chi Kou, seal after forming the space between inner bag and the outer courage, the sealing back is extracted the air in the space out, make it to become vacuum, the outer wall and the inwall of two courages are coated waterproofing unction, make underground water and inner bag water liquid can't seepage in two courages space, the pedestal of a concrete and bar construction is arranged at two courages bottom, the inner bag bottom is a pan bottom shape, between the contacting of inner bag bottom and pedestal, pad upper glass cotton or ore deposit scutching cotton, 50cm position inwall is coated black paint under the open-air inner bag Chi Kou, Chi Kou is last to be covered with the double-layer transparent plastic film that charges into air, make the space under the Chi Kou form a solar energy greenhouse, the inner membrance double as is collected biogas, having an airway to connect gas on the Chi Kou goes out outside the pond, inner bag bottom between inside and outside two courage spaces, enclose inner bladder outer wall have one high for 1.5/5ths places, body bottom, pond, wide is the vapor seal circle of 8-10cm, there are four tubules to pass the through ground of sealing of inside and outside two courages in the vapor seal circle, four tubules are respectively the steam ingress pipe, the fly rod pipe, drinking-water pipe, the vapor pressure vapor pipe, in cement system glass mirror concentrating solar steam kitchen range of design on the ground on Kao Chikou north (sun power steam kitchen range is not in the present invention's design) by useful volume 2/10ths unit squares, generally in 2-3 square metre of daylighting area, power is about about 1 kilowatt, optically focused on the solar cooker is disposed a steam pot, steam pipeline is connected to the steam ingress pipe in the vapor seal circle, this pipe end opening is on sealing-ring top, steam is imported in the vapor seal circle, the fly rod pipe is in the tubule, be inserted in a tubule that float and fly rod are arranged again, when the cold back formation of steam chance water liquid accumulates in the sealing-ring bottom, can be observed the height that water liquid accumulates by the rising of floating pipe.When needs draw water, can draw water by the drinking-water pipe that straight cutting be gone into the bottom, the vapor pressure vapor pipe interior be straight tube, on the ground suitable for reading has a pressure valve, when the vapor pressure of sealing-ring during greater than the pressure valve that limits, the automatically outside steam discharge of steam impulse pressure valve.On the unitized construction that forms like this, utilize solar heating that dual mode is arranged, a kind of is that the steam of light concentration type solar cooker heats in the vapor seal circle of inner bag bottom, effect is the highest, when the temperature of fermentation vat bottom feed liquid raises, the density of water diminishes, water liquid rises automatically, and on the low side relatively at the water liquid temp on top, the density of water is bigger, and water liquid descends automatically in heating the bottom, by this thermal siphon phenomenon, constantly cause circulating up and down of water liquid, evenly feed temperature can also form biogas bacterium and organic effective mass transfer process simultaneously.Another kind is the transparent double-layer plastics film that is covered on the Chi Kou, form the solar energy greenhouse on the Chi Kou, daylight directly penetrates film, the heat absorption thing is formed at the Chi Kou top by blacking, or daylight directly heats in the feed liquid water surface, and the heat transfer by heat absorption thing and water liquid level heats to feed liquid, and at every interval one hour, the impact force action that discharges water by charging stirs feed liquid, makes the temperature of whole feed liquid even.And under the situation that can not utilize solar heating, a large amount of biogas deposits of methane-generating pit output are got up, can be used as at night or wet weather, snowy day, directly use biogas as energy burning vapor boiler, producing steam heats in the vapor seal circle of inner bag bottom, and under inside and outside pair of courage vacuum structure, heat insulation down at the bottom thermal insulation material, under mouth upper part of double plastics film airspace, pond, simultaneously at night or wet weather, when snowy day, free air temperature reduced, mulching straw on film again, the cotton class improves the insulation measure, makes the periphery in its full pond that good insulation measure all be arranged, and can increase to greatest extent first to heat effect, second can temporarily not heat under the situation, reduce heat dissipation capacity to greatest extent, in addition, ferment because the various suspended substances of inorganics together enter in the pond together with organism, after date when certain fermentation, organism be decomposed and output biogas, cause a large amount of inorganics suspended substances to be collected in the water liquid level, by the fermentation process produced separation automatically.When needs are cleared up, after can all extracting the biogas under the last plastic envelope of Chi Kou out, opening coating film all exposes Chi Kou, just can clear up suspended substance in the charging pond, and then cover plastics film on the Chi Kou, in the floating thing that cleans out except that a large amount of inorganicss, also have a spot of some organism that newly enter into the pond, at this moment in the charging pond, clear up again, and do not need 100% cleaning, after the cleaning residue in the charging pond is put into fermentation vat again, organism is fermented again, isolate inorganics behind the organic matter fermentation again.Employing is in the pipeline of discharge nozzle, set up an energy straight cutting go at the bottom of the pond in movable scum pipe at the bottom of the vortex cordis, at the certain all after dates of fermentation, organism is long-pending many more along slag in the pond, need clear up it, interim insertion activity scum pipe makes it under the downward impact force action of the rotation that the charging drop produces, the organism sediment at the bottom of the whirlpool in the pond that can stir and get excited is rejected in the material-output tank through movable scum pipe and precipitates.Material-output tank divides two pond conjoined structures, and one is detritus pool, and one is the pond, can clear up the mud of post precipitation in detritus pool, and silt fertilizer can be converted into efficient organism fertilizer product.The capacity in pond is consistent with the capacity in charging pond, but in the water liquid suction charging pond, application capable of circulation, when not needing to clear up sediment, again can extraction activity scum pipe, avoid the organism and the biogas bacterium of fully fermenting have not excluded yet.

