Description

Biogas production system
Technical field
The present invention relates to a kind of system of fermentation gas, be specifically related to a kind of biogas production system.
Background technology
Pig manure is a large amount of ight soil that in the process of raising pigs, pork chop is let out, and is a kind of robust fibre thing, wherein mixes a large amount of urine, mucus.Pig manure is a kind of fowl and animal excrement of not easily airing, and along with the continuous expansion of plant of China cultivation scale, what intensive culture brought is a large amount of pig manure centralization, and a large amount of pig manure is banked up and is difficult to process together.Long-term placement not only causes mosquitos and flies, and simultaneously foul smell is to surrounding environment, all cause very big pollution to underground water source, as not environmentally solved pig manure problem, not only day by day serious to the pollution of environment, also causes serious impact to the ensured sustained development development of plant simultaneously.How effectively pig manure could be processed, effectively to develop, become the most important thing problem of pig farm Sustainable development.
Along with development, a large amount of pig manure collects by people, and through research, pig manure can be used for Biogas originally, uses, turn waste into wealth for pig farm, resident family; There is a kind of system utilizing pig manure Biogas in prior art, is collected by the pig manure on pig farm, ferments in the dirty pond of collection, produce biogas, then in the upper outside connection feed channel in the dirty pond of collection, breather line adds strainer, by breather line, biogas is drawn, for people to use; But collect the fermentation biogas that dirty pond is simple, its fermentation time is longer, and the efficiency of the generation of biogas is lower.
Summary of the invention
The invention is intended to provide a kind of biogas production system improving biogas production efficiency.
Biogas production system in this programme, comprise plant and the dirty pond of collection, plant is connected by collecting dirty pipeline with the dirty pond of collection, the dirty pond of described collection is connected with homogenate acidification pool, and collect between dirty pond and homogenate acidification pool and be connected with refiner, homogenate acidification pool is connected with metering heating bath, described metering heating bath is connected with anaerobic fermentation tank, anaerobic fermentation tank is connected with natural pond liquid storage pool, and metering heating bath is also connected with natural pond liquid storage pool, and anaerobic fermentation tank is connected with step methane station by gas pipe line.
The know-why of this programme and beneficial effect are: by the ight soil of animal in plant, and be sent in the dirty pipeline of collection from plant, ight soil is sent in the dirty pond of collection through the dirty pipeline of collection, collects dirty pond and is stored by collecting dung; Be fed through in refiner by the ight soil in the dirty pond of collection, refiner is even by ight soil agitation grinding, increases the contact surface of ight soil; By refiner, be sent to by the ight soil of pasty state in homogenate acidification pool, homogenate acidification pool carries out acidifying to ight soil, acidifying is the fermenting process of a quasi-representative, the meta-bolites mainly various organic acid of microorganism, acidifying can accelerate manure fermentation, accelerates the production of biogas.
The biogas produced by fermentation and liquid enter in metering heating bath, metering heating bath measures respectively to biogas and liquid, and cutting out partial liquid, because ight soil has had portion of stool to be converted to natural pond liquid and biogas in the process of acidifying, effective ight soil accounting reduces, so need separate part liquid, improve the accounting of effective ight soil; Isolated partially liq is sent in the liquid storage pool of natural pond.
Measure heating bath simultaneously and preheating is carried out to the biogas formed and liquid, anaerobic fermentation tank is entered into through the biogas of preheating and liquid, anaerobic fermentation tank heats further to biogas and liquid, anaerobic fermentation tank is the under anaerobic stabilized formation natural pond liquid by the Metabolic activity of microorganism by ight soil, produce with biogas simultaneously, by the ight soil heated, there is certain temperature, the whole chemical reaction reaction times can be shortened, accelerate the production of biogas further, the biogas produced will be fed through in step methane station and store, the natural pond liquid produced will enter in the liquid storage pool of natural pond, natural pond liquid is stored by natural pond liquid storage pool.
Further, natural pond liquid storage pool is connected with orchard and farmland by connecting pipe, and after reaction, the natural pond liquid of formation, itself has a large amount of fertilizer element, can be used as fertilizer, applies fertilizer to farmland and orchard, more luxuriant with what make crop and fruit tree grow.
Further, also comprise Organic Fertilizer Plants, described plant is connected with the feed pipe of Organic Fertilizer Plants by transport pipe, and portion of stool enters the processing of fertilizer field, can be processed into fertilizer, add the Land use systems of ight soil, also improve the income of raiser.
Further, the escape pipe of step methane station is connected with the inlet pipe of plant, is delivered to by biogas in plant, the raiser in plant, and biogas can be used to generate electricity, and make electricity consumption to cook, lighting etc., plant can not use external source, energy-saving and emission-reduction.
Further, also comprise boiler, anaerobic fermentation tank is connected with the air flue of boiler, the water channel of boiler and anaerobic fermentation tank with measure heating bath and be connected.Biogas flows out from air passage outlet, lights biogas, heats boiler, and boiler will heat water, and hot water will be sent in the heat-exchanger rig of metering heating bath and anaerobic fermentation tank, and the heat of water, by heat-exchanger rig, carries out heat exchange with biogas and liquid.
Accompanying drawing explanation
Fig. 1 is the structural representation of biogas production system embodiment of the present invention.
