Embodiment Construction
[0023] As shown in the figure, the non-energy-consuming biogas production device in winter in this cold region is mainly composed of a feed device 1, an anaerobic reactor 4, a heat storage tank 11, a solar vacuum heat collection tube 8, an agitator 3, an external tank insulation 16, a discharge Material system composition. Put down the shading plate of the solar vacuum heat collecting tube 8 before operation to reduce its temperature, and when the temperature of the solar vacuum heat collecting tube 8 drops below 40°C, fill the water storage tank 11 with water to prevent the solar vacuum heat collecting tube 8 from When the temperature is too high, the cold water bursts, and the liquid level gauge 13 is observed until the water storage tank 11 is filled with water. Mix the feces with the cut straw, mix according to the C / N ratio of 25:1, add a small amount of water, cover with plastic film, stack retting for 3 to 5 days, and then start feeding. When feeding through the feeding...
