Abstract

The invention relates to a biogas generation system. The biogas generation system comprises a raw material workshop and a fermenting workshop, wherein the raw material workshop comprises a loading rail, a steering rail, a transverse return rail and a vertical return rail which are connected in a head-to-tail way; the fermenting workshop comprises a material stacking plate, a biogas tank and an outer cover; the biogas tank comprises a left inclined bottom casing, a right inclined bottom casing, a top plate of the biogas tank and a fermenting cavity; the inner ends of the left inclined bottom casing and right inclined bottom casing are connected; the outer ends of the left inclined bottom casing and right inclined bottom casing are connected with the top plate of the biogas tank through a material inlet and an upper wall passage of the material inlet; the heights of the left inclined bottom casing and right inclined bottom casing are gradually increased from the inner ends to the outer ends; a biogas accommodation cavity is clamped between the top plate of the biogas tank and the material stacking plate; the fermenting cavity is communicated with the biogas accommodation cavity through a gas ventilating port; a slag intake passage is arranged at the middle parts of the top plate of biogas tank and the material stacking plate and just vertically faces the crossing part of the leftinclined bottom casing and right inclined bottom casing. By adopting the design, the biogas generation system has the advantages that the mixing degree of biogas slurries is high, the mixing uniformity between the raw materials is better, the working efficiency and biogas production efficiency are higher, the interference between the slag intake and biogas production is avoided, and the slag intake efficiency is higher.

Description

technical field [0001] The invention relates to a biogas production technology, which belongs to the field of biogas fermentation, and in particular to a biogas generation system and a production process, which are specifically suitable for improving work efficiency, increasing the mixing uniformity between raw materials and biogas liquid, and between raw materials, and improving Gas production efficiency. Background technique [0002] With the development of my country's agriculture, the amount of straw waste produced is increasing, and random waste or burning of straw will easily pollute the environment. Therefore, it has become a consensus to use straw for biogas fermentation. At present, the fermentation raw materials used in most biogas projects in China are in the liquid state of poultry manure. Therefore, most of the feeding devices used are liquid pumps. This type of feeding device limits the solid content to 5%. The particle size is about 2 cm. If the pure straw ra...
