Heating device of fermentation box in methane generating device

Abstract

The invention provides a heating device of a fermentation box in a methane generating device, which belongs to the technical field of methane fermentation, and solves the technical problems that an existing methane generating device adopts electric heating pipes to heat, so that electric energy is wasted and the like. The methane generating device comprises a methane collecting box, the fermentation box and a feed hopper, wherein a collecting cavity is formed between the fermentation box and the methane collecting box, the middle part of the fermentation box is provided with a spherical hollow cavity, the bottom of the fermentation box is communicated with a discharge pipe and a liquid outlet pipe, and the other ends of the discharge pipe and the liquid outlet pipe penetrate through the methane collecting box and then are communicated with the outside. The heating device of the fermentation box in the methane generating device comprises a water inlet pipe, a heat dissipation pipe and a water outlet pipe, wherein the heat dissipation pipe is in the fermentation cavity of the fermentation box, the water inlet pipe is communicated with one end of the heat dissipation pipe, the water outlet pipe is communicated with the other end of the heat dissipation pipe, and the water inlet pipe is higher than the water outlet pipe. The heating device provided by the invention can be used for continually heating the fermentation box.

Description

technical field [0001] The invention belongs to the technical field of biogas fermentation, and relates to a biogas generator, in particular to a heating device for a fermentation box in the biogas generator. Background technique [0002] As a clean energy, biogas has been widely used in various fields by human beings. The main raw material of biogas is crops such as straws. Due to the wide sources of crops and the large amount of resources, the content of biogas is also very rich. At present, a large amount of crop waste such as straw has not been effectively treated, which has brought about a series of environmental problems and seriously threatened the human environment and development. This problem can be effectively solved by biogasizing crop waste such as straw, and at the same time, high-quality bioenergy—"biogas" can be produced, which has very high economic value. [0003] At present, humans usually use biogas generators to produce biogas, but the biogas productio...

AI Technical Summary

Problems solved by technology

[0003] At present, humans usually use biogas generators to produce biogas, but the biogas production is usually limited, for example, it will affect the biogas production with seasonal temperature changes or day and night temperature changes

Under normal circumstances, when the temperature inside the biogas generator is greater than 15°, biogas can be produced normally, and when the temperature inside the biogas generator is lower than 15°, the biogas yield is very low, or even no longer produces biogas

[0004] In the existing technology, the biogas generating device can generate heat by heating with electric heating tubes, but the electric heating tube has the disadvantage of wasting electric energy. Therefore, for those skilled in the art, the existing biogas generating device needs to be improved. , so that biogas fermentation can have a better gas production environment, thereby improving production efficiency and producing more clean energy for human beings
