Description
Technical field
The utility model is related to arrive technical field of methane more particularly to a kind of circulating methane-generating pit.
Background technology
In rural area, the popularization of biogas is more and more extensive.According to the effect of all kinds of bacteriums in marsh gas fermentation processes, biogas bacteria
Two major classes can be divided into.First kind bacterium is called decomposer, its effect be complicated organic matter is resolved into it is simple organic
Object and carbon dioxide etc..There is special decomposition of cellulose among them, be cellulose-decomposing bacteria；There is special decomposing protein, cry
Protein decomposing dacteria；Have special lipolytic, cry lipolysis bacterium；Second class bacterium is cried containing methane bacteria, is usually methane backeria,
Its effect is that simple organic matter and carbon dioxide are aoxidized or are reduced into methane.Therefore, organic matter becomes the process of biogas,
Like producing a kind of two procedures of product in factory：It is decomposing bacteria first by complicated organic such as excrement, stalk, weeds
Object is processed into semi-finished product, i.e., compound simple in structure；Besides under the action of methane bacteria, simple compound is processed
Into product, that is, generate methane.With the development of China's biogas science and technology and the popularization of rural household biogas, used according to locality
It is required that there is the hydraulic type pond of fixed ledge with conditions, household methane tanks such as temperature, geology, take off lid hydraulic type pond, hanging tube type water greatly
Water hydraulic type pond, separation cover-floating type pond, semi-plastic type pond, Full-plastic pond and pot type are returned in pressure type pond, meandering distribution hydraulic type pond, top
Pond.Form is although varied, but sums up substantially by hydraulic type biomass pool, float cover type biogas generating pit, semi-plastic type methane-generating pit
Change what is formed with four kinds of fundamental types of pot type methane-generating pit.
Wherein hydraulic type biomass pool has lot of advantages, is mainly manifested in：Pond body structure tension performance is good, and fully
Using the bearing capacity of soil, so labor and material saving, cost is than relatively low；It is particularly substantial amounts of suitable for loading a variety of fermentation raw materials
Crop material collects manure to rural area highly beneficial；For ease of often feeding, lavatory, pigsty can be built in above methane-generating pit, excrement with
Shi Douneng is swept into pond；It all contacts with soil around methane-generating pit, has certain effect to pond body heat preservation.
Although hydraulic type biomass pool have more than the advantages of, there is also many shortcomings：Since air pressure changes repeatedly, this is to pond
Body intensity and lamps and lanterns, the stabilization of kitchen range efficiency of combustion and raising have detrimental effect；Due to no agitating device, scum silica frost in pond
Easily crust, and be difficult to crush, so the utilization rate of fermentation raw material is not high, pond holds factor of created gase, i.e. every cubic metre of one daytime of pool volume
The gas production at night is relatively low；It is big to discharge to fermentation raw material for the methane-generating pit based on stalk since removable cover diameter cannot increase
Comparision is difficult.
Publication No. CN 200943081, publication date are that the Chinese patent literature of on 09 05th, 2007 discloses a bulb
Shape methane-generating pit, it is characterised in that：It is made of pond body, feed inlet, discharge port, water pressure chamber and entrance, entrance is located in pond body
Portion, feed inlet, discharge port are located at entrance both sides, and water pressure chamber is located at discharge port top, and pond body is spherical shape.Although the patent document
Using the methane-generating pit of spheroid form, more raw materials can be packed into, to generate more biogas.But entire methane-generating pit is
Sphere shape, not only methane tank body takes up a large area, is not fixed easily, and because spherical pond body is used, when gas production is more
Gas concentration will be increased, gas concentration is excessively high easily to generate quick-fried pond phenomenon, in order to prevent gas excessive in methane tank body
Concentration is, it is necessary to the in vivo feed liquid in pond be extracted out, but can so cause again methane gas producing difficulty again, the aerogenesis cycle is longer.
