Description

Non-failure biogas fermentation tank

Affiliated technical field

The present invention relates to one group at the pig farm, especially big-and-middle-sized scale pig farm " three wastes " harmless treatment must tool large-scale production facility---marsh gas fermentation pool is optimized improvement design, build long-term normal operation non-failure biogas fermentation tank and the biogas that makes full use of " three wastes " a large amount of associations in innoxious downstream, natural pond pool resource, prolong the industrial chain of raising pigs, develop a circular economy, valuable resource is moored in deep processing biogas, natural pond, produces the new technology of " biogas liquefied fresh fuel " and high-quality " biological (green) compound manure " production method.

Background technology

One, current being widely current built up in town and country or at " typing " marsh gas fermentation pool of building, especially big-and-middle-sized marsh gas fermentation pool with regard to its structure design, also has perfect not to the utmost place.Than distinct issues be: fen appearance " skinning " fault that is in operation, can't handle, have a strong impact on normal feeding, gas deliverability descends even has to and stops production.Methane-generating pit " skinning " origin cause of formation is the some colloidal substances thing that produces in some light matter matter and the microbiological deterioration fermentation material organism process in the fermentation material, carried secretly by biogas bubble and to float, floating knot is on liquid surface, natural pond, these " skinning " are subjected to high temperature action in the fen again, can not be with degrading completely natural pond pool coprecipitation bottom the fen, outside the discharge fen, long-pending more thick more, it is stuck to harden at last.Only stop to produce, difficult axe is opened capping plate in the fen, and not coolie's strength digs skinning thing and precipitation natural pond, whole pond pool clearly to come up, and clears up facility again, and production again feeds intake.Marsh gas fermentation pool is the pig farm recovery of three wastess(waste gas,waste water and industrial residue), one of the main large-scale production facility that must possess of developing a circular economy, and the good rust of its function, direct relation production efficiency is worth paying close attention to diligently.

Two, pig industry is dismissed as the industry of structural pollution environment, many pig farms, current town and country all are the extensive modes of production, how can not effectively dispose human and animal excreta, the sewage of all a large amount of outputs every day, also have dressing, dead porkling, dead packing sow, dead mouse or the like putrefactive organic matter rubbish, cause local productive life ecological environmental pollution very serious.Only cite an actual example: medium-scale pig farm, certain county, above-mentioned rubbish thing is mound storage everywhere, let alone to reveal empty fermentation and give birth to moth, near only waiting for the common people come only with 40 yuan of knockout prices per ton, also to beg other to buy back, because corrupt moth, the too stench of giving birth to of dung heap when farm manure usefulness, be willing to that the people who buys is few, because of can not timely and effectively disposing, make local environment, the air stench, mosquitos and flies density extra-high-speed, disturb the people and be much troubled, a large amount of that toxic sewage (cleaning the high malicious sterilization sewage of swinery) is discharged the flood irrigation face of land, soak into body of groundwater, pollute the peripheral common people's beverage well, pollute the farmland, downstream, the clay fertilizer element is unbalance, the prominent long lodging underproduction of rice standing grain even mistake are received, and also often cause the fish farm, downstream to poison the fish accident in a large number with poison.(have one group on the spot the contaminated live photo of environment for according to).The common people so right-safeguarding fight mood are very fierce, affect local government, affect local Party Committee, concern very nervous.Pig industry does not solve environmental pollution, and is hopeless.In fact, society is progressive to today, many with serious pollution pig farms, owners are subjective, also be willing to get along amiably and peacefully with the peripheral common people, also be willing to unload environmental pollution pressure, understand that also the pollutents such as ight soil of pigs can alleviate environmental pollution and bear a heavy burden with the method for fermentation methane production, but objectively, owners also have many helpless, and that is exactly: " skinning " stuck fault easily takes place especially big-and-middle-sized marsh gas fermentation pool can't handle, and controlling " three wastes " needs bigger person property to drop into, may not be certain has very good economy return, also have full dose processing every day dirt, a large amount of biogas is all arranged every day, a large amount of natural pond pools are discharged, and but do not have the method for effectively utilizing.For example: through measuring and calculating: one 3000 medium-sized kind pig farms, pollution treatment drop into to need hundreds of thousands of unit, and every day, all full dose was handled the dirts such as ight soil on the same day, and every day can both more than 2,000 cubic metre of biogas of output, also more than ten ton of natural pond pool of output simultaneously.A large amount of biogas like this, pig farm itself is used for illumination, life fuel etc., only consume outside the sub-fraction (about hundreds of cube), all the other have a large amount of extremely biogas not use, the inconvenience use of seeing out at a distance again, see its bubbling race Heaven in vain, moreover also having so a large amount of natural pond pools to handle, be still the very farm manure of low value.Raise pigs the owner not because of the recovery of three wastess(waste gas,waste water and industrial residue) laboriously obtains too many economy return, the enthusiasm which comes? wanting the essential contaminated solution of owner, is trend of the times, as be passive and for it sound of sighing! The pig farm, develop a circular economy in especially big-and-middle-sized scale pig farm, and where is the road? workers do not know how to say it, and managers also speak more unclear.Too worth motive has been paid close attention to.

In sum, issue in focus is to solve the technical problem that must solve in the pig industry recycling economy to a bit.Why pig industry exists is wanted cyclic production, is that the Swine Production process all has a large amount of putrefactive " three wastes " outputs such as ight soil dung urine sewage dirt that influence environment every day, is the contaminated source of pollution of environment.The all necessary full dose " innoxious " of " three wastes " of every day is handled complete, is the bounden social responsibility of pig farm owner.Solving " three wastes " innoxious unique method is " three wastes " full dose fermentative processing, also is the chance that pig industry turns waste into wealth.Becoming " three wastes " resource into utilizing, how can these refuses be become into the dotey, then is the duty-bound necessary satisfactory test paper that must hand over of scientific and technical research.