The principle of work of this fermenting tank for treating garbage is as follows: rubbish is poured in the charging pond, utilizes the water-based principle precipitation and the two kinds of materials that suspend out, and suspended matter is smashed by pulverizer.Sedimentable matter is brought in the sediment dish by current and is assembled, pulverize organism later, no longer particle is thick, but uniformity trickle very, open and drain piston bush suitable for reading, all suspended matters all impact and enter fermentation vat, and the rotation that is formed the feed liquid vartex by surging force is stirred, and all throw outs are separated, in the sediment dish in charging pond, can take out the dish cleaning, after suspended matter enters fermentation vat, under the effect of organism composition biogas bacterium in the pond wherein, be decomposed and produce biogas, a part becomes the organism sediment and is deposited at the bottom of the pond, and a part is converted into and floats on the biogas under the mouth plastics gas bag of pond, is discharged to outside the pond by airway and lays in.Organism in the suspended matter is decomposed after the fermentation, and remaining is exactly the suspended substance of inorganics, and the biogas bacterium can not be degraded it, and that is concentrated is suspended in the feed liquid surface, and the separation that inorganics is not degraded is born in natural birth in the pond.When have the sun daytime, solar energy greenhouse on concentrating solar steam kitchen range and the Chi Kou begins the work of heating, by vacuum between the inside and outside pair of courage, double-deck air plastics gas bag on the Chi Kou, thermal insulation material at the bottom of the pond, make and be with good insulation measure outside the full pond, heat radiation is lowered to bottom line, also heat and farthest improved, made full use of and heated the energy, when losing the sun utilization of resources, the biogas that utilizes methane-generating pit itself to produce, the steam boiler on the heating solar cooker continue to produce steam and heat feed liquid.Steam by airway under vapor pressure, being pressed in the outer sealing-ring in inner bag bottom of nature, meet when steam and to form water liquid when cold and accumulate in sealing-ring, can judge the height of ponding automatically by a fly rod pipe, when ponding reach a certain height, can discharge moisture content by drinking-water pipe, the pressure of storage progressively rises when reaching pressure valve qualification pressure in steam is in sealing-ring, can outwards discharge steam automatically by vapor pipe, under the measure of heating, feed liquid progressively can be warmed to the highest leavening temperature, reach and shorten the dwelling period purpose that organism ferments in the pond, increase in temperature is during to the leavening temperature set, and heating at this moment becomes the balance of replenishing radiated energy, according to the setting of leavening temperature in the pond, can draw biogas output every day under design temperature, by the size of biogas output, it is much to draw useful volume every cubic metre of decomposing organic matter dry-matter every day deal, also is that fermentation vat is by the useful volume organism throughput capacity of every day.In a domestic waste, by organism proportion amplitude, organism moisture content amplitude, how many organism dry-matteies can calculate has in 1 ton of rubbish, the two-phase combined cover is calculated, and can draw a methane-generating pit by the useful volume domestic refuse throughput capacity of every day.When needs cleaning inorganics scum silica frost, with vacuum fan plastics film is covered biogas down all after the extractions, open the plastics gas bag and expose Chi Kou, from Chi Kou, directly clear up, cover again after cleaning out and go up the plastics gas bag, when needing cleaning organism sediment, center of vorticity at the bottom of the through pond of insertion activity scum pipe from discharge nozzle, under the impact force action of charging, sediment is discharged in the material-output tank precipitates, when needs charging treating refuse is stirred feed liquid with needs, can from material-output tank, draw water into the charging pond, water liquid recyclability is reused.

The advantage of this fermenting tank for treating garbage is: two specific characters are arranged in the municipal wastes, and the one, organic particle is thick, and the 2nd, contain a large amount of inorganics compositions.The thick fermentation period that causes of particle is long, and then useful volume is big relatively, the input cost height.Artificial or the mechanical go-no-go of a large amount of inorganics compositions before need fermenting, even but go-no-go also can't 100% cleans out the inorganics composition, and cause inorganics residual in fermentation vat, accumulate for a long time and occupy useful volume, make fermentation vat ineffective.Because this two specific character in the rubbish, make biogas technology be difficult to be applied, this pond is in conjunction with this two specific character, on the structure of methane-generating pit, transform, and increased again and heated and heat preservation technology, shorten the fermentation period of organism in the pond as much as possible, useful volume is fully utilized, reduced cost first, reduced special inorganics go-no-go work, second improved the use value and the utilization benefit of methane-generating pit, biogas technology can be applied in the treatment of urban garbage, and be applied widely.
