Biogas generator applicable to cold regions

Abstract

The invention discloses a biogas generator applicable to cold regions, which is mainly characterized in that: a guiding stirrer and a scrambler are arranged inside a biogas fermentation tank of a biogas pool, the guiding stirrer is located at the periphery of the biogas fermentation tank, the scrambler is located at the center of the biogas fermentation tank, the guiding stirrer and the scramblerare communicated, the guiding stirrer and the scrambler are communicated with a heat-insulation and heating controller, the heat-insulation and heating controller is connected with a gas collection tank through a gas pump, an adjusting valve and an electromagnetic valve and a shell breaking cone is located at the top of a floating cover of the biogas fermentation tank; the heat-insulation and heating controller can control the temperature of the fermented liquid, thus achieving the heat insulation and heating of the fermented liquid, protecting the fermented liquid from the outside temperature influence, reaching the optimum temperature for bacterium fermentation and facilitating the production of the biogas; and the guiding stirrer, the scrambler and the shell breaking cone utilize a gasdisturbing mode to carry out strong forced movement on the fermented liquid and reach a turbulent state, thereby destroying the crusting of plant fibers, completely decomposing the fermentation raw materials and increasing the gas production rate of the raw materials.

Description

technical field [0001] The invention relates to a biogas generating device, in particular to a biogas generator suitable for cold regions which integrates biogas fermentation, biogas slurry heat preservation, stirring, and biogas storage and transportation. Background technique [0002] As a renewable energy source, biogas has become a comprehensive system integrating multiple benefits such as energy, ecology and environmental protection. The development of rural biogas projects not only provides farmers with clean energy and high-quality organic fertilizers, but also solves the problems of crop straw, human and animal manure. It has far-reaching significance in improving the rural ecological environment, improving the quality of rural life, increasing farmers' income, and developing ecological agriculture. [0003] The temperature conditions of the biogas digester are divided into: ① normal temperature fermentation (also known as low temperature fermentation) 10 ℃ ~ 30 ℃, ...

AI Technical Summary

Problems solved by technology

[0004] In the cold area of ​​northern my country, due to the long winter time and low temperature, the gas production rate of the biogas digester is low. When the temperature is lower than 10°C, it does not even produce gas, which makes the biogas digester unable to be used normally in winter.

At the same time, because the fermented raw materials are mixed with cattle, horses and other herbivorous livestock manure (in the northern region), the plant fibers lead to the encrustation of the biogas slurry is more common, thereby inhibiting gas production, which limits the promotion and application of biogas technology in northern my country
