Description
Technical field
The present invention relates to a kind of biogas generating device, particularly a kind of split type temperature-raising marsh pool.
Background technology
Biogas is a kind of renewable energy source, the generation of being fermented in methane-generating pit by organism.Temperature is one of key factor affecting biogas fermentation aerogenesis rate, and when methane-generating pit temperature is when more than 15 ℃, biogas fermentation could carry out preferably, and 35 ℃ is a peak of biogas fermentation aerogenesis.Temperature in methane-generating pit is with changing season.The northern area of China cold in winter is very long, and temperature, surface temperature are lower, and methane tank gas production rate is low, cannot meet peasant household's demand, causes winter methane-generating pit to have a large amount of idle problems.Even if in summer, be subject to the impact of ground temperature, the temperature in methane-generating pit is not high yet, and the factor of created gase of methane-generating pit is affected.For improving the temperature of methane-generating pit, conventionally take measures methane-generating pit to heat, methane-generating pit volume is larger, not only makes that to heat the heat needing more for whole methane-generating pit, and 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 to temperature raising and maintaining, also need again to excavate methane-generating pit and construct, difficulty increases.
Summary of the invention
The object of this invention is to provide a kind of split type temperature-raising marsh pool, improve the temperature of biogas fermentation, improve biogas fermentation condition, improve production rate of methane.
The invention provides following technical scheme: comprise methane-generating pit and efficient methane reactor, it is characterized in that: efficient methane inside reactor arranges interchanger, thermal insulation layer is established in 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; On the feed-pipe of efficient methane reactor, assemble water pump, the temperature sensor of temperature controller is set in efficient methane reactor, temperature controller connects water pump; Interchanger in efficient methane reactor arranges into hot-water line and rising pipe.
Positively effect of the present invention: increase efficient methane reactor and heat on common methane-generating pit, be convenient to common methane-generating pit to transform, reduced the construction cost of temperature raising and maintaining.By taking to heat measure, guaranteed the leavening temperature in efficient methane reactor, also improved the temperature in methane-generating pit simultaneously, increased production rate of methane.By water pump, circulate and played stirring action, promoted biogas fermentation.

Embodiment
As shown in accompanying drawing 1-3, the present invention is comprised of major portions such as methane-generating pit 1, efficient methane reactor 7, temperature controller 5, water pumps 4.Efficient methane reactor 7 inside arrange interchanger 10; Efficient methane reactor 7 connects charging and discharging pipe 3,9 and escape pipe 8, the charging and discharging pipe 3,9 of efficient methane reactor 7 connects methane-generating pit 1, the opening for feed of feed-pipe 3 is positioned at methane-generating pit middle part, for preventing stopping up, the strainer 2 that filtering net surrounds is housed before opening for feed; On feed-pipe 3, connect water pump 4; The escape pipe 8-1 of efficient methane reactor 7 connects the escape pipe 8 of methane-generating pit; The temperature sensor 6 of temperature controller 5 can adopt thermal resistance type sensor, is arranged in efficient methane reactor 7, for controlling the running of water pump 4; If water pump 4 power are less, temperature controller 5 can directly be connected with water pump 4; If water pump 4 power are larger, can on temperature controller 5, increase rly. and be connected with water pump 4, as shown in Figure 3.The interchanger 10 of efficient methane reactor is connected with the water inlet pipe and water outlet pipe of hot water.
Efficient methane reactor can add heat-storing material layer 11 and carry out accumulation of heat, and to improve the stability of leavening temperature, the heat-storing material of heat-storing material layer 11 can adopt phase change heat storage material, as paraffin, Na

2o etc., are used after encapsulation.In efficient methane reactor outside, adding lagging material 12 is incubated.Described efficient methane reactor 7 can adopt the anaerobic reactor of the patterns such as fluidized-bed or up-flow anaerobic sludge blanket.Hot water in described interchanger can utilize the low-grade energy heating such as sun power, biomass energy, waste heat to obtain.
Principle of work: send in efficient methane reactor 7 with the natural pond liquid that water pump 4 extracts in methane-generating pit 1, hot water inflow heat exchanger 10 is rear to be heated efficient methane reactor 7, with temperature controller 5, control temperature in efficient methane reactors 7 in optimal temperature, temperature controller has bound function, during higher than design temperature, can open water pump, during lower than design temperature, switch off the pump.When temperature raises, temperature controller 5 is controlled water pump 4 unlatchings, low temperature natural pond liquid pump in methane-generating pit is entered in reactor, high temperature natural pond liquid in efficient methane reactor 7 is discharged in methane-generating pit 1, maintain the temperature in efficient methane reactor 7, make the temperature in methane-generating pit 1 improve simultaneously, so continuous circulation, when guaranteeing efficient methane reactor temperature, can progressively improve the temperature in methane-generating pit 1.When arriving control temperature, water pump quits work, and in efficient methane reactor 7, maintains leavening temperature.
