Automatic temperature control methane fermentation device

Abstract

The invention discloses an automatic temperature control methane fermentation device. The device comprises a fermentation tank, a shell, a heat exchange tube, a heating system, a cooling system, a first temperature sensor, a control template and a methane pressure probe, wherein the shell is arranged on the periphery of the fermentation tank to form a cavity structure, and a middle hot water layer is arranged in the cavity portion; the heat exchange tube is wound around the outer wall of the fermentation tank in a spiral mode, and the two ends of the heat exchange tube are communicated with the heating system and the cooling system to form a circuit; a first water pipe gather junction and a second water pipe gather junction are arranged at the positions where the heat exchange tube is connected with and intersects with the heating system and the cooling system respectively, a water pump, a heating water valve and a cooling water valve are arranged on the heat exchange tube, and the first temperature sensor is arranged on the outer wall of the fermentation tank; the methane pressure probe is arranged in a methane storage bag, and the control template is connected with the first temperature sensor, the water pump, the heating water valve, the cooling water valve and the methane pressure probe. An automatic control device is adopted, and relative stability of the yield and quality of methane is guaranteed.

Description

Technical field [0001] The invention relates to an automatic temperature-controlled biogas fermentation device. Background technique [0002] As a bioenergy with relatively low production technology and easy promotion, biogas is strongly recommended by the country and widely promoted across the country. However, our country has a vast territory and environmental factors vary greatly. In some areas, the temperature difference between summer and winter is large. Biogas production, both in terms of output and quality, is easily affected by ambient temperature. Contents of the invention [0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention aims to provide an automatic temperature-controlled biogas fermentation device. [0004] Technical solution: In order to solve the above technical problems, the present invention adopts the following technical solution: [0005] An automatic temperature-controlled biogas ...

Problems solved by technology

[0002] As a bioenergy with relatively low production technology and relatively easy promotion, biogas has been strongly recommended by the state and has been widely promoted throughout the country. However, my country has a vast territory and large differences in environmental factors. In some areas, the temperature difference between summer and winter is large. However, the production of biogas, whether it is output or quality, is easily affected by the ambient temperature.
