Background technology
Biogas is a kind of renewable energy source, by the organism generation of fermenting in methane-generating pit.Temperature is one of key factor that affects biogas fermentation aerogenesis rate, when the methane-generating pit temperature more than 15 ℃ the time, biogas fermentation could carry out preferably, 35 ℃ is a peak of biogas fermentation aerogenesis.Temperature in the methane-generating pit changes with Seasonal occurrence.The northern area of China cold in winter is very long, and temperature, surface temperature are lower, and the methane tank gas production rate is low, can't satisfy peasant household's demand, causes the winter methane-generating pit to have a large amount of idle problems.Even be subjected to the impact of ground temperature summer, the temperature in the methane-generating pit is not high yet, and the factor of created gase of methane-generating pit is affected.Usually take measures methane-generating pit is heated for the temperature that improves methane-generating pit, the methane-generating pit volume is larger, and not only to heat the heat that needs more for whole methane-generating pit, the radiating surface of methane-generating pit is also larger simultaneously, and heat dissipation capacity is also many.If built methane-generating pit is carried out temperature raising and maintaining, also need again to excavate methane-generating pit and construct, difficulty increases.
Summary of the invention
The purpose of this utility model provides a kind of split type temperature-raising marsh pool, improves the temperature of biogas fermentation, improves the biogas fermentation condition, improves production rate of methane.
The utility model provides following technical scheme: comprise methane-generating pit and efficient methane reactor, it is characterized in that: the efficient methane inside reactor arranges interchanger, thermal insulation layer is established in the outside, and its charging and discharging pipe is connected with methane-generating pit, and escape pipe is connected with the escape pipe of methane-generating pit; Feed-pipe at the efficient methane reactor is assembled water pump, and the temperature sensor of temperature controller is set in the efficient methane reactor, and temperature controller connects water pump; Hot-water line and rising pipe are advanced in interchanger setting in the efficient methane reactor.
Positively effect of the present utility model: increase the efficient methane reactor at common methane-generating pit and heat, be convenient to common methane-generating pit is transformed, reduced the construction cost of temperature raising and maintaining.By taking to heat measure, guaranteed the leavening temperature in the efficient methane reactor, also improved the temperature in the methane-generating pit simultaneously, increased production rate of methane.Play stirring action by the water pump circulation, promoted biogas fermentation.
