Solar assisted methane fermentation device

Abstract

The invention discloses a solar assisted methane fermentation device which is characterized in that a set of solar hot water device and a hot water circulating pump are also arranged above the original anaerobic fermentation tank, the inlet of the pump is connected with a lower outlet of a water collecting box of the solar hot water device, the outlet of the pump is connected with a heat radiator which is arranged in the fermentation tank, and the outlet of the heat radiator is connected with the water inlet of the hot water collecting box, so that the solar heat is transferred to the fermentation stock solution to promote the continuous operation of anaerobic fermentation, thereby effectively ensuring stable fermentation temperature and constant gas output and improving the level and the quality of life of rural residents.

Description

1. Technical field [0001] The invention relates to a device for continuous fermentation of methane assisted by solar energy, which belongs to the comprehensive utilization of environmental protection and energy saving technology. 2. Background technology [0002] Biogas engineering technology using poultry manure for anaerobic fermentation is an important link in the rural ecological chain that realizes plant growth, animal transformation, and microbial reduction. Utilizing poultry manure for anaerobic fermentation produces biogas for use by rural residents. After fermentation is completed The biogas residue liquid can be used to fertilize fields and improve soil, and promote the growth of agricultural plants. The traditional anaerobic fermentation biogas production process is carried out using natural conditions. Since anaerobic fermentation is greatly affected by the ambient temperature, the fermentation temperature is often more suitable when the temperature is high in su...

AI Technical Summary

Problems solved by technology

The traditional anaerobic fermentation biogas production process is carried out using natural conditions. Since anaerobic fermentation is greatly affected by the ambient temperature, the fermentation temperature is often more suitable when the temperature is high in summer, and the gas production can meet the needs of residents for gas consumption. However, under winter conditions, the ambient temperature is relatively low, and the temperature of the corresponding anaerobic fermentation is also relatively low, so the fermentation cannot be carried out normally, and the gas production is small, which cannot meet the needs of residents for gas consumption; therefore, residents cannot Normal use of gas, sometimes often cut off and affect the quality of life of residents

In order to ensure the normal use of gas by residents, it is necessary to ensure suitable conditions for fermentation. First of all, to maintain a suitable temperature for fermentation. Using electric energy or other artificial energy to ensure the fermentation temperature will increase the cost of gas production and affect the living standards of rural residents.
