Abstract
The utility model discloses a temperature compensating type methane -generating pit. It by between feed inlet, fermentation vat, water pressure, sealed lid, heating coil, solar energy pipeline, solar energy collection system, electric heating system, control box, temperature sensor, valve etc. Constitute characterized by jointly: utilize temperature sensor in to the methane -generating pit temperature monitor, control heating system and circulation system, when the methane -generating pit temperature is lower, open the ball valve, solar water -heating conducts heat through the difference in temperature with the former feed liquid of fermentation in spiral heating coil and carries out heat exchange, the solar water -heating after the temperature reduces flows back to the storage water tank. When the moon, rain, snow weather sunshine amount are not enough, still can run well in succession for guaranteeing this system, open the electric heater among the heat storage tank this moment, the temperature reaches auto -power -off after the setting value. This solar energy methane -generating pit passes through the solar water -heating circulation and the electricity heating technique improves methane -generating pit factor of created gase in winter, reduces the methane -generating pit fluctuation range of air demand throughout the year, has improved the fermented factor of created gase of marsh gas.
Description
Technical field
The utility model-a kind of temperature compensating type methane-generating pit belongs to sun power and biomass energy utilization technologies field.Be mainly used in cold district methane-generating pit low temperature fermentation.
Background technology
Temperature is a key factor of methane-generating pit fermentation, in China cold district, methane-generating pit mostly is normal temperature fermentation, especially in the winter time temperature focus is that most methane-generating pit normally cannot use the even inactive phenomenon that bursting by freezing methane-generating pit even occurs, cause the waste of resource, also reduce the enthusiasm that peasant household uses and builds methane-generating pit simultaneously.For eliminating envrionment temperature to the impact of methane-generating pit, improving the factor of created gase of methane-generating pit, must heat in methane-generating pit.Heat about methane-generating pit heating, be incubated a lot of scheme, but be scarcely suitable for extremely frigid zones.Although it is feasible to utilize biogas boiler to heat, its self consumes the normal use of gas meeting extreme influence biogas user; Coal firing boiler is utilized to heat running cost higher, and heat is wayward, existing solar heating methane-generating pit method is more and more subject to concern and the attention of people, solar heating method, namely utilizing solar thermal collection system to complete collection and the transmission of heat energy, is that carrier carries out thermal exchange by heating coil and natural pond liquid with solar water, environmental protection, simple to operate, automatic operating can be realized, but the impact being subject to day situation can only carry out energy storage, heating having the daytime at sunshine.For solving this intermittence and the instability problem of sun power, the present invention proposes photovoltaic electrically heated and mates with electrically heated, when illumination is weak, can electricity consumption heat temporarily, the setting of electrical auxiliary heater achieves the mutual supplement with each other's advantages of sun power and biomass energy better, efficiently solve winter domestic methane tank cannot normally continuous high-efficient use bottleneck problem, reach good economic benefit and environmental benefit.
Summary of the invention
The technical problem that the utility model solves is: in China cold district, solar thermal collection system and Electric heating is utilized to heat to methane-generating pit, improve the leavening temperature of biogas in marsh gas fermentation pool, and improve the fermentation gas rate of biogas, thus increase economic efficiency.
The utility model solves the technical scheme that its technical problem adopts: a kind of temperature compensating type methane-generating pit, it is made up of jointly opening for feed, fermentation vat, water pressure house, sealing cover, heating coil, solar pipe, solar thermal collection system, electric heating system, controlling box, temperature sensor, valve etc., it is characterized in that: described heating coil is installed on fermentation vat bottom part down and inwall surrounding; Heating coil is communicated with solar thermal collection system by two solar pipes.Temperature sensor is utilized to monitor temperature in methane-generating pit, heating system and the recycle system are controlled, when methane-generating pit temperature is lower, open ball valve, solar water carries out thermal exchange with proferment feed liquid by different transfer of heat in spiral heating coil pipe, and the solar water after temperature reduces is back to water tank.The moon, rain, snow weather sunshine amount is not enough time, for ensureing that this system still can run well continuously, now open the electric heater in hot water storage tank, water temperature reaches auto-breaking after set(ting)value.This solar-energy methane pit improves methane-generating pit Biogas production during winter rate by solar heat water cycle and electricity heating technology, reduces the fluctuation range of methane-generating pit air demand throughout the year, improves the fermentation gas rate of biogas.
