Intestinal-tract type biogas generating system

Abstract

The invention discloses an intestinal-tract type biogas generating system, and belongs to the field of biogas production devices. The intestinal-tract type biogas generating system comprises a multiple-entrance feeding device, an intestinal-tract type fermentation pipe path and a biogas collecting device. The multiple-entrance feeding device mainly comprises a plurality of sewage collectors which are arranged at a high place, collecting pipes connected with the sewage collectors and a total feeding pipe. The intestinal-tract type fermentation pipe path comprises a pipe storage chamber which is deeply digged underground, and multilayer-overlaying fermentation pipelines, wherein the fermentation pipelines are buried underground, and are bended and spiraled like the intestinal tract. A feeding port of the fermentation pipelines is connected with the total feeding pipe. The biogas collecting device comprises a plurality of biogas collecting pipes and a gas storage component, and the plurality of biogas collecting pipes are respectively leaded out from a plurality of gas taking ports of the uppermost fermentation pipeline. Through use of the intestinal-tract type biogas generating system, organic materials such as excrements and the like can be fully fermented, automatic feeding, automatic feed-discharging, automatic separating of the materials, and automatic conveying of the materials to the fields can be realized, and no caking and no slag is produced, so that the intestinal-tract type biogas generating system is energy saving and environmentally friendly.

Description

technical field [0001] The invention relates to a biogas digester, in particular to an intestinal type biogas generating system which breaks through the traditional design mode of a biogas digester. Background technique [0002] At present, the biogas digesters that are being widely used are all circular or square, polygonal, and tunnel-shaped container-type biogas digesters with large inner diameters. Because the biogas residue stays in the fermentation room, it is difficult to ensure the control of feed and discharge due to the large diameter of the pond. The material is first in, first out, and it is not easy to control the full fermentation cycle time of the material in terms of time, so the feces and other materials are discharged without sufficient fermentation, so that the biogas production rate is not high, and some of the discharged materials are fully fermented, and some Semi-fermentation, the odor is not completely eliminated, and the bacteria are not completely k...

AI Technical Summary

Problems solved by technology

It is troublesome to feed the existing biogas digesters. The raw materials have to be transported to the biogas digesters by trailers, etc., and cannot be automatically fed.

Existing biogas residues are fermented to separate residues from liquids using presses, etc., which are costly and consume a lot of energy. Due to the particularity of the processed materials, the equipment is prone to failure, which is very troublesome.

Due to the limited space of the fermentation tank, the existing biogas digesters can only ferment feces and other excreta, and cannot ferment domestic sewage. Domestic sewage cannot be recycled and needs to be treated separately by sewage treatment facilities. In rural areas, domestic sewage is not concentrated. Disposal, disorderly row phenomenon is serious, affecting environmental sanitation

Now, many farmers respond to the call of the state to build this kind of container-type biogas digesters. They often break down after about 2 years of use, and produce little or no gas, so they are discarded, causing great waste.

Some existing patented technologies such as the "labor-saving and automatic slag discharge biogas digester" with the application number of 201210189261.3, and the "high-efficiency biogas digester and biogas production process using livestock and poultry manure" with the application number of "201110373294" can only be aimed at One or two of the above problems can be solved permanently, and facilities and equipment need to be added, the structure is complex, and the structure of the container biogas digester has not been changed substantially. There is no existing technology that can solve all the above problems
