Background technology
Along with the raising of human living standard, energy utilization is progressively moved towards to clean and Sustainable development.In recent years, in rural area, many peasant households have all set up domestic methane tank, and big-and-middle-sized methane-generating pit.As everyone knows, fermenting organic material is prepared biogas and is belonged to biofermentation technique, bacterium temperature influence in fermentation reaction for fermenting in the liquid of natural pond is larger, research shows, within the scope of 15 ~ 40 DEG C, along with the rising factor of created gase of temperature correspondingly increases, temperature often rises 10 DEG C, speed of reaction about increases by 2 ~ 3 times, and same fermentation raw material is equivalent to 15 DEG C of condition bottom fermentations gas production rate of 6 ~ 9 months for one month at the condition bottom fermentation of 35 DEG C.When biogas fermentation temperature is lower than 10 DEG C, microorganism enters dormancy, and gas production rate is few, and biogas then cannot normally use at all.In addition, the fluctuation of temperature is also very large on factor of created gase impact.Such as in ferment at constant temperature process, the temperature of 1h fluctuates up and down can not more than 2 ~ 3 DEG C, and gradient of temperature 5 DEG C in the short period of time, gas production rate will obviously decline, and even can stop aerogenesis when fluctuating excessive.Therefore, keep suitable stable biogas fermentation temperature, higher factor of created gase could be maintained.China's various places temperature condition differs greatly, and the temperature difference is also large throughout the year in various places, and old friends, to how to improve and control methane-generating pit temperature of reaction, suit measures to local conditions to research and develop and put into practice, are proposed and much heat temperature control technique.
It is as follows that current widely used several biogas fermentation heats temperature control technique: 1 electric heating film temperature raising and maintaining system electric heating film temperature raising and maintaining system uses the electric current principle of being generated heat by metallic conductor, be heat energy is methane-generating pit heating by electric energy conversion.The remarkable advantage of this technology be heat up evenly, the treatment time is short, energy conversion rate is high and be not subject to external environment (region and weather etc.) impact, solves methane-generating pit heating in the winter time and insulation problem to a certain extent.But many high-grade electric energy need be consumed due to electric heating system, its energy saving and social economy's property are not good.2 boiler water circulation methane-generating pit temperature-increasing system boiler water circulation heating methane tank know-whies discharge a large amount of heat energy for being burnt in the boiler by fuel and carry out heating cycle water, hot water is delivered in the interchanger be combined as a whole with methane-generating pit by circulation line, interchanger then by thermal energy transfer in hot water in the liquid material of biogas fermentation, realize the lifting of methane-generating pit temperature of reaction.3, solar water heater water cycle methane-generating pit temperature-increasing system, its heating system adopts solar water heater as main heater block, and by circulation line by the interchanger of delivery to methane-generating pit, interchanger is to liquid heat release in natural pond in methane-generating pit, improve and keep the temperature of methane-generating pit, thus improve the gas production rate of biogas.But because Solar use is comparatively large by weather effect, make it promote certain limitation.
Summary of the invention
For solving the problems referred to above that prior art exists, the purpose of this utility model provides a kind of influenced by ambient temperature little, and factor of created gase is high, the organic substance biogas fermentation device that production energy consumption is little.
For achieving the above object, the technical solution adopted in the utility model: this organic substance biogas fermentation device, there is anaerobic digester, it is characterized in that: the top of described anaerobic digester is covered with the transparent heat-insulation canopy of arch, is covered with transparent heat-insulation film at the opening part of anaerobic digester; The bottom of anaerobic digester is equipped with many row's biogas return lines, biogas return line is interval with multiple biogas spout, and described many row's biogas return lines connect biogas output tube by gathering tube; The inwall of anaerobic digestion pond liquid ullage is provided with hot water circulating pipeline, hot water circulating pipeline connects boiler by control valve, temperature sensor is located at below the liquid liquid level of anaerobic digestion pond, temperature sensor connection control device, and controller controls the folding of control valve; Described anaerobic digester is communicated with pretreatment pool by feed pipe, and pre-treatment pool side is provided with the machinery that feeds intake, and anaerobic digester is combined with natural pond liquid pump, and natural pond liquid pump is connected with pressure pan by pipeline, and the liquid outlet of pressure pan is communicated with pretreatment pool.
Described anaerobic digester is multiple being arranged side by side.
Described transparent heat-insulation canopy and transparent heat-insulation film are provided with air door.
Adopt the beneficial effect of technique scheme: this organic substance biogas fermentation device is covered with the transparent heat-insulation canopy of arch above anaerobic digester, transparent heat-insulation film is covered with at the opening part of anaerobic digester, sunlight is shining in anaerobic digester by transparent roof insulating and insulation film, make full use of sun power to heat anaerobic digester, roof insulating and insulation film have good insulation effect, in addition the organic substance heat that self produces when fermenting, thus maintain rational biogas fermentation temperature, affect little by ambient temperature, and then reach the object improving methane gas producing amount.Be equipped with many row's biogas return lines in the bottom of anaerobic digester, biogas return line be interval with multiple biogas spout, described many row's biogas return lines connect biogas output tube by gathering tube.Open the valve of gathering tube, biogas by gathering, biogas return line and biogas spout be back in anaerobic digester, natural pond liquid in digester circulates up and down under the drive of air-flow, make the natural pond liquid of bottom consistent with natural pond, top liquid temp, avoid that the temperature of natural pond, top liquid is too high causes fermenting bacteria to lose activity.The inwall of anaerobic digestion pond liquid ullage is provided with hot water circulating pipeline, hot water circulating pipeline connects boiler by control valve, overcast and rainy without the sun in winter, when in anaerobic digester, temperature does not reach organic substance high-efficiency fermenting active temperature, by boiler heat hot recirculated water, heat anaerobic digester, roof insulating and insulation film can double-layer heat insulations, can also fermentation gas normally and efficiently under the envrionment temperature that temperature is lower.When fermentation reaction temperature reaches design temperature, sensor temperature signals is passed to controller, and closing of controller adjusting control valve opening, prevents temperature too high.
