Embodiment Construction
[0009] Embodiments of the present invention are given below in conjunction with the accompanying drawings.
[0010] An existing biogas digester structure is injection molded or welded with plastic materials including figure 1 Shown is a biogas digester comprising a fermentation room 1, a water pressure room 2, a feeding port 3, a slag outlet 4, two layers of walls and a bottom forming an interlayer 5. Make and comprise the solar water heater of heat collecting pipe 6, heat collecting plate 7, upper circulation pipe 8, lower circulation pipe 9, water storage tank 10 and water inlet and outlet pipes. A biogas burner 11 is installed on the back side of the heat collecting plate 7 . Fix the solar water heater on the ground or on the roof. The solar water heater is installed in the windproof insulation box. Connect the water supply pipe 12 and the water return pipe 13 between the solar water heater and the interlayer of the biogas digester. A circulating water pump 14 is instal...

The invention relates to a solar constant temperature fermentation biogas tank which pertains to the field of biochemistry, can eliminate the effect of natural environment on fermentation temperature and overcomes the disadvantages that the current biogas fermentation tank is unstable in output and even cannot produce gas in cold areas. The made improvement is that the wall or the wall and the bottom of the fermentation tank are two-layered and an interlayer for circulating water is formed between the two layers. A solar water heater is added. The interlayer connecting the solar water heater and the fermentation tank forms a water circulation circuit. A water pipe is provided with a pump. A biogas burner is arranged at the back of the absorber plate of the solar water heater. The pump andthe biogas burner are controlled by a temperature sensor and a temperature signal processing circuit which are positioned in the fermentation tank and the water heater. The fermentation biogas tank of the invention has the advantages of utilizing the solar water heater and circulating water in the interlayer under particular cases, in which the fermentation tank is the biogas tank to heat and preserve heat, to realize the fermentation of the fermentation biogas tank under the optimum temperature condition, thus offsetting the unfavorable effects of the change of natural temperature on the fermentation and obtaining the effect of stable and high efficient biogas production in cold areas where temperature changes greatly.
Description
technical field [0001] The invention belongs to biochemical technology, and in particular relates to a methane constant temperature fermentation device. Background technique [0002] Promoting the production of biogas in rural areas is a good thing that benefits the country and the people, and it is well known. The obtained gas fuel and high-quality organic fertilizer can not only promote the improvement of rural life civilization. It is especially beneficial to environmental protection. It can eliminate the direct pollution of the environment caused by excess straw, human and animal manure and organic domestic waste. It can also replace excessive chemical fertilizers by increasing the amount of organic fertilizers, in addition to reducing the degradation of the soil caused by chemical fertilizers. In addition to pollution caused by surface water, it can quickly restore and improve soil fertility, produce high-quality crops, and improve human health. Relevant national depa...
