Embodiment 1

[0026] figure 1 It is a schematic structural diagram of a biogas digester provided in the embodiment of this application.

[0027] Such as figure 1 As shown, 1 in the figure is the pool body of the biogas digester. In the embodiment of the present application, the biogas digester body 1 includes: inner layer 2, outer layer 3, insulation layer 4 and anti-seepage layer 5, wherein: anti-seepage layer 5 , the inner layer 2, the insulation layer 4 and the outer layer 3 are distributed sequentially from the inside to the outside.

[0028] The inner layer 2 and the outer layer 3 are enclosed to form a space with an opening at the top, such as figure 1 As shown, the opening is 6, and a gas output device may be provided on the opening 6 for outputting the biogas generated in the biogas digester body 1 to the user. The inner layer 2 and the outer layer 3 are sealed, that is, there is a gap between the inner layer 2 and the outer layer 3 . In the embodiment of this application, accor...

Embodiment 2

[0034] In the last embodiment, a thermal insulation board is installed in the biogas digester to reduce the temperature diffusion rate in the pond, but this premise is that the temperature in the pond is relatively high, and when it is in winter, the temperature of the biogas liquid in the pond itself is relatively low, then At this time, using the insulation board alone cannot guarantee the temperature of the biogas slurry in the biogas digester. For this reason, the embodiment of the present application also provides another biogas digester.

[0035] Such as figure 2 As shown, on the basis of Embodiment 1, the digester body can also include: a warming coil 7 and a circulation pump 8, wherein:

[0036] Warming coil 7 can be arranged between the insulation layer 4 and the inner layer 2 at the bottom of the biogas tank body (such as figure 2 As shown), it can also be arranged between the thermal insulation layer 4 and the inner layer 2 of the side wall of the biogas digeste...

Abstract

The present application discloses a biogas digester. The body of the biogas digester includes: an anti-seepage layer, an inner layer, an outer layer and a thermal insulation layer, wherein: the inner layer and the outer layer both form a space with an opening at the top, so The inner layer and the outer layer are sealed, and the anti-seepage layer is fixed on the entire inner wall of the inner layer; layer and the outer layer. Compared with the prior art, the inner wall of the biogas digester provided by the embodiment of the present application is provided with an insulating layer, which can reduce the temperature diffusion rate of the biogas digester, improve the thermal insulation effect, facilitate fermentation, and increase the gas production speed and efficiency.

Description

technical field [0001] The application relates to the technical field of biogas, in particular to a biogas digester. Background technique [0002] As a new clean energy, biogas can be widely used in rural areas of our country. It uses the waste straw of crops to produce biogas as an energy source for cooking, heating water, lighting, etc., which can save a lot of coal, fuel and Firewood, etc., and can improve the environment, high thermal efficiency, so it is valued by the relevant departments. [0003] Due to the great influence of temperature during fermentation, the gas production of existing biogas digesters changes with the seasons. Biogas is produced normally. And when the temperature is lower than a certain temperature (generally below 15°C), especially in the biogas digesters in the permafrost layer in winter, the fermentation speed is relatively slow, usually 3 days after the feed can produce gas, the gas production speed and efficiency Low, can not produce gas n...
