Abstract

The invention relates to a reversed barrel type methane fermentation device which is composed of a bracket, a spring, a screw, a gas-pressure meter, a valve and the like. The reversed barrel type methane fermentation device is a reversed barrel-shaped device which is reversed in liquid manure to serve as a methane fermentation tank, and is characterized in that a convenient disassembling and assembling process can be realized, methane can be cyclically collected and the fermentation tank can be mechanically cleaned. The device can realize industrial manufacturing, a single device for home use can be quickly installed on an original manure pit, and multiple devices can be installed for the breeding industry; and the produced methane can be pressurized and then used for power generation. The thrust of the gas pushes the barrel-shaped device upwards, and the spring presses the barrel-shaped device downwards, so that the methane can move into an output pipeline and can be used after the valve is opened; and the use condition of the methane can be known through the gas-pressure meter. When the methane is reduced, the spring can press the barrel opening into the manure at the bottom of the pit; and when a methane output pipe is closed, the methane in the barrel-shaped device pushes upwards, thus realizing the storage and output of the methane. When the methane is not used, a gas use valve can be closed; and when an emergency valve is opened, potential safety hazard can be eliminated.

Description

Back-off bucket formula biogas fermentation device

Technical field

The present invention relates to a kind of back-off bucket formula biogas fermentation device, especially can easy disassembly, the equipment of circulating collection biogas and cleaning fermentation vat.

Background technology

The aquaculture such as raise pigs all facing to a common blowdown difficult problem.Ight soil is dealt with improperly not only can contaminated land, makes change manure pit, good farmland, brings disaster to river and underground water; But also can polluted air, near hundreds of square metres even several thousand squares foul smell brings disaster to.Chlorinated lime deodorizing at all, makes pollution grows worse on the contrary.But so-called foul smell is biogas in fact, formal name used at school methane, is the free of contamination energy.The ight soil that takes biogas is the harmless fertilizer of odorless.

The methane-generating pit principle using is at present a feed-pipe charging, and a middle very large fermenting tank for fermentation, has a discharge hole for discharge on the opposite of feed-pipe.When fermentation vat produces when biogas, just ight soil hydraulic pressure to feed-pipe and discharge port, the ight soil amount of extrusion and biogas amount equate, the biogas that can discharge is very limited; It also has following shortcoming:

The first, building time is long, and expense is high.Methane-generating pit can not fast construction, can not large-scale industrializedly manufacture again;

The second, because fermentation vat is very dark, the easy discharging difficulty of charging, hidden place is built in the manure pit of mountain area farmers' in more, can not original place Jian Chi, need manually ight soil is sent into methane-generating pit;

The 3rd, because methane-generating pit can not be cleared up with mechanised equipment, transport waste material, so when waste from stacking is to a certain extent time, methane-generating pit just can not re-use.

In sum, current methane-generating pit can not provide the stable energy, can not recycle for a long time again.This also makes methane-generating pit build repeatly and abandon repeatly, and ground and water source are formed to secondary pollution.

Summary of the invention

Back-off bucket formula biogas fermentation device, by support, spring, screw, the compositions such as weather gage, valve, are buckled in the fermentation vat as biogas in the liquid manure in manure pit using the barrel-shaped equipment of a back-off.In the time having biogas to produce, the thrust of gas upwards pushes away barrel-shaped equipment, and the spring on barrel-shaped equipment is depressed into output channel by biogas downwards, opens valve, can use.In the time that biogas reduces, at the bottom of the spring on barrel-shaped equipment can be depressed into manure pit by bucket; When for a long time without biogas, can close with air valve, open standby valve, can eliminate safe hidden trouble.Can understand at any time the service condition of biogas from weather gage.

When the present invention is applied in family, without changing family expenses manure pit, the back-off bucket formula biogas fermentation device of suitable dimension only need be installed in manure pit, can use biogas; And the present invention is while being applied in large-scale plant, channel type need be built up in manure pit, need not be too dark, but width must hold mini-excavator and agricultural vehicle operation; On canal, assemble multiple back-off bucket formula biogas fermentation devices, just can collect a large amount of biogas and do combustion gas or the use of generating equal energy source.In the time that channel is filled up by ight soil, take back-off bucket formula biogas fermentation device away, dig out the fertilizer that there is no biogas (foul smell) in channel with excavator, agricultural vehicle is sent to ight soil to do Fertilizer application again.So both can guarantee the stable output of biogas, can make again becomes the harmless organic fertilizer of odorless, energy-conserving and environment-protective after manure fermentation.

Main purpose of the present invention is, a kind of biogas that ight soil produces that solves is provided, and is converted into the equipment of the safe available energy.In addition, the mash-back of back-off bucket formula biogas fermentation device is injection moulding, and remaining part etc. can factory be produced in batches, and therefore cost is not high.
