Embodiment Construction

[0024] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0025] In the present invention, in the case of no contrary description, the used orientation words such as "up, down, left and right" usually refer to the up, down, left and right shown in the accompanying drawings; "inside and outside" It refers to the inside and outside with respect to the outline of each part itself.

[0026] It is difficult to discharge the biogas residue in the existing dry-type straw fermentation device, and generally the biogas residue cannot be exhausted, which is not conducive to subsequent feeding, and also has a certain impact on the continuous gas production, or the structure of the slag discharge part of the fermentation device is ...

Abstract

The invention relates to the field of straw biogas, and discloses a fermenting device and straw biogas system. The fermenting device comprises a fermenting tank (1), a discharge pipe (2) arranged below the fermenting tank and a high pressure fluid pump (3) connected to the discharge tube, wherein a fluid flows in the discharge pipe at a high speed; a plurality of truncated discharge ports (11) for discharging biogas residues are formed in the bottom of the fermenting tank and the small ends of the truncated discharge ports communicate with the discharge pipe. According to the fermenting device and the straw biogas system provided with the same provided by the invention, the truncated discharge ports are formed in the bottom of the fermenting tank, so that biogas residues are centralized at the truncated discharge ports; the small ends of the truncated discharge ports communicate with the discharge pipe, and the high pressure fluid pump is connected to the discharge pipe, so that the fluid flows in the discharge pipe at the high speed to form negative pressures at the truncated discharge ports, and therefore, the biogas residues are easily and smoothly discharged and exhausted, and follow-up feeding is facilitated and the gas-yielding amount is improved; and meanwhile, the fermenting device is simple in structure, convenient to operate and relatively low in cost.

Description

technical field [0001] The invention relates to the field of straw biogas, in particular to a fermentation device and a straw biogas system with the same. Background technique [0002] Straw biogas refers to a combustible gas produced by anaerobic fermentation of microorganisms under strict anaerobic environment and certain temperature, moisture, pH and other conditions using biogas equipment and using crop straw as the main raw material. As a clean, convenient and cheap new energy source, straw biogas has broad development prospects and lays a solid foundation for the development of ecological countryside. At present, my country's economy is in a stage of rapid development, and the demand for resources is gradually increasing, while the per capita resource volume in my country is far below the world average level. Straw biogas will solve the demand for coal, oil and other fuels to a certain extent. , making a major contribution to breaking through the resource bottleneck of...
