Description

Simple and easy sunlight methane-generating pit

Technical field

The utility model relates to a kind of body refuse treatment unit, particularly a kind of simple and easy sunlight methane-generating pit.

Background technology

Biogas is a kind of cleaning reproducibility energy, in recent years for improving China's vast farmers quality of life, the Chinese government widelys popularize biogas technology, but problems such as at present construction of marsh gas tank exists all generally that manufacture difficulty is big, the engineering time is long, technical requirements is high, cost of manufacture is high, poor stability, factor of created gase are low, it is difficult to cause methane-generating pit to promote.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of cost low, make simple, to make the pond time shorter, and can make full use of solar radiation and heat up and improve factor of created gase, the simple and easy sunlight methane-generating pit that generally promote in suitable rural area.The purpose of this utility model realizes by following technical proposals: the utility model is made up of fermentation vat, floating cover, airway, floating cover is for formulated by light material support and plastics film, floating cover floats on the fermented liquid of fermentation vat, light material support top is affixed by transom and airway one end, and the airway the other end fermented liquid in the pond by fermentation is connected on the biogas burner.

Described light material be bamboo and wood or porous plastics any.

Described transom be pipe thread or pipe clamp or rope any.

As required, can establish feed inlet and outlet in the bottom of simple and easy sunlight methane-generating pit fermentation vat one side, between the external input and output material of feed inlet and outlet, the height between input and output material equates with the height of fermentation vat, the growing and be wider than or equal the length of feed inlet and outlet and wide of top, with the obliquity of fermentation vat outside be the 20-70 degree.

The utility model does not need the sealing of fermentation vat top is increased degree of safety on the one hand, uses the floating cover of the plastics film that is difficult for gas leakage on the other hand, not only reduces cost, and is convenient to utilize sun power to improve the fermentation vat temperature, increases biogas output.From above-mentioned situation as can be known, the purpose of this utility model can realize.

Compared with prior art, the utlity model has following advantage:

1, simple in structure, make, use, safeguard easily.A general methane-generating pit only needs 2-5 worker promptly to can be made into, and only needs rural area instrument commonly used;

2, cost of manufacture is low, is easy in the rural area promote.Build peasant household's methane-generating pit of confession one a tame four-player, the about 200-400 of cost of manufacture unit;

3, aerogenesis is fast, and gas production rate is big.Owing to made full use of the effect of sunlight, sunlight shines directly on the floating cover, and temperature increase is fast, also at double growth of biogas output;

4, do not have the disease pond, can normally use yet even leak or go out under the fertile situation at fermentation vat;

5, safety performance is good, does not have potential safety hazard.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a configuration diagram of the present utility model;

Fig. 2 has configuration diagram between input and output material for the utility model.

Embodiment

Embodiment 1: as shown in Figure 1, the utility model comprises fermentation vat 1, floating cover 2, airway 3.Be chosen in preferably that effective pigsty or the cattle pen excrement water hole place of daylighting builds fermentation vat 1 outside the own room, fermentation vat 1 can be on the ground be built into brick or concrete or other materials, its long, high, wide can be according to the gas consumption size design, generally with long 2-5 rice, wide 1-3 rice, high 1-3 rice is advisable, and present embodiment is selected brick mix structure for use, length is 3 meters, wide 2 meters, high 2 meters rectangle, and fermentation vat also can be garden cylindricality, trilateral, trapezoidal certainly.Floating cover 2 makes one long 2.5 meters, wide 1.9 meters, high 1 meter rectangular support frame with timber or other light materials earlier, again plastics film is fixed on the rectangular support frame, fixed form can with nail, rope prick admittedly all can, it should be noted that should to make whole cover body (except that the bottom) sealing air tight.Certainly floating cover 2 also can be made into trapezoidal, and semicircle all can.Floating cover 2 floats on the fermented liquid of fermentation vat 1, airway 3 one ends are fixed on the upper bracket of floating cover 2 by pipe thread, conduit the other end pond 1 interior fermented liquid (natural pond liquid) by fermentation is directly connected on the burner (lamp), and airway 3 diameters are good with 0.02-0.05 rice.Present embodiment is selected 0.03 meter for use, in the use, as the needs input and output material, generally is after using biogas, only needs to float cover 2 and removes, and can carry out input and output material.

Embodiment 2: as shown in Figure 1, comprise fermentation vat 1, floating cover 2, airway 3.Effective pigsty or the cattle pen excrement water hole place of daylighting that preferably is chosen in outside the own room builds fermentation vat 1, fermentation vat 1 can underground dig one long be 4 meters, wide 1 meter, high 3 meters rectangle hole, and with floating four sides wall of concrete and bottom.Floating cover 2 makes one long 3.5 meters, wide 0.9 meter, high 2 meters rectangular support frame with bamboo wood or other materials earlier, plastics film is fixed on the rectangular support frame again, floats over after making on the fermented liquid of fermentation vat 1.On floating cover 2 upper bracket, the other end pond 1 interior fermented liquid by fermentation is directly connected on the use object airway 3 one ends by lanyard, and airway 3 diameters are 0.02 meter.At any time can input and output material, only need during input and output material will float cover 2 on one side to moving, just can input and output material in the gap of removing.
