Description
Technical field
What the present invention relates to is methane-generating pit, especially refers to a kind of float cover type biogas generating pit.
?
Background technology
Biogas is through the development of many decades, and people are already from requiring to be transferred to higher level to its initial low order function.Especially society, to improving the attention of energy dilemma and Rural Environmental Problem, is popularized biogas and is just more seemed important.But traditional methane tank cost is high, floor space is large, the complicated operation of discharging and charging, and operation and maintenance is loaded down with trivial details and also exist the situation of certain potential safety hazard still to exist.For example, when the filler in the fermentation vat of traditional methane tank ferments, will certainly touch storage air-float hood, not only unhygienic but also accelerated the corrosion of storage air-float hood, reduce work-ing life, increase the weight of user's economical load, increase popularization difficulty.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of float cover type biogas generating pit, and this biomass pool structure is simple, cost is lower, easy for installation, regular job is convenient, and stopping composition in fermentation vat contact with storage air-float hood, health, prolongation in work-ing life;
For solving the problems of the technologies described above, float cover type biogas generating pit provided by the invention, fermentation vat and storage air-float hood are comprised, it is characterized in that: the sidewall of described fermentation vat is double layer hollow structure, storing wall is connected with the sealed bottom of water storage wall, hollow space forms hopper, described storage air-float hood is made up of upper cover and cover wall, cover wall is positioned at hopper, the top of upper cover is provided with gas port, the lower rim of upper cover is provided with flange A, and the upper limb of cover wall is provided with flange B, between flange A and flange B, is bolted to connection and seals;
In order to ensure the stopping property of storage air-float hood, prevent that the biogas in fermentation vat from leaking outside, between described flange A and flange B, be provided with seal washer;
Storage air-float hood can float gradually because of the increase of the biogas amount in fermentation vat, and the hypervolia in hopper can cause storing air-float hood lifting height and fall compared with large crank, is therefore provided with overflow port in the upper end of the water storage wall of described fermentation vat;
In order to increase the gas-storing capacity of methane-generating pit, the upper surface of the flange A of described storage air-float hood is evenly provided with three counterweight bolts, equiponderant weight can be tied respectively on three counterweight bolts;
In order to be convenient for people to observe at any time and to understand the waste material fermentation situation in fermentation vat, the zygomorphy of the upper cover of described storage air-float hood is provided with view port;
In order to facilitate discharging and to extract at any time organic fertilizer, the bottom of described fermentation vat is provided with discharge nozzle;
Described discharge nozzle is provided with valve;
The invention has the advantages that: this biomass pool structure is simple, cost is lower, easy for installation, floor space is little, be placed in and on ground, get final product fermentation and biogas production, charging and discharging are all very convenient, be convenient to clean fermentation vat simultaneously, and the storage air-float hood of this float cover type biogas generating pit does not contact with the waste material in fermentation vat, solve that storage air-float hood is easily corroded and an antihygienic difficult problem, extend the work-ing life of methane-generating pit.

Brief description of the drawings
Below in conjunction with accompanying drawing, the present invention will be further described;
Fig. 1 is the one-piece construction schematic diagram of described float cover type biogas generating pit;
Fig. 2 is the part sectioned view of described float cover type biogas generating pit;
In figure: 1 fermentation vat, 2 hoppers, 3 upper covers, 4 storing walls, 5 water storage walls, 6 cover walls, 701 flange A, 702 flange B, 8 bolts, 9 overflow ports, 10 seal washers, 11 counterweight bolts, 12 view ports, 13 discharge nozzles, 14 valves, 15 gas ports.
