The invention relates to a methane production device without energy consumption suitable for a cold region in winter and belongs to the field of environmental protection and renewable energy sources. A reactor is designed into a vacuum sandwich structure and can reduce heat loss; a heat storage water tank is arranged on the lower part of the reactor and has an effective energy storage function; a solar heat collecting pipe is arranged at the bottom of the reactor, heat is directly transferred without adopting pump circulation, and energy-saving and warming effect is good; an emergence electric heater is arranged in the water tank and can compensate warming in cloudy day; a single blade is spirally propelled into a stirrer, the driving is convenient and labor-saving and the stirring effect is good; and a turning hopper is driven by a steel rope to feed, so that the feeding is convenient. The whole set of device has a good effect of warming and keeping warm, has convenience in operation, consumes no additional energy source, is high in methane yield, and can ensure the normal use in the cold region in winter. |
