Description

Split type temperature-raising marsh pool
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, by the organism generation of in methane-generating pit, fermenting.Temperature is one of key factor that influences the biogas fermentation factor of created gase, 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 is with changing season.North 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 receive the influence 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 bigger, makes that not only to heat the heat that needs more for whole methane-generating pit, and the radiating surface of methane-generating pit is also bigger simultaneously, and heat dissipation capacity is also many.If the methane-generating pit that has built up is carried out temperature raising and maintaining, also need excavate methane-generating pit again and construct, difficulty increases.
Summary of the invention
The purpose of this invention is to provide a kind of split type temperature-raising marsh pool, improve the temperature of biogas fermentation, improve the biogas fermentation condition, improve the methane gas producing rate.
The present invention provides following technical scheme: comprise methane-generating pit and efficient methane reactor drum; It is characterized in that: the efficient methane inside reactor is provided with 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; On the feed-pipe of efficient methane reactor drum, assemble water pump, the TP of temperature controller is set in the efficient methane reactor drum, temperature controller connects water pump; Hot-water line and rising pipe are advanced in interchanger setting in the efficient methane reactor drum.
Positively effect of the present invention: on common methane-generating pit, increase the efficient methane reactor drum and heat, be convenient to common methane-generating pit is transformed, reduced the construction cost of temperature raising and maintaining.Through taking the measure of heating, guaranteed the leavening temperature in the efficient methane reactor drum, also improved the temperature in the methane-generating pit simultaneously, increased the methane gas producing rate.Play stirring action through the water pump circulation, promoted biogas fermentation.

Embodiment
Shown in accompanying drawing 1-3, the present invention is made up of major portions such as methane-generating pit 1, efficient methane reactor drum 7, temperature controller 5, water pumps 4.Efficient methane reactor drum 7 set inside interchanger 10; Efficient methane reactor drum 7 connects charging and discharging pipe 3,9 and escape pipe 8; The charging and discharging pipe 3,9 of efficient methane reactor drum 7 connects methane-generating pit 1; The opening for feed of feed-pipe 3 is positioned at the methane-generating pit middle part, for preventing to stop up, the strainer 2 that filtering net surrounds is housed before the opening for feed; On feed-pipe 3, connect water pump 4; The escape pipe 8-1 of efficient methane reactor drum 7 connects the escape pipe 8 of methane-generating pit; The TP 6 of temperature controller 5 can adopt the thermal resistance type transmitter, is arranged in the efficient methane reactor drum 7, is used to control 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 bigger, 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 drum is connected with the water inlet pipe and water outlet pipe of hot water.
The efficient methane reactor drum 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, like paraffin, Na 2SO 410H 2O etc. use after the encapsulation.Adding lagging material 12 in efficient methane reactor drum outside is incubated.Described efficient methane reactor drum 7 can adopt the anaerobic reactor of patterns such as fluidized-bed or up-flow anaerobic sludge blanket.The heating of low-grade energies such as the hot water sun power capable of using in the said interchanger, biomass energy, waste heat obtains.
Principle of work: the natural pond liquid with water pump 4 extracts in the methane-generating pit 1 is sent in the efficient methane reactor drum 7; Hot water inflow heat exchanger 10 backs heat efficient methane reactor drum 7; With the temperature in the temperature controller 5 control efficient methane reactor drums 7 in optimal temperature; Temperature controller has the bound function, can open water pump when being higher than design temperature, switches off the pump when being lower than design temperature.Temperature controller 5 control water pumps 4 are opened when temperature raises; Low temperature natural pond liquid pump in the methane-generating pit is gone in the reactor drum, and the high temperature natural pond liquid in the efficient methane reactor drum 7 is discharged in the methane-generating pit 1, keeps the temperature in the efficient methane reactor drum 7; Temperature in the methane-generating pit 1 is improved; So continuous circulation when guaranteeing the efficient methane reactor temperature, can progressively improve the temperature in the methane-generating pit 1.Water pump quits work when arriving controlled temperature, keeps leavening temperature in the efficient methane reactor drum 7.
