Embodiment 1

[0020] Example 1. As shown in Figure 1, the integrated anaerobic fermentation device for gas production and gas storage of the present invention has a cylindrical tank body 5 of a PVC composite film, and the tank body is provided with a feed port 1, a discharge port 2, and a slag discharge port 3 With the biogas outlet 4, the biogas outlet is connected with a safety water seal 12 in parallel. The outermost part of the tank roof is a PVC composite film hemispherical pressurized film 8 to form a spherical crown; There is a PVC composite membrane flexible air storage membrane 6 in the spherical crown, and a sealed chamber is formed between the two layers of membranes. The upper edge 16 of the tank body 5 has a matching annular fastening bead 13, and the bolt 14 passes through the compression block to compress the air storage film 6 and the pressurized film 8 on the edge through the sealing plate 17 to achieve airtightness (see figure 2). An air storage chamber 7 is formed betw...

Abstract

The invention relates to an gas production and gas storage integrated anaerobic fermentation device which needs to solve the problems of reducing the manufacturing costs of fermentation device top, improving the heat preservation, stabilizing the gas supply and enhancing the gas production by fermentation. The fermentation device has a tank volume which is characterized in that: the top of the tank has a flexible storage gas film; a storage gas chamber is disposed between the storage gas film and materiel surface; pressure film is out of the storage gas film; a gas-tight chamber is formed between two films; the gas-tight chamber connects to the pressure device. The tank volume has a blender at lower part, and a backflow device with a pump on the body. The upper mouth of the backflow pipe is higher than the material surface.

Description

technical field [0001] The invention relates to an integrated anaerobic fermentation device for gas production and storage, which is especially suitable for the treatment of high-concentration livestock and poultry manure in the biogas engineering of farms. Background technique [0002] At present, in the biogas project of farms, the reactor for treating livestock and poultry manure treats manure concentration TS<8%. When the concentration of livestock and poultry manure increases to TS 8-12%, the mass transfer in the fermentation feed liquid is affected. A dead zone appears, which is easy to acidify, accompanied by phenomena such as scum and crusting, which affect the digestion efficiency of the reactor. Moreover, in the biogas project, in addition to the above-mentioned reactors, it is also necessary to build a gas storage tank to store the generated biogas, which makes the project occupy a large area and invest a lot.
