Description
Technical field
The utility model relates to a kind of anaerobic ferment devices, the anaerobic ferment devices that the direct biogas of particularly a kind of stalk utilizes, and it is adapted at a large amount of stalks and the few area use of animal excrement.
Background technology
Along with the gradually intensification of people to energy dilemma understanding, biogas is paid attention to by people day by day as a kind of renewable energy source, especially uses by numerous rural subscribers and is favored.Under the vigorously supporting of country, by 2010, China rural area reached 4,000 ten thousand families with the scale of biogas, had brought into play enormous function to solving China life in the countryside energy problem.But, at present because China rural area is in the industry restructuring stage, tradition is based on the family-raise atrophy of peasant household, the simple feces of livestock and poultry that relies on is done unrealistic that the biogas fermentation raw material has become, and have following problem: one, some local methane-generating pit depleted phenomenons happen occasionally, and the methane-generating pit service efficiency is lower; Two, little, the volume of the density of stalk has flowability greatly and not, can't continuously feeding, discharging and carry out the successive anaerobically fermenting, and therefore, the existing feces of livestock and poultry that is used for is produced the biogas production that the reactor of biogas all can't directly be effective to stalk; Three, stalk is the more common waste in rural area, and the annual at present amount that produces stalk of China is 4.9～600,000,000 tons, because the development of rural society, stalk is progressively lost as the function of fuel wood and feed, becomes one of principal element of environmental pollution.At these problems, seeking novel fermentation unit is the key that addresses these problems.
The utility model content
Technical problem to be solved in the utility model provides the anaerobic ferment devices that the direct biogas of a kind of stalk utilizes, the present situation that it is not enough at China's rural area household biogas fermentation raw material and the stalk waste is serious, in conjunction with the physical property of stalk, the rural area household biogas is efficiently utilized and the stalk resource utilization.
For solveing the technical problem, the utility model provides a kind of stalk anaerobic ferment devices that direct biogas utilizes, it comprises loading bay, opening for feed, the whipping appts transmission apparatus, separation net, airway, whipping appts, leak car, air storage chamber, discharge port, proving room, anti-drip valve, it is characterized in that, opening for feed is positioned at the top of loading bay, two anti-drip valve respectively above the opening for feed and discharge port above, the whipping appts transmission apparatus is connected with whipping appts, whipping appts is in proving room, air storage chamber is above whipping appts, separation net is between air storage chamber and whipping appts, and airway is fixed on the air storage chamber, leaks the parking stall in the below of discharge port.
Preferably, the below of described whipping appts is provided with at the bottom of the methane-generating pit pond, and the cross-sectional shape at the bottom of the methane-generating pit pond is a ramped shaped.
Positive progressive effect of the present utility model is: the utility model not only can reach efficient fermentation and make things convenient for the effect of discharging, and the operation of its safe ready has solved fully because of the difficult personnel safety problem of bringing of discharging.
Description of drawings
Fig. 1 is the structural representation of the anaerobic ferment devices of the direct biogas utilization of the utility model stalk.
Embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 1, the anaerobic ferment devices of the direct biogas utilization of the utility model stalk comprises loading bay 1, opening for feed 2, whipping appts transmission apparatus 3, separation net 4, airway 5, whipping appts 6, leak car 7, air storage chamber 8, discharge port 9, proving room 10, anti-drip valve 11, opening for feed 2 is positioned at the top of loading bay 1, two anti-drip valve 11 respectively above the opening for feed 2 and discharge port 9 above, whipping appts transmission apparatus 3 is connected with whipping appts 6, whipping appts 6 is in proving room 10, air storage chamber 8 is above whipping appts 6, separation net 4 is between air storage chamber 8 and whipping appts 6, airway 5 is fixed on the air storage chamber 8, leak car 7 and be positioned at the below of discharge port 9, the below of whipping appts 6 is provided with at the bottom of the methane-generating pit pond 12.
The principle of work of the anaerobic ferment devices that the direct biogas of the utility model stalk utilizes is as follows: in the beginning of a fermentation period, at first open airway 5, valve is with air emptying in the methane-generating pit (remaining basically stable the inside and outside pressure of methane-generating pit), and startup whipping appts 6 carries out the quick stirring of certain hour.Again the pretreated fermentation raw material (stalk) for the treatment of is rendered to opening for feed 2 from loading bay 1, the natural pond liquid that the material machine is extracted into is taken out in utilization to be washed, make it enter proving room 10 fully, meanwhile carry out certain stirring (making fermentation raw material enter the fermentation position), fermentation raw material and fermented liquid (zymophyte) are mixed.When the natural pond slag of 7 li in the leakage car at discharge port 9 places reaches a certain amount of, can hang out Lou that car 7 carries out discharging, after input and output material finishes,, and anti-drip valve 11 places separately be filled water, further reach the effect of sealing opening for feed 2 and discharge port 9 sealings.Wherein, whipping appts transmission apparatus 3 utilizes the cam mechanism principle, and fermentation materials is played stirring action.The biogas that anaerobically fermenting produces is stored in the air storage chamber 8.
In this fermentation period, carry out suitable stirring by the regular hour, make fermentation raw material and fermented liquid remain at mixed uniformly state, and the natural pond slag that will ferment is delivered in the leakage car 7 at discharge port 9 places.In a fermentation period, carry out repeatedly periodic stirring and discharging, to reach the purpose of efficient fermentation and continuous discharging.12 cross-sectional shape is a ramped shaped at the bottom of the methane-generating pit pond, provides convenience for discharging when can increase the fermentation area like this.The design of separation net 4 has solved the problem of fermented stalk come-up, makes fermentation raw material make full use of efficient utilization with village's household biogas, has improved gas producing efficiency.
Need to prove, the utility model not only can reach efficient fermentation and make things convenient for the effect of discharging, and the operation of its safe ready has solved fully because of the difficult personnel safety problem of bringing (build the pond and reach design requirements, do not need the people to go into the pond and operate) of discharging.
Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
