Abstract
The utility model discloses a gas collecting and storing device of a biogas pool. The biogas pool comprises a fermentation pool, wherein, a soft cover is clasped on the upper part of the fermentation pool, the soft cover and the fermentation pool form a gas collecting and storing chamber, the soft cover and the wall of the fermentation are connected with each other in a gas sealing manner; a fixed cover is arranged on the outer cover of the soft cover. Compared with the prior technology, the utility model has the advantages that convenient construction, low cost, high strength, good wide tightness, volume changed according to biogas amount, and suitability for various biogas pools.
Description
Technical field
The utility model belongs to the biogas utilisation technology, is specifically related to a kind of methane-generating pit gas collection gas storage device.
Background technology
Biogas is the effective utilizations to biomass energy as a kind of novel renewable energy resources, and people are to the certain knowledge experience of utilization accumulation of biogas.Mostly common methane-generating pit is hydraulic type biomass pool now, and this methane-generating pit is had relatively high expectations to the intensity and the wide stopping property of pond vault, and it is big to execute the formula difficulty, the expense height.The constancy of volume of this methane-generating pit, methane-generating pit in use air storage space and fermenting space conflict mutually, and solution is to adopt gas-holder the biogas that produces in the methane-generating pit is taken away, but the investment of gas-holder is excessive, has limited and has promoted the use of.
Summary of the invention
Have above-mentioned deficiency for overcoming prior art, the purpose of this utility model is to provide a kind of intensity height, wide good leak tightness, and volume can be according to the biogas quantitative changeization, easy construction, the methane-generating pit gas collection gas storage device that cost is low.
For achieving the above object, the technical solution adopted in the utility model: this methane-generating pit gas collection gas storage device has fermentation vat, wherein: fastening has the software cover on the top of fermentation vat, software cover and fermentation vat form the gas collection gas dome, the software cover is connected for the hermetic seal structure with the fermentation vat pool wall, and the outer cover of software cover is provided with fixed cover.
Described gas collection gas dome and space outerpace are provided with gas exhaust duct, are provided with relief valve in gas exhaust duct; The gas collection gas dome also is provided with escape pipe, is provided with negative pressure control valve in the escape pipe, and the outlet of escape pipe is connected with the inlet mouth of air pump.
The top that described hermetic seal structure is the fermentation vat pool wall is provided with annular water tank along pool wall, and the opening of software cover is fastened in the annular water tank, is provided with the water of submergence software cover opening in annular water tank.
Adopt the beneficial effect of technique scheme: methane-generating pit gas collection gas storage device fastens on the top of fermentation vat pool wall the software cover, the software cover has constituted the pond vault of fermentation vat, software cover and the interior gas collection gas dome that forms of fermentation pool wall, the software cover is connected for the hermetic seal structure with the fermentation vat pool wall, how many software covers can opening or bounces back according to gas production rate in the fermentation vat, be that methane-generating pit gas collection gas dome volume can be according to the biogas quantitative changeization, make the pressure in the gas collection gas dome of methane-generating pit all the time can be not too high, in use air storage space and fermenting space conflict mutually to have solved methane-generating pit, the software cover is that flexible materials is made, the level of safety height.The outer cover of software cover is provided with fixed cover, limits the activity space of software cover, and wearing and tearing avoided by protection software cover and exposure in sunshine is aging, prevents that effectively the software cover from breaking.Relief valve after the air storage maximum under pressure automatically discharging carry out release, utilize air pump that biogas in the software cover is extracted during with gas and use, the biogas back cut-out aspirating pipeline automatically under the effect of negative pressure control valve of finding time.Compared with prior art, have easy construction, cost is low, the intensity height, and wide good leak tightness, volume can adapt to various types of methane-generating pits and use according to the biogas quantitative changeization.
Description of drawings
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
Fig. 1 is the structural representation of methane-generating pit gas collection gas storage device.
Embodiment
Methane-generating pit gas collection gas storage device as shown in Figure 1, has fermentation vat 1, the top of fermentation vat pool wall is provided with annular water tank 3 along pool wall, the opening of software cover 4 is fastened in the annular water tank 3, in annular water tank, be full of water, the opening of submergence software cover is connected for the hermetic seal structure with the fermentation vat pool wall thereby constitute the software cover.Form gas collection gas dome 6 in software cover and the fermentation pool wall, the software cover is that flexible materials is made, and how many software covers can according to the opening or bounce back of gas production rate in the fermentation vat, and methane-generating pit gas collection gas dome volume can change according to the biogas quantitative changeization.The outer cover of software cover 4 is provided with fixed cover 5, with the activity space of qualification software cover, and prevents that the software cover from breaking.Gas collection gas dome 6 is provided with gas exhaust duct with space outerpace, is provided with relief valve 2 in gas exhaust duct, and gas collection gas dome 6 also is provided with escape pipe 7, is provided with negative pressure control valve 8 in the escape pipe, and the outlet of escape pipe is connected with the inlet mouth of air pump.
