Biogas mainly is to be decomposed by human and animal excreta or plant fermentation to produce, and belongs to reproducible clear energy sources, is widely used in the rural area.General methane-generating pit all relies on the temperature of physical environment to impel the fermentation of ight soil or green grass, when temperature is higher, can normally use, in case and temperature when being lower than the leavening temperature of ight soil, methane-generating pit is with stop supplies biogas.For example on the grassland in the north of China, livestock industry is very flourishing, and produce a large amount of ight soil every day, can provide methane-generating pit competent raw material.But because the northern winter temperature of China is very low, methane-generating pit can't run well, and has caused the significant wastage of resource.
In addition, under the constant situation of other condition, the height of temperature has very big influence to the factor of created gase of methane-generating pit.For example, (8 ℃～25 ℃) at normal temperatures, the factor of created gase of pig manure generally is 0.25～0.30, the factor of created gase of cow dung generally is 0.20～0.25, the factor of created gase of green grass generally is 0.20～0.25, and in the time of 35 ℃, the factor of created gase of pig manure can reach 0.45, the factor of created gase of cow dung can reach 0.30, and the factor of created gase of green grass can reach 0.44.Illustrate, improve the temperature of methane-generating pit, can accelerate the decomposing and fermenting process of ight soil and green grass, improve the utilising efficiency of ight soil and green grass.
Summary of the invention
At above-mentioned situation, the purpose of this utility model is: a kind of sun power temperature control type methane-generating pit is provided, methane-generating pit can be used in the winter of cold, and improve the factor of created gase of methane-generating pit.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of sun power temperature control type methane-generating pit, it is characterized in that: it comprises solar water heater, water pump, extra power, the water pump control end, temperature sensor and water back, described solar water heater is connected with a water inlet pipe and an outlet conduit, described outlet conduit is connected to described water pump, described water pump again be arranged on methane-generating pit in an end of water back communicate, the other end of described water back then communicates with the water inlet pipe of solar water heater, described water pump is provided with the water pump control end, described water pump control end is monitored temperature in the methane-generating pit at any time by a temperature sensor, and described water pump also is electrically connected with an extra power.
Wherein: described extra power is a solar panel.
Wherein: described extra power is an aerogenerator.
Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be:
1, methane-generating pit can be used in the winter of cold, it is little influenced by geographical environment or seasonal temperature;
2, improve the methane-generating pit temperature, thereby improve factor of created gase;
3, total system is all used renewable energy source, and is energy-saving and cost-reducing, non-environmental-pollution.
Description of drawings
Fig. 1 is the structural representation of the utility model first embodiment;
Fig. 2 is the structural representation of the utility model second embodiment;
Embodiment
The utility model comprises: solar water heater 1, water pump 2, solar panel 3, water pump control end 4, temperature sensor 5 and water back 6.As shown in Figure 1, described solar water heater 1 receives irradiation of sunlight and makes its inner water storage heating, described solar water heater 1 also is connected with a water inlet pipe 7 and an outlet conduit 8, described outlet conduit 8 is connected to described water pump 2, described water pump 2 communicates with an end of the water back 6 that is arranged on methane-generating pit bottom and sidewall again, and the other end of described water back 6 then communicates with the water inlet pipe 7 of solar water heater 1.Described solar panel 3 is arranged on the methane-generating pit outside and is electrically connected with described water pump 2, to provide water pump 2 electric power, and described water pump 2 is provided with water pump control end 4, described water pump control end 4 is monitored temperature in the methane-generating pit at any time by a temperature sensor 5, when temperature in the methane-generating pit is lower than a certain preset temperature (as 20 ℃), water pump control end 4 promptly sends a signal to water pump 2 and makes water pump 2 runnings, and the hot water in the solar water heater 1 will be got back to constantly circulation in the solar water heater 1 after will flowing through water back 6, thereby make the interior temperature of methane-generating pit owing to heat exchange improves constantly.When temperature in the methane-generating pit was higher than another preset temperature (as 40 ℃), water pump control end 4 promptly sends a signal to water pump 2 shut down water pump 2.
Above-described preset temperature does not specifically limit in addition, can corresponding adjustment with the difference of local natural environmental condition and methane-generating pit filler, and in the hope of reaching suitable aerogenesis effect.
Thus, even in the winter of cold, the temperature in the methane-generating pit also can remain on a higher position, makes the decomposing and fermenting of ight soil and green grass continue to carry out, thereby makes methane-generating pit can not be subjected to the influence of temperature to continue to use.Because solar water heater 1 of the present utility model and solar panel 3 all are to use sun power, can any negative impact not arranged to environment, highly meet environmental protection requirement, are worthy to be popularized.
In the utility model, do not limit the shape and the riding position of water back 6, can use and the general similar heating piece 61 of floor heating radiator, also can use snake pipe 62, can also be the heating piece 61 and the snake pipe 62 of contacting mutually, the rate of heating of water liquid can be improved in the bottom that water back 6 is placed on the bottom of methane-generating pit and sidewall.
