Description
Technical field
The utility model relates to a kind of biogas production device that combines with organic fertilizer production, especially a kind ofly utilizes biological compost fermentation heat production to heat, and guarantees that biogas continues the device of producing.Belong to countryside wastes recycling and new energy development field.
Background technology
The biogas production technology is promoted for many years in China, is mature on the whole at vast southern area, and is widely used.And in the northern China most of areas, particularly year February in annual November to the second the period average temperature be lower than area below-10 ℃, annual normal gas producing can only be kept 3-4 month, biogas technology is promoted and is also had great difficulty.The methane-generating pit of China's widespread use is at present built technology and mainly is divided into three kinds of hydraulic type, cover-floating type and gasbag-types, and perhaps developing on this basis many new forms.Because the waste water that is used for biogas fermentation is high concentrated organic wastewater, it is bigger to deal with difficulty.With the hydraulic type biomass pool is example, and because of its cost is lower, the pool wall resistance to pressure is good; Do not take aboveground space, become China and use maximum biogas production patterns, shortcoming be methane-generating pit is embedded in underground; Temperature receives ectocine bigger in the pond, and temperature is difficult for improving, and microbial activities is inactive.In addition, natural pond liquid, natural pond slag cleaning work are convenient inadequately, and input and output can not be directly proportional.Therefore the methane-generating pit of the regional this form of a part has been lost using value by idle or discarded in the north.Cross low problem for solving temperature; Many novel temperature raising and maintaining methane-generating pits also appear at present; These marsh gas ponds are on original methane-generating pit basis, to adopt measures such as temperature controlling instruments, sun power to cross low problem to solve north of china in winter methane-generating pit temperature; But, make that also these new techniques can not large scale application because its cost is higher.Therefore, increase the methane-generating pit temperature, easy and simple to handle in management, low cost, high production, the use value of raising methane-generating pit becomes the primary problem that solves of present methane-generating pit construction.
Summary of the invention
The purpose of the utility model is can not proportional problem for solving northern current biogas production input and output; That is: because the low biogas of winter temperature can not continuous production or the high technical barrier of continuous production cost, and a kind of biogas production device that combines with organic fertilizer production is provided.
The purpose of the utility model realizes through following technical proposals: a kind of biogas production device that combines with organic fertilizer production; It comprises perimeter walls (5); Establish spice district (7) and software fermentation bag (1) in the perimeter walls (5), the top of software fermentation bag (1) is provided with methane outlet (4); Both sides are set up discharge port (3) and opening for feed separately, and opening for feed and charging pond (2) join.Above-mentioned software fermentation bag (1) places on the support frame (6), and leaves the space with perimeter walls (5), and organic fermented product is filled in this space; Above-mentioned spice district (7) is provided with slope (8) with convenient work.
Software fermentation bag described in the said apparatus belongs to the anaerobically fermenting pond; Feces of livestock and poultry is mixed with agricultural crop straw, rice husk etc.; Processing organic fermented product after stirring and be arranged in the outer bottom of software fermentation bag and all around, is that biogas production provides heat through aerobic fermentation.Livestock and poultry liquid dung is injected in the software fermentation bag, carry out biogas production, the natural pond liquid that is produced is regularly extracted out; Be sprayed onto on every side on the fermented product; The natural pond slag and the above-mentioned fermented product thorough mixing of discharging add in the fermentation heap again, make it for the software fermentation bag enough heats are provided incessantly.
The unloading phase organic fermented product composition be with feces of livestock and poultry and agricultural crop straw, rice husk etc. with 1: 3 mixed, regulate moisture to 60% to 70%, add the bottom of software fermentation bag and all around after stirring in order to.Through anaerobically fermenting normal gas producing after 20 days, and natural pond liquid regularly extracted out, be sprayed onto on every side on the fermented product, excess moisture oozes out through ground, and organism stays in fermented product relaying supervention ferment; The natural pond slag and the above-mentioned fermented product thorough mixing of discharging add in the fermentation heap again.The bottom is processed fertilizer with organic fermented product all around after fermenting after a while.
In the described biogas production device, software fermentation bag opening for feed is fixed on the perimeter walls, and discharge port will go up and down freely, lifts when producing biogas, puts down during the slag of row natural pond.Discharge port place configuration lift pump, and have filtration unit.
In the described biogas production device, main body methane-generating pit top is guaranteed that methane-generating pit can obtain enough heats, and is played the effect of insulation according to sun altitude design plastics brooder or other insulation ceiling.
The characteristics of the utility model are simple in structure, and are scientific and reasonable, applied widely, when producing biogas, produce the high-quality fertilizer again, both saved the space, solved on the low side and liquid natural pond, the natural pond slag emission problem of north of china in winter biogas production temperature again, two at one stroke.Compare with existing pattern, adopt this device, less investment, income is big, aspect daily administration, handles liquid natural pond, natural pond slag and becomes easier.
